OK, so I went ahead and bit the bullet and installed 8G ram additional, so my specs are as follows:
Windows 7 Professional, 32-bit
12 G total RAM installed 4 original + 8 new (all 4 slots now filled)
The computer is recognizing the RAM and tells me 12 G installed, but unfortunately it says 9g being used as "Hardware Reserved" on the resource monitor. I googled this, and I updated my bios, I made sure that the maximum memory box was unchecked on msconfig, as several online threads suggested, but does not seem to change..... I'm afraid that I will not get any added performance, since I'm still stuck using only about 3G of "usable memory"....
Any thoughts on this? Is it possible that my computer might simply re-allocate this memory if it needs it for applications and processes??
Thanks
