As the title says, will it fix the XMP profiles for having 4 DDR slots in use?
Some 4 DIMM configs have finally appeared on the
Strix Z790-E Memory QVL. There were no supported 4 DIMM configs listed not so long ago. Pay particular attention to the "socket support" column on the QVL; "1,2" is single or 2 DIMM configs, and "1,2,4" is also 4 DIMM configs. Is your memory listed on there as "1,2,4"?
The BIOS may help a little, especially since it says it improves DRAM compatibility. It's not clear if the QVL now lists some 4 DIMM configs because of BIOS improvements, or because they have done additional testing and found some DIMMs which work.
N.B. The fastest memory speeds generally just do not work in 4 DIMM configs, unless you are really lucky. You can't have both capacity and speed maxed out. Currently, the fastest 2 DIMM config on the QVL is DDR5-6800 CL32, and the fastest 4 DIMM config is DDR5-6200 CL40 or DDR5-6000 CL32. It was also like that on DDR4, the fastest easy 4 DIMM DDR4 config was roughly DDR4-3600 CL16, despite much faster DIMMs floating around.
