AMD XP2500+ Barton AQXEA

Post by exxowire » Wed Mar 17, 2004 9:11 pm

Anyone know how to overclock this CPU up to 2332.5 MHz ? :?:

I tried to overclock with my abit NF7-S rev2.0 from bios and the max. core speed I coud get is 2004.5 with the external clock set to 200, 10.0x multiplier, agp 66, cpu ratio 6/6, core volatge set to 1.525 v and the memory timing is set to 6-3-3-2.0

Thanks :D

Need Help... anyone know how to set the bios to overclock my abit NF7-S so that I could get the max core speed 2332.5 MHz ?

thanks

Exxowire,

I think you should ask another website dedicated to overclocking. They will know *much* more than we do, and will be able to provide you with better solutions.

That said -- I have managed to push my Barton xp2500+ to 2200 MHz using a Vcore of 1.825, FSB 200 MHz. Memory timings were stock (I don't know), ratio was 4/4 (=6/6). It got fairly warm though, and keeping it cool quickly became noisy, so I de-clocked it back to 2000 MHz. I'm much happier now!

Good luck in finding a good overclocker's forum.

Thanks a lot Pjotor

Yes you were right about getting warm... although I used Thermalright SLK 900 (A) to cool the cpu down the panaflo fan went noisy.

Anyone know any good english language overclockers forum ?

Pjotor,

What type of heatsink do you use to cool your Barton xp2500+? How about the temperature after you clocked it back to 2000 MHz ?. Did you test your Barton with CPU-Z software ?

I used a Zalman CNPS-7000AlCu. At idle and 2200 MHz, the temp was 48 C at idle and 55-60 at load (using CPUBurn). I could lower the temperatures by cranking up the fan, but it became too noisy.

Clocking it back to 2000 MHz and 1.625 V, the temps are 40 C at idle and 48-50 C at load using CPUBurn. These temps are achieved with the heatsink fan on its lowest setting with a Zalman fan controller, which is around 5 V. If I go over 8-9 V the fan starts to bother me.

That said, I could probably get much higher clock speeds with the same setup, if I wasn't noise conscious.

Prime95 torture test was used for testing stability.

My Barton is an AQYHA.
I get 222x11 = 2442 MHz (it's locked...) at 1,65 V on my crappy ASUS A7V600-X. Used Prime95 without problems. Using a Zalman CNPS-7000AlCu and 400 MHz RAM.

If you look at Overclockers database, it looks like you might be able to do more.... if you're lucky!

It depends a lot on what you want to achieve.
If you just want the CPU to run really fast you should lower the FSB a lot and increase the multiplier instead. Depending on what you use the computer for this might not increase your overall system performance.

In general the higher vcore you use the faster you can clock your CPU, but you also increase CPU temp a lot...so that means lots of more noise to cool the CPU.

Your motherboard/RAM etc is often the most limiting factor for your FSB.
The heat generated from your CPU as you turn up MHz and vcore is often the most limiting factor for your CPU speed.

Your current settings 10.0*200 @1.525 vcore is probably one of the better tradeoffs you will find.

Here is a great forum for ABIT Boards. Also has an OC section and a NVidia section.
http://forum.abit-usa.com/

I also have an NFS-7 running a 2500+. I have not attempted any OC yet.

I run too warm now. The Zalman CNPS-6000-Cu doesn't cut the mustard. I run about 50C with case temps about 32C. I was going to see if I could lower the case temps before going out and getting a different cooling solution.

Good luck with your OC. I just started messing with my old KT7A. Managed to hang it completly! Made a stupid FSB setting. :wink:
Cleared the CMOS and when I stated back up Windows ME thought I had new hardware and broke itself during the installation. Looks like I will be doing an OS reload.

At idle? I had 56 degrees (2500+, bad caseflow) at idle but lowered it to 42 by activating S2K bus disconnect. This is a great feature!!!!
In BIOS(for NF7-S), go to "Advanced Chipset Features" and enable "CPU Disconnect Function", if you haven't done it.

Read more about it here, look for "S2K" under "Heat dissipation".


Good luck!
