I have a a10-5800k running at stock voltages with a 6670 dual graphics setup.
When playing games, I found it strange to find dips in the framerate. It would happen in either an DX9 or DX11 game. At first it seemed periodic, something that I could notice in the System Monitor, but now having launched CPU-Z, I see that the NB frequency is dipping from 1800MHz to 1400 or 1500 MHz. This is when the system is idle.
As for my CPU temperature, it hovers around 30C idle and 50C under load.
Any ideas to stabilize the NB frequency?
