1700+ T-bred-B 1.5v O/C but hit a wall?

[SparkyJJO]

Here is what I got

AthlonXP 1700+ Tbred-B 1.5v
nForce2 Ultra-400 chipset
Thermaltake Volcano 11+ solid copper heatsink

Right now I got it at 171 x 10 at default voltage (default is 133 x 11) and it runs perfectly stable and about 95 degrees F (I think that is 45 degrees C) so cooling isn't a problem. But as soon as I step it up even a little it won't boot. I tried increasing the voltage a little to 1.65v and still nothing, and I am not comfortable about overvolting too much. any ideas? I heard that some people have gotten a similar proc to almost 2 GHz.

 

[hytek369]

average overclocks have been 2.2-2.3ghz at around 1.85volts

btw, 100 degrees F is 37 degrees C

 

[fleflikr]

more voltage.........try 1.7 or 1.75

 

[fusionpit]

My DLT3C Is running at 11.5x200@1.65 right now, and earlier 13.5x166@1.625V

OK, so 35 degrees C then (I knew 45 sounded a little too high )

More voltage? OK, I'll try that, I just don't want to go too high.

Perhaps its your ram? Do you have PC3200 ram or better?

 

[jjyiz28]

write down the entire stepping code. just to make sure

 

[pillage2001]

Might be your RAM pulling you back. As the other's said, full stepping please.

 

[jjyiz28]

pillage what volts are u running with that chip in sig?? curious, cuz i have same chip, DUT, but don't have right board for oc

 

[myocardia]

I bet it's your ram holding you back. See if you can borrow some PC3200, PC3500, or PC3700 from a friend for an hour or two.

1.7v to run at that speed. Could have gotten 2.4ghz and above but I don't like the heat dissipated. I believe mine was a week 19, 03

 

[bootoo]

Yup, up the vcore. Back it off a little, benchmark it, and then up the vcore and up it up a bit on the fsb. You can do more I think.

You've got good temps, don't worry too much.

y don't he just run it async to make sure? eh/?

 

[SparkyJJO]

Right, I have the RAM locked down to its default 333MHz speed, the ram is Geil PC2700. I'm not able to get the stepping quite yet (I'm not at home) but I'll get that on here soon. I'm currently running it overclocked at 1.5v (the default). I did go up to 180x10 at 1.65v and still got a system hang. I'll try 1.7v next.
I'll get the stepping here soon.

BTW, even if you don't have an nForce2 chipset you can still get higher than default. 145x11 gives you 1.595 GHz and is still within PCI and AGP limits. I was able to get 155x11 (1.705 GHz) and even though it was outside the recommended PCI and AGP it was still stable.

 

[myocardia]

Sparky, if you have your ram locked at 133, that means your power supply is too weak, assuming you have your AGP bus locked at 66mhz, and your PCI bus locked at 33mhz.

 

[INemtsev]

ON stock voltage I have it runing at 166x11

 

[SparkyJJO]

My power supply isn't weak (it is an Antec True-330) I just locked the memory down myself, I could go up to 400 and farther if I wanted, I just figure the ram probably can't go that high.

*EDIT* I just got it to 175x10 @ 1.6v ran 3Dmark03 no crashes ran some other CPU benchmarking software no crashes. Only thing is it made my heat spike from 95 degrees F (35 degrees C) to 108 F (43 C or so). At this point the ram is also running at 350MHz. I went up to 180x10 @1.7v and it wouldn't even post. I tried lowering the ram multiplier from 2 to 1.66 and it still didn't post so I know the ram speed isn't the issue there.

How high can I safely go with the voltage considering it is default at 1.5v?

 

[aka1nas]

I wouldn't worry too much about the voltage, my 1700+s are specced to run at 1.6 stock. I got them at 2000+ @ 1.5 volts at the moment.

 

[SparkyJJO]

OK. Oh BTW I got the stepping info I don't know much on how to read it maybe someone can give me pointers on the important stuff and how to read it

AXDA1700DLT3C
9820407261119
AIRGA 0250TPAW

this help?

 

[aka1nas]

Well the L in DLt3c means that the chip is raed to run at 1.5v. My chips for example are DUt3Cs, or 1.6v.

9820407261119

The 26 supposedly means that the chip was originally a 2600+ but was remarked. This doesn't really mean anything because we don't know if it was remarked because it could not run at 2600+ speeds or because AMD needed more 1700+ to ship out that day.

I heard that there may also be a number in there that tells you how many times the chip failed validation testing but I am unsure about this.

There are many t-bred stepping guides online that can give you more information about what the stepping codes mean.

AIRG"A". that means tbred A. foo. 171x10 at default?? then thats all she wrote

 

[SparkyJJO]

I thought only the T-bred-B ran at 1.5v and the T-bred-A ran at 1.6v. Guess I was mistaken.

UPDATE: I seem to have found a hole Right now I am running 175x10.5 (about 1.83GHz) @ 1.6v ran 3Dmark03 seemingly perfectly stable. Temps are about 106 degrees F right after 3Dmark - previously at 175x10 @ 1.6v it was 108-109 degrees F. Not a big difference I guess but I would have thought if they changed at all they would go up. So what does 1.83GHz average? AthlonXP 2200+ is what comes to mind.

 

[bjc112]

Definitely do not be afraid to give it 1.75V 1.8 is fine but i would not go pass that..

I have had mine @ 12x200 for over 6months now and its running rock stable at 1.79V

Vantec AeroFlow..

Give your Vdimm some extra juice also. 2.8V will only aid in stability...

 

[jjyiz28]

all tbred "a"s are 1.5 DLT

tbred "b"s come in both flavors, 1.5 DLT, and 1.6 DUT

 

[4x4expy]

If you are at 1.83ghz now, you are very near the limits of that chip. Make sure you are checking voltage via motherboard monitor or cpu-z, I would try up to about 1.75v actual.(the bios voltage setting isn't always the actual delivered voltage) Then see if you can tweak the speed up any more.
