OWC 3U2D42R816GB 16GB DDR4 3200 CL22 1.2V 288pin UDIMM Dell OptiPlex 5080 5090 7000 7071

SKU CH-3T9Y-K91NX

16 GB DDR4 3200 CL22 UDIMM for Dell OptiPlex 5080, 5090, 7000 and 7071

  • Capacity16GB
  • Type288-Pin DDR4 Non-ECC UDIMM
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.2V
  • ECCNo
  • Boosts system responsiveness with 16GB DDR4 3200MHz CL22 memory
  • Guaranteed fit for Dell OptiPlex 5080 5090 7000 7071 models
  • JEDEC and RoHS compliant for warranty-safe upgrades
  • Low 1.2V operation reduces power draw and heat
  • Backward compatible with 2133 2400 2666 2933MHz systems

Compatible Dell OptiPlex DDR4 upgrade

This 16GB DDR4 3200 module is built for Dell OptiPlex 5080 Tower, 5090 SFF, 5090 Tower, 7000 SFF and 7071 Tower systems. It delivers a straightforward capacity increase for office workstations that need more memory headroom. The JEDEC standard PC4-25600 specification ensures reliable operation at the platform's rated speed.

Standard 288-pin UDIMM with no heat spreader

The unbuffered non-ECC DIMM uses a 1.2V operating voltage and CL22 timings. Its plain green PCB fits the tight clearances inside small form factor OptiPlex chassis without blocking adjacent slots or CPU coolers. Installation follows the usual tool-free DIMM latch mechanism found on these motherboards.

Replaces slower DDR4 or fills empty slots

The module runs at 3200MHz and is backward compatible with 2133, 2400, 2666 and 2933MHz systems, so it works in older OptiPlex units that officially support lower speeds. The upgrade is worth it when the current configuration has less than 16GB per channel or when all slots are populated with slower modules. Builders who need ECC error correction or registered buffering should look elsewhere.

Questions about this item

Does the DDR4 3200 PC4-25600 standard limit the speed if my Dell OptiPlex 5080 Tower only supports 2666 MHz?

The module runs at the highest speed the platform allows; it is backward compatible with 2133, 2400, 2666 and 2933 MHz systems.

Will the 288-pin 16 GB UDIMM fit inside a Dell OptiPlex 7000 SFF chassis?

Yes, the standard 288-pin UDIMM form factor matches the DIMM slots in the OptiPlex 7000 SFF and the other listed models.

What is the correct way to seat the 1.2 V CL22 DIMM so the system recognises the full 16 GB?

Align the notch with the slot key, press down firmly until both side clips click shut, then power on to verify 16 GB in BIOS.
