OWC 16GB DDR4 2666 ECC VLP UDIMM
This 16GB DDR4 2666 module adds ECC protection to compatible Supermicro SuperWorkstation and SuperServer systems. It runs at PC4-21300 speed with CL19 latency and operates at 1.2V in a very low-profile unbuffered DIMM format. The single 2Rx8 rank design fits space-constrained mid-tower chassis.
Capacity and headroom for ECC workloads
The 16GB capacity supports larger datasets and more concurrent virtual machines than 8GB configurations. JEDEC-standard DDR4 2666 bandwidth handles typical workstation memory pressure, while ECC corrects single-bit errors that can corrupt calculations. The module reaches its limit when applications demand more than 16GB per slot or require registered buffering for higher densities.
Upgrade path for Supermicro 5039 and 5019 systems
This module replaces lower-capacity DDR4 ECC UDIMMs in Supermicro SuperWorkstation 5039A-iL, 5039C-I, 5039C-T and SuperServer 5019S-WR, 5019S-MN4 platforms. The jump is worthwhile when current memory falls short of workload requirements or when mixing capacities degrades channel performance. Systems already populated with matched 16GB modules gain no benefit from this single-stick addition.

Questions about this item
Will this 288-pin DDR4 2666 CL19 ECC VLP UDIMM run alongside my existing 2Rx8 modules in a Supermicro 5039A-iL?
Yes — the module is tested for the Supermicro SuperWorkstation 5039A-iL and matches the DDR4 2666 PC4-21300 CL19 2Rx8 1.2 V specification, so it will operate with identical DIMMs in that system.
How can I verify the 16 GB stick is recognised at 2666 MT/s with ECC active after installation?
Enter the system BIOS or UEFI on the Supermicro 5039 series and confirm the memory shows 16 GB, 2666 MT/s, CL19 timing and ECC enabled.
Does the 2E6V42R816GB package include only the single 16 GB VLP UDIMM or are any tools or cables supplied?
The upgrade consists of one 16 GB DDR4 2666 CL19 2Rx8 1.2 V VLP ECC unbuffered DIMM; no tools, cables or additional hardware are included.
