Athlon xp 2500 mobile

[bde]

Hi I wanted to buy a mobile 2500 athlon xp, I've heard that mobile cpu?s are good for overclocking and what not but would it be as good as a athlon 64 after I overclock it?

Yeah it's a good CPU, you can get it from Bigfootcomputers.

If you have (as in your sig) a non-mobile already at 2200mhz I wouldn't waste money on a mobile. You can get up to around 2500mhz on air with a mobile with the right stepping (starts with I) but I would save my money and get a bigger upgrade later, there's really not THAT much of a difference between your CPU and a mobile version.

So you're saying it's not a good thing to dump the barton 2500 in order to get a mobile one. I disagree, I think that if he gets the moble barton his chances a achieving more than 2.2Ghz are better than the normal bartons, and they say that the 2500-M at 2.5Ghz can match some Athlon 64 CPU's.

 

[blacktankofhopelessness]

Of course his chances are greater of reaching a higher overclock. But is it worth it really? Dump your old one and get a new one based on the exact same core, only for a slightly better quality chip? If he can get a good price selling the old one, sure! Otherwise I wouldn't bother myself. But maybe that's just me. 2200mhz is already at 3200+ speeds...

My problem is in running a retail XP 2700+ I can't reach 200FSB - only 166 - , so my pc3200 memory is only running at 333 MHz. My hope is that with a mobile XP 2400 and better cooling I can reach 2400 MHz (200 x 12) and be able to run my memory at 400 MHz. This is on a Shuttle AN35N Ultra MB in a modded case with lots of air cooling.

I have my athlon xp 2500 mobile running at 2.4ghz all the time, it runs under 40c and gives me a performance increase over my regular xp3200. In answer to your question no an overclocked athlon xp 2500 mobile will not be faster than an athlon 64.

If 200 fsb is your goal and you think it's worth the money, then go for it. You will most likely get to 200 fsb with a mobile combined with the Shuttle and PC3200 memory. I'm severely motherboard limited in my overclocking...

 

[Assimilator1]

Well I reckon I can lay claim to the title of 'worst overclocked speed achieved on a Barton mobile!'
It's an XP2400 M

The damn thing won't go over 2.13GHz @1.65v,gonna confirm on another rig tonight.
Upping the vcore any further just causes it to crash or fail to load windows
And yeah I have good cooling ,GW CAK 88T (large ,all copper HSF)
Tried plugging in another PSU soley for the mbrd,didn't help

I wasn't asking for much ,just 2.4GHz!

I might sell this 1 & buy another......

it's a very risky business this overlclocking, I mean you gotta be lucky...
I have a normal 2500 barton athlon xp that I tryed to oc to 3200 (200x11) but it NEVER stayed stable.
good cooling? yes SLK 800 (heatsink) and a volcano fan only.

My ram has failed me at all voltage. (geil gold dragon pc 3200 dual channel 400Mhz 512 mb)

so I have it oc'ed at 2800+ only

What voltage are you running on your RAM? I have the same stuff and I have it at 220 MHz at 2.95 VDimm (it will actually do 225 or higher bu my proc doesn't like that with a 10+ multi so I geared it down)

You might try adjustingv the latencies on the stuff..... run it at 2-3-3-7, and try that.... my friend tells me (I haven't had time to test this properly) that Athlon's aren't too happy with the last number being even..... so the SPD settings for the RAM are 2-3-3-6 so change that to an odd number like 7 and you should be okay.. or test it one stick at a time and if they both work try running them single channel instead of Dual... worst case scenario, call GeiL and ask them to send you two new sticks.. they have a lifetime warranty after all.

 

[3LEMENT0]

mobile chips overclock really well with the right components and the right setup. But it's really up to you if you want to go though it, it takes a lit of time to test everything to be stable. Took me 1 week after assembling the hardware to make sure my rig passed memtest/windows memory test/sandra benchmark/prime 95/cpu burn/super pi and a host of other benchmarking tools to make sure my overclock is stable. I'm running my mobile at 2.53Ghz Good luck...

 

[bde]

on the NF-S abit board I can`t do 2.95 or anything I have choices from 2.7 to 2.9 only.
I have it at default now with 200x10.5 I`ve tryed all voltages but nothing.. I get errors and stuff

my ram is at SPD, so im gonna try that last digit 7 instead of 6 and we`ll see what happens.

good luck.... you may want to try memtesting at different values for hte last number.... 7 9 11 you get the idea. It is a shame you can't get to 2.95, I haven't ried mine at 2.9 yet to see if it works. Currently I am seeing hte lowest voltage I can use on my proc to keep it stable... it is looking like 1.78 or so... not too terribly bad bad a little higher than I would have liked.... oh well

 

[bde]

it has failed again for the 10000000th times, so im at the same 200x11 but higher voltage to 1.85 and the timing is at 9-3-3-2, ram voltage 2.7
I HATE MY COMP

 

[Toro 45]

I can't see how your ram can be holding you back but have you tried one stick at a time? AMD setups like the last number at 10 or 11 on the ram,also try your first number at 2.5 or 3. I noticed you had it at 10.5 and at 11 multiplier so I take it your cpu is unlocked, have you tried it with a lower multiplier like 8 or 9 with the fsb at 200 if it runs stable there it may very well be a ram issue.

