M321RAJA0MB0-CWM
M321RAJA0MB0-CWM is an enterprise-grade DDR5 Registered ECC memory module from Samsung. The RDIMM register chip optimizes clock and command signals, improves signal integrity, and supports more stable multi-DIMM expansion on enterprise server motherboards. ECC function automatically detects and corrects memory bit errors, reducing the risk of unexpected downtime in 24/7 operating environments.
It supports high-speed 5600MT/s data transmission and PC5-44800 bandwidth performance. The 1.1V low-voltage design helps reduce power consumption and heat generation compared with previous generation server memory. Each module is fully tested before shipment to ensure reliable operation under continuous load. It is compatible with mainstream enterprise server platforms and widely used in cloud hosts, data centers, AI inference and enterprise business systems.

Q1: Is M321R4GA0PB0-CWMKJ RDIMM usable on normal desktop motherboard?
A: No. RDIMM Registered memory only works on server motherboards that support RDIMM. Ordinary consumer desktop motherboards cannot identify it.
Q2: What is RDIMM? What is difference between RDIMM and UDIMM?
A: RDIMM has register chip, better signal stability when install many memory modules on server board. UDIMM has no register, usually used for workstation.
Q3: Is this memory tested before shipment?
A: Yes, every module passes full functional test to ensure no bad chips.
Q4: Can I mix RDIMM with UDIMM on one server motherboard?
A: Not recommended. Mixing RDIMM and UDIMM may cause boot failure or system instability.
Q5: What is the warranty period?
A: 1 year warranty, replace defective items.
