I purchased my Turbo Memory module off www.pricegrabber.com
from one of their sellers. It was only about $35.00 shipped. I had to do a search by the part number to locate it. Here's the link. I bought it from NextWareHouse.com and it showed up pretty quickly.http://computers.pricegrabber.com/la...VCPEMWR001G110
I'm running 2 GB of RAM right now. It probably made some difference, though it hasn't been really noticeable. Aside from adding the Turbo Memory I've done my own OS tweaks from researching. That probably helped the efficiency more than anything. I use TweakVI from www.totalidea.com
, X-Setup Pro, and Tweak UAC. The other thing I did was pay a visit to Black Viper's web site and change up my services that I did not need running in the background.
I pretty satisfied with the performance of my 1520 now. Since I have a little change burning a hole in my pocket, I might put some extra RAM to make 4 GB total. It will probably won't make a huge difference, but RAM has dropped in price to make it fairly afforable.
