8GB DDR4 2666 ECC RDIMM for HP Servers
This 8GB DDR4 2666 ECC RDIMM module is built for HP server and workstation systems that require registered memory with error correction. It replaces part numbers 864706-591 and L09284-850 in compatible platforms. The single-rank 1Rx8 design operates at 1.20V with CL19 latency. Buyers who need non-ECC memory or unbuffered DIMMs for desktop boards cannot use this module.
Registered ECC design with major brand chipset
The registered buffer reduces electrical load on the memory controller, allowing stable operation in multi-module server configurations. ECC circuitry detects and corrects single-bit errors to protect data integrity in critical workloads. Major brand chipset components are used throughout. No additional software or drivers are included; the module functions purely as a hardware upgrade.
288-pin DIMM installs in standard DDR4 slots
Installation follows the usual DIMM procedure: align the notch with the key in the 288-pin slot and press until the retention clips engage. The 1.20V operating voltage matches the DDR4 standard, so no manual voltage adjustment is required. The most common issue is purchasing this registered ECC module for a system that only accepts unbuffered non-ECC memory, which will prevent the system from posting.
