Difference Between 2500+ Barton and @2500+ Mobile Barton?

Mobile Barton 2500:
Unlocked
Less Power consumption meaning higher overclocking
$95

Desktop Barton 2500:
Locked
More power consumption
$80

You'd be better off with the 2400XP Mobile, its $16 cheaper and some people over at AMDmb have gotten them up to 2.5ghz on air cooling alone.
 
Differences are:

AMD Athlon XP Mobile 2500+
266 FSB
1.25V stock
Unlocked multi

AMD Athlon XP Barton 2500+
333 FSB
1.65V stock
Locked multi (week 39 and after)

I'd go with the desktop 2500+. The locked multi doesn't impair the FSB oc. 333 FSB > 266 FSB :)

Not necessarily. So you're saying the mobile 2500+ can reach the same FSB oc's as the desktop 2500+? I doubt you could push the mobile 2500+'s 133 FSB to the typical 220 FSB oc on the desktop 2500+. Lower voltage won't necessarily allow more oc room. Maybe the mobile 2500+ can take less voltage than the desktop 2500+.

Instead of speculating and basing your comments on a "maybe," perhaps you should try one and actually see what it can do? FWIW, my XP-M2500+ defaults to 1.45V (1.575V in a desktop mobo) and runs 227FSB with no problem. It's Prime-stable at 200x11 @ 1.55V. You can see my 24/7 config in my sig. You may also want to consider the fact that Mobile CPU's are rated for higher operating temps than their desktop equivalents.
 
I never said they were bad ocers. I am merely challenging the fact that they are better ocers than the desktop version. I hate it when people gripe about the locked multipliers and then go buy a Mobile 2500+ just for that sake.

I think that ultimately it boils-down to the luck of the draw. Although, I haven't seen too many desktop Barton's that can run 200x11 @ 1.55V.

Why? You, yourself, cited OC'ing FSB in your previous message. At the risk of pointing out the obvious, often a higher FSB can be had with a lower multipier.
 
i saw a guy on another forum who says he got his 2500m to 2.7gig. i dont know if he is using water or air cooling.. but that is a great overclock either way..
 
I'm confused by your various answers. Mobile 2500+ = unlocked multiplier lower FSB @ 266 and lower Vcore. Regular 2500+ = locked multiplier, higher FSB @ 333 and higher Vcore. (more heat).
Wouldn't the Mobile 2500+ be the better processor because of the potential better o/c'g due to the unlocked multiplier?
 
My 2400XP Mobile shipped today so I should have it by Tuesday at the latest I'll report my results.

Wouldn't necessarily be a better ocer. You're never guaranteed an oc. But the unlocked multiplier will give you more flexibility. Certainly worth paying $15 more.

Must be some confusion (on his part) as the mobile does run 1833MHz, but differing from the desktop counterpart in the FSB where the mobile is at 133MHz (266DDR) and desktop at 166MHz (333DDR). The extra bus is what affords the Barton an extra 100 PR points aside from the 256KB more of L2, so if this were officially a desktop part it'd be a 2400+ model but I'm guessing AMD considers it to be faster than the mobile Athlons so it can tweak the PR :D

In any case, I hope AMD doesn't start locking mobile multis but it's likely to if this catches on.
 
Mobile 2400 and 2500 are sold out at Newegg. Where else are they offered for a reasonable price?
 
my Mobile 2500+ came in today. its doin 2205 at 1.5 volts temps never got higher than 30c on slk800a with TTSF2 full load. this is much better than my 1700dltc at 2205 at 1.575. must try higher later.

this is what it said on the chip
axmh2500fqq4c k028535a40130
iqyfa0343mpmw
 
I have to go get a new power supply and then I'll see what I can do but I got my 2400 today it reads:

AXMH2400FQQ4C T818776K30144
IQZFA0347XPMW
 
I just got it setup, set the fsb to 166 (333) with a multiplier of 13 giving me 2241mhz and it booted up fine at stock voltage. I ran SiSoft cpu and memory benchmarks as well. I'm going to go for more shortly.
 
