Capacity & Fit

This single 64 GB DDR4 SODIMM module delivers a large memory upgrade in one 260-pin stick. It targets laptops and compact systems that have a single slot available or need maximum density per slot. Buyers whose platforms require ECC or registered memory cannot use this unbuffered non-ECC design.

Thermals & Power

Operating at 1.35 V, the module draws modest power and generates little heat during typical workloads. Standard JEDEC voltage keeps thermal output low enough for passive cooling inside thin chassis. No active cooling or extra airflow is required beyond what the host system already provides.

Build Integration

The stick installs in any DDR4 SODIMM socket wired for 3200 MT/s operation at CL16 16-18-18 timings. A 64-bit operating system is needed to address the full capacity. Mixing with slower modules will force the entire memory subsystem to run at the lowest common speed.

Questions about this item

How do I install this 260-pin SODIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips click, then verify the system detects the full 64GB in BIOS.

What maintenance or replacement will this unbuffered DDR4 module need later?

No routine maintenance is required; if errors appear, run a memory test and replace the module under the manufacturer's lifetime warranty against defects.

What limit appears first under sustained heavy workloads with this CL16 1.35V kit?

The CAS latency of 16 and 1.35V voltage set the timing and thermal envelope that govern sustained throughput.
