Also, I notice ridiculously high VCore spikes during benchmark run (>1.45V) which causes CPU to boil (95-97°C)

Also, on ASUS boards, i saw vcore bursts caused by Asus multicore enchantments. This is an extra manufacturer boost, that is enabled at stock, and can boost a 13900K up to 6GHz... at stock
On the MSI boards, it's called MSI enhanced boost ( or something similar. it should be under cpu advanced settings, right below Intel extreme boost 3.0 setting). Disabling that might fix your vcore going crazy.

Will give a try, @TENPATROL! Also, on CB R20 I have no issues, effective clock is stable and I have 10200+ pts...

undervoltage control in cpu setting

Would you be so kind to point me where in bios I can find that option?

This helped with VCore spikes indeed, keeping it max at 1.25-1.27V, however I still have quite low value in CB R23 (now under 21k). To my surprise, CB R20 shows me that Effective Frequencies for both P/e_cores are maintained during the test and the score is similar to what I have seen from reviews... Can this be issue with CB R23 only?

You're very welcome

hi
i planning pair z690-a ddr4 with intel 13500

At this stage of bios updates, can you confirm if i can undervolting the cpu with adaptive+offset / cpu lite load / power limit without performance drop ?

thanks

According to chart in this post, that combination should have the option where you can set IA CEP to Disable.

Update: that thread has new post today pointing out that undervolted 13500 works with MSI Z690 (without performance drop) but may not expose any BIOS setting for IA CEP needing change.
