Hello,
Few days ago I bought pair of DDR4 RAM sticks for my Extreme 4 Z390 MoBo. So far I was using 2x16GB Predator (Kingstone) 2666MHz CL13. No issue with them, therefore I looked for exact the same product and I found it. Unfortunately I cannot use them, and here is how it looks:
1) UEFI recognizes 64GB or RAM and starts without any warning beeps
2) System is able to load GRUB loader - I can do selection or change parameters there
3) After making a choice, system freezes, no matter if I'm booting from local disks of external devices
I tried different combination of memory sticks and slots - any presence of new RAM is responsible for freezing, old RAM works flawless.
RAMs are on hardware compatibility list for this MoBo.
Any idea what can I check/test/change in MoBo configuration?
-------------
Regards
Maciek

You must have a matched set from the start. One cannot add ram manufactured at a later date. In most cases it will be different. The individual chip can have different characteristics .

Try to turn off XMP/OC settings and go to the bottom of RAM OC settings page to turn Fast MRC off and AsRock optimizations on. Save & reboot. If still no luck ??turn the XMP profile on and reboot. Clean your MoBo RAM slots ??high frequency acts like a magnet for any kind of dust. Clean DDR contacts with isopropyl. Repeat XMP off/on reboot steps. Leave only a new ones RAMs plugged into A2 and B2 slots to check how they?™re.
