FlanK3r - Core i9 9900K @ 5906MHz - 2624 cb Cinebench - R15

we had a similar ES one, CB around -150, however 6Ghz is not worth spending LN2 on...

5.9 with ln2 and Low cb you need to sell it immediately ?

I sold one, first one was worse than this...No I need money for new Ryzen, so I must be "fine" with this CB guy :). At least, 5 GHz AIO is stable for 30minutes (without AVX). MAx R15 5150 MHz on AIO.

Don’t worry. I had trouble with my 6.8g R15/7.2g Pi chip with CB but got around it after 20L of LN2 to find the right combination  of voltages. 

key was booting low pll termination, not over 1.6v then set eventual to 1.68v. RSVD did not work for me on that chip and only gave a 00 code every time I used it. 

1.1v internal pll voltage

core pll 2.35v

cpu standby 1.6v

dmi 1.5v but increase in OS for stability, 1.85v was fine for me, but didn’t like booting higher than 1.5-1.6v (again would 00 code)

pll bandwidth 3 seemed best also

Thank you for tip, I will try it. And yes, is it as u wrote. Classic values values doesn't helped me. It was playing with different bandwidths, pll core and termination voltages to change CB. RSVD also not worked fine in my case.

Since Apex IX the profile LN2 settings didnt work with me (speaking only about cold volts). Had to look for advice from RTsurfer or find some stable values for fullpot just like Karta told you. Next time will be better for sure :D.

it depends on your cpu you need rsvd or not, some 9900k dont need it to be able to run fullpot. but according to my experience rsvd needs lower temps like -135C at least to start working, unless you just receive 00. anyway this cpu seems to be a real potato Michal, sell it fast and save money for 16 core AM4 chip :D

Bála, but fór daily usage Is better than first one, the first was ale to do 4950MHz R15, not more ?
