T7920 Memory Upgrade
I am currently running 128GB 2933MHz memory (8x16GB) and decided since I have 4 more slots free, I purchased anther 4x16GB, identical to what is already installed.
Now on start up the system will not post, they are all configurated in the correct DIMM slots.
The only difference between current and new is different manufacture dates.
Is there something I need to change in the BIOS, running latest BIOS by the way.
CPU0 DIMM 2,4,6,5,3,1
CPU1 DIMM 1,3,5,6,4,2
Help!!

(Take note of current BIOS settings before reset)

Should I stay with the 2Rx8?

Everything is posted above Steve
But here is a picture of the new memory and all looks identical!! Only thing that stands out to me is the different manufacturing dates.

What I would try is.
1. Use your old memory at
CPU0 DIMM 2,4,3,1. Put New memory at CPU0 DIMM 5, 6
CPU1 DIMM 1,3,4,2. Put New memory at CPU1 DIMM 5, 6. See if that will work.
If that still doesn't work. somehow the memory can't work as 6 stick per cpu combo. then I'll
2. still put Old memory at
CPU0 DIMM 2,4,3,1.
CPU1 DIMM 1,3,4,2.
but new memory at CPU0 7, 8. CPU1 7, 8 using different memory channel.
If that doesn't work then I'll test new 4pc alone to see if anything is faulty or you'll just have to get 6pc set for it.

Did you check if the memory voltage or timings need to be manually adjusted in the BIOS? I’ve heard that sometimes mixing memory from different manufacturing dates can cause instability, even if the specs are the same. Also, did you try lowering the frequency, like down to 2666MHz, to see if that helps?
