Server ECC upgrade

This 128GB DDR4 2933 CL21 8Rx4 ECC Registered RDIMM is built for ASUS Rack Server RS500-E9 and RS700-E9 series systems. It targets administrators who need maximum capacity in a single 288-pin module to extend the life of existing infrastructure.

Registered DDR4 constraints

The module runs at 1.2V with JEDEC PC4-23400 timing and will down-clock to 2133, 2400 or 2666 MHz when the platform requires it. It cannot be mixed with unbuffered or load-reduced DIMMs and will not function in standard desktop or consumer workstation boards.

Single-module density

A single 128GB stick leaves remaining slots free for future expansion while delivering 8Rx4 organisation for high-density server workloads. The bare 288-pin PCB has no heat spreader, so airflow across the DIMM row must be maintained by the chassis design.

Kysymyksiä tästä tuotteesta

Should I pick this single 128GB 8Rx4 module or combine smaller DIMMs to reach the same capacity?

This is one 128GB DDR4 2933 CL21 8Rx4 ECC Registered RDIMM; using a single module fills one slot and leaves remaining slots free for future expansion.

What does the 2933 MT/s rating deliver in an ASUS RS500-E9 or RS700-E9 server?

The module runs at DDR4 2933 (PC4-23400) with CAS 21 at 1.2V; the server’s memory controller will operate it at that speed or at a supported lower speed such as 2666, 2400 or 2133 MT/s.

How does the DDR4 288-pin ECC Registered interface limit usable bandwidth?

The 288-pin DDR4 ECC Registered interface connects at up to 2933 MT/s; registered buffering adds one cycle of latency but allows the platform to populate all slots without signal-integrity limits.
