I tried to use the scanner and it said it couldn't update my system. Why would that be when I hadn't done anything to it before...still only had the 2 1GB SODIMMs. However, using the advance tool search by model it said I could update. I already knew I could only go up to 4GB max.
I'm also confused by your post that RAM is RAM is RAM. If that was the case, then why weren't the two I bought compatible with each other? They both worked singly, just not when I put them both together. I'm just going to cross my fingers that the kit works and if so, count my blessings and realize I am not going to understand the logistics of it all. ;D
I have an emachines, E525, single processor, 64-bit, Win 7.
My computer was running extremely slow, and after a couple of tests, I saw I had excessive paging, so I needed to add RAM. My CPU and physical memory usage were at the very top when looking at the task manager. I had a friend help me clear up some background items, which lowered my physical memory usage to a little above the halfway point. He said I could go ahead and add RAM if I wanted since the computer was still going slow.
I went to crucial.com and entered the information instead of doing the scan (ironically, I did the scan later and it said it couldn't update my computer). I looked at the memory it listed as able to buy and wrote down all of the specs. I then went to Newegg and bought a 2GB. I took out one of the two 1GB sticks it originally came with and replaced it with the 2GB thinking I would then have 3GB. My computer wouldn't start and my friend suggested that it just wasn't compatible with the original RAM. So I took out both 1GB sticks and put in the Newegg 2GB. It worked! Problem is, I still only have 2GB and my computer is going slow.
So I bought another 2GB from Newegg, the exact same one, and added it to the second slot, for a total of 4GB. I turned on my computer and was excited to have everything running quickly. I stayed on my computer for a little bit (not exactly sure how long) and then went to bed. When I awoke, my screen was going back and forth sideways really fast, like it was being shaken. I turned it off, and when I came back from work at the end of the day, it was still doing it. I took out the newest 2GB and my computer was okay. I adjusted the paging back to auto (my friend had previously adjusted it) in the hopes that it would help, but I still can't add the second 2GB stick without my computer going all wonky.
Any ideas would be greatly appreciated! Thanks!
