Server Memory Upgrade

This A-Tech 64GB DDR5 5600 ECC RDIMM module is built for server and workstation platforms that require registered memory with error correction. It uses Micron DRAM chips and runs at the standard DDR5 voltage of 1.10V with a CAS latency of 40.

For Registered ECC Systems Only

The module suits administrators expanding capacity in systems that support 2Rx4 registered DIMMs and need 5600 MT/s operation. It will not work in desktop boards that accept only unbuffered non-ECC memory or in laptops that use SODIMM slots.

No Heat Spreader Included

The bare circuit board relies on chassis airflow for cooling, which is typical for dense server configurations where modules sit in directed air paths. No additional software, cables or mounting hardware are bundled with the single stick.

Questions about this item

Does my server need a DDR5 RDIMM slot to accept this 288-pin module?

Yes, the module is a 288-pin DDR5 RDIMM and requires a server or workstation motherboard with DDR5 registered DIMM slots.

Will this 5600 MT/s ECC RDIMM downclock to match older DDR5 4800 modules I keep installed?

The module runs at 5600 MT/s; if mixed with slower DDR5 modules the system will typically operate all memory at the lowest common speed.

How can I confirm the 64 GB module is running at 5600 MT/s with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify speed shows 5600 MT/s and ECC status reports as enabled.
