    750ti are less power hungry tho?

      does -g 3 -I 17 work, or throwing back HW errors, anyone tried those settings?

          -g 2, 3 crashes the miner here

          lizhi, you are correct. High tread concurrency was the cause

            Wellenreiter, do we need external help with the stratum? Do you think it would increase productivity?

            I can get my 550M to work up to I-13 without HW. -I 12 and -I 13 make little difference tho.

            I hate to say it but it seems the 7850 has the edge over 750ti productivty wise while at same price… :( Tho I am not sure if lizhi had aggressive overclock or its just too hot in China :D - 86C

            What temps are you getting with the 750ti ? Have you tried I-13 ?

            Help with stratum would be really appreciated. My actual code is on github: https://github.com/wellenreiter01/p2pool-neoscrypt

            I can add anybody to the repository who want to help.

            I tested with minerd from Ghostlander and the hash calculated by the pool is always 2 byte too long when using stratum. Longpoll works fine.

            Didn’t check my GPU temp, as the fans are running low speed it can’t be too high.

            The NVIDIA cards are slower than the AMD card with opencl based miners.

            I hope for Cudaminer to be adapted.

            That should boost the performance of the cards.

              You all keep mentioning Nvidia cards. Is neo better run on those or is AMD still dominant? I ask because I have 3 rigs full of 7950’s that Im holding off on selling to mine feather once the algo is changed. :)

              I want to setup one on the test pool this weekend if I have time.

                The openCl gpu miner seems to run better on nvidia cards but if/when there is a cudaminer (nvidia specific) they should be pretty even. Nvidia cards generally use less power and are not as hot but you don’t get as high a hashrate so its swings and roundabouts really.

                  folks, check this out https://github.com/ahmedbodi/stratum-mining-multialgo it claims to support stratum for neoscrypt

                    unfortunately this can’t be adapted easily to p2pool.

                      Where is the source for this. Love to help.

                      I have a bunch of GPS’s i can throw at this.

                        that would be GPUs not GPSs

                        sigh

                          this has not been modified in months

                          only looks like cpu neoscyrpt at best.

                          other cpu miners available if wanted .

                              My p2pool is running normally. >:D That is not too many connections .

                              There are 3 connections in wallet, 1 miner connect p2pool.

                                Hi all, How is Pheonixcoin getting on with the change? I have got 6 Cores dedicated to mining Neoscrypt and i have mined over 1000PXC in 5 days.

                                All seems to be working OK but i’m unsure of its effect on value / community.

                                Is there any reason we have to wait for an efficient GPU miner before changing FTC to Neo?

                                Just worried there is a scary amount of Scrypt ASIC out there at the moment and i know of a few people with over 10000Mh of Scrypt, couldnt they do a lot of damage to FTC if they wanted?

                                Thanks

                                  Work is continuing on a daily basis on the GPU miner, once it is ready we can switch over fairly quickly, the consensus is we don’t want to switch until the GPU miner is ready for release, but hopefully that won’t be too far away.

                                    What are you pulling out of the six core? Can you tell what cpu model that is exactly

                                      Yeah sure, im using a Dual Quad core Server and using 6 of the 8 CPUs to mine (other 2 are idle)
