Nice GPU load on 36,666,666!
See attached screenshot
Nice, around speed of GTX 680. I would be curious to see at "stock clocks(OC)" as well, if you want.

Indeed, not bad for a card that costs €50 less!
Sure!

Default LL territory test
Tested the first 20000 iter of M63300049 as a test for LL territory speed , since it has a factor anyway .
Code:
clLucas_x64_test-1.0>clLucas_x64.exe 63300049
Platform :Advanced Micro Devices, Inc.
Device 0 : Tahiti

start M63300049 fft length = 3276800
err = 0.355469, increasing n from 3276800

start M63300049 fft length = 3538944
Iteration 10000 M( 63300049 )C, 0x3c0d0358c14611b9, n = 3538944, clLucas v1.00 err = 0.1953 (3:09 real, 18.9353 ms/iter, ETA 332:53:33)
Iteration 20000 M( 63300049 )C, 0xfe91586583ff04b5, n = 3538944, clLucas v1.00 err = 0.1953 (3:09 real, 18.9264 ms/iter, ETA 332:41:02)

That is not the probably full "possible" speed I believe, ask msft.
Also,
Code:
M( 86243 )P, n = 4608, clLucas v1.00
M( 110503 )P, n = 6144, clLucas v1.00
M( 132049 )P, n = 6912, clLucas v1.00
M( 216091 )P, n = 12288, clLucas v1.00
M( 756839 )P, n = 40960, clLucas v1.00
M( 859433 )P, n = 49152, clLucas v1.00
M( 1398269 )P, n = 73728, clLucas v1.00
M( 1257787 )P, n = 65536, clLucas v1.00
M( 2976221 )P, n = 163840, clLucas v1.00
M( 3021377 )P, n = 163840, clLucas v1.00

Ok, played with it, but the result is very odd! When the CPU is fully booked, the clLucas is... faster! No joke, and there is no mistake with the red text in the attached photo.

The 7990 is even slower, for a less occupancy. I might need to launch two instances to max the card... I will try this later.

Making an analogy with gtx580 (I don't think it is appropriate, but for the sake of example), when the occupancy of the GPU is 99%, the speed is almost double comparing with occupancy of 84%. Should we expect something like that on Radeons too? (assuming I might be able and enough clever to supply the right parameters, number of threads, FFT size, etc)

(P.S. @kracker related to PM: don't push me, you don't know what you are up against! I didn't do DCs for ages, but just wait few weeks till I am back from a biz trip)

At this point, I think most people know that you are a maniac, and not to be trifled with. Next thing we know, you would be setting up a liquid He2 loop, or something.
