If you use ASUS X299 motherboard (confirmed on my X299 TUF MK1) don't update to BIOS Version 1704. It disabled BIOS downgrade for me, which isnt much of an issue, but ASUS BIOSes have critical flaw.
I've found out that most BIOSes don't actually let you control voltage of your CPU. Early BIOSes would even report the voltage incorrectly, for example: if i set my CPU to 4.8Ghz and my Vcore to 1.130V it would boot, and be 100% stable. All monitoring software would show approx the same voltage I applied in BIOS. This was obviously false, my guess is that voltage was about 1.3V.
Later BIOS revisions fixed the incorrect Vcore readout(in a way that there is at least some control) but the actual voltage is still "unknown". There is only one BIOS which actually lets you control Vcore and that is Version 1503 and only in manual Vcore mode and disabled downclocking (sync all cores → [your desired CPU multiplier] → manual → [your manual voltage]).
In case you are already on BIOS 1704 and decide to downgrade, then you'll need to use ASUS BIOS Flashback (which can be kinda risky). It did work and my temperatures went back to "normal".
Feel free to test it for yourself if you have TUF X299 MK1: (Had to upload it to mega.nz because apperently 21MB is "too large") - contains now removed BIOS 1602, original 1503 and 1704.
I assume the situation on board from the same line-up will be identical (at least on X299-A Prime, TUF X299 MK2...). Feel free to test it for yourself, you might get some extra performance out of your CPU or cooler temps.
It would be great if mutliple people could confirm this, just to be sure, as one "test sample" isnt very scientific.
Note: Using Ai Suite overclocking makes the BIOS 1503 act like other BIOSes → BIOS reflash is required to get the voltage control back.
My results:
Version 1503
Version 1704 (the lower score is because i had steam running in background, as far as i can tell the BIOS versions dont effect score)
Both were ran at:
BCLK: 100.1
Multiplier: 47x (Sync All Cores)
Memory: 3600Mhz 18-19-19-34 T1 tRFC 279
Memory voltage: 1.25V
System agent voltage: 0.930V
CPU input voltage: 1.670V
CPU Current Capability: 140%
LLC: Level 2
Vcore: 1.205V
Uncore offset: +0.150V
Mesh multiplier: 32x
Mesh Voltage: 1.010V
Feel free to replicate my settings.
