Hi people,
I have problem to install my new 32GB RAM in my setup (see specs below). My system will bootloop (no screen signal and then reboot) when i plug in my new ram.

I did this:

Use my 8GB to start system
I got the latest BIOS to date.
Reset BIOS (with CMOS jumper)
Mounted 32GB stick in RAM slot DDR4_A1 also tried DDR4_B1
= Bootloop

then..

"Load XMP Setting" to "XMP 2.0 Profile 1"
Set "DRAM Frequency" to "DDR4-2400"
Save Exit
Change to 32GB RAM
= Bootloop

What options left? Manual config maybe?
When in "XMP 2.0 Profile 1" mode i can enter my settings manual in "DRAM Timing Configuration" (link to picture https://photos.app.goo.gl/l5MhX7nUWOBrrX9l2" rel="nofollow - OC Tweaker\DRAM Timing configuration ) but i am not sure what to enter here..

How to setup https://photos.app.goo.gl/l5MhX7nUWOBrrX9l2" rel="nofollow - OC Tweaker\DRAM Timing configuration with this information?
Kingston specs:

CL(IDD) 17

Row Cycle Time (tRCmin) 46.16ns(min.)

Refresh to Active/Refresh Command Time 1x mode (tRFCmin) 350ns (min.)

Row Active Time (tRASmin) 32.00ns(min.)

Nope.

This stick will not work.

You want Unbuffered ECC, not Registered ECC.
