Are Athlon t-breds already unlocked?

[dmw16]

I have heard that on nForce2 boards t-bred B's dont need to be physically unlocked. Is this true? How do I know if I am getting a rev. B when I order?
thanks,

In fact it is true. I plugged my TBred 1700+ into an Epox 8rda and without modification it runs at 11.5x166.

my tbred can run @ 19 or 18.5 x but thats not worth it so i run it @ 12.5 i think.

Nice. Unfortunately I am only running a TBred A.

Woah, these things are unlocked? Maybe I will try some overclocking after all... 😉

It is the motherboard that is allowing that for you.

the NForce2 and KT400 motherboards (don't know if it is all brands or just some.... read the specs.) have the 5 bit FID override feature which lets you select multipliers for T-Breds (and Bartons).

I'm using 12.5 even as we speak :beer:

yep hjeres a old screeny.

Unfortunately, even with an nForce2, you cannot automatically assume you can unlock a Rev A/B without any modifications. Only some nForce2 boards will allow both the lower and higher multiplier settings without need to modify the processor. In order for me to use the lower multipliers with my Soltek SL-75FRN-L and my old Asus A7N8X, I still had to use the "wire trick" to short the L3 pins on the back of the CPU.

The Epox 8RDA is one of the few nForce2 boards I know of that seems to allow total freedom in manipulating the clock and FSB settings.

In fact, it seems that AMD is shipping all Tbreds so far with unlocked L1 bridges, thus allowing for multiplier selection even on older motherboards/chipsets which have this feature enabled in BIOS or by jumpers/switches.

Also, it seems that most Nforce2 boards have a special feature that makes it possible to change multipliers even on locked CPUs, bypassing the need for physically connecting the L1 bridges.

So, it's not a particular combination of Tbred CPU + Nforce2 mobo that does the trick, but rather either one of them.

Can anyone tell me how to delete it?

my Abit NF7-S too.
and the t-bred a's are unlocked, only that your mobo needs to be able to identify them

MarkHark:sorry, you can't delete double posts.
