OWC 32GB DDR4 2666MHz CL19 1.2V 288-Pin UDIMM for Dell Precision 3930 5820

32 GB DDR4 2666 MHz for Dell Precision 3930 and 5820

This 32 GB DDR4 2666 MHz CL19 UDIMM is built for Dell Precision 3930 and 5820 workstations. It suits professionals who need more memory for multitasking, large datasets or virtual machines. The module follows JEDEC standard specifications and runs at 1.2 V without ECC or a heat spreader.

Simple DIY installation with backward compatibility

Installation is a straightforward DIY task that only requires seating the 288-pin module into an available DIMM slot. The stick is backward compatible with 2133 MHz and 2400 MHz systems, so it will downclock automatically if the platform demands a lower speed. The main risk is mixing non-ECC memory with ECC-only slots or exceeding the workstation's maximum supported capacity per channel.

DDR4 2666 MHz limits and platform constraints

The DDR4 2666 MHz interface caps bandwidth at the PC4-21300 rate, so workloads that scale with memory throughput will hit that ceiling. The module operates at 1.2 V and CL19 latency, which are fixed by the JEDEC profile. Systems that require registered or ECC DIMMs cannot use this unbuffered non-ECC kit, and the total capacity is limited by the motherboard's slot count and chipset maximum.
