Waltchan, you said you got your A4-3300 up to 3.1Ghz on this ECS A55 board.
HOW???
I tried setting CPU overclock to Enabled, changed the bus freq from 100 to 105, it booted Win7 64-bit, I ended up with 2.625-2.630Ghz.
So I tried 115, and had to clear CMOS, couldn't even boot BIOS.
Tried 110, couldn't boot Win7.
Tried 107, couldn't boot Win7.
So what's the secret?
I tried enabling the IGD OC feature, and then changing the freq from 600 to 400 (attempt to underclock. Likewise, I tried setting the memory freq. to Manual, and set it to 667. No go.)
Edit: Btw, is there any issue OCing when using the HDMI-out on the mobo? I seem to recall some issues OCing certain platforms while using the HDMI output wouldn't work, you had to use the VGA-out. I forgot which platform though, maybe AM1? Is FM1 the same way?

The second link mentions setting SATA mode to IDE. I'll try that.
Edit: I got it to boot one time at 115, but now I can't. Also, restarting and attempting to enter the BIOS again was fruitless. I had to power-off at the back of the PSU, and then try to boot again. Had to Clear CMOS several times when attempting 115, because it wouldn't even boot to BIOS. Unsure if that was an HDMI issue, or what.
I'm through trying to OC this machine, FM1 is garbage for OCing.
