Compatible Dell Tower Upgrade

This 32 GB kit contains two 16 GB DDR4 modules rated at 2666 MHz with CL19 timings. It is built for the Dell OptiPlex 7071 Tower and Precision Workstation 5820 using Intel Pentium processors. The unbuffered, non-ECC DIMMs install directly into the system's 288-pin slots.

2666 MHz DDR4 Speed Match

The single specification that decides fit is the DDR4 2666 (PC4 21300) speed grade. Your Dell platform must support this exact data rate; faster or slower modules will force the memory controller to run at the lowest common speed. Verify the CPU and chipset accept 2666 MHz before purchase.

Matched Pair For Dual Channel

The bundle supplies two identical 16 GB sticks so the board can run in dual-channel mode, doubling memory bandwidth versus a single module. All modules in the system will operate at the slowest installed speed, so mixing with existing slower RAM reduces the benefit of this kit. A 64-bit operating system is required to address the full 32 GB capacity.

Questions about this item

What does the 2666 MHz speed mean once the modules are installed in my Dell OptiPlex 7071 Tower?

The system will run the memory at 2666 MHz, delivering PC4-21300 bandwidth as long as the processor supports that data rate.

How does the 288-pin DDR4 interface affect what I can install alongside these sticks?

They fit any standard 288-pin DDR4 DIMM slot, but all installed memory will operate at the speed of the slowest module or the CPU limit.

Will the 2Rx8 rank layout and 1.20 V voltage fit the four slots in a Precision Workstation 5820?

Yes, each 16 GB stick uses a 2Rx8 organisation at 1.20 V, matching the workstation's four DIMM sockets for a 32 GB total.
