prime95 gives an error on stock settings... been like this since i popped new ram on.... how am i gonna explain that to the store?... i mean pc runs ok... but about 1 of 20 times that i play a game the thing goes back to desktop without an error msg... i bet its the ram.... since prime95 gives an error in the calculation even on stock speeds.... (well ram is tweaked all but 1T) but still isnt normal is it?
