Server ECC UDIMM upgrade
This 16GB DDR4 2666MHz module is built for servers and workstations that require error-correcting unbuffered memory. It delivers 1.20V standard voltage and CL19 latency for stable operation in compatible HP platforms. The single 288-pin DIMM uses a 2Rx8 organisation with major-brand chips.
ECC unbuffered requirement
The deciding specification is ECC UDIMM; systems that accept only registered or non-ECC DIMMs will not support this module. Verify that your motherboard and BIOS explicitly list ECC unbuffered DDR4 2666 support before ordering.
HP part-number match
The module replaces HP part numbers 3TQ40AA, 3TQ40AT and 879527-091, so it fits the qualified memory lists for those configurations. No extra cables, brackets or software are included in the package.

Kysymyksiä tästä tuotteesta
What does the 2666MHz speed mean once the module is installed?
The module runs at 2666MHz DDR4, delivering PC4-21300 bandwidth; the system memory controller sets the final data rate.
How does the ECC UDIMM interface affect what the memory can do?
ECC UDIMM provides single-bit error correction on an unbuffered 288-pin DDR4 bus, so data integrity is checked without registered delay.
What physical slot and clearance does this 288-pin DIMM need?
It fits a standard 288-pin DDR4 DIMM socket and uses 1.2V; verify your board accepts unbuffered ECC modules before installing.
