64GB DDR4 3200 SODIMM kit

This kit delivers 64GB of DDR4 memory across four 16GB SODIMM modules rated at 3200MHz. It targets laptop and compact desktop owners who need maximum capacity for multitasking, virtual machines or large datasets. A 64-bit operating system is required to address the full amount.

Unbuffered non-ECC 260-pin modules

Each stick runs at 1.35V with CL16 16-18-18 timings in a 2Rx8 configuration using major brand chipsets. The standard 260-pin SODIMM form factor fits compatible slots directly, while the unbuffered non-ECC design suits consumer platforms. Mixing with other modules will force all memory to run at the slowest installed speed.

Upgrade from lower-capacity or slower DDR4

Replacing smaller or slower DDR4 SODIMMs with this matched quad-channel kit removes capacity bottlenecks and raises the memory ceiling to 64GB. The jump is worthwhile when workloads exceed 32GB or when the system currently runs below 3200MHz. Buyers whose platforms limit total memory below 64GB or require ECC registered DIMMs cannot use this kit.

Questions about this item

What does the DDR4 3200 (PC4 25600) interface cap in practice?

The kit runs at 3200 MHz with CL16 timing and 1.35 V. All installed modules will operate at the slowest speed present in the system or allowed by the processor.

What physical slot and pin count does this SODIMM need?

Each 16 GB module uses the 260-pin SODIMM form factor and requires a standard DDR4 SODIMM slot in the laptop or small-form-factor board.

How are the four modules installed and what step is often missed?

Insert each stick at an angle until the contacts seat, then press down until the side clips click. For best performance, populate matched pairs in the correct channels; a 64-bit OS is needed to address the full 64 GB.
