Computer Memory Solutions CM4096642666SO 64GB (2x32GB) DDR4 2666MHz SODIMM memory upgrade

System-specific DDR4 upgrade

This 64 GB kit contains two 32 GB SO-DIMM modules built for Dell OptiPlex 7070 Ultra and Precision 5540 systems. It delivers the exact pin count and timing those platforms expect, so the memory is recognised immediately on installation. The unbuffered, non-ECC design matches the factory specification for these workstations and compact desktops. Buyers who need a different capacity or a different form factor should look elsewhere.

Low-voltage operation

Each module runs at 1.2 V with CL19 timings, keeping power draw and heat output minimal inside the tight chassis of the supported Dell models. No heat spreader is fitted, allowing the sticks to sit flush in the two SODIMM sockets without clearance issues. The memory operates silently because it has no moving parts and requires no active cooling. Systems that demand registered or ECC memory cannot use this kit.

64 GB matched pair

The two 32 GB modules are tested together as a matched pair to ensure stable dual-channel performance at 2666 MHz (PC4-21300). This capacity is the maximum the listed Dell platforms officially support, so no larger configuration is possible. A 64-bit operating system is required to address the full amount. Builders who need more than 64 GB or a different speed grade will not be served by this product.
