Windows 7: RAM not Usable

RAM not Usable

I recently purchased a new HP Laptop G62. It is running windows 7 64bit. It came with 3gb ram installed, AMD dual channel phenom processor, everything was working fine. I purchased a 4gb ram upgrade. Windows recognizes the ram but still says only 1.74 usable. I went into BIOS and it recognizes 6gb. task manager only says 2810 total. If the 4gb is in slot #1 it will not even boot the computer whether there is anything in the second slot or not. I've went into msconfig and tried changing the maximum memory option to checked, unchecked, etc. I downloaded CPUID and here is what it shows
here is another pic showing it runs dual channel when the 2gb and 1gb ram is installed.RAM not Usable-mem2.jpg

the label on the 4gb ram is as follows (Patriot 4gb PC3-10600 SoDimm CL9)
the label on the 2gb ram is (Kingston 2gb 2Rx8 PC3-10600S)

My Bios does not offer a remap option either. Any thoughts would be greatly appreciated!

Does the board support a 4gb stick of ram ? it may be able to run 6gb total 3x2gb sticks

There are many HP G62 models. It looks like some of them use DDR2, others DDR3. Which one do you have?

There are only two slots, HP website says it is capable of supporting any amount of ram as long as its running windows 7 64bit.

You will have better luck with matched memory sticks of the same MFG, size, & speed.

It came with two different MFG, The replacement is the same speed. But why won't it even turn on with Just the 4gb installed. Aside from buying another memory stick and trying it, how do i determine if the 4gb stick i have now is possibly bad?

Test it by making a boot disk with Memtest86 on it.

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...
