OK, you're not wrong; nor am I. It appears you are, by far, the most productive DCTF'er to 72 currently! Thanks! :smile:

When you add on the 14 that the GTX-660 also churns through that's 46 a day..isn't anyone else doing any?

A few others are, but you're by far the largest producer (to 72) at the moment.

Keep in mind also that when I do the "Days Ahead" projections, I use the average production over the last 30 days; over the last five days we've averaged 58.2 a day.

You can roughly see who is doing what by looking at the [url=http://www.gpu72.com/reports/workers/dctf/]DCTF Workers' Progress[/url] page. Divide the GHz-d of work by the number of assignments. Roughly, 3 is to 70, 6 is to 71, and 12 is to 72.

Thanks for pointing that out Mark. Also, another useful report is [URL="http://www.gpu72.com/reports/workers/dctf/week/"]the DCTF Worker's Progress over the last Week[/URL].

BTW Gordon, you're Factors Found vs Attempts ratio is a little low (but not beyond reasonableness). Probably just bad luck (someone else getting your factors! :wink:), but have you run the mfaktc full self-test on your cards recently, just as a precaution?

These are the 2 I use for my weekly/monthly progress reports

Yet another page I was unaware of :)

Since I switched to LL-TF to 75 bits I have a hit ratio of 3 / 282.
Seems low but is it unreasonable?

Well, mine is even poorer with 2/625 at TF 75...
8/375 TF 74

Those results are a mixture from 3 different cards

Palit GTX-660
Gigabyte GTX-660
Gigabyte GTX-970

Just out of curiosity I am running a -ST2 test on the 970 right now.

I spent a couple of weeks recently running factoring on exponents up in the 970m+ range and was finding a factor roughly every 60 or so tests, took the 660 7 seconds to go from 66-67 bits.

Didn't I read somewhere on here that as bit depth increases, odds of finding a factor decrease? Or is my memory playing up again...
