Letters on XP-M may be important??

[Gogeta_G3D]

I just counted up all the mobile that were listed in the oc result list, regardless of model, stepping, date, just the letters, that got 2.7Ghz or higher. i got this:

spmw 1 1 1
WPFW 1
VPMW 1 1 1
MPMW 1 1 1 1 1 1 1 1 1 1
RPMW 1
XPEW 1
XPMW 1

i suppose its safe to assume that if the other ones were able to hit 2.7ghz equaly well, people would have listed the highest oc.
again, im just trying to makes sense of this madness and maybe find a pattern. I do think any MPMW is likely to do over 2.6ghz, i searched on google and most were very good oc. maybe im imagining things, but its a start i guess.

[Gogeta_G3D]

Here what I got for 2.6Ghz: again, regardless of model, cooling, stepping, etc... just those four letter:

2.6

TPMW 1 1 1
MPMW 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
SPMW 1 1 1
WPFW 1
WPMW 1 1
VPMW 1 1 1 1
XPMW 1 1
RPMW 1
XPEW 1
VPAW 1
UPMW 1 1 1 1 1

i got the rpmw =(

I've always maintained that those four letters do mean something, and just because we don't know what, doesn't mean they're unimportant.

Thanks man for your observations!

I just ordered on of these and will see what we get sooner.

cool. I did too. do you know your full stepping? mine is from excalibur, 0351MPMW.

[Gogeta_G3D]

Also, newegg is shipping TPMW 2600+. Every single chip Ive seen that ends in TPMW was very bad oc. I got one, best it can do is 2.5ghz @ 1.95v.

[musk]

Is there a correlation btwn those chips and one particular Mobo or Memory?

It would of course be in the best intrest of OC'n to know that.

your logic is flawed. no ones sees this ????


you have to also state how many DIDN"T reach 2.7ghz. maybe AMD ships out 90% of MPMW?? if thats the case, then MPMW is actually the worst. you get it???

its like saying honda's are the number one car stolen at 50%. but if 99% of the population of the people own honda's, then the chances or YOUR honda being stolen is far less with so many other hondas out there

yeah its not perfect. I wish I knew details like that, would make things easier.

[Sentential]

I think I see a pattern

the chip with the lowest letter seems to OC the best

MPMW 1 1 1 1 1 1 1 1 1 1
RPMW 1


M comes b4 R

[glock19owner]

I have a 2600 XPMW that does 2.6Ghz at 1.77v's...2.65 at 1.82...still OCing so dont know what my max is right now...

The 1700+ TPXW's did notably worse than most other steppings.

The 1700+ XPMW's did better than all else, AFAIK.

It's very difficult to find a pattern, however, there's no doubt that the four-letter codes have some significance.

yeah, the WPMW on the 1700+ did even better. I used to subscribeto lowyat, a malaysian forum. WPMW were THE stepping to have. the amd chips are made in malaysia, so these people had all the know about the chips. my 1700+ xpmw did 2.3ghz, my wpmw did 2.4ghz. there were people on those boards that did 2.5ghz with very little voltage. Im not sure if the same pattern applies to the xp-m bartons though.


and yeah, now to think of it, any chip remember seing that was TXXX generaly was not a good performer.

[Gogeta_G3D]

Check this out, this guy at amdb found this out. I knew TPMW was crap. and btw, the one excalibur has now is the 0351MPMW 2600+.

"""""I just received my 2500+ mobile IQYHA 0352 MPMW processor from www.excaliberpc.com. This processor is what the mobile 2500+ is all about. I currently have this processor running stable @ 11 x 235 (2585mhz) stable with only 1.75 volts. I am sure it can do more but right now I am going to let it burn in at this speed.

This is my second mobile 2500+ and it blows my first one away. My first mobile 2500+ was a IQYHA 0347 TPMW from newegg.com and it would only do 2415 stable with 1.9 volts.

Anyway, the 2500+ mobile IQYHA 0352 MPMW processor from www.excaliberpc.com is the way to go if you want a nice overclocker. """

you cant get that cpu anymore.... you can get a 0351 2600+ tho which looks like a great ocer... however it is $105

thats what i said, didnt I?

[fresh prince]

What steppings are in newegg now?? Does anyone know??

I am going to buy M-2500 and I don't want to get TPMW:)

If I buy 5 processors, will I get them with the same stepping?? or maybe they are random?

Well you may be right but if you look at what ExcaliberPC is doing you will find out that the MPMWs are the most expensive ones there... So it should mean some thing isn't?

[THunDA]

thats weird..

This one is $102
AMD Mobile Athlon XP2600 Processor (Tray) (IQYHA:0348TPMW)

and this one is.. $105
AMD Mobile Athlon XP2600 Processor(Tray) (IQYHA:0351MPMW)

Its like they know the MPMW ones are better.. charging $3 more..lol

just buy one from excalibur, then youll know what your getting.

[Gautam]

I think you guys are gonna have to toss the theory of the TPMW being a bad OC'er, cuz I've got one. ;) It outdoes or matches every mobile Barton I've seen in my life. Maybe its just a sign of how much better the A64's will get?

The problem is that all these letter codes come so close to one another that its very hard do draw conclusions. Just because one given processor can do "only" 2.6GHz with 1.85v, and some other one can do 2.7GHz with the same doesn't necessarily mean that the latter is actually a worse performer. There are so many external factors at play that its very difficult to establish an accurate pattern.

The four letter codes are in turn tied to different five-letter codes, and different week numbers as well. If we could eliminate all other variables by finding two processors with the exact same stock speed, five-letter code, week number, voltage and cooling, and then see how far each could go, then we could get two relatively reliable data points, maybe. I'm almost wishing I bought 3 mobile Bartons instead of this one A64 now to figure all this out. :-/

[Gogeta_G3D]

so your A64 is TPMW, if so, we're talking about mobile bartons here, not A64. Cant compare.

[Gautam]

These four letter codes have been around since the beginning of AMD. They must have some universal meaning that can be applied to all of them. The format of the stepping codes of both the A64 and AXP are the same. They obviously follow some sort of standard.

Bah, I was just kidding anyways, hence the " ;) ".

[65stang]

i had 3 mobiles, all 0351MPMW's. Sold 2 for $130 each, the other is in my system at 12x200x1.7
