help offset

[andrea89]

Hello

Guys I would use the offset ...
but do not know how to set it!
now fixed voltage to 1.320/1.328

If I want to use the offset as I have to set, to have a low voltage at idle and in full in 1.328?

thanks

Figures just for example:

If you are stable at 4.6GHz and you found a manual voltage of 1.35v at load you could try an offset of -0.01 and maybe see 1.36 in CPUz...because negative offset is straight maths your next offset would be -0.02 and you'd likely as not see 1.35 in CPUz under load...job done.

You'll see this in Raja's guide: Positive offset doesn't work that simply because the calculation takes into account not only frequency but also current draw and temp of board etc so you entering a +0.01 offset may see the final load voltage increase by +0.015 or +0.005 because the processor is taking your offset as only one of the points to take into account in its calculations.....

As HiVizMan said, Vdroop is a design feature of the CPUs and well worth having that's why it isn't really recommended to use anything above Med LLC (which yes, counters Vdroop) you really want some vdroop left.

If you have no LLC and an offset of -0.015 this can give you the same voltage at load as an offset of -0.005 and med LLC (again figures just for example) showing that at the load end LLC and Offset may pull in same or opposite directions (+ or - offset)

OP the key point to remember or keep in mind is this. Your system needs to work, if it does work and you do not have a BSOD while doing your day to day stuff then your system is stable.

Stress tests are fine to check your temps but do not get to fussed by them. They are unnatural applications as there are very few if any application that will stress a CPU at 100% across all cores. And sad to say if your system can and does pass Prime85 or Linpak or what ever stress test you run for hours and hours that is no guaranty that it is stable. All that you have proved is that your system will run that stress test at that time. It might fail the next time or it might fail the first time you play your favourite game.

Now while you stress test the CPU is using all the voltage that is provided by the motherboard. Intel built in a protection device called vDroop. This lowers the voltage being used when your system is at maximum voltage usage. That is a good thing. It is how it should be. There is no need to even worry about it or spend to much time thinking about it. The Intel engineers did all the thinking for us all when it came to vDroop.

So enjoy your system.

So You Think i should leave it like that ? 😄 I never had a CPU that was stable on stock voltage on such OC. I did OCCT test on current config and it blue screens aftrer 2 min with 1.304 vcore on full load. Anyway when i was OC'ing manually i found that 1.36 was the minimum vcore that was not makeing blu screen after few passes of OCCT linpack. So, the best way to achieve this vcore with offset is going negative marker and just adjust it carefully until i get desired vcore under load ? And with negative marker it's (vcore on auto) - (the offset value) ?

[HiVizMan]

The offset method has been explained to you a couple of times now. Do not over complicate things.

Your OC failed.

Increase + offset value.

Keep doing this until your OC does not fail.

It is that simply.

[Arne_Saknussemm]

Yes this is really a bit of trial and error...like most OCing. If you have found 1.36 is your stable voltage set an offset of +0.005 and run your test and CPUz if the test fails or CPUz shows a voltage that is above or below 1.36 at load you have to adjust:

Go higher (+0.01...+0.015..etc.) if the CPUz voltage was lower than 1.36 or the test BSODd

Go lower (set negative offset -0.005....-0.01 etc)

Do this with CPU LLC set at regular for low vdroop compensation or Medium for more Vdroop compensation. If you leave LLC AUTO the board might be using high LLC and you wont really know what is going on in the background that is giving you your peak voltage.

If you use regular LLC you will need a bit higher offset probably than if you use medium LLC.

SO it seems i misunderstood You. I ve added + 0.035 and so far it seems to be quite stable . If it doesnt work i think im gonna use LLC medium setting as i dont want to run idle at high voltage and full load at lower. My english is not perfect and i thought that ARne means that - offset in fact is used to add voltage too... And well i need to add not lower the vcore. Thans for Your answers guys 🙂 I hope ill get stable on those settings which i have now.

[HiVizMan]

You will be fine I promise. Just do things in small steps and keep looking at your temperatures when you do a stress test.

[izajasz]

Thanks for support. I wonder when one would use negative offset? To undervolt the CPU on stock to be more "green" ? It seems quite logical that one wants to maintain stability on full load and if You use "-" marker it just undervolts vcore at both 1.2GHz and 4.6GHz .

[Arne_Saknussemm]

It pretty much depends on your processor but if you want a mild overclock like 4.2 or 4.4 the VID voltage programmed is often more than the CPU needs to run and often you can set a negative offset. Higher clocks than this 4.5 4.6 4.7 etc. and most often the CPU needs positive offsets.

Thank you guys very much 😄 I think i understand all so far 😄 If there are any problems i will contact Your for sure 😄
