16 hours prime95 stable but crashing in games

SpudMaster · 11 Apr 2008 at 22:32

As title, got my DFI LanParty LT X48-T2R up and running and have been overclocking. Tested my overclock in prime for 16 hours and all was fine, been playing COD4 today and it keeps locking up :mad:

Put everything back to stock speeds and it still crashes.

Could it be my psu (enermax noisetaker 600w) is dying? my 24pin plug recently seems to have become a bit iffy (if i knock it my board loses power). Also my psu only has the 4 pin power plug for cpu, do x48 boards need to have the 8 pin to be stable?

My psu is a about 2 - 3 years old so im thinking it maybe getting a little tired.

Or am i barking up the wrong tree entirely and something else is causing the problem?

Thanks

If its 16 hours stable I doubt it'll be the RAM, so maybe its GFX?

If he ran prime with small FFT then the RAM is not stressed so it might well be the RAM tbh.

True. My bad

I would try and eliminate problems one by one,

check your ram volts and timings, Memtest, prim bend.

try a different PSU if you can

try a difrent GFX card

it could even be driver related so make shore that all you chipsets and add on cards are up to date

make sure you have selected "Round off checking" under the Advanced menu - sounds noob but easy enough mistake to make.

I had the same problem, i got the HD 3870 XT ICEQ3 512MB and it was crashing like hell with games so i had to leave it at stock clocks and though no more of it :rolleyes:

When i got my new sound card installed my chipset temp dropped from 51 to 44 and its a lot more stable now, i couldnt get a stable clock with the chipset at 50+ :rolleyes:

I see your water cooled your system but whats your chipset temp at, i got my card clocked at 850/1995 now and it hasnt crashed once

My system is stable for 12+ hrs with orthos, havent got a screeny mind

Sorry forgot to say, i ran blend test in prime.

Just been playing UT3 for a couple of hours, no crashing in that game. So thought to reinstall COD4, played for about 4 mins and crash.

Gonna install more games n see if its just COD4 thats causing the problems. Then will try different psu and graphics card

Have you upped the north bridge voltage?

Maybe its heat from the graphics card when playing games that increases the cpu temp more than prime95, or the graphics card pushes the PSU too much & starves the CPU.
