Athlon Mobile XP 3000+ - need advice
I'm debating a CPU upgrade from my Athlon XP 2000+.
http://www.newegg.com/app/viewProductDe ... ory=BROWSE.
as i understand it, these chips come unlocked, which gives me this nice choice of running low voltage (possibly with passive cooling) or overclocking to get speeds approaching the non-mobile Barton 3200 XP.
I'm a little bummed i wont be able to take advantage of the 400 fsb speed capacity of the mobo i recently bought. however, if this chip is cool enough to alllow passive cooling, i can easily accept a 10-15% performance drop relative to the BARTON 3200+ standard chip. does the 400 fsb really matter than much?
what is my best passive cooling option for this thing? how about: http://www.newegg.com/app/ViewProductDe ... 044&depa=0
Current system:
Antec Sonata case (treated with dynamat)
MSI K7N2Delta (with fan control for CPU fan)
Geforce FX5600XT 256 MB ram (with thermaltake blue orb fan - 26.4 dba)
1 Gig Samsung DDR400
Athlon XP 2000+ with OCZ Goliath SE cooler (very loud 80mm cpu fan)

Look for the user silvervarg. He has a regular XP undervolted running passively. There are also several threads discussing passive cooling.
Search for : "passive athlon"
In the author field add : "silvervarg"
hope this helps. Msg silvervarg on the board he still checks fairly regularly iirc.

"I'm a little bummed i wont be able to take advantage of the 400 fsb speed capacity of the mobo i recently bought."
But you will. The XP-Ms have an unlocked multiplier so you find the best balance between FSB and CPU speed. I run mine on a 430MHz FSB.
Don't bother with the 3000+ it needs higher voltage to get it to those speeds. I recommend the 45W version of the 2400+M or the 2600+M

Yeah I run my 2500+ at stock speeds and voltages for a good noise/performance balance most of the time. Then I use the excellent CMOS reloaded feature that the DFI has and boot into the overclocked profile when I want to do something more demanding. A restart later and a few turns of some fan controller knobs and bam I have a 2.43 GHz machine.
Re: Athlon Mobile XP 3000+ - need advice
The link you give is a DTR model, so as far as I know DTR models consumption is 72W.IGMorton wrote:I'm debating a CPU upgrade from my Athlon XP 2000+.
http://www.newegg.com/app/viewProductDe ... ory=BROWSE.
Other models 2400M, 2500M & 2600M (not DTR) have a lower consumption, 35W, 45 or 47W, and lower standard Vcore, 1.45V instead of 1.65V for DTR.
So the only advantage of these DTR models is the unlocked multiplier.
With DTR you will have to deep underclock and undervolt to run with passive cooling.
Look carefully on newegg site, the DTR model is the only they don't specify consumption
For the others, they specify 45W or even 35W:
http://www.newegg.com/app/ViewProductDe ... 400&depa=0
http://www.newegg.com/app/ViewProductDe ... 401&depa=0
With the item # you can spell the charcteristics of the CPU, for exemple the one you linked Model# AXMA3000FKT4C
AXM: Athlon XP Mobile
A: 72W
3000: 3000
F: OPGA format
K: Vcore=1.65V
T: Max core temp=100°C
4: Cache L2=512Ko
C: FSB=266Mhz
The rules to identify a mobile CPU:
Consumption (fourth letter of model #):
G (47W)
H(45W)
S(25W)
D(35W)
A(72W)
Vcore:
Q(1,45)
K(1,65V)
J(1,35V)
Cache:
4 (512KL2)
3 (256KL2)
Hope it's clear
AMD doesn't give the identification rules of mobiles on their site, because they are supposed to be sell on OEM basis to laptop manufacturers, so I took this information on many forums and made an excel table.
If problems of understanding, please ask me.
Thanks. Decided on the 2600... but more questions
thanks so much for the info. 3 short questions for you Athlon mobile clocking gurus:
1. which of these two 'steppings' would you choose?
Model: AXMG2600FQQ4C
Stepping Code: AQYHA 0431APDW
http://www.excaliberpc.com/product_info ... ts_id=4144
or
Model: AXMG2600FQQ4C
Stepping Code: IQYHA 0429SPMW
http://www.excaliberpc.com/product_info ... ts_id=4329
2. what voltage range would you recommend i experiment with for keeping heat low enough to be managable in a 74 degree ambient environment with a nexus 92mm fan (27 cfm) on a thermalright SI-97 CPU heatsink? that fan only produces 19 dba, so i presume noise will nonintrusive relative to the stock 120mm exhaust, 120mm nexus intake and stock PSU fans in my 2nd generation Antec Sonata. i presume i wont mind running that fan at full speed to attain maximum performance for this combo.
3. is this the right approach to begin tweaking with? first: set CPU voltage to some middle range you recommend (maybee 1.5 V). second: since i seem to remember keeping my first generation Samsung DDR400 stable at 213-216 FSB on a previous mobo, tenative plan is to set the FSB at 210. third: slowly bump up clock multiplier till system crashes.... if it does, try a tiny boost in voltage, run some benchmarks and monitor temps?

