INTRODUCTION
It is important to be aware of the system considerations listed below before installing your
SSP8268 (8268-xxx) motherboard. Overall system performance may be affected by incorrect
usage of these features.
DDR4-2933 MEMORY
Trenton Systems recommends unbuffered ECC DDR4-2933 PC4-23400 memory modules for use
on the SSP8268. The SSP8268 supports a maximum of 1.5TB of memory across 12 ECC RDIMM
slots using six channels per CPU.
NOTES:
To maximize memory interface speed, populate each memory channel with DDR4 DIMMs
having the same interface speed. The motherboard will support DIMMs with different speeds,
but the memory channel interface will operate speed of the slowest DIMM.
All memory modules must have gold contacts.
All memory modules must have a 288-pin edge connector
Populate the memory sockets starting with memory channel A and begin by using the DIMM
socket closest to the CPU first. Refer to the SSP8268 board layout drawing and populate the
memory sockets using the population order illustrated in the chart below:
