Capacity and fit

This 64 GB kit contains four 16 GB DDR4 UDIMMs rated at 2666 MT/s (PC4-21300) with CL19 timing at 1.2 V. The modules are 1Rx8 unbuffered non-ECC and carry no heat spreaders. They are built specifically for the SuperMicro MBD-C9Z390-CG workstation motherboard.

Before ordering

Confirm that your motherboard is the exact SuperMicro MBD-C9Z390-CG model; other boards may not support this configuration. Verify the CPU and chipset accept 2666 MT/s DDR4 unbuffered non-ECC UDIMMs at 1.2 V. Ensure four free 288-pin DIMM slots are available and that the BIOS is updated to the version recommended by SuperMicro for 64 GB population.

Build integration

The kit fills all four slots on the target board, delivering the maximum supported density without mixing ranks. Standard 1.2 V operation keeps power draw low and leaves headroom for the CPU and add-in cards. No additional cooling is required for the bare modules, and the unbuffered design imposes no extra load on the memory controller.

Questions sur cet article

What comes in the kit and do I need to buy anything else to install it?

The kit contains four 16 GB DDR4 UDIMM modules for a total of 64 GB. No extra parts are required; the modules plug directly into the motherboard's 288-pin slots.

Why choose the 4 x 16 GB CL19 2666 MHz version over a different capacity or speed?

This 64 GB kit matches the SuperMicro MBD-C9Z390-CG's supported DDR4 2666 specification and fills four slots with 1Rx8 modules at 1.20 V for stable operation.

What does the PC4-21300 rating mean once the memory is running in my workstation?

PC4-21300 indicates a peak transfer rate of 21 300 MB/s at 2666 MHz, which is the maximum bandwidth the board's memory controller can use with these CL19 modules.
