OWC 16GB DDR4 2666 CL19 2Rx8 VLP ECC UDIMM 1.2V 288-pin memory upgrade

SKU CH-XEC4-K7CRN

16GB DDR4 2666 ECC VLP UDIMM adds registered-style error correction to compatible Supermicro motherboards

  • Capacity16GB
  • Type288-Pin DDR4 ECC VLP UDIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V
  • ECCYes
  • 16 GB capacity lets you run more applications simultaneously
  • DDR4 2666 speed with CL19 latency delivers responsive data access
  • ECC protection detects and corrects single-bit errors automatically
  • 2 V operation reduces power draw and heat output
  • Validated for Supermicro X11SSZ-F, X11SSZ-TLN4F, X11SSW-4TF, X11SSW-F and X11SSW-TF motherboards

Targeted Server Upgrade

This 16 GB DDR4 module is built for specific Supermicro X11 motherboards including the X11SSZ-F and X11SSW series. It delivers ECC protection and unbuffered operation in a single DIMM for straightforward capacity expansion.

Thermals and Power

Low-profile height and 1.2 V operation keep heat output minimal inside dense chassis. JEDEC-standard timings at CL19 ensure stable throughput without raising fan speeds or power draw.

Compatibility Limits

The kit suits owners of the listed Supermicro boards who need ECC UDIMM memory; it will not fit systems requiring registered DIMMs, non-ECC modules, or a different DDR generation. Buyers needing higher densities per slot or faster JEDEC speeds must select alternative modules.

Perguntas sobre este artigo

How do I install this 288-pin DDR4 VLP ECC UDIMM in a Supermicro X11SSZ-F, and what step is often missed?

Align the notch on the module with the slot key, press down firmly until both side clips click shut, then verify in BIOS that all 16GB are recognised at 2666 MT/s.

What maintenance or replacement will this 16GB DDR4 2666 CL19 module need over its service life?

No routine maintenance is required; keep the slot contacts dust-free and replace the DIMM only if memory diagnostics report correctable or uncorrectable ECC errors.

What limit appears first when this 2Rx8 1.2V DDR4 2666 module runs sustained workloads on a Supermicro X11SSW-F?

The JEDEC-standard 1.2 V operating voltage and CL19 latency define the thermal and timing envelope; sustained loads stay within spec without throttling.
