Kit composition and target system

This 128GB kit contains four 32GB DDR4 SO-DIMM modules designed for Dell Precision 17 7000 Series (7730) and Precision Mobile Workstation 7530. It suits professionals upgrading compatible mobile workstations to the maximum supported capacity. Buyers with laptops limited to fewer than four slots or a lower ceiling cannot use the full kit.

Speed grade and form factor

Each module runs at DDR4 2666 (PC4 21300) with CL19 19-19-19 timing at 1.2V in a 260-pin unbuffered non-ECC package. The 2Rx8 organisation matches the processor memory controller requirements for these models. Systems that demand ECC or a different voltage will not work with this kit.

Installation context

Four slots must be free to install the complete set; mixing with existing sticks forces all memory to the slowest installed speed. A 64-bit operating system is required to address more than 4GB. Builders needing ECC registered memory for Xeon configurations should select a different product.

Questions about this item

Will the 2666 MHz speed run at that rate in a Dell Precision 7730?

The kit is rated DDR4 2666 (PC4 21300); the Precision 7730 and 7530 support that speed, so the modules will operate at 2666 MHz provided the processor and BIOS allow it.

Is the 260-pin DDR4 SO-DIMM interface the only thing that determines fit in the 7530?

The 260-pin SO-DIMM form factor matches the laptop slots, but the system also requires non-ECC unbuffered modules; this kit meets both requirements for the listed Precision models.

Does the 32 GB per stick, 2Rx8 layout fit the four SODIMM sockets in the 7730?

Yes — the Precision 7730 and 7530 have four SODIMM slots, and each 32 GB 2Rx8 module occupies one slot, filling all four for the full 128 GB capacity.
