CPU voltage always stays the same

thebennyboy · 31 Jul 2015 at 00:44

No problem at all. It should be lowering it's voltage when it's idle now.

When stress testing though it's going up to 1.364v so I cancelled the stress test

Any idea why that could be

thebennyboy · 31 Jul 2015 at 00:54

Try setting the offset to 0.07, then boot into windows and stress test again.

Drake5 · 31 Jul 2015 at 01:00

With that max voltage is 1.210 so don't think itll be stable

Also would putting 1.364v through the motherboard for about 10 seconds damage the mobo or cpu

thebennyboy · 31 Jul 2015 at 01:02

No, that board is safe up to 1.4v.

It wouldn't have done any damage.

Set offset to 0.095 and try stressing again.

Thanks

Will try

Drake5 · 31 Jul 2015 at 01:09

That has given me a max of 1.234 so not quite there

thebennyboy · 31 Jul 2015 at 01:11

Give it 0.100 and that should do it.

Drake5 · 31 Jul 2015 at 01:23

Appreciated

Stress testing it does seem to be sticking at 1.234 and only some times going to 1.239

thebennyboy · 31 Jul 2015 at 01:24

That's vdroop i think. Is it stable?

Drake5 · 31 Jul 2015 at 01:37

It seems to be

Just stress tested on RealBench for 15 mins without issues

thebennyboy · 31 Jul 2015 at 01:39

Sounds good, is the voltage lowering when the CPU is idle?

Also, if you get any instability try increasing the offset very gradually. For example, your on 0.100. increase it to 0.101, then 0.102 etc. I think you get the idea. You shouldn't get an instability if 1.24v was your stable overclock before.

Drake5 · 31 Jul 2015 at 01:45

Yeah it's going down to 0.805

Does that sound right

thebennyboy · 31 Jul 2015 at 01:47

Yup, sounds good. It'll run much cooler when you're not using it AND use less power. I have my 4790k using offset, it's a very good method of setting voltage providing it's done correctly.

Cheers

Much appreciate your help

thebennyboy · 31 Jul 2015 at 01:58

No problem at all.

Drake5 · 31 Jul 2015 at 10:33

If I did want it to go up to 1.240 would I set 0.105

MadMatty · 31 Jul 2015 at 11:18

Manual mode is probably easier to work with as you don't need to do any maths to find your offset. Also with offset you need to add a little extra to account for the slight overvolt the cpu does when executing avx instructions. With manual mode the system will automatically take the extra +0.010 it usually wants.

As long as you have c1e and eist/speedstep enabled the multiplier and voltage will still drop on idle to 0.800. Just don't use cpu-z to confirm it as that only looks at the vcore value you have set and not what it actually is.

Drake5 · 31 Jul 2015 at 12:02

I'm using Hardware monitor but on manual it just always keeps it at 1.239 so I need to look for c1e or eist/speedstep in the bios

It will downclock the CPU but not the voltage

Drake5 · 31 Jul 2015 at 12:21

I've just checked the bios and those modes are enabled but the voltage is still always max 1.239 on auto
