What Happened to Abit Motherboards

The Abit BP6 taught me so much about multithreaded programming. Programs that previously worked fine crashed instantly due to incorrect locking. It really forced me to think differently about concurrent programs.

After that I never found multithreaded programming particularly difficult. Challenging at times yes, but thanks to my newfound mental model not difficult.

I had those brass-looking cylindrical coolers[1] from Zalman, and the two of them next to each other was quite distinctive.

Had the motherboard for many years as a homelab server.

I bought a few more Abit boards after that, but the capacitor plague made me switch to Asus IIRC, and then they folded.

But the BP6 will forever be with me as a incredibly cool motherboard that did something unique in the consumer space.

Exactly like that, yes!

Ran the Celerons overclocked, as one did, and supposedly those were superior in thermals vs noise. Not that I had any reference.

Those are actually Thermaltake Golden Orbs, although many companies made similar designs.

As impressive as they look, and as effective as they were at the time, I believe even a modern stock Intel cooler would be more effective; CPUs of the time only had TDPs around 20-30W, in comparison to the 100W+ they are now at.

> Thermaltake Golden Orbs

You are 100% correct, how could I forget? :(

I think I got it mixed up because I bought a Zalman GPU cooler which had similar design for my GPU some years after.

Thanks for the trip down memory lane.

Nice, I worked at one of those mom and pop computer shops in the late 90's. I built the computers, and I even went with my boss (the shop owner) to those shows a couple times. From what I remember, the show scene was pretty well declining at that point, at least in our area. I still remember the TV ads, though. "SUPER VGA! CD-ROM!!"

lots of cool 'engineering art' around heat-sinks and exchangers, for sure. Check out some of these shapes [0] , i'd love to have one on a shelf as a talking piece.

The coolermaster cpu sink i'm using now is big, but not particularly pretty.

The super socket 7 motherboards were amazing.

They were backwards compatible with socket 5 (you had to set the motherboard jumpers voltages though).

Some of these boards had both sdram and edo ram slots along with an agp slot, pci slots and an isa slot.

So you had an era where motherboads could take a P-75 or an amd k6 550 cpu. They could take ram scavanged from an old 486 (edo ram) or you could put in faster ram. You could run a pci grapchics card if it’s all you had or you could run an agp card. I used my old 486s isa soundblaster awe in that board for a long long time since pci was of no benefit for a soundcard.

The only set of cpus not compatible were the slot and socket 370 cpus. But they were pretty expensive anyway and it was fun to be able to frankenstein computers so much back in the day.

I did love that era, in terms of it providing a young frugal person with the opportunity to buy upgrades piecemeal. It felt like there was more generational overlap, as you describe, so it was possible to just go out and buy a new CPU, or a new graphics card, for a few hundred carefully saved dollars of birthday and christmas money, and get a sizeable upgrade in performance. That era is over, especially with the current pricing crunch.

What I am hoping for is that this leads to a resurgence for all those used computers out there... plenty of great machines from the last decade that should have no problem being competent workstations for 90% of people's needs for the next decade onward if treated well. This is where open standards and open source truly shine.

It was an era where there was actual competition in the motherboard space as different vendors tried to outdo each other with their northbridge and southbridge and especially the connection between them. Computer magazines at the time actually benchmarked motherboards. Then Intel and AMD slammed the door shut on that market by moving the important functionality into the chip and now nobody cares about the motherboard very much.

> ram scavanged from an old 486 (edo ram)

EDO was from the 2nd generation of Pentium. It was not a 486 thing and I never even heard of any 486 that could use EDO.

The 1st gen Pentium chips were 5V parts running at 60 MHz or 66 MHz.

The 2nd gen were 3.3V and ran at 75, 90 or 100 MHz.

The critical development for EDO was Intel's Triton chipset (the 82430FX) which added EDO support for about 15% more memory bandwidth.

I ran the testing labs for PC Pro magazine at that time and Tulip Computers of the Netherlands sent in a Pentium with an SIS chipset that could detect EDO but not use EDO's timings, so it was no quicker. I wrote about it.

