Server Memory Kit

This A-Tech kit supplies 64GB of DDR5 server memory across two 32GB unbuffered ECC modules. It targets administrators upgrading compatible DDR5 servers or workstations that require error-correcting UDIMMs. The dual-channel pair is built with major-brand DRAM ICs and operates at the standard 1.10V. Desktop and laptop systems cannot use these modules.

ECC UDIMM Compatibility

The decisive specification is the EC4 UDIMM format with 2Rx8 dual-rank organisation. Only platforms that explicitly support DDR5 ECC unbuffered DIMMs at this density and rank structure will accept the kit. Verify the motherboard or system manual for qualified memory lists before installation. No heat spreader is fitted on the modules.

Sustained Workload Behaviour

Rated at DDR5-5600 with a CAS latency of 40, the modules deliver consistent throughput under continuous multi-threaded loads typical of virtualization and database tasks. ECC correction maintains data integrity during extended operation without the buffering overhead of registered DIMMs. The 1.10V standard voltage keeps power draw predictable across all populated channels.

Questions about this item

How does the DDR5-5600 speed translate to real-world throughput in a server?

The modules run at 5600 MT/s, delivering up to 44800 MB/s of bandwidth per channel when installed in a compatible DDR5 server platform.

What does the PC5-44800E designation mean for ECC UDIMM compatibility?

PC5-44800E identifies the kit as ECC unbuffered DDR5 rated for 5600 MT/s; it fits only motherboards that explicitly support EC4 UDIMM memory.

What physical slot and clearance do the 288-pin DIMMs require?

Each 32 GB module uses a standard 288-pin DDR5 DIMM edge connector and has no heat spreader, so it fits any UDIMM slot with normal height clearance.
