how is that weird? JIUHB indicates it's a tbred B :rolleyes:

absoluteley correct ;)

[Negative Design]

I have an AXDA 2000 DUT3C
AIRGA 022MPMW


you guy think this can be Oc'd?
I got it to 1.748 but i didnt go any further bcuz im at 61c.

He's saying its weird because a 2100 should be an aiuhb not a jiuhb.

negative desing i have a processor with a stepping something like that mine is a t-bred A 1800+ that i can clock to 2.3GHz

whoa! thats great!

i hope mine can be close to that, whats ur cooling?(include case/fans :) )

[wizardx2]

my cpu core is labeled:

absoluteley correct;)



Is it a big deal that I have a 1700-1800 stepping on a 2100+? Is it really possible to have a stepping like that; or is the labeling wrong somehow? I oc'ed it decently to 2.2 Ghz.......

[mech3]

I like the way you quoted :D , thats real strange, maybe it was mis-labeled, do you know your exact stepping bro?

That's exactly the stepping that was delivered to my house on thursday from newegg. I'm feeling gipped here, did I get an old low end TB b? I see that at least you got it to OC decently. That gives me some hope :) Cheers,

[Teh_l33t_d3wd]

I saw some other JIUHB 2100+'s at the cpu database, so I doubt it was a mix up.

[JaNoZ]

Oh joy!!!!

better post what accomplishements you got along with your core stepping and stock voltage plz.

i have an AQXCA barton @stock vcore 1.65v at 2.28GHz @169 stable @45oC, max stable fsb reached 214fsb at KT400

[Fle@B@gL@ne]

XP2600 333 FSB 2083 AIUHB

Can post and do it all at 2500MHz but no gaming yet I am on a weak cooler 35cfm 39dba 5600 on a 70mm fan (looks more like a videocard fan)

Can do it all at 2400MHz

with my cooler I run at 2275 I max temp gaming 52c on rare hot SF day I get 54c but I am 100 percent stable

[mctoush]

Is there a new stepping out for the athlon xp 2500? I had it out of my system today, and thought i'd jot down the code on it...i ended up with this:

AQZEA0327TPBW

Unless i was ****ed or something...thats different :x

[flaco337]

Barton AQXDA2800 @ 210 x 11 2315 MHz

Rock solid @ 210 but gets unstable @ 214-215 MHz. Why would this be? Vcore = 1.85 Vdimm = 2.9 Also, why would AMD CPUID and AMD CPUInfo recognize this as a 3200+? Does anyone know whats the max average o/c for these cores? I've seen people havin clocks of like 2.6 and 2.7 GHz. Are they bull$hittin or fo' reals?

BTW I stumbled across this neat-o tool over at NforcersHQ by RocketMBA called Universal AMD Tool. You dial in you cpu frequency and multiplier, and it'll give you your AMD pr for virtually any non stock setting. There is also a tool to give you assorted onfo based on your stepping code, as well as a compare thing that'll compare your setup to stock setups and give you how much of a performance percentage increase your system has when compared to different stock setups you can pick, as well as other stuff. It's prettty neat lemme see if I can get a link to work.

[LkyOldSun]

wow an aqzea?

The aqxea's haven't even made their appearance on the front page of this thread yet

[Micutzu]

It's in the first post since yesterday . I've also added AQXEA BTW .

[cbratton]

Great thread. :) Perhaps the first post could be changed to add the 400mhz bartons (ie 3200)?

Yay! the barton aqxea's finally made it to page 1!

thanks for all your work.
I'm glad I can send newb's a link to a thread that can answer their stepping ?'s (from all different forums I frequent).
Great thread!

[pat]

iv just bought a new 1700+ athlon and its got the following code: AXDA1700DUT3C T583666280233 KIUHB 0325VPMW, anyone know about this new "k" code? i have yet to get a supporting m'board so cant even boot the thing up! lol. anyone know how well this overclocks?
cheers in advance.

[Micutzu]

That is a weird stepping , usually the first letter tells the category of the CPU (J for 1700+ - 2000+ , A for over 2100+) , and the last letter the type (A for TbredA and B for TbredB) , so usually only the 3 middle letters are different . Let us know how that CPU does ;) .

[divinebadger]

i just got my barton 2500+ AQXEA0330VPMW

[biglipzit]

yeh i just got a 1600+ and the stepping is KIUHB.... i havent tried it out but i made a thread titled what happened to the bridges in this forums because from what i see amd made this almost overclocking proof with its wierd bridges.... i posted some pics it has a see through organic covering on the pcb and the bridge contacts are father apart and each contact is smaller than a pin head...

I Think I've found a new steppign for the Applebred, but I'm not sure, I cannot read this. Here are the two pics
http://www.pcanymore.net/img_big/Duron-1400.jpg
http://www.pcanymore.net/img_big/Duron-1600.jpg
the 1600er is the known MIUHB, but wtf is the 1400er?

[Micutzu]

Good find ;) .

