Compatible Dell Precision 7760 Upgrade

This 32GB DDR4 SODIMM is built specifically for the Dell Precision 7760 mobile workstation. It delivers a JEDEC-compliant 3200MHz speed at CL22 latency and 1.2V operation. The unbuffered, non-ECC module targets professionals who need a reliable capacity increase for demanding workflows without altering factory voltage settings.

260-Pin DDR4 Slot Integration

The 2Rx8 dual-rank stick occupies a single 260-pin SO-DIMM socket inside the chassis. It requires no heat spreader, preserving clearance in tight laptop bays and leaving adjacent slots free for matched pairs. Installation follows standard DIY steps and the module is tested to meet OEM specifications for immediate recognition by the system BIOS.

Sustained Multitasking Stability

Under continuous load the module maintains its rated 3200MHz throughput at the standard 1.2V, avoiding the voltage spikes that can throttle mobile CPUs. The 100% JEDEC compliance and ROHS certification ensure consistent timing across extended render, compile or virtualisation sessions. Mixed-capacity configurations are not recommended for optimal sustained bandwidth.

Questions about this item

How does the CL22 latency affect sustained workloads on the Dell Precision 7760?

CL22 is the CAS latency timing for this 3200 MHz DDR4 module. It determines the delay before data is available after a request, which is the primary timing limit during continuous memory-intensive tasks.

What heat output should I expect from this 1.2 V DDR4 SODIMM during all-day operation?

This module runs at the standard 1.2 V DDR4 voltage and has no heat spreader. Under sustained load it will generate typical low-power DDR4 heat, well within the Dell Precision 7760's cooling design.

Does my Dell Precision 7760 need a specific BIOS version or matched DIMMs for this 2Rx8 module to work?

The module is tested for the Precision 7760 and follows JEDEC DDR4 3200 specifications. OWC recommends using identical capacity, speed and manufacturer DIMMs for optimal performance.
