Question Cant POST if RAM more than 2GB

[mstrap123]

I previously had a 4gb ram installed but when the ram died, i tried to switch the ram but after that i install the ram, it does not POST and no beep sound at all. It POST and boot successfully when i only install a 2gb ram, i tried installing 2 2gb ram and it does not POST or boot as well. It seem like the mobo only accept 2gb of ram installed.

If these are mismatched pairs of RAM sticks then that is why. RAM is sold together in kits for this reason, they are tested at the factory and matched together to work.