(This was circa 1995. 486 introduced 1989. P5 (5V) 1993. P54C (3.3V) 1994.)

Tulip threatened to sue. The board and some lawyers flew to London. I demonstrated that their PC could detect EDO and showed a message that EDO was fitted which did not appear if FP-mode DRAM was.

I then showed that a machine with a 430FX chipset was circa 15% quicker with EDO than FP RAM, and the Tulip was the same speed.

The threat of litigation was withdrawn and Tulip used our phone to make an international call to Taiwan there and then to shout at SIS.

I worked extensively with this stuff.

No 486s with EDO to the best of my expert knowledge.

by lproven

1/1/2026 at 4:01:11 PM

A lot of SIS chipsets claimed EDO support, but with such bad timings there was no gain or even loss https://www.vogons.org/viewtopic.php?p=1378307#p1378307 "I see no performance difference between EDO and FPM"

Legit 486 EDO chipset is UMC 8881E/F https://www.vogons.org/viewtopic.php?t=93147 "486 board with UMC 8881E/8886B: The winner is: EDO without L2 (if your only other option is L2 at 3-2-2-2)"

TLDR: standard on any 486 motherboard L2 cache masks any EDO mode gains, even when EDO runs with fastest supported 3-1-1-1 timings.

Pretty sure I had a Pentium 4 mobo that was kind of like that in 2002-2003 timeframe. Was still rocking my old ISA Sound Blaster 16 (the big ass one with the connector for a CD-ROM drive) alongside a Radeon 7500 in the AGP slot.

It wasn't much but I could run Alice, Max Payne, GTA 3, Dungeon Siege on there, all at like mid settings, so I was a pretty happy camper for a high school kid putting paper route money into my own PC.

by mikepurvis

12/30/2025 at 6:21:57 PM

ISA slots were definitely rather rare on motherboards by the time you got to the Pentium 4 era, so that's cool that you managed to find one that also offered DMA, since I believe Sound Blaster cards needed that to properly function.

I think I would have done the same with my AWE64 Gold if that was still an option for me in the early 2000s.

by TheAmazingRace

12/30/2025 at 8:00:09 PM

Having googled it a bit now, it's fully possible I have my wires crossed, since I know that P4 machine had the SiS 645 chipset which of course had built in audio.

I definitely used the Sound Blaster with my 486DX100, and I recalled migrating it to at least one other machine after that; it was nice for the joystick port and also the better wavetable synth on classic games.

by mikepurvis

12/30/2025 at 8:26:39 PM

I posit the opposite. Super Socket 7 motherboards were a terrible choice aimed at suckers trapped by sunk cost fallacy.

>along with an agp slot

Non working AGP slot, or rather working until you tried to play 3d games with 3D accelerator actually using AGP features, then you got crashes no matter the chipset (VIA, ALI). Solution was switching to x1 mode, disabling sideband signaling or just swapping to a 3dfx card.

1998 with the release of Intel Celeron killed any possible K6 advantage https://akiba-pc.watch.impress.co.jp/hotline/981226/p_cpu.ht... ~120 yen to $1

You are comparing bottom of the barrel AMD CPUs with top spec Pentium 3s. Correct comparison should be against Celerons. January 2000 prices https://akiba-pc.watch.impress.co.jp/hotline/20000617/p_cpu....

$76 K6-2/550 is slower than $73 Celeron 366, not to mention pulverized in benchmarks if you happened to find Celeron capable of 100MHz fsb.

Old slow ram makes K6 setup even slower. You would think the benefit were much cheaper motherboards, but even that wasnt the case. SS7 boards started at ~$75 while Abit BE6-2 was $90 and cheapest 440BX ones (P2XBL) $65. K6-2/550 3DNow! (100MHz Bus) $90 vs Celeron 500 $93 https://archive.org/details/computer-shopper-2000-07/page/n3...

Slot1 made much more sense, only release of K7 made AMD competitive again with Duron on the low end and Athlon way ahead of P3.

