I installed the new RAM, and rebooted after checking to be sure the system recognized 3.25GB (it did).
After waiting for a few minutes after the reboot, I loaded the performance monitor again and noticed that my computer now uses 740-790 megabytes of RAM, in the EXACT SAME configuration as before I switched out the RAM.
Why would my computer start using MORE RAM when all I did was upgrade the modules from 2GB to 4GB? Doesn't seem logical.
ALSO - just refreshed my Windows Experience Score and the one for memory dropped from 4.9 to 4.5. I thought this score would increase when I doubled my RAM. What gives? Did I just waste money? It sounds like it would be better to go back to 2GB.
Windows will adjust the allocation of system memory automatically based on the amount of ram installed. So it would make sense that the increaded memory nstalled = increased memory allocation for system resources.
To address the second question what was the CAS timing and speed of the memory before and after the upgrade ?
I would run CPUZ and see what your memory timings were /are
it should have improved your score BTW.
Verify your running in Dual Channel operation
If your using two different memory speeds your system will down clock to the slowest memory as well.
