prime 95 error with a7n8x

i just bought an asus a7n8x rev 2 bios 1007 , running it with 1 stick of corsair ddr400 xms pro and an unlock 2800 barton, atm am at (200 x 12) 2400 mhz and for some reason i cant get prime95 to last more then 1 min without error any one can help me on this ? its really frustrating switch from msi kt6 delta to this asus board with nforce 2 and it doesnt seem to be better.

any help would be apreciated thnx.

Try upping the ram and CPU voltage a bit (if it isn't too high alread). This was pretty much the case with me, I tried to run prime just after I got my new system and it crashed all the time.. I tried it recently and it runs flawlessly, might just be a case of letting it burn in a bit ?
