Z790A Rog Strix undervolt setting?

[BIGWORM]

Hello,

I recently build a new system using the Asus Z790a Rog Strix. I am trying to lower my CPU temps in cinebench R32. At times I see it hit 84C.  Ive watched a lot of videos of under volting the vcore, but my BIOS does not show what there's shows. I then noticed that some people suggested lowering AC and LL settings or something like that.

I am looking for guidence on what to change in the latest bios to lower my CPU temps under full load. Using the latest BIOS. 

System specs:

Corsair 4000X Case

Asus Z790a Rog Strix

Intel I9 13900k

Corsair 32GB DDR5-6400

Nvidia RTX 4090

Hello,

Try setting SVID Behaviour to Best Case underneath Extreme Tweaker. LLC is set to level 3 by default, which is fine. 84C in CR32 is fairly typical for an undelidded CPU as it's a high current workload. It's also worth investing in a contact frame as this can help with even mounting pressure.

Thank you for the reply. So I should change SVID behavior to BEST case. Ok, I have seen that setting sand can do that.  And yes my LLC set to auto is showing a 3 under it.

I do have a contact frame. I have the thermalright one. That was scary to install. No one talks about making sure you dont crank down on the bolts too much, thus damaging your trace lines in the PCB. 

I will try the SVID thing to best case. And see what happens. What about those AC LL setings people keep talking about?

I know the Thermal Grizzly one has the correct torque information. A good rule of thumb [no pun intended, promise] if not having a torque driver handy is to tighten as much as you can with your finger and thumb, and then turn a further 90 degrees. Setting the SVID behaviour to best case is the same as adjusting the AC loadline.

Yes I saw their solution. Jays2cents reviewed them both and found that the TG solution floated over the CPU where as the TL solution was better fit since it touched the MB and had pads where it would touch. TG's installation is much more technical as you can tight it too much and cause CPU issue. The TL solution you tighten until it stops. The pads on the bottom of it, keep it from smashing your MB trace lines and smashing the CPU in too deep. Based on his review, I went with the TL solution.
