In the testbed department there's not a lot that has to be said as everything is fairly well covered in the image above. Because of that, we'll get stuck into what's going on with the overclocking side of things.
While the DX79SI BIOS isn't my favorite BIOS by any means, we still get a strong option of overclocking. With the heatsink design being a little more tame, though, compared to some other companies we didn't want to go crazy with the voltages.
Setting the 1.25 Host Clock Multiplier that pushes our BCLK to 125, we found instantly the board wouldn't boot. Getting back to default and into the BIOS, we ended up just using the multiplier to find our overclock.
We ended up and running in Windows at 4.5GHz which is a nice little overclock, but by no means the best we've seen to date. This was done by leaving the BCLK at 100 and just pushing the CPU multiplier up to 45x. Moving to the next level, we found ourselves staring down the barrel of some instability and 45x really seemed to be the sweet spot for the motherboard.
While not a huge overclock, it should yield a nice boost in performance over the stock clocks which is exactly what we'll find out today.
Let's get started!
