Yeah you need two 1GB sticks in there to realize the real speed of your MacBook Pro. You dont' say if you have one 1GB or two 512MB sticks inside. You can add 1GB sticks one at a time if the latter is the case and money is a problem. Cheapest good ram is from Omni Optival via <http://ramseeker.com>. Wearch for MacBook Pro in theupper popup menu. Then click on the price link to the Omni site. If you go directly to Omni you will have to pay a lot more. -- Taylor Barcroft New Media Publisher, Editor, Video Journalist, Podcaster, Futurecaster Santa Cruz CA, Beach of the Silicon Valley URL http://FutureMedia.org RSS http://feeds.feedburner.com/FutureMedia iTunes http://tinyurl.com/8ql87 barcroft (gizmo) kungax (Skype) kungag5 (iChat-AIM) 831.477.1010 home-office talk to the machine, ringer's off, will pick up if in 323.819.5659 cell - Verizon On Jun 22, 2006, at 9:23 AM, Robert MacLeay wrote: > On 6/21/06 2:21 PM, "eleventhvolume " <colin at eleventhvolume.com> > wrote: > >> I own a 15" MacBook Pro with 1GB RAM, latest OS version.
