XP 2500+ vs. XP-M 2500+: Same o/c abilities?

Hey, just wondering if anyone knows the dif (if any) between these 2 XPs in overclocking.

Recently, I keep hearing about the XP-M overclocking @ 2.4, but nothing about the reg. XP.
 
The 2500s are locked, which means if you have pc3200 ram, you can only do 2.2ghz and stay at ram speed. With the mobile 2500s, they are unlocked, so you can do 12.5X200 which is 2.5Ghz.

Also, if the 2500 Ms can do much higher clocks then the 2500s.
 
Even when they were unlocked, they were still "only" going to 2.3Gig if you got a lucky chip. The mobiles are unlocked and overclock higher, speculated to be due to their higher rated temperature limits. The "worst" of the mobiles seem to be in the 2.4 range with 2.5 the average and 2.6-2.7 with highend/liquid cooling. They also take less voltage to reach similar speeds.

2.3Ghz @ 1.75V Actual here... Mobile Barton 2500+... so I must be quite unlucky.

It depends on your stepping... the IQYHA ones are the most desireable... and what are currently shipping from newegg to my knowledge. I got mine less than 2 weeks ago, and it's an IQYHA. Currently I'm running 209x11 @ 1.65 v (actual) until I get a better power supply (TruePower 430 is on it's way) because my SL350 isn't cutting it anymore. The CPU draws so much more current at 2.5 Ghz that all the voltages are all over the place... maybe with the new PSU I'll be able to get to 2.5 Ghz on 1.65-1.70 volts... maybe even 2.6 Ghz on 1.750 volts. I'll have to wait and see =)
 
Could someone explain what the Athlon XP-M is? I thought it was the mobile processor (for use in notebooks)?
Is it the exact same socket, etc. as the regular XP? Same cache, etc.? Otherwise identical?
What is the differnce, other than being unlocked?
Thanks,

So, they have less cache, and are slower clock speed, yet are more overclockable??
I don't see the point. Not sure why another poster said that they were "the same chip as XP, except they were the cream of the crop". That's not true is it?

The XP-M is the Mobile Athlon XP... XP-M is the correct name for it according to AMD.
The CPU being a mobile processor has absolutely nothing to do with the amount of cache. The amount of cache is dependant on the core. If it's a Barton core, it'll have 512k, if it's a Thoroughbred core it'll have 256.
 
Never mind, saw the 2600+ at newegg.
Darn, I wish that posts could be edited or deleted.

They can be edited with the edit button. AMD's website says the mobile line goes up to 2800+ but I don't recall seeing anything higher than the 2600+ for sale anywhere.
 


Unlocked should be enough incentive for most tweakers. As an added bonus you get chips which are hand picked to run at Low Vcore meaning they they will OC like crazy when higher Vcore or even regualr barton vcore is applied.

I've rarly seen a regular barton running that. Seems pretty lucky to me. You can't compare to others unless they show a screen with prime 12 hours next to cpu-z😉

That will be my next task after I get my new PSU 😀
 
I have my Barton Mobile running at 2473mHz (11.5*215) at 1.68-1.70 actual. I can run it stable at 12.5x200 at the same voltage too.
