cpu speed is low(turbo not working properly)

my m11xr2 used to work fine until today, I notice its performance become significant lower.

and I checked the cpu-z and hardware monitor, the multiplier is only up tp X 11 so that the highest frequncy is down to 1.4Ghz now, from the supposed 2.2Ghz. and most time it doesnt even turbo at all, leave the pc running quite slow when I open any demanding program.

the temp is totally normal so I dont know the problem is.

Please help, thanks!

 

Use Throttlestop, search the 'supercharge your M11xR2' thread

 

@Mercy - what is your power setting? If it's anything other than high power, you might want to change it to high power to see if that helps.

 

Thanks for the replys.

I am using high power settings.

tried Throttlestop, seems working, more feedback later.

 

When these processors are fully loaded they will throttle by design once they exceed a temperature threshold. If you happen to be overclocking then what you'll see if an actual decrease in performance compared to not being overclocked. Nice, huh?

ThrottleStop fixes that situation by providing us a means of raising the thermal limits and thereby preventing the throttling. The increase in performance is significant in quite a few types of applications including more stable frame rates for most games (not higher FPS, but better average FPS) and in CPU bound games a slight increase in the max FPS achievable.

There's no negative impact to these limits being raised either. Yes, battery life will be shortened, but most sitations who cares. CPU intensive applications aren't meant to be run on battery. Temperatures remain well within Intel's spec. Dell could very easily have provided a BIOS level setting that accomplishes what ThrottleStop does in a much more efficient way. ThrottleStop is basically having to argue with our BIOS to maintain these limits. It does a great job at it too, but it could have been so much easier if they'd simply taken the time to implement overclocking properly for these processors.

 

Sounds like something Dell should implement into the R3.

 

mercykiller: Your problem almost sounds like clock modulation throttling got accidentally turned on. ThrottleStop can monitor for and correct that problem. If you have any further issues, post a ThrottleStop log file. By default, ThrottleStop turns off the crazy throttling schemes that Dell likes to use so just starting ThrottleStop might have been enough to get everything working correctly for you again.
