this is why everyone loves the intel pentium dual core processors,they are so OC friendly.the stock clock for e5500 is 2.8ghz,but at this moment my cpu is running at 4.33ghz!!!btw im not using any water cooler or anything,its just an old intel cooler,not the stock cooler that came with this processor.the pc is running quite stable,without any trouble.
Just clocked a little higher .... 4.5 GHz on air .... AMAZING !!!!!
