Newegg selling 1700+ TBred "B?" Interesting info here :)

[Xeon24]

OK, I think we may have a B revision here. I can't be sure, but this could point towards it... In an anandtech review recently, it stated that AMD is moving completely to the B revision TBreds ( or so I heard, didn't read), and I'm looking at the PDF from AMD showing the latest tbred models:

Wanting you guys opinions on this one

Here are the latest models and operating voltages below:

Athlon XP 1700+(Model AXDA1700DLT3C) 1.50Volts
Athlon XP 1800+(Model AXDA1800DLT3C) 1.50Volts
Athlon XP 1900+(Model AXDA1900DLT3C) 1.50Volts
Athlon XP 2000+(Model AXDA2000DKT3C) 1.65Volts *
Athlon XP 2000+(Model AXDA2000DUT3C) 1.6Volts
Athlon XP 2100+(Model AXDA2100DUT3C) 1.6Volts
Athlon XP 2200+(Model AXDA2200DKV3C) 1.65V
Athlon XP 2200+(Model AXDA2200DUV3C) 1.6V


Ok, ok, not going through the last few models

The 1700+ listed here is the one that can be found at www.newegg.com. It's default voltage is 1.5V.

The 1700+, 1800+, and 1900+ here share almost the same model number, for the exception of the name, and all use 1.5V. Notice the voltage jump required for the first XP 2000+ listed?. This is listed as a .13 chip, while the 2nd one uses only 1.6v (showing a later revision). It should not take 1.5V to go from 1600 to 1667MHz, signaling a possible new revision for the lower versions, more specifically, the B revision, or at the very least, a new better A revision?

I couldn't tell you for sure that this means that we are seeing B versions, but the above is something to look at.

I am willing to bet that they are remarked Tbred-A procs. Maybe after the first batch of tbreds are gone will they use tbred-B for lower speeds.

 

[Killrose]

Well they all are AXDA cores right? So they are of the same process. Maybe they are all "A" and not the newer "B" series. Now if you had a 2400+ in that list with the AXDA core, that would confirm "B" revision T-Bred.

 

[techfuzz]

My Athlon XP 2400+ that I am holding in my hand at this moment reads:
AXDA2400DKV3C

I had the same hunch about the Rev. B's for the rest of the XP line. I didn't think the lower XP lines would be appearing any time soon in T-bred form because of the abundance of regular Pal cores and AMD's need to supply the new clock speeds of 2400+ and greater, but it looks like they are starting to pop-up. This makes sense as AMD announced its plans to produce all of its future XP cores (including older clock speeds) in T-bred form.

I think there is a good chance all of these new T-bred XP's are in fact Rev. B for the simple fact that no Rev. A's were ever produced for the lower clocked XP's. If you can find a lower XP model that was never produced as a T-bred, and you can determine that it is definitely a T-bred, I think it'll definitely be a Rev. B core. I don't think AMD made too many Rev. A cores, just enough to fill their supply for their announced T-bred speeds (2000+ and above?) so I seriously doubt they had enough to back-fill supply for the lower existing XP models. IIRC they only announced their intent to replace all XP models with the T-bred core after they had "perfected" their T-bred core with Rev. B cores.

If these new 1700+'s are in fact T-bred cores, I'll be jumping on one ASAP with the guesstimation that they will be Rev. B cores

Boy if this is true, the AMD bang for the buck award just got better. For $54 shipped the 1600+ AGOIA @ 1800MHz just about has to be the sweetest deal ever. 1/3 the price of the discontinued 1.6a, and almost as fast. Now those few lucky people who are getting 2.6-2.7GHz out of the "bargain" P4's are still faster than an 1800MHz AMD, but definately not worth the extra $100 wallet bite. Now for $78 you can get a true 2.1-2.2GHz with a 1700+ thoroughbred revision "B"? Half the price and faster is even better than 1/3 the price and almost as fast.

I just ordered one of the 1700+'s from Newegg for $75 beaners. I seriously doubt they remarked rev. A T-bred's as that would probably cost more than just fabbing new ones and would entail them recalling a significant amount of existing inventory from the floor-room at vendors across the country. I agree that buying a 2100+ or 2200+ T-bred runs the risk of being a Rev. A core, but chances are AMD probably stopped fabbing Rev. A once they met the initial demand upon launching the T-bred knowing that the Rev. A models were seriously flawed.

In any case, there's only one way to find out, and since there weren't any 1700+ T-bred's available until a few days ago, I'm taking the chance its a Rev. B core. It should be at my place on Wednesday, so I'll try and burn the midnight oil to get results by Thursday. Even if I don't get a chance to tweak and OC, I'll at least be able to run its CPUID to determine its revision. IIRC thats the only way to tell which revision it is, as all existing Rev. A and new Rev. B T-bred's have model numbers that begin with AXDA.

