Thoroughbred 1700 + Overclockage [newegg] [b core]
Q: Hi all.
First, let me say that I know you never when overclocking is guaranteed? but this is a very strange situation.
A friend and I both 1700 + Thoroughbreds bought from newegg and they both will not look all.
Both overclocking these processors are the revision B core. Ive tried my processor on two different motherboards, nForce2, and a KT400, both boards execelent overclocking options. In my KT400, now I have a 1600 + running at 1750 mhz on standard voltage.
When running the 1700 +, both boards will not post. The computer will be at approximately 150 MHz bus, but no where near stable regardless voltage.
My friend in a similar situation. I find it strange that the two chips to implement such this.
However, I understand that overclocking is not a guaranteed thing. I thought I wonder if others have this problem because I read all the time about people getting the 1700 +? S to 2.2 GHz!
Anyways, if somebody else had not successfully overclocked to 1700 +, you can post a reply? Thanks.
Edit: by sucessful not, I mean not able to run the chip at 166 FSB with a 11x multiplier.
Re:I have a 0302 and it seems like a super overclocker, but i just don't have a good mobo for it.
Re:guy, What kind of ram do you have? And are you using the latest Epox bios for your motherboard? Maybe some of your stability problems are from running your ram out of spec. Maybe instead of upping your CPU core voltage you need to bump your ram voltage from 2.5 (std) to 2.7volts?
And I think you need to find out if the Epox reads from the CPU on die or from a thermister under the CPU socket. If its from the CPU die, yes, I would add 10-12C to what others are getting reading the temps from the CPU Socket A thermister located under the CPU.
My temp @10×190MHz and 1.79volts reads 46C. This is measured by a thermister under the CPU. Your 60C temp, if being read from the CPU die and not the socket, is well within reason. Also, are you using a good cooler? You should have one with at least a copper plug if not pure copper for overclocking T-breds. none of this whimpy aluminum 3500RPM 60×15mm fan crap.
More system specs please 
Re:I'm just wondering what week and stepping you got as it does not seem to have been mentioned. It's pretty well documented that all the late 2002 chips and the first couple of weeks of 2003 have been excellent overclockers, especially the 0302 'B's. But not much has been said about the newer weeks and steppings. Is your chip one of a newer batch? Maybe something changed and they don't OC as well as some of the previous chips. OC ability is luck of the draw, but it seems highly unlikely that both you and a friend both got unlucky at the same time when buying from the same company.
Re:my 1700+ A is hitting 12.5 x 143, I'm haven't seen any definitive info, but it looks as if the A's are FSB limited correct?
Not true at all… I'm running a 1700+ tbred A using kt333 chipset… have it at multiplier 8, with fsb of 190mhz. I have corsair xms3200 c2 ram , which I think is the main factor in determining fsb limitations… I can't go any higher due to locked agp/pci ratio…

Why do I get the impression that you are thread crapping?
i don't think he's crapping your thread… there is a common poster on AT forum that has fried 2 of his 1700+'s already…

i've bought two 2100+'s from them with no problems.. a 0302 and 0304
Re:I have 1700A and 1700B, both from Newegg, with similar issues. 1700A ran hot at defaut and to hot over 1.467ghz. 1700A did not OC well. The 1700B runs well at 10×166 vcore-1.575 but gets to warm and instable above that no matter the vcore up to 1.8v. The Epox 8K3A likely reports the cpu core temp 8-12C higher than others. Odd thing is the 1700B is a stable OC'er but the core temp reads higher. Even at default clocks the 1700B reads higher (around 52C). At 10×166 runs around 60C. The 1700A ran default clock around 50C. The 1700B temps were a shocker at first but it runs well reaching the covetted 166 fsb. The 1700B OC'd some while running at 166fsb. That was the goal since the 1700A wouldnt budge on the same setup.
Wondering if a future stepping 2400+ will pull 15×166 with air cooling. That may spur another upgrade.
Re:There are a lot of motherboards that don't support T-breds, or need a bios up-date to do so. If you can't even boot up with these, then you need to check for bios upgrades for your motherboards.
T-bred/B 1700+ 10×190MHz @1.775v here on an Epox 8RDA.

