32GB DDR5 4800 ECC UDIMM for Workstations

This 32GB DDR5 4800 CL40 module uses a 288-pin unbuffered DIMM form factor with ECC error correction. It runs at 1.1V and follows JEDEC PC5-38400 specifications. The module targets desktop workstations, servers and NAS systems that require data integrity.

JEDEC DDR5 4800 speed and voltage limits

The DDR5 4800 standard sets a base transfer rate of 4800 MT/s at 1.1V with CL40 latency. JEDEC defines these figures as the baseline for interoperability; modules cannot exceed this speed without platform support for higher data rates. ECC operation adds single-bit correction and multi-bit detection within the same timing budget.

Replaces non-ECC or lower-capacity DDR5 UDIMMs

Swapping standard unbuffered DDR5 for this 32GB ECC version adds error correction without changing voltage or slot layout. The upgrade is worthwhile when workloads involve long compute runs, file-server duties or virtualization where silent data corruption is unacceptable. Systems must support unbuffered ECC DIMMs for the module to function.

Questions about this item

Will this 32GB DDR5 module fit a standard desktop motherboard?

It uses the 288-pin UDIMM form factor used by most desktop DDR5 boards. Verify your motherboard supports ECC unbuffered DDR5 at 4800 MT/s and 1.1 V.

Does the ECC feature work on consumer CPUs?

ECC operates only when the CPU and chipset both support it. Many consumer platforms ignore ECC; check your processor and motherboard specifications before relying on error correction.

Is a heat spreader required for this memory?

The module ships without a heat spreader. In typical workstation or NAS chassis with adequate airflow the bare PCB runs within JEDEC thermal limits.
