This old Intel Celeron processor was AMAZING

OMG I SOLD ALL THIS stuff i used to order them cases new :D lol crazy i sold over 10k pcs donated sold fixed

I remember mine celeron 300MHz to 450 on really cheap board. It was incredible. Especially in times one year old computer was already old...

My friends and I found that installing Windows while the CPU was overclocked made the whole system unstable. Never figured out why, so we just made sure to have everything stock in the event we needed to do a clean install

Had one of these i over clocked to from 300mhz to 660mhz never will forget that

i had a coppermine based celeron 533 that i ran for years at a min 850mhz. but could run it over 1ghz but wasnt stable in the summer when it was hot in my old place. temp monitoring software capped out at 100c core ;) so i have no idea actual temps. that was with a decent cooler, and voltage upped.

2 seconds in, i can see the b21 pin. i know whats going on ;)

I bought my 300A in Decmber 1998. It ran with 450 MHz. The secret was, they took a Server CPU. Mendocino? That was also my last Intel CPU. After that I switched to Athlon 1 GHz. AMD had the first 64-Bit CPU and the first Two Core CPU. Now I have a Ryzen 16 Core 5950X.

dual celeron 366s @ 550 on air up to 917 on vodka and liquid nitrogen abit bp6 lets gooooooooooooo

Period Correct is nice but that thing is begging for an SSD.

Voodoo 2 3DFX card was pretty good then. It only did 16 bit, but it did it really well

I thought you needed to slightly increase the voltage, and try to cool it with a better fan

Man's flexing the trinitron with the OC'd PC like a period correct baus lol

Had a 300A running at 464 Mhz. It was a beast. Comparable to many P3 processors back then.

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.

I had that chip back in the day overclocked to 450mhz. Good times. I had it on a Pentium 100mhz board. There was a riser board sold to make it all work.

Love the Yamaha XG. I've got 5 of them.

I remember overclocking my old celeron from 266mhz to 500mhz on some Asus board (BX66). Good old times.

I remember this well, although I never owned one. I did eventually upgrade my work PC with a 1.1-1.2 GHz “Tialatin” CPU, just over $100. The latency of these CPUs was the key to their performance.

I had a dual 300a system - abit bp6 motherboard, with golden orbs and a modded case with fans placed on the side, I settled on 450 mhz on both cpus, and I had mad fps in quake, which supported dual cpus, it was pretty fun at lan parties, it was a surprise to many, how insane those cpus were.

a journey to youth... The next step was Duron 600@933...

I cant remember which model, But I remember there were some wonderful celerons and some really shitty ones too.

Stil remember my disdain for Celerons. This brings me back to highschool at the trade school where I was taking Cisco and Ares+.
Ill never forget that pentium 3 1500mhz cpu and the premium it was. It was a leap in speed from a the old slot cpus. I see now they never went back either.

Never used floppy drives long enough for one to break and actually kill floppies, was that common? Or is that common now that the older stock and plastics are degrading and such? Just figure something must have really gone wrong for it to destroy the floppies media.

me and a fried owned a computer store in high school, we bought an entire tray of OEM processors for the PC's we sold. we cherry picked the highest yield celerons for our own rigs and actually cooled them with a peltier and large heatsink. we probably had the highest performing PC's in our small town. the celeron was awesome in this era.

I had the 300A overclocked to 450MHz. I’m pretty sure I had an AOpen mobo that wasn’t as overclock-friendly as Abit, but i had a good Malaysian made CPU and with the case cover off and a big desk fan blowing on the mobo (even in Summer in a rental apartment with no air con) I got stable overclocks playing Half-life and Commandos. Hitting that 100MHz bus was the holy grail. It was the only time in my life I’ve done overclocking as I prefer stability over benchmark flexing, but man for the price and performance at the time, it was so worth it!

Costarica Made's was the Best for OC theses days

I built several Abit dual Celeron systems for 3D rendering decades ago.

