Server-grade 128GB ECC RDIMM
This single 128GB DDR4 3200 module delivers registered ECC memory for ASRock server motherboards including the SP2C621D16-2L+, SP2C621D16-2T, SP2C621D16-2T/X550, SP2C621D16HM3 and SP2C621D16N-2L2T. It targets administrators who need maximum capacity per slot in workstation or NAS environments. Builders using standard desktop platforms cannot use this memory.
JEDEC-standard registered design
The module follows JEDEC and RoHS specifications at 1.2V with CL22 latency and 8Rx4 organisation. Backward compatibility lets it run at 2133, 2400, 2666 or 2933 MHz when the platform requires lower speeds. It must not be mixed with unbuffered or load-reduced DIMMs.
288-pin form factor without heat spreader
The bare 288-pin RDIMM fits dense server chassis where tall spreaders would block airflow or adjacent slots. Registered signalling reduces electrical load on the memory controller, supporting stable operation in multi-DIMM configurations. Buyers needing unbuffered ECC or consumer DDR4 should look elsewhere.

Spørgsmål om denne vare
Will the 8Rx4 rank configuration require replacement if I expand beyond this single 128GB module?
The 8Rx4 organisation uses all ranks on one 288-pin DIMM; adding further modules depends on the motherboard's maximum rank-per-channel limit, not on this stick itself.
What thermal limit appears first when the registered ECC DIMM runs at 3200 MT/s continuously?
Without a heat spreader the DRAM junction temperature will reach its JEDEC maximum before the 1.2 V supply or the register becomes the bottleneck.
How much extra power and noise does the registered buffer add during 24/7 server operation?
The on-DIMM register draws only milliwatts more than an unbuffered module and produces no audible noise; total power stays at the standard 1.2 V DDR4 level.
