stable overclock become unstable?

RaiderX · 27 Apr 2007 at 19:20

i have been running my PC non-stop for that last few days with no problems at 2.97GHz, when i first got it that high i run orthos for almost 9 hrs and it come out stable. ive been gaming and have had no problems.

today when i went to play counter strike as soon as i loaded into a map it would tunr the PC off and then back on.

any ideas to what could be the problem, it only does it when i run a 3D app.

Try clocking it down

I'd hazard a guess and say your memory is stretched slightly beyond its limits.

Power supply possibly.

Overheating.
Clean it out.

my guess too seeing as how most people just overclock the cpu and then run orthos to test the cpu and completly forget about the ram.

I was going more by his 2GB Crucial Value PC2-5300 running at 850mhz.

I'm not familiar with that memory, but it's a heck of an overclock for value RAM.

i run memtest with the overclock and it didnt find any errors, i also run orthos on both memory and CPU blend, and if anything is overheating its my PSU, memory is only slightly warm to touch under load, and CPU temps peak at 50 load, PSU is a cheap 600w i paid just under £10 for, the memory is http://www.overclockers.co.uk/showproduct.php?prodid=MY-084-CR&groupid=701&catid=8&subcat=144

I imagine it's due to lack of power, as soon as the GTS starts working your PSU can't supply enough power.

i do need a new PSU, my current one sometimes turns off randomly, even on my old mobo

Agreed. The hotter weather is making your PC overheat and with the build-up of dust it only gets worse.

Fool - go to Africa when it's raining and tell me it can't be hot and wet at the same time

Seriously, from what you're describing, I would try remounting the heatsink. It's your choice but we can only make suggestions; for the minimal time and effort involved it's at least worth ruling it out.