What a story. This brings back memories and ties directly into my life.

In fall of 1999, I built my first PC with an Abit BE6 to use with an Intel Pentium 3 'Coppermine' 500 MHz. I was a fifteen year old kid working at pizzeria in the midwest making minimum wage to feed my computer hobby. At the time I was reading hardocp, and compiled a list of "good" BX motherboards to try and find at computer show that was organized on a semi-regular basis at the local fairgrounds. This event saw numerous mom&pop computer stores travel from hours away to sell custom PCs, software, and hardware. I remember having a bit of buyer's remorse because I actually wanted the BE6-II which featured the ability to change the front side bus in 1 MHz steps, while the older BE6, only had a set of fixed multiplers and PCI dividers. My 500 MHz coppemine (5 x 100 MHz) didn't post at 750 MHz (5 x 150 MHz) and was unstable above 667 MHz (5 x 133 MHz). This overclock still 'saved' me a considerable amount of money by allowing me to purchase the cheapest part and squeeze performance out of it. That computer hobby led me down a path of studying computer engineering and my eventual departure (escape) from the Midwest.

Years later, in 2015 I moved to Taipei, and remember walking around Neihu seeing all the headquarters of the computer part manufacturers I used in my childhood (Liteon, ECS, Nvidia). I didn't realize that Abit's former headquarters on 陽光街 is right next to many of the places I've been living and working next to for the past decade.

Another memory from that time was buying 128 MB of SD-RAM from Crucial (Micron). I remember being a little pissed because the price had gone up 50% due to the 921 earthquake, which killed thousands and left many homeless, and knocked the fabs offline which led to a supply shortage.

So much to relate to here. Midwest, HardOCP (and their folding team), local store was MicroXPress (Indianapolis), just sub Staples for the pizza gig.

Also vividly recall buying my first Bigfoot HDD, which I think was multiple GB, thinking I'd never have use for any more storage...

by adamw2k

12/30/2025 at 5:26:20 PM

Interesting read. I had the Abit BP6 and it was a killer in performance/price. The problem I had with it wasn't the capacitors but rather that the PCB itself was a bit thin to support 2x CPUs/fans.

Another cool thing was that the BP6 supported Ultra DMA/66 (aka ATA/66) and it did so by adding a second controller so you had twice as many buses. Looking a pic of it now, it really was a Franken-machine with AGP, PCI, ISA busses too.

by karmakaze

12/30/2025 at 5:43:18 PM

Yes, mine bowed eventually even though I put non conductive closed cell foam under the cpu areas.

Still, I made good on my promise to never return to single core machines.

by itomato

12/30/2025 at 6:58:43 PM

When I used the Abit BP6 in a Linux box build, I did it as a one-Celeron budget PC with expandability, and put some notes on the Web at the time:

https://www.neilvandyke.org/cheap-pc-2000/

That page includes pricing info for each component, and how I bought it. For example:

> Abit BP6 Dual PPGA Socket-370 motherboard, UDMA-66, 2 ISA, 5 PCI, AGP 2X, 3 168-pin PC100 ECC, max. 1GB RAM. Retail version. (Essential Computing $120 + $14.25 UPS Ground + $3.60 insurance = $137.95)

> Intel Celeron 500 Retail version, with warranty and CPU fan and heat sink. (Egghead $135.99 + free UPS Ground = $135.99)

The box was my workstation, and for a time also a public Web server on ADSL. I never actually added a second Celeron (cost money, and I still wasn't feeling CPU pressure) nor the UDMA-66 (reported to be less reliable).

An Abit AV8 was my first "Good" new motherboard. I came into some money and decided to build a then-new Socket 939 setup, with a 3200+.

I recall they had one BIOS release that bricked boards, which I missed by not downloading it the first day of availability. The board was eventually destroyed by a sketchy PSU which killed the AGP slot and the Geforce 6800LE that was in it.

