How Many Passes of IBT would you do to deem a CPU OC Stable?

post #1 of 14
Thread Starter 
I'm just wondering about how many passes, as the title suggests.
I'm in the process of working my processor to 4.0GHz, and I'm just curious as to what OCN recommends.

How long do 50 passes take?

I was 10 passes of IBT and 12 hours of prime blend stable @ 3.7ghz but I just OCed my northbridge by another multiplier and had to up the volts a little so I am retesting the stablility. I am 11 hours into prime now so I figure it is stable but I just want to make sure and IBT runs go pretty fast. I am just screwing around with my Phenom II right now with my new cooler until my sandy bridge parts come next week.

One run takes about 300 seconds for me with 8 GB of Ram. 50 Runs takes about 250 Minutes (less than 5 hours).

No, 20 minutes isn't nearly enough.

Some due, some don't. Personally, i stick with prime95 to make sure that i have stability for permanent oc's. And use 20 runs for benchable OCs.

Hey guys, OP here. I'm having a curious problem. My previous stable OC of 3.7GHz is deciding to die on me. It was Prime95 stable for about 8 hours and IBT stable for 10 passes on high.

I kept getting 0x0000124, 0x000001E and an amalgam of other errors, but setting it back to stock has it all going just peachy. However, I'd like to get it back to 3.7GHz. Any ideas on where it's deciding to screw up?

CPU-Z's going all funky on me now as well. It says I have a 25x multi on my Processor despite it all being on stock. CoreTemp on the other hand reports it as 18.5x
