I am going to be upgrading a office pc my dad uses, it currently has 2gb RAM in it 2x1gb sticks and i am looking to replace those with 2x2gb sticks, I don't wanna add any more cause its a 32 bit OS anyway. So the problem I have come across is this, on the website ( http://goo.gl/DVLWly ) they state that you can add "PC3-10600 DDR3 non-ECC SDRAM (runs at 1333 MHz)" so i went and looked on pc part picker for DDR3 RAM 2x2gb sticks running at 1333mhz, i found some nice ones and then i saw they of course were all 240 pin whereas on the hp website it stated "Two 200-pin SODIMM slots supporting dual channel memory" do they even sell 200 pin DDR3? if so link me please!
