im rurbing pc for my uncle. I want to install an E8600 as an upgrade. I have checked HP and intel.ark websites and that is a go. I need to know if I can also upgrade ram to DDR3 from the current DDR2? current ram is 800MHz, where DDR3 is 1333MHz. I believe this is ok, reason: the new cpu has 1333MHz FSB and uses DDR3. also, could I use 8gb instead of the current 4gb max? I have asked in HP Forum and got a canned B.S. answer pointing me to website I had just read. Please help. this is a fathers day gift. thank you all for help.
Sorry bro, your motherboard only supports CPUs upto Core 2 Duo E6xxx series. You cant install any E8xxx CPU in it.
And no you cant upgrade RAM from DDR2 to DDR3 as your motherboard can only have DDR2 memory installed in it. And that is also one of the reason why you cant use E8600 CPU in it, as E8600 is made for motherboards with DDR3 while your motherboard only has DDR2. And no you cannot have more than 4GB because thats the maximum your Motherboard supports.
I suggest you to sell that CPU and buy a new PC for him otherwise I suppose you can do nothing other than just changing the CPU to a E6xxx one. Hope it clears your doubts.
