64GB DDR4 2666 ECC kit

This 64GB kit contains four 16GB unbuffered UDIMMs rated at DDR4 2666 PC4-21300 with ECC. It targets servers and workstations that require error-correcting memory in the standard 288-pin form factor.

Practical limits of DDR4 2666 ECC UDIMM

The modules run at 1.2V with a CAS latency of 19 and a 2Rx8 organisation. Unbuffered ECC DIMMs of this speed are limited to platforms whose memory controllers support both ECC and unbuffered operation at 2666 MT/s.

Major OEM chips and 288-pin layout

Chips are sourced from Samsung, Micron or Hynix depending on supply. The standard 288-pin edge connector fits any DDR4 UDIMM slot, and the unbuffered design means no register delay, which suits single-socket boards that do not accept registered modules.

Questions sur cet article

Should I pick the 4 x 16 GB kit or a different capacity?

This kit provides 64 GB total across four 16 GB modules, giving you full capacity in four slots while keeping each module at the standard 1.2 V DDR4 voltage.

What does the 2666 MHz rating mean once the memory is installed?

The modules run at DDR4 2666 with CAS latency 19, delivering PC4-21300 bandwidth when the platform supports that speed and the memory controller is configured for it.

How does the ECC UDIMM interface affect what I can use it with?

These are 288-pin unbuffered ECC DIMMs (2Rx8), so they fit standard DDR4 UDIMM slots that accept ECC; they will not work in registered-only or non-ECC-only platforms.
