Thank you for reply.
I want to overclock at the highest speed available.Actually I want to raise the VCORE WITH that magic pen,but I can't find a simple table for vidmod.I found for core 2 duo but nothing for quads.
Thid CPU has the same architecture as xeon x5350 ES 1066FSB,B3.So i will use the information on my xeons also.Thank you again for replying,if you can help me I would apreciate that.
