System-Specific DDR5 Upgrade

This 192 GB kit contains six 32 GB DDR5 4800 CL40 ECC registered DIMMs built for the ASUS RS520A-E12-RS24U 2U server. It targets administrators who need maximum registered capacity in that platform.

Compatibility Check

Verify that your RS520A-E12-RS24U has six free 288-pin DDR5 slots and that the BIOS revision supports 1Rx4 registered modules at 1.10 V. The kit is validated only for this single-socket 2U model.

Thermals and Power

Bare modules without heat spreaders rely on the server’s directed airflow; power draw stays at the standard 1.10 V DDR5 level. Acoustic impact is determined by the chassis fans, not the memory itself.

Questions about this item

Does the kit include all six 32 GB modules or must any be purchased separately?

The package contains the full 192 GB kit — six 32 GB DDR5 4800 CL40 ECC registered DIMMs — so nothing else needs to be bought for this capacity.

Why choose the 1Rx4 32 GB rank over other ranks for the RS520A-E12-RS24U?

The 1Rx4 organisation keeps each module at a single rank, allowing all twelve slots to be populated while staying within the server's rank-per-channel limits.

What does the 4800 MT/s rating deliver once the memory is installed in the ASUS RS520A-E12-RS24U?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.10 V, providing the maximum standard speed the platform supports without overclocking.
