I have three s478 cpus. I just got a pentium 4 3.4GHz SL7E6 processor, and when i tested it, it didnt perform as well as a 2400MHz one. Also there is a high pitch sound coming from the machine when i'm using the 3.4GHz one. My question is: do you know such a malfunction of cpu? Or have you heard about something like this?
Thanks
