Playing around with overclocking and would like to know how to safely increase my FSB/Bus speed.

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.

For Sandy/Ivy Bridge, simply increasing the clock speed of the CPU and/or RAM does something similar to increasing the FSB on say a Core 2 processor.

There is no FSB or bus. Just the BCLK. And systems gets very unstable just you raise it 5%.

Yes but actually I would like to raise the bus about 1% or 2%, and only for a minute until I save the benchmark (which is only CPU-Z). How can I do that? BIOS does not have the option.

There still aint no bus. Only the BLCK, and you might be able to find that in BIOS.

Your UEFI should look similar to this one. The value shown for Cpu Base Frequency is what you would mess with. You won't be able to go too high but if you wanna play around to see then have at it. I'd suggest dropping the multiplier down 1-2 from a stable overclock before you do it.
