I love the 2500 mobile...

OCed from 1.8 to 2.52 (12x210)with no prob yet... ran Prime95 for 7 hours and is rock solid! voltage at 1.9 and runs at 53.5C on full load and around 47C Idle with my SI-97 and Vantec Stealth fan. I LOVE IT!!! any tips for getting higher?


just an FYI, i just upgraded from a 1.1Ghz TBird with 256MB of PC133 to the XP-2500M and 1GB of PC3200... its FAST! (and cheap)


 
hmm i gotta ask, what is the advantage to mobiles on a 754 over a 64 proc?
i think it just has an unlocked multiplier, right? i mean besides that it is massively overclockable.

he's talking about a mobile xp 2500+, which is based on socket A. mobiles are generally multilier unlocked, runs at lower voltage, and can take more extreme temps.

Nice for what, $75?

No more like 3150+ PR rated. When the 2.8C is about the same as a 3200 barton this is a 1.25:1 multiplier since 3200 is 2.2. therefore 2520 x 1.25 = 3150

lower heat due to .09u process, means higher overclocks while running at lower temps. which also = :thumbsup:

3500+ may be the PR rating of a 2.5 Ghz Athlon XP, but it is certainly not equivalent to an Athlon64 3500+ nor a P4 3.5 GHz.

The AthlonXP PR rating, first of all, was originally derived in competition to the P4 A and B (so 100 MHz and then 133 MHz FSB, not the 200 MHz FSB P4 'C' series with dual channel DDR).

Second of all, it is a linear scale (a PR of 100 points is derived from each bump of 66 MHz on clockspeed), so because of this linear relationship, as the PR rating goes up, it's accuracy becomes less and less.

so, a 1700+ at 1.433 MHz is definately as fast as a P4 1.7 GHz, but a "3500+" at 2.5 GHz is way below a P4 3.5.


Awesome results for a 2500+ mobile though; great chip at a great price (just don't have delusions that it is an Athlon64 killer 😉 ).

As an upgrade over a 1.1 Ghz Tbird, that's an absolutely monumental leap 🙂 .
 
I used the Abit NF7-S v2
Yes i did use the copper shim.... ive broken a few durons with out them.
It is certainly one heck of a upgrade... I didnt go for the A64 cuz i was on a $350USD budget... not much can be done with the A64 for that price range... im not a P4 fan, so i stuck with what i know.
 
im runnin a 45w 2400 xp-m @ 2.3 1.675vcore, 200x11.5, runs at 36C idle, 41 load, got it up to 2.4 with 1.8, but theres not much differ btw 2.3 and 2.4, but a lot between 1.7 and 1.8 volts

Love this chip, Mobiles are awesome

I see the same performance as the 3200...another rig of mine has the 2400+ Mobile @ 2.5GHz and it seems just as fast but less responsive prolly because of the reduced Bus speed.

You know that impossible to quantify but "seems ... less responsive" feeling I think is due the the very low latency of A64's. We are talking 3:1 faster here even with your excellently high FSB OC on barton according to programs like EVEREST. I mentioned this before... when I first got my A64 (@2560 initally) and was benching it against my 2.7 Barton. Everything just seemed *way* snappier on A64 dispite some similar benches or benches +-10%. Not descerable really.

BTW, Folks there is no reason to be buying Bartons right now IMO with OEM 2800's going for $110 and those cheap $70 NF3 boards out there.

Sweet, I was looking at the SI 97 for my NF7-sv2 glad to hear it fits ok. I hear you can drop another 3C by not using the shim but I know the SI 97 doesn't hit the pads very well without it.

You tell em Zebo. If you've got the extra $30-$40, go for the A64 2800+ and either an Epox 8KDA3j or a Chaintech VNF-250. Then slap on a decent HSF and you're cruising.

No Athlon xp is made with a 90nm process, sorry. They're 130nm.

I've got a 2600 mobile running at 250x10, 1.65v, 2-2-2-11 timings on an nf7-s with a gig of bh-5. Not a bad processor if I don't say so myself.

There's good reason to buy a mobile xp... let's say you already have a decent socket A mobo. A 2.5ghz athlon xp isn't far short at all (or maybe even better) than an athlon 64 2800+, and it's also ~$100 cheaper.
 
A64 = AMD ATHLON 64 2800+ RETAILED + CHAINTECH VNF3-250 or EPOX "EP-8KDA3I" = $192.00


Mobile Barton= AMD ATHLON XP 2500 mobile + SHUTTLE AN35N = $143.00 Still need a HSF!!! What's that cost? 20-$30?

The difference is a trip to Jack in the bOX

AX core A64's will clock the same, be about 10-30% faster depending, run cooler, use less power, have future 64 bitness, have NX bit to prevent malcious programs and finally has that unbenchmarkable "faster feeling" due to incredible low latency. abosolutly no reason to be buying Bartons at this time.

Notice I said, "you already have a decent socket A mobo," which most people considering mobile axp's do. It's plenty cheaper if you already have a mobo.

Who said anything about buying another mbrd?
When your buying just the cpu it is much cheaper😛


And yeah I love my XPM 2500 too 😉

XPM2500 @2.58GHz @ 1.71v 😀

Would "faster feeling" be the same as snappier which would mean the same as my less responsive? 😉...Anyways the only reason why I'm not using an A64 is because if I were to use one it wouldn't be Socket 754 so I'm holding out for the NF4 Mobo's before claiming mines 😛

I do have a Winchester 3000+ and an ASrock K8 Combo-Z ULi M1689 Socket 754/939- $75 but someone will get that for Xmas :gift:
 
I decided to get the XPM 2600 which I have at 2600 Mhz over the 64 because that would mean (to me anyway) that I would have had to get a new SATA drive, probably a Raptor, since the cheap Shuttle Ultra AN35N was IDE only. I decided that going from an AXP 1400mhz to a 2600Mhz was good enough for me. Plus, I saved on HDD ($105) CPU ($25) and mobo ($20). my box runs fast as hell.... to me. I'll be upgrading once the 939/PCIe SLI boards become mainstream.
