      sgminer stable overnigt and still going

      clocks same as i used with cgminer

      -I 15 not working, some kernel error( too low memory), im using -I 14 w 48 g2 135khs

      With SGMiner, you may now set thread concurrency.

          Finally got it compiled and could test a bit :)

          Two things I noticed:

          • on a 64Bit compile the A:xxx Value in the first line of the Display reads: A:22323232343463467722132415…

          this looks like a 23bit overflow and happened on the first versions of cgminer-neoscryp, too

          • Stratum doesn’t work for me, longoll works fine

          errormessage: ‘message received: unknown method’

          I run against a p2pool, that is working fine for cgminer.

          • hashrate slightly increased on my HD 8400 GPU ( I know, I know, it’s just a laptop GPU.

            Use my SGMiner 5 compile for neoscrypt.

              earlier was 4.2.2 version, is there another outhere?

                It’s actually SG5 - the dev branch is misnamed.

                  Wolf0’s compile is a development snapshot of sgminer5. Every development snapshot of sgminer I have used has had the version as 4.2.2 even though it’s really version 5.

                  Edit: Wolf beat me to it

                    I used this link: https://github.com/sgminer-dev/sgminer

                    Do you have forked it?

                      No, that’s the link - use the develop branch.

                        That’s exactly what I did:

                        git clone --recursive -b develop git(at)github.com:sgminer-dev/sgminer.git

                        autogen.sh

                        configure

                        make all / make install

                          Odd - I have none of the issues you described.

                            can you try to mine on pool http://p2pool.neoscrypt.de:19327 ?

                            User= your wallet address or any other name

                            Pass= any

                            If you start the miner in text mode with -D and -P you will see, that the miner switches to long-poll, but does not use stratum.

                            If you force stratum with stratum+tcp://p2pool.neoscrypt.de:19327 and -fix-protocol you’ll see (or at least I see) a message ’ no pool to get work from’

                            The only difference I see for the rest of the problems is, that I have a NVidia 750ti, no AMD based card.

                              I’m using SGMiner 5 on yaamp.com right this minute. I’ll check the debug output, though.

                              Nope - I see gen_stratum_work() and all other kinds of stratum stuff.

                                and how about old cards 5800 6800 6900 series?

                                  It should run. Not gonna be great on them - the kernel code is pretty bad copy+pasted CPU code, except for what I edited, and 6xxx have hardware vectors, so they REALLY could use OpenCL-specific vector types in the kernel. Even better if you vectorize the algorithms; I haven’t thought much about Blake2S, but vectorizing salsa and chacha so that the card can execute 4 integer operations at once would be child’s play.

                                    What would it take to get you to vectorize the kernel for 6000 series cards? Pls Wolf. Pls. :)

                                      I already gave you guys something; besides, I don’t have a pre-GCN card to test on.

                                        It’s ok Wolf, you have already done so much.

                                        insanid, the official team will look into that for you I hope.

                                        Let’s see what we can do.

                                          Wolf0, and how to get 270 kh/s on 280x as you (with SG v5 on win 7/8)?

                                            Rewrite pretty much all of the kernel; also, make sure the 280X has Hynix memory - Elpida seems to do less. Then again, I only have 2 280X cards, so it could be one just sucks, too - but I’d guess it’s the memory.
