For one, it is completely unrealistic as there is ZERO chance you will ever be required to run your CPU full out for 12 hours straight. You might have a crash doing that after 5 hours (by just passing a random errata), but that doesn't mean that overclock would EVER rash in regular daily use.

In other words, you are rejecting an overclock that would work perfectly fine in a real-world scenario just because it crashed in a hypothetical scenario that would never actually happen? To me, this is foolish.

So, if your goal is to win some sort of overclocking contest, then run prime. If you are just looking for a fast desktop and gaming machine, who cares?

My rig at 180x21x3.8 might fail Prime, but it runs like hell all day real world and that's all I care about.

YMMV.

P.S., My B50 was real hinky at 3.8 when I went 200x19. However, it seems rock solid at 180x21 - who knows why? Anyway, I am benching pretty much equal to an i7 920 with this setup.
You're forgetting that Prime's whole objective is to test the ability of the CPU to perform calculations and pass data I/O without errors. It's pretty widely recognized that without testing, an unstable machine will bombard the OS with incorrect data over time, leading up to a corrupted OS and a possible complete loss of data. If you're willing to risk that, by all means do so, but don't come back here in 6 months complaining about Windows exploding.

It is absolutely in your best interest to OC to a stable setting if you plan to use it every day, not just for a suicide run.

I totally understand the purpose of Prime95, but is it necessary to run the same tests over and over for 12 hours or more? Don't you achieve stability once each test has passed two or three times?

at least in my scenario, i access my computer through RDP. I have to minimize the risk of it crashing as much as possible..well, because i can't restart it myself. I also want to have the peace of mind that my computer won't randomly crash during critical moments.

A stable OC isn't always going to stay stable, generally if it lasts 12 hours of P95 then even if it starts to go unstable you know you will have heaps of time to fix it.

And I can vouch for OCs not working over time, my chip used to be fine at 4Ghz and now I'm at 3.7Ghz. (Also, try LinX for 2 hours, much better test)

With that mentality, I would be using my system with insufficient voltages until I had major issues. If you're truly stable, it shouldn't bother you that the test is running for 12+ hours because you know it will pass.

I don't think I even need quad core. It's just nice to say I got a quad core processor for less than $100.
if your computer can run prime95 fine, then you have even less to worry about right? If it's barely teetering on the edge of stability for normal day to day things, i personally wouldn't be able to use it without being paranoid.

but then again i use my computer remotely a lot.

Alright, I will let P95 run for 12 hours. It's been running now for almost 2 1/2 and is still holding steady at 51 to 53C.

Well, there really is no RIGHT opinion regarding the prime thing. Hell, i run a RAID 0 so I cant be that concerned about things blowing up on me - lol.

I guess my point is that there are MANY reasons Prime could crash you after 5 hours BESIDES your overclock being bad. I just can't see how running your CPU full out for hours on end does anything but wear out ur CPU.

But I'm not gonna throw away a sweet, fast, functioning OC just because it crashed after beating it senseless for 7 hours. Of course, you may feel differently and that is fine. Just a matter of taste IMHO.

MY REQUIREMENTS FOR AN OVERCLOCK:
1. Boots Windows.
2. Runs my desktop apps.
3. Plays games full out.
4. Doesn't crash while I am doing 1-3.

For me, anything more than that is overkill.

12 is ok.... 24 is better.

Out of curiousity, what is the approximate overclock/core unlock success rate upon running P95 for 12 or 24 hours?
