My laptop - Toshiba A135-s2276 (released in feb 2007)
Is it possible to determine for certain if my laptop supports dual-channel memory??

Currently it has 512mb and am thinking of adding another 512 (if it supports dual channel)

other users of the same laptop reported that cpu-z doesn't show any indication of dual-channel.
Any way to be certain of this? Its a new laptop so i am hoping its supports dual-channel.

Your laptop can be upgraded to upto 2 gigs of ram. However, it doesn`t support dual channel memory operation.

If you need further info, you can phone Toshiba on 800-457-7777.

^^ Thanks for replying! Can I know how you got to know this?

I looked at your systems specifications all over the web and couldn`t find anywhere that said your laptop supported dual channel memory operation. I therefore concluded that it doesn`t, since dual channel is a feature that I would have expected to be plainly pointed out.

However, I gave you Toshiba`s telephone number, just so you can find out for sure. ;)
