32GB DDR4 SODIMM kit for Dell Precision 7540

This 32GB kit contains two 16GB DDR4 2666MHz SODIMM modules built to the PC4 21300 standard. They run at 1.2V with CL19 19-19-19 timings in an unbuffered, non-ECC 2Rx8 configuration. The 260-pin form factor fits the Dell Precision Mobile Workstation 7540 and 7740.

Matched pair ensures dual-channel operation

The two modules are sold as a matched kit so the workstation can run in dual-channel mode. Mixing with existing memory will force all modules to operate at the slowest installed speed or the processor limit. A 64-bit operating system is required to address the full 32GB capacity.

Suits owners upgrading compatible Dell Precision

Builders needing ECC memory for Xeon processors should choose a different module because this kit is non-ECC. Systems limited to lower speeds or fewer than two slots will not use the full specification. Buyers who want more than 32GB must add modules to the remaining two sockets up to the 128GB maximum.

Questions about this item

Will the 2Rx8 DDR4 modules need any firmware updates or periodic reseating over their lifespan?

No firmware or reseating is required; the 2Rx8 DDR4 modules run at 1.2V with a limited lifetime warranty against manufacturing defects.

What speed ceiling will the 2666MHz kit hit first when the Precision 7540 or 7740 is under continuous load?

All installed memory runs at the slowest module or CPU capability; mixing speeds forces the 2666MHz kit to down-clock to the lowest common rate.

How much extra heat or fan noise do two 16GB 1.2V sticks add during all-day workstation use?

The unbuffered 1.2V SODIMMs have no heat spreader and draw minimal power, so they add negligible heat or acoustic load inside the chassis.