Don't you mean a CPU issue? ,with a lower multi naturally its going to drop cpu clock ,not RAM


I tried my XPM 2400 on my friends Abit NF7S ,whilst he didn't get the wierd problem of crashing when vcore was taken above 1.65v (which is odd too) I couldn't get the CPU to go much higher.At 2.2GHz @1.75v it still wasn't stable so I gave up at that point ,I don't run XP cpus above that in normal use so there wasn't much point me upping the vcore further.I guess it might of been stable at 1.775 or 1.8v.
In my Asus A7N8X ,being unable to increase vcore above 1.65 limited it to 2.13 GHz ,though that was tested & stable for the short time I used it.

I've ordered an XPM 2500 ,I hope that overclocks better!

 

[xXFaNtAsMaXx]

The AMD Athlon XP 2500+ is a very good CPU. It can easily be overclocked to run just like an AMD Athlon XP 3200+ with not-so-special cooling.

 

[Lark888]

I am running Barton XP2500 Retail at 11.5*200 with a slight bump in voltage on ASUS A7N8X Rev 2.0 board. This same chip would not go above 190 on a A7N8X Rev 1.4 board (same memory also). The ASUS board is a little fussy about overclocking at the 200 FSB speed. My memory is nothing special - in fact I surprised it's running at all (Crucial 2700 DDR stock at 3-4-4-11).

I picked up this thread since I am looking to buy a new XP-M for an ABIT board that has been sitting around waiting to be born again. Still can't decide between a 2600XP-M or 2500XP-M. Price is close ($9 delta).

 

[xXFaNtAsMaXx]

Go for the 2500.. It will more than likely overclock better than the 2600 anyways.

 

[Assimilator1]

Why do you say that?
Chances are the 2600 is more likely to hit a higher speed

Lark888
Interesting ,I have the same RAM as you & the rev 1.04 mbrd.
Good to know its likely limits

But is a 190MHz FSB with 3-4-4-11 timings going to be faster than 177MHz with 2.5-2-2-10 ?

Thanks for catching that, I meant to say it may very well not be a ram issue.


Assimilator1, what are you using to cool your cpu? and did your friend have a quality psu as well as yours? The one thing I keep seeing with pushing these mobiles is it really does take a good quality and powerful psu. I've been using a couple of generic 300 and 350W psu's along with an Enlight 300W and a Antec300W with my XP-M2400 and depending on which psu or mobo I have it in it might run 2368mhz or up 2500mhz.

I finally settled on the Enlight after the Antec started randomly rebooting with speeds in the high 2300's after switching to the Enlight, I was rock solid @215X11.5=2478, that lasted about a week and I started tweeking again and bam now she's struggling for 2300 again. I just ordered a 400W Coolpower psu off of Newegg in hopes of hitting and staying near2500mhz.

bde, if you sell your cpu here it wouldn't cost much more to buy a mobile and at least you can spend some more time pulling your hair out trying to find the perfect overclock

 

[Assimilator1]

I got an 'el cheapo' PSU (qtec 550) ,but as I mentioned in my 1st post I tried a 2nd PSU ,that is running 2 at the same time, qtec 550 powering some fans,HDDs,CDs & a Magna 500w powering the mbrd only.
It made no difference ,I think my friends PSU is a qtechnology (not the same as qtec) ,I can't remember the name but it had 1 120mm fan & it was black
I guess you missed my 1st post as I mentioned the cooler too ,lol ,its a Global Win CAK 88T ,a big copper beast

I did forget to mention that my friend runs an XPM 2600 in that rig at upto 2.56GHz!:Q ,so his PSU is good,

<--- is jealous!

 

[Toro 45]

I did forget to mention that my friend runs an XPM 2600 in that rig at upto 2.56GHz! ,so his PSU is good, if thats the case and your chip barely hit 2.2 in his setup, then I agree that is one of the worst overclocking xp-m's around :shocked: Good luck with your xp-m 2500 and let us know how high it goes.

 

[Assimilator1]

Thanks,maybe I should start a new thread? ,'post your worst overclock!' .......

Checked the post tracking &amp; I wont get it till Monday
