    first i will tell you what Lsdmeasap told me... that llc is not safe to 45nm CPU... so you might want to disable it..

    the things that i would try.. are those :

    1.Drive Strength Profile.... in both Channel i would set it on 800Mhz...
    and give it a test.. if it work.. i would try 1066Mhz...

    try those.. 3 ... step by step... first do 1 .... see if it help... if not... try add 2...and so on...

    Hi
    Here's my settings if you want to try.P95 passed + 20x IBT+ MemTest overnight.
    Cooled with air..custom mounted Tunig...temps fine.Vcore is still kinda high (not fine tuned) and LLC is enabled getting about 1.29 in Windows.Dangerous with LLC...well,there's many opinions.

    I'm new with Gigabyte's boards and the bios was strange.I'm not Pro Overclocker either..just building comps to my son..MacBook is enough to me.In my case the key was not to pump MCH core too high.Reference voltages something like 0.67% to CPU and 0.72 to MCH.

    Anyway..hope you are able to read this written with my poor english.
