32 GB DDR5 ECC UDIMM for servers

This 32 GB DDR5 4800 module brings ECC protection to unbuffered server and workstation boards. It runs at the standard 1.10 V and uses a 2Rx8 organisation with Samsung chips. The single DIMM suits admins who need capacity growth without registered memory overhead.

262 pin DIMM installs in standard DDR5 slots

The module fits any 262 pin DDR5 UDIMM socket; alignment is keyed so it cannot be inserted backwards. Common issues arise when the platform BIOS lacks support for 2Rx8 EC4 density or when mixed ranks prevent training at 4800 MT/s. Verify the qualified vendor list before seating the DIMM.

Sustained 4800 MT/s throughput with CL40 latency

Under continuous load the DRAM maintains its rated 4800 MT/s data rate and CL40 timing without throttling. ECC corrects single bit errors on the fly, preserving data integrity during long compute runs. The 1.10 V operation keeps thermals predictable in densely populated channels.

Questions about this item

How can I verify the 32GB DDR5 4800 module is running at CL40 and 1.10V after installation?

Enter the system BIOS or UEFI and open the memory information screen; it will show the detected speed as 4800 MT/s, CAS latency as CL40 and voltage as 1.10V if the module is operating to specification.

What exactly ships in the box and do I need any extra parts to install this 288-pin UDIMM?

The package contains one 32GB DDR5 4800 ECC UDIMM module; no additional cables, brackets or cooling parts are required for installation in a compatible 288-pin DIMM slot.

Should I choose the 2Rx8 EC4 version or a different rank configuration for my server board?

Select this 2Rx8 EC4 module when your server or workstation documentation specifies a dual-rank unbuffered ECC DIMM; the rank and ECC type must match the platform's qualified memory list.
