Some more testing with Silkcut demo: (on my PC 2.13ghz)

1) not crashes (cpu_throttle 0%) (SySInfo_v4.0: Mips=228.02, MFlops=236.98)

comp_trustbyte=indirect
comp_trustword=indirect
comp_trustlong=indirect
comp_trustnaddr=indirect

2) not crashes (cpu_throttle 0%)

comp_trustbyte=direct
comp_trustword=indirect
comp_trustlong=indirect
comp_trustnaddr=indirect

3) not crashes (cpu_throttle 0%)

comp_trustbyte=indirect
comp_trustword=direct
comp_trustlong=indirect
comp_trustnaddr=indirect

4) crashes (cpu_throttle 0%)
not crashes if cpu_throttle=-350.0 (-35%) (SySInfo_v4.0: Mips=512.61, MFlops=183.56)

comp_trustbyte=indirect
comp_trustword=indirect
comp_trustlong=direct
comp_trustnaddr=indirect

5) not crashes (cpu_throttle 0%)

comp_trustbyte=indirect
comp_trustword=indirect
comp_trustlong=indirect
comp_trustnaddr=direct

6) crashes (cpu_throttle 0%)
not crashes if cpu_throttle=-450.0 (-45%) (SySInfo_v4.0: Mips=406.70, MFlops=146.40)

comp_trustbyte=direct
comp_trustword=direct
comp_trustlong=direct
comp_trustnaddr=direct

7) crashes (cpu_throttle 0%)
not crashes if cpu_throttle=-50.0 (-5%) (SySInfo_v4.0: Mips=225.57, MFlops=237.53)

comp_trustbyte=direct
comp_trustword=direct
comp_trustlong=indirect
comp_trustnaddr=direct


Interesting cases for Silkcut demo when not crashes: 1), 4), 6) and 7)

In cases 1) and 7) SySInfo_v4.0 shows almost same speed, but in cases 4) and 6) it shows much higher in Mips with lower in MFlops !?

Could that mean that the case 4) is the best choice (regarding to much higher in Mips) or maybe cases 1) or 7) are better choice (regarding to higher in MFlops)!?

EDIT:
Comparing again cases 4) and 7) by running the Silkcut demo, obviously the case 4) run much smoother on my PC!!! (so case 4) is the winner)

EDIT2:
Let test & compare again cases 4) and 7) with sysinfo_v4.0 Dhrystones:

case 4 , cpu_throttle=-300.0 , sysinfo_v4.0 Dhrystones=557106 , Silkcut demo crashes!!!
case 4 , cpu_throttle=-350.0 , sysinfo_v4.0 Dhrystones=491279 , Silkcut demo still works!!!

case 7 , cpu_throttle= 0.0 , sysinfo_v4.0 Dhrystones=226448 , Silkcut demo crashes!!!
case 7 , cpu_throttle=-50.0 , sysinfo_v4.0 Dhrystones=217817 , Silkcut demo still works!!!

So, can we finally dismiss the impact of speed to the Silkcut demo crashing !? (491279 is much greater than 226448)
