i7 2600K + Asus P8P67 Deluxe OC help

post #1 of 6
Thread Starter 
I thought overclocking sandy bridge was as simple as changing the multiplier, but something is going wrong.

I'm not sure if this problem is coming from the motherboard, cpu, BIOS, CPUZ itself, or Windows.
(I have the newest beta bios)

This is what happens at default/stock everything.

Idle


Load



I go in the bios and choose "OC Tuner". It chooses a 43 multiplier and 103 BCLK. The BIOS also says "target speed: 4300 MHz" or something like that.
However, the computer doesn't run at 4.3 GHz.

Idle


Load



And now, CPUZ alternates between the 3rd image and the one below every 2 seconds:

SB automatically slows down at idle to save power and improve the life of the chip. There are bios features that change this, but I haven't played with them since I like that it does this. It speeds up again near instantly, so its really not hurting performance.

Also, I would leave BCLK at exactly 100. People have said changing this can destroy system components. I don't know if that's true, but its a warning scary enough to make me heed it for now.

You need to enable EIST, Turbo, C3, C6 states then set the Turbo Multiplier. Also, there's no way you're actually running 218MHz on the BCLK considering the max any board can get is 110-112.

I'd say something is wrong with your board or CPU.

You need to download the latest version of CPU-Z. I think it is 1.56.2.
