Help find XP2000+ Thoroughbred B

[jdurbin]

Thanks to whomever gave me this lead:

http://www.overclockers.com/tips00173/

Does anyone know a good reseller who is selling the Thoroughbred B (preferably) or the Thoroughbred A instead of the Palomino? Googlegear has the Palomino.

Also, does anyone know how dramatic the difference will actually be in terms of overclocking potential?

Thanks in advance!

We are ALL waiting for TBred-Bs at speeds below XP2400+... they AIN'T out just yet... a couple more weeks away

I can get some 1700's in t-bred cores...unfortunately that's the only speed i've seen so far, if you want one let me know I can get you one for about $65 plus shipping.(probably not the best deal around)

Those are TBred-A's... B's are not released to the sellers yet. If you're sure you see B's for sale, please post their OPN (part number)... the seller should have this info.
Thanks

Just a followup from another forum I frequent:

Dear Valued AMD Customer,

Thank you for contacting AMD's Technical Service Center.

All of our thoroughbred processors that we are currently manufacturing
are Rev B.

We appreciate your business.

question!

neat! key words being..that we are manufacturing, right? versus what they know is for sale in the retail channel

Just one more comment from amdmb.com forums regarding why the hype over TBred-Bs:

it is THEORY that they should overclock up to 300MHZ better than a A..but put it this way, if an A tbred 1700 for example will overclock 400 to 450 MHZ better than stock settings, do you really believe using that as a measure that a 1700B will overclock 700-750 MHZ better than stock? i don't buy it..but, that's what's creating the hype around these.

they have 9 layers versus 8 from what i recall..allowing for more stability of the chip i'm told..and they also should have a default voltage of 1.6 i think it is, rather than 1.5 of tbred A's.

I have an XP1800+ TBred-A, AIUGA, 0241MPM. I'm running it completely stable on air at 2.0gHz... an overclock of 467mHz, and I don't think I'm really pushing it. See attached.

i'll look into the revision tomorrow

Do you all agree that the "retail box" CPUs are most likely Palominos?

Also, is the difference between Bs and As greater than the difference between As and Palominos? In other words, since I am not a power user/tweaker should I just be satisfied with a Palomino or T'bred A?

Thanks for everyone's feedback!

Couple things to ponder:
1. If you're in N Am, check out Newegg.com as they are expilicit in their description whether you are getting a Palomino vs TBred:
http://www.newegg.com/app/ViewProduc...tby=14&order=1
2. Usually, if the vendor is halfway accurate, the boxed sets of Palominos will have a part number like "AXP2100BOX"... the "AXP" portion indicating Palomino. A TBred box number would be like "AXDA2200BOX" with the "AXDA" indicating TBred.
3. You asked whether the difference between TBredA and TBredB will be greater than Palomino and TBredA... no one truly knows because it is all speculation for right now... no one (outside of AMD Corp.) has done any testing on TBredB lower than 2400+ because none have yet reached the marketplace.

My "speculation" is that there is a greater difference between Pally and TBredA then between A and B. I have an XP1800+ TBredA AIUGA stepping... it runs rock steady at 2.0gHz at 1.80vcore, aircooled. It could be pushed higher (already at 466mHz OC). I don't expect you'll see a TBredB 1800 going an additional 400-500mHz on top of that.

For a non-overclocked, the TBred A's would be better than the Pallys in that they run at a lower voltage for an equivelent speed, and will be easier to cool (except the XP2200+ TBredA, which runs hot). My 1800's default vcore is 1.50. They also offer some design advantages and support some extra instructions (I'm going off memory here, so I don't want to misspeak with any detail)

The Tbred B's should reach the marketplace in another couple weeks if you can wait. I expect when they do, the TBred A prices will drop further, so you can pretty much take your pick.

Having said all that, you can get a TBredA 1800+ at newegg.com for less than $70US (OEM, no HS/fan), newegg will sell you a 1 year warranty for less than $10... and you can potentially run that cpu at XP2400+ speeds (2000mHz)... pretty good deal!

Thank you very much for the post. I am going for the 2000+ and I was planning on going out to CA on the 17th of the month to build with a buddy. I guess I can postpone my trip for a few weeks, just build one of the PCs with the mobo he is giving me in order to learn and then do the real one when I get back or just be satisfied with a Palomino. I am doing some power supply and HSF research now. I can always spend a little more on a better power supply as insurance. Hmmmm, decisions decisions. Thanks for help.
