You do know that gaming is not a form of stability testing right ? I have gamed for bloody hours with no issue and then BAM trying something like folding and BSOD. There are activities you can get away with when you have an unstable OC and some you cannot. All in all it means you are not stable.

No offence but any worthy overclocker tests for stability. Nobody just ''Know what to expect from certain chips'' If you are meaning just one then I could forgive that statement but I think you mean a few more than just one. EVERY CPU is different, whether they are the same family of CPU or not.

Lol?

I'm using a Q9550 @3.6Ghz which runs fine at Prime95 and LinX, but OCCT gives errors. Quite strange, while folding@home runs perfectly fine. Good for me.

If you ran prime95 for the full 24 hrs and passed but fail OCCT it might be a heat issue.

OCCT pushes your CPU about 4-5 degrees hotter so you might be hitting a thermal wall. And the rest isn't directed at you.

Again prime95 isn't just for stability, its for data/computation integrity. I want to know my CPU will do math correctly all the time. The readme even says a full 24 hr pass is recommended.

Folding is not a stability test in any form. You run it after you stabilize your system.

If you're not working with critical files than its fine (you're only hurting yourself).

If you fold, you better know the math is right or you're just making things worse.

Seriously if you can fold for days, why can't you just run prime95 for 1-2 days to just make sure you're sending good information? Bad data is useless or may even be harmful.

but, the guys that fold do need perfectly stable CPUs.
I actually use F@H for stressing my clocks when I change them.

Can I beg to disagree on the folding part? With an exception based on my current rig in my sig. I can never pass 12 hours of Prime95 (blend) @ 4.5/4.8/5.0 and the longest was;

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 is not a test of stability. However due to its nature of being very sensitive to some types of Clock instabilities you can sometimes easily tell if you are unstable. Like I said with my post above, some things you can get away with and some things you cannot.

What comment do you want from the Pro's ? lol

You know... common knowledge that we share here

I mean something that I still didn't know or maybe missed doing


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.

Are you prime95 stable at stock? If you are, I would say you have a slight instability.

prime95 checks the output, so if you have a computation error it'll catch it.

IBT and other stress testing programs doesn't compare outputs (unless you're manually comparing prime numbers from IBT).

F@H doesn't have a check for data integrity/computation so you could be sending bad information.

Seriously I don't understand why people would be willing to accept OC's that are stable only on certain stress testing programs. If it isn't stable on all programs for the recommended time it isn't truly stable.

Again prime95 does small FTT tests for the first 12 hrs and large FTTS after 12 hrs which is why its recommended for a full 24 hr pass.
