Troubleshoot GTX 460 SLI shutdown

post #1 of 5
Thread Starter 
Sorry for the long post.

So I bought two GTX 460 768 cards today. I have them in my 1156 system with a gap between the cards, 750HX.

They (or the game) shut down after 5 minutes in Cysis and 1 hour of NFSS. The comp still works just the games go black and shut down.

I used OCCT to load test them, I can only get one to load at a time with this program. SLI on per nvidia control panel. FPS seem to confirm this.

They max out at 79c totally stock. Using a digital temp gun the end of the card where I think the memory is runs at 200-218deg F(depending where you point) or 103c. The rest is about 150ish F.

No GPU OC or any mods at all.

How can I tell how or what card might be shutting down? I cant see GPU memory temps in GPUZ.

These things run very strong and I am totally impressed with the power. I would like to save them but have 30 days to try, or until I lose patience.

Is there another good (free) program to help test these? Links?

Why I am blaming the cards is my GTX570 and my previous 5870/50 cf worked no problem on the same system.

you can use a program called furmark it supports multi-gpu and its free smile.gif

As for being able to tell which one is causing the problem you would have to pull out one card and test it and see if it causes the problem. If it doesn't test the other card to confirm if its a card issue or not.

So, after 5 min in Crysis, the game closes itself and you are kicked back to Windows desktop?

I suppose the gap between the 2 cards is not huge.
Generally, both cards do not max out at the same temperature (79C). The top card has to be higher in temperature as its (intake) ventilation is poorer.
Double check this with a few programs (GPU-z, Afterburner...etc).
If the problem is due to thermal, then it is safe to assume the top card, unless proven otherwise.

Which GTX460 are those exactly? Reference centrifugal fan cooling?
And, that 103C memory temp sounds toasty to me.

And, try MSI Kombuster to test your SLI setup.

On my p55 MOBO I have a 1 slot gap between the two cards. They are Galaxy cards. They seem to have a large sink and the RAM also has sinks.

I have not been able to make them shut down without games at this point.

About to go to bed. First short run on Furmark does not work GPU#2 either, (EDIT FIXED furmark both being tested)

Edit, turns out it must have been my old drivers from the GTX570. A clean sweep and re-install fixed my problems.

Cards run good, I have the volts at .925volts with an OC of 800/1900 with 73c/66c after 7 minutes of Furmark.

I am not a big overclocker and I like the lower heat and less power use. If I dont need the OC I might run the clocks at the factory 700/1850 settings. With low volts (.9) and a custom fan profile I was running 64c/59c under full load.

Even at stock speeds the two of these are faster than my outgoing 5870.
