This old Intel Celeron processor was AMAZING

[@borismatesin]

Former Celeron 333A owner here, I remember doing the B21 taping trick on an Abit BH6 motherboard. Went from 333 MHz to 500 MHz, didn't generate any significant extra heat, and the speed boost was immense. The computer's horsepower basically doubled with that (and going from 32 MB PC100 RAM to 128 MB PC100 RAM doubled it again).

[@Sicarius888]

Nice. My 300A could do 433MHz. Tech magazines claimed 450, by my crashed.

@@borismatesin I was still very happy with it, good price to performance ratio. Soon after with tape trick becoming more known, prices went up quickly.

It's always amazing to me to see hardware that I used to buy as a teen in the late 90s in videos like this. The no-brand gold motherboards, the generic sound cards with the Yamaha chipset, and the cheapest CD-ROM and floppy drives I could get my hands on. The cheap CD-ROM drives taught me about spending a bit more to get something far superior as some of the cheap drives would freak out over disc errors and start spinning the disc as fast as the motor could go, which the magnetic clamp wasn't designed to handle, so your precious CD was launched into the nether regions of the drive getting scratched to hell. It was a wonderful time to learn and explore computing.

[@volvo09]

Yep, that was like my build at the time, all the cheap stuff out of the computer parts catalog (except I was socket 7). It was a fun time in computers for me. From building my first computer at age 12 or 13, slowly upgrading it, and eventually getting a modem and being able to go online.... There was so much change. I had a hand me down monitor that could only do 640x480@60hz and lived with that for a while till i replaced it.

If I remember it right, the 300A made in Malaysia was easier to overclock than those made in Costa rica Mine did 450 without any voltage mod but was unstable at any higher speeds or mods, my friend got his to 504Mhz with a little more voltage and improved cooling. Later on in the run when the 300A disappeared the Celeron 366 and 400 was good options, a bit too high of multiplier but they could reach good speeds with the right motherboard that allowed more granular bus speeds. I still have all that stuff in my attic. BH6 motherboards and all. I have the past 40 years of computing up there, never got rid of it. Perhaps I should start a channel going through it all. 🙂

[@christineclips]

The 100 mhz bus speed was very important to overclocking because the BX chipset had a 2/3 divider for AGP and 1/4 for PCI. The 75 and 83mhz frequencies meant you couldn't have a proper divider for the appropriate bus so either you were underclocking or overclocking all your PCI and AGP devices. From what I recall 3DFX cards had issues with the 83mhz bus. Despite the reduced cache, the 300A at 450 would outperform the P2 450 in some benchmarks because of the full speed cache, which was just embarrassing for Intel. Fun times!

[@DCLXV2]

Almost all benchmarks

[@horstlederhosen]

Almost true. :) If you were willing to solder few jumper wires you could feed at least to AGP, which usually was bigger problem than PCI, lower frequency. One could probably still find some of ancient forum posts I wrote back in the day on how to do this with Asus slot-1 motherboards. Resistor to lift and feed lower frequency was between AGP slot and 440BX chipset and very easy to access. Going higher than 133 MHz FSB was still challenge, I think around 140 was max even on boards that has clock chip capable of generating slightly above that. Getting that high frequencies from clock chip of course required more soldering.

[@HappyBeezerStudios]

Running 112 FSB (for 504 MHz on a 300A) would put the PCI at 37.33 MHz (with 1/4) which isn't too much, but AGP at 74.67 (with 2/3) or 84 MHz (with 3/4). Not all cards can do that, some slightly later Geforce will run fine even at 89 MHz (in case you want 133 FSB for a newer Pentium 3) i815 does a bit better, I can run my Coppermine 933 at 1071 with 153 FSB just fine, but I stop at 148 FSB because beyond that I need to drop my memory from 1/1 to 4/3 and that costs me more performance that the bit more CPU gives me.

The Celeron 300 was a BEAST! During that era I built 5 gaming systems for family and friends, ALL of them where Celerons. Local stores helped out, binning the Celeron chips for a $25 charge. This mean we KNEW the chip we bought was going to clock to 450Mhz with no issues. It was an incredible chip for the time.

