HMA82GR7CJR4N-WM
HMA82GR7CJR4N-WM is SK Hynix original registered server memory designed for mission-critical enterprise computing workloads. This 288-pin DDR4 RDIMM module delivers 16GB memory capacity with 2933MT/s transfer speed, PC4-23400 specification and CL21 latency.
It comes with ECC (Error-Correcting Code) function, automatically detecting and correcting single-bit memory errors, preventing unexpected server downtime and data corruption for long-running systems. The RDIMM register chip buffers address and command signals, enabling multi-socket servers to support larger total memory capacity than ordinary UDIMM.
With 1Rx4 single-rank architecture and 1.2V low power consumption, it reduces heat generation and power expenditure inside dense server racks. Every memory module undergoes strict aging and compatibility testing before shipment. It has wide compatibility with mainstream brand rack servers and workstations supporting DDR4 ECC RDIMM, ideal for heavy enterprise computing tasks.

Q1: Can HMA82GR7CJR4N-WM work on regular desktop motherboard?
A: No. This is ECC RDIMM server RAM. It only works on server motherboards & CPUs that support ECC RDIMM. Ordinary consumer desktop boards cannot recognize or boot with RDIMM memory.
Q2: What is RDIMM?
A: RDIMM (Registered DIMM) has register chip to buffer control signals. It enables multi-socket servers to install larger total memory capacity, suitable for enterprise data center.
Q3: Can I mix this memory with other DDR4 modules in my server?
A: We recommend to use identical memory modules for best stability. Mixing different rank / type RAM may work but system will run at the slowest speed, and stability risk increases.
Q4: What is the condition of the memory?
A: Fully tested server memory. Please contact us to confirm stock status: new or tested used.
Q5: What is your warranty policy?
A: 3-year warranty. Defective items can be replaced after inspection.
Q6: Does this RAM come with heat sink?
A: No, it is bare PCB server memory without heat spreader, designed for server chassis with good airflow cooling.
