Can these be used on a Z690 motherboard?

Kevin Crooks

Really awesome write up! I tried these same settings with same mobo, 13900k, and 16gb x 2 gskill 7200 Hynix a sticks. Still not stable at 7200 but closer than before. 6800 is max I can get stable. What can I change to help maybe get this stable?

Kevin Crooks

Gotcha. I got all 4 set to 120. What’s considered safe on those voltages?

Kevin Crooks

Good deal. I’ll slowly start upping them to see if I can get it stable. Thanks again for all you do

HanVengyy

is it nessesery to mess with pll voltages is that important (can they be on auto)
