System-specific DDR5 RDIMM kit

This 192GB kit contains six 32GB DDR5 4800 CL40 registered ECC modules built for the ASUS RS520A-E12-RS12U single-socket 2U server. The modules run at 1.10V and use a 1Rx4 organisation with 288-pin RDIMM form factor.

Compatibility and use-case limits

Suitable for administrators upgrading that exact ASUS server model where registered ECC memory is required. Not suitable for desktop boards, workstations needing unbuffered DIMMs, or any system that cannot accept registered DDR5 modules.

Deciding specification: registered ECC DDR5

The modules are DDR5 4800 CL40 registered ECC RDIMMs; only systems designed for registered DDR5 ECC memory can use them. If the target platform requires unbuffered or non-ECC DDR5, this kit will not function.

Questions about this item

Should I buy the 192GB kit or build the same capacity from smaller kits?

The 192GB kit supplies six matched 32GB modules tested together for the ASUS RS520A-E12-RS12U, avoiding mixed-rank or timing issues that can appear when combining separate kits.

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

The server's memory controller runs these DDR5 modules at 4800 MT/s with CL40 latency, providing the rated PC5-38400 bandwidth for ECC-protected workloads.

How does the 288-pin DDR5 RDIMM interface limit what I can install?

Only 288-pin DDR5 RDIMM modules fit the RS520A-E12-RS12U slots; earlier DDR generations or unbuffered DIMMs are physically and electrically incompatible.
