Hello L1T!
I was having an issue with the RAM in my workstation. It will only use the memory in 3 out of the 4 available DIMM slots.
Previously I had 4x4GB modules. I could only get 12GB to show up though. The BIOS would see all four, Memtest86 would see all four, but would report only three usable.
The odd part was it would happen no matter what configuration the memory was in. I have a SuperMicro H8DCL line board, which has 8 memory slots. It does not matter if I use Channel A, Channel B, just the slots on CPU1, or just the ones on CPU2. The results are always the same.
I figured it must be an issue with that memory kit, so I upgraded to 4x Hyinx 8GB ECC modules. Memtest can see all four, but only three are usable.
Has anyone seen this before? Anyone know what is going on? I cant for the life of me figure it out.
Thanks!