Re:I've had better luck using relaxed timings (2.5-3-3-6) on my Kingston PC2700 with my 1700 "B". My board is an Epox 8K5A2, and I'm running at 2083MHz.
I have both a T-Bred "A" and a "B", and my "A" wouldn't run reliably over 2GHz. It would run Prime95 for 24+ hours at 1.92, however.
Re:my 1700+ A is hitting 12.5 x 143, I'm haven't seen any definitive info, but it looks as if the A's are FSB limited correct?
I'm running crucial pc2700 and actually underclocking. I'd love to get to 166 FSB, but it really doesn't seem to like it.
Re:Are you using aggressive memory timings? Like CAS 2.0, etc…???

Re:man you tbred 1700+ b owners are making me jealous. i've got a locked 2000+ palomino and i'm thinking of selling it off for one of those. should i?

No problems here. Running my 1700XP Rev B at a "mild" 11×166, 1826mhz with my 8k3a KT333 (default voltages too). It could easily go further, but I'm holding off until I can upgrade the R8500 I'm using right now. I used the wire trick to unlock the lower multipliers.
I was under the impression that Tbred "B" chips are mult. unlocked by default. If the chip is slower than a 2100+ the mults. 12.5 and below are unlocked. If the chip is a 2100+ or faster then the mults. 13 and above are unlocked by default. Or is this only for NForce2/KT400 boards only?
Re:I have both 1700+ tb'a and tb'b. For the tb'a, I hit wall at 1.73ghz. For the tb'b, I am at 2.04ghz(11×185). Both on leadtek nf2 w/ samsung pc2700.
Maybe you want to try to set ur ram less aggressive?
Re:I have 2 that are doing 1775 Mhz (12.5 X 142) @ 1.7V only because they run on a mb with limited O/C capabilities (KT133A running PC133 memory).
It is multiplier locked beyond 12.5 and I can't lock the AGP/PCI/FSB.
I'm sure mine could go higher if I weren't limited by the mb.
They run loops of 3dmark2001se without breaking a sweat

The QUESTION I have asked from the begining is has anyone NOT NOT NOT NOT NOT gotton about 1.83 Ghz.
However, in your first post you pointed out that I was complaining and that yours hits this speed.
Then in your second post you were trying to be funny stating that running at that speed fries the processor.
You have been zero help to my question. All I want to know is if my friend and I got two of the worst overclocking 1700+'s ever made. I am not whining or complaining that it doesn't hit 1.83. I am just curious if other people have had the same situation as myself because whenever I read anything that has to do with a 1700+ overclocking, I never see anyone stating that they couldn't get a good overclock.
And even in this thread, no one has stated that they couldn't get their proc to 1.83, which in turn makes me think ours are from a bad batch or something.
Am I going to return the processor? No. I totally understand that I bought a 1700+ and that it is only guarenteed to work at 1700+ speeds.

my cpu hits the wall at 1.86GHZ at 1.7v, you dont see me complaining do u?
I am not complaining. I have tried to explain this by making these statements:
First, let me say that I KNOW you are never guaranteed anything when overclocking is concerned? but this is a very strange situation.
However, I do understand that overclocking is not a guaranteed thing. I just am curious if others have this problem, because I read all the time about people getting the 1700+?s up to 2.2 Ghz!
I am perfectly fine with it not hitting anything above about 1.6 GHz, I am just wondering if anyone else has had this problem with a Thoroughbred 1700+ CPU. And yours does in fact hit the mark of 11×166.
I am wondering if ANYONE has not gotton a Thoroughbred 1700+ to overclock to or beyond 1.83 GHz.
Re:my cpu hits the wall at 1.86GHZ at 1.7v, you dont see me complaining do u?
Re:I've tried with Crucial PC2700, Corsair DDR400 Ram.
My friend has tried also with Crucial PC2700 Ram.
My system NOW runs flawlessly with a 1600+ (.18 micron) at 10.5×166, so I know the board can handle it.
In fact, I have unlocked the processor and it runs fine at 11×166 with a voltage bump. At 10.5×166 it runs at default voltage very very stable (never any errors).
Sooo…. I have determined it is the chip. Perhaps Newegg had a bad batch???
I'm just making sure AMD hasn't done some sort of clock limiting on their chips… Since a lot of people like to buy these 1700+'s and overclock the hell out of them.