[@AnonymousFreakYT]

A bit of history: For the original Pentium and Pentium MMX processors, the CPU was in a socket with just the CPU on it, and any L2 cache was on the motherboard in a separate cache slot or in later ones soldered to the motherboard, that operated at best at the front side bus of the processor. Pentium Pro became a gigantic socketed CPU, because it had not just the CPU core on the processor circuit board, but also the L2 cache - running at the full speed of the CPU, not the front side bus speed. This is one reason the PPro ended up so much faster. Then came Pentium II, which was basically just "Pentium Pro MMX" in a different package, moving to the cartridge-like "Slot" system. One of the ways Pentium II became the "consumer" model was by cheapening the cache. Instead of cache running at full CPU speed, it used commodity cache chips further from the CPU on the CPU card, running at 1/2 CPU speed. (Much better than "front side bus speed" of the Socket 7 systems, though. (Of note - the "Pentium II Xeon" in the absolutely ginormous "Slot 2" package returned to "full CPU speed" L2 cache.) The very first Celerons were literally just the Pentium II core with no cache. Intel called it a different name (Covington instead of Deschutes) but it was the exact same core, just with a fused connection to tell it not to even try to use L2 cache. The 300A was the amazing change - 128KB of L2 cache - inside the CPU itself. Same piece of silicon as the CPU core, not even "separate chips on the same package" like Pentium Pro. The first consumer CPU to have so much cache onboard. It was still at the actual CPU _core_ level still a Deschutes Pentium II core, with the added cache. The main reason the CPUs could overclock so well was because by the time the Celeron 300A came out, Intel had firmly "solved" the core speeds. Most of the Deschutes Pentium IIs could actually handle 450 MHz no problem, most of the 400 MHz were just downclocked not because they had to be, but to sell the cheaper model. That meant that the Mendocino Celerons based on the same core generally had no problem going much faster. The same basic Mendocino core was officially released at up to 533 MHz. One of the reasons an overclocked 300A at 450 MHz did so well compared to a "full fat" Pentium II 450 MHz was that cache difference. Sure, then Pentium II had 512K of cache, but it was running at 1/2 speed. The Celeron may have only had 128K, but it was running at full speed. At the time, many applications were just fine with 128K of cache, so that faster cache was better than more-slower.

[@HappyBeezerStudios]

Ah, the age old method of selling a chip slower to meet market demand. The sheer amount of Northwood 1.8C that would do 2.4 without issue. Or all the slow clocking Core 2 chips that also went into the same 3.2-3.8 GHz range as the fast ones. And the dual core Athlons that could be unlocked into Phenom quads with a juicy 30% clock bump on top.

We had a computer lab I. Middle school full of Celeron 300A and 333A that we were able to overcook to 400 and 450 MHz. Our computer teacher instructed us on how to do it. He had two genuine pentium II towers that he used for his computer and the classroom file server and our over clocked systems kept up with them.

No, it was fun. I always overclocked Intel CPU's to see what they could do. The 'Celery' was a favourite. AMD chips had to be treated carefully, to keep them cool, but they could be pushed if you had the right MB. Even earlier, when 486 was in vogue, Cyrix CPU's could be pushed to run faster than any Intel one with the same nominal clock speed. The 120 MHz chips could usually do 160 MHz and some went much faster. I had a Cyrix CPU running at 247 MHz for a year or two, with a bigger heatsink and a good blower. It was faster than some of the early Pentiums.

Mhm falling a little short of P2 for sure. Faster cache is helpful, but not helpful enough to completely offset the penalty from having a quarter of the cache. Rule of thumb, doubling of cache gains 7% performance.

