I bought b560m msi mag mortar board and AX4U360016G18A-DT60 RAM sticks. It worked badly with XMP profile (memtest86 plenty of errors). I thought it's because RAM is bad so I sent it back to shop (it's still in progress). Today I tried to test this mobo with CMH32GX4M2E3200C16 sticks; it worked even worse because I could not even boot into windows. Without xmp profile on 2100 MHz speed memtest86 is clean. I managed to return money for last sticks. I called msi hotline and they said that if memory is not in the approved list it wont work on xmp speed. The thing is, there is AX4U3600316G18A-DT60 in approved ram section and I could not find any difference with AX4U360016G18A-DT60.
So now I am in doubt what causes faults here?
- RAM of 3600 works better than RAM with 3200 (while not well enough, just better)
- 11600 supports 3200 speed only according to specs; but in reviews it is tested up to 4000
Now I dont have any RAM sticks to test. Can CPU make such a mess ?
Still, the processor's warranted maximum memory speed is 3200, not 3600 and not 4000. Intel only warrants what it tests and that is a maximum of 3200. As I said, it is the motherboard (and its BIOS) that usually determines the maximum you will achieve.
Hope this helps,
