AMD 2200 T-bred Unlock UPDATE !!!

**deerhunter** · 06-30-2002, 03:58 PM

Tested the rumor that you ONLY need to connect ONE bridge to unlock the 2200.
The rumor is true, the rumor is true.

I connected only the 5th bridge on L3 and have ALL multipliers from 12.5 downward!!!

**deerhunter** · 06-30-2002, 04:19 PM

You DON'T even have to fill the pit!!!!
Just conduct/paint a bridge around it!!!!!!!!
Yes

Now if your CPU dies it is a lot easier to remove the paint gently and no one will probably notice, therefore your warranty is a little more secure!

omg that is sweet! Very sweet!

**Sayajin** · 06-30-2002, 05:02 PM

thats kool.....
man amd really made it easy this time didnt they..
i love AMD! ehheh

**MrIcee** · 06-30-2002, 05:18 PM

Excellent news Deerhunter indeed

What did the KX7 boot up as on the first boot?? I'm just curious...as Frank's method just turned it into a 1700+ and an 11x multiplier. Let me know

**deerhunter** · 06-30-2002, 05:26 PM

It booted at multiplier 5.5!
5.5 X 100 = 550 MHz
Hey Ran, did you ever get a chance to try the older BIOS and verify stability increase, if any as Opp indicated?
edited - Never mind I tested the old BIOS, bmarks & stability are better with latest BIOS, as it should be!

GJ DeerHunter! We've been discussing just the Hi/Lo bit bridge.

Well done, good to know you can just paint around the bridge

. Well done.

**Brothernod** · 06-30-2002, 06:50 PM

Can anyone else verify this??

Weirder things have happened than just one person getting a lucky cpu.

**sysfailur** · 06-30-2002, 07:02 PM

When I get my new Tbred I'll give it a shot.

**candjac** · 06-30-2002, 07:41 PM

Brothermod et al,

It's not a lucky cpu, it's the same kind of a "workaround" a bios that's not able to reset the Enabled HI 8X Bit Value to LO that pcstats.com discovered when they reversed the Palomino L10 bridge pair from open/closed to closed/open to Enable 5X thru 12.5X Multipliers on Palomino. The rightmost Tbred L3 controls its 8X Bit Value the same way the Palomino L10 "pair" controlled its
8X.
http://www.beachlink.com/candjac/index.htm link to Tbred and palomino decoding articles to understand circuits.

But basically the L10 "pair" simulates a 3pin/jumper set, while the singlr L3 simulates a 2pin/jumper set...both can set/reset HI/LO signals.

Kinda nice smiley face!

Sounds excellent. Do you think you could post exact directions on how to do this for those of us who have no clue. Eheh. I've never done any modding or unlocking of any sort.... so I have no clue as to how this works or what I have to do... I should be getting a 2200+ soon w/ a KX7-333R so I'm gonna need to do this...

All you need to do is buy a conductive pen and do what is pictured. Just don't get any conductive pen in the little cut line.

**Svenn** · 06-30-2002, 11:55 PM

Well, how does a conductive pen work? I'm a total newb when it comes to this....

Had to post at 5.5X if it was going to post at all, here's why. Default Tbred 2200 = 13.5X Remapped from 10.5X Enabled /Set HI = .5X + 2X + 8X Bit Value bridges open. Closing the 8X bridge leaves just the .5X + 2X bridges open/HI Enabling 2.5X which Remaps to 5.5X.

When Frank closed all L3 bridges so that all were then = LO, total Enabled/HI = 0X which remaps to 11X, which he got.

The Remapping Algorithms and Bit Values are at
http://www.beachlink.com/candjac/index.htm link to Tbred or Palomino decoding articles. Knowing the Bit Values for each bridge and the Remapping Algorithms lets one easily decode what will happen when the L3 bridges' open/closed pattern changes...not as easily done with just Table of open/closed settings.

Thanks candjac for the confirmation link!
Although ocing is an art, I doubt many of us could spell Algorithm!
If I was a mod I'd make this a sticky.
I think I can finally see the light!

We care! It,s done. What Light?

Thank you for joining Xtreme and sharing the wealth.

Deerhunter and Hardass,
Credit to Deerhunter and xtremesystems.org + links + pic of the 1 L3 mod by Deerhunter at
http://www.beachlink.com/candjac/index.htm link to Tbred decoding article...might be a few hours as ISP accidently locked us out of our .htm folders, but says he's working on it....keep trying.

We always credit, this is not an ego trip and we are not alone, help always needed, welcome and appreciated. In fact we're still running a K6-3+ 450 at 616Mhz. Do the decoding from early pics, get confirmation from various correspondents on the web like Deer hunter. Then sometimes buy a chip and confirm with multimeter tracing of circuits connected to socket pins and bridges, ground pins and Vcore pins. Then give the chip away to family. May build a Clawhammer system this fall.

Thanks to all, John C.

**xgman** · 07-01-2002, 06:41 AM

This new method makes it really easy to clean up if an RMA is necessary! Will this new method work on the 2400+ do ya think?

N8 · 07-01-2002, 07:00 AM

The new method has me almost wanting a Tbred, xgman

You are right.....much easier to clean up if RMA is needed

**candjac** · 07-01-2002, 07:08 AM

All else equal...it should, meaning if inability of mobo/bios to reset the 8X Bit Value from HI to LO is the "only" problem. And we know that higher speed Tbreds will continue to have 8X Bit Value HI, 5th L3 bridge open. But consider also that at some point 12.5X max Multiplier may not be enough, ie, might need 13X. Then need to have bios set 5X with 5th L3 "open", ( IF system posts at all with open L3),...gets a bit messy and wonder what happens to system timings??

**2xD** · 07-01-2002, 10:19 AM

Hmm, since I'm about to order a new XP, I might get a Tbred then, I should be able to connect 1 bridge... I hope

How does it OC?
