64GB DDR5 4800 ECC RDIMM module

This 64GB DDR5 4800 ECC RDIMM module provides registered server memory for the ASUS RS520A-E12-RS12U. It operates at 1.1V with CL40 latency and uses a 2Rx4 organisation. The 288-pin design fits the server's DDR5 slots directly.

For single-socket 2U ASUS servers only

This module suits administrators expanding memory in the RS520A-E12-RS12U platform. It does not suit builds needing unbuffered UDIMM modules or systems that cannot address a 64GB registered DIMM. Buyers requiring non-ECC memory should look elsewhere.

64GB capacity per DIMM

The single 64GB density determines how many modules are needed to reach the target system memory. Each DIMM delivers 64GB at DDR5 4800 speed with ECC and registered signalling. Verify the server's maximum supported capacity per slot before ordering.

Questions about this item

Should I pick the single 64GB module or look for a multi-stick kit?

This part number ships as one 64GB stick. The RS520A-E12-RS12U has 12 DDR5 slots, so you can add more identical modules later to fill the remaining bays.

What does the 4800 MT/s rating deliver inside an ASUS RS520A-E12-RS12U?

The server's memory controller runs DDR5 at 4800 MT/s by default, so this module operates at its rated PC5-38400 bandwidth without overclocking.

How does the 288-pin RDIMM interface limit what I can install?

The 288-pin registered DIMM slot only accepts DDR5 RDIMM modules; unbuffered UDIMMs or other DDR generations will not fit or function.
