Hi, I am trying to achieve a stable offset voltage OC on 3770K.

I know my stock VID:

1.1058v (taken from RealTemp)

I achieved a stable 4.7ghz manual voltage OC:

47x, 100bclk, 1.260v, VID 1.1709 (taken from RealTemp)

Now I have followed guides which say: manual OC voltage - VID = offset voltage.

So I have tried both the stock VID and the OC VID and then input these values as offset voltages.

For instance 1.260v - stock VID (1.1058v) = 0.154v approx. when I input this as my offset and boot up I am getting idle voltage readings of 1.33v, obviously not what I was expecting.

So I tried secondly, 1.260v - OC VID (1.1709) = 0.105v approx. when I input this as my offset and boot up I am getting idle voltage readings of 1.280v... again not what I was expecting.

So my question is:

I though the point of offset overclock was to make idle voltages as low as is stably possible without BSOD while at the same time allowing the voltage to increase when CPU requires it. So what I was expecting to see was an idle voltage of around 1.240v maybe spiking at 1.280v under P95 load. However another very odd thing is, when I load my system under P95 the voltage reading in CPU-Z DROPS!?!?! WTF, and that is with a POSITIVE OFFSET!

Am I being a complete moron here and missing something?

What is your LLC setting?

What is LLC? I have gone into Digi+ power settings and change CPU Load calibration to High and Power phase to optimized. I have a sabertooth z77 mobo.

Edit:

I see, LLC is same as CPU Load Calibration? OK well I have it set to high on Sabertooth z77. Also I just changed offset to +0.080 and I am stable in p95 for 30mins with temps not going higher than 88C. I started up Battlefield 3 as this has been sending my CPU temp up to around 85-90C when using manual voltage 1.260v 4.7ghz OC and now with offset OC it's reaching 65C so I assume I have offset correctly even though I am getting voltage readings of around 1.260-1.280v in CPU-Z?

I am a tad confused tbh



Don't...

Those temperatures seem fairly high. I would aim for around 60C on the CPU

TJ Max is 105C. 80C is fine.
