64GB DDR5 ECC kit for server builds

This 64GB kit contains four 16GB DDR5 4800MHz ECC UDIMM modules. It targets administrators upgrading or repairing servers that require unbuffered error-correcting memory. Buyers needing registered DIMMs or non-ECC desktop memory should look elsewhere.

Unbuffered ECC UDIMM at 4800MHz

The modules run at DDR5 4800 (PC5-38400) with a CAS latency of 40 and operate at 1.1V. Each stick is a 1Rx8 288-pin unbuffered DIMM, so the motherboard must support unbuffered ECC DDR5 at this exact speed and pin count.

Straightforward DIMM installation

Align the notch on each 288-pin module with the slot key and press firmly until the retention clips click. Common issues include mixing these unbuffered sticks with registered DIMMs, populating slots in the wrong order for the platform, or forgetting to enable ECC in the BIOS.

Questions about this item

What does the 4800MHz rating mean once the kit is installed in a server?

The modules run at DDR5 4800 (PC5-38400) with a CAS latency of 40, delivering the rated bandwidth when the platform selects that speed.

How does the ECC UDIMM interface affect what the memory controller can do?

The unbuffered ECC design connects directly to the memory controller, providing error correction without the added latency of registered modules.

What physical slot and pin count does this 288-pin kit require?

Each 16GB module uses the standard DDR5 288-pin UDIMM form factor and fits a compatible DDR5 UDIMM socket.
