XP 1800+ Tbred B in da house

This afternoon, I went to the store in Germany where I buy most of my PC stuff.
I asked if they received some new AMD's. "Just came in", said the boss. I asked for a 1800+, to see if by any luck, it was a Tbred B.
It was the only one they had, I didn't check the other ones.
Checked the cpu's first line : DUT3C it said, week 50.
I wasn't 100% sure about it but as far as I remember, the TBred's A had DLT3C in the first line.
Took the cpu back home and installed it in my 8k5a2+.
Went in the bios and default Vcore was 1.60V. I knew the TBred's A had 1.50V default and the 2400+ and up had 1.65V.
I checked the stepping here and YES, it's a Tbred B.

Here's the full spec :

AXDA1800DUT3C
JIUCB0250VPJW
9251356260281
1999 AMD

Right now, it's running Prime95 at 1805Mhz, default voltage. Not bad for a cheap 1800+. :banana:
Board is Epox 8k5a2+, cooler is Swiftech 462A with Panaflo L1A.
I'll keep you guys updated on how high this sucker can go.

Indeed a Tbred B. Now start clocking it! ;)

Seriously, I'd love to hear how it clocks. :)

In the stepping JIUCB the B is the revision code. Last letter in stepping is revision. So yes you got a B for sure. Grats and keep us posted.:toast:

Also a week 50. So week 50 is about when they started the B's probably.I dont believe the lower speed tbred B's will do good for the first few months because they are just the chips that didnt make the xp2400 cut. The ones to watch out for will be the mobile Tbred B's on ebay. They will most likely scream.:eek:

BTW, its forum policy to update every half hour when you get a piece of hardware before everyone else, I hope you realize that.

Hehe ;)

Common clock it clock it higher :D

Yes! Get that thing inside and start clocking him!!:)

What do we think it'll then? I say probs 2.1-2.2Ghz on air.

OH MAN
Been waiting for this!

I woulda taken the day off from work, locked myself in my apartment with a 12 pack, and proceed to EXPERIMENT on that thing!

C'mon bro, hook us up with the results!!! I wanna know!

Wow, great results so far. Push that puppy!!!

Gimme a break guys :D
Testing 2ghz at 1.75V now. Results to follow.
I hope JC comes home soon, I need an AMD kit for my Prommy.

Juplier,
where in Germany did you buy that thing ?
What´s the name of the Computer store ?

No break for you :D
Looking good so far, but I thinks it's safe to say that those cpu's wont' reach 2,3 or more on air like majority of 2400+ and highers, pleas prove me wrong :D

Cooling ? Still using Swiftech 462A with Panaflo L1A ?
Thanks !!

Yep, still with Swifty and Panaflo.

Milka :
Bought the chip in Aachen, http://www.p-c-c.de
I'm going back on thursday or friday, if you want, I can look for others, even at other stores.

2Ghz looking good so far :

Well ???

TB A's are doing 2100mhz. Go for 2200 or 2300 dude!!! : )

This cpu with a prometia might be stable at around 2.3-2.35. Sure you might be able to get a wcpuid screen higher but for being totally stable I say no more than that. Prove me wrong.:p

WHOW!! :D
Really great CPU!

Good to see this out in the wild now.

Eager to see how well they clock as many are hungry for them.

hi! you ppl said something about week 50

i just bought a 1800+ RIUGA week 49... Tbread A, nothing really ODD... but it gets really warm! even on Watercooling!...

tell me how much can you do with 1.70v... and just for fun! i will try to take this "Week 49" to the limit on that voltage too! :D

im with 8k3a+ w/Pc3500 EL....having temps of 45/50º.... i will try to lower them so i can be closer to your conditions!

A vs B battle :D

Yes those tbred A are rather hot especialy if you look at temperature with internal diode.
I had 1700+ for weekend (week 47 realy nothning special)
I overclocked it to 2GHz but I needed 2V and prime95 load temps were 45°C on 8k3a with my new block.
|Oc|REvO_HsArC, at what settings and which waterblock did you get those temps ?

....having 45/50º at 193x10 (1930mhz) 1.62vcore....
with a WAterblock home made by a friend from a local Forum, and some Renault 5 Radiator!!! ( the radiator!!!sucks believe me :D )

i just tryed to put 2ghz, hell, the temps at hardware monitor when POSTing are >50º!!! damn... no Vcore helped me reaching 2ghz stable... I seem to have reached the limit temperature :D BSOD all over the place!

This is good to hear, I mean to know that my block doing very good :D :D

Well, I did a quick try at 2100. Had to increase voltage to 1.85 but Prime crashed and system frooze.
I don't know, maybe the chip needs some more burning in or so.
2 ghz at 1.75V was stable but I fear that 2100Mhz will be about the max with simple aircooling.
Also, using a cheap chieftech 360W PSU. Gonna try with the Antec 400W or CWT 480W. Maybe it helps.
Further testing in the next couple of days. I'll keep you updated.

Jupiler-
I was just curious as to what kind of temps you were getting on this chip. Im excited now, I wonder what this would do in my new Vapochill?

Temps were around 40°C at full load, 1.75V. Don't know if temps on 8k5a2+ are accurate but I doubt they are.

2GHz with 1.75V ain't great at all...... :rolleyes: and that with Tbred B.....

