OC'ing 7600k on msi z170

CivilDrone · 31 Jul 2019 at 06:43

Morning
Playing around with core multiplayer and volts is pretty straight forward
How about the options such as CPU SA and IO voltage? Also there is ST PLL and PCH voltage options
Should I be paying attention to those to?
Another strange thing is ram which is 3000mhz doesn't boot on xmp, when lowered down to 2800 seems fine
Last bios update was a while back, assuming that might be it
After playing around a little was able to get 5ghz on 1.35v without playing around with the rest of the above mentioned volts
Any help or advise on this or overclocking in general?
Cheers

on the skylake/kirbylake cpu's all you need to do is change voltage and multipliers.

i played with my CPU's for months changing ever option under the sun and never got any better overclock, in some case is was lower or run hotter.
my CPU is 4.8Ghx @ 1.375

managed to get 4.9Ghz on 1.35, not sure if its safe to go for higher volts as it goes red and looks scary

With a delid and liquid metal applied temps get to 75-80ish which isn't too bad, thinking of trying h100i v2 or cryorig a40 and perhaps then push volts slightly
In regards to C-state and such, do you run yours at full OC speed or dynamic mode?
Couldn't get ram to run at 3000Mhz and set it to 2800 with 1.2v I believe
Ran memtest with no errors

Just swapped one of the ram stick to position 3 and XMP works
Was not aware of limitations due to placement of the sticks 3-4 now, works a treat

You want Cstate enabled. No point running at full speeds all the time. Do you have vcore set to offset or fixed. You may need a little more voltage with you switch to offset.

As for you need more vcore to go over 4.9ghz there is no point. 1.35v is good and I would stop there and extra 100mhz is nothing.

What cooler are you running now? I am not 100% but I think mine hit 80c on a low profile cooler, it was delidded.

Are they in the right channels? They should be in A1/b1 or a2/b2

I've had a2/b2 and xmp didn't work, now running b1/b2 and everything works
not sure how stupid this sounds but ram timings, I am able to set 15/18/16/28 instead of stock 16/19/19/38 does that make any difference?
Thinking the same, leaving [email protected]
Have a fixed offset, haven't really played with that option just yet
cooler is: Alpenfohn Matterhorn black with 2 apache black fans AK-FN062

The lower ram setting will be a little faster. Personally I keep xmp setting, put ram voltage to 1.4v and start bumping up the speed most ram will go one or two bumps up you should get upto 3500/3600mhz

Before playing with ram and thinks like that get vcore into adaptive/offset. It will take some playing to get it stable you may fine you need a little more voltage but it will run cooler.

Find the option for llc, load line calibration and set up to one under max setting. This will help with voltage drop under loan when you set adaptive voltage
