I have my 2700K running at 4.8GHz, but was wondering how to stop it from throttling down to 1.6GHz when not in use? I've tried disabling Speedstep, C1E, EIST in my BIOS (Maximus IV Extreme - P67) but that hasn't stopped it.

 

Thanks.

Disable C3 & C6 report too

Thanks for the quick reply. All that stuff is disabled. The only things I have enabled are Intel's Adaptive Thermal Monitor and Execute Disable Bit and I have Package C State Limit to "No Limit", the other option is C6. BTW, CPU-Z does show my CPU at 4.8GHz, but T-Monitor shows it at 1.6GHz until I start up something demanding.

Honestly, why would you care about the CPU throttling down during no load? It saves the CPUs lifespan from the high OC voltage, and it makes it run cool while not in heavy usage.

Why would you want to?

Because I am testing certain things. I've already eliminated the majority of stutters in FSX by disabling certain CPU throttling. FSX is badly coded, and having been watching T-Monitor while running FSX it seems the CPU cores don't know whether they're coming or going in regards to load when it comes to FSX.

Just dropT-Monitor and trust CPU-Z. It's not really throttling

Do you have Hyperthreading enabled - you sometimes see this effect if you do.

Use CPU-Z to monitor core-speed. Within FSX, I have NEVER seen my core-speed drop from 4800MHZ.

CPU-Z never reported my core clock dropping from the overclock within FSX either - yet disabling the throttling gave me a performance boost and cured stutters.

I find this hard to believe honestly...

I don't think so. No stuttering here. What you are suggesting is a great way to needlessly wear out your cpu without any FSX benefit whatsoever, and bad advice to others if followed.

 

Kind regards,

Fair enough, but it's fairly easy for me to see that it is indeed the case. All I have to do is enable the throttling, and the periodic 2 second stutter returns.

For all you know my CPU is running on the same voltage that 95% of Sandybridge processors are currently running at, what with Auto typically overvolting - besides, there's no evidence of additional wear below 1.375v.

What you want to disable is C1E. Mine went to 1.6 and it did cause issues with FSX (stutters), and also for BF3. BF3 for some reason wouldn't make the CPU increase to normal freq when it loaded and load times were nuts...

To disable throttling disable Speedstep, C1E, C3 and C6. This is however not recommended, as Stephen said, and I also find it to be a very bad practice, except for testing. But certainly doesn't cause stutters, for as soon FSX starts, CPU goes to full speed and never throttles down, until you close the FSX.

 

Not throttling will cause a high wear on the CPU on high overclocks and will most likely seriously lower the life expectancy of the SB chip.