Better than all my confuse explanations in bad english, herre is a useful link to identify all AMD's CPU models:
http://www.amd.com/gb-uk/assets/content ... 05_ENG.pdf
1) The stepping it's another thing, and except week, year of place of manufacture, there is nothing sure, an exemple:
IQYHA 03 52 M P M W
IQYHA = Stepping
03 = Year of Production
52 = Week of Production
M = Day of Assembly /M = Assembly lots combined
P = Assembly Location: Fab30, Dresden, Germany
M = Lot sequence of the day
W = Combining Wafer lots prohibited
The only things are reports of overclockers, each one posting his stepping and result, but if you plan to undevot/clock..........
A useful link to overclock results per stepping:
http://www.ocforums.com/showthread.php? ... did=287973
2) Vcore & FSB:
To reach passive cooling, you'll have to underclock and undervolt you CPU.
The process is the same that for overclockers, find the best combination between Vcore voltage, FSB and multiplier.
So you'll have to test, and reboot, change one parameter, reboot, re test etc.............to finally find a combination which satisfied you.
One important thing is to change parameters (FSB, Vcore voltage & multiplier) one per one, because if you change 2 parameters and the system doesn't boot you'll not know which of these 2 have made it unbootable or unstable
There's no mathematical rules, I suggest you to boot first with nominal parameters, and try and test changes, try boot and stability.
The result you can reach depends of many hardware factors, you motherboard, ram etc
The advantage of a mobile is that theses 3 parameters are unlocked and you can change them not only by the bios but also by software once under windows.
I haven't mobile yet, I plan to buy one soon, so I can't report my own results with mobile, my target will be to reach passive CPU cooling.
Now I have an Abit NF7-S, and a desktop Athlon Thoroughbred XP 2600.
For my low CPU use (only P2P, surf, and Office pack) I undervolted and underclocked it as follows:
Vcore:
nominal: 1.65V
now: 1.17V (my mobo range begins at 1.1V, but under 1.17V the CPU does'nt boot)
FSB:
nominal: 166Mhz
now: 80Mhz
Multiplier:
nominal: 16
now: 12
CPU temp on idle (with 2*120mm case fans at 5V):
31° C with Silentboost at 5V
42° C with Silentboost passive
Consumption:
nominal: 68W
now: 15W (in same conditions with a mobile I'll be under 12W)

IGMorton - The stock PSU fan is pretty loud BTW, once the rest of your rig is quiet it will start to bug you
If you get a fan controller you can turn the fans up for CPU intensive tasks or if you overclock. Also it should be very easy to passively cool that grpahics card, a 5600 doesn't produce much heat at all.
"I currently run a 2500+ mobile at 2.2GHZ, with an extremely quiet fan. It is nearly silent and my temps are about 53/32. (constantly running folding@home)."
