Overclocking problem with P8P67 Deluxe

[Arcadio]

I got a P8P67 Deluxe and a 2600k processor. I use the ASUS utility to overclock the CPU to 4.5x multiplier and 1.24v cpu voltage. It works fine and it's stable. But if I try to overclock with the same settings in the BIOS instead of the software utility, I get BSOD's when running stability benchmarks. What could be the problem?

I want the overclocking settings to be stored in the BIOS so I don't need to run the ASUS utility every time I reboot the computer.

Did you run something like CPUZ during stability testing with the Asus utility and verify that the voltage is actually 1.24 ?

Interesting... CPU-Z says "Core Voltage: 1.328" during stability testing.. So does that mean that I should set the core voltage to 1.32 in the Bios? The sensor from the Asus Utility also says 1.32v during stress testing.

I would set at 1.3, and see how that goes .. 2600K at 4.5 & 1.3 volts is probably typical.. You may have to go a bit higher ..

Once you establish a stable overclock, set the voltage control to OFFSET mode, and use - offset to bring it down to your lowest stable value..


Example: You determine your lowest stable voltage using manual is 1.3 ... When you change to OFFSET mode , it goes to ' 1.45 '.. Use ' OFFSET ' mode and a value of -0.15 ...

That way, you will idle at a nice low voltage, typically less than 1 volt, then under load, it will rise to the voltage needed for your overclock...


You may have to experiment with the OFFSET value to find a balance; it is not usually as precise as shown in my example...