Those might be remarked bad 2400+/2600+ cores..... I don't know.... I was thinking more about 2GHz@1.6V.... not 1.75V... this is weak for TbredB... :(

I think we're expecting to much from these chips. As always, there will be some good chips around and some bad ones.
Only later badges will tell us how good they really are.

I've also been waiting for these for ages. Now I'm a little disappointed :|. Can you tell us your exact cooling setup, please? CPU temp, ambient etc.

Thanks,
dojobi

You're right, but that's TbredB afterall...... it;s supposed to be better than the "A" revision, look all those 2400+ and above.... even the POS 2400+ are doing better..... oh well....... let's do the "wait and see" thing :cool:

Welcome to Xtreme, dojobi.

As posted before, board is the Epox 8k5a2+, cooler is Swiftech 462A with Panaflo L1A, PSU is Chieftech 360W.
Room temp is around 16°C, cpu temp around 40°C at full load.

well.... i suppose you reached some sort of temperature limit.... observe my Xp: 1930mhz and it wouldn't pass!!!... it reachs 48º and bang!! i open my room windows and let cool air enter, i went to 2050mhz just by having cool air around! with only 1.82vcore :D but more than 48º and Bang!... BSOD again...

Thanks for the welcome :)

Sorry I made you repeat yourself. I'd swear I read through the thread for the setup and temps, but I obviously did a pretty poor job.

Anyway, I think you're right, things will improve with these low speed TBredB chips. I'll just wait and see before I buy mine.

Hmm....

8-)

Do these xp1800 t'breds come factory unlocked?

If not do you just do the same procedure as on the 2400?

just for you guys who want more tbred b goodness this thread has some: http://forum.oc-forums.com/vb/showth...0&pagenumber=2

IIRC I saw a week 49 or 48 that was a 2600+, so I think those are the first few weeks of production. I am loving what I see, but as it was with the 1600+'s, I am gonna wait and see what the best stepping is. I got the same board, and a lovely 15C ambient temp waiting, so I am gonna pull the trigger as soon as they start advertising the nice steppings at newegg :D.

All of you may know this already. But i have come to a conclusion that all processor have been tested with it's stock speed at a certain voltage and temp. For example, the 2400+ in order to run it at 2gb at 1.65 and at the temp of 50c. I think the lower ones can also run at 2gb. But it needs more voltage and lower temp.

Let's take a 1800 tbred. In order to run it 2gb we may need 1.75, but we need a low temp in order to get to the speed. If failing to get the lower temp, we may need to up the voltage. Sometime giving higer voltage may not help eaither if the temp is on the high side.

So is not suprising if Jupiler not getting a high o/c result. Overclocking also need some luck. I guess all of you do agree with me on this point. Thank you for reading. This is just my 2 cents. Hopefully you understand what i am tryin to say. hehe.

My 1800+ Aiuga 0247 Tbred A did 2ghz with only 1.575v on my prometeia..
Or that chip sucks..or the stepping that you have isn't the best..
I were thinking like.. 2ghz @ stock voltage...minimum

One thing to note tho, this is JIUCB stepping, which means not only its propably a 2400+ that didn't make it its not even an ex-AIUGB or anything, propably just ex-AIUCB, we all know that the first batch of chips AMD produces are never THAT good and we should wait, I believe that if/when we get a hold of JIUGB or JIUHB and later weeks we'll see much higher speeds

yeh these initial oc results are no better the tbred a's they are to be replacing soon... they are def not underclocked 2400+. but then again the 1600+ was not a underclocked 2100+ until the last few months of the palomino (remember AGOIA was the steppin made for 2100+ and AROIA was the steppin made for 2200+)...

There's a thread in the overclocking w/ a guy w/ 1700+ Tbred B's btw :)

Yeah, we have xp1700 with t-bred b in finland too. I still think it's too early to draw conclusions on how well these will do. There are also t-bred a's that won't really go above 1.9ghz without pumping loads of voltage. Personally I think I'll finally get the watercooling I've been planning, and get a processor in a month or two.

No good news, not good at all actually. :(
Looks like the cpu has hit its limits.
It runs Prime and Folding fine at 2ghz, 1.75V but it doesn't seem to go any higher.
2050Mhz, 1.85V : Prime95 crashes and BSOD
2100Mhz, 1.95V : same thing.
This sucks badly.

Reminds me a little bit like the P4 C1 steppings. They go pretty high on default voltage but then it's over. Even increasing the voltage doesn't provide a better overclock.

As said, newer weeks and steppings might oc much better than this one.

This sound very much like newer tbred A's. So I guess we'll have to wait a little more

jupiler.... read my previous Post!...same happened to me, i just lowered the temps and he started to OC again with lower voltage!! he hit 1930mhz 1.65v at 50º, increasing voltage didn't help... but after cool air got into my room, i went to 2050mhz 1.82v 47º, at 48º it HAngs up! :)

I',m still intrested to hear how it does with water.

not bad for a bad stepping Tbred - B

Im sure there are better stepping Tbred A's out right now...

I mean my palamono 1600+ @ 1836 MHZ was still faster than many Tbred CPUs when they FIRST came out. I think Tbred B needs more time :) Still its keeping up with the more matured 1800+ Tbred A's or at least from his post...
