64GB DDR4 3200 ECC RDIMM for Supermicro servers

This 64GB registered DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It is built for Supermicro servers and workstations that require ECC registered memory for data integrity. The single 2Rx4 DIMM adds high-density capacity in one slot.

288-pin registered DIMM with major-brand DRAM

The module uses Samsung, Micron or Hynix chips on a standard 288-pin RDIMM PCB without a heat spreader. Registered buffering reduces electrical load on the memory controller, allowing stable operation in multi-DIMM server configurations. The low-profile design fits dense chassis.

Verify DDR4 RDIMM support and slot population rules

Confirm the motherboard accepts DDR4 3200 ECC RDIMM modules and check the qualified vendor list for 64GB 2Rx4 parts. Some platforms limit maximum capacity per channel or require specific slot-filling order. Ensure the system BIOS is current before installation.

Questions about this item

What speed does the DDR4 3200 interface cap at in practice?

The module runs at 3200 MT/s (PC4-25600) with CL22 latency and 1.2 V operation.

What physical slot and form factor does this 64 GB module need?

It requires a 288-pin DDR4 RDIMM slot and uses a 2Rx4 registered layout without a heat spreader.

How is the ECC RDIMM installed, and what step do people often miss?

Insert the module firmly until the retention clips lock; the common mistake is not seating both ends evenly, leaving one side partially engaged.
