How to unlock multiplier on 8rda+?

[Digerati]

I have a new AthlonXP 2500+ Barton running on my Epox 8rda+ mobo with the latest bios.

I currently have the multiplier set to 12.5x166 giving me 2800+ performance and temps of around 41C at load.

Anyhow, the multiplier in the bios will go higher than 12.5, but if I set it higher than that, when I reboot it starts up at a default 11x100.

My question is how do I unlock the multiplier so I can try out 13 and above?

Thanks!

and i know i can cut the L3 on the chip die, just wondering if i could just do it through bios.

not posible to my knowledge, you have to Modify the chip.

Check Tomshardware guide, they have a walkthrough on how to do it, its quite simple.

so Bartons dont come factory unlocked like the tbreds?

not many tbreds come unlocked, i don't think.

anywho, i thought a lot of nforce2 boards could unlock multipliers..?

They do, i increased the multiplier in bios to 12.5 and now i have a 2800+ (2.08 ghz)

My tbred is unlocked and was like that when I got it I can set the mulitplier at whatever setting I want .. all through the bios sometimes I run it at 142x12.5=1.775ghz or like right this minute at 11.5x150=1.725ghz

its an Athlon 1800+ default would be 11.5x133=1.53ghz

So some are unlocked and some are not ...
