are your sticks the same or different, i know there both pc 3200, and 184pin sd ram, hopefully the numbers match. Only certain ram works because the mobo, as stated on dell's site, capable of seeing 1gb, however there are many success stories due to investigating the chipset of the board and it was found that it is capable of seeing certain sticks, of ram.
Too bad shipping to Canada is extremely expensive w/ artbooks and such, or else I would have bite on probably on Xenosaga and Ar Tonelico Melody of Elemia
