Hi Bronzen...

According to the HP website: 1280MB DDR SDRAM (1 x 256MB, 1 x 1024MB) Memory Max 1280MB DDR SDRAM (1 x 256MB, 1 x 1024MB
Memory Max 1280MB DDR SDRAM (1 x 256MB, 1 x 1024MB

hello, here's a part of the spec from the hp website. It looks like you've got 256mb on board memory and one expansion memory slot in which you can fit a 1024mb card, giving you a max memory of 1280mb (1024+256).
Hope this helps!

You have 1 available upgradeable slot expandable to 1,536MB. Optional expansion memory: PC2700 (DDR 256MB/512MB/1024MB) SODIMM: Memory compatible with PC2700 DDR333

1GB Of PC2100/PC1600

According to:
http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=bph07843

The M45-S169 only has one available memory slot.
(I'm confused about your post that states "M45-S265" in the head line).

• Configured with 512MB DDR SDRAM (both memory slots may be occupied)
• 512MB(min)/2048MB (max), 256MB on-board memory with 1 available memory slot for 256MB, 512MB, or 1024MB PC2700 DDR 333MHz SDRAM 2.5V SODIMM memory modules

You can find the complete specifications here.

yeah thats a normal issue with the dimension 2400 as the older bios only supports a max of 1gb of memory you will need to go to the dell website which ive linked below and get the bios update which will give you support up to 2gb-pc3200 ddr memory

yes

go to controlpanel -settings -hardware manager -search for new hardware. automaticaly your system deduct.it as 1024mb. ok try it allthe best.

Some MOBO support different type of memory modules like ddr 400, 333,533 and other, if your computer is working fine with that PC400 it only means that your MOBO is compatible with it. Since you're planning to upgrade the memory just get another PC400 because the memory should be the same to work fine.
