      Glad to see some are finally take note about xIntensity I posted about way back in this thread. I have never use sgminer much at all

      and had pretty bad luck with it when I did test with it way back and since this went to neoscrypt so I didn’t put much time in trying to

      find a working version of sgminer that has xIntensity. I still have my old tweaked settings for all my AMD cards and will test those out

      soon and if there good to go I’ll post those to help others with the type of AMD cards I have on hand.

      I did try some testing with cgminer back a few weeks ago but didn’t have the neoscrypt kernel we have now to test with. ;-)

        Guys i use this miner

        and @majsta settings in my .bat file

        (280x+7950…3rd is 5850 and its off). 14.4 drivers, W7x64, 1000(gpu)/1500(mem) for both cards

        and you can see results v5vPf8Y.png

        edit:

        .bat file without --thread-concurrency got only HW…

        So you inspired me to test these settings on one of my mining rigs, which has a AMD HD 7950 (Hynix) and a AMD HD 7870 (Unknown). Here are the results:

        Using previous settings:

        Sapphire Reference AMD HD 7950 (Hynix) @ gpu-engine1100 gpu-memclock1500

        I15 g1 w64

        272 Kh/s

        AMD HD 7870 (Unknown)

        I15 g1 w64

        115.6 Kh/s

        Using new settings:

        Sapphire Reference AMD HD 7950 (Hynix) @ gpu-engine1100 gpu-memclock1500

        xI3 g2 w256 lookup-gap2 thread-concurrency8192

        327.3 Kh/s

        AMD HD 7870 (Unknown)

        xI3 g2 w64 lookup-gap2 thread-concurrency8192

        126 Kh/s

        Hash Rate Summary:

        Sapphire Reference AMD HD 7950 (Hynix): +20.2%

        AMD HD 7870: +9%

        Sapphire Vapor-X 290x (Hynix): Takes a performance hit. Traditional intensity works better.

            I believe they are going off the actual DLL versions of the files, and not using the Catalyst version like most of us do. So when they say 14.2 it is probably Catalyst 14.6 RC2 or Catalyst 14.7 RC3.

            yep, not talking about catalyst version, but actual driver version

            AMD Catalyst 14.9 (14.201.1009)

            now trying 14.9rc2, first look seems its fastest(like 0.5%)

              That’s blazing fast! Just need to find those magic settings for the 290/290x now…

                The 290x is a bit of a mystery atm. Not quite sure why an AMD HD7950 can outperform it on neoscrypt.

                  AMD hasn’t changed the OpenCL 1.2 DLLs from 14.6 Beta all the way to 14.11. I doubt there will be any speed improvements.

                  I take that back. They have changed the AMD OpenCL drivers; however, in my testing anything higher than 14.7 RC3, which uses the same OpenCL 1.2 1526.3 as 14.6 RC2, you will get HW errors trying to generate bins. This new kernel from wolf doesn’t appear to get any boost from newer drivers after the bins are created.

                    file size is not same…

                    bins now created ok, no hw erros with 14.9-14.11 catalyst

                      yeah the checksums aren’t going to match, most likely because they are re-signing the drivers on every release, which is going to end up with a different checksum every time even though versions are identical.

                        You have to remove all amd opencl DLLs from the sgminer folder.

                              try --rawintensity 6144 or 5020 or 4096, play with similar values

                                -I 14 with basic same settings as -xI 4 system has no lagged with -xI 4 very small amount with -I 14

                                  That’s not bad hash rates for a 270. From what I recall, 270 is very similar to 7850-7870. My 7950 got a 22% increase and 7870 got a 9% hash rate increase using similar settings as you. Obviously, all cards aren’t made equal, and some like these settings, and others don’t.

                                    Yes not bad but had hoped I see the same type results here with -xI like I did with LTC/Doge mining.

                                    -I 15 with those the system was unusable from lag but -xI 4 with those same settings above had zero

                                    lag with a nice jump in hash. Max OC would get just over 500kh/s per card the above relaxed settings did

                                    487Kh/s per card 24/7 for more than a year non stop.

                                    Not seeing much difference with the other -w numbers that was posted above +1 -1 is about all.

                                      I know this is off topic but what’s the best hash rates anyone can get for NVidia 750ti? Have any of these new kernals etc made any difference to NVidia cards?
