its got RIRGA stepping.. never heard of it before and made on the 35th week of 02.

its prolli abit of a old one, its that brown colour too :/ the box it came in was green tho.

I will benchmark it soon, all the l1 bridges are intact :)

Yeah I just got a week 40 AIUGA TBred A 1800 yesturday, but I'm a bit dissapointed.

It does 1.85 GHz at 1.55v, but cant get it stable at 1.9 GHz with 1.75v and a Volcano 9 or a GW TAK-68.

AIUGA and TBredB?

Heat may be your primary concern, at that sort of setting, it's around 90~100W of heat output.

The TAK-68 is not going to handle that. Not sure about the V9 though.

I thought the last letter of the stepping was the revision :confused:

Anyway I ordered one from Alex on Thursday so hopefull it should be here on Monday (I hope) :D

90-100W no way, it's about 10ºC cooler than my Palamino 2100 at the same speed.

Also, both coolers are lapped, and the TAK-68 is 2ºC cooler than the V9 at the same noise level. The V9 at Delta fan noise level only just keeps up with the TAK-68. From the reviews I've seen the TAK-68 is one of the best coolers for it's noise output, and it seems that way in my system. I'm thinking because it has a really solid aluminium core. I'm going to mod it next week and interference fit a copper core right through the middle. That should make it one of the best coolers.

RIRGA? are you sure it's not AIRGA?

Hans

http://newstuff.orcon.net.nz/wCalc.html

An XP-1800+ @ 1.9GHz, 1.75V has a max output of 86W.

An XP-1800+ @ 2.0GHz, 1.775V has a max output of 93W.

If you push the V/Core to 1.85V then it will break the 100W mark.

if the codes is AIUGA it cant be a Tbred B
the last letter of the stepping denotes wether its a B or an A
AIUGB now that would be a B stepping

why dont ppl buy real good coolers?
like SK-6 the top end alphas etc
i wouldnt touch a thermaltake cooler ever, and aluminium is a big no no , pure copper all the way :)

So why are you recommending the Alpha, you would be talking about the 8045 which only has a copper base

I'm using an AGOIA 0213 RPDW now
It's XP1600+(133*10.5) palomino
and it is oc to xp2200+ (170*10.5)
According to MBM5
cpu temp:45 celcuis
but I'm not using good cooling system
it's just a normal 6*6cm heatsink with a 5000rpm fan
it's quiet acceptable
Using the same cpu as I
my roommate have a lian li pc-12 aluminum case
his cpu temp is only 39 degrees

btw
Does anyone get a Tbred b. xp1700+
Many of us in Taiwan got one....thohgh i didn't
The average performance is quiet impressive
@1.6V oc to 2400+(2G)
@1.95V oc to 2.2G

Yeah I'm waiting for the TBred-B to get here (apart from 2400+ and higher which are already here).

I'm sure there will be a TBred-C, AMD need to keep refining the process to get more 2800+'s (higher yeilds) coming out of the FAB.

I think there's a difference between refining the process and redesigning the chip...... the T-breb B has and extra layer in it as opposed to the T-bred A

I'm assuming they try different layers etc while refining the process. I think this because of all the cahnges on different steppings like sometimes:
1, Capacitors and resistors are on the top of the CPU, and sometimes on the bottom, or just moved around.
2, They always change the cores, ie TBird has less transistors than Palamino which has less than TBred. I'm guess they are always trying new changes.
3, A die shrink is usually carried out in conjunction with a new shape, not just a smaller core. Take the shape of a Palimino and a TBred-A, and then the TBred-B is different again.

All these changes, and yet clock for clock all the XP's would perform on par even (give or take a tiny amount) though they are the same CPU.

I don't know a heck of alot here, but what do you think the difference is between a P4 A1,B1 and C1 stepping?

i just got back from Taiwan
picked up one of those 0.13mm 1700+
as I really have no money, i shoved it on my KT133 Asus A7V. and it works wonder at 1.4v @ 12.5 x 100
sure i can raise FSB, but i don't feel like taking risk of destroying my hdd data etc.

