AMD A8-3870K Black Edition & Hybrid Crossfire Review
HD6670 (Hybrid Crossfire)
Asus AM1 F1A75-M Pro

As always we start by seeking the highest multiplier available, which for the A8-3870K is x38.
The highest Bus Speed we were able to obtain is 160MHz.
So in total we managed to overclock the A8-3870K to 3.6GHz, a nice 600MHz increase over the stock chip. At these speeds the CPU topped out at 68°C, which is not too bad at all.
Of course the CPU isn't the only thing that is available for overclocking, or indeed the only part we need to take account of when ensuring we don't become thermally limited, and the integrated HD6550D GPU can be pushed from it's default setting of 800MHz up to 960MHz. This is the speed that we'll be running our overclocked tests at, including the hybrid Crossfire ones.
