Replacing all the CPU's in my folders :)
COOL
N8
You say you ordered 4 more from Newegg? When did you get the JIUHB 52 , or when did you order it?
Ordered it last week, got it wednesday. Ordered the other 4 as soon as I saw how this OC'd...no idea whether they'll come from the same batch or not :)
Tod 2600+ 2133MHz cpu add just 8.5 W from 1466MHz, and that with running 0.05V higher at 1.6V it would add 8.25W that in 666MHz overclock times 2 that more than my overclock, and it would hypoteticaly add 16.5W you can increase that to 20W if you want but I'm still only 10W off at the most.Quote:

2700 MHz cpu at 1.6V based on same design would not produce more then 80W.
N8 I'm just scared how your folding numbers will go up with so many machines running 2.3 or more GHz folding non-stop, and not eve mention that you wouldn't get one high end cpu for that money :D :D
If that little cpu isn't a direct gift for overclockers from AMD, I don't know what is.
Voltage doesnt add linear so 186W may very well be correct. Nice oc morphling1, just ordered me a 1700+ JIUGB 0251. Hope I just get that prometeia soon and we might see 3GHz+ :banana:
When me and a friend LN2-cooled a duron 600 to 1521MHz we used two powersupplies in paralell to get sufficient current, one 2x300W server redundant powersupply and one enermax 431W. We were above 3V with it and the cpu radiated 248W. We couldnt get over 2,5Vcore with one powersupply so i think its safe to say that the cpu consumes more wattage than u think morphling ;)
I think got that a little wrong, of course voltage add power linear. And as for total cpu output forget that 186W how do you think that some air coolers would handle that kind of load ? Because 2,2V and 2.5G was seen on air.
But forget that I don't wanna argue about that, I just know that this cpu just don't output more then 100W of heat even at 2.2V 2700 MHz, because my heatercore don't have any more problem cooling the water as it was with old palomino maybe even less. And that tell everything. Do you even have the idea what kind of heat flux would that be if cpu from 85mm2 would outputs 186W, no way in the world my block (or any other) is that good to keep cpu temps ~20°C above ambient with one 1000 l/h aquarium pump.
As for PSU I'm just testing them for our local hw site. 300W Enhance PSU didn't complain one bit when I tested at 2.1V 2500MHz together with 2 cdroms 4x120mm full speed fans (each 5W) fans one 80GB hdd, with 2hours of Tost loading
To bad BillA doesn't visit this forums :) I'm sure he would laugh at those numbers.
Fantastic! Very cool oc! ;)
Nice indeed.
Anybody know how the JIUGB chip clocks?
Cant get my hands on a HB in sweden jet :/
I didnt mean that the duron we overclocked radiated 248W, no way near, but the heatoutput DOESN'T add upp linearly (spellcheck plz?). When u increase the vcore the current also increases, thats why the heatoutput isnt linear against the vcore increase.
Xizten: www.overclockers.se has xp1700+ JIUGB, in case ur interested :)
i know, but i dont want to but it and found out that it sucks :) And i havn't got money for a 8rda+ jet :/Quote:

Yes of course the current is in the equation too, but who knows how it changes, it doesn't necesary mean it increases too. I just looked at amd tech docs. and go from there and everything pretty much fits together the way I calculate.
Some computer engineer here, we need help :)
It should be 59.8*(2700/1467)*(2.2/1.6)² = ~208Watts
But that’s impossible because it would mean that an IRC friend would aircool an 117W processor with a old cooler master heatsink. That’s an all aluminium version.
So I'm really wondering how to calculate this.
Edit: morph cant u send a message på BillA? we really need to find out the real way to calculat how much the cpu outputs.
Theoretically the CPU should act as a resistive impedance , so you can calculate the power with the Power = (Voltage) squared divided by Impedance . Of course the impedance vill vary with the temperature , and it's not perfectly linear with the voltage , but it's a good approximation .
The other thing is that the impedance will also vary with the frequency (higher frequency = lower impedance) , but this isn't a linear variation either .
The 248W figure seems pretty belivable to me , the voltage was almost 2 times higher (wich would mean 4 times more power) and the CPU clock was almost 3 times the original one , so 3-4 times more power dissipated would look belivable .
Stole the Allied 450W outta my duallie for now(don't worry folders, replaced it w/ a temp pos PS) & I'm priming right now @ 2437MHz, 1.95v :)
Wife away for the weekend, couldn't stand to let it sit all dern weekend! ;)
Hey guys, I don't upgrade much, but I decided to join the 1700+ t-bred "b" fun. Nothing compared to what the guys here get, but I'm proud of it.
Lookin good! What stepping/week is that 1? :)
& what are your system specs? ;)
Nice.....only 1.7v & crucial PC2100 memory :)
Very impressive :D
That's why I'm so surprised. I need an 8RDA+ with the PCI/AGP fsb lock
Why does it suck? The stepping or? JIUCB is the worst of the J-breds i've heard, and JIUHB the best. But i dont think the difference between JIUGB and JIUHB is very large.Quote:

I got my 1700+ Jiucb yesterday, up and running today, now @ 1900. My mobo isn't the best one, Msi Kt3-Ultra-Aru, but I'm gonna clock more ;)
It can differ alot between one chip to another, you can get a really good Jiucb and a really bad Jiuhb too, even though Jiuhb's are the best.Quote:

Mine is good, I am on 2,2ghz with the JIUCB stepping but with 1,950Vcore (210x10,5). Im happy with allmost a 800mhz oc
