Server-grade DDR5 ECC RDIMM kit

This 64 GB kit comprises two 32 GB DDR5-4800 registered DIMMs built with ECC and a CL40 latency profile. It targets administrators upgrading ASUS RS720Q-E11-IM immersion-cooling servers where registered memory is mandatory.

288-pin registered modules without heat spreaders

Each stick runs at 1.10 V and uses a 1Rx4 organisation based on major OEM DRAM from Samsung, Micron or Hynix. The bare PCB design fits dense 2U4N trays where tall spreaders would block airflow or interfere with immersion manifolds.

Matched pair validated for ASUS RS720Q-E11-IM

The kit ships as a tested 2 x 32 GB set under part number MR38400-314K2, eliminating the guesswork of mixing modules. Rigorous stress testing under load is performed before dispatch so the server can be returned to production immediately after installation.

Questions about this item

What DDR5 standard does the PC5-38400 rating support and what speed does it cap at?

The kit is rated PC5-38400, which corresponds to DDR5 4800 MT/s. The modules will run at up to 4800 MT/s on compatible ASUS server platforms.

What physical slot and form factor do these 288-pin RDIMMs require?

Each 32 GB module is a 288-pin DDR5 RDIMM measuring 1Rx4. They fit standard DDR5 RDIMM slots on the ASUS RS720Q-E11-IM motherboard.

How are the two modules installed and which step is often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the retention clips click, then verify both modules are seated before closing the case.
