Ram won't work with board please help!

Also, the other stick won't work either because it only supports 1gig per slot.

I'm officially never buying an acer. Since my first post an hour ago I've been looking for the spec sheet on their website and only just now found it.

Oh, heres another good answer. It only supports 2gb of ram at the most. Leave the bios alone. I think we got an answer.

2GB? I saw 4gb max either both of us are tired, or we're getting 2 different mobos here..

Nevermind i saw the spec sheet - yup 2GB max. case closed.

Grim has it right!

Buy a new mobo is all I can suggest. If you live in the USA newegg.com is the cheapest place to go for computer parts.
