can someone verify this for me. my x2 4400 is pretty good. i got it at 11x255 right now for 2.8Ghz. cpu0 or core 1 is great. it will pass prime95 for hours no problem. cpu1 or core 2 sucks as it can't even pass the 1st iteration in prime95. is it correct to say that chances are alot of dual cores have bad core 2? i can play games on cpu0 by changing the affinity and it would be fine. if i change affinity to cpu1 to play games, instant crashes . i also tried aquamark 2k3 and 3dmark 2k5 with affinity set to both cpus, aquamark passes, but 3dmark fails half way thru. i'm running a pair of g.skill pc3200 and my vcore is set at 1.55. man i would love to have two good cores instead of 1 good and 1 bad .
