The maximum ram a 32 bit system will see is 3.5 mg.

Can only have more than 3GB of RAM running a 64bit system with 64bit OS. There is nothing you can do about other than upgrading to a 64but system.

Yeah, I just got my new computer Friday and it has 4gb, but it shows 3.25. It just what the system will recognize.

I experimented with 3G vs 2G. Everything is better with 2. I had to use a couple of 256 strips to take my unit up to 3G. I can not be sure and this is only my opinion but I think using the 256 strips to take it up to 3G was a mistake.
I think 2G is plenty. Two I Gig strips.
Seems to be biased towards the lowest gig card

Scott,
You are right, most motherboards will run all memory at the slowest speed of the differant RAM sticks installed. If you have 2 1Gb DDR2 sticks running at 667 Mhz and your 256 sticks running at say 400 Mhz. All your memory will run at 400 Mhz. In some cases you might even have a 2 Gb stick running at 667 and a couple of 1 Gb sticks running at 1066 Mhz. In this case the memory would run at the 667 Mhz speed.
32 Bit windows will only recognize about 3.6 Gb RAM (experts say anywhere from 3.2 to 3.8) In all cases any amount of RAM over this will not be used and in some cases RAM over that number will actually slow down what memory you do have available.
In my opinion the extra time and headaches necessary to make windows run well with 3+ Gb is not worth it. Most games will run their fastest with 2 Gb RAM. If you do have 64bit Windows then by all means you may get some benefit from the extra memory, but remember most games are written for 32 bit Windows and thus are really only running as a 32 bit App in a 64 bit OS.

32bit systems use the amount of RAM that totals to 4gb, including your video cards RAM, ie, with a 512mb video card, a 32bit OS will only be able to use 3.5gb of system memory

Tom nailed it. However much RAM is installed in your video card gets "pasted" at the end of 4GB for addressing purposes with a 32-bit OS. Those memory addresses are therefore not available to the CPU. The more RAM on your video card, the less RAM is recognized by Windows.
I have Vista 64 with 8 GB of RAM. 32-bit apps are only going to be able to use 4GB of that which means there's 4 GB free for use by Vista "housekeeping" services. It's actually running very nice so far using the default missions in FSX and graphics settings on high. I haven't fired up the DVA ships yet on this new computer, but plan to do so later today.

Often computers that come already built will have the default video card which drains some RAM. If you get an aftermarket video card that rund off its own processing power then you computer will be able to use all processor power for the computer alone and the video card can be self contained.

The CPU still needs to access the video RAM whether it's integrated into the mother board or on an add-on card so even add-on cards have to reserve blocks of mainboard addresses for their own use. Video RAM addresses are not available to Windows for general purpose use. The CPU/GPU issue is a different discussion altogether.

Started building pc's on May but I never installed more than 2GB on a motherboard that was why this question popped up. why did you had to look at each of my question and comment on them when there are a lot of question here.

Michael Long story short 4Gb in a 32 bit OS like XP or vista32 is OK to do, It is the way the system is designed in short, It will only see 3.25 of available ram for its use, There are a lot of debates on this, which are to long to discuss, But rest assured you other programs are using that extra .75 of ram that are in there. So dont feel threatened on these questions, perfectly normal to ask them.
