32 GB DDR4 Kit for Dell OptiPlex and XPS

This 32 GB kit contains two 16 GB DDR4 DIMMs rated at 2666 MHz with CL19 timing. It is built for the Dell OptiPlex XE3 Small Form Factor and the XPS 8930 desktop. The modules are unbuffered, non-ECC and run at 1.2 V.

DDR4 2666 Speed and Four-Slot Limit

The memory uses the DDR4 2666 (PC4 21300) standard across 288 pins. The supported platforms provide four memory sockets with a maximum system capacity of 64 GB. All installed modules operate at the speed of the slowest module or the processor limit.

Dual-Rank 16 GB Modules and 64 GB Ceiling

Each 16 GB stick uses a 2Rx8 organisation, giving two ranks per module. A pair fills half the slots and leaves room for a second matched pair to reach the 64 GB ceiling. Systems needing more than 64 GB or requiring ECC cannot use this kit.

Domande su questo articolo

Should I choose the 32 GB kit or aim for the 64 GB maximum?

The kit provides 32 GB using two 16 GB modules; the platform supports up to 64 GB across four slots, so adding a second identical kit later will reach the maximum.

What does the 2666 MHz rating deliver in daily use?

At 2666 MHz with CL19 timing the modules transfer data at the PC4-21300 rate, giving responsive multitasking and smooth application switching on the supported Dell desktops.

Will the 288-pin DDR4 interface work at full speed in my OptiPlex XE3 SFF?

Yes, the 288-pin DDR4 DIMMs are designed for the OptiPlex XE3 SFF and XPS 8930 and will run at the rated 2666 MHz without manual configuration.
