P4 3.2E D0 stepping fragile?

[Juice]

I was testing the limits of this chip. I was running a few instances of SuperPi with 4.2GHz clocks and decided to run higher and pushed it to 4.3GHz and then 4.4GHz but it then showed a BSOD and with a message 'Windows has shutdown due to an unknown error' or something like that... That's the first time I've seen it do that. It usually just reboots whenever I've reached the limit of the overclock.

I rebooted and added a few volts to the vcore. It was doing fine at 4GHz with 1.44v on the bios sensors. So I added a few volts to around 1.48volts. Then exit. When the reboot cycle began, The Abit alarm went off. Signaling that the overclock was not acceptable. So I reset the normal overclocks I used. I put it back to 1.44v and 250 FSB which gives me 4GHz which is my usual startup. But the alarm was still sounding off. To make this short, I have to push the vcore higher than usual to get to 4GHz now. I'm beggining to think this stepping is fragile. Anyone care to share or speculate what could have caused this? too much vcore?

oh oh... i smell psds... not good. the least intel can need now.

what are your temps? are you 100% sure you need more vcore than before? how much? what was the highest vcore you tried?

[enzoR]

WOW.... yup, PSDS.. i hope AMD wont have the same prob with .09

[Crankster]

What is PSDS??

[Juice]

I've only tesed this up to 1.5v. I always run at 4GHz but only with 1.44v cause it's been always stable with that settings. Making it 1.48v was still fine for me since i've tried 1.5v before. I wonder why it did that only now? My temps are CPU 6c(bios sensor) when it happened.

What is PSDS??

I think it might come from "PRESCOTT SUDDEN DEATH SYNDROME"

[cpulloverclock]

My 3.4E D0 hasn't this problem

weird

Prescott Sudden Death Syndrome...?

What kind of cooling do you have on that Prescott? What MOBO?
I don't think you gave it too much voltage. I have read that the most you can safely give pressys on air is 1.525 and 1.550 on water, some people have given them more (1.60).

in air 1.6v like in wc (1.60-1.63v)
with my vapo about 1.80v

[saaya]

did you flash your bios? some manufacturers have locked the higher vcore options or made the system reject those settings.

and i know the original prescott stepping DID die from too much volts. hellowens prescott died with 1.7v even though it was at -100C under load!

so 1.6v on water should be ok.... SHOULD... it could be that your mainboard has a defective pmw and is giving too high voltage spikes to your cpu wich demages it. can you check it with a multimeter? but if the pmw would be damaged you shouldnt be able to oc that high... weird

Is that 24/7? If so, How long have you had it like that?

Juice you should check your voltages like saaya said. Use a DMM.

Good luck!

[saaya]

woa redken, your sig hurts my eyes!

[REDKEN]

lol
It looks ok on other forums. On this one it takes a different shade of green.

of course 24/24 365/365

I have nothing but repect for you. I don't mean this as a flame or a put down. I hope like heck it doesn't get me banned but this line-->oh oh... i smell psds... not good. is pure BS!

There's a big difference in abuse and normal use. SNDS when folks going higher than 1.7v even after Intel warned them not too is even Dumber. So would I call it SADS if I ran an Athlon64 without a Heatsink, or have four of em' die (burn up) like on that other thread? From just being pushed too hard?

is an internal wind error, I had that few times today while trying to score 28" at superpii,I think nothing to worry about.

I have the 1.44v on every boot up or normal use. I only tried the 1.48 to see if I can get pass 4.3GHz cause I know my OCZs can do 275FSB So I only pushed the vcore. I'm confused cause I had a 2.6C run 24/7 with 1.75 Vcore which did degrade after a couple of months with high voltage. But this Prescott only had a few minutes of high vcore, which isn't really that high. I had a 2.8E with much higher voltage than this going 1.6 and higher. I'm using a VapoPE by the way.

[REDKEN]

What motherboard are you using?

[Juice]

I'm using an IC7 MAX3 unmodded.

[REDKEN]

How high can you O/C your CPU using the lowest RAM Divider?
I don't know much about the IC7 MAX3. You could ask around to see if the Vcore is linked to the NB volts on your board.

Good luck on this.

[Romaster]

what stepping?

[detonator]

boo is strenge....

With 5:4 I can go 4.3Ghz only same as 1:1

Romaster, its a D0 stepping SL7KC

[Romaster]

ah a sl7kc.. like my own..
anyhow relating to your volt problem.. there are rumors that presshots sometimes get degraded with certain amount of volts.. the sl7kc as well as any presscott can suffer this same issue.. it varies with luck really and not with temps..

[Juice]

Thanks for the info Romaster. May I ask how high your vcore is and what clocks are you running at 24/7?
