4GB DDR3 SODIMM for notebooks

This single 4GB module uses 204-pin DDR3 SO-DIMM form factor to upgrade laptop memory. It targets users who need a straightforward capacity increase for everyday multitasking on DDR3 platforms. The unbuffered, non-ECC design fits standard notebook slots without registered buffering. Buyers who want more storage or a different memory generation should look elsewhere.

DDR3 1600MHz CL11 interface limits

The module runs at 1600MHz with PC3-12800 rating and CL11 latency at 1.5V. DDR3 architecture caps bandwidth at this specification, so systems already at the platform maximum will not gain further throughput from this stick. Mixing with faster or slower DDR3 modules forces the whole array to the lowest common speed. Buyers who need higher bandwidth than DDR3 provides cannot meet that need with this product.

Check DDR3 slot voltage and pin count

Verify your notebook accepts 204-pin DDR3 SO-DIMM modules at 1.5V before ordering. Some ultra-thin or older designs use different pin counts or lower voltages that are physically or electrically incompatible. The single-rank 1RX8 organisation works with most consumer chipsets, but certain OEM BIOSes restrict detectable densities. Buyers who need ECC or registered memory cannot use this unbuffered module.

Questions about this item

Is the single 4 GB module the only capacity option for this RSO12800S8C4 kit?

Yes, this part number is a single 4 GB SODIMM. If you need 8 GB you would buy two of these modules and run them in dual-channel mode.

What does the 1600 MHz rating actually deliver inside a laptop?

The module runs at 1600 MHz with CL11 timing, giving a peak transfer rate of PC3-12800. Your laptop’s memory controller will set the final speed, but the stick is rated for that bandwidth.

Will the 204-pin DDR3 SO-DIMM work in any laptop slot?

It fits any standard 204-pin DDR3 SO-DIMM socket. The module is unbuffered, non-ECC and runs at 1.5 V, which matches the electrical spec for most mainstream notebooks.
