Dell Precision 3660 upgrade kit

This 64GB kit contains two 32GB DDR5 modules built for the Dell Precision 3660 tower workstation. It targets professionals who need more memory capacity for large datasets or virtual machines. The modules run at 4800 MT/s with CL40 latency at 1.1V.

288-pin UDIMM form factor

Unbuffered non-ECC DDR5 UDIMMs install directly into the workstation's standard DIMM slots without registration buffers. The 2Rx8 organisation uses major OEM chips from Samsung, Micron or Hynix. No heat spreader is fitted, so clearance inside the chassis remains unchanged.

Lifetime replacement warranty included

The package supplies only the two memory modules and no additional cables, brackets or software media. NEMIX RAM stress-tests every module under load before shipping and backs the kit with a lifetime replacement warranty supported by their IT support team.

Questions about this item

What DDR5 speed and PC5 rating does this 64 GB kit run at?

The kit operates at DDR5 4800 with a PC5-38400 data rate, which is the standard JEDEC speed for this platform.

What physical slot count and pin layout must the Dell Precision 3660 have for these modules?

Each module is a 288-pin DDR5 UDIMM; the workstation needs two free UDIMM slots to accept the 2 x 32 GB kit.

How are the modules installed in the Precision 3660, and what step is often missed?

Power off, open the chassis, align the notch on each 288-pin UDIMM with the slot key, press firmly until both retention clips click, then close the case and power on.
