I have a cyber power that I bought from Sam’s club it’s about 1.5 years old. Motherboard is a ASUS PrimeB550 AC-HES. I am trying to upgrade the RAM it originally came with 2X8 3200 16-20-20-40. I bought 4X16 3200 16-20-30-38. I installed the new RAM booted the PC and got blank screen although the pc was running. So I removed all but one stick and tested it singularly through all 4 slots, it booted every time and recognized the RAM (although at a 2133 speed not 3200). I then tested each individual stick of RAM and they all worked fine. I tested 2 at a time 3 at a time etc all tested fine. It’s whenever I install the 4th stick I get a problem. It doesn’t matter which slot I leave empty 3 will work 4 will not.

So I grabbed the original RAM and put one of them in the empty slot. Booted up no problem. System recognized \~58GB of RAM.

I’ve updated BIOS, reset BIOS, turned off the profiles, turned on the profiles, and I still have nothing.

Any ideas? Thanks in advance.
