32GB DDR4 2666MHz ECC RDIMM

This 32GB DDR4 2666MHz module uses Samsung chips and carries Supermicro certification. It targets administrators expanding memory in compatible Supermicro servers and workstations that require registered ECC DIMMs.

Registered 288-pin form factor

The RDIMM registered design places a buffer on the command and address lines to reduce electrical load on the memory controller. Its 288-pin edge connector fits standard DDR4 RDIMM slots and the 1.20V operating voltage matches the DDR4 baseline.

DDR4 2666MHz bandwidth ceiling

At DDR4 2666 (PC4-21300) the peak transfer rate is fixed by the JEDEC standard for this speed grade. Systems limited to lower memory bus frequencies will clock the module down, reducing available bandwidth accordingly.

Questions about this item

What speed does the DDR4 2666 standard cap this module at in practice?

The module runs at 2666 MHz with a PC4-21300 data rate, so throughput is limited to that specification.

What physical slot and pin count does this RDIMM require?

It fits a standard 288-pin DDR4 RDIMM slot on a server motherboard.

How do you install this ECC registered DIMM and what step is often missed?

Power down, open the chassis, align the notch with the key in the 288-pin slot, press firmly until both retention clips lock, then verify in BIOS that ECC registered mode is enabled.