[Beomaster]

and here the first result I've ever seen:
2133 MHz @ 1,75Vcore (16x133, more isn't available by MB)
DHD1600DLV1C T588015270108
MIUHB 0329 UPMW
the ocer who has this Duron said he closed the last L2 bridge so it looks like an TBred and WCPUID say it has 256kb Cache. Did anyone hear of anything like that?

[HideOut]

So how you guys doing with the JIUHB cores? I started reading about them and got one from gameve.com for $47 with free shipping. Its an evil toy! 2.2+ghz on air stock voltages. 1700+ is its rating from factory. I came to this site just off a google search trying to find out what kinda CPU my 1900+ AGLHA was. Thought about swapping it with my 2000+ AGOIA. Which is cooler running? I realize that 67mhz isnt much but the core is what matters right? I just need a dedicated DVD reencoding rig thats cool.

HideOut

[Micutzu]

AGHLA is a far worse steppin than the AGOIA . Beomaster where have you seen that result ? Give me a link if possible .

[Beomaster]

in the ocinside forum is a newbie with an applebred, the post was here
http://www.forum-inside.de/cgi-bin/forum/topic.cgi?forum=1&topic=7115&start=10

[Micutzu]

Ok , that's german , i'm not touching it :D j/k . The core size looks about the same size as on the Athlons , so i'd guess the extra L2 cache is there , and may be enabled . That'll be a great thing ; could you ask that person to run a benchmark or two , to see if the L2 enabling really works ?

[Beomaster]

I could ask this person, but it seems to work like a normal tbred
and a second applebred is there, MIUHB 1400 @ 12x200 with normal L2 Cache, the benches are a little bit lower than by a tbred 2300MHz.

[HideOut]

I noticed a HP computer system in the office depot the other day that was a "2300+" What is that? New chip?

hide

[Beomaster]

maybe the false multi, this must be 14x133.
And what about Baton stepping, there are a lot of german guys who say there AQXDA is better than an AQXEA. Has anybody a comparison between both CPU?
Here are the tets
With small L2 http://service.futuremark.com/compare?pcm=1487739
With enabled TBred L2 http://service.futuremark.com/compare?pcm=1490374

So, something is rolling on, here http://www.computerbase.de/news.php?id=6076&sid=2d48496b99226399b3c4b253e497be13
not every Duron works with enabled TBred cache
And this one runs 2003MHz with 1,56V and 39°C (disabled TBred L2)
DHD1400LV1C 2321348240233
MIXHB 0333 WPMW-->max was 12,5x200@1,9V 60°C

and then I found:
1400 45,5W
1600 48W
1800 53W
max 57W

wow, and thats very interesting, Duron 64L2 2142MHz faster than 2400+ and that for 40€

if 256kb L2 Cache not work, it is even possible to run your Duron with 128kb L2 Cache, here you can see wich bridge represents how muck L2 Cache http://fab51.fc2web.com/pc/palomino/athlon-e5.html
or here testet on a TBred
|||| 256kb
:||: 64kb
:||| 128kb
|||: 193kb

Has anybody here in this forum an applebred?

I belive MIUHB is better than MIXHB
and a new stepping appeared, MIUGA.

[MinJae]

"To toggle between ranges , you need to connect/cut the rightmost L3 bridge ."


I don't get it. what is "toggle between ranges"

[langers]

ive just typed my cpu's info into that uAMDtool meansioned earlier, below is a screenshot.....

it says its downgraded from a 2500+, am i right in thinkin all 2500's are bartons, and if i am, does that mean i can unlock the extra 256k l2 cache??

thanks

[Beomaster]

I don't know any AMD CPU than a Barton with 2500+. If your CPU would be an Thorton, maybe it would be possible. But this one seems to run 2500+ and was sold as 1700+, (what do I know, 2066MHz or so)
from where you get this stepping decoder?

[langers]

i used uAMDtool it was on an earlier post i think but ive just googled it and found this site...

http://www.nforcershq.com/modules.php?name=News&new_topic=21

it was the second thing down, check it our and let me know....
in a couple of days ill be gettin a nf7-s so ill take it to the limit and let u know how i get on!

[Beomaster]

OK, thanks, I'll take a look what about my TBred

[langers]

ive just tyed it for ur steppings and it says its a downgraded 2000+

[Beomaster]

It seems to be the 6th and 5th number from back in the 2nd code. Maybe this would help by bying a new CPU.

[langers]

ill let u know how far it goes 2mora wen my nf7-s gets here :D

with any luk i shud get 2.2 to 2.4 ghz but my ram mite hold me back a bit....

[Beomaster]

I see, you has an ASRock, I have a K7VT4-4x and a Problem with the RAM. It is 512MB doublebank PC3200, should work with over 200MHz, but I have the problem, if the System is warm and the FSB over 202, maybe after Restart, I do have only 256MB single Bank. If I wait till it cooles down I can start with 207MHz FSB and got a 512MB doublebank. But I never reached 208MHz or more with full RAM, it says there are only 256MB singlebank. 210MHz are stable, but for what do I buy 512MB when I do have only 256MB.
