System-Specific DDR5 RDIMM Kit

This NEMIX RAM kit delivers 64 GB across two 32 GB DDR5 4800 registered DIMMs built for the ASUS RS520A-E12-RS24U server. ECC and registered buffering protect data integrity in mission-critical workloads. Modules run at 1.10 V with CL40 timing and use major OEM chips from Samsung, Micron or Hynix. The 288-pin form factor matches the platform’s memory slots exactly.

Suited for single-socket 2U server upgrades

Administrators expanding memory in the named ASUS 2U server will find direct compatibility and validated stability. Buyers who need unbuffered UDIMMs, non-ECC modules, lower latency ratings, heat spreaders, or capacities beyond the 64 GB supplied here should look at other products. The kit does not support desktop or laptop platforms.

DDR5 4800 registered ECC specification

The decisive attribute is the DDR5 4800 registered ECC RDIMM design with 1Rx4 organisation. This combination determines whether the module fits the server’s memory controller and meets its error-correction requirements. Verify the platform demands registered ECC DDR5 at 4800 MT/s before ordering.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots on the ASUS RS520A-E12-RS24U server?

Yes, the kit contains two 288-pin DDR5 RDIMM modules designed for the ASUS RS520A-E12-RS24U server motherboard.

Do I need to populate specific DIMM slots on the motherboard when installing this 64GB kit?

Install the two 32GB modules in the channels recommended by the ASUS RS520A-E12-RS24U manual to enable dual-channel operation.

Should I expect to replace the modules if the server workload increases beyond the current 4800MT/s speed?

The modules run at DDR5 4800 with CL40 latency; if future workloads require higher speeds, faster DDR5 RDIMMs would be needed.
