  • 204-pin SODIMM form factor matches notebook sockets

Laptop DDR3 1600 Upgrade

This 4 GB SODIMM adds memory to laptops, notebooks and all-in-one PCs that use DDR3 SO-DIMM slots. It replaces Samsung M471B5273CH0-CK0, M471B5273DH0-CK0 and M471B5273EB0-CK0 modules. The single 4 GB stick suits users who have one free slot or who are replacing a failed module.

DDR3 1600 Speed Limit

The module runs at DDR3 1600 (PC3-12800) with CL11 latency at 1.50 V. DDR3 memory controllers cannot exceed this generation’s transfer rate, so the system will operate at the lowest speed among installed modules. Buyers who need higher bandwidth must choose a platform that supports a newer memory standard.

4 GB Single-Module Capacity

Capacity is fixed at 4 GB in one 204-pin unbuffered non-ECC module. Systems that require more total memory or that only accept higher-density sticks will not be satisfied by this part. Verify the maximum supported capacity per slot before ordering.

Questions about this item

Should I choose the 4GB module or look for a different capacity?

This listing is a single 4GB stick; if your laptop has two slots you can add a second matching module later, but the page only offers this one capacity.

What does the 1600MHz rating mean once the stick is installed?

The module runs at DDR3 1600 (PC3-12800) with CL11 timing at 1.5V; actual throughput depends on your laptop's memory controller and whether it supports that speed.

How does the 204-pin DDR3 SO-DIMM interface limit performance?

The 204-pin DDR3 SO-DIMM form factor caps you to DDR3 signalling and a maximum of PC3-12800 bandwidth on compatible AMD or Intel platforms.
