I have a Hp p6212f and it comes with the ASUS Benicia motherboard with an Intel Dual core Pentium E5300 processor and has 6GB of RAM, uses Windows 7 64 bit Operating system. I am thinking of upgrading to the Windows 7 Ultimate or Professional at least so I can have both processors recognized by the operating system. I find that with this system as it is I can only expand the RAM to 8 GB even though it is said that the RAM capacity for Windows 7 Home premium is 8 GB while other computers similar, very similar are accepting 16 GB. Is there possibly another reason unexplained to the public as to why HP would hold the RAM down like that when that is the very reason that we are being moved into the 64bit arena?Then wouldn't that help hold down the amount of programs being open at one time which would assist the processors by not getting them overloaded with more work than they can accommodate with their limitations.It seems very complicated juggling services Could a Home Basic operating system possibly be disguised as a Home Premium which might account for the 8 GB RAM limit. That is the specs for RAM for a Home Basic Operating system and we know that a 32 bit Operating system has a limit of 4GB so they couldn't pretend to be anything too big. it seems to be a rather challenging job to present the windows 7 operating system and make it run on a rather limited power and component bank. I continue to find computer features that are new in windows 7 and aren't running at this time and I wonder if this system is overworked and incapable of making Windows 7 run on this computer. Just like I was told almost two years ago but havent received confirmation on this from HP. They are still stedfast that this is a good time to buy another new computer to replace this new computer. I think i will indeed pass, thank you. Should I hurry and buy another new HP computer like this? if I do please change my name to "Rocks In Head"