Later I tried an IP35-E, but had problems (two different memory sets failed) so I returned it for the Gigabyte P35-DS3L I actually wanted but was out of stock at the time.

by hakfoo

12/30/2025 at 5:56:26 PM

Ah, I kept that BP6 for 10 years before selling it. It meant I could write multithreaded concurrent software and run it at home with LinuxThreads (https://en.wikipedia.org/wiki/LinuxThreads) then NPTL (native Posix threading lib).

Mine was not very stable under even moderate overclocking though!

Good times!

A friend of mine won an Athlon XP in a forum contest, I think it was Extreme Systems or Extreme Overclocking. He ended up pairing it with an Abit NF7-S, which I recall being a legendary board at the time. He brought it over to my place and we would LAN Unreal Tournament 2003. Those were the days!

by whalesalad

12/31/2025 at 3:34:02 AM

Ah, I remember scheming about buying an NF7-S + an Athlon XP Barton and unlocking it, combining it with a geforce 4 ti4200 and overclocking both but not even having enough of the pocket change to pull that off. By the time I was far enough along to have some of that in school, I picked up an A64 and a top of the line Geforce 5 from a black friday sale and had a great time gaming and coding.

Ironically, all the scheming I did about overclocking ended up being very unnecessary and I found it borderline impossible to actually stress the upper limits of the machine's muscle with day to day workloads and so all the research I put into overclocking was not really practically necessary, that it was freeing to not have to even think about the machine and instead focus on the work I wanted to do with the software I was using and building. Surely a lesson that continues to pay dividends, albeit from simpler times...

by yowlingcat

12/31/2025 at 9:17:11 AM

Their Ultra series motherborads were legendary for the time. Namely AN7-Ultra for AthlonXP and AN8-Ultra for AMD64.

Besides being able to overclock anything to its absolute limits, they have repurposed a keyboard microcontroller to monitor temperatures, fans and voltages on the board (aka uGuru), providing unparalleled flexibility and reliability when no other company was able to provide at that time, and after them.

Setting fan curves for temperature response was great and allowed me to run AthlonXP at 2200Mhz (200x11@1T) without excessive noise for normal tasks.

Their AN8 Ultra provided a rock solid foundation for my AMD64 system, too.

None of my capacitors have leaked/bulged despite using systems under relatively heavy load.

by bayindirh

12/30/2025 at 11:08:36 PM

Brings back memories of late nights trying to reverse engineer the Abit uGuru chip. Triggered by not being able to read the sensors in Linux while trying to overclock my computer into being less of a shit computer. Reverse engineering was successful but the computer never got any better. Still, fun and educating times it was!

The thing that jumped out to me was the mention of the engineer jumping ship to DFI. Despite DFI still existing, they stopped making consumer stuff back in 2012, and it seems like they somehow disappeared from the consumer mindset even more than Abit did.

I recall that there was a while during the Athlon 64 era that DFI was the gaming board to get. But I feel like I hear references to Abit more often than DFI.

I think my old Opteron machine with a DFI board is kicking around somewhere still.

by whalesalad

The DFI LanParty UT Ultra-D (Socket A) is my favorite motherboard of all time. It was basically purpose built for overclocking. I got to a stable 250Mhz (500Mhz DDR) on that board and ran it stable like that for years, though I did put an active heatsink/cooler on the northbridge.

by freeAgent

12/30/2025 at 6:20:43 PM

Interesting read. I had the KR7A-133R motherboard as it won Anandtech's gold award for the best 4 bank DIMM support. It was $200 IIRC and was one the more expensive boards. Paired it with an Athlon XP 1800+ and Radeon 8500. Funny enough the AMD naming at the time was to reflect how Athlon's lower clock speed (1.5GHz) was a competitor to Intel CPU's (1.8GHz).

Asus was a strong competitor even then and I remember buying one just a few years before the Abit board that supported SD-RAM as well as DDR as a way to ease the transition for consumers.

It was a good time when IRC, AIM, and physical electronics shopping was still a thing. The only big tech presence that techies hated was Microsoft. Sigh.

> The Abit BP6 was legendary with enthusiasts because it let them make a dual CPU system with cheap Celeron CPUs.

