Athlon XP 2400+/2500+ Mobile unlocked or locked ?

[estew33]

Hi All,
Does anyone know if the 2400 + and 2500+ athlon XP Mobile ( both Barton core ) are locked or not.
Thanks,
Ed
Another question, with the 2500+ retail barton now only 81.00 ( I think it is now ) from zzf and the 2400+ mobile from newegg costing 79.00 and the 2500+ mobile barton costing 95.00 from newegg. My question is which is the best deal.
Thanks again
Ed

yep. Unlocked by default.

Doesn't it have to be unlocked for the PowerNow to work? If so I'd imagine ALL the mobile AXPs are unlocked.

For your money, the best deal still seems to be the regular desktop 2500+ instead of the mobile AXPs. Even though it is locked, the 2500+ multiplier is at 11x which is perfect for most people. It allows them to up the crank the FSB up to 200 and hit 2.2 GHz out of the box (sometimes even with the retail heatsink). If you want to go any further past that you can probably raise the FSB incrementally and add voltage as needed, and you should be able to get a pretty good OC without ever having to touch the multiplier. Plus, since you are not just increasing the clock speed of the processor with a FSB OC, but also raising the amount of available memory bandwidth at the same time, so for example you are doing better overall by having your chip at 220x11 rather than 200x12, even though both OCs give you roughly the same final clock speed of around 2.4GHz.

I'd say go with the deskyop 2500+ and put the extra cash into getting the best HSF you can.

As of right now, the Barton 2400+ Mobile is $2 cheaper than the desktop 2500+ (a la the Egg). The mobile version seems to be the perfect overclocker: unlocked multi minimizing bottlenecks, runs at a lower voltage (less heat) and some folks have been getting them above 2600MHz. Craziness. I would not recommend a desktop 2500+ at this time.

If all cpu's have to be unlocked to run PowerNow, what about Athlon 64's and Cool n Quiet? Are they unlocked too? or is Q+Q just fsb adjustment? With Q+Q enabled, CPU-Z reports my cpu as 4 x 200 so I assume its not fsb...

The A64s are top-locked. The lower multipliers are available so Cool n Quiet can work. The desktop A64s are basically mobile chips, so AMD is probably saving money by throwing this feature in.
