HOW MUCH RAM WILL IT SUPPORT - Fujitsu Siemens AMILO Pro V2000 Notebook

Yes you can but the higher spec DDR2/800 RAM will run at at lower speed same as the DDR2/ 667 RAM.
When you install the DDR2/800 RAM and the BIOS only detects 1Gb of RAM then this RAM is not compatible with the 1st RAM module. In this case use RAM module that is the same make and speed as the original RAM module.

Max Supported Memory 4 GB Supported RAM Technology DDR SDRAM Supported RAM Speed 400 MHz, 333 MHz Supported RAM (Registered or Buffered) Unbuffered RAM Features Dual channel memory architecture

It looks like your computer is seeing only one 512Mb RAM module. Your computer uses shared RAM - 448Mb RAM is available for the computer and 64Mb is reserved for video RAM (448 + 64 = 512Mb) of RAM.
One of the RAM modules may be faulty. To determine which RAM module is faulty, remove both RAM modules and insert one RAM module at a time to determine the faulty RAM module.
If both RAM modules are OK then -
Some computers do not like mixed RAM modules from different manufacturers. Try using the RAM modules with the same make and type/speed.

put the largest ram closest to CPU central processing unit make sure that the ram are of the same brand/type some motherboards only accept a certain brand/type

Hi this model sopport 2Gig Memory Ram.

Please check in to your Bios system maybe share memory Video or capacity is setting

Turn the computer off.
Remove the battery.
Unplug the AC adapter.
Turn the computer bottom-up.
Look for a few screws that secure a small panel.
Unscrew those screws, and remove the panel.
If you've selected the right panel, you should see your current RAM.
On the LEFT and RIGHT edges, there are small "fingers" that are holding the RAM.
Gently pull those fingers away from the RAM, and it should pop-up slightly, and you should be able to remove the RAM.
Notice that the "notch" in the middle of the RAM is slightly off-centre.
Insert the new RAM into the socket, and gently press down, until those two fingers "click" to grab the new RAM.

Depending on your "old" RAM, you may have:
* one "occupied" RAM slot (1GB), and one "empty" RAM slot;
* two "occupied" RAM slots (512MB/stick).

So, you may have to remove one RAM stick, to expose an "empty" RAM-slot "hidden" under the RAM.
Or, the "empty" RAM-slot may be visible without removing the RAM.

Or, you may have to remove one of the 512MB RAM-sticks, in order to free-up a slot for the "new" RAM.

Replace the cover-panel, and screw it in.
Reconnect the battery.
Reconnect the power-supply.

Start the computer.
Click Start
Point at My Computer
Right-mouse click on My Computer
Choose Properties
It should display your CPU-speed and the "new" amount of installed RAM.

Most likely your system has UMA video (Unified Memory Architecture) which means that system RAM is used for Video. Many systems dynamically allocate RAM resources to the Video, thus you get the varying amounts of RAM accessible indicated. This is a normal function and system is working as designed.

Your motherboard has 64Mb built-in RAM and the video card needs some video RAM and has grabbed 8Mb of RAM which leaves the system with 56Mb of RAM. When you insert a 64Mb RAM module you have a total of 128Mb of which the video has grabbed 8Mb which leaves the system with 120Mb.
You can't change stop the video card from grabbing 8Mb of RAM, the RAM is essential for the video to work.
You can upgrade the RAM by removing the 64Mb RAM module and insert a 128Mb or 256Mb RAM module. You may even be able to insert a 512Mb RAM module if the motherboard will accept it, you need to check the specification of your laptop to see the maximum amount of RAM the laptop can handle.

If you know what mother board you have you could check what RAM it can use.

All RAM is installed in the same way, but different types of RAM are keyed differently. That basically means that one type of RAM (for example SD RAM) will simply not fit into another type of RAM slot (for example a DDR RAM slot).

To install ram on a PC
Please note - do NOT touch the connector side of the RAM, handle it only by holding the side or top edge
1. check that you have the right type of RAM. do this by lining up the RAM above the RAM slot and making sure that the RAM is the same length as the RAM slot AND ALSO that the RAM's key (the little hole or notch in the RAM) lines up with the key in the RAM slot. Note there might be more than one key
2. open both clips of the RAM slot by pushing them down and out from the center of the RAM slot
3. gently insert the RAM into the RAM slot
4. check again that the RAM and the RAM slot's key's line up, if they do, firmly press down on the RAM on both corners until both clips automatically click shut on the RAM

That's it! :-)
