Server-grade ECC RDIMM

This single 128GB DDR4 2933 module uses a registered ECC design built for ASRock bare-bone servers such as the RM23724-C622LM/22E. It targets administrators who need maximum capacity per slot in workstation or NAS platforms that require registered memory.

288-pin registered layout

The 8Rx4 organisation and 1.2V operation follow JEDEC and RoHS standards without a heat spreader, so the module fits dense 4U or 2U chassis where airflow is managed by the system. Registered signalling adds one clock cycle of latency but allows the memory controller to drive many ranks reliably.

DDR4 2933 ceiling

Speed steps down automatically to 2666, 2400 or 2133 MHz when the platform demands it, but cannot exceed the rated 2933 MT/s. Mixing with unbuffered or load-reduced DIMMs is not supported, so every slot must use the same registered ECC type.

Soalan tentang produk ini

What DDR4 speed and CAS latency does this 128GB ECC RDIMM run at?

It operates at DDR4 2933 (PC4-23400) with a CAS latency of 21.

Does this 288-pin module need a heat spreader or special clearance to fit in an ASRock RM23724-C622LM/22E?

No heat spreader is present; the standard 288-pin RDIMM height fits the server's DIMM slots without extra clearance.

How do I install this registered ECC module and what common step should I avoid?

Power down, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both latches click. Do not mix with unbuffered or load-reduced DIMMs.
