Compatible Dell Precision 3581 upgrade

This 64 GB kit contains two 32 GB DDR5 SODIMM modules built for the Dell Precision 3581 mobile workstation. The memory runs at 5200 MT/s with a CAS latency of CL38 and operates at 1.1 V. It is a non-ECC unbuffered kit using 262-pin 2Rx8 chips from major OEM suppliers.

Suits users filling both Precision 3581 slots

The dual-module kit matches the two-slot layout of the Precision 3581, so buyers wanting a single 32 GB stick or a larger total capacity should look elsewhere. Systems requiring ECC or registered memory are not supported by this unbuffered non-ECC design. Anyone needing a heat spreader will also need a different module.

262-pin DDR5 SODIMM form factor decides fit

The 262-pin DDR5 SODIMM interface is the single specification that determines whether this kit installs in the target laptop. Verify that the Precision 3581 accepts DDR5 SODIMMs before purchase.

Questions about this item

Does the Precision 3581 need two free SODIMM slots to install this 64 GB kit?

Yes, the kit contains two 32 GB modules, so two empty 262-pin DDR5 slots are required for the full 64 GB upgrade.

Can I keep the factory DDR5 5200 modules and add this 2Rx8 kit alongside them?

The Precision 3581 has two SODIMM slots; installing this 64 GB kit means removing any existing modules because both slots will be occupied by the two 32 GB sticks.

How can I verify the new memory is running at DDR5 5200 with CL38 timings after installation?

Open Task Manager or BIOS and confirm the speed reads 5200 MT/s and the CAS latency shows 38; the modules are rated at 1.10 V and 2Rx8 organisation.
