Freeze

[Supergrover]

Thats pretty hot MB IMO, like sswilson said 1 hour of memtest is nothing let it run overnight and orthos i go 10-12, as I have thrown errors @ 8.5-9 hours but for me if it hits 10 hours then it it usally stable.
How long before it freezes in game?

I will set memtest to run tonight before I head to bed. Computer crashed again just a few minutes ago after about 30~40 minutes of playtime. It can take up to an hour to freeze but it also freezes frequently sometimes (3 times in 5 minutes). In other words, totally unpredictable.

Edit: I am not overclocking, although my memory timings are pretty aggressive to begin with (2-2-2-5)

I used to run that board too (same CPU and RAM as well), and it never got that hot. Then again your running SLI which might contribute to the heat.

The board comes with that blower fan to clip onto the heatpipe, maybe try using that to see if it helps lower the temps.

EAttached the blower fan and it makes very little difference. MB temps are down 1~2 degrees while CPU temps are up 3~4 degrees.

Edit: Noticed while I was attaching fan that one of the MB heat sinks was loose (see picture). Could this be contributing to the extreme heat of the MB?

[sswilson]

Could be part of the problem, although I suspect that particular heatsink is covering VRMs rather than your chipset, so I doubt that's what temperature reading you are seeing as "system".

Could be related to your overheat / shutdown problem.... VRM issues on my vid card displayed much the same symptoms.

Do you have some TIM around that you could re-apply?

[ebdoradz]

You could try to play with only 1 video card ....

maybe one of the 2 card overheat ... you coudl also see if your mb temp are lower with just 1 card

if they are, then you would have to look into more cooling

How loose is that heatsink? I know mine wasn't extremely tight, you could wiggle it a bit. Just push down the white plastic things in each corner to ensure it's fully clipped in.

As ebdoradz said, just try running a single video card in the top slot. It's possible the motherboard temperature sensor is somewhere near the 2nd PCI-E x16 slot, thus if the video is pumping out heat right on it, your going to get a high reading.

Just ran memtest for 10 hours straight with no errors, so I can rule out my memory as the problem (although all 4 dimms are extremely hot to the touch).

Edit: Just removed bottom (farthest away from CPU) videocard and my MB temps went down dramatically. It is now showing 40~43c. I will loop 3Dmark while I am at class and hope that it doesn't crash while I am gone.

whats the temp of your GPUS load in SLI and single under load? anyway it would be good if its just a GPU temp issue as you can fix that. not sure about the RAM being hot though--theres some good RAM cooling fans avaliable though. What size is your case anyway? good luck and then you overclock that cpu

SOUND drivers can be an important player in this as well. My AC97 gave me hell until I had it pinpointed. Updating the Realtek drivers did not help. The games+multimedia kept on frikkin' freezing my ASUS mobo. Since my mobo is Nvidia based (NForce 2), I used Nvidia sound drivers, and the problem has been fixed since!!! Works great too.

The way I found out was playing multimedia files and DVD without sound. This was an accident - a half uninstalled player that did not use sound - but the crashes stopped. Upon exiting a multimedia program, it usually crashed every time, but no sound device, no crash.

Perhaps you could try uninstalling the audio in the devices panel as a test. Not sure your games would start though.
