8GB DDR4 ECC UDIMM for Servers

This 8GB DDR4 2666MHz ECC unbuffered DIMM is built for server and workstation systems that require error-correcting memory. It operates at 1.2V with a CL19 latency and a single-rank 1Rx8 organisation. The module uses major-brand chips and is tested for dependable operation in compatible platforms.

DDR4 2666 speed and 288-pin limit

The DDR4 2666 (PC4-21300) interface sets the maximum data rate and the 288-pin DIMM form factor determines physical fit. Systems that only support lower DDR4 speeds will down-clock the module, while boards limited to registered DIMMs cannot accept this unbuffered design. The 1.2V standard voltage is fixed for DDR4 and cannot be adjusted on this part.

ECC unbuffered decides compatibility

The single specification that determines whether this module works is the ECC unbuffered (UDIMM) designation. Servers or workstations that require registered (RDIMM) or load-reduced (LRDIMM) memory will not accept it, and consumer boards without ECC support cannot use the error-correction feature. Verify the motherboard manual calls for DDR4 ECC UDIMM before purchase.

Questions about this item

Should I choose the 8GB module or a different capacity for my server?

This listing is a single 8GB module; add more identical sticks to reach the total capacity your motherboard supports.

What does the 2666MHz speed mean once installed in my system?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency at 1.20V, delivering that bandwidth if the platform supports it.

Is the 288-pin DDR4 interface compatible with standard server boards?

Yes, it uses the 288-pin DDR4 DIMM form factor and ECC unbuffered signalling used by many server and workstation platforms.