The extra Mhz on the P2 was worth too much to pass up when pairing it with the Voodoo Banshee. 😁

I had a celeron a on a Abit motherbord

PLEASE PLEASE This Does Not Compute WHERE DID U GET THAT CASE! I WANT IT!!!!!

intel celeron was giood if u cant spelkl amd

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.

imagine building a PC today, using the budget back then?

im escued main bord end this cpu , insaide pcb vibra 16 opl yamaha music card isa , pci grafics s3 trio , cpu CELERON , 333/66, sl2nwn /main board asus p2e-M ,. works but celeron ehhhhh ,. NOT GOOD CPU ,.werry slow , werry heat 80 c , why ??? ,. cpu cooler works prfect ,

Celeron its a cpu only for office not to gaming , not for multimedia mathematic , or core its works slow , im tested 98 pentium 2 end this celeron verdict scarred for celeron , celeron its a cut processor from penium 2 or 3 , to day intel pruduced celeron-s cpu , but good only office this cpu ,

Ah, the Intel Celeron. We used to call them Celery processors because at one point they were severely disabled (like a vegetable) Pentium III that Intel recycled. I think there was a batch or version that had poor yields so that's why they gave them the lobotomy. That said, for general computing they were probably fine. At that time AMD was releasing the Athlon series of processors and had relatively positive success with its 32-bit Athlon XP that was then followed up, as you know, with the Athlon64, X2 and similar systems that mopped the floor with Intel until the Core iX series was released.

I used epoxy on the pins to OC my 300A. Ran that PC for years. First 3rd party CPU cooler I ever bought.

God this makes me feel old. We were so amazed by dual speed cdrom drives, 90 MHz processors
... and good lord, going to a full 16MB of RAM was a gamechanger 😂

im curious how these things would do on todays hardware, pcie lanes 32gb ddr4 system😂

woot 54x 😂❤

I had one, it overclocked like nothing else at the time and it did so without a problem..
You just needed a good motherboard and memory
we never taped off any contacts on the cpu.. ever.. not needed

We used the then rather new MSI on micro ATX formfactor, great boards with acreative labs audio chipset on the mobo, also a first.
the onboard L2 cache wasn't at all useful for gaming so you never noticed it missing in gaming if you had a full P2 vs an overclocked Celeron side by side on equal motherboard , memory and video card..


I built and sold hundreds of these , it was the first widespread overclocking cpu in existance.

those Yamaha sound cards were HORRIBLE for dos compatibility sucked balls.
That you can play a MIDI file properly on a YAMAHA OPL chipset is no surprise, all soundcards used YAMAHA OPL in those days
The thing you needed was Windows and DOS Soundblaster compatibility which only the Creative Labs did right, with ESS sound drive a close second. Yamaha on the other hand sucked balls

The Riva TNT did not deliver either at the time.. S3 Trio and later S3Virge + 3DFX was the name of the game for dos game compatibility

PSU's were not an issue at the time, they all delivered plenty , they were bult reliable and I would not have any doubt about what you call a sketchy PSU.. that is just laughable ignorance on your behalf..if it has voltage, its good.

Your disk detection fault is YOUR fault!!
you put the HDD on Primary ATA as primary
the CDRom goes on the secondary ATA..

That way they don't get in eachtohers way
AND the slow cdrom does not slow down the fast disk (ATA cannot share the bus at the same time!!)
AND you can copy full speed from secondary ATA controller's cdrom to the primary controller's disk

Honorable mention: Celeron E1200 Dual Core which was an absolute effing beast OC'er had mine running 3.6Ghz up from the stock 1.6Ghz on a Gigabyte P35 board
That's an insane 125% OC(compared to ~66% for the C300A@500mhz),and it ran rock solid with no issues for the better part of 4 years, absolute killed any incentive to upgrade 😂
After that, locked multipliers became the next big thing

P.S. It's an even more massive boost than expected since the FSB was running at an almost 100% OC too. 😏

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.

Nostlagia shot. Thanks dude.
I've had Abit BP6 with 2 Celerons 400Mhz with Golden Orb coolers. Nice time.

i used to have a dual processors
300a overclock to 500 best machine evere

Anyone recall the dual socket mobo, the abit bp6 designed to take advantage of these amazingly celerons?