And 2 celerons were cheaper than a CPU with double the performance?

by yjftsjthsd-h

12/30/2025 at 5:35:10 PM

Yes, because there weren't really CPUs then that had double the performance.

Celeron CPUs were usually CPUs that shared the same core architecture as the current Pentium standard, but often had a lower core clock speed, lower core memory speed, and/or had smaller L2 caches.

Workloads have different constraints however, and simply doubling cache, clock speed, or memory bandwidth doesn't necessarily double performance, especially when running more than one application at once. Keep in mind, this is Windows 98 /NT/2000 era here.

Symmetric multi-processing (SMP) could be of huge benefit however, far more than simple doubling any of the above factors. Running two threads at once was unheard of on the desktop. These were usually reserved for higher-binned parts, like full-fledged Pentium workstations and Xeons (usually the latter.) But Abit's board gave users a taste of that capability on a comparative budget. Were two cheaper than a single fast CPU? Probably not in all cases (depends on speeds). But Abit's board gave users an option in between a single fast Pentium and a orders of magnitude more professional workstation: A pair of cheaper CPUs for desktop SMP. And that was in reach of more people.

In short, two Celerons were probably more expensive than a single fast Pentium, but having SMP meant being able to run certain workloads faster or more workloads at once at a time when any other SMP system would have cost tons.

>Celeron CPUs were usually CPUs that shared the same core architecture as the current Pentium standard, but often had a lower core clock speed, lower core memory speed, and/or had smaller L2 caches.

This had an interesting side effect: Celerons of that era overclocked extremely well (stable 300 -> 500MHz+), due to the smaller and simpler on-die L2 cache relative to the Pentiums of the era, whose L2 cache was much larger but had to be off-die (and less amenable to overclocking) as a result.

An overclocked dual Celeron could easily outperform the highest-end Pentiums of the era on clock-sensitive, cache-insensitive applications, especially those designed to take advantage of parallelism.

by MontyCarloHall

12/30/2025 at 7:25:50 PM

IIRC Celeron cache being on die was actually faster as it was on die, this was mitigated on the Pentiums by there being more of it. It seemed like in games the faster cache performed better.

Another thing that helped the Celeron overclocking craze is Intel seemed to damage the brand badly out of the gate. The original Celerons had no cache at all, performed terribly and took a beating in PC reviews. So even though the A variants were much better this still had a stink on them.

The thing that probably helped the Celeron the most with overclocking though was they gimped them by only giving them a 66mhz front side bus speed. Since you had to increase this number to push the locked multiplier CPU speed up this was an advantage if you were going to overclock as you could buy a capable motherboard and run it at stable 100mhz. Whereas you'd have a lot more system wide problems trying to push a Pentium's 100mhz bus higher.

by garciasn

12/30/2025 at 6:56:23 PM

That was a bit of a two edged sword as the heavily overclocked Celerons would benchmark extremely well, but be somewhat disappointing in actual applications due to the lack of cache space. It was right at the start of the era where cache misses became the defining factor in real world performance. CPUs ran ahead of DRAM and it has never caught back up, even as per-core CPU performance plateaued.

by jandrese

12/30/2025 at 5:40:52 PM

Going from a single CPU to a dual CPU would, in theory, double performance _at best_. In other words, only under workloads that supported multithreading perfectly.

But in the real world, the perceived performance improvement was more than doubling. The responsiveness of your machine might seem 10 or 100x improved, because suddenly that blocking process is no longer blocking the new process you're trying to launch, or your user interface, or whatever.

Very interesting observation. Multicore systems have been fairly standard for the last 10+ years, and while you occasionally notice a misbehaving process hog an entire core, it never visibly impacts system performance because there are still several other idle cores, so you don't notice said "hogs."

It's much rarer to see misbehaving multithreaded processes hog all of the cores. Perhaps most processes are not robustly multithreaded, even in 2025. Or perhaps multithreading is a sufficiently complex engineering barrier that highly parallelized processes rarely misbehave, since they are developed to a higher standard.

