Server Memory Module

This A-Tech 16GB DDR3L 1333 ECC RDIMM is a registered server memory module built for HP systems. It delivers 16GB of error-correcting capacity at 1.35V low voltage for compatible workstations and servers.

Fit and Alternatives

This module suits administrators upgrading HP ProLiant or Workstation platforms that require DDR3L 1333 registered ECC DIMMs. It is not for desktop PCs, laptops, or any system that only accepts unbuffered non-ECC memory or a different DDR generation.

Deciding Specification

The registered ECC design with 2Rx4 organisation and 1.35V operation determines whether this part matches your server's qualified memory list. Verify your platform requires DDR3L RDIMM registered modules before purchasing.

Questions about this item

How do I install this 240-pin DDR3L RDIMM and what step is often missed?

Align the notch on the 240-pin module with the slot key, press firmly until both clips lock, then verify the server BIOS recognises the 16 GB capacity at 1333 MHz.

What maintenance or replacement will this ECC registered module need over time?

No scheduled maintenance is required; the module is tested for lifetime reliability, and ECC corrects single-bit errors so replacement is only needed if a hard failure occurs.

What limit appears first when this 1.35 V 2Rx4 kit runs under sustained load?

The DDR3L 1333 MHz CL9 specification caps sustained throughput at PC3L-10600 speeds, so bandwidth is the first ceiling reached during heavy workloads.
