Server Memory Upgrade

This 32GB DDR5 module operates at 4800MHz with CL40 latency and 1.1V voltage. It is built as a 2Rx8 registered ECC RDIMM using Samsung-compatible components for server and workstation platforms.

Registered ECC Compatibility

The 288-pin RDIMM format requires a motherboard that supports registered ECC memory and DDR5 architecture. It fits into a single DIMM slot, leaving additional channels open for further capacity expansion.

Sustained Workload Stability

Each module undergoes stress testing under load to maintain reliability during continuous operation. The registered buffer and ECC functionality preserve data integrity across extended compute tasks in enterprise environments.

Questions about this item

What limits the 32GB DDR5 4800 module when it runs under sustained load?

The registered buffer and CL40 latency govern command timing, while the fixed 1.10V supply caps power draw during continuous operation.

How much heat and noise does the 288-pin ECC RDIMM produce in a server running all day?

The module has no heat spreader and no moving parts, so it adds only its own thermal load to the chassis airflow and makes no audible noise.

What must the system already provide for this 2Rx8 registered DIMM to function?

A DDR5 RDIMM slot with ECC support and a memory controller that accepts registered modules at 1.10V.
