Targeted Server Upgrade

This 32GB kit delivers two 16GB DDR4 registered DIMMs built for ASUS Z10PA-U8, Z10PE-D16, Z10PE-D16 WS and Z10PE-D16/10G-2T motherboards. ECC and registered buffering protect data integrity in multi-socket server workloads. The modules run at 2400MHz with CL17 timing at 1.2V. Buyers needing consumer desktop memory or unbuffered DIMMs should look elsewhere.

Kit Composition and Compatibility

The package contains two matched 288-pin sticks totalling 32GB, configured as 2Rx8 for optimal channel population on supported boards. Computer Memory Solutions validates compatibility with the four listed ASUS/ASmobile models only. Systems requiring LRDIMMs, mixed RDIMM and LRDIMM populations, or capacities beyond 512GB per CPU will not be served by this kit.

Physical Build and Daily Use

Modules ship without heat spreaders, keeping a low profile for dense server chassis and allowing unrestricted airflow across the PCB. Gold-plated 288-pin edges ensure reliable contact through repeated seating cycles. Registered signalling reduces electrical load on the memory controller, supporting stable operation across all populated slots in dual-CPU configurations.

Questions about this item

Will the registered ECC modules need any firmware updates or reconfiguration if I later expand to the board's 512 GB maximum?

The motherboard supports up to 512 GB with ECC RDIMMs across 16 sockets using two CPUs; adding identical 2Rx8 registered DIMMs requires no firmware change, only populated slots matching the CPU configuration.

What electrical or thermal limit appears first when all eight channels per CPU run at 2400 MHz continuously?

Each module draws 1.2 V at DDR4-2400 with CL17 timing; the registered buffer and 2Rx8 organisation keep signal integrity within spec, so the platform's memory-controller thermal envelope is reached before any module-level limit.

How much extra heat and fan noise should I expect from the two 16 GB sticks during all-day compute loads?

The sticks have no heat spreader and operate at standard 1.2 V DDR4 voltage; power draw stays within JEDEC limits for registered DIMMs, so case airflow designed for the Z10PE-D16 series handles the additional thermal load without audible fan-speed increase.
