This way, you can always reset quickly, when you want to... thumb.gif

Does override deal with "+"/-", or i can just input volts and just vhoose override?

And what are these extra thing, you mean input the things I changed?

I hope i did this right:
Bios defaul
-change multipliers
change volts
set memory settings
enable EIST
enable turbo mode
C-States to Auto
voltage mode to adaptive
Save and exit...

This is how i have it ATM, it lowers VID in HWInfo and cores drop as well
I only change it to adaptive to see the VID drop, otherwise i do this instead.
Bios default
Input multiplier voltages and set memory
Enable EIST and turbo*i am not at my pc now, i forgot the name*
C-States to C7s
Voltage mode is kept at auto i believe with bios defaults.
These settings dont show a drop in "VID" in HWInfo, but shows a drop in "Vcore", HWInfo has a couple of sections for voltages.
I am using an MSI board so some of the settings/wording is different.

I always wondered if Im doing this power saving modes correctly.
What should i go with?
Thanks in advance guys!!

Just choose Override and type in the volts you need. VID drop doesn't matter whatsoever, what you want to look for is your VCore drop.

4790k 4900mhz @ 1.33V Max temp 74C* Prime 27.9 with 1344-1344. with this settings this night i make 11 hours testing without errors.
Cooled by 1 big custom loop with R9 290.
2xEK DDC 3.2 PWM + 2xnexxxos ut60 480 + 1xUT60 240 + EK Supreme HF jetplate 6.

now i tested with 5ghz.

Well hit a brainstorm this morning and managed to get my 5.0 to pass two stress points. Successfully encoded in handbrake maxing at 82 degrees and passed Intel xtu bench.

cbc2bea1bb1582c939e87fbe0559ab1f.jpg

Had to adjust eventual voltage input to right under 2.0 and also down clocked the ram and uncore. Did this before work so couldn't stress it for its full run and couldn't adjust from there to make it better but this is promising!!

use prime95 version 28.7 with 1344-1344 fft, for me this is the best test for full stable cpu.

10 intel xtu benches in a row works for me for a quick check.

Long checks = 1080p 2+hour length encode from mkv to mp4 lossless 1080p output in handbrake. This is one of the most intense uses my CPU will ever face. Synthetic benches like Prime are ok, but I tend to avoid them. Especially tests like intel burn test which has shown to cause your CPU to throw a higher voltage even when it is on manual.

How many here bother to dial in all the sub-voltages down as low as they can get away with? Or do most of you just leave them on auto and if they work, they work?

I just spent most my day slowly raising input voltage to correct a crash on GTA5, when it was too low cache voltage causing it...

It worked fine on auto, but I find auto... over generous...

For example, auto puts SA @ +.3v offset, but +0.03v works fine...

I cant help myself and I wanna tweak it all so its just right tongue.gif

It depends on the individual CPU, it seems. On mine, without tweaking secondary voltages I could only do 4.7GHz at 1.32V VID (1.344V Vcore) and 4.8GHz was out of the question even at 1.4V. Also, my memory wouldn't go over 2200MHz without getting stuck at POST. After messing with all those other voltages (Mainly SA, IOD and IOA), I could get 4.7GHz stable at 1.285V VID (1.312V Vcore), 4.8GHz stable at 1.33V VID (1.36V Vcore - it's quite stable at 1.32V VID and 1.344V Vcore, but it gives me errors on OCCT and Prime95, but doesn't crash downright) and all that while I was able to do 2400MHz on my RAM. Quite satisfied reallly. I'm thinking about sticking with 4.7GHz for the lower volts, temps and noise, as the performance difference is negligible at best. But I digress.

What I would watch out for is the actual voltages you end up with. VCCSA for example should be about 0.815V at stock, so +0.3V lands you at 1.115V. Quite high, but safe, I guess. Some boards, however, default at 1V for VCCSA (mainly some Gigabyte ones, I think), so +0.3V lands you above 1.3V which is dangerous. I, for one, wouldn't go above 1.05V for VCCSA and 1.15V for IOA and IOD.

These three should only make a difference when running high speed memory, however (Or not, it's worth a shot). VCCIN (Input voltage) and VRING (Cache voltage) are far more important and can more easily make or break an overclock. Also, it seems higher VRING leads to needing more VCCIN (Thank @jdorje for that, not me), so keep that in mind. Also, some DC CPUs like high, some low and some close to stock VCCIN. So it's worth trying from 1.5V (too low) all the way to about 2.1V (too high), I'd say. Regarding VRING, I'd leave it at stock (Or even set it manually to 1.05V or 1.1V and leave it there with the cache at x40) until I finished my core overclock and then mess with the cache speeds independently. Or not at all, as the performance gained is far from substantial and the instabilities caused sometimes are annoying and hard to diagnose.

I tweak only where I have to. With my 4770k I absolutely had to up vccsa from auto. With the 4790k for 47/44 I basically only had to twiddle vccin, vi, vring and memory stuff to OC memory.

Sounds like your chip is similar to mine. With everything else at stock voltages, i could only do 4.7@1.32v. Will try out you settings to se if i can get higher
