I'm sure this has been posted before, but just curious, anyone have any old overclocked pentium 1s?

I've got a 166MMX running at 200 with passive cooling on some old IBM machine my neighbor gave me.... OOHHHH ;)

Looky at my sig :)

The 200 is running at 3 X 100FSB! and stays pretty cool with the stock HSF off the K6-2 550.

Also the 166 is at 180, its on an intel chipset board and it doesn;t like to overclock, but I'm sure the chip itself would do 200 anyway.

I've got a P-90 that is stable at 100 and runs nearly perfect at 133 (Prime can find errors... but then again, it DOES have that FPU bug some older P1s had :rolleyes:), and a P-100 also at 133.

Just got a new pentium system from my grandpa also, and have yet to find out even what speed it is, so I can't say how far it'll OC. Wish I knew how to bypass Acer's boot logo...

I have a dual 166 at 180

they are not MMX, but I guess they could do 200 just fine, they both have socket A heatsinks (AMD heatsinks) and since they're in pairs, the errors are more likely to show up ... I guess

what kind of cooling do you have on that 200mmx ?

I have a 200mmx too, but the fan is glued on the cpu, so oc'ing is worthless ... also it's my network server, should not crash, it has 200 days of uptime

btw, I tried to overclock my k6-2 350 to anything equal or over 351, even with a copper heatsink with delta fan, and artic silver (good conditions you know) with max voltage, I can't get a single mhz out of it. I'm using pc100 sdram, and tried a 105ish bus. But it doesn't beat the cyrix pr333+ I had, it couldn't even do default speed with default voltage, had to increase the voltage a tad lol

This chip sucks for oc'ing

It has the stock HSF off my K6-2+ 550... which is quite a hefty HSF for its day, pretty much the same as a TT Volcano 3, just very slightly smaller.

The K6-2's are not great OC'ers anyway, both of mine are OC'ed via the multi, not the FSB. From experience hardly any S7 mobo's like FSB more than 100, although the 450 is on a Soyo 5SSM which will run 133 FSB fine. The 550 is on an Aopen AX59 PRO.

I had my p1 up to 400 for a munute or two. :eek: with the stock hs/fan. :eek::eek: yeah, i couldn't touch it after it beeped and died. Too hot.

kinda hard to believe, I haven't seen a cpu capable of yet just booting with the double of his stock speed with normal cooling (normal = air or water, no nitrogen or something like that)

but if you tell me you did it .... what fsb mutl and voltage you used ?

I took my 200mmx to 233mmx. Fear my l33t skeelz.

I also took my amd k62 350 to 500 with stock heatsink. I dont know what people are saying that it doesnt overclock well. I didnt fsb overclock, but a 3/7ths overclock is damn good in my book FSB or not.

75mhz x 5.0 multi, 375 actually. :D like i said, it worked for a minute-not long enough to boot mind you-then died, so, technically, i guess i didn't "successfully" oc my p1, but it half booted and was a lot of fun. :p