100%. Its common for non-technical users to complain their laptop is faulty, because it gets hot and the battery drains very quickly. They have no concept of a runaway process in a hard loop causing this.

Except on Windows laptops. Where, although the computer is idle, your favourite svchost.exe will heat your system and trigger thermal trottling.

Just by the release MSRP:

2x Celeron 366 MHz @ $123 each - https://en.wikipedia.org/wiki/List_of_Intel_Celeron_processo...

1x Pentium III 733 MHz @ $776 - https://en.wikipedia.org/wiki/List_of_Intel_Pentium_III_proc...

And that's assuming that performance scales linearly with clock frequency (which it doesn't).

The Celeron 300A was the one most folks would go after for this. I don't recall the exact retail pricing at the time, but they were more or less guaranteed to overclock to 450mhz and be fully stable. Typically retail pricing could be had at discount to the published wholesale pricing within a couple months of release due to how quickly the market moved back then.

These were competing with PII processors in 1998, and for folks who wanted to go dual CPU it was the way to go.

There was a whole cottage industry of folks modding these CPUs as a small side hustle for people who were not comfortable with soldering onto CPU pins if you wanted to put these into a SMP system.

Performance really did mostly scale linearly with clock speed back then - but for a single CPU. The dual CPU setups were not nearly as efficient due to software not being as multi-threaded as it is today. The big win were folks with two monitors (rare!) who could run apps on their second monitor while playing games on the first. Typically you would only see frame-rate increases with CPU clock - and of course the very start of the serious 3D accelerator (3dfx, nvidia, ATI) scene back then.

It was certainly the golden age of enthusiast computing - especially for gaming.

When Intel switched from Slot 1 to Socket 370, there was a market for "slocket" adapters that allowed Slot 1 motherboards to take Socket 370 CPUs. The best of these adapters worked out a way to re-enable SMP on Celerons by tweaking the pin layout to disable the lock Intel had added. What made the BP6 so popular is that it was a native dual-slot Socket 370 motherboard that had this modification built in so it could use unmodified dual Celerons out of the box.

Even if you only had one monitor, multitasking was FAR better on a dual-CPU machine than on a single CPU system. For example, if you were extracting a ZIP file, one CPU would get pegged at 100% but the system was still responsive due to the second CPU not having any utilization. If you use a dual-Celeron BP6 system, it's a much nicer and more modern feeling experience than using a single-PII system even with the faster CPU with more cache.

Unfortunately you had to run Windows NT, which was a leap for most folks and had poor support for games and some other software written for Windows 9x (e.g. software that required DOS mode and wasn't compatible with NTVDM). Windows 2000 (Pro) was a bit more approachable, and then of course Windows XP (Pro) smoothed out most of the remaining wrinkles.

I ran Slackware on my BP6 while I was in college. Of course CONFIG_SMP wasn't set in the default kernel config at the time so you had to build your own. Great for running bind, apache, sendmail, etc., and of course NetQuake servers. :)

Yes but they got hard to find in a hurry once word spread. I had two 366s in my BP6 overclocked to 550 but IIRC I had to buy a few to find two that were stable at this frequency.

No modifications necessary with the BP6.

Ahh, the 300A and the BH6. Such a combo.

I bought two to have one gaming machine and one coding/hacking machine (including learning about networking now that I had two computers). Geek heaven.

Thanks for looking up the numbers!

That would be quite the "budget" SMP build. The 366MHz "Mendocino" was based on the prior Pentium II core I believe. So quite the disparity in single-threaded workloads.

The P3s often cost more than the MSRP at retail too back in the day, as they were supply constrained in period for various reasons, which heavily contributed to the popularity of BP6 builds with enthusiasts. Intel really struggled to ramp up P3 production.

For some reason you left off the part that explains that the Celeron had a PII core.

> Socket 370 era Celeron processors had a Pentium II core, but Intel disabled the ability to change the multiplier to discourage overclocking

by rconti

They may have sought to discourage overclocking by locking the multiplier, but...

