Looks like this huge WU got only 28 hours of crunching. If it will be succesfully completed, I'll be a happy owner of a highly overclocked CPU.
Yesterday we (I am with my friend) found an article on overclockers.ru about an extreme Core2 E6750 overclocking and tried this ourselves. So E@H became yesterday out test application. So, we're waiting for result to be accepted or (unfortunally) rejected by the server side.
At least on Core 2 CPUs, it seems that if the Einstein science application does not detect error during execution, the chances that an over-clocking induced error will cause failure to validate are quite small. So on this first result I think you are very likely OK.
However, the maximum clock speed a given host could run Einstein has moved around with application version in the past. So if you are anywhere near the edge, be sure to monitor your outcomes for a week or two after any application change.
For both of my Core 2 machines (A duo E6600 and a Quad Q6600, both running 3.006 GHz), the current 4.40 Einstein Windows ap is materially easier vs. clock speed than was the current ap a few months ago. This could easily change the other way next time.
Oh, and one good result is not enough to establish that you are at a safe operating point--I had to raise my voltage a couple more increments above the level that was OK for 24 hours before I became OK for months.
The above result is from my wingman (who recently reported on this WU). This "monster" produced 653.02 points for us - not particularly noteworthy. But, I certainly think my wingman deserves recognition on this thread for the time it took his computer to finish the job: a collosal 2,017,980.08 seconds. (I really think something must have gone wrong with his result.)
I got 643.26 for this one

Your results, of course, may vary.

Nice one... and not even THAT

Nice one... and not even THAT fast a box, or are the benchmarks mistaken?
RE: Nice one... and not

Speaking of "not so fast", my vintage T-Bird Athlon 800 just got hit by monsters ... oh well.

I'll keep my fingers crossed for the box to finish in time...
RE: I'll keep my fingers

Thanks! It will have no problem to finish provided I don't forget to turn it on again each morning...it's too noisy to stay on at night :-)
All but one of my crunchers now have at least one monster in the pipeline, but none record breaking, tho.
