its not like the card is cooked or anything,

i have the GPU in my Sig rig already OC'ed, to 860Mhz Core using 1.10v, today i tried an OC of 900Mhz core using 1.164v but after 2 min or so of OCCT (temp reaches 85C) the screen goes blank and i have to restart the system.

is it a PSU issue or do i need to apply less/more voltage?

yeah the VRM.s are properly cooled but is my PSU enough for this OC'ed system? i am asking this so i can rule it out and concentrate on the raising/lowering the voltage only

Try increasing voltage further. Use Unigine heaven on max settings and max resolution to check for stability.

i applied a good thermaltake thermal paste to the GPU yesterday instead of the stock one in order to improve the T (line method) but it ended up with the same result -_-

anyway thanks for the advice but why should i use Unigine instead of OCCT? is it more reliable?

Yeah. It's more practical as well and gives you more of an idea of real world scenarios rather than a burn in test to check temps.

We have a rather similar setup. If you want we could always bench to check out performance

You have an entry level psu, so you can't rule that out either really. But I would try to just increase voltage and see what happens.
But you have to remember that it's not certain that you can oc more, I have had several cards that won't oc at all or oc a lot. Basically the oc lottery!

thanks for the offer mate, i will try to increase the voltage a bit more to reach 900Mhz core (hopefully) then bench using Unigine heaven on Max settings 1080P and compare my result to yours

OK mate,here is my benchmark result from unigine heaven 4.0
kindly note that i used the extreme preset which only allowed a 1600x900 windowed res, awaiting your benchmark result

Edit: here is my run @ 900Mhz core 1.15v, extreme preset (i hope this means my card is stable!)

Have a look at this for more comparisons.

our unigine score are almost identical but you below me away in 3DMark 11

core @ 900Mhz



back to the main topic, i actually ended up needing less voltage for a 900Mhz core in Unigine and 3Dmark 11 (1.15v) than in OCCT (1.16v)

didn't try gaming yet @ 900Mhz but i think it should be stable now that i finished multiple runs with Unigine and 3Dmark

You should definitely be stable now. I think in games my gpu is roughly 8fps faster than yours. If you want me can run a few games which have an in game benchmark. Just let me know

no need, thanks, you already helped me a lot and i don't want to feel any worse about my PC

BTW your score is higher than i7-3930K @ 4.9GHz + GTX 460 1GB @ 936Mhz/4200Mhz



at first i thought that the reason for the big difference in our 3Dmark 11 scores is your CPU, but its actually your GPU too or it must be
