Forgot to add that I've put the new RAM back in. It was impossible to do anything as simple as staring up Iexplorer without it. So the problem is worse when I use the original system configuration. Eeek!
Hi all! I'm using a Dell Dimension 8100 which originally came with 256mb of non-ECC RDRAM. I've been running XP for years with no problems, and decided to double my RAM to speed it up a little recently. I installed 2 sticks of 128mb ECC RDRAM in the 'top' two slots (the bottom two were filled with the original RAM) and the computer seemed to love it... at first! In the course of three days I saw a serious downturn in performance, and I'm curious as to why.
The second time I started the computer after the install, it lagged seriously in the XP screen with the scroll bar to indicate the loading of the OS. Once that got started though, no problems.
Starting yesterday, once the system did load and Windows started, it took a while to be able to access files at first. I tried altering startup settings with MSCONFIG, no dice. Ran spyware, adware, and virus programs, also no change in performance.
Today, the problem was so bad that I couldn't open a simple picture file without the computer completely bogging down. Even moving the mouse resulted in jerky cursor movements. I tried removing the new RAM and running it with the original settings, but no change. Trying to access large files/load webpages has resulted in a system freeze several times. On the upside, the Windows loading screen no longer lags, heh.
Looking at my CPU usage shows me that the system is going at nearly 100% whenever I'm opening a file or loading a webpage. During these operations, I get the same jerky cursor movement and slow performance, but once things load, the CPU usage drops down to nearly nothing and all's well. Every time I click on something, it gives me three mouse click sounds. Anything that seems to take any processing power shoots the system up to 100% again. I honestly have no idea what's going on, and would greatly appreciate some advice. Is it the mixing of non-ECC and ECC RAM? If so, why wouldn't removing the new RAM fix the problem?
