Server Memory Upgrade

This A-Tech module delivers 16GB of DDR4 ECC registered memory at 2933MHz with CL21 latency. It uses a 2Rx8 organisation and operates at the standard 1.20V. The 288-pin RDIMM form factor fits server and workstation platforms that require registered error-correcting modules. It serves administrators who need to expand capacity in compatible systems.

Replaces Hynix Modules

The module is a direct equivalent for Hynix part numbers HMA82GR7CJR8N-WM, HMA82GR7DJR8N-WM and HMA82GR7JJR8N-WM. The upgrade is worthwhile when a system supports DDR4 2933 registered ECC memory and has free DIMM slots for capacity expansion. It is not for systems that require unbuffered UDIMMs, load-reduced LRDIMMs or a different DDR generation.

DDR4 Interface Limits

DDR4 2933 registered ECC memory requires a platform memory controller that supports this speed and the registered command-address protocol. The 2Rx8 density may impose population limits on some motherboards. Buyers who need higher frequencies, greater densities per module or non-ECC operation must select a different memory standard.

Questions about this item

Will the 288-pin DDR4 DIMM fit my server's RDIMM slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor and is built as an ECC RDIMM, so it fits any server or workstation slot that accepts registered DDR4 memory.

Do I need to install this 2Rx8 registered module in a specific slot order?

Install the module in the slot sequence recommended by your system manual; the common mistake is mixing registered and unbuffered DIMMs or placing a 2Rx8 module in a channel that requires single-rank population.

How can I tell when the 16GB ECC RDIMM should be replaced?

Run the platform's built-in memory diagnostics or ECC error counters; a rising count of corrected errors or any uncorrectable error indicates the module should be swapped out.
