unlocking week 39+ athlons

I´ve found something.
Explained here:

Well done..

Thanks for sharing hopefully the guys here can continue your efforts.

Posted this on OCAU for you Eversor :)

Tks bravo.
Please forward this, as i´m not registered in many forums.
Only here and ocworkbench.

Very interesting, will post links as well!

YAY!!!
You have just gained my eternal (or until i forget anyway) gratitude!
Thankyou.

Careful, someonde posted it´s nForce 2 IGP wasn´t working with P-State changing...
I think most SiSs will have no problem tough...

This thread explaines what to do in case it doesn´t works with some mobos...

Tks to the guy who wrote it, couldn´t have done it without that info.

nice find but still can't get over 2500+ at 166 mhz bus and 3200+ at 200fsb via multi adjustments

edit
nevermind I read about the L6 cutting

so who's gonna try it :O

so this shows how to unlock the really locked chips?

Glad someone else found the cpuheat link. I saw it at work last week but got sidetracked by a customer and forgot about it.

Off to PM saaya, thanks! :D

I'll give this a shot on my duron... worth a try.

:confused: i thought the mobile mod doesnt work either? thats what people over at ocforums posted.

Remember this thread where my friend Marty posted link to my webpages? At that time we didn't know it works for SiS chipsets. And also for locked CPUs! I expected it won't work but hasn't tested it. Someone did yesterday at OCWorkBench.

Eversor and Petr

welcome to the sickness!!!

i might try it on my duron, but not till after i mod the L2 cache and oc it like a bat outta hell

My nforce 2 didn´t accepted mult change in windows, and is booting at default, tough cpu MSR did detect it as a mobile part, and a max mult of 12x, as set by L6 bridges.
Gona try to find the registers to change to enable p-states changes.
If someone does find them please post.

Tks Petr for that awsome software, and all the documentation you put in your website.
Was trying to found who did it to thank i´m, after all you did all the work.

Do you think it´s possible to implement this in bios?

nForce 2 does not support FID_Change command or has it disabled. I hope for the second reason.

Yes, I did majority of work. I searched for MP mod then looked for Mobile mod. I made a bet on second from right on L5 when I found at Fab51 I was true. Discovering L6 and L8 meaning with my program on hand and knowledge of PowerNow! was quite easy then. But I have to thank Fab51, Andy (alias honey X) from Rebels Haven and of course you for testing on different hardware.

Sure it would be possible to implement it in BIOS. Motherboards that load Windows with L6 settings (not L3) already do change multiplier on-the-fly during initialization. CPU always starts with L3 settings then some BIOSes change to L6 settings and some don't. It would be quite easy for motherboard manufactures to implement "PowerNow! Multiplier" ability to BIOS. It would require mobile CPU, of course.

It worked with me on a Nforce2 mobo in windows but I used: CrystalCPUID 2.5.1.39A at http://crystalmark.info/?lang=en
But: I've an original 2500 XP Barton mobile and it's a week 36.

Good news then, if one nforce 2 works than all should be able to.
If you can send me a screenshot of your motherboard registers configuration in WPCREDIT, so I can see if I find the FID_Command bit.

BTW Petr you don´t know of any PCR file for nforce 2?

It is surprise to me it is possible with CrystalCPUID. This program should use exactly the same way to change multiplier as my program. It must be his nForce 2 is set somehow different.

No, I do not have nForce 2 PCR nor do I have datasheet :-(. It is confidental.

Petr:

I couldn´t find where we can see if our motherboard as FID_command activated or not in HWINFO32.
Where and what do you refer to?

I have it under Bus - PCI Bus #0 - VIA VT8377 KT400A/KT600 Chipset - System Controller. It's name is FID Command Detect. It was similar for VIA KT333. Maybe HWiNFO lists such information for nForce 2 also (I don't know, didn't looked when I had nForce 2 half a year ago).

§§§§!
SiS 748 and nForce 2 don´t show anything like that...

If someone can change mult in windows with an nforce 2, please post an WPCREDIT image of Host Bridge settings to see if we can find the right bit.
