Kingston 32 GB DDR5 4800 ECC DIMM

This 32 GB DDR5 module runs at 4800 MT/s with CL40 latency and operates at 1.10 V. It is built for workstation and server platforms that require ECC protection and unbuffered signalling. The dual-rank 2Rx8 organisation fits a standard 288-pin DIMM slot.

ECC and unbuffered operation

On-die ECC corrects single-bit errors to maintain data integrity in critical workloads. Unbuffered signalling reduces command overhead compared with registered alternatives, which can lower latency for supported platforms. These traits suit environments where uptime and accuracy matter more than maximum capacity per channel.

DDR5 4800 interface limits

The DDR5 4800 standard caps transfer rate at 4800 MT/s and defines PC5-38400 bandwidth. CL40 timing is fixed for this speed grade, so tighter latencies are not available without moving to a higher data rate. Systems that only support lower DDR5 speeds will downclock the module, reducing throughput. Buyers needing higher bandwidth or registered DIMMs must select a different specification.

Questions about this item

Will the ECC unbuffered design require any firmware updates or module replacements over time?

The module runs at 1.10 V with CL40 latency and 2Rx8 organisation; no firmware updates are needed and the memory itself has no replaceable parts.

What thermal or power ceiling appears first when the DIMM runs continuously at 4800 MHz?

Sustained operation stays within the standard 1.10 V DDR5 specification; the first limit is the platform's own cooling capacity for the 32 GB dual-rank module.

How much fan noise or case heat does a 32 GB DDR5 4800 CL40 stick add during all-day workloads?

The 1.10 V unbuffered DIMM draws minimal power, so it contributes negligible extra heat or fan noise in a properly ventilated chassis.
