64GB DDR5 ECC registered server module

This is a single 64GB DDR5 4800 ECC registered DIMM built for the ASUS RS700A-E12-RS4U 1U dual-processor server. It operates at 1.1V with a CL40 latency and uses a 2Rx4 organisation across 288 pins. The module is validated for that specific platform.

Suited for capacity upgrades on the named ASUS 1U

Administrators expanding memory in the RS700A-E12-RS4U can install this module directly. Builders working with other server models, desktop boards or non-ECC platforms should look elsewhere because the registered ECC design and platform qualification are specific to this system.

Registered ECC DDR5 with 2Rx4 organisation

The registered buffer and on-die ECC provide the signal integrity and error correction required by the target server. Systems that require unbuffered non-ECC memory or a different rank configuration will not accept this module.

Questions about this item

What does the 4800 MT/s rating mean once this module is installed in a server?

The module will run at up to 4800 MT/s when the server's memory controller is configured for DDR5-4800 operation, delivering PC5-38400 bandwidth per channel.

How does the DDR5 RDIMM interface affect usable bandwidth in this system?

The 288-pin registered DDR5 interface adds a clock cycle for command buffering, capping practical throughput to the PC5-38400 limit while providing the signal integrity required for multi-module configurations.

What physical slot and clearance does this 64 GB stick require?

It needs a standard 288-pin DDR5 RDIMM socket and fits the ASUS RS700A-E12-RS4U 1U chassis; the module has no heat spreader, so low-profile clearance is sufficient.
