Dell Precision M4600 M6600 upgrade

This 4GB DDR3 SODIMM is built for Dell Precision M4600 and M6600 mobile workstations. It provides a direct, single-module memory increase for professionals who need more headroom in those specific systems. The module arrives new and ready to install without configuration changes.

DDR3 1600 PC3-12800 limits

The DDR3 1600 interface caps bandwidth at PC3-12800 with CL11 latency at 1.5V. JEDEC compliance guarantees electrical compatibility, but the standard itself cannot exceed this speed or voltage envelope. Systems that require ECC, registered signalling, or higher DDR generations will not accept this module.

4GB single-rank capacity

A single 1Rx8 4GB stick suits light multitasking and typical office workloads on the supported Precision models. Larger datasets, virtual machines, or memory-intensive creative applications will exhaust this capacity quickly. Buyers who need more than 4GB per slot must look beyond this module.

Questions about this item

Which capacity should I pick for my Dell Precision M4600 or M6600?

This module is a single 4GB DDR3 1600 SODIMM; add one or more to reach the total memory your workload needs.

What does the DDR3 1600 CL11 rating mean once installed?

It runs at 1600 MHz with CAS latency 11, giving the CPU quicker access to data than slower DDR3 modules.

Will the 204-pin SODIMM fit and run at the rated speed in my Precision laptop?

Yes — it is a 204-pin DDR3 SODIMM specified for the M4600 and M6600, so it seats correctly and operates at 1600 MHz.
