64GB DDR4 ECC Registered Kit

This 64GB kit contains four 16GB DDR4 2400MHz ECC Registered DIMMs built for the Gigabyte Server MZ31-AR0 G221-Z30. Each module runs at 1.2V with CL17 timings and a 2Rx8 rank configuration. The 288-pin form factor ensures correct physical fit in the server's memory slots.

Verify Server Model Before Purchase

Confirm the exact system model is Gigabyte Server MZ31-AR0 G221-Z30, as this kit is validated only for that platform. The board accepts Registered ECC or Load Reduced DIMMs but does not support mixing the two types. Memory will clock down automatically based on the installed processor to maintain stability.

Suits Single-Server Capacity Upgrades

This kit suits administrators expanding a single MZ31-AR0 G221-Z30 server to 64GB using matched modules. Buyers needing larger capacities up to the platform maximum or those deploying mixed RDIMM and LRDIMM configurations should look at other options.

Questions about this item

Does the kit include all four 16 GB DDR4 2400 ECC registered DIMMs or must I buy anything else?

The package contains four 16 GB modules for a total of 64 GB. No extra parts are required for installation.

Why choose this 64 GB (4×16 GB) DDR4 2400 CL17 registered ECC kit over other capacities?

It matches the Gigabyte MZ31-AR0 G221-Z30 qualified configuration and fills four of the sixteen DIMM slots, leaving room for future expansion up to 512 GB.

What does the 2400 MHz rating mean once the memory is installed in the Gigabyte MZ31-AR0 G221-Z30?

The modules run at DDR4 2400 (PC4 19200) with CL17 timing at 1.2 V; the system will clock them down automatically if the installed processor requires a lower speed.
