Did exactly what I wanted - sped up the old laptop significantly.

I bought this a few months back to upgrade the memory on my new laptop. The laptop came with one 4GB module and one 2GB module--I don't know why they do that. Anyway, the installation was painless and the memory passes Memtest86 with no errors. I have yet to have an issue with Crucial memory.

Upgraded a Dell t3500 from 4 to 12 G... no fuss. Works well.

I purchased 2 X 4 GB of this memory to up grade our Qnap TS-251 as it was struggling with the installed 4 GB. I replaced both Sodimms to maintain the same memory as prescribed by Qnap. As result the Qnap preforms a lot better, not so much Swap file use - which was causing a lot of Disk activity, it also appeared to reduce the CPU load. Great result.
