470GTX Issue? Cuts out.. Heat? Power?

I did that. Last night I loaded optimized defaults.. no OCing on the q6600. And still got the signal lost after an hour or two. It only happens when I OC the card. If I leave the 470gtx at standard clocks and up the cpu. No problems.

Weird. Maybe my psu isn't handling the extra voltage well? Should I force the voltage to stay constant using Afterburner? What you think?

I thought that, but I would have though that it should have coped ok when the CPU was at stock.
Can you run the card at 700-750mhz on stock voltage ok?
Test for stability in Furmark or Heaven...

PS I don't think the card needs more voltage personally.
 
haven't tried upping core without upping volts. I'll give it a go tonight.

My PSU is a 700w Artic. Not a brand name. But still plenty of 5 star reviews. If you google Artic 700 you'll find it as top result.

Thanks
 
Just to chip in, I'm having a similar problem with my Asus 470. I get the same monitor cut out during gaming and FurMark when I OC my card but not when I leave it at stock clocks.

I'm using a 700W Coolermaster Silent Pro PSU but I've tried using a seperate PSU just to power the card and it still happened so it's probably not because of your PSU.
 
Theres only 2 reasons really for those symptoms:

Failing/insufficent PSU (or unsmooth mains power supply)
BGA soldering failure
 
could be a bad card. it'll work fine at stock or mild overclock but wont reach the heights it should. should really try the card in another rig just to be sure, keep the case open too i suppose
 
I think it is the PSU. I also have a Arctic 700W (it's not even 80plus, it is only up 70% efficiency according to the official site) and was using it before I upgraded it to my current Sapphire Pure 625W. After I upgraded to the Sapphire Pure 625W, I noticed that in HW monitor, the various voltages is much more solid with the minimum and maximum at minimal difference, comparing to the the Arctic 700W.

I suspect the GTX470 is not getting stable enough voltage for the OC from the Arctic 700W.

+1 fluctuating voltage is no good for OC's...

I hope not. I have a Seasonics 850W PSU and it only does this if I don't give the cards enough juice. That is contrary to what you say as more juice = more power needed from the psu so it should be more unstable at higher voltages.:confused:
 
Well similiarly its a power issue :P (tho normally not enough vcore would result in crashing or corruption rather than just dropping out).
 
Yeah I think some of you may have hit it on the head..

This seems to be happening on random 470's. Not just the Gainward revs. So that rules out likely soldering etc.

I'm thinking possible fluctuating power supply. Don't have anything to connect up in the mean time to test the theory.

Just strange that the card completely loses signal with the screen. And not at any significantly loaded times. For example, when I'm loading a save on COD the fans go up massively! Probably from all the mem work raising temps right? Then it won't be til everything's smooth and nice, fans audible; not 80% though. Til it will just black the screen and the blue light will flash on my monitor (indicating it's searching for a source - same thing it does when the monitor goes into standby).

I'm on the search for a good power supply now. I want to go up in watts - just so I can hang on to it for years to come. Pref modular, reliable brand. What you think?

Thanks all.

Power supplies, monitors and cases, are the best places to put money into because they are not upgraded nearly as often as other components.
