Switching to a better Mobo help with lowering Ryzen 9 3900x CPU temps?

[Cowboystrekk]

I just tested this on my 3600.

1.2v 4.2Ghz 3743 R20 56celcius lol that's a 10 deg cooldown for a 100mhz all core overclock with less voltage..... lol.

1.2v 4.250Ghz 3779 57C

1.2v 4.3Ghz 3816 58C

Crashed at 4.35 1.2v

1.25v 4.35Ghz 3879 61C

1.25v 4.4Ghz 3915 63C

Utterly mental.

Seems you have a 3600 golden sample. Mine needs 1.25V to be stable at 4.1GHz. Good for you

I think I just got lucky, I didn't even see the box for the CPU as I got the motherboard CPU and ram as a bundle.

I did manage 4.55Ghz at 1.425v a bit crazy and there were no real benefits to those speeds as the temps were creeping into the lower throttle area. It did score 4037 in R20 with no tweaks other than ram timings. So I reckon I could add 100+ more to the score if I cared about optimising the overclock, All CPU features were running on the run, and windows was just as is steam ect running in the background.

It is a newer sample, I only got it in April, so perhaps chiplet yields have matured.

My 3900x runs wayyyy cooler on the stock heatsink compared to the OP. Undervolting does help because some boards tend to run the cpu at higher voltage than necessary (asus, fingers at you).

I installed the stock AMD prism cooler and the temps are now in the 50's (celsius) on idle.

Mine runs around 4-5 degrees cooler, idling around 42C and I'm in 27C degrees room. Case is Cooler Master 500M.

With light tasks running (firing up adobe PS, have a 4k youtube running on the background)

Unfortunately it turns out 4 CPU pins were bent and 3 out of the 4 Motherboard RAM slots are unstable (sometimes PC does not boot, even with XMP disabled. Issue does not occur when installed on other motherboard). The CPU pins have been fixed and tested by the PC technician. I will have to purchase a new motherboard, the MSI X570 Tomahawk WiFI, and see how the temps compare. Thank you for all the assistance.
