32GB DDR5 4800 ECC Registered RDIMM
This 32GB DDR5 4800 CL40 module is a registered ECC RDIMM built for servers and workstations. It runs at PC5-38400 speed with 1.1V voltage and a 1Rx4 rank layout. The 288-pin design matches the Samsung M321R4GA0BB0-CQK part number for direct replacement.
Verify registered ECC support and voltage
Your motherboard must accept DDR5 registered ECC RDIMMs; standard desktop boards cannot use this memory. Confirm the system requires 1.1V operation and CL40 timing at 4800 MT/s. Do not mix this module with unbuffered or load-reduced DIMMs, as the registered buffer changes electrical signalling.
Suits server upgrades and Samsung replacements
Ideal for administrators extending the life of compatible Samsung-equipped servers or building new JEDEC-compliant nodes. Not for desktop PCs, laptops, or consumer motherboards that lack registered ECC support. Buyers who need unbuffered ECC or non-ECC memory should look at other modules.

שאלות על הפריט הזה
Does the 288-pin DDR5 ECC Registered RDIMM arrive as a single 32GB module or do I need to purchase additional sticks?
The module is a single 32GB stick; order one per slot you plan to populate.
Should I choose the CL40 4800 version or a different latency for my Samsung M321R4GA0BB0-CQK replacement?
Match the original CL40 4800 spec; mixing latencies can prevent the server from posting.
What does the 4800 PC5-38400 rating deliver once the RDIMM is installed in a compatible server?
It runs at 4800 MT/s with ECC error correction and registered buffering for stable multi-rank operation.
