Thoroughbred 1700+ Overclockage

[RedShirt]

Hello all.

First, let me say that I KNOW you are never guaranteed anything when overclocking is concerned? but this is a very strange situation.

A friend and I both purchased 1700+ Thoroughbreds from newegg and they both will not overclock much at all.

Both of these processors are the revision B core. I have tried my processor on two separate motherboards, a KT400 and a Nforce2, both boards have execelent overclocking options. In my KT400, I currently run a 1600+ at 1750 mhz at default voltage.

When running the 1700+, the both boards will not even post. The computer will post at about 150 MHz bus, but is no where near stable, regardless of voltage.

My friend is in a similar situation. I find it odd that both chips perform like this.

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!

Anyways, if anyone else had not successfully overclocked at 1700+, could you please post a reply? Thanks.

Edit: By not being sucessful, I mean not being able to run the chip at 166 FSB at an 11x multiplier.

No problems here. Running my 1700XP Rev B at a "mild" 11x166, 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.

What memory are you using in the sys'?

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 10.5x166, so I know the board can handle it.

In fact, I have unlocked the processor and it runs fine at 11x166 with a voltage bump. At 10.5x166 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.

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.

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 11x166.

I am wondering if ANYONE has not gotton a Thoroughbred 1700+ to overclock to or beyond 1.83 GHz.

 

[human2k]

there have been plenty of people who have gone over 2GHZ. just ask that one dood who fried his.

Why do I get the impression that you are thread crapping?

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.

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

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(11x185). Both on leadtek nf2 w/ samsung pc2700.
Maybe you want to try to set ur ram less aggressive?

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?

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?

2Ghz (2400xp) w/ 12X166 @ 1.65V MSI KT4 Ultra Samsung PC2100 RAM.

 

[microAmp]

Are you using aggressive memory timings? Like CAS 2.0, etc...???

 

[mr_cheesy]

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.

 

[Blooz1]

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.

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+ 10x190MHz @1.775v here on an Epox 8RDA.

 

[howdyduty]

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 10x166 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 10x166 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 15x166 with air cooling. That may spur another upgrade.

i've bought two 2100+'s from them with no problems.. a 0302 and 0304

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...

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...

 

[GagHalfrunt]

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.

 

[Killrose]

howdyduty, 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 @10x190MHz 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 60x15mm fan crap.

More system specs please
