Does 30 mins orthos testing mean my OC is stable?

As title really.

I overclocked my e6420 to 2.8ghz from 2.13ghz and has done 30 mins on the orthos cpu test (go-orthos beta) and it still says "GO" is that ok?

And another thing, it says the max cpu speed is 3199mhz, when I have only ocd it to 2.8ghz - how come?

Plus I assume this is at load? If so, my load temps are 48 degrees - is this good?

Thanks guys, I really am a noob to this :)
 
My e6420 will let me know right away when it's not stable. Either I can get into windows or I can't. Don't know why I bother using orthos even.

There's a very good chance it's stable, leave it on for 8 or 12 hours to be 100% sure and see how far temps go. BTW 48 degrees is quite cool for a 65nm, what cooling you got?

Ive got a arctic cooler pro 7 thingy me bob :)
 
OR do the intel burn test for 5 rounds :)

Then use something like prime or ortho for 8 hours to test how temps go.

At least thats what I do
 
30 mins I would imagine is enough to be 95% sure its stable.. if you want to check day-to-day stability would run a couple of hours small ffts and a couple of hours blend

indeed i usually do only 30minutes or not at all during overclocking untill i reach my target speed or something i wanna stay at for a bit, run 2 hours blend and 2 hours small fft's..
 
I have had prime95 be stable for 12 hours then blue screen within a few minutes of playing CoD4. And on the other hand I have had my system be completely stable for everything except prime95....when I say stable I mean over 1 month straight of uptime doing everything from folding, to DVD encoding, to gaming, to CAD work.

I don't believe in priming at all really, I just do it for 20-30 min to see if it chucks any errors out in the beginning and to determine load temps. And sometimes I will run it for 30 min or so just because it seems to help the resale value when I'm ready to try out a new chip.

In fact CoD4 is actually the program that will tell me if the CPU is stable in the least amount of time....if the CPU is unstable I will get a crash within a few minutes.

IntelBurnTest, on the other hand...does seem very good...but the temps it chucks out scare me! lol

I've had an Opteron fail Orthos after 9 hours. I think 12 hours is often recommended as being conclusive, but some people have problems with other applications after that's passed without a problem.
 
small ffts is only going to test CPU stability.. hense why blend is also important to test RAM as well.. ofc games put different stress on different parts of the system and therefore you might want to run some 3d bench etc..

Nothing is every going to be 100% stable

Indeed, flipping between blend and small FFT is extremely useful in figuring out whether it's your RAM or CPU letting you down.

I dunno about long prime runs really, thermally induced problems are going to kick in fairly quick as CPU temp will level off after a few minutes, and the other killer, "quantum effects" as you might call them....bits flipping from 1 to 0 a bit too often (CPU's mess up in tiny ways often but auto fault correct), an electron spontaneously teleporting from one conductor rail on the die to another, that sort of thing.......all of that is just odd probabilities really, pure Dougas Adams stuff. A machine that can handle 4 cores being redlined for an hour will probably not throw a tantrum in a month normal use. And of course priming does not test all functions......a fabulous case study being my brother's machine which has primed blend and fft for 24 hrs + each without a blip, yet as soon as you throw some heavy game load or video encoding at it, it'll wait until you've gone to bed then instantly crash in any number of incredibly interesting ways, including but nowhere near limited to, wiping out and seizing/crashing every network card and hub in the house, go figure.
 
My e8400 was prime'd for 24 hours before i considered it stable, it's been rock soild ever since (nearly 4 months). The longest i've done was on a E6600 for 36 hours, but it's still no gaurantee - so i'd say leave as long as you possibly can, until your happy.
 
Personally i dont think theres much point in stressing for hours on end.

My pc crashes within about 20 seconds of orthos...

but it runs for days none stop with long gaming sessions and multi tasking. It never skips a beat. But goes pear shaped from orthos.

I say just play intensive games and run as many programs as you normally would and just relax :)
