Has anybody attempted to oc an old pentium or mmx? tell us about it.

[EvilDonnyboy]

I'm curious, though I doubt my old pentium 200 will do 233 because it's the fastest in it's line of cpus, and well, its a pentium.

i did. look on your mobo. if you're lucky there are multiplier adjustments. just choose the highest multiplier for 233 mhz.

 

[EvilDonnyboy]

my 200 is already runnin hot with the retail (I think) hsf.

I already know my mobo supports a 233, but I'm worried how my 200 would react. The 200 is still being put to good use in my second computer. It allows other people to not bother me while I'm gamin when they want to play solitare or type and print stuff.

Anybody else wanna share results?

 

[403Forbidden]

it's great to play solatair on a oc'd cpu

 

[they call mr big]

get a k6-2 mothboard and you might be to overclock to 300 mhz seen it before

I once had a Gateway P5-120 that I oc to 166, with multiplier and FSB adjustments.

The mmx version of cpu (166 - 233) overclock really easily. I have my 166mmx @ 200mmx (would of gone higher but my motherboard didn't support it) for over a year now. I have seen the 166 mmx as high as 297 (4.5 multiplier). You should have no problems running your 200 @ 233. Just make sure you have thermal grease between your cpu and your HSF. I'm using a standard heatsink and fan on mine and it stays on 24/7 as my Linux box.

The Pentium mmx series of chips do run a little hot, so don't be alarmed.

I used to have 233 cyrix before this comp....did 266 quite easy but the multipliers didn't support anything higher.
I didn't notice any improvment anyway, it's not really worth the extra heat.

I overclocked my roommates old P200C. The max speed the motherboard would support was 225. Worked like a charm though.

The Pentium MMX are good overclockers. I overclocked my P166MMX on a FIC VA-503+ to 250MHz with no problem. That's a 50% increase!

Hmmm.. I had a P-120, wouldn't even do 133. I never tried sanding it. Instead, I sold the cpu, mb, memory on e**bay for something like $50. Good luck to you though.

I have a P166mmx lying around that will do 200 or 233 just fine.

 

[Lark888]

166MMx running 233MMx without any problems. Would likely go higher but the IBM Aptiva doesn't give me any higher multipliers.

 

[theanimala]

My main (and only) home system runs is a P120 that I run at 133mhz. I see no difference in performance at all, but what the hell?

 

[eia430]

I had an old P200mmx that I had overclocked to 292mhz... on a shuttle 565 motherboard with an AOC k-6 heatsink. It ran totaly stable and was faster than (not by much) than a friend's sony vaio PII 266. Hope this helped..

I once overclocked a P200MMX to about 374Mhz. It was on a Kobian motherboard based on the super socket 7 architecture using a VIA chipset. The multiplier was 4.5 and the bus speed was 83 Mhz. I used water cooling without a peltier. I couldn't go any higher. That was the limitation on the motherboard.
