my supposed 2.8 (533FSB) that i bought of ebay the other week is only running at 2.4, in the bios it only allows me to go up to 2.4 unless i change multiplier factors etc. seperately which i dont want to risk doing. could it be a crappy chip? in the "my computer properties it says it is a Genuine Intel(R) CPU 2.80GHz but then it says 2.41GHz.
