I bought an AMD Athlon X4 840 to use in a headless server, but I can not get the system to boot without a GPU connected.
I used another CPU/APU (A10 5700 with integrated GPU) to install the system and setup remote SSH login, but when I swap the processors the system will not boot.
Is it correct that the Athlon chip should not boot without a connected GPU or is the cpu faulty. It was delivered with a bent pint that I had to bend back before installling it, so that might be the cause if the cpu is supposed to be able to run on a headless system without a GPU.
Thanks four your input!
