I upgraded my workstation system from 2 to 4 RAM Sticks (16 GB Corsair Vengeance DDR4-3000 DIMM CL16 Dual Kit). Both RAM kits are from the same vendor and work smoothly together on Ubuntu 20 (LTS version).
In BIOS, all 4 Sticks get detected. I use the default speed of 2133 MHz and did not do any overclocking, neither on CPU nor RAM.
However, when I boot to Windows (10, Education), only 16 of 32 GB are usable while the remaining 16 GB are hardware reserved.
Both Windows and Ubuntu are located on the same SSD hard drive (ca. 250 GB storage for each system).
Did you encounter similar issues when adding RAM to Windows 10? Since the RAM is working on Ubuntu 20, I assume that the hardware side should be ok.
