8GB DDR3L ECC RDIMM for Servers

This 8GB registered DIMM runs at DDR3L 1600 with CL11 latency and a 1.35V low-voltage profile. It uses major-brand chips in a 1Rx4 organisation to deliver error-correcting memory for server and workstation platforms that require registered modules.

Verify registered ECC support and DDR3L voltage

Confirm that your motherboard accepts registered ECC DIMMs and operates at 1.35V before ordering. Standard unbuffered or non-ECC boards will not post with this module, and 1.5V-only slots may not support the lower voltage.

Single 240-pin module frees remaining slots

The 1Rx4 layout places the full 8GB on one 240-pin stick, leaving additional DIMM sockets open for future capacity expansion. It slots directly into compatible HP part-numbered systems without adapters or configuration changes.
