1) You may need a 2B5 revision board for it to work (the last revision)
2) You may need paired RAM (identical memory sticks, paired by the manufacturer)
3) You may need memory of a certain type. I guess the only way is to try? Genesi used "Kingston kit ram with blue heatspreaders", model number KHX3200AK2/2G
,

Ok this is iirc

1) Operative word is "may" with newer OF I think older boards would work

2) Generally yes you want matched pair for timings.

3) This is true but Kingston wasnt the only Ram Genesi used. There were several iterations of "odw" the first version that went to motorolla and other clients/partners had Samsung PC2700 (for timing for whatever reason worked really well no errors)
