No one with 0312 1700+?

[Marquzz]

Ordered one just now, but never heard of any overclocking results.

[T@nker-xXx]

its depend if you are a 4 9 or F

What do you mean?

[antipop]

I think it's in the second line, it's the first number or letter before the serial

The first symbol of the upper right line..... most of the people got "9", some of the 2100+ and up are "4" and generally shows better o/c..... :)

Ok, so I should get a '4' then. I've heard that 'Y' is good too?

Well "Y" are supposedly the best..... moreover - I've heard of some JIUHB 0312 "Y".... but no results yet.... :)

[T@nker-xXx]

i think the best is 4>Y>F>9

[Marquzz]

Ok, I'll probobly (hopefully:)) get it before eastern becouse the postal service doesn't deliver on hollidays :(
Will return with results, my NF7-S v2.0 is on it's way too :)

Here you go: http://lowyat.isentral.com/guides/athlonxp/ and; http://www.xbitlabs.com/news/cpu/display/20030322034857.html and finally; http://mp3.zonebg.com/cpu/cpu.php
Now once you read any of those guides you'll understand what I'm about to say.

Whether or not the 8th and 9th numbers in the 2nd line of code actually denote the original model from which your CPU (or any relabled lower speed TBred) was downgraded from, is thought to be a fallacy. Apparantly someone at AOA contacted the source of the TBred ID program (above) and the person retracted the validity of the methodology. Where I became slightly skeptical, is with the data. The number of overclock's which have corroborated the theory. The first letter of the stepping (which is the first place in the 3rd line of code) supposedly denotes the proximity of the core to the wafer center, A being the closest, then J, K, and R being the furthest from center (highlighted below). AXDA2100DUT3C 9397647280017 AIUHB0301SP1W 1999 AMD Recently TBred-B's have either been A or J.
And certainly one would concur the 3rd alphabetic (or number 1-9) also in the third line of code (following the date) has validity. A being the first production batch, for that production run, B being second, until C, and M denoting combined batches. If there is a number in that place 1-9 then this denotes re-combined batches which have falied Q&C, and been re-processed, as in the example above.
I've yet to see a Tbred-B 1700, or 2100 with an A, B, or C in the third alphabetic (following the date) of the third line of code. My 2400 has a B in that position, and my friend's 2600 has an A there. Most lower speed's TBred lately have M for combined. In so far as the 2nd line of code, the last four digits are indicative of the CPU number in the batch, lower being better. Such that in the example above it's the 17th CPU from that re-processed, re-combined, production batch. Perhaps 90% of this "code" is true except the significance of the 8th, and 9th places in the second line of code? However...

Over at ExcaliperPC they sell TBred-B's based on stepping, and date, and have included the following disclaimer; "please also do not ask us to look for 27 or 28 in the last 5 digits. We see that is just a rumor and we don't support it" regardless they got it wrong. It's the last six digits, but that's beside the point. This can stir more suspicion, then it deters. If they said nothing it be one thing, but any opportunity to sell a chip a vendor can take advantage of, they usually do. Perhaps AMD released an internal memo, requiring reseller's not to release, or advertise based on this "code"? Most of these relabled TBred's 8th, and 9th numbers are 26,27,28, even 29, and 30. So why not read the dang numbers? It may be as simple as time, althoug to estimate the stepping, you would have to read most. Anyone buying a Tbred-B 1700 or 2100 is going to consider a 2600 a great find? And I'm sure many will agree, the reason these 1700 JIUHB etc. are all reaching 2.3GHz to 2.7GHz is because they are in fact relabled from the wafer slated for higher speed TBred production. I don't need to iterate here it's common practice, and cost effective (given certain conditions) to relabel.
I would think it's logical for the person whom originally released this "inside info" to retract their statement. Because just as these relabled Tbred's are going to be short lived, so is that person's career. It's not that AMD would fear everyone rushing to buy TBred-B 1700's instead of $300 2800's or better, because the overclocker market is so miniscule perhaps 1% of total revenue. And I don't belive it's AMD's fear unscrupulous dealers will "remark" the CPU's selling them as 2600's (although it's feasable). No i think the cost to AMD would come in the form of Industrial Psychology. The Lion's share of AMD sales comes in th forms of OEM vendors, and such. A market where security, dependability, and reliability are the attributes which are most sought after. And businesses will pay more for it, ss is evident in Intel's earnings. And with Intel putting into place yet another security feature (patent 6,535,988 detects FSB overclocking, slowing the processor) they become even more attractive.

I read th articles of xbit and are they serious when they talk about the color of the die? Has it been comfirmed by numbers?

[Liquid3D]

I don't know, but I'm about to check all the CPU cores I have right now. I haven't seen enough to validate this claim, nor would I remember. But I'll let you know.
EDIT: I have an old Thunderbird 1200 that look's sort of "blueish" and it happen's to be factory unlocked. I think I'm going to throw it into my Epox today and try it! Thanx for reminding me about that little gem. I'm going to start a thread on this.

