16 GB DDR4 SODIMM for Dell Precision 7760

This 16 GB DDR4 3200 CL22 SODIMM is built specifically for the Dell Precision 7760 mobile workstation. It targets professionals who need a straightforward capacity increase for memory-intensive workloads such as rendering, simulation or large dataset handling. The module follows the exact electrical and physical profile required by that single platform.

Tool-free slot access with one compatibility gate

Installation is a typical DIY step: open the service hatch, align the 260-pin key, press until the latches click, then close the cover. The only common failure point is mixing this stick with modules of different speed, latency or rank, which can prevent the system from posting or force it to run at the lowest common denominator. Using identical OWC modules across all slots avoids that issue.

2Rx8 dual-rank organisation

The decisive spec is the 2Rx8 dual-rank layout. The Precision 7760 memory controller expects this organisation for full-channel bandwidth; single-rank or quad-rank alternatives will either halve throughput or fail to train. Buyers who need a different rank configuration or ECC support cannot use this part.

Questions about this item

How can I verify the module is running at 3200 MHz with CL22 after installing it in my Dell Precision 7760?

Open Task Manager or a tool like CPU-Z and confirm the memory tab shows 3200 MT/s and CAS latency 22 at 1.2 V.

What comes in the package and is anything else required for installation?

The box contains one 16 GB 260-pin DDR4 SODIMM; no extra parts or tools are needed for the laptop slot.

Should I choose the 16 GB 3200 CL22 version or a different capacity for the Precision 7760?

This 16 GB 3200 CL22 module matches the system spec; add a second identical stick if you want dual-channel 32 GB.
