System-specific DDR5 SODIMM kit

This 64 GB kit contains two 32 GB DDR5 5200 modules built for the Dell Precision 7680 mobile workstation. It targets IT professionals and power users who need maximum supported memory in that specific chassis.

Unbuffered non-ECC layout with 2Rx8 organisation

The dual-rank 2Rx8 design fills both SODIMM slots at once, delivering the full 64 GB capacity the platform allows. CL38 timing at 1.1 V operates within the workstation's validated JEDEC profile, so no manual tuning or XMP profiles are required.

262-pin form factor with major-OEM DRAM chips

Modules use Samsung, Micron or Hynix components and lack a heat spreader to fit the tight Precision 7680 socket clearance. The standard 262-pin DDR5 SODIMM edge connector ensures direct compatibility with the laptop's memory slots.

Questions about this item

Will the 2Rx8 SODIMM modules need any firmware updates or re-seating after the Dell Precision 7680 runs for several months?

No firmware is required for these modules. Standard installation seats them in the 262-pin slots; re-seating is only needed if the system is moved while powered on.

What limits sustained throughput first — the CL38 latency or the 5200 MT/s data rate?

The 5200 MT/s data rate sets the peak bandwidth ceiling; CL38 latency affects access time but does not cap sustained transfer speed.

How much heat and power will the 1.1 V kit add when the workstation runs all day?

Each 32 GB module draws 1.1 V at the rated speed; total kit power is low for DDR5 SODIMMs and requires no extra cooling beyond the laptop's existing airflow.
