Edit 9/8/2016: Originally I thought the P2221sc computer can only handle up to 4Gb of RAM and not 8Gb. Looks like the M2N68-LA Narra6 board in that computer can handle 2x4Gb RAM sticks that totals 8Gb. And here's the new link to the specs of the M2N68-LA Narra6 board. The HP and Crucial RAM web sites seem to be wrong (and misleading) on the max amount of RAM as noted in this HP forum thread.
The M2N68-LA Narra6 board uses DDR3 RAM chips, not DDR2 chips. There's a physical difference between the DDR2 & DDR3 chips and the "notches" are placed in slightly different places between the two. And older "revisions" of the M2N68-LA boards (like Narra5, Narra3 & earlier) use DDR2 memory chips.