It's rock solid at 2300mhz (170mhz FSB), I'm just going to keep it at this for a while till I burn it in.
 
my is at 2310 now 11x210 on 1.5 volts. tmeps are still under 30c

NewEgg has a mistype, according to AMD's website the Mobile 2400+ runs 1.8ghz

The mobile processors have been getting high overclocking results because the mobile processor is basically the chips that where able to run at the same ghz while consuming less power. Less power = less heat. Heat is the limiting factor when it comes to overclocking and when you can run the same speeds with less heat that theoretically means that you can go faster before you reach the same heat level.

As far as the mobile's becoming locked, that won't happen. The reason i say this is due to the nature of the platform a mobile has to be multiplier unlocked so that when on batter power it can reduce the processor speed without affecting other components. It also lowers the voltage as it goes down, which is why there are some conflicts in what the stock voltage is. The XP2500+ for example goes between 1.25v on the low end up to 1.45 running full speed. AMD calls this SpeedStep I believe?
 
I think a [H] review is in order for this chip.

Maybe I'm just a dreamer, but this could be the perfect CPU... whether you are overclocking, gaming, or just a internet surfer looking for a ultra quiet PC. Low voltage/power consumtpion, high performance... ok not the HIGHEST but high nonetheless.

I think when I get some spare dough I'll be picking one of these up, along with watercooling paraphenalia, and see how quiet my room can get with the PC on :cool:
 
Wow, now I admit these chips are awesome. Lots of people hitting 2.7gHz with these and a Dtek WW over at ocforums.

My savior! That makes so much sense I am blinded by it :D Thanks for pointing that out.
 
/start rant
I find it so ironic that Intel came out with the Pentium M, that is so similar to AMD architecture. Kind of hypocritical that Intel is trying to convince the average Joe that megahertz doesn't mean everything for their Pentium M. Pentium also excels in the areas AMD chips excel in...games and business apps with branchy code...it also does more work per clock cycle. AMD did copy Intel though on that SpeedStep thing. Intel had it way before.
/end rant
 
i dont' beleive INtel is trying to tell anyone that Mhz don't matter concerning the P-M. They do not want to affect their p4 sales. Furthermore, intel is just dumping HUGE sums of marketing money and sweetheart deals with manufacturers to get them to use P-M. I am not saying P-M is a bad chip, it's a good chip, but intel has the resources to push it to the masses.
 
That and the "Centrino" marketing push. All of my dad's friends associate "Centrino" with laptops now. I guess Intel is very successful at brainwashing.
 
So guys now that you've hijacked my thread can someone who knows recap the differences I originally asked for?

Desktop Barton 2500+:

333 Mhz FSB ; 1.65v ; locked multipliers after week 39

Mobile Barton 2500+:

266 Mhz FSB ; 1.45v (laptop mobo) 1.53v (desktop mobo) ; unlocked multipliers
 
I think what you're trying to say is that it depends on the Core Voltage definition code... :rolleyes:

If the code is an "X" then the stock laptop mobo voltage is 1.25v. If the code is a "Q" then it will be 1.45v.

Most people that have received their mobile bartons are running 1.53v stock.. which is matched to the "Q" code which means 1.45v on a laptop mobo.
 
Quick question - Will any motherboard that will run a Barton run the mobile chip as well or is there a bios issue to deal with like the old K6-2+ and K6-3+ cpu's on a desktop socket7 motherboard had?

Does anybody know if the Mobile 2400+ is as good an overclocker as the Mobile 2500+? NewEgg lists the 2400+ as being in stock now for $79

Like I said earlier, I'm hitting 2.3ghz on my Mobile 2400+ I wouldn't call that bad at all.
 
how high will the FSB go on them?

I'm running my T-bred in my NF7-S and I kinda like the 220 FSB with DDR440 at a 1:1 FSB:RAM ratio...
