Thanks.
“Up to 32GB DDR4-3200” this might not be accurate because it does support 32GB x2 64GB. And I do have 64 installed at the moment.
Also inxi -m reports:
Array-1: capacity: 64 GiB slots: 2 modules: 2 EC: None
even when only 32GB installed.
When I installed 32GB 3600MHz spd 2666, it runs at 2666.
When I installed 16GB 4000MHz spd 2133, it runs at 2133.
I found this old thread:
it mentions
“Only you will make change in “SaSetup” GUID 72C5E28C-7783-43A1-8767-FAD73FCCAFA4 and NOT in “Setup”
Go to offset >> 0x134
^^ Change 00 to 02 for XMP1, or 03 for XMP2”
is it possible to do the same say change the memory profile from 00 to 03 to enable XMP2?
