I think 2 cores get shut down I think. And the remaining 2 gets bumped up. Games that support multiple cores will suffer.

Turbo mode only activates when only 2 cores or less are being stressed.

This is not true.

Turbo-mode only adds 1 multiplier to core #0.

Nope. The i5-760 overclocks core 0 to 3.3ghz when the stock BCLK is 133mhz. Thats an extra 4x to the multiplier.

Also, the amount of multiplier added with TB varies to the amount of load on each core.

High Performance : Bus speed 133.8 Core Speed 3211 mhz Multiplier x 24 DRamFreq 800Mhz
Turbo Mode : Bus speed 147.9 Core 3549 mhz Multiplier x 24 DRamFreq 888Mhz
in turbo mode it didnt add any extra multiplier it remain x 24 only the bus speed is increase
not just in games but in GPU Tool Stability test aswel. fps is reduce 10 - 20.
very odd stuff here.
could it be that my memory clock is too high after turbo mode and experience error?
