8GB DDR4 2666 ECC RDIMM for Servers

This 8GB DDR4 2666MHz ECC Registered DIMM targets administrators expanding memory in compatible servers and workstations. The module uses major-brand chips in a 2Rx8 organisation and runs at the standard 1.20V. It replaces the Micron MTA18ASF1G72PDZ-2G6 part number directly.

Upgrade from non-ECC or lower-capacity modules

The jump is worthwhile when workloads demand error-correcting code protection and registered signalling for platform stability. Systems limited to unbuffered memory or single-rank configurations cannot use this module. Verify the motherboard qualified-vendor list before ordering.

DDR4 288-pin registered interface constraints

The 288-pin DDR4 RDIMM form factor fits only slots wired for registered operation and DDR4 electricals. Mixing with unbuffered DIMMs or different-speed modules may prevent boot or force reduced frequency. Population rules vary by platform; consult the system manual for supported rank counts per channel.

Questions about this item

Does this 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the module uses the 288-pin DDR4 DIMM form factor and registered ECC design required by compatible server and workstation motherboards.

What is the correct way to seat the module so the ECC registration initialises?

Align the notch with the slot key, press firmly until both retention clips click, then power on so the register and ECC logic train at 1.2 V.

When should the 2Rx8 8 GB stick be replaced to keep ECC protection reliable?

Replace it if the system logs uncorrectable ECC errors, fails memory diagnostics, or no longer posts after verified seating and firmware updates.
