I have mined in the past with no issue. I have updated the wallet and miner. Just tried to mine on nonce-pool and get all rejects. Any ideas?
Anybody else having problems with the pool? Pool is fixed now, to algo v2, somehow we missed a name change. Just tried again and now cannot connect. Currently only stratum port 3390 is open for mining. |

The point is changing the connection port to
-o stratum+tcp://mine4.khc.nonce-pool.com:3390
Cheers
btw: anyone mining with an ASUS r9 290 ? (or 290x) how much do you get?

I'm getting 330Kh/s on my 290x

What does your config look like? I do not see even close to that. |

What does your config look like? I do not see even close to that. With AMD HD 7xxx and later GPUs, running the latest Omega drivers, you have to use an option called --cl-opt-disable. For some reason these latest AMD GPUs with GCN architecture work better when you disable OpenCL optimizations. On the other hand, this option doesn't have a positive effect on older AMD GPUs and nVidia. Example for my 290x: cgminer --kryptohash --cl-opt-disable -o http://127.0.0.1:38912 -u {RPC_username} -p {RPC_password} --shaders 2816 --shaders-mul 8 Very important: Don't forget to delete the kshake320v2%YourGPUname%.bin file inside the cgminer directory after you add/remove the --cl-opt-disable parameter. It is the only way to force cgminer to recompile the OpenCL kernel and include/remove the cl-optimization flag. |

Yes, be careful with the temperature. If it is getting too hot, try reducing the Intensity from 32 to 28 or 24 |

are there people here who undervolt/overclock their cards ?
if so what settings do you use ?
Is there any advantage to lower the clock ?
I have a sapphire 280x that runs 200 kh/s with these settings ...
@echo off
del *.bin
timeout /t 6
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --kryptohash --cl-opt-disable -I 28 --gpu-fan 100 --shaders-mul 8 --shaders 2048 -o stratum+tcp://mine4.khc.nonce-pool.com:3390 -u xxxx -p xxxxx
running @stock clock 1020/1500 vddc 1175
temp 73c

This could be the most power hungry algorithm to date. That has to be worth something.  |

Thank wr104 you for the hint about deleting the .bin file! I now successfully disabled opencl optimization and my ASUS r9 290 bumped from 150Khps to the current 291Khps @ about 90C°/ 2200 RPM. I suppose I should "tweak down" the thing a little bit...
Oh, but did I dream or the walled briefly said it wanted an update? I'm running v0.5.0.0-g0-beta (64-bit) . I went out to check a newer version and now the message has disappeared. MD5 of my install file is 87b1557e2d4cbf8c95616b48c34ff537 (as well as the latest I could find linked in the homepage)
Ok maybe it's my brain that can't sustain all that heat! :-D

The net hashrate is lower than 4MH/s ,very dangerous!
As long as the Diff remains above 32, we are okay. Besides, this means you and me will be able to mine more coins before the big announcement.  wow,when will the big announcement be announced ? I'll point some of my rigs to nonce-pool. |

It would be nice to have p2pool software for this coin.

I'm now seeing this issue where the Wallet 0.5.0 warns you about having an obsolete version. I'm debugging it now. Edit: The warning can be safely ignored. I'll build a new Wallet 0.5.1 to fix this issue and also add a checkpoint for block 50,000 to seal the network transition to algo version 2. |

navybluevip. I will pay you 1000 KHC to fix your miner on nonce-pool. Just fix it and pm me your address.

E9800 you have quite a huge hashrate! How do you get such a high value? I'm asking just out of curiosity ;-)

2 290X 3 290 5 280X 9 270X 2 270 2 265 6 750 TIs I'm afraid to see my power bill after this but I believe right now with low hashrate is the time to mine KHC. Miner seems to be fully optimized for AMD unlike many other algos. |
