my hp pavilion has got 256mb in it and i want to upgrade it to 1gb.problem is according to hp it has a 256mb ddr sdram pc2700 333mhz in it!but some shops are telling me to use 2x512mb pc2100 266mhz and not the pc2700!!so can anyone tell me what is the right one.
Have you got your mobo manual if so this will tell you which RAM your board supports as it is feasible that your board supports both types you list. If not you could google the make and model number of your board to find it they are marked on the board somewhere.
Whichever RAM you end up using make sure you use the same type in all your slots as memory conflict probs can be a bugger
found the model of mobo on the hp site but they are two versions of it? a north bridge chipset 333 mhz and a south bridge chipset 266 mhz what ever that means!! how do i find out what version is in my computer.