[Marquzz]

I've heard that green is the colour to choose, but I don't know the colour of mine, I'll see when it arrives. I'll post the entire stepping too.

[CCW]

ages ago someone posted about the green cpu's having a layer of something over the core and that they took it off...was one of the major OCer's i.e the green create more heat?

[bito]

Well, out of four 0308SPMW JIUHB XP1700+'s, three have had a red core and one a blueish tint.
ALL three red cores got to a minimum of 2400mhz.
The other one hit a max. of 2300 at a highish 1.75v and would not run at all with any more volts pushed through it.

red core?

Although I'm somewhat confused as to what T@nker-xXx is talking about in; "4 > Y > F > 9"...and Antipop; "...it's the first number or letter before the serial..." The serieal is the 2nd line of code and none of those figures can be there because it's the line of code whivch denotes the FSB size and is either a C = 266FSB or D = 333FSB (DDR)? I think what he intends is the first place of serial number itself, which follows the PR model number; i.e. 2400DKV3C (DKV3C = Package type, Voltage, Die temp, Cache, FSB respectively) If he is speaking of the four alphabetics following the date in the 3rd line of code; i.e. 0310SPMW the first place of this code needs to be examined. Which is why I've been asking everyone to PLEASE post their entire code; all lines. Anyway here's rough description of that particular section from iSentral.com;
"WPMW, SP1W, XPMW, XPCW, MPMW have no special meaning to the end-user, but according to the AMD Athlon XP Thoroughbred B Datasheet, the Third alphabet out of these 4 alphabets represents the number of production run/batch on a particular production date. For example, A represents the first batch of product on that week, B is the second batch, C is the third batch and so on"

COre colour has long been the best method of choosing a cpu. You should use stepping, week and the 4 letter (or digit) code as a guide, then find the best core you can from cpus filling those criteria. Its often the case that a poor core good code will be outperformed by a good core poor code cpu.

The cores in order of preference (from my own experience - ive had 30 or more AMD cpus since the tbird) are blue/white tint, purple/white tint, purple/purple tint, followed by red/purple and red/red (avoid the last 2 at all costs). Mixed colour cores (ie with combinations of the above) can either be very good or very bad. In general though id avoid them.

PiLsY.

[Liquid3D]

Hello PiLsY. I've also read Blue is the best color to get. But what do you think of this 2nd line of code theory? The 8th/9th places denoting the original PR model for the particular processor?

Do you agree in the stepping the first letter denotes the distance form the wafer center, A being closest, J next closest? Such that AIUHB would be a core cut closest from the wafer center, and a B0 core?

And in the 3rd line of code following the date; i.e. AIHUB0310SPMW 1999 AMD, that this letter (or apparantly a number can be there) this is another method of IDing a great overclocker? If so, would you have (or be able to discuss) the reason why?

[CCW]

colour of die matetrs more than stepping? only ever vhose CPU by stepping, damn!

[TodB]

Nope, it depends on the wafer quality and the production process... AMD ain't got no bucket with a colour paint in it to paint the cores accordingly :D :D :D

The wafer is the lower part of the chip and you can't see it

We're giving away a brand new 1700+ OEM T-BRED-B JIUHB 0312 DLT3C over at TPR in a little "Folding Challenge". See here (http://forums.teamphoenixrising.net/showthread.php?s=&threadid=14078) for details...

i remember a post from a while ago about a layer of coating over the chips, think it might of been JC that found it but not sure on that, it was on a greenie XP chip

[Ewok]

i would imagine that if these colours were to do with some kind of coating then the die colours would all be the same colour.

[Marquzz]

As you ca see here http://www.xtremesystems.org/forums/showthread.php?s=&threadid=11726 I got a DUT3C 0312, and it performs bad. But I guess it performs well if we have in mind that it's a DUT3C. Testing practically the it's week 11 sister right now, will return with results.

[Marquzz]

This one's even worse, it can't handle 2.2GHz with 1.75, I have to raise to 1.8V so I don't have the will to continue. Just stay away from DUT3C, period!

[Liquid3D]

That's true, when they "etch" the wafer, they do so with a photosensitive solution or liquid, which does the actual imprinting on the tabula rasa siclocon wafer. Perhaps there's a "sealent" or protective residue, responsible for the "hue" found on CPU core's.

[antipop]

That could explain it

JC posted about this a while ago but he said he hadnt seen it on brown cpu's only green, i thjink it was JC but ive had no luck so far in finding the thread, mightve got deleted in the probs we had :(

[Lunatic]

wtf ! i thougt all the new 1700+ cpu's where dlt3c :(

i found iut, its too kmme ages and ive read throught just about ewveryone of JCs posts, it was actually MickeyMouse who posted it but i was nearly right because JC was the first person to reply,
