I’ve just bought a 13900 non-k cpu and z790 carbon wifi with 32gb Corsair dominator 7200 mhz ram.
I was thinking of the settings for the cpu and undervolting .
Should I set cpu voltage to 1.3v and leave everything on auto and load xmp?
 
A quick update. Set 13900 voltage to 1.25v and xmp profile boots but not stable in gaming
I’ve lowered the xmp speed from 7200 to 7000mhz and it’s fine.
However shall I try xmp profile and up the sa voltage to 1.25v?
Using latest bios, thanks
 
I don't know about RaptorLake but Alderlake (12000 series) all non K series cpu's were voltage locked and you can't change things like SA voltage. You can change the settings in the bios but they are hard locked and once you boot the pc the voltage is the same as before. I wouldn't have got the 12600 non K if I knew about this.
 
You can try CPU lite-load instead of manual undervolting if you like, It's a bit more user freindly if you're not concerned with hardcore tweaking.
Bascically, the lower the lite-load number, the more under-volted the CPU will be. It defaults to 9 I believe & I put it on 7.
Not because that's the lowest it might be able to do, but because I'm too lazy to do comprehensive stability testing & it still helped with temps. Not experienced any instability in games or rendering/ compiling etc etc.

Thanks for your replies everyone
I’ve managed to get my xmp profile stable by setting SA voltage to 1.2 and I’ve set the cpu voltage to 1.25 and left everything else on auto.
However when I checked hwmonitor SA voltage is still on auto it seems so think ure right about hard locked SA setting
Maybe it’s lowering my cpu voltage that has helped stabilise the xmp profile.
I’m thankful as I’m def stable compared to before with zero crashes on bf 2042 ( a brilliant memory stability tester!).

My cinebench score is rather low-18k
Everything is on automatic apart of v core which is set to 1.25v
Max power consumption for cpu is 170w and cooler type in bios is set to water cooling at 400w and boost to all core.
Not sure why it’s so low.

may i ask what you tested the ram in? ive had the carbon for a few months, i wouldnt run xmp , as i would tune, but 7200 on my g.skill doesnt work without errors, no matter what ive tried, xmp on or off and many different timings and voltages applied.
 
I’ve left everything on default and SA voltage can’t be altered as I have a 13700 non k chip
I have noticed slight instability with the bios that came out last week and have had to manually set speed to 7000 mhz and all is stable
Haven’t used any mem testing software as my litmus test is gaming esp bf 2042 which crashes on any memory flakiness
So far no crashes for a week and I can live with that.

ah its just you said you set sa voltage to 1.200
xmp wise nothing over 6800 works for myself and many others, and i have spent months tuning
Try using occt and test yor ram, i get what you mean about gaming, after a few hours gaming what im playing will crash due to ram, then i test and its no longer stable
