I currently Have 2 sticks of GDDR3 2G ram installed and I went and bought 2 sticks of 4G Ram. 240 Pin.
I went to specs online and it said the Acer G45T motherboard uses DDR3 and when I search Gateway Eg43M motherboard it says it uses DDR2.
I put the DDR3 4G in(brought one of my old ram chips to computer dealer and he said what would work) and Computer would not boot up , all it had was a high pitch alarm sound. It says motherboard is good up yo 8G of ram also.
So I am a bit confused to witch ram I should use.
New to forums for computer help so I apologize in advance If I haven't given enough info.
Well first of all you should look in to your drivers. It could be that CPU-Z is messing things up, but it could also be that your drivers are outdated. If you are 100 % sure you have the acer motherboard then you should have no problem booting up the pc, if you boot with the 4gb sticks, do you hear a number of beebs ? If so, how many beebs did you hear ?
