Windows 7: Only 3 Gb of usable ram

tw3kk is right. I am not used to the Windows 7 memory reporting yet - the same terms have different meaning between XP and Windows 7. From your screen-shot:

Installed Physical memory = just that
Total Physical memory = Installed - memory mapped devices (if no remapping)
Available Physical memory = Installed physical memory - memory in use

So your discrepancy is none at all - just the amount of memory that is in use.

I think you are using it. That "missing" memory is just memory that IS in use by you, as tw3kk rightly pointed out. So you ARE able to use all of your 8GB of RAM.

As was already said earlier, you get the best view from the colored bar in the Resource Monitor > Memory tab. All the other numbers, e.g. in task manager, are very confusing. Example:

The reason for this is with 32 bit encryption 4294967295 is the highest number it can hit.

The reason for this is in 32 bit 4294967295 is max number a computer can encrypt.

The max number for 64 bit encryption is 18446744073709551615.

Less than 4.0 GB RAM usable?
It's funny, because ALL of my RAM was usable some time ago. (I have no idea how long ago this was, but it was on the same OS) I am using Windows 7 Professional 32-bit. I know about the whole 32-bit issue where some say you can't use much more than 3GB. Well, I WAS. I wouldn't be writing this...

RAM 6.0 GB (1.95 GB Usable) WTF?!
What's this all about? Last time I checked system properties it said 5.5 GB usable. Now, today I noticed that my sidebar said that my memory is 40% in use and there's only 1.5 GB available. What's going on here? I was thinking it could be my video card taking the memory, but I didn't change any...