[@HappyBeezerStudios]

@@SianaGearz it's a bit of cache size vs cache speed. If something makes use of >128k then yes, the P3 was noticeably faster. but if it works fine with the small cache, the Celeron runs ahead. All depends a bit on the task. I remember some tests during the core 2 era, where going from 512k to 1M gave about 15-20% and going to 2M gave about 20-30% in actual games. But there are diminishing returns. In the same test, going from 3M to 6M gave only about 5-10%

Celeron 366 owner here. Bought the MSI bx440 mobo and cpu from NCIX guarenteed to overclock to 550 mhz. This was such an exciting period of time.... Every 6 months was a leap ahead, and hardware from a year ago was obsolete (i use a 10 year old computer now adays) .. Online gaming technical challenges were overcome (gamespy and good netcode) and reaching a golden age (counterstrike,starcraft,everquest). What a weird time go grow up: as i thought this rate of change was normal.

[@DCLXV2]

Regarding the PSU covering part of the motherboard - that's just a design consideration, you can either mount it transversal above (or below) the motherboard or you can mount it longitudinal "beside" the motherboard covering it for a lower height but thicker case

[@ryanreedgibson]

I was 8 when I last built a system like this. The ribbon cables bring back memories of trying to troubleshoot why my hard drive didn't work. I had the wrong master jumper selected.

[@ninkeon58]

What you were seeing with the memory density on your motherboard is actually very common across all 440BX era boards, as they had trouble addressing high density memory modules. I've ran into this quite a few times even on my higher end MSI motherboard. The next evolution of Intel chipsets, the i810/815 resolved this issue to my knowledge BUT those were limited to only 512MB memory at maximum, rather than the potential 1GB on 440BX boards. The best way to get around this limitation was to acquire double-sided memory modules rather than the later single-sided SDRAM modules used by low-end boards from the P4 and Athlon XP era.

[@HappyBeezerStudios]

The i815 has another interesting memory limitation. It only supports 4 ranks, but most boards have 3 slots. So depending on how your sticks are set up, you might not be able to run a pair of 256M sticks or a 256M and a pair of 128M together.

[@spliffen]

remember having the 300a at 450hz, and how I remember it, was, you talked about taping on the connections to get a higher frontside bus, I remember taping the connections to get a higher voltage... maybe try that

[@SeaJay_Oceans]

I'm bookmarking this as a perfect PC build & story video. Excellent production ! Thanks ! 🙂

[@brmolnar]

Testing my memory - around 1999/2000 there was a way to put 2 Celeron's on certain motherboards and get some impressive performance for the price. There was even a way to rackmount the whole setup and run Celerons in your servers. I forget most of the details and the old website I used to use is not in the internet archive.

[@somerandomguyfromthestreet464]

16:10 One of the traces in the top left corner is burnt.

[@mausmalone]

Ah this takes me back to the early 2000s when I was actually building PCs. Specifically, buying budget parts and then having to buy them again because they were either DOA or incompatible.

[@kimvette1]

The best was the celeries you could run in an SMP configuration on the Abit BP6 motherboard - yes, a dual socket, dual-processor celeron system. I had installed them with peltier junctions(the best we could do - we didn't have appropriate cooling blocks for liquid cooling) to assist with cooling for some massive ( by that day's standards) overclocking.

[@DaivG]

I love that you hit just about every SNAFU I hit building and upgrading computers in that time period.

[@qoncept]

My first computer build was a Celeron 300A overclocked. Even wrote a paper on the research I did to make the decision for one of my classes at the time. It kept running after I broke the backplate of the heatsink and replaced it with MDF and wood screws.

[@jarthurs]

Serious flashbacks for that PC case, I had that one for years and it ran a Pentium II 233MHz as a home server for a good part of that time.

[@andrewi76]

I went one step further and bought 2 of the flip chip BGA variants, a couple of slot-1 converters and a dual slot motherboard. After soldering the bus arbitration pin from the socket to the edge connected. I had a dual 300A system running at 450mhz. A true beast. Triple booted into windows 2000, Linux and BeOS.

[@null0byte]

I don’t remember what motherboard it was, but I had a 300a and simply putting in PC100 RAM it ended up overclocking itself to 450MHz (due to the multiplier with the faster front side bus). Loved it. I got mine in the Socket 370 version, but my board was a slot 1 board. To get it to work, an adapter called a “Slocket” was used, which was basically a socket 370 on a daughterboard with a slot 1 edge connector. You even used socket 370 coolers on it. The first Xeon processors also came out about this time and were absolutely massive things. Basically a really tall Pentium II to make room for the extra cache chips running at full speed.

