16GB DDR5 4800 ECC RDIMM Server Memory

This A-Tech 16GB DDR5 4800 ECC RDIMM is a registered server memory module built for HP and HPE systems. It operates at 4800MHz with a CAS latency of 40 and a standard 1.10V voltage. The 288-pin DIMM uses a 1Rx8 rank configuration and major brand DRAM chips. It serves as a direct replacement for HP part numbers 340K1AA, P43322-B21, P48499-001 and P43324-0A1.

Suited for HP server upgrades not general desktop

This module fits administrators upgrading compatible HP or HPE servers and workstations that require registered ECC memory. It is not suitable for standard desktop motherboards which typically use unbuffered non-ECC DIMMs. Builders needing higher capacities per slot or different rank configurations should verify their platform requirements before purchase.

Registered ECC DDR5 4800 1Rx8 compatibility

The registered ECC RDIMM design with 1Rx8 organisation is the single specification that determines whether this module works in a given system. Only platforms that explicitly support DDR5 registered ECC memory at 4800MHz with this rank structure can use it. Consult the system manual for approved memory seating and channel guidelines.

Questions about this item

How do I install this 288-pin DDR5 RDIMM and which step is commonly missed?

Align the notch on the module with the slot key, press firmly until both retention clips click, then verify the system detects all 16GB in the BIOS memory map.

What maintenance or replacement will this ECC RDIMM need during its service life?

No scheduled maintenance is required; if a correctable error count rises or the module fails POST, replace the 1Rx8 stick with an identical DDR5 4800 part.

What limit appears first when this 1.10V module runs under sustained load?

The CAS latency of 40 cycles at 4800 MT/s sets the timing ceiling before thermal throttling becomes a factor on this unbuffered heat-spreaderless design.
