Precision Workstation Memory Upgrade

This single 32GB DDR5 SODIMM is built for Dell Precision 3470 3571 3581 5570 and 5770 mobile workstations. It targets professionals who need more capacity for multitasking large datasets or creative projects. The module is a direct replacement for Dell part numbers 949335 258276 and others. Buyers with non-Precision laptops or desktops should verify compatibility before purchasing.

Thermals and Power Profile

Operating at 1.1V the module follows the standard DDR5 voltage for low power draw in thin-and-light chassis. No heat spreader is fitted so the design relies on the laptop's existing cooling airflow. The unbuffered non-ECC layout adds no extra electrical load. Systems without a user-accessible SODIMM slot cannot use this upgrade.

Deciding Specification

The 4800 MT/s CL40 JEDEC speed rating is the single figure that determines whether this module matches the platform memory controller. It runs at PC5-38400 with 2Rx8 organisation and 262-pin form factor. A different speed grade or latency would not be supported by the listed Precision models.

商品問答

How do I install the 262-pin SODIMM in a Precision 5570 and what step is often missed?

Power off the laptop, remove the base cover, insert the module at an angle into the DDR5 slot until the clips click, then refit the cover before powering on. The step often missed is pressing firmly enough for both retention clips to engage fully.

Will this 32 GB DDR5 module need any maintenance or replacement during the laptop's life?

The module is a non-ECC unbuffered DDR5 SODIMM with no moving parts and no heat spreader, so it requires no scheduled maintenance. Replacement is only needed if a memory error appears or the system is upgraded beyond 32 GB.

What limit appears first when the Precision 3581 runs sustained workloads with this CL40 4800 MT/s memory?

The CAS latency of CL40 at 4800 MT/s sets the baseline access delay; under sustained load the memory controller's thermal throttling or the module's 1.1 V voltage ceiling typically limits throughput before the rated speed is reached.
