Compatible server memory kit

This 192GB DDR5 ECC registered kit is built specifically for the ASUS RS520A-E12-RS24U 2U server. It contains twelve 16GB RDIMM modules rated at 4800MHz with CL40 latency and 1.10V operation. The modules use major OEM chips from Samsung, Micron or Hynix and are stress-tested for stability in mission-critical environments.

Suited for single-socket ASUS 2U servers.

This kit suits administrators upgrading the named ASUS single-socket high-performance 2U server where registered ECC memory is required. It will not fit desktop boards, workstations needing unbuffered DIMMs, or servers that demand a different pin-out, voltage or rank configuration. Buyers without this exact ASUS model should verify their platform's qualified-vendor list before purchasing.

12 modules of 16GB each decide capacity

The single specification that determines fit is the 12x16GB population: it occupies every DIMM slot in the target server and delivers 192GB total capacity. If your chassis has fewer slots, or if your workload needs a different per-module density, this kit will not match the hardware layout.

Questions about this item

Does the 1.10 V operating voltage stay stable during sustained 24/7 server workloads?

Yes, each module is rated at 1.10 V and validated under continuous load for the RS520A-E12-RS24U platform

How much heat do the 12 modules generate when the kit runs at full 4800 speed all day?

The 1Rx8 DDR5 RDIMM modules operate without heat spreaders at standard server airflow and 1.10 V

What motherboard slot configuration is required to install all 12 modules in the RS520A-E12-RS24U?

The 2U server provides 12 DDR5 RDIMM slots, one per 16 GB module, for the full 192 GB kit
