I was trying to overclock my A8-3870K desktop yesterday. I am using a A75m-ITX motherboard and AMD branded RAM. Memory is overclocked to 1866Mhz using the BIOS/UEFI option.
To overclock the APU, I used the multiplier option in the BIOS/UEFI. I was able to run successfully up until 3.8 Ghz and then I tried to go to 4 Ghz and now the machine won't post, nothing on the screen and no beep while it posts. I tried to remove the motherboard bios battery. No luck with that. Conputer won't post. I can hear the two internal hdds for data spin up. No idea if SSD is powered up.
Other specs; No extra graphics card. Antec EA-380D PSU.
Thanks in advance to any inputs on how to revive my machine.
Try moving the cmos jumper on the mobo - your manual will show you where it is and what position to try. I tried to pull it up online but ASRock sucks for hosting their manuals, I haven't been able to get one from them in weeks.
