My definition of a solid overclock is as fast as it will go for as long as possible. In that situation, bumping the TDP up to 180 is a good place to start testing.
Yes, but not on my mainboard :D Thats the problem. Otherwise the x5650 would be enough. That was general information to help others who may want to try this. They are socket 1156 CPUs. When I first posted that I wasn't aware the i5 655K was 2 core so I added that info as a clarification. The...

Anything less and my W3680 was throttling in the TS Bench test. For Prime95, I had to go higher than that or else the multiplier would be throttling. For gaming I am sure you can get away with a lot less than this. For maximum performance, you have to significantly increase the TDP limit.
You are not using different multipliers on different cores. This setting controls what multiplier the CPU uses based on how many cores are active. When 1 or 2 cores are active, if you have this set to 31, the CPU will use the 31 multiplier. Any core that is active can end up using this multiplier in this situation.
