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?

Thanks

Thank your for the advice, but there is no progress.

Disabled cool and quiet : same problem.

No C6 : same problem.

I have tried downclocking the CPU to 2800Mhz : same problem.

DDR3 down to 1600Mhz : same problem.

I could force a downclock of the NB frequency to 1400Mhz, but that really isn't what I want to do!

When using dual graphics, the problems exists on both using the output of the discrete card like and the motherboard`s iGPU output.

If I disable dual graphics and use the iGPU alone, the drop in framerate in a game is very apparent and so jerky it is almost unplayable.

Is this a CPU problem or a motherboard problem?

MSI stopped answering my support requests as I asked for diagnostic software other than CPU-Z.

When I reported this problem to AMD, customer support immediately issued an RMA. Unfortunately I had to pay for shipping to send the APU for replacement, but I wanted to resolve the problem. Here in Canaduh, the cheapest shipping to the service centre in Florida was $17. This felt ridiculous considering the APU goes for $120, but the NB frequency issue needed to be resolved.

After a couple weeks, I received the replacement APU. Sadly it became apparent that the problem was not with the APU (unless the replacement is at fault as well) but in fact the motherboard. The MSI FM2-A75MA-E35 is at fault.

AMD and hardware(motherboard) manufacturers should provide end users with diagnostic software to avoid end users wasting time and money.

It is a Windows 8 problem... A new install of Windows 7 and the NB frequency is stable.
