32GB DDR4 ECC RDIMM kit

This 32GB kit contains four 8GB DDR4 2133 MHz registered DIMMs built for servers and workstations. Each module uses a 1Rx4 single-rank layout and operates at 1.2V with CL15 latency. The kit is not compatible with desktop or laptop computers.

Registered ECC requirement

Your system must support DDR4 registered ECC RDIMM memory; the modules will not work in platforms that accept only unbuffered non-ECC DIMMs. Verify the motherboard or server manual for qualified memory configurations before purchasing.

Straightforward DIMM installation

Align the 288-pin modules with the DDR4 DIMM slots and press firmly until the retention clips lock. Follow the manufacturer's channel population rules for quad-channel operation. A common issue is mixing registered and unbuffered DIMMs, which prevents the system from posting.

Questions about this item

Will the 2133 MHz rating hold once the kit is installed in a server?

The modules run at DDR4 2133 MHz (PC4-17000) when the platform supports that speed; actual operating frequency follows the system's memory controller and populated channel configuration.

What does the registered ECC RDIMM interface mean for bandwidth limits?

Registered ECC RDIMM adds a register between the DRAM and the memory bus, allowing higher module counts per channel while ECC corrects single-bit errors; peak bandwidth is capped by the DDR4 2133 data rate.

How many 288-pin DIMM slots does this quad-channel kit occupy?

The kit contains four 8 GB modules, each a 288-pin DDR4 DIMM, so it fills four slots — one per channel in a quad-channel server or workstation board.