People pretty routinely nearly doubled the clocks on Celeron 300As, anyway. :)

The legend was that Celeron 300A CPUs packaged in Malaysia were more overclockable than those packaged in Costa Rica. I specifically hunted down a Malaysian one, and it happily ran at 450 MHz for years.

by vasac

12/30/2025 at 6:28:50 PM

I remember that as well. The details elude me, but I seem to recall my 300A was running at 464.25mhz on an ABit B7.

by rconti

12/30/2025 at 5:55:15 PM

Not "for some reason"; I didn't see it as relevant. If anything, it being a PII-lite with overclocking disabled makes it seem like a worse option? What am I missing here?

> What am I missing here?

The whole point, really. Sorry, but you are.

In the Pentium / PII era, CPU speed was the product of 2 factors: front side bus speed and clock multiplier.

The original P5 and the 2nd gen P54 ran at FSB speed: 60 MHz or 66 MHz.

The later Pentiums ran at an integer multiple:

Pentium 120 = 60 MHz * 2 P 133 = 66 * 2

The PII ran at larger multipliers. I bought a PII 450 MHz on a Gigabyte motherboard that fit in my Baby-AT case, rather than the then-common ATX case.

450 = 100 MHz FSB * 4.5

That cost.

Slower PIIs had a much slower 66 MHz FSB.

PII 300 = 66 * 4.5

The Celeron had a locked multiplier but you could change the FSB.

So, take a 300 MHz chip (running at a locked 4.5x the FSB) but put it on a much faster 100 MHz FSB at the same multiplier and you got a 450 MHz chip, and because it had a much smaller but on-die L2 cache, it was more likely to be stable.

These Celerons came on a Slot 1 convertor and that needed to be modified to enable SMP operation.

Pics:

The famous BP6 motherboard ignored that setting and forced the uniprocessor-only Celeron to run in dual processor and overclocked it as well.

So for 2 budget sub-£150 CPUs, rated for 300 MHz on a sluggish 66MHz FSB and one CPU only, you got a dual-processor 100MHz FSB machine with the raw single-core performance of something like a £500 processor.

I never had one but you bet I heard about them and strongly considered it.

by lproven

12/30/2025 at 11:58:29 PM

IIRC even with a locked multiplier you could overclock the CPU by increasing the base (fsb) frequency. So you would change the fsb freq from 66 to 100 MHz and this way get a 450 MHz CPU from a 300MHz one.

by tpm

12/30/2025 at 6:34:40 PM

On the Slot 1 version of that processor you could disable the multiplier lock by cutting one of the pins on the slot.

What CPU had double the performance of a (top-of-the-line) PII CPU at the time?

by rconti

12/30/2025 at 7:30:30 PM

And then they left the overclocking back door wide open by giving the celerons a 66mhz FSB.

by deltoidmaximus

12/30/2025 at 5:22:23 PM

You could over-clock the Celeron and get even more performance. Both the slot-1 and ZIF style...

by SirFatty

12/30/2025 at 5:23:19 PM

they may have been, yes. back in those days, a CPU with multiple cores were meant for the server or enterprise workstation market and priced accordingly.

Celerons were consumer-grade budget kit.

by riffic

There were zero multi-core x86 CPUs, server or otherwise, back in those days.

Anyone in PC building during that era knew about Abit. Not really niche for a technical audience, but definitely nostalgic in a way that won’t make sense to anyone who wasn’t into PCs during that era.

by Aurornis

Big disagree. ABIT were the kings of build-your-own-PC in the 90's up through the early 2000's

Right, so how is that different than what I said?

How is a small motherboard manufacturer 25 years after minor popularity in a sub-community not niche of niche?

by SV_BubbleTime

12/31/2025 at 2:24:26 AM

Hard disagree.

Hacker news is IMO a niche community anyway, and I'd say the crossover between people who built their own PCs 25 years ago, during the golden years of overclocking and hacker news readers is pretty huge actually.

If you don't think this sort of article is a good fit here I don't think you are really in the target demographic anyway.
