I'm giving up...can't comprehend at all this board.
Every time i think to have found a stable config it reveals to be faulty. The last week i've got it the CPU to 3.45 Ghz and RAM at 863 4-4-4-12 1t, wich passed >8 hrs prime95 blend and many hours of gaming. It lasted three days and then started random freezing while gaming, surfing or listening mp3. So i've run again prime to see wether was an OS issue or not. Well, prime errored after 2 hrs....why?!?!?!?
So i've spent another lot of time searching new settings with no luck. Thinking of RAM issues, i've also run a whole night memtest wich passed without an error.
Giving away the 863 4-4-4-12 1t settings, i've then managed to reach a stable config with the same 3.45 Ghz on CPU but RAM at 1104 and 5-5-5-15 2t.
Again, 10 hrs prime95 blend stable, another whole night of memtest, and played for a couple of days...till last night when the system locked while playing bioshock. What the hell?!?!?! What's wrong?
This mobo is really drivin' me mad, i'm thinking to give up with sli and nvidia chipsets...will swap to intel chipset, an x48 and a crossfire config...
