Step 1) Maximize Bclock Frequency
Isolate the bclock from the CPU

First you need to isolate the bclock and find its stable limit with your chosen cooling. In order to isolate the bclock from the other components, the first thing you need to do is manually force a low multiplier for the CPU. For example; at stock speed, an i5 750 runs on a 133MHz bclock and a x20 multiplier which results in its stock speed of 2660MHz (133×20). Raising the bclock to 200 with the stock x20 multi would result in 4000MHz for the CPU, which you’re not quite ready for yet. If you are shooting for a 200MHz bclock, then a safe choice for now might be a x12 multi, which would result in a CPU speed of 2400MHz if you were successful in reaching your 200MHz target bclock. Doing this isolates the CPU from the bclock so you can focus on only bclock overclocking in this step. In some situations, x12 may not work, this is just an example though, so don’t be afraid to try other low multipliers if x12 doesn’t work.
Isolate the bclock from the memory

The fastest rated speed for memory on P55 with an i5 750 (for example) is DDR3-1333, which is a clock speed of 667MHz (dual data rate “DDR” doubles the bandwidth to 1333-like speed). Just like the CPU, the memory receives its clock from the bclock via a multiplier, in this case x5 (133×5=667). This is most often expressed in the BIOS as “2:10″. If you were to overclock the bclock to 200MHz as described before, your memory would be running at 1000MHz (DDR3-2000), and beyond the specs of all but the most extreme memory. To isolate the memory from the bclock, lower the memory multiplier to the lowest setting available, most likely 2:6. If you were to reach your goal of 200MHz bclcok frequency, your memory would only be at 600MHz (DDR3-1200) and well within the capability of all but the worst DDR3 on the market.

at 12x200 change RAM Frequency from auto to 1600Mhz and up the voltage from auto to 1.65v. It will only fail to boot if your RAM is bottom of the barrel. If it doesn't boot change back to auto.

Then 20x200 and start testing for stability. If it passes something like IBT then 21x200 and if that 22x200. If it boots but fails IBT up vCore slightly (~+.0125v) and try again. Call it a day when it's stable and your happy with the results.

EDIT:

Set LLC to Enabled, Spread Spectrum to Disabled.

EDIT2:

And turn Xtreme Phase Full Power Mode to Enabled.

I'm waiting for Phanteks to release this case, wow:

There is one major short coming to it though: it can only do microATX. If they released an ATX version of this case it would be really nice. I like the dual exhaust on the back panel and the interesting mounting location for the PSU. This case has some interesting ideas. Also mounting two fans on front intake and two fans on back as exhaust seems really interesting to me, it gives a linear airflow. I wonder how good this case is / performs. It probably won't be cheap though, heh.

I really, really like Phanteks cases.

NCase M1 is probably the most glorious small-form factor case in existence if you're into elegance of design and stuff like that

i7 costs a lot more than i5 for that ~20% extra encoding performance at same clock speed. Also, 4770k is last-gen.

You don't need to buy an unlocked CPU or a CPU cooler if you can't overclock anyway because of the mobo

no need for 500 watt PSU, or super high quality for just a streaming rig.

No need for good/expensive case for streaming rig

4gb of RAM would probably work fine

Doesn't ASRock have motherboards with HDMI in? you could just use that instead of a capture card. Save a lot of money.
