hey all, just replaced my old DUT3C JIUHB 0307 that did 2.1 ghz max. with a "DLT3C" "AIRGA" 0236. i know it will do better because its a "DLT3C" but how much better ? never heard of a "AIRGA" ???

[brennan77]

NOOOOO!!!! Tell me your joking! I'm sorry to tell you this, but that's an "A" core. You can tell by the AIRG"A". It's just not gonna overclock well. It'll be a lot worse than what you had.

[brennan77]

That's an old one too. So it won't do well at all.

[felinusz]

I am very sorry to tell you this.

You have gotten a Thoroughbred "A" processor -

AIRGA which, although it stocks out at a 1.5 Vcore, isn't exactly a superb overclocker. The Thoroughbred "B" processors (the only 1700+ example being the infamous JIUHB) are the ones that everyone raves about...

This chip might actually perform roughly on par with your old one - if slightly better. I would eBay it, and try for a Thoroughbred "B" 1800+ from newegg.

[MameXP]

oh man, :'( I'm sorry.....hic hic

[Burnt_Ram]

yup it sux !!!!!!!!!!!! i totaly forgot about the "B" part.. i got stuck on the D"L"T3C over my D"U"T3C arrghhhh freakin "A" stepping ! WTF was i thinking. you would think i was a rookie or something anyone want to buy it LOL

[felinusz]

Seriously - you can sell it on eBay for a little less than it cost you. Most people buying thee don't plan on overclocking them, and will jump on a good deal.

Good luck selling it!

[Burnt_Ram]

i bought it locally. so i'll hopefully be able to trade it for some cash and a "GOOD" 2500 barton ! any suggestios on 2500 steppings ?

[CrashOv3r1De]

that some bad luck there bro. id step on it if i were you =D

[Burnt_Ram]

ya, i almost did. it was my own stupidity that i bought the piece of sh!$ in the first place ! ive been running this1700+ so long i forgot the basics of CPU selection they'll take it back. well atleast they better then i think i'll try a 2500 barton ? i just want a cpu that will do 2.5 and atleast 200 fsb

The chance/probability of overclocking on air a Tbred B 1700+/1800+ to 2.5 GHz or a Barton 2500+ to 2.4 GHz, based on the poll statisitic taking into account of chip, cooling, skill, randomness, ..., is about 11.9%.

As for FSB 200 MHz, that depends mainly on the motherboard and memory.

From your sig, you have a A7N8X rev 1.04, for that revision, most board may not be able to do 200 MHz without a Vdd chipset Vdd mod. Chipset mod would be able to bring it to around 210 MHz.

Rev 2.0 nforce2 (aka Ultra 400) officially supports 200 MHz. Specifically, the ABIT NF7-S rev 2.0, from what I've seen, have a good chance to average around 220 MHz with good memory modules using Winbond CH5/BH5 chips.

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.


Usually, on the average, the Barton does about 100 MHz less (older Barton's are 100-150 MHz less), compared to the DLT3C 1700/1800, so I would extend the distribution for Barton to:

The distribution centers within the interval 2200- 2300 MHz.
...
Probability for 2001 – 2100 MHz = 11.36%
Probability for 2101 – 2200 MHz = 14.68%
Probability for 2201 – 2300 MHz = 19.94%
Probability for 2301 – 2400 MHz = 18.28%
Probability above 2401 MHz = 11.91 %.

Approximately, it means the Barton max overclocking frequency center around 2250 MHz, with a sigma of 125 MHz. Assuming 84.1% of the chips are below 2375 MHz.

thats the weird part about my rev 1.04 . about a month ago i thought i fried it, and bought a rev 2.0 now the really weird part is it wouldnt do any better FSB than the 1.04 ? the "ram" ! its freakin pc "3200" shouldnt it do atleast 200 ? i wish i knew someone that had some corsair or ocz or some highend sticks. then maybe i could comfirm thats its the ram, but ive seen other guys getting over 200 fsb with generic ! dunno

[murrayman]

Any PC3200 won't do the job. I've learned that the best ram would be generic Elixir. Second place, Kingston. Third, Geil. Not trying to hurt your feelings or be mean, but that Samsung RAM you have...IT'S SUX! They are the worst in the memory line! Not suprising that Samsung would go out and make it more expensive than everything else even if their terrible. You SHOULD go out and spend about 60 bucks on generic Elixir memory. Yet have I to see a better brand of memory for OCing. What's good is that their the very cheapest .

[Burnt_Ram]

Elixir huh ... maybe i'll see if its available to me

[hitechjb1]

From the sig, if you mean Samsung 3200 memory, it depends. There are some Samsung labelled as 3200 (by vendors) which are overclocked 2700 memory. With high voltage and relaxed timing, they may be able to do 200 MHz and not much. Some 2700 may not be able to do 200 MHz at all.

If you want to get good one for 200+ MHz, get these
- TwinMOS 3200 w/ WinBond chips (CH5)
- HyperX 3000/3200 w/ WinBond BH5 (you need to check the right version for them)
- HyperX 3500 w/ WinBond CH5 (rated 217 MHz)
- Buffalo 3700 w/ WinBond BH5 (rated 231 MHz)

All nforce2 rev 2.0 motherboards w/ PC3200 memory, if not defective, should do 200 MHz.

Among nforce2 motherboards, if aiming for 200+ FSB, the NF7-S rev 2.0 has the highest probability to get there, average 220 MHz +- 10 MHz.

sorry dude!!! hope things work out for ya

I have that same chip, not the same stepping, but did ok for a Tbred A:

With the setup i have now, i'd prolly get it up to 2.0:


I would keep it as an emergency chip or use it for a second rig like what im gonna do:

Combo that baby with some pc3200 and you've got yourself a nice media center:

btw my Tbred B 2100 is running @ 2.4 wit a load temp of 48 celcius

i got almost 2 gig out of it, but thats not what i was after... stupid me. i need to go back to cpu pickin' school lol

go to www.cpudatabase.com its a good site that tells u wat other ppl have, wat steppings, vcores, etc...good place to check for "good" steppings

btw, i forgot how to make it so when u quote someone, it also shows their sn, how do u quote someones sn?

I had the exact same stepping for a bit, I have a crappy PSU that blew out while i was trying it out but it was best at around 1800mhz, would do 1900 on a better PSU i think but it really isnt going to be worth the hassle. Like the others said sell it on ebay as brand new used for a week or something then buy a newer 1700 or 1800 B from somewhere that doesnt overcharge for good steppings and see if u can find a good one. Thats my take on it anyway.
By the way is anyone else insulted that they charge for the stepping now? Its like AMD sells them a big box of chips at one price, they take out the B core DLT3Cs (probably all the 1800s they get now) then double the price and make a killing. I think thats just rude, the reason u buy an 1800 that does 2600 is because you pay less, if you wanted a 2700 u could get one for the price they sell the 'magic' 1800s at.
