Windows 7: Usable RAM optimization?

OK - I will try this tonight. You can see in the attached img that the OS is 64 bit, however I'm not certain this means that Win 7 Home automatically utilizes it. On MS, it seems to indicate that.

OK - I sequentially removed the memory. Each time, same result: 4GB RAM, 2.96Gb usable. By the RAM usage meter, both showed 50% RAM usage at fresh boot/idle.

When I plugged the 2nd RAM back in, it says 8GB RAM, 2.96 GB usable again... now the guage hovers around 60% RAM usage.

Thoughts?

I feel for ya.
One person gave this solution:
1)Run
2)type "msconfig"
3)Go under the "boot" tab
4)click "advanced options" button
5)UNCHECK! "Maximum memory"
6)Reboot

Another user suggested "memory remapping" in the bios

Many people, including myself, don't have this problem. But several do as well, and the answers seem to vary.

Thinking back, the last person I helped with this much RAM being hardware reserved (this is where the non-usuable RAM goes), had ticked the maximum memory box and left the number as 0. Neither box should be checked. Despite common claims, it does not boost performance to check either.

That did the trick... unchecking Max memory. Now it doesn't say 2.96GB available. I've attached a screen shot of the power meter, showing 5.9GB avail. Any suggested tweaks I should do to further enhance this?

Also, In the misconfig, I noticed that "1 processor" on boot is checked. Since I have 2, would it help to activate the 2nd? See screenshot.

No it will not help to change processor setting. Windows will load both cores by default. That is for developers that want to test how there apps will run under different environments. Leave it unchecked.

As I stated before, you should not check either. Both are used all the time. And, unlike housry said (sorry), it is meant for debugging purposes.

Actually we are both right! It is used for both debugging and for programmers to test their code in single core mode if they are running multi core system.

Quote:
If you have a multiple core CPU (Ex: Intel Core Duo or Quad CPU) or multiple CPUs, then this will show you how to change the Number of Processors that will be used during boot up for troubleshooting and debugging purposes to be able to determine if there is a problem with a single processor/core, or for a programmer to test their code against a single core while running on their multi-core system.
