Ok Perk that's true, it seems that those chips 26/2700 with 333fsb are hard for oc. I can do 11x225 synch but with high voltage (2.0v) and high temp about 60c, with a big drop at 3DMark 2003, and i don't like this.
They are other things also that take part of this as vdd (mine is mb max default 1.7v) and NB chipset. For now i am waiting for a new bios from abit and keep trying but always for a very stable system without bios or HD corruptions.

I figured out the confusion with the L3 modification. On 266FSB 2400 CPU's connecting the 5th (or last to right) "pit" on the L3 Bridge, unlock's the full range of mutlipliers, per the link below which was performed on a 2400+; http://www.overclockers.com.au/article.php?id=118669 Albeit a 2400, it's a 266FSB, so this mod (I beleive) only apply's to CPU's up to 2400, and with 266FSB (DDR). Someone please correct me if I'nm mistaken. I looked for about two hours, and was unable to find any (Bridge) mod which unlocked the entire range of multiplers not just below 12.5x.

man i did the mod with the fifth bridge cut on the L3 and it unlocked all the multipliers?? whats the diff with the mod you just found? man too many mods kinda confusing? you think this mod will work on the xp1700's as well just incase i run into the same problem when i get my new xp1700? well for now i just want to figure out this volt mod for my epox that is my next mod to do... that i neeed to read up on the links i got vefore where dead :0(..

later perc.

It seems like cpu can hold higher fsb but not easy at list mine, and higher MHZ. After vdd mod about 2.1v and new bios from ABIT gone to 225FSB and keep trying.

Aristidis:

yes dude i think your right the newer xp24/2600's do seem to not like the higer ocs at all seems my xp17/18oo "B" chips can run 400fsb alot nicer than my xp2600.. my xp2600 at 400fsb has alot of screen flicker it wierd cant really explain what it looks like you probly have to see it to know what i mean but not only do i get this screen flicker it just seemd unstble like anytime the thing could crash .. now with either one of my other two chips they dont act like the 2600 does infact the 1800 was my first chip i tryed for ocing and that sucker at 400 fsb just seems rock solid and no screen flicker at all i mean at first when i seen this screen flicker i thought it had to do with the video card and the fsb causeing the agp frequency to be a little on the high side but this is not the case at all i think its just that the xp2600 seires chips dont do well with anything above the rated 333 fsb atleast in my experiances? doesnt really make sense either cause IF in fact these xp1700s and 1800s are relabeled chips then they were bult with tthe 333 fsb and all that making them the same chip as the 333 xp2600 and up chips so im at a loss for words on this topic right now? i do know one thing and thats that these 1700s and 1800s sure do make a great cpu im running the xp2600 speeds on this xp1700 right now with 1.5v rock soild stable and it well do 23/2400 mhz 400 fsb all day long.. 2300 being the most stable oc i can get right now but still this aint to bad for a 60 dollar chip i say.. oh well sorry for the long post i may have gotten off topic a tad so please forgive me...

later guys.. perc.

Hi Perk
Just returned from Holidays. Yes i think that you are right.
I bought a new 1800 B chip and the results until now are impressive, but i' going to open a new topic for this.

Nice overclock! 11x222! How do you like the new SLK900? I have the SLK800, but I heard the SLK900 uses a 92mm fan, is this true? That's one of the highest 1800 overclock's I've seen.

You can use an 92mm fun but if you can find a high-speed one. For the moment i use Thermaltakes smart fun II 4800rpm and 68cfm and the temperatures are min 38c and max 45c.
I thing that this chip is a good one and i fine over-clocker for only 70euro.

What's the stepping, and code of that overclocking demon? If you have it written down (which most people forget to do) the four letter code after the date, for example JIUGB0310XPMW (this would be the third line of code). If you have it I'd appreciate it.

The code is JIUGB0309MPMW but i think that more important is the date (maybe older is better). Mine is 0309 and they say that this stepping is one of the best.

What do you think about JIUHB 1700DUT3C 0307? I haven't seen any as yet, but I keep reading people with JIUHB 1700DLT3C 0310 XPMW/WPMW are only hitting 2200MHz.

