Now im at max voltage to 1.212, but I only have it set to 1.187, and power target to 130.  Oh and I run my fan at 65% now
That is right, it will boost 2 steps on voltage when you go into boost clocks . 1.187 will give 1.212 results .

You notice the stock was 1.150 and resulted 1.175 in game .

Just when I always think things are good, they arent =/... I dont understand how I can pass multiple tests and go through tons of stress and I would think no issues.  Been playing Metro2033 and my card keeps shutting down =/.  I havent changed much nor boosted as much..

Stock its 1215 boost and next step up is 1228.5, but I cant get anything stable...

 

I feel like all these flashes just messed with my card more...  Its not bricked as it works fine, but now its being more sensitive than before..

 

Could it be possible my P.O.S PSU is causing this instability?

I cant alt tab in some games now lol. I get a grey screen instead of the desktop. My second monitor is fine (hd3000) and can move mouse there and interact with things, and I can see the mouse on the grey screen, but no icons or anything like that lol

I returned mine to stock, to rule out some possibilities which it did (yay).

 

Ive been stress testing it for 45min, with the stock voltage set to 1150, max hitting 1162 and power target to 138% (as I saw some throttling and GPU-Z gave me warning).

 

So far its at 80 degrees right now, but no throttles.

In GPU-Z its giving me these two errors

Perfcap Reason:

VRel - Limited by reliability voltage

VOp - Limit by operating voltage

 

Other than thats its holding up so far

How do you get 138% on stock, and such high boost?

Dont get those numbers confused with my boost (those were my voltage values), mine is stock:

 

Details:

http://www.evga.com/Products/Product.aspx?pn=04G-P4-2686-KR

1019 MHz Base Clock

1084 MHz Boost Clock - 1084 is where it stayed at constantly

 

By default these cards can be adjust to 138% max power target on PrecisionX at least

Afterburner gives only 132%.
It changes however with your cards limit, new bios: 150%

Mine is 1006 base I guess, boosts to 1097 on stock bios with 100% powertarget.

Different things stress the cards differently. It wasn't unusual for cards that passed Heaven testing to fail in BF3, for example, so it's quite possible the Metro is just stressing your card in a way that Heaven or the other testing you've done doesn't  I'd say memory is probably one way that Metro is more stressful.  Have you tried dialing back your memory overclock?

Before BIOS mod I could get 1215 MHz stable
After BIOS mod I got only 1241 MHz stable (still needs further testing though)

That's only a mere 26MHz overclock. Is this a reasonable OC from stock voltage to 1.212v? Or my GPUs just sucked at overclocking?
Also, will I have more headroom to overclock the core if I lower my memory's overclock?

So if I raise my powertarget % to 150 in afterburner, the card will still only draw up to its hardware limit?
