Help with zotac 560 oc

[bobins]

Hey guys, i was hoping you could point give me some pointers on where to go next with the OC that I have attempted on my GTX 560 (non ti) 1gb card.

I started with MSI Afterburner, to get:

This produced no artifacts in Kombuster, apparently stable with temps around 70°C. So i proceeded to test this in vantage,



Vantage ran fine with max temp around 67°C. So i then proceeded to run a bench with Heaven Benchmark v2.1. However when running Heaven would crash out with the following error:

Unigine fatal error: "D3D11appWindow::do_swap():device removed"



I went back into Afterburner and to have Heaven complete a full bench without crashing out I ended up with the clock at 884 and the mem the same as above.

.

with a few runs going fine of heaven and vantage now scoring:



I decided to jump into some games. Firstly Wow with settings on ultra. It played fine for about half an hour, then crashed with drivers falling over and windows recovering them. I tried dropping the core and mem a few notches on the fly, but the same cash with drivers falling over happened again and again. I am struggling to know where to go from here with the benches running fine. I would be grateful for any suggestions or better ways to clock and test this card and how to go about fine tunning.. Is there a way i can push a little more power through or any bios unlocks for this card?

I will update my profile with my rig in a moment, also the cards not physically altered in anyway, stock cooler.

Cheers

Bobs.

did you try to overvolt it a little? try dropping the me clocks instead of core ones, ussually from my experience its the mem clocks that crash my oc

get nbitor from mvktech, up your voltage to 1087mv in your bios and you will hit over 950 on the core easy.....

Thank you for your pointers guys,

I have had another little play around with the card. I have upped the vcore to 1075mv, core clock to 930 and mem down to 2230 in afterburner.

I went a little higher but had artifacts in Kombuster so tested like this so far.

I've had a stable runs from Heaven, vantage and 3dmark 11, temps have crept up a little with a max of 74°C after the 3 benches.

Vantage:



3dMark 11:



I'm off to see if it can survive a gaming session

hoping not to get a repeat of the crash and drivers falling over. I may try push a little more then later if its truly stable.

Wish me luck.

Cheers
