Dimension 9200 memory speed
My 3 years old Dimension 9200 (E6700 1033MHz FSB) was delivered with 4*512 MB 667 MHz DDR2 RAM.
The Windows 7 Experience Index reports its lowest value for the memory (5.5). From what I understand, the Windows memory test evaluates the RAM perf, not amount ("memory operations per second").
As a first step to get the most of my system, I upgraded the 667MHz RAM to 2*1 GB 800 MHz DDR2 RAM (and recognized as such by the BIOS)
To my surprise, the Windows perf index is still reporting 5.5 for "memory operations per second"....did I waste several 10's of Euros ?
What is the memory ops per sec bottleneck on this system ?
Or is Windows 7 index not a good estimation of overall RAM performance ?

Personally, I don't pay attention to the Windows Experience Index. I go by feel and how my system is performing.
I have an XPS 410 / 9200 Dimension with 6GB of RAM (mixed Crucial - 4GB 800MHz, Crucial - 2GB 667MHz) running at 667MHz. My RAM index value shows 7.1. What does that mean? Heck if I know! Does it mean my RAM is better than yours or since I have 6GB -vs- your 2GB the index is higher for me? Heck if I know! Do I care? No. :) As long as my system performs well, it's all good.
By upgrading your RAM to 800MHz, you've topped out the speed. However, in my opinion, you won't see much performance improvement with 800MHz -vs- 667MHz. Did you waste your money? I don't think so. If I were you, I'd add some of your 2x512MB (667MHz) for a total of 3GB. Even though you'll be running at 667MHz speed you won't notice a difference in speed, but you may notice some improved application performance due to the extra GB of RAM.
