6gb 1066mhz ok with X48 DS4

[mozart134]

Hello Recently brought a X48 DS4 motherboard (updated the bios) with 2x2 Hyper X DDR2 1066mhz ram (4gb in total) works like a dream. However, I've just brought a further 2gb (not singles, one lump sum) of the exact same memory(5-5-5-15 timings) increasing it to 6gb. The question is, does it matter where I put the additional 2gb of ram?, is there a specific ram slot I should put it in - since the other ram is using slots 1 and 3. Also will the motherboard use it as triple channel memory? and if yes will it increase the overall bandwidth.

Thanks Robert
