I bought a $200 refurbished Dell laptop for my 10 yr old daughter as her only Christmas present last year. It worked fine for surfing the Internet and the basic applications a 10 year old would use.
I returned to college this fall and have been using her laptop to submit homework as mine had died a few years ago. I suddenly became very frustrated with how slow it took to do anything. It came with 4Gb of RAM and after I upgraded to the two 8gb cards, I noticed a considerable difference in improved performance!
I previously worked with AutoCAD in my career field and had a $3300 company laptop to design parts with. I realized very quickly how spoiled I had become when it took my daughter's laptop almost 90 minutes to install Microsoft Office 365 (before increasing RAM)!
Before installing the new RAM, the task manager would show the amount of memory used at 99%. After installing the new RAM, the memory in use is usually around 20-40% and the processor now gets shown at 99% when I'm doing more than a few things at once.
I noticed improvements in how fast programs opened up and were actually ready to use instead of waiting for the program to finish loading before your able to click on anything.
The improvement in RAM was considerably noticeable, but since the processor was also slower, it wasn't the amount of improvement I was hoping for. (I did convince the Mrs to let me buy a new laptop for school as a result... Hello INTEL XEON!)
Depending on the specs of your current RAM and processor, you may have better results than I did after upgrading your RAM.
I am happy with my purchase. For the price, I figured it was worth the investment. Even if it wasn't the performance improvement I was looking for, I knew it was an improvement my daughter could benefit from.
Overall, in my personal opinion, I believe the RAM was priced reasonably and it did improve the performance of my laptop.
Based on my previous work computer, I had unrealistic expectations on how much improved performance I was going receive. My daughter's $200 refurbished laptop isn't going to perform the same as a laptop designed to run AutoCAD.
I would recommend these, but I am very impatient. If you can wait to have them delivered, they are priced differently on other retailer websites. I couldn't wait and bought mine in store.
Assuming you are increasing your RAM by at least 4Gb, you should be able to see a difference in your computer performance.
