16GB DDR4 SODIMM for Dell Precision workstations

This 16GB DDR4 3200 module is built for Dell Precision 7550, 7560, 7730, 7740 and 7750 mobile workstations. It targets professionals who need a straightforward memory upgrade to run larger datasets or more simultaneous applications. The 260-pin SODIMM form factor fits the factory memory slots in these specific models.

DDR4 3200 JEDEC standard limits peak bandwidth

The memory operates at the JEDEC DDR4 3200 (PC4-25600) standard with CL22 latency and 1.2V voltage. This specification caps the maximum theoretical throughput at the rated speed; the module cannot exceed the standard DDR4 3200 data rate. Systems that only support lower DDR4 speeds will downclock the module automatically.

Non-ECC unbuffered design rules out ECC-required

The module is a non-ECC, unbuffered 2Rx8 SODIMM without a heat spreader. It will not satisfy configurations that require error-correcting code or registered memory. Buyers whose Precision workstations mandate ECC or registered DIMMs must choose a different part.

Questions about this item

Should I pick the 16 GB module or a different capacity?

This part number is a single 16 GB SODIMM; choose it when you need exactly that amount or want to add 16 GB to an empty slot.

What does the 3200 speed rating mean once installed in my Precision?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2 V, delivering the rated throughput provided the laptop’s memory controller supports that frequency.

Which memory standard and pin count does this SODIMM use?

It is a 260-pin DDR4 Non-ECC SODIMM built to JEDEC specifications for the listed Dell Precision models.
