Argh.. must.. find.. JIUHB 0252 9..
ARGH! 2,8 Ghz??? Damn, GREAT CPU! :O
Morph ,
We hate you!:D
Is that @2.2 vcore?
Don't hate me, this is more the results of low temperature and good cooling, then cpu. Don't get me wrong this cpu is great no doubt about that, but highest end AMD cpus would work even better. And thats's at 2.15V, 2.2V was worse.
No I'm only waiting for some -10 or lower temps to get that 100% oc. even if only CPUID shoot :D
omg really nice oc you got there m8 :). /me wants JIUHB but i cant find it :(. Send me one ;)
If you can run at this setting then you can get to my oc. :D
Here:
i neeeeeeeed 1700+ jiuhb
Hey guys, I've been following this thread for a while and was wondering...
I've got an 8k5a2+ motherboard and a Radeon 9700pro. The 9700 limits my FSB to about 170mhz because the Radeon doesn't like high AGP frequency.
SO... even if I get a really good 1700+ I'd be limited to 2125mhz (12.5x170).
My buddy just did the wire mod to get the low multiplier with his 2400+ and 8k5a2+ ... would it be possible to do a wire mod to give the high multipliers?
That way I could get a 'good' 1700+ to run at 15x166 or 14x166.... just a thought.
R9700 is good for about 195-200 FSB on 8k3a which is almost the same as 8k5a, for unlocking you need to cut the last L3 bridge, and if you want to switch back you can do mobo trick and solder 100 ohm resistor to pin AJ27 and ground on socket A (back of the mobo), you can then make like a jumper to switch between up to 12.5 MP and above 12.5 MPs
I did just that
morphling1, go get urself some LN2 and spank that CPU to 3 ghz :]
:D
I realy don't care too much about those 30minutes or shorter tries. I'm interested only in something that I can keep stable 24/7 overclocked and stressed. And for me that's only water cooling or phase change. So my next project would be to combine this two methods with high efficency water chiller, because I realy like the idea of temp controled water chilling where every major heats source is cooled.
Also I find out I was also way off with my heat output calculations. I appologise to those I tried to persuade :)
I find the realy good html heat calcutor refreshed regulary from cpu spec sheets and practicaly tested in controled enviroment, definetly bookmark material, also don't forget that 88% of max heat output, because that is aprox. what the most stressful programs can load cpu.
http://www.benchtest.com/calc.html
So 2.7 GHz 2.2V outputs (88%) 135W which is very believable.
Of course we musn't forget to use the real Vcore because, when loading no Vcore will stay at bios settings.
Ur right about the LN2 thing, thoug i think it would be nice to be a owner of a AMD 1700+ @ 3.0+ ghz, 24/7 or 30 min, §§§§ the same, I think it's still s quite nice feeling :)Quote:

I don't think that there is too many AMD chips out there that ever has been over 3.0 ghz.
Don't mention it ;)Quote:

I thought that If I give ya that same link you'll see what was I talking about, but somehow forgot that thread and just came back to see what you've written :D :toast:
That's funny... both me and my buddy have a 8k5a2+. He has a AIW 9700pro and I have the 9700pro... both video cards chock on anything close to 75mhz AGP.
We are both using retail ATI cards... could this be the problem?

wish me luck guys !! ... a local store here just e-mailed me they now got JIUHB 0302 ..... ii would've bought 2 of those 0251s but i guess i'll try out 1 of these JIUHB 0302 first .
I earlyer calculate with the same formula as the benchtest site. So i don't see how you got 135W?Quote:

Of course we musn't forget to use the real Vcore because, when loading no Vcore will stay at bios settings.
The formula is
Overclocked Watts = Default Watts * (Overclocked Mhz \ Default Mhz) * (Overclocked Vcore \ Default Vcore)²
That would be...
59.8*(2700/1467)*(2.2/1.6)² = 208.0847Watts 100% and 88% = ~183Watts
AMD says the cpu radiates 59.8W max at defualt settings... old 1700+ Tbred A would radiate ~49W max.
So explaine yourself
Hmm, if you got an 2600+ then 135W(88%) would be right but we were talking about 1700+ here and then its not the same thing!
[edit] i have now started a own thread about wattage calculations http://www.xtremesystems.org/forums/...?threadid=8798 write some reponse
Tedi - are those 03's 9, 4, or Y's?
I am interested in one of them, or the store where you bought them from.. 8-)
i don't know yet .... i'll be getting them tomorrow ..... and uhh i live in the philippines. which is close to malaysia (AMD) and intel makes CPUs here as well. as far as i can tell the salesperson e-mailed me they already have the t-bred B JIUHB 0302 ..... i was looking for d 0251 that morphling has.
It will be interesting to see what 0302s do. Let us know asap!Quote:

how can i know if my is Y, 9 or 4 ?
Look at the last CPU I posted a pic of...at the black label. It says AXDA1700DUT3C...to the right of that is a 9. That chip is a 9....though I'm not sure how critical this is :)
Edit: morphling1,
2.8GHz is amazing :)
You're so close to a 100% OC :D
I can't wait to get this thing under my waterblock now.....I hope its anything like urs ;)
http://www.noone.hpg.com.br/proc.JPG
Its 9, right?
How bad/good this is? anyone know?
crank it up so we'll know how JIUGB steppings do
Yeah, we really want to know, Lot's of people in Sweden wanting to know too!
Edit: When do I stop beeing a new member? ;)
9 means nothing to any1 who isn't guessing :)
JIUGB is interesting tho. Crank it up indeed :D
Edit:
I will try to test my JIUCB 0251 tonight. The other 4 1700+'s are scheduled to arrive tomorrow according to FedEx ;)
