        Don’t know why, maybe its a Chrome thing.

        I use Firefox and just opened up IE and it works for that too.

        Ijust realised I left a space in the filename, maybe Chrome doesn’t like that, so I have fixed it.

        I’ve updated the link above, but here it is again

            I am so ready for the 25th. You guys should really edit the first post of this topic so people can find the right download on the first page.

            says zlib1.dll is missing

            The cgminer 1.75 zip file from the first page don’t have that driver. You don’t want that version anyways. 1.7.7b is more stable and has higher performance.

            Also a link to version 3.7.7b that i compiled with these instructions

            https://mega.co.nz/#!FcVTEQyQ!ozPVAzZJCIGm7-nbqB3E4y1xudHI62g6YVfF_YI_GUI

            I am running that version with my bat file:

            setx DISPLAY 0

            setx GPU_MAX_ALLOC_PERCENT 100

            setx GPU_USE_SYNC_OBJECTS 1

            cgminer.exe --neoscrypt -I 11 -w32 -g 2 -o stratum+tcp://atlas.phoenixcoin.org:10554 -u

            -p x

            I am getting 40.5khash/sec on a GeForce GTX 560.

              The current version of neo-gpu miner does not work with AMD drivers higher than 13.12.

              I found that when i add the amd opencl files from the 13.12 driver pack to the cgminer directory that it does work with the 14.xx drivers.

              But a little slower…

              If anybody is interested … link to neo-gpuminer 3.7.7b that works on 14.xx AMD drivers

              https://mega.co.nz/#!lVUURaAK!epWoeHGYXiKFXlAJ2VvG9LwuUBh-4bi1TNS-JXjgxLQ

              Using setx display, gpu, etc does not add anything to performance, just leave it out.

              I get 90kh/s on an amd 280x with these settings

              cgminer.exe --neoscrypt -I 14 -w 48 -o stratum+tcp://prometheus.phoenixcoin.org:10554 -u

              -p x

                280x hynix= 100khs

                have u tried bin files crossed? freshalgo did best when 14.xx created bin at 13.x drivers

                        folks can we do a quick wrap up of what we have had so far?

                        this is a track record of my progress with the gpu miner

                          hi guys

                          i just hooked up a amd 6950 and i downloaded the cgminer, but when i run it, it just stops working and crashes. I’m using windows 8 64bit. and just updated my drivers to the latest. Could you know why this may be happening?

                            If you are using catalyst 14.something it won’t work.

                            Don’t go higher than 13.12

                            But there may also be win8 issues as I know of atleast one other person running win 8 that is having issues

                              my 6950 is really slow… its like just 4kH

                              @Yusuf, you may want to try a higher -w value…

                                aah tmuir12, thanks. i think i was using the 14.xx catalyst from above. could you please link me to the pre compiled cgminer for 13.12?

                                thanks again!

                                  I have two PCs with Radeon HD6950s, shaders unlocked. They’re not cutting edge, but they are decent miners. Slightly overclocked, they get about 450 KHS scrypt mining each, or about 7.5 MHS each mining Goestl.

                                  The PCs are running Windows 7 X64. One has 13.12 drivers, one has 14.4. That really doesn’t seem to matter, at least on my two PCs. Swapping bin files had no impact.

                                  I have tried the Neoscrypt GPU miner, versions 3.7.5 and 3.7.7b. I get accepted shares, and I can solo mine, but the mining is at very low hash rates.

                                  After reading through this whole thread more than twice in case I missed something, I have tried a variety of different settings. The best I can get with HD6950s is about 3 KHS, and it renders the PC unusable, even at relatively low -I settings (-I 8. I get similar performance (~2 KHS) per core CPU mining, and the PC is pretty usable while minerd is running. So at the moment, CPU mining is about 4 times more productive and uses about 1/3 of the power as GPU mining on my hardware. But CPU mining is never going to be productive when most other miners are using GPUs at 25-50 KHS.

                                  This is going to alienate me from Neoscrypt if this is not addressed. Since this beta has been release, difficulty has gone up, and that’s only going to get worse when there is widespread adoption of the GPU miner. I’m not going to buy new GPUs just to mine PXC, or FTC for that matter.

