Who has successfully ran xmp on Z390 with 4000+ MHZ ram

I have seen lots of threads about xmp profiles not working on 3733mhz + on XMP profile without any adjustments. So I would like to see who has successfully ran their xmp profile on 4000+ MHZ without any adjustments at all.

thanks

I ran 4000MHz on a Gene with a couple of 9900KSs...XMP and up and running...

Most other times I had to adjust something

Reading this forum for years it seems corsair sticks run smoother in general with xmp than gskill.

+1 you do get much better results tweaking.

I'v tried most of the 2x8GB Extreme Tweaker\DRAM Memory Presets in 1401 BIOS with the Corsair LPX 4600 kit.

Few days ago started running 1502 BIOS, and 2x16GB Samsung Double-Side modules. F4-3200C14D-32GTZSK kit,..

running @ 1.35V they will do 3733MHz,.. this weekend going to bump up the voltage, would like to see 4000MHz +
