Thanks

Yes 1293Mhz boost it difficult to be reached and be rock solid, except if you are lucky.

Suggest to lower max boost at 1212 for a start and increase it until you find the sweet spot.
If you like post the bios you were trying and caused you issues, to take a look and make it for you.

OK everyone, new member here and I could really use some help with my EVGA GTX 660 2GB SC.

I received the card about three days ago, and for the first 24 hours it was running great. I ran furmark burn-in for 1.5 hours and played my games and everything was good! But over the last two days problems have arose...

When I run games or furmark burn-in, my monitor goes black or the computer reboots. I've tried everything I cant think of...
I've updated my Mobos bios, uninstalled and reinstalled different drivers (including betas) but nothing seems to help.

The card still works fine for non graphics intensive uses such as web browsing and basic programs, but furmark and games cause either a black screen forcing me to reset my computer manually or a reboot on its own.

I'm at a loss as to what to do, here are the rest of my computer specs-

A8-5600K
Asrock Pro4FM2
8 GB gskill sniper at 2133mhz
64GB Crucial M4
1TB Sammy Spinpoint F3
Corsair CX430
HP 2311x @ 1080p

I honestly dont believe my PSU is the problem. Its only two months old and I've never had any problems with it. And the weird thing is , it has proven it self capable of pushing the 660 as it successfully did so for the first 24 hours with no problems, not to mention it also provides 32 amps on the +12v rail which is more than the required 24Amps...


Any suggestions?

I'm leaning towards doing an advanced RMA with EVGA...

Stop using Furmark for a start. Worst program you can use to stress test a card. Its not real world and a game would never ever come close to using that much power. Use EVGA OC Scanner. Getting back for Furmark. Nvidia has even built in their drivers to throttle the card when running that program. It is evil and destructible.

First bios is just capped @ 1215Mhz.

Second is using raised voltage from 1.1875V to 1.215V, higher power limits and capped @ 1254Mhz.

hi melody,

it seems that any setting above 1215mhz boost (ex 1228mhz) will cause heaven 4.0 to crash at a certain point.

i might think that 1215 is the sweet-spot for my card. im a bit disappointed since its an asus direct cu ii OC edition.

btw, can i request a custom bios from you? can you modify this bios and have it locked @ 1215mhz boost clock, 120% power limit, 30% fan speed and 1.2125mv?

if its possible, i would highly appreciate it. thanks wink.gif
