8GB DDR4 2666 ECC RDIMM for HP servers

This 8GB DDR4 2666 registered ECC module is built for HP server and workstation platforms that require registered memory. It uses major-brand chips and operates at 1.2V with CL19 timing. The 2Rx8 organisation and 288-pin DIMM form factor match the HP part numbers listed.

Suited for administrators expanding memory

Buyers who need unbuffered UDIMM modules, higher frequencies, larger single-module capacities, or non-ECC memory for consumer platforms should look at something else. This part is strictly for registered ECC DDR4 environments.

Registered ECC with 2Rx8 organisation

The registered ECC design with 2Rx8 rank structure is the single specification that determines whether this module will work in your HP server. Verify that your system documentation calls for registered ECC DDR4 2666 2Rx8 DIMMs before ordering.

Questions about this item

Does the box contain only the 8GB DDR4 2666 ECC RDIMM module or are any cables or brackets included?

The package includes one 8GB DDR4 2666MHz PC4-21300 ECC RDIMM module; no cables, brackets or additional accessories are supplied.

Should I choose this single 8GB 2Rx8 module or look for a different capacity for my HP server?

This is a single 8GB 2Rx8 module; select it if your system requires an 8GB registered DIMM, otherwise choose a different capacity that matches your server's supported configuration.

What does the 2666 MHz PC4-21300 rating mean for actual performance in my HP server?

The module runs at DDR4 2666MHz with CL19 latency and 1.2V voltage, delivering the standard data rate for compatible HP server platforms that support PC4-21300 memory.
