It is for my system in my signature.
Assuming you're running a 3770, for all intents and purposes, you shouldn't be tweaking the BCLK if you decide to overclock. From what I understand, you would only get ~5% out of your BCLK if you decided to overclock it. I know some people have reached higher BLCKs but again, my point is that BCLK overclocking is largely dead after Sandy Bridge and beyond. Instead, you should be tweaking your CPU multiplier. Leave your BLCK at 100.
If you already knew this and you are dead serious about overclocking your BCLK, then sure, the procedure is pretty much the same as if you were overclocking anything else: bump the value up, run tests for stability, rinse and repeat.
