The ram arrived today.

First time I tried it the computer wouldn't boot,second time it did boot and showed a memory change.
I read somewhere you need to press the ram cards hard (but not too) in the slots so I tried the 1GB again but it wouldn't work.
I did notice the 512 cards had slightly ticker connectors than the 1Gb as I was pushing them in.
Btw I then reinstalled the 2 x 512 and computer booted but showed only 512 ram...I then rearranged the cards (I think?) and then it booted but with a memory error...shortly after it booted fine though showing 1 Gb of ram.
Took everything out again and reinstalled and now it boots showing no memory error and the correct amount of ram.
So...seems my ram slots are a bit eccentric...
I checked for dust but didn't find any btw.
Ok I'm running 1 Gb (wow...

) of ram now with a Pentium M (1.5) processor on my laptop (Windows XP Home).
It does improve the overal perfomance at a first glance.
I now wanted to ask should I reconfigure my virtual memory now that I've added ram?