What would be more helpful is someone with a 2400+ confirmed Rev. B and a 2200+ Rev. A listing their stepping and week number to compare vs. these 1700+ T-bred's.

Even if the 1700+ I ordered is a Rev. B, I won't be able to test it to its fullest with my somewhat dated rig (I'm still running pc2100 on a KT266A). I'll leave that to you guys if I can confirm it is a Rev. B

[pillage2001]

techfuzz, you wanna do a CPUid for us to see what stepping rev is it??

Techfuzz, do you mind listing your Stepping and Date so I can compare it to the 1700+ when it gets in? Also if anyone has a 2200+ Rev. A sitting around, listing its stepping and fab date would be great too.

TIA,

Spaces added for clarity

AXD A 1700 D L T 3 C
AXD A 1800 D L T 3 C
AXD A 1900 D L T 3 C
AXD A 2000 D K T 3 C
AXD A 2100 D U T 3 C
AXD A 2200 D K V 3 C
AXD A 2200 D U V 3 C



I just wanted to chime in here. The numbers above do not contain the processor's stepping. The first three letters are the Family Architecture. 'AXD' represents the model 8 cores known as Thoroughbred. The 'A' in that follows says that this CPU is meant for desktop systems. The next four digits represents the model number.

'D' in the fourth column represents the package type, OPGA. The next letter, either L, K, or U represents the default voltage for the processor, L is 1.50, K is 1.65, and U is 1.60. In the sixth column, 'T' and 'V' give the maximum rated temperature, T being 90 C and V being 85 C.

The '3' tells the amount of L2 cache, 256KB. Finally the 'C' gives us the FSB for the processor, 266MHz.

There is no way that these numbers can be interpreted to see if the core will be revision A or B. The only way to tell is to CPUID it. The ID for a revision A CPU is 680. The ID for rev. B isn't listed on AMD.com, that I can see, but is obviously will not be 680. From the beginning of the T'bred rev. A cores, voltages between 1.5 and 1.65 were planned to be used, so voltage level isn't conclusive. As for the steppings, the AIRCA stepping was used with rev. A, while AIUAB is a rev. B core. Good luck with your new processor. Peace.

As soon as I get my PC built tonight I will most definitely post my results here for you guys. I just got my motherboard today, just got home from work, and going to start building it right now.

Can anybody decipher his results??

 

[pillage2001]

Here's an interesting read.

 

[chizow]

D'oh! That link pillage posted shot down my theory......

Maybe I'll get lucky and get a 2400+ instead of the 1700+ I ordered lol

It should be in tomorrow, so I'll update then.

Good luck dude. I wanted so much for your theory to be true.

Hehe well it may be true in a month or two.....it looks like I OC'd my crystal ball a bit too much

Have you gotten your Xp1700? I'm waiting for results.

 

[rogue1979]

Well guys? Was it a revision B or not? How high did it overclock! If this cpu has the same capability as the 2400+, this could be the cheapest and best overclock of all time!

 

[chizow]

Hehe no, I haven't gotten it yet. It'll be at my doorstep tomorrow afternoon, with the standard NewEgg 2 day service. After reading the links Pillage posted, I don't want to get anyone's hopes up, as I doubt it'll be a Rev. B chip. Best I can hope for is a late stepping Rev. A, which I might be able to push to ~1.8-2.0 gigs, which still would be a nice OC, but not anywhere close to what the Rev. B's will be doing.

Chiz

 

[N8]

I have 1 waiting for me @ fedex. If I get a chance I'll pick it up tonight and slap it in...I'll try to remember to come back here w/ the results as I don't frequent these forums so much anymore

 

[N8]

Here's a pic of the chip I got. I'm pretty sure its a Tbred-A. I think I'll have time tonight to test her out:

N8's 1700+ Tbred

 

[lsman]

its a "A", "B" will end with AIUAB (B at last character) and why not product some more chips (with A) as A is using a smaller size.

 

[dannybin1742]

how much was the chip? if it is like $60-70 and it can hit 2ghz, i might consider getting one.

 

[chizow]

I picked one up from Newegg on Monday for $75 shipped, and the price hasn't changed since then. Its at my place now, but I'm stuck at work Some guy posted on the Newegg reviews that he hit 1.99 ghz stable...which is a very nice OC for $75. 1600+ is up to $56, and 1700+ is only $7 less....

Chiz

 

[chizow]

Just got the 1700+ Tbred and its exactly the same stepping as N8's. I'd post a linky to the pic, but its kinda pointless since the only difference is the last serial # is a 9 instead of his 6.

AXDA1700DLT3C
AIRGA Week 32

I'm gonna shut everything down and pop her in as soon as I find that linky on how to open the upper multis.....I think its the last L5 bridge, but I better double-check

Chiz

Edit Update: Unlocked, shutting down to pop it in...I got an Alpha Pal8045 HSF, so this is the most un-fun part of swapping out cpus :frown:
