My gigabyte motherboard - H170M-D3H GMS, supports up to 64 GB of DR4 2133. . I had (2) DR4 8G 2133 memory modules installed into slot 1 & 3. Unable to purchase the same speed, I installed (2) DR4 8G 2666 sticks into slots 1 & 3 and installed the DR4 2133 into slots 2 & 4. Upon restarting my PC, I find that only 16 G are showing. I'm running win 10 64 bit.
All 4 memory modules are Kingston Hyper X . Can someone tell me how to correct this?
