    I had 512MB memory in my Fujitsu PC, I want to upgrade to 1024 MB, I bought 2x512 Mb DDR PC3200 400MHz chips but it doesn't work, am I doing something wrong. In the beginning the PC started with new DDR memory and I could work with it but now it is over, it didn't start anymore. I put my old memory back and now it works again.

DDR & DDR2 memory DIMMs are not interchangeable.

Check the specs on your motherboard; some motherboards require specific memory configurations, such as my mobo, which will only function with "x8" memory chips, such as 32Mx8, 64Mx8, or 128Mx8. A "x4" memory DIMM will not work -- this might be the problem you're having. (Unfortunately, this bit of data on memory is often not listed, so you may need to ask/search well...)

No, DDR400 is just DDR RAM. DDR2 is newer RAM and is not compatable with older systems that take DDR RAM. Sorry.

I have a Fujitsu Siemens Computer Bought from PC World. A couple of years old now. It has become very sluggish on start up and I suspect I need a memory upgrade. I don't know what memory type to buy. ...

-your computer piles up data overtime that would cause your computer to slow down.
-you install/uninstall programs once in a while and that adds to the problem.
-you can use any cleanup tool like CCLEANER. You can download it from this link,

Fujitsu Siemens GA-8ISXT-FS, can I add a 2nd ethernet card / NIC

The P/N GA-BISXT-FS is a Gigabyte mother board which has 5 availble PCI slots.
If you don't see any open slots, chances are that all 5 of the slots are already in use.
Take a look and maybe you can pull out of the cards you don't need and install the 2nd NIC card.
Good Luck and let us know how it works.

Can i upgrade my ram to ddr3 if so what would you recomend .cheers

Thank you for the clarification sir.
NO, the Fujitsu Scalio 600 Media Center uses the Gigabyte GA-8ISXT-FS motherboard, and it only supports DDR Sdram.

This is a PDF Motherboard Manual for the GA-8ISXT-FS mobo, from Fujitsu Support,

This is the support page for the Fujitsu Scalio 600 Media Center,
from Fujitsu Support,

Uses either DDR Sdram at 333MegaHertz, or 400MHz.
(PC2700 and PC3200 respectively)

DDR Sdram has 184 gold plated contact pins on the bottom.
DDR2 Sdram has 240 gold plated contact pins on the bottom.
DDR3 Sdram has the same amount of contact pins as DDR2.

The voltage and signal contact pins are in a different place, from DDR2 to DDR3.
This is why the locating notch on the bottom of the ram stick, is in a different place, comparing DDR2 to DDR3.

So you can see, DDR3 not fit in a DDR2 slot, because the locating lug in the bottom of the ram slot, and the locating notch in the bottom of the ram stick. Keeps people from trying to put DDR3 in a DDR2 slot, and vice-versa.

You can also see why a 240 pin ram stick, will not fit in a 184 pin ram slot.

Bumping up from DDR to DDR2 does make a difference in my book. (Requires using a motherboard that supports DDR2 however, so you would need a different motherboard)

Going from DDR2 to DDR3? Not so much IMHO. The frequency rate is higher, but there is a trade off with slower ram timings.

Sorry if I have been too 'Windy', but I thought I would give you more information, than just,
'No, won't work', or No won't work because your motherboard uses DDR Sdram'.

Can I use DDR2 800 MHz RAM on GA-K8NS-Ultra-939-Socket-939 MBoard

I don't think that that motherboard will accomodate the DDR800 you probably need a DDR333 or DDR400.
Calling the manufacturer support will render better information because they made the board. The memory you refer to may not fit the slot for this particular motherboard.

I wish to upgarde to the fasted CPU possible for my motherboard

More importantly RAM will give you better performance, if your computer is low on ram it doesn't matter much what the cpu is.

you can put up to 4GB of ram into it
4 x 184-pin DDR SDRAM DIMM socket support up to 4 GB
Support DDR400/333/266 unbuffered DDR SDRAM

here is a list of supported CPU's

I think any of the dual cores on that page will be a OK upgrade.

So if you upgrade your ram to 2GB and a Dual core 4800+ that should be good. but in the long run it might be smarter to upgrade to a new motherboard and even faster cpu, with DDR 2 memory, the memory ddr2 is really cheap these days.

Ram upgrading procedure

DDR-400 (not ddr2) PC-3200 You should look for Dual channel memory and put them in in matching pairs. The maximum amount is 4GBs Also consider looking for the lowest density you can buy. 2 -2.5- 3 is good
I like to purchase from they are fast, reliable, decent price, and have a great selection of goods.
The colors of the slots are to mark the channel pairs, so you know how to put them in in matching sets. Oh and when you boot up the first time your computer will stop and tell you the the amount of memory has changed- just click on F1 to continue.

If NewEgg interests you just click on the link is set to take you to the correct page.
Hope this is what you wanted to know,
please leave rating- thank you kindly

Can I install DDR3 RAM chips on my laptop?

Sorry to say but that is not possible upgrading the RAM using a different RAM chip will not work, since your MOBO only supports DDR2 of RAM but if you just want to make the computer work faster you go and upgrade the DDR2 RAM up to 4GIG....
