Gtx470 very fast green screen intermittently at 1.087v oc

post #1 of 4
Thread Starter 
Hi,
I have a gtx470 that's been oc'd since day 1 ( 3 month ) to 727mhz core on stock volts, of course i tried voltage oc'ing but ended up settling for oc with stock volts.
Yesterday i decided i was just going to max out the volts at 1.087v, got 827mhz core with no artifacts in occt, had only tested though for 5 min as i have heard of the horrer storys of dead cards while stressing for too long, temps topped out at 86 and my ambient is around 18c.
Have noticed on desktop around6+ times that the whole screen will flash green for a very split second, has allso done it maybe 3+ times while gaming.
Anybody heard of this problem before?
max volts oc was only done yesterday so the oc or the volts is the culprit for sure.

I haven't heard of it, but it sounds like it isn't stable. Bump down your clocks a bit and see how it goes. 5 minutes isn't long enough to stress test your video card also. I usually stress test it for about 40 minutes, and never had any problems doing so. Other people will tell you longer, but it's personal preference / what you do with your computer.

have you tried overclocking to 800-1600-1800 with less voltage?

Mine only uses 1.025 for the above OC, and it seems to be the sweet spot for 470's.
