OWC 16GB DDR4 2666MHz UDIMM

This 16GB DDR4 module runs at 2666MHz with a CL19 latency and 1.2V operation. It uses a 288-pin unbuffered non-ECC UDIMM form factor and is validated for Dell Precision 3930 and 5820 workstations.

Suits Precision 3930 and 5820 upgrades

Builders expanding memory in a Dell Precision 3930 or 5820 will find this module a direct fit. Systems requiring ECC error correction or registered DIMMs cannot use this non-ECC unbuffered kit.

2666MHz DDR4 speed rating

The PC4-21300 2666MHz CL19 specification determines whether the module matches the platform's supported memory bus; systems limited to lower speeds will downclock automatically.

Soalan tentang produk ini

Does the PC4-21300 2666MHz DDR4 interface limit speed to 2666MHz in a Dell Precision 3930?

Yes, the module runs at 2666MHz CL19 and is backward compatible with 2133MHz and 2400MHz systems, so the Dell Precision 3930 will operate it at its rated 2666MHz speed.

Will the 288-pin unbuffered UDIMM fit the Dell Precision 5820 motherboard slots?

Yes, the 288-pin DDR4 UDIMM form factor matches the DIMM slots on the Dell Precision 5820 and 3930 workstations.

How is the OWC 16GB DDR4 module installed, and what step do people often miss?

Power off the workstation, open the chassis, align the notch on the 288-pin UDIMM with the slot key, press firmly until both side clips click, then verify 16GB appears in BIOS.
