GB Z590 AORUS XTREME + 10900K cant change VCSSA Voltage!

[Mappi75]

Hello,

i got a GB Z590 AORUS XTREME (F7) + 10900K and want to lower the voltages for the RAM because xmp set too high voltages.

The problem is: i can change only the VCCIO voltage - the VCCSA voltage still remains on 1,4V+

CPU: 10900K
Cooler: Noctua NH-U12A
RAM: tried different Kits like 32GB G.Skill 3800 CL14 / 4400 CL17 / 4266 CL17 kits..
PSU: Corsair AX1600i
2x Samsung 970 Pro 1TB + 3x EVO 4TB.

I installed Bios F6 which change nothing / resetting bios / unplug power cable / switch bios chip


Thanks for helping.

Hello i tested now a 11900k and with this cpu i can change the vcssa voltage.

Its a problem with this mobo and 10900K combo - which should work.

No problems with the Asus Apex XIII (z590) & MSI Godlike (z590) with 10900K cpu.
