8GB DDR5 4800 Desktop Module

This A-Tech module adds 8GB of DDR5 memory to a desktop system that requires a 4800MHz PC5-38400 DIMM. It is built as a direct replacement for the IBM 4X71N34263 part number and uses major-brand DRAM ICs for reliable operation.

Installation and common issues

The 288-pin DIMM seats in a standard DDR5 slot with no extra cables or drivers. Common problems include the module not clicking fully into the latch, mixing ranks that prevent the system from posting, or the BIOS defaulting to a lower speed until the correct profile is enabled.

1Rx16 rank configuration

This stick uses a single-rank 1Rx16 organisation, which determines how the memory controller addresses the chips. Verify that your platform supports 1Rx16 modules at 4800MHz before purchase, as some boards require a different rank layout for stability.
