Hey guys,

So, I recently bought an ASUS GTX 670 video card. In order to test stability I immediately DL'ed Furmark to stress test it. My issue is that after 5 minutes of testing, the display loses signal (HDMI port). I know Furmark is a little extreme, but I'm not overclocking, this happens with stock settings.

Temperatures during the 5 minutes go from 30°C to ~80°C at the time of crash. I know this card can pull 97°C before it shuts itself off. So I don't know why is it losing video.

Any ideas on what the issue could be?

try and increase your fan curve using msi afterburner as it seems like your gpu is getting a bit on the hot side i have the exact same gpu and you should not be getting close to the temps you have said under load

Ok, let me try some fan profiles on MSI Afterburner. I think that might be the issue since the fans remain at 10% speed on idle with 47-50°C temps.

Also, I think the case is not helping. I have a Lian Li PC-Q25B which has little space for air flow (I know, but looks pretty neat).

OK, I used MSI Afterburner. Now temps sit between 34°C and 70°C while running Heaven benchmark. Has not crashed yet, however scores seem too low with ~800 points.

Try and increase your power target to 117% and it will help with the boost clock of the card i have my card set at gpu clock 1034mhz and mem clock at 6600mhz with a power target of 117% and during load the boost clock hits 1202mhz

when you benchmark make sure all non essential programs are running in the background e.g. firewall and disable your ethernet connection through device manager and your scores will increase
