HP L36843-001 Compatible Server Memory

This 16 GB DDR4 module replaces HP part L36843-001 in servers and workstations. It delivers ECC unbuffered operation at 2666 MHz with a CL19 latency. The single DIMM suits administrators upgrading compatible HP platforms.

DDR4 2666 Unbuffered ECC Limits

Unbuffered ECC DIMMs rely on the memory controller for error correction without a register buffer. This caps usable capacity per channel and maximum supported frequency on many server boards. The 1.2 V standard voltage is fixed for DDR4 and cannot be lowered.

Dual-Rank 2Rx8 Organisation

The 2Rx8 rank layout places sixteen memory chips across two ranks on the module. This organisation determines electrical loading on the memory bus and must match the platform’s qualified vendor list. Verify the server’s supported rank configuration before purchase.

Questions about this item

Should I pick the 16GB 2Rx8 module or a different capacity for my HP L36843-001 slot?

This is a single 16GB DDR4 2666 ECC UDIMM built to match the HP L36843-001 part number; choose it when your server needs one 16GB stick with 2Rx8 organisation.

What does the DDR4 2666 CL19 rating deliver inside a server?

The stick operates at 2666 MT/s with CAS 19 at 1.20V, providing ECC error correction and unbuffered signalling for compatible HP platforms.

Does the 288-pin DDR4 interface limit the speed to 2666 on my board?

The module is a 288-pin DDR4 DIMM rated for 2666 (PC4-21300); the memory controller of your system determines the final operating speed.
