help! adding ram to EP-4BDA! what are the ram limitations?

[EdipisReks]

i vaguely remember hearing that the intel 845D chipset could only address 3 lines of ram, with each side of a stick of ram counting as a line. something like that, it's really vague in my mind. i want to add a 512 stick of samsung pc2700 (to bring my total to 768), but i want to make sure it works since my current stick is double sided. i can't find my manual anywhere, and the EPoX website wasn't very helpful during my, admittedly, cursory scan. will i have a problem adding another double sided stick of ram? the website did say that the max was 2GB, which makes me think that i'll be fine. thanks for any help you can offer.
