I just updated from 1.25GB to 2GM 2 days ago and yes it is possible and as
other suggested, it may also depend on your mainboard.
And when I had 1.25 (1 + 256), it is as houstrained suggested, but I had it
done by the vendor to ensure everything is correct before taking the system
back.
So if you are not comfortable with DIY, just have the vendor do it for you
and usually it's free. Even I had been in H/W industry for very long, now I
don't do any DIY and just let the vendor do their job
Good luck.
