Great service by PB tech explained what RAM I needed and it was easy to install . This product sped up my laptop for sure Thanks PB Tech team

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.

This Memory is working great in my old MacBook and the performance difference is huge I would highly recommend this product and PB techs delivery is always hassle free and quick.

i have purchased quiet a few thing from pb tech and found all to be good and starf alway helpful so thank you to all that work at pb tech

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

I was having performance issues with my Mac so I called Apple. They suggested adding more memory so I went to Micro Center to get the part. I'm not technical so I asked the Apple guy at Micro Center if he could give me a few tips and he was very helpful.

Upgraded from 4gb to 8gb. This one is different from the stick of ram that was already in my laptop, but they seem to work just fine together.

It works with my Lenovo E540

I own an Asus K55n-DB81 with 6GB of RAM, A8-4500M processor, HD 7640G graphics. I bought this as an upgrade to boost the RAM to 8GB. I play Elder Scrolls Online as well as World of Warcraft with my laptop and wanted to boost the graphics on the games.

Works just fine in my TS140, no issues or special configuration was required and it gets along fine with the 4GB stick that the server shipped with. I just threw it in, let memtest run to confirm it was good and that was it.

Replaced failing memory sticks in current desktop computer and was very pleased that the computer runs without issues. This restored a computer that had a blue screen of death...