Anyways, the main point of my article is where would i be able to find conductive pen ?

http://www.beachlink.com/candjac/index.htm

according to that webpage, I should be able to unlock my Tbred. so it does 18.5 x 100 = 1850 .

shouldn't be too hard for my cpu =)

please advise where would i be able to get those conductive pen ?

thanks!

Most TBred-s are factory unlocked like mine, I'm not sure if ther are any locked ones actually so you should be able to change your multiplier now.

And as you only have a KT133 chipset I don't think you will find an 18.5 multiplier, you will only have 12.5x. Also to go above 12.5x you would have to unlock the cut L4 bridge, and cut (thats right, with a sharp knife) the other L4 bridge. Then all your multipliers below 12.x wont work.

You will not corrupt data at 110FSB, it's not really high enough even though you only have a PCI divisor ratio of 3. You will also find you won't be able to get much past 113FSB with the KT133 chipset.

so i just went into guan-hwa..

and bought one.

usually, the shopkeepers only keeps the
"good batch" to their preferred customers.
since i don't go back very often, i doubt
my one's any good. still, i'm not overclocking. and just want a cheap0's
upgrade to my already aging system.

it does xvid/ogg compression nice and
fast now ;)

my t-bred 1800 is a shocker, its running at xp2000 speed as happy as lary but when i push the milti up from 13X to 14X the bios claims its running at 5X :mad: so my cpu only runs at 600 odd mhz, i confirmd this in windows too.

My rig doesnt like 166 fsb either, i think its my ram even tho its running at 133.

I hope it dies and i can get a replacement one! (i wont kill it tho)

With all my oc's i dont let the temp abouve 45*C it get abit hard especially when im running my fans on low and my water temps start creeping up.

CPU and water temps have around a 10*C diference after running my comp for 24+ hrs under full load:/

If i run my comp for only 1 hour and do intence benchmarking the diference is only ~2 or so *C

(i take my water temps after it has been coold by the rad)

You can't access the 13x or higher unless you change the two L4 bridges around, well it was the L4's for the Palimino.

Yep, TBred-B is a new stepping, have a look here for some "What is a CPU stepping?
http://www.anandtech.com/guides/viewfaq.html?i=6

Thought I'd already pointed this out to you.

Also XP will not be phased out just yet acording to AMD,
XP's/Barton will replace Durons for another year or two, althogh Duron may still hang around until 2004, I wonder how cheap they can become?
Hammers will become the high end of the market.

Here's (http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_608,00.html) AMD's CPU roadmap.

Good point Mird, after reading it again (more slowly) I am wrong, iIf it ends in B it's a B, and ends in A it's an A as Blitzkrieg has told us. Actually I don't know how I missed it, it's only plastered all over the page 100 times.

There is someone in the www.overclocker.com CPU database with an XP2600+ (obviously a TBred-B) overclocked to 2310MHz with 1.7v and a code of AIUGA but he must have written it down wrong.

But it's interesting that there seems to be two different knids of TBred-B, and one of them just doesn't perform like the other.

I know what a stepping is
i was meaning there wont(i highly doubt it)
tbred C, B will be the end of the line
and the tbred will slowly die out i think and be replaced with bartons only, tho i dont think it will happen till the end of the year
also the first tbreb Bs that came out below the 2100+ were not very good at all
they oc'ed worse than the best A stepping
tho the latest JIUHB has been breaking 2ghz quite often so things are looking good.
all XPs are the same architecture
TBredA was a pure shrink of the palamino core thats it
TbredB they added a 7th metal layer to reduce capacitance or electromigration , something like that, something complicated, also it went from 80million transistors with A to 84 with B
improved layout i think. and now its just the steppings to work out bugs and improve the critical speed paths
