      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.

        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

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

        thanks

          thanks

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

          Please see attached :

            6 cores (12 threads) of Xeon X5660 3.1GHz pull out 25KH/s.

              Can’t wait to see my GPU’s at work, love to test the GPU client for you and give feed back, PM me.

                Oh forgot to mention that I see a better hash rate with the CPU miner if I leave a core or 2 unused by the client.

                This was tested on my laptop Intel 2670QM, the 980x 6 core 12 th and the SR2 12 core 24 th all produced

                better k/hash per core if a core or two was left free. Not sure if that is something that needs addressed,

                but thought I’d mention it to get feed back from others and if there seeing the same thing?

                    For those that may not know you can use 2>> logPXC.txt at the end of the command line for the CPU client

                    and all client text will be placed in a Text file within the folder where the client is installed. Makes for easy finding

                    of blocks found “test on windows client” by using notepad to open the text file then under edit click on find, type in

                    yay and hit enter key, if you have found a block it will take you right to it, then you can use next to move forward and

                    see the next in line that was found.

                    minerd.exe --no-gbt -a neoscrypt -R 10 -o 192.168.1.107:9554 -O phoenixcoinpc:x --threads 20 2>> logPXC.txt
                    

                    Update on the EVGA SR2 Stock clock 2.13Ghz OC 3.33Ghz

                    Using 20 cores 51.66 khash.

                      Bump: Wake up! Everyone… ^-^

                      Set my i7 2670 QM back up today with the CPU miner working 6 of 8 threads.

                      12.31 khash/s (yay!!!) 1st of two blocks found start time: 15:27 found at 18:32 2nd block at 19:45 12.22 khash/s (yay!!!)

                      teaser: http://gyazo.com/de3e2c4b87eaa9c10c6cbeb1459795c3

                      :-* :)

                      RW-Everything and ThrottleStop are a must for this laptop to control fan speed and CPU multiplier to keep tempertures in check.

                      Asus G74Sx… Would love to see the Nvidia Geforce GTX 560m at work as well… This was while playing Total Domination online

                      so no problems doing normal every day use things while mining Phoenixcoin. Come get you some!

                            @daimyo: that ‘hash > target’ if comming from the pool

                            @Lizhi: avehre is working on the adaption of gpuminer to support pools. Currently cuminer supports stratum and longpoll on pools, gpuminer only supports longpoll

                              A new version of p2pool is available.

                              The problem should be fixed for GPUminer

                                Great work - cpuminer now workd great with stratum on p2pool.

                                I’m going to reset up the latest miners (cpuminer-neoscript, AMD cgminer, Cuda miner) a GPU PC -

                                Is there a guide to which is the latest downloads? with compile instructions.

                                I’ve got a couple of R9 270s I was going to reset up for the change over and a HD 6970’s I can test.

                                ++ Is there anything else to help with / test - before the update is released - e.g. Other types of pool? or exchanges?

                                    That depends what graphics cards do you have? It looks like the r9 280x gets around 100khs.

                                        Yes block 432.000 and yes that pool is listed and all ready to go once we hit that block.

                                        If you want to make sure you don’t miss the hardfork I’ve set up a twitter bot that is counting down the hardfork you can follow.

                                            Well not bad.

                                            I think you can reach ± 10kH/s with modern multicore CPU.
