8GB DDR4 2400MHz ECC SODIMM

This 8GB DDR4 2400MHz ECC SODIMM module provides 8GB of DDR4 memory at 2400MHz with CL17 latency and 1.20V operation. It is designed as a compatible replacement for Micron MTA18ASF1G72HZ-2G3B1 in microserver, server, and workstation systems requiring ECC unbuffered SO-DIMM memory.

Sustained load stability with ECC

ECC functionality detects and corrects single-bit errors during continuous operation, helping maintain data integrity in server and workstation workloads. Unbuffered design reduces latency for responsive performance under sustained memory pressure. DDR4 2400 speed delivers consistent throughput for multi-tasking and background services.

Straightforward SODIMM installation

The 260-pin DDR4 SO-DIMM form factor fits standard laptop and microserver slots without adapters. No heat spreader simplifies insertion in tight bays. Verify your system supports DDR4 2400 ECC unbuffered SO-DIMM before purchase to avoid compatibility issues. Modules are tested for reliable operation.

Questions about this item

Does the 1.2V DDR4 2400MHz module run hot or draw extra power when a microserver runs 24/7?

The module operates at standard 1.20V DDR4 voltage with no heat spreader, so it adds minimal heat and power draw during continuous operation.

My motherboard has 260-pin SO-DIMM slots — will this 260-pin ECC SODIMM fit and work without a registered DIMM controller?

Yes, it is a 260-pin unbuffered ECC SO-DIMM (CL17) that fits standard DDR4 SO-DIMM slots; the board must support unbuffered ECC memory.

Can I mix this CL17 ECC stick with my existing Micron MTA18ASF1G72HZ-2G3B1 modules that are also 2Rx8?

It is built as a compatible replacement for that exact Micron part (2Rx8, 2400MHz, ECC unbuffered), so timing and organisation match for mixed use.