[@alexisrivera200xable]

Thanks for the nostalgia trip! I worked building computers back then and built many systems with similar specs. from what I can see the memory and the replacement optical drive was the only real thing you went with that was more than usual. Great video! You were correct. That board would not let you push power too much. The cheaper boards would trigger power protections at relatively low thresholds or straight up give up the magic smoke. The power delivery circuitry was much better on the higher end boards.

[@tophermctoperton7819]

The Celeron 300a was a beast because the 128k Cache was on the cpu die, not on the slot-1 pcb at 1/2 clock divider. At that time, coding was still very tight and little if anything would fall out of the l2 on-die cache and hit the ram. If it stayed in that magic full speed 128k on-die cache it ran better by small margins due to lower access latency .. i loved my 300a .. simply an amazing cpu.

[@The_Nametag]

I had a Celeron 300A. Overclocked to 450, on the Abit BH-6. The overclocker wombo combo. Incredibly stable, cooling on them was honestly easy (especially compared to today). It was a dream. I That system served as a primary gaming rig for many years, didn't replace it until 2004 when I upgraded to run Doom 3. Even remember having an Nvidia TNT card, followed by an original GeForce. Good times. I kept the system going for years after that as a secondary, and did eventually have to bring it back down to 300, but that system was a rock.

[@sergkot3462]

My first pc was on celeron 300, good old times ;( And my father bought me it because in some pc magazine there was an article, how to overclock it :) because there was no interner at my location in that time

[@videofrat3115]

I had a celeron 300 overclocked to 450mhz. Back in the day it was a beast. 50% overclock. I remember i had a desk fan pointing at the case (with the case lid removed) to prevent it from overheating. Had a Voodoo Banshee on it too. Worked great.

[@tlhIngan]

I made a PC and bought a Celeron 533A (Tulatin) back when they were new and it overclocked nicely to 800MHz with only a 50mV increase in voltage. Which was less the CPU and more a motherboard thing as even non-overclocked it crashed randomly. But give it 50mV more (it was like 1.80 to 1.85V) made it rock solid. That too was a major overclock, and it too had half the cache of the Pentium III of the era (the 533A was based on a Pentium III core).

[@Nukle0n]

I'm kinda late here but some of the traces on the CPU at 16:16 look a little odd under the solder mask, specifically the 3rd pin from the top. At 11:36 some of them also look odd with oxidation running down some of the pins, including the one with tape? Just wondering if maybe that leads to the system being less stable at higher clocks if there's higher resistance on those contacts.

[@tomtom98]

It looks like your first Celeron 300A has multiple burnt traces / corroded pins. Or am I going crazy?

[@michvod]

Those sticks of 128MB RAM also look crusty. Pins are very darkened and have oxidized.

[@SianaGearz]

Looks like pads carrying VCC Core rail show discolouration on the CPU daughterboard. It may have been continuously overvolted in the past.

[@songsan807]

I remembered building PCs to sell at eBay and as a computer technician at a computer retailer around this time. These Celerons were very popular. Crazy thing was that you could do the overclocking with the Cyrix chips that were clocked at 50Mhz and use Amptron or other motherboards that have 66Mhz and 75Mhz to bump up the speed depending on the chip from 150Mhz to 225Mhz. Or 200Mhz to 350Mhz depending on the chip. Did noticed a big difference from 150Mhz to 225Mhz when playing a snes emulator running Super Punch Out that time. Golden era.

[@HappyBeezerStudios]

with zsnes I assume?

[@neversleepy]

Your issue with the Hard disk, and why the SD adapter worked - may be the CD-ROM was moved to master on the Secondary IDE port (based on the video's timeline). It was always recommended to separate HDD from CD-ROM in these systems.

