Unlocking Athlon motherboards by wiring the socket?

[Wombat]

When I read about this the first time, it was still a developing art. It should be pretty defined by now, so does anybody have a guide?

There's an intriguing reference to BIOSs that allow unlocking of mulitpliers - anyone know which boards they are for?

Thanks

Seems eazy, might test it

Every decent nforce2 motherboard but only with T-bred B CPU´s. Asus is a bit complicated because sometimes it only allows to access the higher multipliers and MSI is lacking that feature, AFAIK.

So they can be unlocked WITHOUT the wire trick, or they're the only ones that can be done w/ the wire trick?

T-bred B´s (2400+ upwards) will be fully unlocked with most of nforce2 boards, without need for the wire trick. At least Epox, Abit, Soltet do it. Asus does have some troubles - sometimes it does, sometime it doesn´t, don´t know if they already fixed it with a bios release.

Multiplier locking is a physical thing on the chips traces, that's why the wire trick work.

I can't really see how that could be changed in bios, and besides IF there was posible to do through BIOS se'd seen tons of hacked bios'es

Well they can, it seems to be only KT400 and nForce 2 boards that have this feature so I guess the chipset must have something to do with it too

Again, that´s why it only works for T-bred B´s! All other socket A cpu´s are hard-locked and must be modded in order to change the multipliers.

Unlocking the Athlon XP (Thoroughbred A, Thoroughbred B,, and Barton core)

If you are an owner of any recent motherboard (All Epox Nforce2 boards included) you do not need to unlock your Thoroughbred or Barton processor. This is done automatically through a software trick built into board. If you look carefully, you can see that the L1 traces on these chips are already connected! (via the green traces seen below).

Go to some forums like www.amdmb.com and see how many people are unlocking their T-bred B´s with nforce2 boards.

Yup! That's true... L1 traces are connected on all Tbred-B's... You can easily change the processors SUB_ID by cutting L3 traces...
Here's a link.

Uhm that's not how I read it, he say's his Barton is unlocked but that doesn't necessarily mean the board unlocks it, he could have modded the chip

Nice to see another XP333-R user here
