Thanks for your quick reply rdave13. I tried running the crucial scan but it replied that Crucial does not have any available upgrades! Can I infer from that that the motherboard does not support more that 1Gb of RAM?
I have an old laptop that I am resurrecting. I bought it about 2005 sold by Tiny computers who went bust some years ago so finding it impossible to find out any info on it. I was running Windows XP had total of 1Gb Ram ( 2x 512Mb modules) I have just installed Windows 7 on it, but it runs very slowly so I would like to increase the RAM up to 2 GB. The existing RAM modules are PC2700s DDR 512MB so I purchased 2 x 1GB 330Hz modules but when I installed them in the laptop nothing is happening, so I suspect they are not the correct type, or is it that the existing hardware is not capable of using them. Forgive my lack of knowledge, I am just trying to learn about computers so would very much appreciate any advice.
serbius: You can assume that Crucial no longer stocks RAM suitable for a laptop of that age. I would guess that 2GB is the upper limit but I doubt that you will find any available anymore.

The above post is a scan which i did using CPU-Z software. Hopefully that will be useful to someone.
Thanks for your reply Wee eddie. The new RAM modules I installed were 2x 1GB DDR 330Hz PC2700 which I thought would work, but apparently not!
rdave13 I will give it a go installing a 1Gb +512Mb module wont take long and report back shortly.
rdave13 I did remove one of the 512Mb Ram cards and replaced it with one of the new 1 Gb ram cards, but now although the laptop is working o.k when I look in the System information it's reporting only 1Gb or Ram installed. so possibly the limit on this old laptop is 1Gb?
Oh well, I have learnt a lot from this exercise, onward and upwards, Thanks for your help, very much appreciated.
rdave13. I am presuming that the reason you suggested those O.S systems is that they don't require so much memory, and would therefore be more usable with my old laptop's hardware?
rdave13 Firstly I want to report that I have been trying different combinations of the old & new ram cards, I now have 1 of the old 512Mb cards and 1 of the new 1Gb cards installed and the System is reporting my Ram as having 1 1/2 Gb (1.5Gb)of Ram installed. I need to try a few more combinations, but it might be that one of the new 1GB cards I bought is faulty?
Thanks for the info on the linux stuff, I will consider trying one of them.
