hehe, the CPU have over 200W :flame:Quote:

Is the stock voltage 1.5 or 1.65?
1700+ "B" = 1.6V ;)
D'oh!:D
Well, thats
[(2700/1466.666...) x ((2.2/1.6)^2)] x 49.4 = 172W
Unless I'm mistaken about the Maximum Power Dissipation?

Well, I finally was able to find AMD's white papers, :rolleyes: and its
[(2700/1466.666...) x ((2.2/1.6)^2)] x 59.7 = 208W
And roughly
[X(208 - 30C)] = 50
Which equates to at least a .03 C/W Waterblock!!

You guys need to drop all those radiate heat calculators or similar and take a look at AMD specs sheets.
Heat output is directly dependable on voltage increase, that is correct but that does not hold any more for frequency increase, heat output just barely increase with the same voltage.
Ok lets do a little calculations, based on AMD specs for tbred B
1700+ 1.6V 1466 MHz max heat output 59.8W
2200+ 1.6V 1800 MHz max heat output 62.8W
so 333 MHz increase in frequency produce 3W of heat. So 1 MHz of frequency add 0.009W
Overclocking to 2700 MHz at 1.6V add another 11.10W + original 59.8W = 70.9W
Overvolting to 2.2V increases heat output linear by 37.5%
So my cpu at 2700 MHz and 2.2 V produce 97.48W and this is tha ball park we're talking about.
Craig, judging by the picture of Barton, it's only a little longer but the same width as tbred, so I won't have to change the design for it
Somehow I'm always the last to know. Thanks for the heads up:)Quote:

That's not exactly right..... if you look at document 25175 from AMD datasheets you'll see that 2000+/1.667GHz TbredB pulls out 61.3W of heat and 2400+/2.000GHz TbredB puls out 65.3W.... now that's 4W of heat, not 3..... but it's not as simple as that....Quote:

so 333 MHz increase in frequency produce 3W of heat. So 1 MHz of frequency add 0.009W
Those CPUs are NOT exactly equal.... another example - in the samo datasheet there are two types of 2000+ TbredAs, they run with different Vcore - 1.6V vs 1.65V but they are labeled to pull out the exact same amount of heat....
And believe me - one 1467MHz CPU won't "add" just 11W to its power consumption when overclocked 1300MHz more to 2700MHz.... it's not possible...
This is a semi-conductor technology, not maths.....
You're right it's not math, but it it holds much better then linear increase in speed and heat output
skip 2400+
Lets take a look at 2600+
2133 MHz 1,65V 68.3W
Compared to 1800 MHz 2200+ that's 333MHz increase in frequency which like I said adds 3W
So 62.8+3=65.8 now here we also have increase in voltage so 65.8*1.65/1.6 = 67.85W so only 0.5 W off the correct mark
So if I'm of by lets say 5W at 2700MHz 2.2W that's nothing compared to 186W calculation right :)
Hey, live and learn, right?Quote:

But of course :toast:

I think yours and cathars' blocks are doing pretty close.. but mines gonna make them wimper 8-)
Just gotta procure the materials.. stupid hobby shops in alberta.. 8-/

Can't wait STEvil :toast:
I should mention that my pump is likely going to have a slight affect on the outcome.. being able to put forward some serious flow rate and psi for under $100 CDN.
I will have stuff up as soon as I possibly can, but my time to work on this stuff is a bit limited right now.. 8-/
I've got a 450W Allied coming. Have 1 runnin my Duallie & its sweet. Adjustable pots & only $46 shipped :)
I don't think I'll buy another Antec PS...that thing died in only about 6-8 months :(
Now I'm getting anxious ;)
Somebody posted a pic explaining the different steppings, but i cann ot seem to find it ? anyway if anyone knows what the manufacturing code for a t-bred 11700 or has that diagram can they please let me know!
ta
A 1700+ Tbred B is AXDA1700DUT3C :)
Ordered 2 of these bad boys from New Egg last night.
Should be here early next week. Hope I see some similiar reesults with em :)
Peace

I'm gonna say it just one more:Quote:

Mfr code: AX1700DMT3C
Athlon XP 1700+ 1.47Ghz SoA
Mfr code: AXDA1700DLT3C
Any idea if either of these could be a t-bred?
AX1700DMT3C = Pallie
AXDA1700DLT3C = Tbred A
AXDA1700DUT3C = Tbred B
Mind you AXDA1700DLT3C is what Newegg advertised, yet they shipped a AXDA1700DUT3C :)
Thanks N8 :D whats the diff between and a&b?Quote:

For me? About 400MHz of OC ;)
The B being the better choice of course :)
geee that is some difference!Quote:

I can only hope they all clock so well...got 4 more comin :)
