Actually, the 7770 should finish an unblanked AP in under an hour. My 7750 finishes one in just over an hour. My older 6770 takes about 1.25 hours. Since there are APs about, I'd change the preferences to ask for AP only and grab a few. I use a setting of -unroll 10 -ffa_block 8192 -ffa_block_fetch 4096 -sbs 256 to bring the GPU load up to around 90%. It's in the AP readme. My cards usually finish a 90+% blanked AP faster than the one AP you completed. It would be interesting to see a few more APs run on the 7770.

I have a text file in my seti directory named ap_cmdline_win_x86_SSE2_OpenCL_ATI.txt

Would this be the place to put your suggestion of "-unroll 10 -ffa_block 8192 -ffa_block_fetch 4096 -sbs 256" ?

I recall recently adding -sbs 256 for an MB text file in the same directory, from someone's suggestion. (mb_cmdline_win_x86_SSE_OpenCL_ATi_HD5 was the name of the file).

This sounds very similar, but just for AP instead of MB?

Yes, that would be the file. You may need to increase it to -unroll 12 -ffa_block 8192 -ffa_block_fetch 4096 -sbs 256 to achieve 90+% GPU Load. Check the load with GPU-Z. To run the AP immediately, sort by Application, select all ATI tasks except the targeted AP task, suspend the selected tasks. Once the AP begins to run, resume the still selected tasks. You better hurry though, it looks as though the APs are about to disappear again.

Thanks, got it. My ATI GPU seems to be configured to run 2 APs at a time. Will the command line instructions you suggest work in this scenario, or are those instructions meant for 1 AP only?

Also, is one free core all that is needed for ATI GPU? I have one free as this is going now, with two AP tasks.

For both questions - see for yourself.

Do you feel lag? (if so make -unroll smaller e.g. -unroll 5)
What is the GPU load? (in SIV or GPU-Z) (if low <85-90% or too unstable - free more cores or try higher -unroll 12)

Running with one free core will work until you begin to run two APs that are heavily Blanked. You will then Need Two Free Cores. The idea behind the Settings is the same as the idea of running two tasks at once. Both are meant to raise the GPU load to near 100%. Usually, you don't need Both methods. Since running Two tasks requires Two free cores, some times that is not an option. An example would be running on a dual core processor, such as two of my Hosts. If I use both cores for the ATI card, there would be nothing left for the nVidia card, or the one CPU task I run. If CPU-Z shows the load pegged, I suggest you back off on the setting or run One ATI task at a time.

Thanks everyone for the information.

I did two AP tasks last night, at the same time.

Task 1 Run time 6,923.63

Task 2 Run time 8,393.97

Not sure if these are great, but they do certainly seem to be the fastest AP's I've ever ran!

AP runtimes depend on blanking. Try to compare similar values.
