The panasonicCF-73 tough book I am using has 256 RAM, can I increase this to 1gb or 2gb? Thank you,

Hello here is the homepage:

Your mainboard supports:

2 DDR DIMMs
Supports DDR266 / DDR200
Max. 2GB

You can easy add 2, 1gb modules.

I recommend 2 gb ram.

Good luck

It will be compatible but it is recommended, you use same type of modules(RAM)
ie 256 MB + 256 MB
1GB + 1GB
Plus the advantage of using two instead of one(If you want 2GB, go for 1-1Gb two modules, depends on you) are, if one fails other works.

you need atleast 2gb to run 400 ram.

The 2 1Gb RAM are either the wrong type or they are incompatible.
Try to use the same brand and speed as the 256 Mb RAM that was installed in your Dell.

You have 2 ea 512mb =1gb installed now

You need 2 ea 1gb = 2gb

2gb is the max

You must have 2 of the same sodimms installed.

If the manual says this motherboard support up to 1 GB RAM, you cannot put 2 GB. You can put 2x 512 GB RAM or 1GB RAM
Also try to upgrade your bios, maybe a better bios version supports more than 1 GB RAM.

Hi

Yes you can use upto 2gb of ram max.

you can use the 1gb ram in single slot.

With Regards

Hello,

You can use two 512Mb sticks which will equal 1024Mb or 1Gb.

Hope this helps.

YAS IS GOOD YOU CAN UPGRADE YOUR MEMMORY TI 1GB ALL YOU NEED TO DO IS GET THE EXACT TYPE OF WHAT YOUR MOTERBOARD IS USING eg IF YOUR MOTHERBOARD IS USING DD RAM GET 1GB DD RAM IF IT SD RAM YOUR BOARD USES THEN GET SD RAM. IT GONNA BE FINE WHEN YOU UPGRADE IT WILL PARFECT YOUR PC PERFORMANCE.

PC1600 runs at 200MHZ and PC2100 runs at 266MHZ..

Since your motherboard only supports a max of 266MHZ, I would recommend that. (not to mention that PC1600 is pretty much obsolete)..

2nd, you motherboard supports a MAX of 2GB Total ram.. So, you could install 1GB + 256MB.. But why not go for 2xGB?

The price for a 1GB stick of PC2100 is around $75-125 CAN. Not soo cheap anymore...
