I recently purchased EP45-DS3L, with a e8400 3.0ghz and 4gigs of DDR2 800 Corsair ram. The system posts fine, runs totally normal just browsing the net, watching movies, etc. But when I try to run a game or 3dmark the machine completely locks up. I have read about a lot of trouble people are having with this board having similar problems. I have tried running memtest and i get no errors but the machine totally locks up about 1 minute into it. I have also run SpeedFan with prime95 to make sure none of my other components are overheating. Everything is okay as far as cooling goes. However when I run prime95 w/memory testing it locks my machine within 30 seconds.
At this point I'm fairly confident that I have the problem narrowed down to either bad RAM or Bad Motherboard or Bad settings on the mobo. I have no spare RAM to test with, and I have no spare Mobo to test with. I have seen where LSDmeasap has posted to some other folks some different settings to try in the bios and I am hoping that my problem will be resolved by something similar. Any help given is greatly appreciated!
