I'm guessing that's normal for CPU 4.2Ghz@1.265v/Cache 3.4Ghz@1.20v and a Kraken x61?

I know custom water will bring that down a lot more, hopefully October I'll have that done, it'll be my first custom loop biggrin.gif

You need that much voltage for 4.2GHz only?

Honestly I haven't tried any lower yet.
Took an average voltage of other people's voltages (high and lower), was going to have a little play today anyway.

You should do that, it will bring the temperatures down considerably.

Don't know what's going on, I've dropped it back to 1.240v, but all the sensors are still reading the cpu core as 1.267v.

Try a bit lower, like 1.22V

Seems I can't use adaptive at all, I can set it to 1.24v manually, but as soon as I go back to adaptive it'll set the voltages to 1.265v not matter the max cpu voltage set.


This will read 1.267v in Windows:

Hello

Adaptive voltage cannot be forced lower than the default turbo VID programmed by Intel.

Ah so manually it is then.
So how do we get the voltages to lower on idle.

Just started OCCT temps a better at 1.223, but it detected an error in core 3 within 2 minutes, at least it wasn't a blue screen, so my voltages can't be too off.
Will try 1.23v.

1.23v blue screen.
1.24v blue screen or error at 4 minutes.
1.25v still going at 30 minutes but package temp is hitting 82c max, pretty much the same temps as i was getting with 1.26v.

Honestly I'm fine with 30 minutes of OCCT there's nothing I do that stresses the cpu like that, most stressful thing is converting raw video to h264.

in manual override... c-states.

if the CPU can hold up at idle, you can attempt to run a negative offset with the turbo voltage you had before.

Easy answer is "Don't". Leave it on adaptive and consider the very real prospect that Intel set VID for a reason. I tried chasing this exact question and ended up right back to values assigned by VID. Mine is considerably higher than yours at 1.298v at anything 4.2ghz or higher. Going to manual, I was able to drop to 1.260v at 4.2ghz in manual mode but it ended up not being stable for more than 30 minutes. I ended up setting my adaptive turbo mode to the ViD value and it's been fine ever since. I even went to 4.3ghz with a modest increase in Vcore to 1.310v and it's been stable as well.

Also, I had the same thought you did. "Honestly, I'm fine with 30 minutes of stress test because I don't push my system that hard." I've since realized that I was wrong. Playing video games caused my system to hard crash after 2-3 hours. I went back to realbench and the system failed at 130 minutes...which meant I was unstable. I increased my VCCSA voltage slightly, ran the realbench for 4 hours with no failures and now I can play games without crashes. It should be clear that games like "The Divison" don't put nearly as much load as RealBench but the system fails all the same. So you might want to keep testing until you can run realbench for 4 hours at least. Also, I would avoid manual mode for voltage as the system will not let you enter a low voltage state like adaptive does...and temps should change much either way.
