[Solved] AMD Sapphire Radeon 6950 2GB Dirt Edition Overheating

I custom built my computer about 3 months ago, since then ive been having overheating problems, for a while i took a break from heavy duty pc games so i forgot about the problem, today ive come back to tackle the problem and since then its been overheating constantly.

It lasts about 2 hours in Dota 2 (last game to shut it down) so it takes a while, so i used a stress test with OCCT CPU ran fine for about an hour, i run the 3d test with my GPU and within ten seconds it shuts down with no warning, the temp hits about 61 before it shuts of ive tried everything i can think of and its still happening.

My specs are

Alot of people may say PSU but im using a 800W PSU so i doubt thatd be the problem, im also using a thermal take frio heatsink and have changed the paste recently. im all out of ideas so i hope someone may know the problem im tearing my hair out!

shouldn't crash until the 70's really.
download MSI afterburner and msi kombustor, and gpuz. set the 6950 back to stock settings in afterburner. run kombustor while looking at gpuz to see if your voltage is right for stock. if not see if you can unlock voltage control in afterburner's settings and raise/lower voltage so that it is correct.

Dunno if you can read the log, but i used OCCT to cause the overheat and using MSI Afterburner logged the temp and speeds

If you still have the warranty on the card I would return it, sounds like VRM over heating.

what brand power suppply? 800w with a shitty brand could mean there is a problem there

that psu is junk.
i am suprised it hasnt failed on you yet.
I say it is suspect
do not take offense, you didnt know, but yeah its a turd in a box

no problem.
Seasonic, corsair, or antech 550w and above can power that rig just fine. if you want to go 600-700-850 whatever its up to you. a quality power supply will not cost 28 pounds.
also make sure these supplies have at least an 80+bronze rating on them .
and yes, trying that card on another rig will definitely let you know if the psu is the culprit.
if it works, then go get yourself a good little box from corsair, etc.

good luck

ah. thats what i get for being a cheapskate on the LAST bit really isnt it -.-' i spent big money on my card and my board ect, so i thought i could buy a cheap 850W and skip the whole problem side and now im paying for it, thats 30quid down the pisser xD thanks though im gonna get a corsair 750W 80+ Bronze if it does turn out to be my PSU

As flint said, very nice choice.

The power supply is one part you should never skimp on, like you've just found out.

yeah i thought my PSU was good enough but turns out it probly aint il check tommorow cus i have another more powerful one a freind of mine has, the fact that the system just shuts down and doesnt crash graphically makes me think its the PSU i just wrote it of cus its a 850W

Congrats, glad we could solve it for you
