Orthos stable.... not much else?

So I tried overclocking a bit further today. Rig in sig. My stable overclock is 9.5x290, only a one notch bump in vcore, but past that doesn't work. Actually usually past that is BSOD's. But today I loaded up at 9.5x300 (usually BSOD's and lockups), at 1.375 vcore (1.3 default). Orthos was running stable fine for over half an hour, blend and small fft's, but the funny thing was that internet explorer, winamp, even windows live messenger were all crashing! This never happens at my stable overclock.

Obviously, since I have it back at a stable overclock I've been fine, but I found this strange.... anyone else ever seen this happen? Orthos was stable....
 
Half hour of Orthos doesn't prove stability.

It does sound like an unstable OC, try raising the voltage a bit more.

Also, make sure it's not your memory the one that's unstable.

And watch your temps.
 
I have a Pentium D 805 and ive gotten to the 3.4Ghz mark on HSF, ran Orthos for 3 hours and nothing...everything works fine. But my temps were rather high. 70+. Now i set it to 3.00Ghz and ran Orthos for 8 hours straight. Still stable and highest temp it hit was around 70C MAX. Not one hiccup. I still feel uneasy running my D805 at 3.4Ghz...also i did all this without upping the vCore.
 
Well which Orthos were you running? I always run blend because if you get 8 hours at blend you know your mem+Cpu is stable. 30 min does not equal stable.

Run blend for 8 hours and if you can I bet the other stuff will not crash.
 
in orthos using blend is a good idea. but using small fft's can give you a better idea of cpu stability and temps.
 
Im not saying that 30 minutes = stability... I would have left it for 8 hours at least, what I was saying was that even with Orthos running, you can still WORK on the computer without having other programs crashing, getting errors, etc., which does NOT happen at my known stable settings. I just ran 290x9.5 with a little tighter RAM sub-timings and have been using the computer for the last 2 hours, web-surfing, working, etc. Nothing went wrong.

So maybe I should have let it run longer, but I was curious... can you start getting instability errors on your computer while running Orthos... but still be Orthos stable?

the short answer is yes. however, you could run orthos for eight hours perfectly fine, but if programs are crashing left and right, than your overclock is far from stable.

I agree to the extent that when I start out I use small ffts to get an idea of my cpu limit. Once I know how far I can take it I always switch to blend to get my 24/7 settings. Usually they are at a lower FSB then I get with small ffts.

Also the temps even in blend are way higher then any game or stress that normal PC operation can place on the cpu. I have yet to find something that comes close to it temp wise. Running loops of 3dmark certainly does not come close or any game. So thats why I prefer blend once I get my cpu limit.
 
Just bump up the vcore a bit. Sounds like it's not getting enough juice. Try priority level 8 for orthos, that is usually the most unstable for me if clocks are too high. And orthos blend for 10 hours dosn't meen the memory is fine! I could run the blend or large ffts for 10 hours+ but got random crashes, reboots and error messages with just about every overclock level. Turned out that I had a bad memory chip, replaced it and now everything runs smooth as butter. :)
 
Just don't use your PC while Orthos is running. It might not be an OC instability problem, it might be that those apps have problems with Orthos. For example, for some reason, if I leave CoreTemp open for a long time while Orthos is running I get an error. I don't know why, but CoreTemp and Orthos in my PC, don't get along, even at stock speeds.

So, just close all other programs, leave Orthos running overnight and don't use your PC while it's running. If you get through 7~8hrs of Orthos without problems, then your OC is stable in spite of the fact that other apps crash particularly when Orthos is up and running.

PS. if you want a good alternative to Orthos, try OCCT. I like better than Orthos.

I would tend to agree with you, but I came back after 6 hours of my stable overclock Orthos blend and small fft's, ran internet explorer, worked, etc etc and it was completely fine, no crashing, etc.

I think I'll try upping the vcore some more. Maybe I can get some more out of it, just see how hot it runs idle....
