HP J9P83AA 16GB DDR4-2133 ECC Registered server RAM

SKU CH-3HJ9-T1AFQ MPN J9P83AA

16 GB DDR4-2133 ECC registered memory module for Z440, Z640 and Z840 workstations

  • 16 GB capacity expands workstation memory headroom
  • DDR4-2133 speed delivers 17000 MB/s peak bandwidth
  • ECC registered design protects data integrity in critical tasks
  • Single 16 GB module simplifies upgrade planning
  • Compatible with HP Z440, Z640 and Z840 workstations

Capacity and purpose

This HP J9P83AA module provides 16 GB of DDR4-2133 ECC registered memory for compatible workstations. It is a single 16 GB stick rated at PC4-17000 with a 2133 MHz clock speed. The registered design adds a buffer that helps maintain signal integrity in multi-module configurations. It targets professionals who need error-correcting capacity for data-sensitive workloads.

Fit and alternatives

The module suits owners of HP Z440, Z640 or Z840 workstations that require registered ECC DDR4 memory. Builders using consumer desktop boards or laptops that only accept unbuffered non-ECC modules should look elsewhere. Systems limited to lower-density DIMMs or a different memory standard will not be compatible with this stick.

Build integration

Installing this DIMM adds 16 GB of protected memory to a supported workstation without occupying additional slots beyond the single module. The registered signalling reduces electrical load on the memory controller, which helps when populating multiple channels. Physical dimensions are 5.3 inches in length and 1.2 inches in width with a 28.7 mil thickness.

商品問答

Does my HP workstation need a Z440, Z640 or Z840 motherboard to use this J9P83AA module?

Yes, the module is validated for HP Z440, Z640 and Z840 desktop workstations and requires a system that accepts DDR4-2133 ECC registered memory.

Can I keep my existing DDR4-2133 ECC registered DIMMs installed while adding this 16 GB stick?

Yes, you can add this 1x16 GB module alongside other DDR4-2133 ECC registered DIMMs provided the workstation has free slots and the total capacity stays within the platform limit.

How do I confirm the system sees the full 16 GB at 2133 MHz after installation?

Check the BIOS memory information or the OS task manager; both should report 16 GB detected and a speed of 2133 MHz for the new module.
