Is it okay that my processor failed an Orthos test?

I overclocked my P7350 processor to 2.5GHz at standard voltage. After an hour of Orthos, Orthos stopped because of an error (Expected 2.4, got 2.5 or something like that).

Is the overclock too much for the processor? Is the overclock safe?

 

Scratch that, I blue screened as soon as I posted that, ha ha.

I dropped the overclock to 2.1, I'll run the test again in a second.

 

Considering Orthos pushes your CPU to at or near 100% for the entire time, that's not bad. I'd say if it passes thirty minutes of Orthos without a failure you're good to go for everything except heavy encoding.

 

Yeah, 30 minutes of Orthos would be enough.

Some undervolters recommend like a full night burn through but I personally find that to be way too long. There is no way that you would ever be able to subject your laptop to that much punishment for that long of a period of time.

 

Should I be worried about the BSOD.

 

Nah, sounds like the BSoD was caused by overclocking too far. 2.5Ghz is about your limit, if you wanna feel safe, 2.4 or so should be fine ( though as noted, actually maxing out your processor for that complete amount of time is pretty hard to do without something like stress test ), just make sure your temps are good and you should be ok.

 

I think the temps, if I remember correctly, topped out at about 75C.

 

During the test, yes? That seems normal.

If a CPU ever goes over 80C, that's when you know you're doing something dangerous. I'd say that anything over 78 is getting iffy.

 

Another Orthos test failure, this time at 2.3GHz and a 1.13 undervolt.

Core 0 didn't have any errors. Orthos reports that Core 1 had a Fatal Error; rounded .5, expected less than .4. Hardware failure detected, consult stress,txt file.

Any ideas?

 

Put them at stock volt and try again.

 

I had already started to do that. I had completely forgotten about the undervolt (yeah, that's not something you want to do) until I went in to Task Scheduler to change the OC values.

I put the laptop to stock volt and went from 2.3 to 2.4, then to 2.5. All passed a fifteen minute Orthos test just fine. I then started to take the voltage down by a value of .025; right now the processor is going through Orthos at 2.5GHz with a volt of 1.175. Twenty minutes in and I'm not noticing any failures or blue screens.

My theme did change from Windows Basic for a few seconds (I was using another computer and my brother noticed it) then switched back to the theme I had been using. That's weird.

At 1.175 volts the temperature is down to 70C on Core 0 and 69C on Core 1 from 74C/73C at 1.25V after twenty minutes of Orthos. The temps have been stable for ten minutes.

 

Pretty damn good. I could never get that undervolt/overclock combo. The best stable undervolt I could get with 2.5 GHz was 1.2 volts.

The switching to Windows Basic shouldn't be a worry. That's happened to me a couple of times when I do a big resolution switch. When I had first downloaded Counter-Strike, the default was 600x400 (or thereabouts). To change the res, you have to accept, and the game will exit out and restart. During that exit, I noticed the notification that I had switched to basic.
