RAM 4GB, only 2,94 usable

[tokinhornr]

Hi everyone, first of all sorry for my english, it's not my native language.
I have a HP Probook 4530s, Core i3, 4 GB RAM, using Windows Professional 64 bits. I've noticed that when I enter to (Panel Control) 'System' my RAM is only 2,94 GB usable from 4 GB. I enter into Virtual Memory Configuration and I found this:

I think you can understand without reading Spanish

I searched in the forum, and of course, Google, but I'm not sure about the solution. I'm afraid to make a mistake changing the Maximum Size to 4521 MB that is the 'recommended'.

Hope you understand me.
Thank you.

Reason why it is 2.94 Gb usable some Hardware might be using it to help it work better when doing demanding task such as intergrated Gpu

The ram is placed to make sure the system won't hang you in those area's the 4 gb's are there but some of your hardware needs it to keep up with everything else

I see... I get into Resource Monitor, and in Hardware Reserved appears 1082 MB. That's not a lot of memory reserved?
So, I don't have to change anything

One of two things:

1. Your graphics card is ussing 1 GB of address space, but not physical RAM
2. Your graphics card is using 1GB of physical RAM instead of having its own

The first is more likely. I'd be pretty surprised if your computer BIOS didn't have a memory remap feature in the BIOS so you could actually use all 4GB. In that case, your computer needs address space, but not physical RAM, to communicate with your graphics card. If that address space is located below 4 GB, it is 1GB of RAM that gets wasted. Memory remapping allocates the 1 GB of address space the graphics card needs above 4GB, so the full 4GB of address space for your system and programs can be mapped to the 4GB of physical RAM.

So boot to your BIOS and see if there is memory remapping (or sometimes called a hole) option to enable.

Yes, I've looked into my Intel's options, and I found that is usin 1.3 GB. Well, I'm gonna see what can I do.
Thank you very much.