Maybe it's better. i cant tell you exactly but after all i think that sometimes is matter of luck to find a good chip.
But you can see also some digits of the serial number. For example: xxxxxxx28xxxx. 28 means it is a downgraded version from 2800+ Thoroughbread etc. the best are 25,27,28. And for the last 4 digits that they mean the batch production serial number of the CPU, in one batch of numbers with 0001-0300 will relatively have very high chance to be overclocked at higher speeds. Thats all i know and i hope that they can help you.

I've posted several topics about the program I believe your referring to http://mp3.zonebg.com/cpu/cpu.php from Bloodys.com, and many refute it's validity (including one of the authors recently). I see it's still used though, and in fact GajmeVE has begun using it in their AMD CPU sales description pages.

I've been requesting, and compiling data relevant to this, which is one reason why I asked if you wouldn't mind including the entire CPU code. Here's an article much more indepth then the program which purports the 8th, and 9th places in the 2nd line of code pertain to the original CPU PR; http://lowyat.isentral.com/guides/athlonxp/  I beleive AMD hasn't produced ANY core's specific to lower speed TBred's. I'm sure some will offer a retort to that statement, however; consider the following. By my estimation, 99.9% of TBred-B's AXDA1700's either DUT3C or DLT3C are attaining minumum 2800 PR speeds. In fact their performance is indicative of XP3000 speeds, and the industry standard performance ceiling which every processor is capable of. Meaning these processors are reaching 2200MHz to 2300MHz at default Vcore! And 2.4GHz to 2.7GHz extreme overclock's. Just visit, Xtremesys, or any Hardware forums where these topics are frequently discussed, and you'll see my theory is emprically verified.

We know it's common industry practice when producing processor core's to maintain consistency where feasable. Especially when wafer yeilds are producing such high quality cores. The entire "art" (hobby) of Overclocking is founded on this premise. And the apotheosis for Overclockers, are circumstances where it's less costly (for whatever reasons) for a manufacturer to "relable" or "underclock" their inventory, then it is to start-up additional production lines. Current Lithographic equipment necessary for the chemical (resist) etching of processor cores, can weigh as much as 20 tons, and cost upwards of $15 million. It's estimated the total cost of setting up a production facility for the micro-processor fabrication costs approximately $2.5 billion! ( www.cpuplanet.com/features/article.php/2105531&nbsp Ergo it's more cost effective to simply relable/underclock processors (especially since AMD over-estimated the popularity of their 333FSB TBred line) then to set up additional production facilities.

I think that you are right about all this but after all i believe that sometimes it's luck for a good chip, and a good burn in. I have noticed that after running 24 hours of folding i can run the same speeds on my CPU lowering voltage 0.1V.
And a question: I have RMA my old XP2700+ and they gave me a new one box with stepping AXDA2700DKV3D 4140463250016 AJIUB0245MPM. Do you have any idea if this chip is a good overclocker because my old one was a disaster.

Unfortunately i haven't found anything about AJIUB yet, now if it were AIUGB, those are hitting 2600Mhz. But I'll definately keep looking for you.

Sorry again.....

On AIUHB somone attained 2380MHz @ 1.85Vcore, on a SN41G (FN41 ?) anyway that's the only AIUHB so far, and I'll keep looking. I'm sure I'll find some more.

What I would do is contact the dealer who replaced the chip, and ask them what steppings they have. If they value your business, and especially if you spent large sums of money there, it's not an unreasonable request for such a costly processor. You never know till you ask. Steppings to look for are AIUCB, AIUGB, and ACRGE (however I cannot confirm the validity of the last code.)

I have already return this chip and i get a 2100+ and some other thinks of caurse.
First running 11.5x210 with 1.8v stable. Now just burning to sea what i can get, but slowly because in my country temp's are 35 to 37c.
In some more days i thing that i can get some resaults.

Aristidis, I noticed in your sig you have the SLK900. Did you own the SLK800, before getting the SLK900? And if so, what's the difference in performance between the two.
