Don't get hung up on looking for just PC2700 as PC3200 will likely be a bit cheaper. It may have a faster spec than PC2700 (166 vs 200), but it will work just fine at the slower speed. Also from that first screen shot you may have PC2700 installed, but it is only running at PC2100 (133) speed.
P.S. What is the make and model of the motherboard in question?
