Dude, no doubt it is a good overclocking result, except the RAM timing part

I'm not sure if you are going to use this PC for long hours and yr lifespan expectancy (must be workable for 2-3 yrs or wat). Let's assume u r concerned about hardware stability and lifespan, here are some suggestions:

1. CPU vcore no more than 10% from original Vcore, or for even safer play, AMD recommends about +0.05V from default. Well, this is only if u wanna use tat PC for 8-10 years, so IMHO, 10% is good enough bcoz it gives u about 0.12V increment from default.

2. Tighten the RAM timing. Run it at DDR450 / DDR466 using fine tuned tight timing might give u much better results than 3-4-4-x or even 3-7-7-x @ DDR560.

3. Make sure yr system is stable, bcoz multimedia content creation software is as stressful as SuperPI. I am sure u dont want any error in yr results, or yr software suddenly auto close / BSOD when the encoding process is near the end
