I have recently upgraded my homeserver to Lenovo M90S Gen4 SFF with i5-13600.It has a Q670 chipset. I ordered it with 16 GB of RAM and it came with a Samsung DDR5 UDIMM module with an advertised speed if 5600MT.In the bios hardware summary I could see this module working at 4400MT(assuming its chipset limit) Then I got a 64GB DDR5 kit of Patriot viper of advertised speed of 5600 MT. After installing them, I am only getting 2000MT speed in the BIOS. Unfortunately, there are no option to control the RAM configuration in the BIOS of Lenovo M90S. Is there a way by which I get at least 4400MTs from all 80GB RAM? If not what is the better tradeoff? 64GB at 4400MT or 80GB at 2000MT? I will be using this machine as Proxmox node.
