32GB DDR3 ECC Registered Kit

This 32GB kit contains four 8GB DDR3 1333 ECC registered DIMMs built for the HP Workstation Z820. It targets administrators upgrading compatible workstations or servers that require registered memory with error correction.

240-Pin Installation Notes

Modules install in the Z820's 240-pin DIMM sockets using standard alignment keys. The system has 16 sockets across 8 banks of 2; mixing registered and unbuffered ECC modules is not supported and will prevent boot.

Z820 Compatibility Check

Verify your Z820 part number matches the listed manufacturing codes such as B2C03UT through B2C11UT. The platform maximum is 256GB registered ECC and supported speeds are 1066, 1333 or 1600 MHz depending on the installed processor.

Questions about this item

How can I verify the kit is running at the rated 1333 MHz CL9 after installation?

Enter the system BIOS or use a tool such as CPU-Z and confirm the memory frequency reads 1333 MHz with timings of 9-9-9 at 1.5 V.

What exactly ships in the box and is anything else required to use the memory?

The package contains four 8 GB 240-pin DDR3 ECC registered DIMMs; no extra cables, brackets or software are needed.

Why choose this 32 GB (4×8 GB) registered ECC kit over other capacities for the Z820?

This kit matches the workstation’s 1333 MHz registered ECC requirement and fills four of the sixteen DIMM slots, leaving room to reach the 256 GB RDIMM maximum later.
