Server memory upgrade

This OWC module is a 16GB DDR4 2666 ECC VLP UDIMM built for Supermicro SuperServer 5019S series systems. It operates at 1.2V with CL19 latency and a 2Rx8 rank configuration. The 288-pin unbuffered design fits the validated server platforms without modification.

ECC unbuffered specification

The single decisive specification is the ECC unbuffered DDR4 2666 (PC4-21300) interface with 2Rx8 organisation. Only systems that accept unbuffered ECC VLP UDIMMs at this speed and rank will recognise the module. Buffered or non-ECC platforms cannot use this part.

Suited for 5019S maintenance

This upgrade suits administrators expanding memory in the listed SuperServer 5019S models where the DIMM slots support 16GB unbuffered ECC VLP modules. Builders needing registered ECC, higher capacities per slot, or non-ECC consumer memory should look at other modules.

商品問答

How does the 2666 MT/s speed translate to real performance in a SuperServer 5019S?

The module runs at 2666 MT/s with CL19 timing, delivering the standard DDR4 2666 data rate once installed in a compatible 5019S system.

What does the PC4-21300 designation mean for bandwidth on this VLP UDIMM?

PC4-21300 is the JEDEC standard name for DDR4 2666, confirming the module meets the official specification for that speed grade.

Will the very-low-profile 288-pin form factor fit the DIMM slots in a SuperServer 5019S chassis?

Yes, the VLP 288-pin UDIMM is built to the exact mechanical and electrical spec required by the listed 5019S models.
