A-Tech 32GB DDR5 4800 ECC RDIMM

This 32 GB DDR5 module runs at 4800 MHz with CL40 latency and 1.10 V operation. It uses a 2Rx8 registered ECC design on a 288-pin RDIMM form factor. The Hynix HMCG88MEBRA chipset is Supermicro certified for server platforms.

Suits registered ECC server boards only

This module fits systems that require DDR5 registered ECC RDIMMs with 2Rx8 organisation. It will not work in desktops or laptops that accept only unbuffered non-ECC memory. Buyers needing unbuffered DIMMs should look at a different product line.

2Rx8 registered ECC architecture

The dual-rank registered layout with on-die ECC is the single specification that determines compatibility. Your motherboard and CPU must explicitly support DDR5 RDIMM ECC memory with this rank configuration for the module to function.

Questions about this item

How much heat does the 1.1 V DDR5 4800 module add when running continuously?

The module operates at the standard DDR5 voltage of 1.1 V, which keeps power draw and heat output low during all-day server workloads.

What motherboard slot and memory-channel support are required for this 288-pin RDIMM?

You need a server board with DDR5 RDIMM slots that accept 288-pin registered modules and support the 4800 MT/s data rate.

Can this Supermicro-certified 2Rx8 ECC RDIMM be paired with slower DDR5 registered DIMMs in the same system?

Yes, the module runs at DDR5 4800 CL40; the memory controller will down-clock all installed DIMMs to the speed of the slowest one.
