Computer Memory Solutions 64GB (2x32GB) DDR4 3200MHz CL16 SODIMM D117 memory upgrade

SKU CH-ZJS2-MKKTK

A 64 GB kit of two 32 GB DDR4 SODIMM modules running at 3200 MHz with CL16 latency for Dell Precision mobile workstations

  • Total capacity64 GB (2 × 32 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor Brand Chipset
  • CAS latencyCL16
  • Memory timings16-18-18
  • Rated voltage1.35 V
  • 64GB dual-channel kit doubles workstation memory capacity
  • 3200MHz CL16 timing accelerates data-intensive workflows
  • 35V DDR4 modules reduce power draw under load
  • Validated for Dell Precision 5560, 7550 and 7750
  • 260-pin SODIMM form factor fits mobile workstation slots

Compatible Dell Precision Workstations

This 64GB kit targets Dell and Alienware Precision Mobile Workstation 5560, 7550 and 7750 owners who need the full 128GB maximum capacity across four SODIMM sockets. Each module is built with major-brand chips and validated for those specific platforms.

64GB DDR4 3200 CL16 Headroom

Two 32GB 2Rx8 modules deliver 64GB at 3200MHz with CL16 timing and 1.35V operation, leaving two sockets free for a later upgrade to the 128GB limit. Mixed modules will run at the speed of the slowest installed part or the processor's memory controller ceiling.

DDR4 SODIMM Practical Limits

The 260-pin DDR4 SO-DIMM form factor fits only laptops and mobile workstations that accept this standard; desktop DIMM slots are physically incompatible. Non-ECC unbuffered operation suits the listed Precision models, while registered or ECC modules would not function in these systems.

Questions about this item

Will these 3200 MHz CL16 modules downclock to match the slower DDR4 SODIMMs already installed in my Precision 7550?

Yes, all memory in the system will run at the speed of the slowest installed modules or the processor limit.

How can I confirm the kit is running at 3200 MHz with CL16 timings after installation?

Check the memory speed and 16-18-18 timings in the BIOS or with a system-information tool such as CPU-Z.

Does the D117 kit include only the two 32 GB SODIMMs, or are tools and thermal pads also supplied?

The box contains the two 260-pin DDR4 SODIMMs only; no tools or thermal pads are included.
