Capacity & Compatibility

This A-Tech module provides 4GB of DDR3 laptop memory in a single 204-pin SO-DIMM. It runs at 1600MHz (PC3-12800) with CL11 latency and standard 1.5V operation. The unbuffered, non-ECC design targets notebook and all-in-one owners who need a straightforward capacity increase for everyday multitasking.

Installation Requirements

The stick fits any DDR3 SO-DIMM slot keyed for 204-pin modules and draws power at the JEDEC 1.5V level, so no voltage adjustment is required. Because it is unbuffered and non-ECC, the host platform must support standard consumer SO-DIMMs; systems that require registered or error-correcting memory will not accept this module.

Sustained Operation

Major-brand DRAM chips and full quality-assurance testing aim to deliver stable throughput during extended workloads such as large file transfers or prolonged browser sessions. The CL11 timing and 1.5V supply keep thermal output consistent, allowing the module to maintain its rated 1600MHz speed without throttling under continuous use.

Questions about this item

What CAS latency will I see when this DDR3 1600 module runs at full speed?

The module is rated CL11, so the memory controller will use an 11-cycle delay at 1600 MHz.

How much heat and power should I expect from a 1.5 V DDR3 SODIMM during continuous use?

At the standard 1.5 V DDR3 voltage the stick draws only a few watts and stays cool enough for passive laptop cooling.

My laptop uses 204-pin DDR3 slots — will this stick fit and work without extra parts?

Yes, the 204-pin SO-DIMM form factor matches the slot and the module is unbuffered non-ECC, so it installs directly.
