My first ever OC

I've always been terrified of the thought of OCing, but I couldn't resist getting an e2180 for $80 and giving it a whirl. I've got some decent cooling, nothing overly special (Arctic 7 pro), but I'm really impressed. I had the vcore as high as 1.45 when I was trying to get to 3.0ghz stable, but it seems I didn't get the best chip of the bunch.

I'm running Prime95 right now at 2.8ghz and it seems stable (@1.3875vcore) running ~53 celsius which I find amazing as I'm living in Florida and my dad doesn't like using the air conditioning (room temp is at best 80F. Can't wait until I go back to school in a week where I keep it a comfortable 70 degrees.

Anyway, I have the memory voltage pumped up, and the timings are pretty low at the moment. It's Corsair XMS2, and I've got a Gigabyte P35-DSRL. I've got a fan on the northbridge because I hear it got hot. I'd really like to get 3.0ghz stable, it's sort of the mark I set for myself. Is the FSB supposed to not go over 1333 on this motherboard? I'm a little confused about that. And I don't really understand the memory timing ratio thing. That still confuses me.

The chip doesn't seem to be cooperating though.If it holds stable at 2.8ghz I can't complain (40% OC!). I'm addicted to cooling and OCing now, I've been up since midnight and it's 5:39 AM, haha. If anyone has any idea, I'd like to know. The closest I got to 3.0ghz was 1.45vcore 9x333. Prime95 ran for about 30minutes, and then the computer rebooted, Prime didn't fail. It was interesting.One thing I've noticed that doesn't seem to be in line with what others has noted, is that when my vcore is upped from 1.35 to 1.45 the temperature during the stress test increases just 3-4 degrees on average farenheit (53 to 57C or so). I won't complain though, heh.

Also, what are some good benchmarks that tests strictly CPU performance? I don't have the best graphics card in here yet (I'm saving for a 9600gt/8800gt I think). I want to test this little warrior against some of his c2d counterparts.
 
Go turn on superpi and do a 1M digits of pi test. Go look and compare online. I got 17 seconds personally with the rig in the sig.

2.8, that voltage, and those temps are pretty good.

What is your Bus and multiplier? Are you just doing 280 bus, 10x multi? Try a 400 bus, 8 multi.

Increasing the northbridge voltage can also help.
 
I get 22seconds on SuperPi 1mil.

I'm running 10x280. How would you increase northbridge voltage on this motherboard? I don't see northbridge even mentioned anywhere, heh.

Is there a way to get the temperature of the northbridge?
 
Some motherboards come with a northbridge sensor.

Yea, go play around with different multipliers and buses. 350x9, 400x8, etc. Try to find the max bus for each multiplier. 7 maybe, but defiantly 8 and 9.
 
Tried 8x400 earlier and I couldn't get it to load Windows, heh.

9x333 was going well. Any idea what would cause the computer to shut itself down about 30mins into prime95 testing? The heat wasn't in issue, it got to the upper 50s tops.
