How come no one talks about CPU degradation? My 920 D0 is degrading. - Page 13

Certainly sorry to hear you've had a bad experience.

I do agree with you that there are a worrying number of people who jump into overclocking seemingly without having read anything about it.

Some part of me often wonders how many systems meet their end at first time overclockers who can't post to tell about it because they're nursing a lump of metal that used to be their computer.

Sounds to me like its your motherboard or RAM. The CPU certainly isn't degraded. And just because you ran Memtest for 18 hours, doesn't mean jack squat. Memtest isn't a memory stability test, it just checks for errors. That's it.

Run P95 the following way:
Check "Blended" so the blended settings are set. Do NOT hit start.
Now, move to "Custom". Adjust the Memory to Use section to use 3/4 of your memory.
Now start it up.
Let run for at least 10 hours (it takes around 10 hours to pass through all of the tests).

If that works, then you're fine and stable. If that doesn't work, then tinker with your memory. I'll bet on it that its your memory giving you problems, since it doesn't seem like you have EVER stressed your memory much.

it could just be your room temp changing...
my OC is unstable in summer because my room temp is about 15C higher

11 years? According to this the Athlon XP 1700+ "Palomino" was released on October 9, 2001. And Athlon XP "Thoroughbred A/B" at later date/year.

Did you follow my earlier suggestion? I see you have turned LLC on Auto and used speed step. You should really try one thing at a time to isolate things... Do not activate Speed step before you have sorted out other things.. And your goal was to see if you could make your CPU stable at your previous stable voltages, so leave that LLC for now.

As I've said, relax mem timings (I see you did that and also the other things), try IBT again, at your previous stable Voltages/clock frequency. Run memtest for Windows, four sessions. Each session/windows with 2750MB RAM. See if they can run error free at least one round.

Welcome to overclocking.

This happens.

Deal with it. We all accept the risks. Hell, I run my chip way hotter than you do, and I'm fine knowing I might be pushing it a little too hard, because by the time it dies, the next big chip will be out. I love my proc, but we're all playing a dangerous game with them. There's a reason overclocking voids warranties.

Depending on your board/CPU, your OC may or may not be able to make the transitions that EIST applies. It's not guarantied, and that's why you disable it when you start to OC.

I have 4 pretty aggressively overclocked systems, two can use EIST, and two have random crashes if enabled. Only one can use EIST AND enter/exit sleep mode, the Q6600. You try and tweak it AFTER you have a stable OC, there is no possible reason to use it to STABILIZE an OC.

Cmon man, it's at the beginning of every OC guide since it was introduced.

Yeah. "common knowledge" that is commonly misunderstood. If you have an OC that cannot deal with EIST being on then I contend the OC is not stable and not a good OC to run 24/7. Running with EIST disabled is akin to having your car idle with the engine RPM running as if you were driving on the freeway. You are wasting power and needlessly stressing your system. Many people who come on here read the OC guide and take everything as gospel. For example, how many BIOS screenshots do we see where people adjust thier clockskew to whatever is in the guide? Did they really need to make that adjustment? or did they just change it in their BIOS without even trying to get a stable OC without messing with the clock skew?

I think the misunderstanding comes from an unclear understanding of the purpose of the OC to begin with. There is a difference between overclocking for CPU-Z validation, for example and an OC for everyday 24/7 use. Yeah, I can OC my sig rig to 4800 MHz, and provide CPU-Z proof when I disable a bunch of features in the BIOS, but an everyday overclock SHOULD be stable with EIST enabled, LLC enabled, etc. etc. otherwise it's just a "validation" OC and not suitable for a 24/7 OC. I think that is where a lot of mistakes and misunderstandings occur. People think a "good" 24/7 OC should not have EIST on because they read it in the OC guide, therefore it must be how I should run my system.

Not good.

How many 24/7 OC machines have you built? I have overclocked P3s and Athlon XPs running 24/7 still at friend's/family homes, and they had no cool-n-quiet or EIST. Are they not stable?

As far as cool-n-quiet and EIST goes, some can run it, some can't. The ones that can't run 24/7 without a problem. I guess I'm just gifted.

This seems unrealistic to me. If you wanted the cpu to last that long, doing a 4+Ghz overclock is probably just asking for problems down the road. Most people swap out their chips in 3 years or less so they aren't that worried about longterm damage. If you didn't have it set up you should enable downclocking during periods of inactivity, it would help with the longterm life of your chip, but might require you to be less aggressive in your OC.

As an example I know that a 3.5Ghz OC on my current CPU is nearing it's stability limit, but I also plan to swap it out in a year or so...

Edit I haven't read this entire thread so if anything's been stated and this post is redundant/unhelpful I apologize.
