Server DDR4 ECC UDIMM 8GB

This 8GB DDR4 2400MHz ECC unbuffered module targets server and workstation operators who need error-correcting memory for data integrity. It replaces Micron MTA9ASF1G72AZ-2G3A1 and MTA9ASF1G72AZ-2G3B1 parts in compatible platforms. The 1Rx8 organisation and 1.20V operation suit standard DDR4 DIMM slots. Builders requiring registered or load-reduced DIMMs cannot use this module.

Verified compatibility replacement

The module is tested as a direct equivalent for the two Micron part numbers listed, so it fits the same 288-pin DIMM sockets without firmware changes. ECC functionality activates automatically on platforms that support unbuffered error correction. No additional software, heat spreaders or configuration utilities are bundled with the memory stick.

8GB capacity at DDR4 2400 CL17

The single 8GB rank delivers 19200 MB/s peak bandwidth at CL17 latency, handling typical virtualisation hosts, file servers and database workloads that fit within 8GB per slot. Workloads needing larger per-slot densities or higher frequencies will exceed this module's headroom. Systems limited to lower DDR4 speeds will downclock automatically.

Questions about this item

Will the ECC UDIMM need replacement after a certain number of write cycles?

ECC UDIMM memory does not have a write-cycle limit like flash storage; it is replaced only if a module fails or capacity needs increase.

What limits sustained throughput on this DDR4 2400 CL17 module?

The DDR4 2400 PC4-19200 rating and CL17 latency set the maximum sustained bandwidth and access speed.

How much heat does the 1.20 V 8 GB stick produce under all-day load?

At 1.20 V the module runs at standard DDR4 voltage, generating typical low heat for an unbuffered ECC DIMM.
