Sli Overheating

[Bosstrich]

My sli setup keeps overheating when in the middle of games or at load. I have 2 Gtx 780ti's, 860w power supply and a asus maximus vi formula motherboard.

If anybody could help it would be appreciated.

You could start provide more information, your case, fans, cooling setup... stuff like that.

Are they reference cards?

Thank you I was about to say that.

This ^^^  and provide your temps because I've seen some people consider "80C" overheating when that temp will not damage anything and the card is fully functional.

They are asus direct cu ii cards

If the cards have no PCIe slots between them, you can expect higher temperatures on the upper card, as it will have its fan(s) blocked by the card below.

What kind of temperatures are you getting while under load?

I still need to know what case you have, how your cooling is in your case etc etc

I have a corsair 750d with 2 120 mm fans in pull at the front and 1 120mm fan at the back of the case in a push configuration. also i have a h100i at the top of my case with 2 fans on a pull configuratiion and my power supply pulls air from underneath my case

i have 1 pci slot between them and most of the time the top card gets up to about 80 - 85 degrees then continues to get hotter and then it crashes

Are you overclocking

set a custom fan profile in msi afterburner so the they don't overheat

only my ram to the factory standard that i brought it at which is 2400

80 - 85 degrees is fine for a GPU, possibly something else is causing the crash?

Try to find out the temperature just before it crashes, this would confirm whether it is caused by an overheat.

Do you use MSI afterburner or any similar GPU tuning utility? If so, what are your fan settings? Maybe your fan curve does not allow them to reach 100% speed.

Also an overclocked GPU will generally output more heat, which might be causing this

i am downloading afterburner now to run a custom fan profile and i will get back to you if it crashes again

seems to be fine afterburner is controlling the fans a lot better than them just going at 1 certain rate and then it overheating thanks for the sloution

[Bosstrich]

its still crashing and i have put the thermal cap to the max and the power limit on afterburner. i went to play borderlands 2 with my friend and it instantly crashed when i started it up.

[Bosstrich]

also i was running my first card at 70 degrees that's what afterburner said

[Bosstrich]

also i have had 15 of the crashes in the last hour all of which are event id 41 kernel-power crashes

[Bosstrich]

i have had 166 of them all together and its kind of annoying me now

[Bosstrich]

is there anything i can turn off in the BIOS that can stop my pc from crashing when something like this happens or is there a different solution for this
