Hello. Last year I remember people suggested to turn C1E and Intel Speed Step off, to have a stable overclocking. However with Sandy Bridge I see people raising the offset and reaching speeds up to 5.0Ghz
My questions are
1) what is the max temperature that this CPU should reach? 85C just as the 1366 and 1156 socket chips?
2) What is the max Vcore that is recommended for 24/7?
Right now I have my CPU running at 4.8Ghz, and the Vcore is 1.416V
I remember with the Intel Core i7 920 the max suggested Vcore for 24/7 was 1.3625
These chips are 32mm, so maybe they can tolerate a little bit more
I have read that when ocing sandy bridge you have to ensure you are are allowing the CPU the power it needs, and I dont mean voltages here. I mean there are settings to reduce the power draw of the CPU to save on power. So in this case, dont you have to disable DIGI and VRM to ensure the maximum available power is sent to the CPU?
don't go over 1.35 on Vcore and never over 1.9 on PLL or you could kill your cpu.
on your memorys, don't go past 1.65 because over that could also kill your cpu.
these sandy cpu's have a much thinner layer and they can´t handle that much voltage.
Please see below image of my cpu burn it test. Are these results acceptable or should I crank down the overclock?
