Yes, you can use XMP/OC for 2DDR kits with the same number part but from different chip manufacturers.
Yes, you can use XMP/OC for 2DDR kits with the same number part but from different chip manufacturers.
Yes, you can apply XMP to kits containing two modules each from different manufacturers. You can also set varying timings for each kit while keeping the same number of parts, capacity, and CL.
XMP is fetched from RAM at slot A1. Timing settings can be adjusted manually.
It’s better to use the vendor’s settings (Corsair) since they provide consistent timing for both kits. The Ryzen DRAM calculator may show variations based on the specific chip in each module.
Results may be uncertain; apply more relaxed timing for all four, just to be cautious.
