Overclocking my APU

I currently have an A8-3850, came as 2.9ghz stock speed and the stock HS/Fan combo, and I have been running it at 3.2ghz thru the bios settings. It seems to doing just great so far but I haven't really tried to stress it yet...

Has anyone had good (or bad) experience with this APU in particular ?

I also have my Radeon 6670 running with a 12% oveclock thru the Catalyst Control Center (latest version...14.4 ?) settings and it seems ok also.

My next step may be changing the settings on my 8GB of Ripjaws 1600....What is the best thing to do there....

PS...this is NOT for gaming use, I merely would like to squeeze some extra performance out of these components without having to buy new ones.... but OTOH I dont wanna fry them either 🙂

And my case has 4x 120mm fans (front, back, 2x top) as well as vented side, front and rear panels, so I don't think cooling should be an issue at this point

Any advice/suggestions appreciated !

I've played extensively with llano/A75 overclocking and that vid card. The main issue will be the motherboard/bios in most cases when seeking a high overclock.
Depending on the board you got the VRMs can get a little hot. You lack higher than 1866 mem speed and there is usually a big window of instability between 110-133fsb (varies by mb) usually presenting itself as sata or usb errors. Some boards just won't boot or the bios will even corrupt if you try for higher fsb speeds.

I'd suggest stability testing to first find the lowest voltages you can stably run the NB, GPU, and CPU at.. Undervolting + overclocking is easily doable and lowering the voltage will give you a bit more headroom heat-wise. Most of these chips i've had top out around the same 3.4-3.5GHz. Raising any voltage above stock has never helped me get higher clocks, more often it hurt.
The settings in my sig are a 3870, pushing any higher just isn't worth it stability wise.
