8GB DDR4 SODIMM for Dell Precision

This 8GB DDR4 3200MHz SODIMM module is built for Dell Precision 7550, 7560, 7730, 7740 and 7750 workstations. It uses a 260-pin unbuffered non-ECC design with CL22 latency and 1.2V operation. The memory meets JEDEC PC4-25600 specifications and is tested for warranty-safe upgrades.

Suits single-slot upgrades.

Professionals expanding a supported Precision laptop with one extra module will benefit from the straightforward compatibility. Buyers who require error-correcting code memory or registered DIMMs for server-grade stability should look elsewhere. Systems needing higher total capacity than a single 8GB stick provides will need additional compatible modules.

Fits 260-pin DDR4 slots; frees multitasking headroom

The module installs directly into the laptop's DDR4 SODIMM socket without tools or heat spreader clearance concerns. Adding this memory allows the system to keep more applications and larger files in active RAM, reducing swap-file reliance. Matching capacity, speed and manufacturer across all populated slots is recommended for optimal stability.

Questions about this item

Will this 260-pin SODIMM fit the memory slots in my Dell Precision 7550?

Yes, the module is built to the 260-pin DDR4 SODIMM form factor used by the Precision 7550, 7560, 7730, 7740 and 7750.

Can I add this CL22 3200 MHz stick alongside the original CL22 memory already in my Precision 7740?

Mixing modules with the same 3200 MHz speed and CL22 latency works, but OWC recommends matching capacity, speed and manufacturer for optimal performance.

How can I confirm the new 8 GB module is running at 3200 MHz after installation?

Open Task Manager or a system information tool and verify the memory speed reads 3200 MHz (PC4-25600) with the correct 8 GB capacity detected.
