Mobile Barton 2500 Unlocked ?
Are all Mobile Barton 2500 chips unlocked. I can get an "AMD Athlon XP
2500+ (Barton) 1.88GHz 266 FSB 45WMobile" chip for about $95 but I do not want it if it is locked. Anyone know how to tell ? Thanks, jmr |

ALL mobiles are unlocked so that they can use powernow's multi-changing to
save laptop power. They always will be. "Jim Reynolds" wrote in message news:rhoac.140962$_w.1608030@attbi_s53... Are all Mobile Barton 2500 chips unlocked.

ALL mobiles are unlocked so that they can use powernow's multi-changing to save laptop power. They always will be. This is a common misconception. The normal/BIOS/L3/whatever-you-want-to-call-it multipler can be locked without affecting PowerNow. In fact, I've commented in various places that I'm surprised that it's NOT locked, as the chips come off the same assembly line. The ability to change the multipliers through PowerNow is, of course, required for all mobile chips. So you will always be able to change the multiplier through this on mobile chips, though as soon as (or if) AMD locks the L5/L6 bridges as well, then you'll only be able to change it to below the default multiplier. This is the case, in the AMD64 mobiles, where there are no bridges. PS to the OP: the 45W mobiles are the good ones to get for overclocking, as opposed to the (cheaper) 70W DTR chips. -- Michael Brown www.emboss.co.nz : OOS/RSI software and more Add michael@ to emboss.co.nz - My inbox is always open |
