So.... are you saying that the rig is specifically stable based on what I wanted to do with it? I play games, too, maybe 4 hours a day and fold when I'm not at home.
Well if it is only stable with what you want to do with it, then its still not a stable OC. A 100% stable OC is when it is stable in ALL benchmarking apps and of course your specific usage of the machine.

Dont get sulky cos your engine analogy was.....rubbish.

You sir are wrong on MANY subjects. Keep your opinions to your self unless you can explain why you think all these things. The temperature at which a component is kept is the key to its life, say your stock i7 is running near its max temp threshold all the time, well it wont last nearly as long as to say a water cooled high overclocked i7 that doesnt even reach near max temps.

You just being silly now

All of which has nothing to do with that useless engine analogy and bench testing,did you read this thread or just trolling for attention?

Define many?

thats a simple one if you cant be bothered to look thru those other threads.......24hr engine tests do happen and happen a lot. Which was my point,nothing to do with watercooling,voltage or strange movements in the ley lines.....

2 hours@4.5ghz (BSOD x101)
1 hour @4.8ghz (BSOD x101)
Less than 1 hour @5.0ghz (too hot for my H70 - temp is 98c after 20 mins)

BUT..... there's a big BUT......... Stable at SMP folding.

I had it last night and told myself, let me fire up SMP folding. I maxed the SMP settings (-bigadv -smp 8) and I watched the CPU usage ran @ 100% flat for an hour (while browsing using the same rig) - no hiccups, no hangups.

Before leaving this morning, I looked on the temps running @ 4.8ghz 71~74 on all cores.

I'm expecting a comment here from the pros.
Folding != stress tests. Why?

1. You don't always fold the same projects. Some projects are more demanding on the CPU than others. Prime is a static test that runs the same routines over and over again. Simulations in FAH are not always identical (hardly ever) and therefore cannot be used as a good gauge for stability.

2. Obviously FAH employs error checking during the run and at the end of the run when the WU is submitted to the server. So even if you fold on an unstable OC, the chances that you make it to the end are slim, and if you do, there is also a chance that the FAH servers refuse to credit your work because it contains errors.

3. Folding on an unstable machine will cause you to end WUs early and those WUs which have been started already will be reassigned to another client. Part of the WU has already been completed and needs to be redone. This slows the research down as a whole. So don't fold unless you know your OC can take it (i.e stress test your machine)

Well depends which client you use. If you use the GPU client, you use the GPU more than other components.

So you might have IMC/RAM instability even while folding.

Running != stable.

Again prime95 should be run for 24 hrs so you can do both small and large FTT tests. If you can't pass 24 hrs, you are not 100% stable. 100% stable means you can run any programs as long as you want without any corruption.

Err prime95 blend tests run difference FTT sizes and length, unless you're only running a custom static test.

How would F@H error check? If it knew the outputs from the projects they wouldn't need you to fold for them? Unless they checking your results to other folders?

I think if you crunch it'll be more of a CPU/RAM test though (I still wouldn't do that without a stable system).

Ok lets think this lil different.

Lets say i oc my cpu to 4.8ghz, lets say i run 3 tests in a row.

First test - pass
Second test - pass
Thrid test - fail

What would you say for that? this is exactly what is happening to me, and i cant understand what is causing this beaviour, i know its a bit offtopic but it is strange for sure. BTW the patern is not always the same, it might be unstable on the first test but pass the other 2.

Now toughts on this,

1.The mobo has bugged LLC, sometimes work sometimes aint, which i kinda doubt, bugged BIOS? i already started for scratch, 1850 version....reflash, optimized defaults, same thing happend.

2.Vdroop? cheap electronics? i kinda doubt, after all its an ME4....but my vcore stability under load, changed a bit more then in the past, i wonder what could cause this?

3. Faulty psu to cause vdroop or voltage/oc instability? also i doubt but it could be cause...i got an Cooler Master real power pro 1000W unit.

So i'm sorry about a bit offtopic, but one could say hey your oc is not stable and thats it, but how come i was stable for whole week (every day testing) and then suddenly i cant pass the same tests with same settings...?

4. Is is possible continuos test make the system/oc unstable? your run 1 bench system is good, no errrors no BSOD, then you run 2 more and system crash? (with same stability test LINX)

What are your toughts on this guys, lets talk about oc stability in a bit different way.