                                  I’m not whining, it’s just a simple decision based on the relative performance of my hardware. Some of the comments here have been “when are we going live?” If this doesn’t get fixed, I’m not going to be able to reasonably compete any more, and I’ll have to find something else to mine where my hardware is competitive (like Groestl), and so will anyone else mining with similar hardware.

                                  I don’t particularly want to abandon PXC, I’d much rather stay. If I can help the developers to resolve the performance issue by testing or providing log files or whatever, I’d be happy to, just let me know what I can do.

                                    use only 3.7.7b miner for now

                                    your settings are way off to get good hashrate. -I 8 is history now.

                                    try -g 2 -w 24 -I 14 , if failing take some steps down, i have not a card similiar to yours, but your setting should be much like mine

                                    when mining scrypt cards like yours been reported using intensivity 20+

                                      I think AMD HD6XXX may be supported. my 6770 and 6870 only 2.5K/hash. If I use lasted 3.7.7b, It is 4K/hash ,but I think they should 20K/s hashrate.

                                        You can’t set the same -w value for HD6XXX as for HD7XXX and R2XX anything lower than 64/128 and it will fail to start.

                                          My settings are way off? I’ve tried alot of settings. How do you know what settings I’ve tried? I only mentioned that it renders the PC unusable even at relatively low intensity settings like -I 8, while CPU mining 4 times as fast is only minimally noticeable, I can leave minerd running all day long, and use the computer for everything except gaming or using flash while mining…

                                          I’m a newbie here. I’m not a newbie to mining. I have tried more than reasonable troubleshooting.

                                          I’ve been trying this for about 3 weeks, since 3.7.5 was just released. I’ve tried numerous settings. I’ve tried both 13.12 drivers and 14.4 drivers. I’ve tried installing the sdk to see if that helped. I’ve tried making the bin on 13.12 drivers and using it with identical parameters using 14.4. I’ve tried alot of things.

                                          I’m open minded, and I want this to work. so I just tried your settings, -g 2 -w 24 -I 14. My GPU won’t start at those settings. -w 24 is the problem. it causes:

                                          Error -54: Enqueueing kernel onto command queue. (clEnqueueNDRandKernel)

                                          GPU 0 failure, disabling!

                                          GPU 0 failure, disabling!

                                          Thread 1 failure, exiting

                                          Thread 0 failure, exiting

                                          If I make the settings -g 2 -w 32 -I 14, it starts succesfully and mines at 3.8 KHS, a new record for me, but still less effective than CPU mining, and it renders the PC unusable. With these settings, driver does appear to make a difference. The 14.4 driver only gets 2.4 KHS and is noticeably more laggy, like borderline unstable even.

                                          -g 2 -w 64 -I 14 yields 4.188 KHS. Better. Finally have performance equal to a core 2 duo CPU mining. Probably using twice the power to do it. Laggy as hell, even on the 13.12 drivers. cgminer became unresponsive after a while. I think it was still mining, but cgminer stopped updating the screen, and I couldn’t even quit, had to hit the red x to get it to stop. Still nowhere near a 6 core amd CPU for productivity or efficiency.

                                          -g 2 -w 64 -I 12 yields 3.23 KHS, seems stable, but pointless.

                                          -g 2 -w 128 -I 12 yields 3.0 KHS, not helpful.

                                          -g 2 -w 128 -I 14 yields 4.0 KHS, then the graphics driver (13.12) blew up.

                                          I’ll try anything you gentlemen suggest, but if I can’t get at least 15 KHS when newer cards are hitting close to 50, this is pointless. There is something wrong with the with how this miner/kernel interact with older radeons. Hopefully, it can be fixed. if not, I understand, and I’ll move on.

                                          Edit - I 14 appears to produce less accepted shares. Hashrate measured at the pool is higher with -I 12.

                                            You download it from the AMD website, you need to hunt a bit on the page, but you can download previous versions from their website, they are big downloads though

                                            http://support.amd.com/en-us/download

                                            after selecting your graphics card details and operating system it will bring up the latest driver, look to the right of the page under ‘helpful links’ for ‘previous drivers and software’
