Check out MOBILE 2500+

Oh man do I want that chip. It says IQXEA in the photo so its new. Look at the die.... it's long so it is a barton. Contradictory Bus info on the egg but who cares surely we wouldnt be using it anyway! It is labeled a weird GHz number that is hard to distinguish multi *fsb but we pretty much know it approved for higher than reg 2500+ MHz at 1.5v.... enter the 2500+ dlt3c I figure! Hopefully in similar dlt3c fashion, no problem on NF2.

kudos to pakotlar at H for linkage.

edit: and to think I forgot to add these

Aren't they suppose to have a fsb sensor. I'd like to get a hold of a 2800+ mobile chip.....

[ellsworth]

what does fqq4c stand for? i dont have my amd chart handy. those numbers determine the voltage and whatnot.

[felix88]

looks interesting. the old Mobile Palamino chips used to overclock pretty well, so i'm sure these do too.

[saaya]

keep us updated about how it ocs

[felix88]

i'm seriously thinking about buying one. unfortunatly i've gotta pay of my CC first, and if i keep buying stuff like this i'll be in debt forever.

What does it mean when it says 256K in that spec?

256K cache?

What exactly is the difference between the mobility Athlon and the TbredB/Barton? These are the things you need to investigate b4 assuming you can plug one of them into your socketA...

[texuspete00]

Theres contradictory cache and bus speeds. Its fubared. I think its just a plain ol' 2500+. I think it will work in socket A for sure. Cant you use dlt3c's in laptops.

[saaya]

its a 2500+ so it has to be a barton, it runs with only 1.5v so its a nice chip whether its a real mobile chip or not. and yes, you can use mobile xps in destop machines, they are basically the best chips amd can pull of their wafers, the ms are the chips that clock to high speeds with low voltages.

its the same core as the desktop xps. im not sure if it could be using less cache though... cache is something that eats up a lot of juice so they might have disabled some cache? but i dont think so...

somebody please buy it and tell us how it performs, i live in germany and it would take 2 weeks before i can tell you how it performs, if id live in the us or they would ship to germany id buy one right now.

There are not many Barton chips that I've seen so far on this forum that can run default speed @ 1.5v.

It doesn't matter what it can run at default V's.

The first 2500+ I got needed 1.8v to do 200x11 (3200+) stable. On the other hand, it didn't complain when I put 2.15v through it. If I had sub-zero/ambient cooling I'm sure this Barton would rock!

The next 3 2500+'s that I tried all did 200*11 at stock voltage. But 2 of them didn't post if I turned vcore above 1.95v, and the other one couldn't even do 2.4 @ 2.0v.

What I'm trying to say here is that Barton cpus don't necessarily scale with volts.

AXMH2500FQQ4C ... Q=default voltage of 1.45v 4=512kb L2 cache C=333fsb
keep in mind that its a 333fsb cpu, so it runs 1.88ghz with only 1.45v! now show me a barton that can do 1.9ghz with 1.45v!

could anybody with a 2500+ check out how high he can get that cpu with 1.45v?

the best ive heard so far was 2.2ghz with default voltage of 1.6v or 1.65v, i wonder how high that barton clocks with only 1.45v.

hold on! http://www.newegg.com/app/viewproduc...=mobile+athlon

theres also a mobile 2400+!!! AXMH2400FQQ4C
it has 512kb L2 cache but its a 266fsb cpu sooooo it runs 2ghz with only 1.45v!!!

2ghz barton with 1.45v now THAT sounds good!

[saaya]

the 0330 seem to perform extremely nice! one guy got his 2500+ 0330 to 2.54ghz on air!!!

amd always uses the best chips for mobile cpus, just like intel. check out the pic of the mobile 2400+ those seem to be 0330s

and the 2400+ is only 100$ , 10$ cheaper than the lower clocked 2500+

hmmmm it runs 2ghz with 1.45v.... my 1700+ dut3c needs 1.6v to run 2ghz.... i think ill be the guinea pig and be the first to try one of those mobiles

[saaya]

ive searched the net and there are 3 diferent versions of xp-m chips.

xp-m dtr (desktop replacement) socket a , 0.5-1v lower default voltage

xp-m (mobile xp) socket a , 1-1.5v lower default voltage speedstep

xp-m (low voltage mobile xp) mpga , 1.5-3v lower default voltage speedstep

now im not sure if they all support speedstep, but the dtr's just dont use it because the mainboard doesnt support it and if you can use a mobile xp in a desktop board and have the speedstep deactivated.

but i think speedstep wont be a problem. i doubt that it works at all in desktop boards, and if it should work im sure you can disable it by manipulating the bridges or pins of the chip

[ellsworth]

that looks very promising saaya, too bad you have to wait so long to get one. i would get one if i had enough money...

[B5I8]

Something doesn't seem right about the specs at Newegg.

This is the model number:

AXMH2500FQQ4C

And this is the breakdown of FQQ4C:

F - OPGA package type
Q - 1.45V Operating Voltage
Q - 100°C Maximum Die Temperature
4 - 512KB L2 Cache
C - 266MHz Maximum System-Bus Speed

[ellsworth]

well thats what it says in the pic, so im not argueing its validity . 266fsb is a bit weird, it must have a higher multi than the usual 2500+, im not sure if thats good or bad.

[felix88]

anyone have a link to those codes? i'd used to have the AMD datasheet saved, but i seem to have lost it.

[B5I8]

I've finally found the specs:



Taken from this page:

[felix88]

nice find.

i also found this:
http://www.amd.com/us-en/assets/cont..._Rev03_ENG.pdf

it'll let you decipher any of the codes found on AMD chips.

That ones not bad either. Don't know how they expect to pass a a pic of a 2700 off as a 3000+ though.

I'm pretty discerning when it comes to processors today...

[saaya]

but according to newegg the 2400+ has a 266fsb and runs @2ghz, and from searching the web a bit its not the only page selling mobile 2400+ chips with 266fsb and 2ghz clockspeed.

i have no doubt that this cpu runs at 15x133, just check out the code. and if it doesnt run as is indesktop boards im sure its no big deal modding it.

LOL!

saaya, given that you've already done all the research I don't suppose you might have stumbled on any UK sites selling those mobile cpus....?

[mongoled]

Mmmmm lol @ MrL,

Was thinking exactly the same thing myself, once i get back into the UK im going to be buying a barton chip and most probably a abit n7s-ver2

So any info on UK availability for these chips would be well appreciated!

Thanxs

The mongoled one

[saaya]

its settled liquid3d will buy one for me asap

i foudn some other shopy, but they have diferent steppings, their default voltage is 1.5 or even 1.55 and theyre not week 30 wich seems to be amds new miracle stepping. check out the pics on newegg, they are either week 30 or later but since newegg buys them in large quantities i bet they bought a bunch of week 30s.

[saaya]

mmmhhh cant wait 45W@2ghz... this means it could be cooled by a radeon 9800pro hsf!
