16 GB DDR4 ECC registered RDIMM running at 2933 MHz with 1.2 V operation for Dell-compatible servers
This module delivers 16GB of DDR4-2933 registered ECC memory in a 288-pin RDIMM form factor. It operates at 1.2V with a 2Rx8 rank organisation and is built with major-brand DRAM chips. The part is validated as a direct replacement for Dell PN SNPTFYHPC/16VXR.
IT teams maintaining Dell PowerEdge platforms that require PC4-23466 registered DIMMs will find this module a drop-in fit. Workstations or desktops that accept only unbuffered non-ECC UDIMMs cannot use this part, and systems limited to lower DDR4 speeds will not gain the rated frequency.
The module runs at 2933 MT/s with a PC4-23466 data rate; the memory controller must support this exact speed and registered ECC operation. If the platform caps memory at a lower DDR4 frequency or requires unbuffered DIMMs, the module will not function as intended.

Enter the server BIOS or UEFI at boot and confirm the memory summary shows 16 GB at 2933 MT/s with ECC active; the operating system should then report the same capacity and speed without correctable errors.
The box contains the single 288-pin 16 GB 2Rx8 registered DIMM; no cables, brackets, or additional hardware are included, so any required cooling shrouds or riser cards must be obtained from the server vendor.
Select this 16 GB 2Rx8 module when the platform calls for a PC4-23466 ECC registered DIMM; match the total capacity to the number of populated slots your motherboard supports.
