I have checked on serveral forum treads, and some claim that this model is hardwired use only 4GB RAM, while other say that it is possible to upgrade to 8GB RAM. Please help me

These two sites claim that my computer model and motherboard can only have 8GB RAM:
Memory Upgrade HP Pavilion p6221sc Computer Pavilion Upgrade HP Memory RAM
Motherboard Specifications, M2N68-LA (Narra6) | HP®-støtte

Specs:
Computer: HP p6221sc
Motherboard: M2N68-LA
Windows 7 Home Premium 64bit
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.

Actually Max Support Ram Is 16GB

I know this post is old, but for anyone searching in the future the max supported ram for the narra6 is 16GB though I do believe I read you had to have windows 7 professional or windows 10 professional to unlock the 16GB... I could be wrong on this.

16GB on a narra6 = Mind Blown!

well, you did not say which version of the M2N68-LA board that you are using, zoziano.
do you have Narra3 (REV 3.02), Narra5 (REV 5.00) or Narra6 (REV 6.00 or higher)?

zerodegrees536 is using M2N68-LA board revision 6.00 (Narra6), which uses DDR3 RAM sticks and seems to handle 16Gb of RAM on his computer.


Narra5, Narra3 & older versions of M2N68-LA use DDR2 RAM chips instead


I, on the other hand, am using M2N68-LA board revision 3.02 (Narra3) [HP part # 5189-1661] on HP Pavilion m8417c, which uses the older DDR2 RAM chips but can handle up to 8Gb of RAM (currently I have two 2Gb DDR2 Crucial and two 1Gb DDR2 Samsung RAM sticks for a total of 6Gb - I may replace the two Samsung brand RAM chips with another pair of two 2Gb Crucial memory chips later on to increase the total of 8 gigs - my board has four DDR2 RAM slots)


the newer M2N68-LA Narra5 and Narra6 boards have only two RAM slots but can use higher capacity RAM sticks
