Athlon 1800+ DLT3C JIXIB any good

[Gun4u]

Hi I just got a athlon 1800+ DLT3C, JIXIB 0338 Is it any good?

Thanks
Gun

Yes, its excellent. Now tell us where you're getting it from! :D

[clockedOut]

I hope the multi isnt locked...week 38 is getting pretty close to the magic #39. Either way at week 38 it should scream.

My friends 1800+ died and he upgraded. He said I could have the replacement if I shipped it to AMD. I shipped it and got this one 1800+ DLT3C, JIXIB 0338.

From my own experience on three Tbred B 1700+/1800+ DLT3C,
- JIUHB 0310 XPMW 2.54 GHz @ 1.92 V, max at 2.6 GHz @ 1.98 V
- JIUHB 0310 WPMW 2.56 GHz @ 1.95 V
- JIXIB 0332 MPMW 2.56 GHz @ 1.90 V
all under 50 C on air w/ Prime95 using SLK-800U/947U w/ TT SFII.

What is the probability of achieving certain level of overclocking

Components and the composite system follow normal distribution. Each component centers around a mean and has certain standard deviation (or sigma). In normal distribution, 84.1% of the population is below +1 sigma, 97.7% is below +2 sigma, 99.9% is below +3 sigma, about 90% is below +1.3 sigma.

E.g. looking at the poll about the Tbred B 1700+ DLT3C in this forum, even there are many unknowns (or randomness, including voltage, cooling, skill, degree of overclocking, margin of errors, ...) about how each number is obtained, but the 360+ data points shows something. As of today (10/18/2003), the distribution centers within the interval 2300- 2400 MHz.
...
Probability for 2101 – 2200 MHz = 11.36%
Probability for 2201 – 2300 MHz = 14.68%
Probability for 2301 – 2400 MHz = 19.94%
Probability for 2401 – 2500 MHz = 18.28%
Probability above 2501 MHz = 11.91 %.

Approximately, it shows the 1700+ DLT3C max overclocking frequency center around 2350 MHz, with a sigma of 125 MHz. Assuming 84.1% of the chips are below 2475 MHz.

For the new Tbred B 1800+ DLT3C (week >= 0332), such as NIUHB, JIXIB, JIUIB, ..., from my impression from reading the posts, there is a chance some may average 50 MHz more than the 1700+ for the same voltage. I would say it is a tie between the new (>= 0332) 1800+ DLT3C and the 0310 1700+ DLT3C XPMW.

There is no standout 1800+ stepping as there is not much data points as the more established JIUHB 0310 XPMW/WPMW. I would say
- 1700+ 0310 JIUHB XPMW being more conservative and "proven"
- 1800+ DLT3C (newer date >= 0332) JIXIB, JIUIB, NIUHB seem to be good, if 1700+ not available.

So I would say Tbred B 1700+/1800+ DLT3C is good if you can find them. Especially it is around $50-60, and delivers about the same performance as a Barton (usually overclocks 100 MHz less and chance of getting locked multiplier).

Gun4u, clockedOut WELCOME both you guys to the forums.

[clockedOut]

Thanx iceman!!

Well, AMD shipped you that processor?

That is two week 38 Thoroughbred sightings now, and if AMD shipped you one than it is almost certain that that week date is the most recent batch that AMD has in stock, thus making it the last batch of Thoroughbred processors ever to be made.

Congrats Gun4u - you have one of the "Last of the Thoroughbreds".

Tell us how it overclocks.

Now I wonder if AMD would be willing to sell these to individuals @ retail price? If They have discontinued their Thoroughbred line, then I would imagine that they want to get rid of them.

My JIXIB 0332 does 2520 Mhz (and hopping ever upwards!! :)) on a 1.85 Vcore.

Yea I got it straight from AMD after I sent them a fried retail 1800+. They shipped it to me in 3 days which wasnt bad at all. I got a question, what type of fan should I use on it. I have just tested this cpu at normal speeds and its not locked, which is good. But I not going to go for higher mhz without the right fan.

Thanks

The best HSF for your Tbred B 1800+ DLT3C would be a SLK-947U with a ThermalTake Smart Fan II. The fan is adjustable in speed which can give you option of max air flow at 4800 rpm for testing, or lower noise at 3500 rpm +- for daily usage.

I use the SLK- HS and TT SFII to overclock all my Tbred B (see previous post).

I don't know if SVC still has the slk 900A for 19.99, but that's an excellent heatsink. Couple that with a decent fan and you will have plenty of headroom for your overclocking.

[StinkBreff]

I think they ended the slk-900a deal at svc.com ..

[mata2974]

that is a good chip!!!!!!!!!!!!!!

[StinkBreff]

It just crashed prime 95 after 2 hours - upping volts to . 1.7

[stamasd]

For some reason I had the impresion that steppings starting with J weren't so great. Am I wrong?

[StinkBreff]

I htink there were some Aiuhb 1800's , but the ones everyone has success with are Jiuhb , Jixhb , and Jixib ( in that order ) .. Also stepping Niuhb ( blue core or Red core ) do VERY well ..
There was also a Jiucb core which was not good at all ..

[felinusz]

Did you say blue colored core? Do you happan to have a picture - I have never seen a blue one before, only red and silver, and I am curious :p.

[StinkBreff]

Yeah bluish .. I dont have a pic ..
Edit found a pic ..
Email it to ya ?

[fldrice]

Ususally the redish cores overclock very well, the purple ones are average, but I've never seen a blue one.

[StinkBreff]

I am going to attach an image .. It doesnt look blue , but it is .. BTW that is a 2400 , supposedly 2400+ and 1800+ were 99% of the blue cores , a few in the 1% 1700+'s ..
