R830 memory config

Question

I have the following in an R830. All sticks are 2400 MT/s, and the system works, but I am wondering whether this is a good configuration. Currently the set up is:

8x 32GB sticks populating A1 to A4 & B1 to B4

8x 8GB sticks populating C1 to C4 & D1 to D4.

Reading this I get the impression with this setup CPUs 3&4 will only have access to 32GB each. Is that correct, & if so would it be better to move 4x of the 32GB sticks to C1, C2, D1 & D2, and 4x of the 8GB sticks to A3, A4, B3, B4 (so that all CPUs will have access to 80GB RAM each).

Hello,

I'll give you this, please see if you can follow the table below.

A B C D- they all have to be the same number, please note.

2ea X 32GB + 2ea X 8 GB

@DELL-Young E​ Thank you. While the other configuration worked, making them symmetrical as you suggested made a 20% improvement in my (Passmark) memory benchmarks.
