Vista not too sure about CPU speed...

[The Jambo]

Vista reports 2.40Ghz CPU running at 3.73...

CPU registers the correct speeds, as does Crystal CPUID.

Any reason why Vista doesnt like it? anyone seen anything like this before?

(please excuse the terrible timings)

Turn off C1E and Speedstepping in your BIOS

Speed Step throttles. It doesnt increase speed for you.

Vista is just reporting the default CPU speed.

Speedstep does not appear to be running in that shot, or CPU-Z would likely be reporting a reduced speed as well.

I'm not sure what the 3.73Ghz is, looks like it could be some equivalent performance rating, but I'm not currently using Vista, so cannot confirm.

I know what Speedstep does, and I've sorted the problem the OP is having before by turning C1E and speedstepping off.

Am I the only one confused by what you're asking? Looking at your screendump it seems that you have overclocked the cpu, that's all

the stock Q6600 runs at 266.66' x 9
yours is running at 415 x8 which gives you a 38&#37; overclock. If you want it to run at stock speed then... stop overclocking it?

Or do you mean that Vista is reporting it as 2.4, when you think it should report 3.3? In my experience Vista reports the stock speed, for instance my E6850 shows as 3Ghz, rather than the 3.2Ghz I run it at.

The OP is just wondering why Vista is reporting his CPU speed as slower than it actually is.

Indeed - I've seen this issue too. Speedstep is showing as what's active in Crystal.
It often screws with Vistas readings in my experience

The Vista rating part is showing 3.73Ghz.

The Vista rating part is showing 3.73Ghz.

My bad, didn't make myself clear...

"Q6600@ 2.40Ghz" I believe this rating is taking from the CPU namestring, with the actual speed shown after.

That said, I just read the original post again 4 times and realise my schoolboy error - Vista is reporting 3.73Ghz rather than 3.3Ghz which is the actual speed, right? In which case... dunno

I wouldnt mind a Q6600 thats has a defalt 3.7ghz speed.

Just realised, vista is reporting what the speed would be if i were using a x9 multiplier.

415x8 = 3320
415x9 = 3735



Another question out there, Ive heard the Q6600 CAN reach speeds of 3735, so why when i change the multiplier back to 9, does it fail?

Voltages are at 1.38 when i try it , and since its the multiplier, its only the CPU that has the effect, surely?

All CPUs are not built the same. Just because some Q6600s can reach those speeds doesn't mean that yours will.

Even if yours could you'd probably need to up the voltage and use some quite heafty cooling.

The vista performance rating thing isn't very good at keeping track of changes to the computer including clockspeed in my experience. Have you ever had yor chip at 3.73ghz? If so thats probably it.

If not ignore it, your PC seems stable and apart from deciding if you can run aero when you first install the performance rating doesn't really do much and isn't the best benchmark. Clock the nads off it and you wont it any higher than 5.9(current max, MS increase the limit periodically as new hardware is released iirc).
