Yes. 16 gigs is the maximum of 2 x 8 gig modules. Here is the applicable Service manual:
See p. 46. You remove the back cover to access the two memory slots and you would need two of these to reach 16 gigs.
Add another one of these to reach 8 gigs, probably the most cost-effective upgrade. Dual channel memory operation is not supported.

Many thanks - memory now installed - all tested out fine.
Note for others:
with 4GB - 512Mb is set for video (3.5Gb is available)
Now with 8Gb - 1024Mb is set for video and 6.95Gb is available to windows)
Once again many thanks for your advice - the tech manual on how to get the base off was an added bonus.
