How to OC a unlocked Athlon XP in a NVidia 2 chipset mobo

[adriano09]

Is there any way to OC by multipl. a unlocked Athlon XP 2900+ (unlocked to Mobile Athlon XP-M) in a Nvidia 2 chipset MoBo (Abit AN7)??

I mean, I change the multiplier (default, for this CPU, is 10x) to 10.5 or 11x but nothing happens....

Is there any way to get it working? Does anyone know if Pinmod works with Nvidia 2 ultra chipset mobos??

Thanks a lot!

Ok ,thanks, but that shows how to OC by changing the FSB speed. I do that.... I would like to know if it is possible to OC in a Nvidia 2 chipset MOBO (like my AN7) by changing the CPU multiplier in a unlocked Athlon XP.

 

[adriano09]

...no... i can´t change the cpu multiplier, because there is no effect at all...i mean...if i change the FSB i get OC, but when i change the multiplier nothing happens.

I´ve read that this is happening because my mobo is Nvidia 2 chipset-based and it seems that this chipset has this bug, that don´t allow the multiplier change in a UNLOCKED XP, just to original MOBILE XPs....

... it sucks.... so, i´m asking if someone knows a way to bypass this bug or if the pinmod works with this mobo.

thanks again

I'm not aware of any such "bug" in nForce2 chipsets.

I've got an XP Mobile in an Abit NF7, also an nForce2 board, and it allows me to adjust the multiplier. Try some different bus speed and multiplier combinations and then check it with CPU-Z to see what's happening. Make sure you look over all the BIOS settings to make sure you're not missing a setting that may be overriding your manual changes.

Also, check to see if there is a later BIOS for your board. The XP Mobile probably won't ever be a recognized chip, but a later BIOS may fix your problems and allow you to make these adjustments.

...as i said, to ORIGINAL MOBILE XPs the multiplier changing works fine.... but when you try to change it in UNLOCKED ATHLON XPs (with the 3rd L5 bridge unlocked) nothing happens in Nvidia 2 chipset mobos.

Oh... now I see you have a superlocked XP modded to XP-M.
You'll have to change the multiplier through software under Windows. Google it.

yeah, but unfortunely, that doesn´t work with Nvidia 2 chipset mobo either... this mobos does have the option to change ON THE FLY, but it doesn´t work..... when you try to change under Windows, the PC freezes, every single time and in every nvidia 2 chipset-based mobo i´ve tried.

...so, has anyone tried pinmod with any of these kind of mobos?
Thanks

With a super locked Barton, there are not any mods to adjust the multipler.
FSB is your only way. The pinmod will not work either. I bought a moblie Barton
for this very reason.

Why do you want to raise the multiplier instead of the FSB? Your system will perform better at the same CPU frequency with a higher FSB (ex: 2.00 ghz with 200 FSB is faster than 2.00 GHZ with 333 FSB)

For 2 mains reasons:

- My cpu default FSB is already 400Mhz (10x200 = 2.0 Ghz)
- By Ocing FSB you OC your whole system too (CPU, RAM mems, PCI and AGP cards etc...), and OCing by multiplier you OC only your CPU.

There is another reason, wich is that by FSB i can only reach stability as far as 424-426 MHZ ( wich gives me a 2.11 or 2.13 CPU), and i think that with multiplier change i would be able to get more from my CPU but remain stable.

Thanks to everyone who´s trying to help!

Oh ... ok them... that sucks big time.....
Thanks a lot.

The only thing that would hold you back when clocking by FSB is you RAM.
Both PCI and AGP can be locked by setting AGP to 66Mhz in BIOS.

You need to have a pair of RAM that can take at least 240Mhz.
Something like OCZ VX PC3200(BH-5), Corsair 3200XL(TCCD) or Crucial Ballistix PC3200 will get you that speed.

yeah...and i know that.. :-( my RAM is Crucial but it´s not Ballistix.....

Good news is that last night i did some changes in my configs and i could reach 430 FSB. I´ll try some more configs to see how far can i go with my ram.
