    I may not have elaborated enough with my question.

    I had 1gig of memory consisting of two 512gigs of ram in two slots. I purchased another 1 gig of ram installed it.
    However after installation it was only showing the 1.5gigs, and showing one slot empty. am I led to believe that this will not show up on the amount of memory I have at my disposal.
    I have attached a copy my memory results if it is of any help.

The most likely reason is the memory you have isnt compatible with eachother. If the types of ram are too different they often wont work together. If you google and download a program called cpu-z it will tell you what ram you have in each slot and you can see how different they are.

That's all that it will show until you add more. you can not count the ram on any video card.

    If you moved a 512mb stick to another slot and put the 1024mb stick in its place, you may have a dead slot. At boot up, go into bios to see what it does. I like the free download "cpuz". It can tell you a lot. how many slots and what is in each one.

    If this is an older board and you have pc133 memory. It may only read 1.5gb of ram and allocate the rest to the system. I am running an asus p5ld2 that has a max of 4gb on 4 slots. I ran 4x 1024mb of pc2 667 but at boot up it only showed 3.5 because the rest was allocated to the system so i cut off 2gb of ram. it see and uses only the 2gb. my system runs faster with just 2gb as well. you can get you system to see more but you need to have a board that has m.t.r.r. and know how to config it.

I upgraded to 1 gig ddr2 800mhz pc6400 dimm ram but it only shows up as 512 mb. why ?

The P5VDC2-MX motherboard specs state that DDR2 533/400 ram is supported. Your 800 is just too fast and is forced to operate at a slow speed. It is not unusual to get half the amount of memory shown when operating at half speed.

Cpu speed for ddr 400 ram

cpu speed has nothing to do with ram. they are completely independant. ram speed is important to the FSB (front serial bus) this is the speed at which your motherboard communicates with the devives attached to it. cpu speed refers to how fast a cpu can process info. or how fast it "thinks". most motherboards have the capability of upgrading cpu's. your mobo (motherboard will support the following cpu's:
any pentium 4 up to 3.0 ghz
it supports the following ram
ddr (nott ddr 2 or 3) up to 2 gigs (1 gig each slot) of 533mhz speed (or less)
it also supports up to 2 gigs of sdram either pc133 or pc100
you are using 400 speed ram as you stated i would upgrade to a 533 speed ram as it will be faster, but this is not necessary. as for the cpu just get any P4 (pentium 4) that is 3.0 ghz or less and it will work.

Upgrading my Satellite l45-s7423 for gaming

A. vista 32bit supports 2.5-3 gigs and vista 64bit supports 8-16. i would stick at least 2gigs for vista 3gigs being recommended. a way to figure out what type of ram is to download CPU-Z.

B.most likely you can't upgrade your graphics card. but i would check Toshiba's web site to see for sure.

C. there are things that you can try to make it slightly better for gaming. try downloading the latest video drivers for it.

a lot of laptops have the option of dedicating some system ram for video. try turning that up.

the next thing you could do is download riva tuner. this will let you overclock your gpu but don't overclock too much cause you could fry the video card and you might not be able to replace it.

Ram upgrade

It's generally not a good idea to mix sizes as your more likely to get problems, but that said it probably should still work it's most likely your configuration consult your motherboard book as to what order you should install the memory you have.
