The real big difference in "Athlon64 v AthlonXP" is the SSE2 instructions that the a64 uses over the xp. Just Check my profile, i have a Athlonxp @2gh and a A64 @1.8ghz. big difference in crunch times, fyi- both are using optimised clients for there respectable capabilities. Just for s@#t and giggles, check my dualcore thate i just got, its just a beast.

Lord T - I have an A64 3500 running Windows 2003 Standard Server and an optimized client. Work Units are taking on average 1 hr 14 minutes to complete.

The machine is not overclocked and runs 24x7 as a small home file server. Your mileage may vary.

OK,point me in the direction of a compatible optimized client, Lord T.

Go here for TMR's optimized clients. Download and run CPUZ first, and get the file for your CPU's instruction set. Happy crunching...

Hi Lord T,

in this thread the C&Q issue has been discussed. If you run WinXP, you can find the C&Q settings here:

Start>Settings>Control Panel>Performance and Maintenance>Power Options.

The question may have been answered but unfortunately it would seem that my mobo - Gigabyte GA-K8NSC-939 does not support this feature. The (ctrl+F1)bios has no refernece to Cool'n'Quiet and I have updated to the latest BIOS. There is no reference either in the systems/power options, AMD web site offers onle an exe for w2k not xp.

---

the only thing I found was a refernce to CPU-Thermal Throtle, this was set to 50%. Is lower or higher better?

I'm not positive but my guess is that CPU-Thermal Throtle is the same as Cool'n'Quiet. This is what needs to be ajusted or turned off.

I have not disabled this feature but have tried both lower and higher numbers and the result remains the same, will disable and see what happens. Lord T

Have disabled this feature but the processor is still throtling back to 15-20% and running at 1GHz

Hi!

Cool'n'quiet and thermal throttling are two different features.
Thermal throttling gets activated if the cpu runs too hot,
cool'n'quiet if the system is idle.

You could try increasing the priority of the running seti tasks with "task manager"

If this helps, cool'n'quiet is the culprit.

I remember seeing different cpu speeds listed somewhere under "frequency & voltage control" in my bios.
Maybe something can be disabled there...

Regards Hans

Re-enabled Thermal Throtle,changing priority with task manager does not work either, can't find anything under 'voltage control'

---

Checking the process priority I have noticed that System Idle is taking the remaining processor power

Hi!

You have to change the view from applications to processes in task manager,
than right-click on a process.

This should give you a context menu containing a "Change Priority" option.
Just set to "normal".

BTW NEVER set a process to "real time" or your system might lock up!

Yes, Ive have tried those options and the processor still throtles back. Lord T

Pentium 4 Thermal Throttle

Introduction

Pentium 4 processors have a feature called Thermal Throttling which protects the CPU from overheating, preventing it from burning. Case the processor reaches a "trigger" temperature (which varies acordingly to the CPU model), the processor automatically lowers its speed, in order to make the generated heat to decrease. In the event of an overheating condition, your PC will be slower, but on the other hand your processor won't burn. If even lowering the processor speed the temperature doesn't drop to a safe level, the computer is turned off, in order to protect your CPU.

Actually there are two types of Thermal Throttling:

* TM1: Available in Pentium 4, Xeon, Celeron (Northwood and Prescott cores only) and Pentium M processors. In this type the Thermal Throttling function does not physically lower the CPU clock, but it inserts idle cycles between the instructions sent to the CPU core (i.e. it inserts wait states inside the processor), which lowers the processor performance, hence its temperature.
* TM2: Used on socket 775 Pentium 4 and Celeron and Pentium M processors, this type really lowers the CPU clock. This is done by lowering the CPU clock multiplier.

Average users won't know if the Thermal Throttling is activated or not in their computers. If this feature is activated in your PC, it will run slower and also this means that you have an overheating problem in your computer, which has to be solved.

There is a very small program called Throttle Watch (http://www.panopsys.com/throttlewatch.htm) that can tell you if the Thermal Throttling is being activated or not. Just uncompress and run the program and you will see two windows. The top window shows how much the processor is being used. You can access a similar windows by pressing the Control Alt Del keys at the same time on Windows XP and then selecting the Performance tab.

But it is on the lower window that you will find the advantage of this program. This window shows if the Thermal Throttling feature is being used or not, and how much.

Oh dear!

This is the moment where I usually say: Wait a minute I'm coming over to have a look!

So I'll have to give up now I'm afraid.

You might try running Sandra Lite

to see if your system has a performance problem.

in my last post you will notice it says :

You could use this one http://www.amd.com/us-en/assets/content_type/utilities/power.exe

to see if your cpu runs at full load.
