So I purchased a 4GB kit (2x2) and have just installed it on my 32-bit Vista OS.
Here is where I'm at. I've edited this post a couple times, so that my troubleshooting is as current as possible.
I've checked my System Preferences and my ram only reads 2750 MB. In my BIOS, it is only reading approx. 2800. The BIOS tells me that this RAM is represented with Video Memory included. So my current thought is that my nvidia graphics card is eating up 1.2 GB of RAM on me. That is my only explanation for my BIOS reading less than what is physically there.
I have individually checked both 2GB sticks and they both individually read in the BIOS at 2048 MB, so I know my full 4096 MB of RAM is accessible.
I have force enabled PEA/PAE, whatever its called using the elevated command prompt. No luck.
Any suggestions would be greatly appreciated. Right now I am looking into the specs on my graphics card and hoping to see 1.2 GB of RAM as a Device Requirement, at least that would be an explanation.