[@joshwilliams6482]

My first build was a 300A overclocked to 450mHz. I can't remember the total cost, but it was less than half the price of a pre-built Pentium II 450. The shop I ordered my parts through was so impressed with the results they started building 450mHz units using the 300A, but they tried to pass them off as Pentiums and ended up getting sued out of existence. I kept that computer for a long time, with a final CPU upgrade to 1400mHz using a slot1 riser with a Pentium III.

[@michaelturner2806]

Worth noting that with simple utilities released by hard drive makers, you could get around the large hard drive thing. Just set the bios to anything manual, boot the utility floppy, and it would install something into the hard drive's MBR that would override BIOS calls and let it use the full size. The caveat was you couldn't boot directly from any boot disks afterwards and see the drive, so most had a little pause or indicator to push or hold down a key during hard drive boot to then boot from floppy. The Western Digital one wasn't hardware locked and could be used on any large drive. Also (if you didn't just cut it for relevancy/time) be sure to install motherboard chipset drivers and double check to make sure the drive is operating in DMA mode. It could make a difference for AGP video performance as well.

[@kFY514]

I had a Pentium II system back in the day and had a similar problem when wanting to upgrade from a 5 GB disk to a 40 GB one. What fixed it for me was a simple BIOS update.

[@Saturn49YT]

I ran a 300A at 450Mhz for half a dozen years. It was super stable. I remember having to put kapton tape over a pin or two, which may have bumped the voltage up slightly?

[@ryelor123]

I know some video I saw on here that was talking about old electronics mentioned that you need to 'reform' the capacitors or replace them since over time they quit working and can burn out electronics. That's what I think is happening here with some of your equipment.

[@DM-20XX]

Had the 450 Mhz one and was really a gaming, emulation, and media editing BEAST for the price in that era. Used it even for a good part of the Windows XP era.

[@zakknettin]

flood of memories. I had a similar setup back then. Overclocking felt almost illegal

[@LeoLijo]

You can get larger capacity drives working by setting a capacity limit jumper on those drives, it limits the drives capacity to 32gb but the motherboard will detect it, that allowed me to use a 40gb ide drive with a 440bx board. It was just a limitation of the bios at the time.

[@Lemurion287]

I was one of the few who ended up overclocking on a VIA chipset before I got a 440BX motherboard. The overall performance wasn't as good but the overclocking potential was insane. My 300A had the shrouded cooler on it, not the one in the video and it ran like lightning. If I was willing to accept occasional crashes, I could reliably get 540MHz out of it, and 504 was pretty much rock solid.

[@Cybercharger]

Would be interesting to see you trying some voltage mods on these older boards! Great work on your channel!

[@Starfireaw11]

I had a pair of 300As clocked to 450 in a dual slot motherboard with a pair of voodoo2s. To get the processors to work in a dual system they had to be modified. I can't remember the exact process, but it involved drilling some holes in them and soldering a couple of jumper wires.

[@123cyr]

Another former 300A owner here, ran it at 450MHz paired with a Voodoo3 3000 card. Many hours spent playing Quake3 and Unreal Tournament over LAN with friends on the weekends...

[@raylopez99]

The Celeron 333A is so old I could not find a release date for it. The best I found was an article from around 1999 so I assume that was about it...and I see our narrator says October 1999.

[@37Kilo2]

Good example of Silicon Lottery. I miss building PCs back in those days. It was a lot of fun.

[@drcrsvideos5656]

good memories. The pentium 2 300 was my last computer with a massve gap inbetween till I built a Pentium 4 2,8 explicitly to play doom3. Totally skipped the P3 era but am now making up for it with an exploding in size collection, lol.

[@Martin_from_SC]

Brings back memories... my 300A ran happily at 504mhz @112mhz bus speed without voltage increase, of course on an Abit BH6 mobo... ran great for many years!

[@volvo09]

You were one of the ones I was envious of if you ever posted that speed on a forum! I could only get a stable 50mhz overclock out of my K6-2, 100 would crash in a few minutes.

[@Martin_from_SC]

@@volvo09 I also had a Celeron 600 running at 1200mhz@133fsb, though that took a big heatsink and voltage increase, these little chips were surely capable.

