I recently bought an Asrock 4X4 BOX-4800U.

According to the specs, it should be compatible with any 64GByte kit of two DDR4 SO-DIMMs up to 3200Mhz.

I bought the CMSX64GX4M2A2933C19, which also is supposed to be compatible with the aforementioned APU.

When I use the memory kit or any one of the two modules in my Asrock, memtest86 reports almost the whole memory as erroneous and I cannot get the system to boot from any of my USB sticks or from the Linux I installed to the SSD. All errors lead to memory errors ('Checksum failed', 'could not access root', etc.).

When I try different RAM in the ASrock (I have an 8GByte Samsung Stick laying around), I can get Linux to boot. When I try the RAM kit in a different Laptop, I can get Linux to boot. In both scenarios, I can also succesfully test the system with memtest86.

That means:

Only when I put the memory kit into the asrock, I get memory errors galore and memtest86 fails miserably.

Does anyone have an idea what I could do?

The asrock bios does not allow me to change any memory settings, no timings, no voltage, no profiles. I also updated to bios to the latest version to no avail. I disabled Cool&Quiet and also tried many other Bios options. It always fails.]]> Sat, 10 Apr 2021 18:56:47 +0000 https://forum.asrock.com/forum_posts.asp?TID=18596&PID=85318&title=asrock-4x4-box4800u-incompatible-to-my-memory#85318
