128 GB ECC Registered DDR4 for ASRock EP2C621D12 WS
This single 128 GB DDR4 2933 module uses an 8Rx4 registered design with ECC and operates at 1.2 V. It is built for the ASRock EP2C621D12 WS workstation motherboard and the listed compatible server boards.
Sustained CL21 2933 operation
Registered buffering and ECC keep data integrity stable during long compute runs on workstations and servers. The module also runs at 2133, 2400 or 2666 speeds when the platform requires a lower frequency.
288-pin RDIMM without heat spreader
The bare 288-pin form factor fits dense DIMM arrays where tall spreaders would block airflow. It cannot be mixed with unbuffered or load-reduced modules and is not compatible with standard desktop systems.

Pytania dotyczące tego produktu
How much heat or power does the 128GB DDR4 2933 registered module draw when running continuously?
It operates at 1.2V without a heat spreader, so power draw and heat output stay low during all-day workloads.
What motherboard must I already own for this 288-pin ECC RDIMM to work?
It is validated for the ASRock EP2C621D12 WS and also listed for EP2C622D24LM2, EPC621D4I-2M, EPC621D6U-2T16R and WC621D8A-2T.
Will this 8Rx4 CL21 module run alongside slower DDR4 DIMMs I already have installed?
Yes, the spec notes backward compatibility with 2133MHz, 2400MHz and 2666MHz DDR4, so it will down-clock to match existing sticks.
