 Thread : Speedstep on Core Duo 2
 
Profile: member
More Information

I just got myself an Intel CPU, having changed from Athlon64. The latter had very good tools, by means of using "minimal power settings" to make the CPU run at lower clock speeds during idle periods. I can't see how to achieve this with the Core Duo 2. CPUz always reports it running at full speed, so does System Info.
Help much apreciated!

It looks like you might need a BIOS update. This may help

While the numbers of problems reported seem vast, it has been our experience that most P965 motherboards had similar amounts of issues upon release. Most of these have been solved through BIOS updates, driver releases, or revised board designs. abit has already solved a number of problems with the last two beta BIOS releases and are well on their way to solving the final issues that also include getting EIST, TM2, and C1E operating correctly again in the next production release BIOS.

EIST is enable in BIOS, and it is the latest BIOS version (v21)...

I could be wrong, but I don't think windows has any control over EIST. Nothing on the Abit forum?

It appears that the EIST problem was fixed in this version. I don't know what else to tell you.

http://www.abit.com.tw/page/en/mot [...] DINFO=BIOS
BIOS ID:11
1. Enhanced overclocking ability.
2. Modify the Voltage adjusting function.
3. Fixed an issue that the system hangs during Vista installation, when using a Kentsfield CPU.
4. Fixed an issue where the system sometimes hangs on POST code 2A.
5. Fixed the JMB363 performance issue.
6. JMB363 now works as intended when enabling ICH8R RAID ROM.
7. The "EIST adjusting" function now works as intended.
8. BIOS compiled date: 3/27/2007

I've now played around with the power settings under Vista a little, and changed it from "Balanced" to "Power saver". Then clock speeds dropped from 3000 to around 2000, which is still way more than I need/want, no?

Check CPU-Z for the multiplier, I'm not sure about yours but the Q6600 drops from 9 to 6. As a matter of fact, my 3G OC drops to 2G. so your probably good.

Apparently, I was in left field.

 

Enhanced Intel SpeedStep® Technology How To Document

 
Quote :

4. Finally Enhanced Intel SpeedStep technology must be turned on in the OS. Currently, for Windows* XP SP2 operating systems Enhanced Intel SpeedStep technology by default is off. To turn it on do the following:

 

* Under Control Panel %u2013 open Power Options
o Under the Power Schemes pull down menu
+ To turn Enhanced Intel SpeedStep technology ON select, "Minimal Power Management", power scheme.
+ To turn Enhanced Intel SpeedStep technology OFF select, "Always On", power scheme.

 

To verify that Enhanced Intel SpeedStep technology is enabled do the following:

 

I never use always on, because I shut down the monitor and the HD after about 30 min. I never use Hibernate or suspend though, too many problems with it.

I'm actually using Vista, so the System screen looks different. But even though CPUz reports 2000MHz, System reports 3.06Ghz. But it doesn't get updated there, so it might be a spike of CPU activity from loading the screen?
Multiplier is indeed 6.

I would rely on CPU-Z. I've seen, and I can't remember exactly where, the OS reports one number and CPU-Z reports another. The CPU-Z number increases as you load the system.

You can run Prime95 25.4 with CPU-Z open and see the Multi change. Don't run it very long without a temp sensor running, or you could make the CPU quite hot if you don't have proper cooling.

How cool is that!

How about using the power button?
You can't get any greener than shutting the machine off!...lol

Look, if you need it on 24/7 then don't worry about it. If not shut it down when you're away....screwing with it, you'll wind up having to re-install or worse mucking up your system !!!!!!!!!

You can always set up your power options to shut down all the system components when you want.

Hope this helps!

Weird, on Vista with balanced scheme, EIST works fine over here on a C2D E4300, no need to use Power Saver.
