i9 12900k temps

this is mine at 49 core @ 1.25v with 40 e cores and 40 cache, LLC level 4 and 140% cpu capability. Maintains a constant 4900hz

Yes you can manually set voltage on these boards. Set LLC in digi vrm to 4 or 6, set current capability to 140%. When running a benchmark have core temp and cpuz open so you can check if its downclocking. So if its set at 4900hz does it remain there throughout. while you are testing and trouble shooting disable C-states in the advanced cpu tab and when in windows go to control panel type power options and select the performance tab instead of balanced tis will run everything at full so worse case scenario. you can change back after. out of curiosity what clocks are you running and at what voltage and what was your power draw??

When I do this and manually set the vcore to 1.250 I get a massive reduction in performance

set 49 core @1.25v 40 e cores 40 cache, LLC 4, 140% current run cinebench 23, keep a close eye on temps, (core temp) and clock speeds, if you are nearing temp limit it will downclock. XTU app is quite good for testing as it show if you are thermal throttling etc

a screen shot would help
 
hang on a sec, boot to windows, top left, click advanced benchmark then run, it should run once and give you a score, it should only do 1 pass

******** turn minimum test duration off *********

wow ok, you know its going to be something really simple!!! only one more thing i can suggest and thats go into cpu power management in bios and increase all power limits to max, theres 2 at 4096, 1 at 511amps and another around 480( this one drop down box) others just set just press any number 5 times and it will go to max value

It didnt make any difference. Now I have taken the vcore off manual and changed it to offset 0.08 and my score goes up to 27415 but so do my temps with 4 cores hitting 98c, so basically back where I started. very strange. PSU draw is now 252.
 
So I have set the offset to 0.1100.
Cinebench score is 24619k with 1.288 vcore and 233w draw.
Highest core temps are is 93c.

All in all I am happy with that. Will I see any real world performance difference gaming from 27k to 24k on Cinebench?
