I currently run to systems, a 3500+ Athlon64 and a 2800+ Athlon XP. what is the best way to configure the A64 so that it outperforms the XP, at the moment the XP seems consistantly better that the 64?

---

I've had a look at the information available on the computers, and feel more information is needed.

what is the true cpu clock speed, depending on exact models clock speed of XP could be higher than 3500+ ?

What mobo's are in use?

How much memory is fitted and the clk speed's of same?

Does the BIOS allow adjusment of memory timings?

That's my first quick pass. I have seen reports that 32 bit progs on 32 bit cpu's are faster than 32 or 64 progs on 64 bit cpu's mainly because the infrastructure needed to compile 64 bit programs and OS is not there yet.

Athlon64 :- CPU 200MHz, 1.5GB RAM, Gigabyte GA-K8NSC-939. AthlonXP :- CPU 166MHz, 512MB RAM, DFI Infinity NFII Ultra. Both with unoptimized settings :(

What else is running on the Athlon64 system?

32 bit programmes do run faster under a 32bit OS.
However even without a 64bit OS & applications many 32bit programmes are often faster than clock speed alone would suggest on a 64bit CPU due to it's extra registers, and also there have been quite a few tweaks to the micro-code as well with each version as they've been released.

You should take a look at the Cool'n'Quiet settings in your bios on the athlon64.
Try to disable it and see what happens to the crunching times.

Winbar?
Bring up the task manager & see what's using the CPU time, otherwise use performance monitor to log things over a day or 2.

Just did a quick check.
Athlon64 3500+ 2.2GHz
Athlon XP 2800+ 2.08GHz or 2.25GHz depending on the type (Thoroughbred or Barton).

The 1.5GByte ram is unusual size can you tell us how many sticks and were they all installed at same time. Do you know if they support the same memory timings, the BIOS by default will set to the lowest SPD timing if not the same.

Andy

Will watch for a couple of days, will try the cool'n'quiet settings and the XP is a Barton core

1.5GB Ram is x3 stcks of 512MB DDR 400 (same speed etc.)

By using 3 memory sticks you've disabled dual-channel mode on the memory which will slow the system somewhat but the most likely culprit is the already mentioned Cool'n'Quiet feature. I'd disable it.

I agree with this, but if it is the Cool'n'Quiet then think it needs investigating why its slowing the cpu. Even running at 100% using stock heatsink/fan shouldn't cause overheating.

Andy

yeah, i think it has to be a setting somewhere. I have a AMD 64 3000(1.8 Ghz) that before i optimized it still went a little faster than my frineds XP 3200(at least 2 Ghz). Now i overclock and run optimized and it takes anywhere from 1 to 1.33 hours for a WU, which is almost twice as fast as his XP 3200 optimized. Just for reference to prove that it should be going faster than the XP machine.

Join the team, SETI.USA We are growing and could use your help to overcome SETI.Germany...www.setiusa.net

And use optmized clients, it can greatly speed up crunching on athlon64 because of SSE2 instructions that AthlonXP lack.

Have removed x1 stick of Ram thus enabling Dual Channel, but can't find anything to do with cool'n'quiet

On a Gigabyte MB, it's probably in Setup... I know it is on my ASUS, and they're direct competitors, so probably do about the same things. No telling what they call it - I had to actually read my MB manual!

Have checked through the BIOS and Manual and can find no reference to Cool'n'Quiet

With a Gigabyte Mainboard you have to enable the extended view of BIOS by pressing CTRL+F1 in the main screen of the BIOS.
Then go to the new appeared "Advanced Chipset Features" and you will find the Cool'n'Quiet option.

The biggest bug is sitting 10 inch in front of the screen.

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