specs:
MOBO: Asrock Z270 PRO4 - driver up to date
CPU: i7 7700k all cores 4.4ghz
Cooler: Be quiet! Dark Rock Pro 4
GPU: GTX 1060 OC
RAM: Kingston Hyperx fury 2x8 2133mhz
PSU: Corsair 550w
Long version:
I need some assistance from you folks about my overclocking. i got this CPU i would say a year and a half ago and I always intended to overclock but i never really needed it until now. In the past I tried to overclock but my PC stopped booting and with hours of troubleshooting it finally booted and after that i stopped messing with the bios for a while. However I've been looking at a lot more threads and videos to help me with overclocking but i still don't have a definitive answer on how to overclock. I don't really want to exactly copy what someone said in a thread and or video as every motherboard and CPU acts differently. with everything at default my voltage seemed to jump between 1.3v and 1.35v on H/W monitor when stressing the system without any overclocking. This seemed to be really high especially at stock so i updated the bios and set the CPU voltage at a fixed-mode at 1.27v with XMP off. I then wanted to boost the cores a bit so I set CPU ration to all core at 4.4ghz. I also set the LLC to level 2. I want to try and get this higher once i know what i'm doing.
My LLC goes from level 1 which as at the top down to level 4. I know LLC helps to lower or raise voltage when needed but I don't know what the levels mean for example i don't know what a stable voltage should look like. when i set voltage to 1.27v my LLC seems to keep my voltage between 1.245 and 1.255v when on full load. when i'm just on windows however my voltage seems to spike to 1.29v for a bit.
furthermore when i decreased my voltage from 1.27 down to 1.25 but voltage on H/W monitor seemed to be exactly the same but my temps were lower? that got me thinking that its not actually showing the correct voltage if i'm not mistaken or if its got to do with the LLC. My bios also has a boot performance mode. I set mine to max non-turbo performance with the highest being 'turbo performance' i don't think this matters as I've already set my core ratio to all core but i leave it be. Lastly I don't know what to set mine CPU cache Ratio again this is just left at Auto as i'm not sure what to set it to. sorry if this all seems confusing but i just have a lot of questions
Short version:
stock speeds voltage on bios is at 1.3v and jumps to 1.35v which seems to be high for stock with LLC auto.
set all cores to 4.4ghz fixed mode 1.27v set LLC to level 2 but not sure what to put LLC exactly on. (XMP off)
CPU cache ration is set to auto no idea what to do with that
at 1.27v / LLC 2 my voltage on 100% CPU load is between 1.245 and 1.255. however when im just on windows it sometimes spikes to 1.29v? when nothing is running.
Decreased voltage to 1.25v and H/W monitor detects the same voltage output, even for 1.27v but with lower temps - there is where i think LLC is confusing me
boot performance mode? don't know if its needed as I've already set all cores to 4.4ghz constant.
