1700+ Tbred B

**chr!s** · 01-26-2003, 04:39 AM

hi guys

can you tell me something about this CPU....

I bought it yesterday and I hope its a good Stepping for overclocking...

AXDA1700DUT3C
JIUCB 0251SPMW

sorry for this short thread and bad english, I come from germany

thx for your replys

**DeBastaard** · 01-26-2003, 05:07 AM

hmm well it's a week 51, so i recon it would do something like 2.2ghz on air with the right components etc...

**jarthel** · 01-26-2003, 05:08 AM

That's a good one! Congrats.

**mongoled** · 01-26-2003, 05:25 AM

Ive got a friend right now at a fair with 3 chips exactly like the one above in front of him
i need to make a decision NOW

So what do u guys think should i get one????

Quick responses if possible!!

**chr!s** · 01-26-2003, 05:28 AM

my experience with this cpu isn't very good...

I have tried to OC this CPU on a 8RDA+ and an Alpha Pal 8045, but I doesn't get over 1.9ghz with this CPU

I can't understand that

**mongoled** · 01-26-2003, 05:32 AM

Sorry to hear that

What voltages are u giving the processor?

**chr!s** · 01-26-2003, 05:39 AM

max. 1,9V ... but it isn't stable on 2ghz

**mongoled** · 01-26-2003, 05:40 AM

Ok i decided to give it a miss.

Hope i dont regret it.

Wish there were JIUHB or JIUGB chips there, but no such luck.

Lets c when the 0301 chips start showing up hopefully soon.

:p

**chr!s** · 01-26-2003, 05:43 AM

I dont' understand your english... can you write sentences, which are easier for me??

thx for your help

what would you say with your post #4 ??

**mongoled** · 01-26-2003, 06:13 AM

lol

Ok this is what i mean

I will wait for the cpu stepping to change to

AIU.......0301 etc.

Hope you understand.

the "J" stepping 1700+ TBred B i got is week 51, and currently i have run at 1964mhz at 1.7v on MSI KT3 Ultra2 (11x178)

very stable, but too bad the max vcore on this board is only 1.7

**chr!s** · 01-26-2003, 07:51 AM

@ mongoled... ok, I think I understand what you say...

where do you get these informations about good steppings and series ??

**DeBastaard** · 01-26-2003, 08:01 AM

Maybe you should try some other memory, or increase your memory voltage and lower your timings ?

**chr!s** · 01-26-2003, 08:17 AM

I have used FSBs from 166-190 with CL 2,5 3-3-7 @ 2,77V but the CPU doesnt go stable over 1.9ghz

now i running my 2000+ palomino @ 10.5x166 with CL2 2-2-5 ... rock - stable

My Tbred B is a bad one and I can change it by the shop, which sold me the CPU

Can you give me some good Steppings and series for 1700+, 1800+ and 2400+ ??

**chr!s** · 01-26-2003, 09:22 AM

nowbody who knows some good steppings??

I take a look in the "Tbred B OC information thread"... but there are many 2400+ and I'm searching for 1700+ oder 1800+, primary

**GVCryan** · 01-26-2003, 09:44 AM

Jiuhb's are running pretty good, but you can only find them in Slovenia or South America.

**jmke** · 01-26-2003, 04:05 PM

JIUCB XP1700+ here @ 2260 with 2v vcore

your jiucb seems to be the exception rather than the rule.

chr!s, the best 1700+ and 2100+ steppings seem to be jiuhb with week 0252 best for 1700+ and week 0248 being best for 2100+. Avoid jiucb steppings and avoid week 0301 even for jiuhb.

Sorry, but I haven't seen much about 1800+ t-bred B's.

**twiggy** · 01-26-2003, 09:16 PM

Me and my bro have 6 JIUCB week 51's and all of them will do 2.2ghz at ~1.9v on air. We have 1 JIUCB week 50 that does 2.2ghz at 2v on air.

Interesting, perhaps the week matters more than the stepping. I would still look for an early 0250 or earlier jiuhb if possible, though.

What sort of cooling are you and your bro using twiggy?

**twiggy** · 01-26-2003, 09:29 PM

Im using this but mine is copper but with the same fan. My bro is using a slk 800 and a 92mm tornado at 2800 rpm's.

Most of them topped out ~2.4ghz but a couple did 2.5-2.6ghz, stable too. 24/7 folders.

I agree tho if you can find a JIUHB then grab that for sure.

**chr!s** · 01-27-2003, 06:39 AM

hmm.... I can't believe that... my processor doesn't reach these high frequencies

perhaps I make something wrong, but I used voltages between 1.6V - 1.9V and the temperatur was with 50°C 'cool' for my air-cooling

normally the 8rda+ is a good board for overclockers and my RAM is rock stable @ 180mhz and CL2

It seems to be a very bad CPU I've bought

Now, I use a 2000+ palomino with AGOIA Y stepping... can you give some advices to OC this CPU... which voltages are "healthy" for this CPU... ??

@twiggy... can you say me the settings of your JIUCB @ 2.2ghz (multiplier and FSB)

**twiggy** · 01-27-2003, 08:28 AM

At 2.2ghz I have it at 133x16.5.

**chr!s** · 01-27-2003, 10:26 AM

how can I apply these high multipliers...??

I can increase the multi only to 12,5... all higher multis aren't accepted by the system... all lower multis are accepted...

I have closed all L1 bridges on the palomino....

Probably I have the chance to get a 1700+ JIUGB... is it much better?... I don't know the week... is it more important than the stepping?

**m0rm0r** · 01-27-2003, 10:48 AM

i have jiucb 1700+ 0251 too. 2300mhz @2v with watercooling,
2150mhz on air (old coolermaster aluminium) and 1.85v
