Anyways, I have it at stock speeds, same thing.


My problem is, everytime I run something graphical intensive, my computer crashes, there is no signal on the monitor, the fans and stuff are still running.

I have to hard reset to get it running again.

Removed sound card, same thing, NO ARTIFACTS AT ALL. Prime overnight stable and memtest overnight.

I also reseated everything, and reformatted.

The BIG weird thing is...

If I let it crash a few times... then restart... ( such as running 3dmark06, atitool, CS:S )
it will then be STABLE AS A ROCK, even after hours of gaming.

What's going on here? 🙁
 
So you have reformatted your computer and once everything was installed the same thing is happening?

Do you have anything that tries to force refresh rates maybe you set it too high.

Other then that I would try another video card and see if the issue is still there.
 
a) That's one NICE set of components!!! I envy you!

-This is what makes it a mystery to me. If not for this, I would've suspected your RAM timings. (I have the DFI LP nF4, but not the expert version.)

c) Still, I suspect that a likely cause is that your G Skill RAM needs considerably more-than-stock voltage. The stock voltage is only about right for low-voltage loving TCC5 ram.

Suggest you compare your bios vdimm settings (RAM voltage) to the settings for similarly configured rigs as reported in BOTH the stock speed & overclocked databases on DFI-Street.com. Compare your vcore (cpu voltage) to those in the stock settings database too, if you don't plan to oc (of course you do with that rig!)

Stock speed database
Overclocked database


EDIT: And try removing one pair of ram sticks. See what happens if you have only 1 pair of ram sticks in ONLY the orange slots. If it then works fine, look into ram timing settings in bios.
