unlocked x3 740 @ 3.72 CPU and 2.79 NB got it 11h21m P95 stable for everyday use

post #1 of 7
Thread Starter 
I have my 24/7 setup for now.

I've been running this for a while but hadn't done a long run. I had a few P95 runs fail around the same place ~3h30, so today I upped the CPU/NB a bit more and let it run, and at the end I was watching a movie, and the weakest link, the 2nd worker and its part of the CPU/NB failed.

So in a custom blend using 2800MB of RAM, it lasted 11h22m



CPU is at 1.4625V, lower and I seem to get a BSOD and then reset around +5hours in



CNP/NB at 1.478125V, 2 steps lower and I was getting the same 2nd worker fail around +3hours

The RAM is at 1.625V, I need to find their lower limit in this setup.



(I didn't notice you can't see where the 2nd worker failed 1m before I stopped it.)

Temps where about 52C most all day.



Lots more fun yet, even with this small cooler.

Amazing
1.625V is actually slightly above the point where most G.Skill ECO stops scaling well with voltage... perhaps you got Elpida BBSE-binned ICs? Try 6-7-6?

Whew nice.
I had mine unlocked at 3.5Ghz @ X4, voltage around 1.52...maybe 1.55.
Most the time I had it I ran it at 3.6 - 3.7Ghz @ X3.

Used a 770-G45.
Was a great little board, 4th core wouldn't pass some of the harder CPU burns but darn close, very stable for games and multitasking.

From heka to deneb. It's a great thing.

Icant get mine passed 3.6ghx at 1.55v nb at 2700. whats your secret?

My 720 BE hits a wall around 3.6Ghz for stability as well. I can suicide at 3.7Ghz on this 940 BE cooler but that's it. This is just X3 as its not stable even to boot at stock on X4.

I haven't tried much at stock 7-8-7 settings, but so far I can't get the NB much above 2800 on this 310 FSB, and 310x12.5 doesn't seem to work at all.

I posted a +4GHz setting a while back, windows could run, and the internet, P95 would cause immediate BSOD and reboot, temperatures were an issues in that session of experiments.

So there are many settings I haven't tried enough yet.
