Question Problem OC/XMP above 2133 Patriot Viper DDR4 4 x 8GB 4400MHz with 13900k no OC

[eliau81]

Hi
can't put XMP or nothing else above 2133
no voltage chenge all on auto
CPU 13900K with no OC
MB MSI Z690 DDR4 EDGE with new bios 1E0
i get OC failure and go back to bios
I can post with no XMP only with 2133Mtps
I tested other rams like g.skiil 4000Mtp and same issue could not even go to 2400Mtpa

Please im getting nuts...

The CPU-World.com web site shows "Supported memory: DDR4-3200, DDR5-5600" for the 13900K so perhaps 4400MT/s DDR4 is not possible without manual tweaking in the BIOS.

Try XMP overclocking with only two DIMMs installed instead of four.

High XMP speeds with 4 DIMMS fitted can be more difficult to achieve than 2 DIMMs, due to the additional load on the Integrated Memory Controller with all four slots filled.

13th Gen's issue is that you can get to high frequencies if you work with 2 sticks of ram. If you want to work with 4 sticks of ram, you need to set your expectations to lower frequencies.

You stated being on BIOS version 1E0. if you flashed the BIOS to the latest version recently, clear the CMOS and then try with X.M.P. If that doesn't work, try and manually set the frequency and voltage in BIOS manually.

Did clear CMOS
voltage
SA AGENT 1.2 - 1.25
VIQQD - 1.35 -1.375
DRM VOLTAGE 1.45 - 1.55
nothing works
Also it's taking to long to post like 3-4 min every power on
The boot to windows in normal but power on and post is very long

Test with one stick of ram in slot A2.
If no help try a different stick of ram.

Can MSI center app be related to this problem
Maybe I tried to tune something with the app ...
I can't recall

MSI Center gets mixed reviews. You could try uninstalling it, or if you can't get rid of it, try a fresh install of Windows on a new SSD.
