Targeted Server Memory Upgrade

This 16GB DDR4 module is built for Supermicro SuperServer 5019C-MHN2, 5029C-T and 5039MC-H8TRF systems. It also fits Supermicro X11SSW-F and X11SSW-TF motherboards. The kit provides a single 288-pin VLP ECC UDIMM for administrators expanding capacity in compatible rackmount or tower servers.

DDR4 2666 JEDEC Limits

The module runs at 2666 MT/s with CL19 latency at the standard 1.2 V JEDEC voltage. ECC protection corrects single-bit errors, which is required for the target Supermicro platforms. Unbuffered 2Rx8 organisation means the memory controller sees two ranks per DIMM; total rank count per channel must stay within the motherboard limit. Builders who need registered or load-reduced DIMMs cannot use this part.

Replaces Lower-Capacity DDR4 DIMMs

Swapping out 8GB or smaller DDR4 2666 sticks for this 16GB module doubles density per slot without changing voltage or speed. The upgrade is worth it when the server hits memory pressure during virtualization, database caching or multi-user workloads. Systems already populated with maximum supported DIMMs per channel cannot accept additional modules.

商品問答

Should I pick the 16GB module or add multiple sticks for my Supermicro SuperServer?

The module is a single 16GB DDR4 2666 stick. OWC recommends matching capacity, speed and manufacturer across all slots, so add identical 16GB modules to reach your desired total.

What does the PC4-21300 rating deliver in my SuperServer 5019C-MHN2?

PC4-21300 means 2666 MT/s peak bandwidth. In your SuperServer the memory will run at that speed with CL19 latency, giving the throughput the platform expects from DDR4 2666 ECC UDIMMs.

Is the 288-pin DDR4 ECC UDIMM keyed differently from registered DIMMs?

Yes. This is a 288-pin unbuffered ECC UDIMM (2Rx8, 1.2 V, VLP). It fits standard DDR4 UDIMM slots on the X11SSW-F and X11SSW-TF boards; registered DIMMs use a different key and will not seat.
