Offtopic:  For the 980TI I actually get better throughput using -i 31 than -i 31.9 (as reported poolside).  The typical job time is about .8 seconds vs 1.1-1.2 for the higher intensity.  These numbers I can see when I have a run of jobs for which it did not find a solution (don't use -q).  I am a bit more likely to find a solution meeting the difficulty requirement of the job at the higher intensity but the slower processing time lowers throughput.  This made me scratch my head more than a little bit...why the higher solve rate at the higher intensity?  But I've watched the numbers stream past for hours.  Tried -i 31.5 and it yields same results as 31.9 for throughput.

The intensity control how many hashes you compute in the gpu before work is restarted..  
In version #9 only one solution is kept and sendt to the pool. In version #7 and #8 2 solutions are sendt if found.¨

I=25

2^25= 33554432

Up to 262 144 Hashes are computed on the gpu before work is restarted.

i=31

2^26= 2147483648

Up to 16 777 216 Hashes are computed on the gpu before the work is restarted.

On low difficulty the probability of finding 2 solutions is high (since we are checking up to 16 MHASH in one go), but ccminer #9 is only sending one solution to the pool.

On low difficulties and  high intensity version #9 will only send 50% of the solutions found. On high difficulty and high intensity version #9 will send up to 100% of the solutions found, but If the gpu is too fast, the miner might be faster than the pool, and work will be lost.

I use default intensity of 29 for compute 5.0 and 30 for compute 5.2 and up

#9??? ...

sp - why are you not sending ANYTHING my way now? ...

the emails have been fixed - and you can send to the email you have on your list ...

just because i have a newbie account doesnt mean crap - especially when bct have done NOTHING in helping me with getting the chrysophylax account back ...

if you dont trust newbie accounts - fine ... send the updates to the email address you have always sent it to - and i will get it ... im NOT a fake bullshit account that is here to play ...

what gives mate? ...
