Precision 3660 Tower memory upgrade

This 16GB DDR5 module is built for Dell Precision Workstation 3660 Tower and 3660XE Tower systems. It replaces Dell part numbers AB883074 and AC027075. The kit targets professionals who need a straightforward capacity increase for demanding workloads. It is not suited for servers requiring ECC or registered DIMMs.

DDR5 4800 CL40 1.1V JEDEC standard

The module runs at 4800 MT/s with CL40 latency at the standard 1.1V JEDEC voltage. This single specification decides whether the part matches your platform's supported speed and timing. Systems that only accept slower DDR5 or require different voltage will not operate correctly with this module.

Single 288-pin UDIMM for open slot

The unbuffered 288-pin DIMM installs directly into an available UDIMM slot on the workstation motherboard. No heat spreader is fitted, so clearance is minimal and compatible with standard CPU coolers. The upgrade frees no additional slots beyond the one occupied. Builders needing ECC, registered memory or higher density per module must choose a different part.

Soalan tentang produk ini

What does the 4800 speed rating mean once the module is installed in my Precision 3660 Tower?

The module operates at 4800 MT/s with CL40 latency, matching the JEDEC standard for DDR5 4800 memory on the supported platform.

What interface standard does the 288-pin DDR5 connection use, and what does it cap in practice?

The 288-pin UDIMM follows the JEDEC DDR5 specification, running at 1.1 V with non-ECC unbuffered operation on the Precision 3660 and 3660XE.

What physical slot and clearance does this 1Rx8 UDIMM need to fit in the 3660 Tower?

It installs in a standard 288-pin DDR5 UDIMM slot and has no heat spreader, so it fits within the normal DIMM clearance of the Precision 3660 and 3660XE towers.
