16 GB DDR4-3200 ECC UDIMM module with 2Rx8 organisation for HP-compatible servers
This 16GB DDR4 module is built as a direct equivalent to HP part 141H4AA for server and workstation upgrades. It targets administrators who need validated ECC memory without purchasing vendor-labelled kits.
The stick runs at 3200 MT/s under the PC4-25600 standard and uses a 2Rx8 organisation. System bus limits or mixed-rank populations can force the module down to lower JEDEC speeds, so total throughput depends on the host platform.
As a standard UDIMM it fits any DDR4 UDIMM slot, but ECC only functions on platforms that explicitly support error correction. Mixing ranks or exceeding the board’s maximum module count are the most common reasons the memory fails to initialise.

The product name lists 1Rx8 while the supplier title shows 2Rx8. Both are 16GB DDR4-3200 ECC UDIMMs, but rank organisation differs. Check your server manual for the supported rank configuration before ordering.
The module runs at DDR4-3200 (PC4-25600) with ECC error correction. Real-world throughput depends on the platform memory controller, channel population and BIOS settings; the rated speed is the maximum JEDEC standard frequency for this DDR4 part.
UDIMM means unbuffered DDR4. The 16GB capacity and 3200Mhz rating are the module specifications. Maximum supported capacity per slot and achievable speed are determined by the specific HP server model and its memory controller.
