Speed DDR3 1066 (PC3 8500)

CAS Latency CL7

  • 4GB capacity lets you run more apps at once with a single 204-pin DDR3 SODIMM module
  • 1066 MHz DDR3 speed (PC3-8500) reduces load times for everyday tasks
  • CL7 CAS latency at 1.5V delivers responsive performance for compatible laptops
  • Non-ECC unbuffered design ensures broad compatibility with major-brand notebooks and all-in-ones
  • Rigorously tested with major-brand chips for dependable operation in DDR3 systems

Capacity and Compatibility

This 4GB DDR3 SODIMM module operates at 1066MHz with a CAS latency of CL7 and runs at 1.5V. It uses a 204-pin form factor designed for laptops, notebooks and all-in-one PCs that accept DDR3 memory. The non-ECC, unbuffered design suits standard consumer systems.

Build Integration

Installation requires an available DDR3 SODIMM slot and a platform that supports 1.5V DDR3 modules at the PC3-8500 speed grade. The module uses major-brand chips and contains no heat spreader, keeping the profile low for tight chassis. It frees a second slot for future expansion if the system supports more than 4GB.

Sustained Operation

Quality assurance testing validates stability under continuous workloads rather than brief bursts. The CL7 timing and standard voltage help maintain consistent throughput during extended multitasking or background tasks. The lifetime warranty reflects the manufacturer’s confidence in long-term reliability.

Questions about this item

What voltage does the 1.5 V DDR3 SODIMM draw under continuous load?

The module is rated at 1.5 V and maintains that voltage during sustained operation.

How much heat does the 204-pin DDR3 module produce when running all day?

Without a heat spreader the stick relies on normal case airflow; it runs at standard DDR3 thermals for 1.5 V CL7 parts.

What must the laptop already have to accept this 4 GB DDR3 1066 MHz stick?

A free 204-pin DDR3 SODIMM slot that supports 1.5 V non-ECC unbuffered memory at PC3-8500 speed.
