Work a treat. I increased the RAM to 8 GB with the result that my 10 year old laptop using Windows 10 is much quicker now.

Arrived quickly, fitted easily, worked beautifully.

Great memory boost to my iMac - I bought one last year too.

Extra kick of life into an old Samsung laptop

Fitted two x 4 GB Ram to my ageing All in One Acer. Have to say I am pleased with the improvement in performance. For a little investment and time I can keep it going a while longer! Also relatively easy to install and I am a serious amateur!
