8700k MCE Issue

Hello, 

 

I overclocked to 5Ghz using 1.35v then I experienced 80c in game so I thought I would try and lower the temps. I went into the bios and tried Asus Multicore Enhancement. I disabled it and booted into windows and the vcore showed around 1.52v!

 

What the hell happened? Anyone have any idea what I did wrong? I tried to lower the temps not destroy the CPU!

 

Thanks a lot for any help...

When you disable that the mobo most likely also revert your voltage settings. These auto-tools are dumb..

Revert them to 1.52v?

are you looking at the VCORE or VID?

 

turn off MCE when overclocking. and set voltages manually to 1.35v. check if MCE changed the voltage settings.

100% sure. I was hoping it was a bug or something. But scared the shit out of me. I can't believe it ran that high vcore.

Definitely was looking at vcore in hw monitor 

use quote post.

 

revert back to your old 5ghz settngs and disable MCE. and lower your voltages from there.

MCE is the Auto-OC function that heavily overcompensates on voltage most of the time... it varies from board to board.

I just don't understand. I thought it would reduce temps! I had svid behaviour set to best case scenario. For my 5ghz oc I had 1.35v llc level 6. I am wondering if that could have made the stock intel setting (mce disabled) go to 1.52v because of the llc?

Turn off MCE, turn off CPU SVU support and ajust load-line calibration accordingly.

But having it enabled in the first place kept my voltage at 1.35v and disabled 1.52v. The overclock was completely stable I was just trying to lower load temps. There's no way I am changing it back now!

I dont know how Asus's software works since I havent touched their overclockable mobo myself, but if your current settings only work with MCE enabled then keep it there. My idea is that you opt for 'auto' voltage right from the start when you start overclocking, which overcompensates voltage as you increase the clock speed (which is perfectly normal since mobos have to accommodate chips of the worst silicon quality). MCE is the one that limits the voltage.

ASUS Multicore Enhancement: Setting to Auto applies the Turbo ratio to all cores. Setting to Disabled uses Intel Turbo policies. These options are only effective at stock CPU settings. When a manual overclock is applied, the Turbo ratios are assigned according to the CPU Core Ratio settings.

I read this on the kaby lake overclocking guide. I still don't understand how this applies to voltage as I already set my voltage to max 1.35v

Also, says they are only effective at stock which doesn't seem to be the case in my situation

I used 5GHz mode from ASUS BIOS on my i5 8600k. It set voltage to 1,45V ... needless to say I disabled it and went with manual OC like I was planning from the beginning. Was just interested what settings they used for that "5GHz Try Me" profile xD

My 5ghz OC was already tuned I just wanted to see what disabled multi core enhancement did. Turns out you should never disable that if you overclock on adaptive voltage. I think that's what gave me 1.52v vcore reading. Not happy.
