OC Q8300 from 2.50GHz to 3.56GHz on Air

Hey everyone, just a quick question. I've been overclocking my cpu recently a bit more than what I had it running at before.

Everything appears to be 100% stable. I would just like a second opinion on my stats to make sure im not going to be doing any damage. My vcore is mid high but from what i've read, up to 1.4 is safe....

Just to let you know full load temps doesn't work like that, you really cant say your computer is on full load temps when all cores are 100% (running Prime/OCCT for 10secs). You should wait a minimum of 1hour to really see what your real full-load temps are.

To answer your question, your IDLE temps are good, can't really answer your full load cuz I don't know it.

Voltage seems alright. I reach 3.6GHz with my Q9450 at 1.29V and 3.8Ghz at 1.33V.

Given how the Q8300 is a lower-bin processor, looks like your voltages are right where they need to be. I agree with Dork, you need to load the PC for at least an hour with specialized software.

Gaming doesn't qualify - at most you'll load the CPU to 60% with the heaviest games. You need raw math. :rtfm:

Use the latest OCCT. That uses Linpack which is far more stressful than Prime95. And run it for at least 1 hour before considering stability/temperatures.

At least 6h of Linpack would be 100% stable to me. For Prime95, I'd say closer to 24h and even still, some people report that Linpack will fail even though Prime95 works forever.

Use ONLY OCCT to stress test. Don't run OCCT and Prime at the same time since it won't help you effectively find your stable overclock and load temps. Also, wait at least 5 to 10 min before you figure out what the load temps are.

Im sorry to bump this thread, but I am sitting on the same setup as you and I was just
wondering if you could post your BIOS settings for this setup.
That would make me very happy :thumb:

Hehe, unfortunately I just sent my P5Q-Pro away this morning. I don't remember off hand what my FSB rating was set at. Look at the last few posts and you can get my multiplier/fsb speeds from the cpuid screenshots.

That's too bad, I can just get my stable at 3,4ghz (12 hours prime) with 1,36v during load.
But I have a VID of 1,2375 so that maybe why :sad:
