I posted this in overclocking but couldnt get a reply..

Here is the problem, Im having a problem with Turbo Boost...

When I change the multiplier and boot to windows it remains at whatever is set and doesnt turn off to the standard 1.6GHz, when I reset the BIOS to standard clock the Turbo Boost seems to work again? What the deuce?


Any light shed would be much appreciated, thanks guys.

Also to add, something is defiantly wrong as...

I have it standard and when turbo is activated it jumps to 3.5GHz and not what it is set to as turboed at 3.8GHz??

iirc, turbo occurs at load. The higher the load the higher the clock speed?

Try running Prime95 in the background and monitor what you boost up to

Yeah, when I up the GHz it stays on constantly and never drops, so stays at load constantly.

When it is standard it idles at 1.6GHz and jumps under load through prime95 or such to 3.5GHz (which is still strange as it should turbo up to 3.8GHz).

Any ideas Cookeh?

Turbo mode doesn't mean it's always on.

You probs have SpeedStep on (which slows down clock speed and volts when it's not being used or idling to save energy) which accounts for the drop in speed.

As for not going to 3.8GHz I'm not entirely sure. Is your CPU at 100% load when using prime95?

Yeah, thats what I want is speed step but when I try and OC it doesnt work, stays at max with out stepping down to 1.6GHz

Yeah thats under full load and is at 3.5GHz.

The reason I think something is up is my old pre B3 board had speedstep and also when standard boosted to 3.8GHz, but what I dont want is to clock to 4.2-4.4GHz and have speedstep off as it is wasting like you say.


RTJ
 
I take it you have SandyBridge then?

Leave SpeedStep on and overclock it normally (assuming you have K series) - Speedstep should still work perfectly.

What specs do you have?
 
Hmmm, I also assume you're using CPU-Z to detect CPU speeds?

TBH, unless someone else comes up with any other ideas I'd just clock it and leave it (just put PC into sleep mode when you're not actively using it to save energy that way :p)
 
Cheers for the help Cookeh.

Should I RMA it and ask for a new board, as the old one like I said before B3 was fine in that respect?


RTJ
 
Hmm, I dunno actually. Might be worth waiting and see if anyone else has an opinion :)

Could be an issue with the B3 chipset itself, but RMAing it is certainly an option!
 
Have you changed any of the power saving options?

the C states in the BIOS control the reduction of the multiplier and the voltage when you aren't requiring the extra speed.

What board do you have?

Its the Asus P8P67 B3 Motherboard.

Can you point me out how to change these setting so that it works like you state please?

OK That's good as i have the same one (just not the B3 variant)

I'm not on that PC at the moment so found this.

In the bios on the advanced tab, in the CPU configuration you need to check the C1E, C3 and C6 settings.

Note what these are and change them to enabled if they aren't already.

Kris - is this any good...

I activated turbo boost, saved it then rebooted to BIOS, then I changed the auto clocking software to a few custom tweaks as 4.2GHz and the Bus speed to 100 dead on and since then now booting....

It idles at 1.6GHz and then steps up to 4.2GHz when under load, so its working now, does that sound ok, even though it is the auto boost that has been tweaked with a few settings?


RTJ
 
So you've got all the benefits of speedstep but an overclock to 4.2 when under load.

Sounds ideal to me :)

I would run prime95 now to confirm things are stable. Then you can decide if you are happy or want to continue on. You may be able to get to 4.7 but this normally needs additional voltage and good cooling. 4.2-4.3 is a reasonably sensible level for an overclock if you ask me.
 
Cheers dude. Yeah gonna run intel burn test. I have the H50 with push / pull but thought that I dont wanna over do it. Cheers again, also to you Cookeh.
