starting with mfg name, series and model number....like 'HP Pavilion e1406a'.
From there we can talk specifics and specific combinations.
I have a new Windows 7 64 bit, i5 2400, integrated graphics system that I ordered with only 2GB of RAM (to add 2GB more at time of purchase added $60). The system is used for work. Ususal Internet, word processing, Quickbooks, Photoshop Elements, Coreldraw, Vectormagic, "lite" video conversion are programs I commonly use, though not all at the same time. When I have three browsers open (three + tabs each), antivirus running, Word, UPS Worldship, opening a 600dpi scan in PSE, Task Manager shows around 1.7GB memory usage...and it feels s..l...o...w. Booting and shutting down Windows takes 3 times longer than my old XP P4 1GB system at home.
I have 2x1GB installed and one pair of RAM slots empty. I can either add 2x2GB, giving me 6GB total, or add 2x4GB for a total of 10GB. It would be nice to do this once and get it over with as I plan on keeping this a while and everyone I talk to says RAM is so cheap right now (you can see I'm leaning towards the 2x4GB upgrade).
I know 10GB is way more than I need, but seems like a better deal than pulling the 2x1GB OEM sticks and adding another 2x2GB for 8GB.
I am confused and looking for a clearcut idea of if I'll need more than 6GB of RAM. Given what I'm doing, how much faster will 8 or 10GB be over 6GB? Noticeable? Does the speed hit a plateau with a certain amount or does each GB incrementally speed everything up?
