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?

 

[omari79]

anyone?

i had one asus top my max oc was around 900mhz, maybe unstable clock?, the vrm.s have proper cooling?

 

[omari79]

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

thanks for the tip

 

[omari79]

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!)

 

[jason387]

Here you go dude. Looks like are gpu's are more or less the same. This is my 24/7 settings, 1150Mhz/1650Mhz.


Have a look at this for more comparisons.

thanks mate

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

 

[omari79]

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

 

[omari79]

ah damn it i couldn't resist your offer

here is my Dirt 3 run 1080P 2xAA V-sync OFF, rest of the settings maxed

 

[jason387]

Installing Dirt3 now.
EDIT: Downloading a copy now. My cd gave some data error check.

 

[jason387]

Here's a Hitman Absolution benchmark at ULTRA with MSAA at 2x.

 

[omari79]

i'll install hitman absolution too and post my run

 

[jason387]

Here's Dirt 3.
I just had my 2GB ram installed and it was being maxed out at 1.95GB

ULTRA settings with MSAA at 2x
