Imprezzion MPG Pro Carbon has a pretty decent VRM lay-out performance wise but the cooling is pretty lackluster. The Gaming X has maybe the better VRM but the BIOS and board features are worse. I'd take the Pro Carbon and put a fan above the VRM and call it a day.

Sacerdus Hello guys, someone know if one of this boards can handle with a 9900k+OC? They are the cheapest on sale here.

Maestro1337 Are the VRMs in the extreme4 z370 good?

ronaldoz The VRM of my MSI Z370 Pro Gaming Carbon was getting 108C after some minutes of testing with Prime 95 SmallFFT (default settings with AVX)... I decided to stop the test.. and find out how that could happen.
I've put a 140mm fan (don't have another fan at the moment) in front of the VRM's and it is steady at 74C when performing the same test.
With SmallFFT 1344K it is even lower, like 63C maybe.
This is with 8700K / 1.30v

With the fan, the VRM temps are not a issue anymore.
The CPU is around the same temps. With heavy stress testing a bit lower then the VRM. (like 3C)

Lao Tzu Hi, recently buy a 9900KF and have an Asus Board Z370 MAXIMUS X CODE, and VRM are quite good, can OC to 5.1GHZ with 1.260v (idle 37°C, 85°C Full Stress, 40-60 in games) Cooler CPU AIO 240mm, without problem, need 1.325v to reach 5.2GHz but i need a better cooling solution to down temps, VRM Temps 52°C, but better VRM than Z390 if looking some board to buy...

ronaldoz I also gonna read the thread more, but could anyone suggest a cooling solution for the VRM's? I'm getting 96C when using Prime 95 v29.8 Small FFT (default settings) without AVX. With AVX, the CPU will run at 37x after a while. At the moment I got a 280mm radiator in the front, only having 2 x 140 fans pushing. So I will get 2 x 140 to also pull. Will that help much or should I have active cooling at the VRM?

Thank you!

Different vrms and model of boards have different hole spacing.
Oh whoops MSI Z390 Godlike

Hi thanks, that would make sense.
I was running with speedshift mode enabled in BIOS and windows set to autonomouse mode. If I just disable autonomous mode in Windows, VR OUT lowers at idle as I thought it should. It is a difference between > 1,25v avg. with autonomous enabled, and .725 autonomous disabled. So I don't know if the OS can tell the chip to no longer use speedshift when I disable autonomouse mode.