[@HappyBeezerStudios]

@@Martin_from_SC And then look at the Tualatin Celerons, picking a 1200 and clocking it to 1596 with 133 FSB was absolutely a thing. They could've easily released a 1600 Tualatin, perhaps even more. Even the existing 1400 had no trouble doing 1575 MHz with 150 FSB. The only real limitation was getting memory that could run higher. Some people managed to get over 1700 out of a Celeron 1400. The current WR under air is 1839 MHz. That 600 @ 1200 was absolutely golden.

[@ShaneGoodson]

I remember learning the joys of overclocking on the family computer's celeron.

[@fanatic26]

One of the first pre-built computers my parents bought me was an generic eMachine...that happened to have a Celery 300A in it. Saved up for an Abit board and I ran that chip at 450 mhz for years, long after it was my daily driver it ran slackware linux iptables-firewall (back before you could just buy an off the shelf router lol) I got a good 7+ years out of that chip before retiring it. As far as yours went, you just lost the silicon lottery. The reason the celeron 300A's OC'd so well is because they were actually p2 450 chips that couldnt pass QC so they got binned for the Celerons. Yours probably had more issues than most and it just wasnt in good enough shape to run at 450.

[@Jonny_O]

I seem to recall the Malaysia-packaged 300As were more tolerant of overclocking than those packaged in Costa Rica. Or was it the other way around? I can't remember anymore.

[@chinsta00]

You can adjust the voltage of the CPU by taping off pins, just like you did with B21. This "taping off" is more elegantly accomplished by using a socket 370 CPU in a slot 1 converter daughter board with jumpers for bus speed & voltage adjustment.

[@JohnAmanar]

Beautiful video! It made me tear up. I miss my childhood and the amazing LAN parties. I was rocking a Celeron 700MHz for many years.

[@belstar1128]

2:15 got to love that "cheap" 999$ just for the cpu

[@abooogeek]

If I remember well, it was a particular batch of Celery 300A that were making wonder in overclocking like the SL2WM one (according to archives on Anandtech) and I think 2-3 other ones of the SL2XY.

[@octofui]

My favorite part hack of all time is the athlon xp to mp conversion, getting a dual athlon mp machine was just amazing

This does not compute on a Saturday morning. Nothing gets better than this.

[@jasonk9779]

Did this with the Abit motherboard "back in the day". Worked great!

[@aaronscalise7682]

so cool, but failed to mention how the OEM versions didn't overclock as well as the retail box versions. i built many of these in these years.

[@KaldekBoch]

I owned a 300A and recall overclocking it. I don't remember how fast i managed to take it though, but i do seem to recall not winning the silicon lottery.

[@Kholaslittlespot1]

I miss this era, and the games that came with it. Not hung up on the latest and greatest, still playing old games like Myst and lucasarts titles as well as new stuff. If it was good it got the seal of approval. I love modern games, but there is something about this late 90s- early naughties era that brings back that warm fuzzy feeling. It makes me a tad emotional!

[@erickvond6825]

I actually had one of the Abit boards you mentioned. Those overclocked like a champ.

[@fixitman2174]

I still have my best overclocked PC. It has a Celeron 566 on an Asus socket 7 slotket, plugged into a Gigabyte GA-BX2000. It ran my Win2000 advanced server for years at 850 MHz. That PC was a beast back in the day.

[@MrZcar350]

I didn't build from scratch in that era, it was right in the middle of my time with Socket 7 where I did some upgrades (new Socket 7 CPU, etc.). I did a later cheap build with a Tulatin (IIRC) Celeron (with a mild OC, of course). IIRC, it was a GeForce 2 GPU, my second nVidia after a RivaTNT a few years earlier.

[@Menda_Lerenda]

I remember my Pentium 1 had a 40Gb hard drive with a jumper that limited it to 32Gb, I don't remember why exactly. By the way, you can boot directly from the windows cd, no need for the floppy since windows 95 and pentium.

[@2xtreem4u]

the jumper is labeled as cap limit on my 40gb maxtor hard disk
