SuperMicro Compatible 64GB Kit

This 64GB kit contains eight 8GB DDR4 UDIMM modules validated for SuperMicro motherboards such as the MBD-C9X299-PGF. It targets administrators and builders who need reliable, non-ECC memory for workstation or desktop workloads on that platform.

Upgrade From Lower Capacity Or Speed

Replacing smaller DDR4 kits or slower DDR4 modules with this 2933 MT/s CL21 set adds bandwidth and capacity in a single step. The jump is worth it when the board supports DDR4 2933 and the workload benefits from eight populated slots.

Eight Modules At 1.2V

Eight ranks of 1Rx8 chips run at 1.20V, giving 64GB of headroom for multi-threaded applications and virtual machines. The kit runs out when the board's maximum memory limit or channel population rules prevent all eight modules from operating at the rated speed.

Questions about this item

How many 288-pin DDR4 UDIMM slots does my Supermicro motherboard need free to install all eight modules in this 64GB kit?

You need eight free 288-pin DDR4 UDIMM slots to install the full 64GB kit of eight 8GB modules.

What is the correct orientation step when seating these 1Rx8 unbuffered modules so the notch aligns with the 288-pin key?

Align the module notch with the slot key, press straight down evenly on both ends until the retention clips click, and verify the module sits flat with no visible gold contacts.

If a Samsung, Micron or Hynix DRAM chip fails years from now, is the module covered for replacement?

Yes, the kit carries a lifetime replacement warranty from the manufacturer, so a defective module can be replaced for the life of the product.
