Changing from Manual to Offset Voltage

post #1 of 15
Thread Starter 
Hi OCN

Please I would like some help.


I am stable at 5Ghz and have been for some time, but after some reading, i decided today to change my voltage from manual to offset.

But when I booted back into to windows to stress test(P95), before applying an offset value, the temps instantly shot up to 80+.

I shut P95 off immediately.

I went back and changed back to manual vcore settings, and P95 again all at 60c - so i can rule out the H100 acting up.

Obviously I am doing something incorrectly, please can someone point me in the right direction.

Many thanks.

Three things will help you determine what offset you should be using, they're Prime95, CPU-Z and Realtemp (be sure to have the updated versions of both CPU-Z and Relatemp).

Open Prime95 and hit the blend test, open cpu-z and note down the load vcore, open realtemp and note down the load VID. Now the difference between the Vcore and VID is the offset amount.

Say your vcore is 1.425 and your VID is 1.385, the offset would be a positive value from the VID, 1.385 +0.040 = 1.425v. So +0.040 give or take would be your offset value for 1.425.

If you vcore is lower than your VID, then it would be of a negative value from the VID. So if the vcore is 1.355 and the VID is 1.385 offset would be 1.385 - 0.030 = 1.355v

The offset value always works off the VID not the Vcore. Hope that makes sense. thumb.gif

Thankyou munaim1 for your quick reply smile.gif

OK so, under load, before changing to offset mode in BIOS, Vcore is 1.414 and VID is 1.3911.

This makes the offset value +0.0229.

So if I change the BIOS to offset mode, and enter in a positive value as close to 0.0229 as possible, it should work , correct?

Yeah that's correct, however because the increments are very small between voltage change, you may have to increase or decrease the offset a little from 0.02229 to get your correct load vcore. Try 0.025v and see what load vcore you get. If it's still higher than 1.414 then try 0.020 and so forth.

thinking.gif never ever seen this before.

Could you set it back to manual and post screenshots of your BIOS settings. A FAT32 USB stick and F12 should do the job. Thanks



EDIT:

A quick search indicated it could be something to do with the HDD, not so sure. Might be a good idea to check the RAM and HDD when you get a chance. Chkdsk for HDD and memtest for RAM should be okay. Run Memtest for a few hours, 6-8 hours should be fine.

I'd suggest playing with your LLC levels a little bit, see if that helps?
Also, out of curiosity, if your speedstep is disabled, what's the point of using offset?
