I gained a further 300 3dmarks and a few fps difference in Bioshock by doing the above, I noticed my CPU (Q6600) was running at 1600mhz in windows and it would throttle up to 2400mhz when something started to happen then drop back down again - obviously this was happening during games and benchmarks too so I disabled the two options in the bios and noticed an improvement!

Just something others may find interesting :)

Also the cpu temps have not changed one single bit, it appears that C1E/Speedstep just drops the multi on the cpu making it run slower so consume less energy but the voltage draw remains the same (?) hence why the temps are unchanged.

Core 1 and 2 are warmest at 39-41 abd cores 3 and 4 run at 35-40 :)
 
I'd say 300 is within the standard deviation of that benchamark.

Run it 3 times with speedstepping and 3 times without then take an average.

I was unable to find a difference in any benchmark with speedstepping enabled. The core bumps up to 2400 in an instant.
 
Just thought I would share my experiences here. I have tested my Q6600 with and without speed step enabled and there is no performance difference. Running superpi to 1m decimal places still comes back with a 17 second time. 3DMark 06 actually scored slightly higher after having Speed Step enabled.

I have personally left speed step enabled because it runs cooler and there is no point in your processor running at full whack when it is not doing anything. 300 3D marks is virtually no difference at all, it could have been any number of factors effecting the results.
 
Well the cpu didnt change temp at all going from 1600mhz to 2.4 when throttled so I guess I could OC - 3ghz? :)

Everest Read benchmark once with C+Q disabled, once with it enabled

FYI - the top result is with C+Q turned OFF
the bottom with C+Q tuned on.....


not all benchmarks behave how you might expect....

That's crazy :o
And that proves once again how much Intel need to get their memory controller optimized.
 
Voltage draw drops form 1.2v to 1.0v on my E6700 with speedstep enabled. And works no problem at all with my current overclock. Can tell no difference in performance, so speedstep stays on for me.
