A friend of mine gave me a q6600 so i had some spare parts and built a system out of it.I have a PK5 Deluxe Mobo with 4gb of DDR2 pc6400 micron value ram, q6600 ( cm 212+ ). So far i have only been able to get it stable at 3.3ghz at 1.4vcore. Ive got it to boot into windows up to 3.5ghz but i need a vcore of 1.5 just to get it to boot and i cant even get it stable. I am curious am i doing something wrong or is it just my luck with the chip i received.
