similar problem with q6600 + 5970, W7 x64, ati 2.3.451 each instance of poclb using one core to the full  no such problem with single 5870 - it uses 3-5% of cpu |

HD5770 + Ati Stream 2.1 + Catalyst + Windows 7 64bit = worked out of teh box without any issue. Well, actually i have an issue: 25% constant cpu load (quad core machine). I only have one miner instance open, crunching at +- 170Mhash/s with the gpu. How come it is using that CPU core? [edit] @m0m Hey man, could you please update the executable on OP? I'm lazy to setup a compiling environment  [/edit] do Ctrl alt delete and check your processes to see what is using your CPU poclbm.exe is using 25% cpu, tot it was obvious  Not explorer.exe or something else. |

poclbm: each miner appears to use exactly 25% of your CPU. Open task manager and start/stop a miner.

Each miner is using 1/N_Core of your CPU, where n_Core is the number of Cores detected by windows. If you have HyperThreading, enable it to half the CPU usage. |

It shouldn't use any CPU (unless you use it on your CPU which you should not). Any other CPU usage is cleanly problem of driver + OpenCL SDK + OS.

Hi m0mchil I do experience 25% load on the cpu per poclbm instance. I have tried running with 10.11 + 2.1 stream but poclbm refused to load. Also 11.2 + 2.1 doesnt work either saying that no opencl device detected. 11.2 + 2.2 on the other hand runs with the 25% load issue. I am running win 7 64 bit. Any advice on the configuration?

This won't half the cpu usage, just apparently. It half the cpu time, as well as Watt and cpu usage %. Another "solution" is to stack all the process in 1 core, changing the Cpu Affinity under the system monitor (CTRL+ALT+CANC). |

It half the cpu time, as well as Watt and cpu usage %. No, it just looks that way because Windows will say that 100% of one core on a dual core CPU is 25% instead of 50%. You still only have two cores, and a single process will 100% of it even if you enable HT. Enabling HT will not give you twice as many cores or twice as high performance. If two process use the same core with HT, it will only be a few percent more efficient than using a single core at best. Setting affinity is much better. |

Too bad my Watt meter do not agree with you. |

Windows has probably put two process on the same core, then.

win 7 64 with 2 6970's and I'm getting 50% usage. 25% for each gpu instance. Was on 2.3 11.2 and was having this prob. Now on 11.4 and 2.4 and still having the same usage prob. Doesn't fix anything.

When I download it on Windows 7 it says "What should Firefox do with this file?" then you can tick a "Open with" box that has a "Browse..." button after it, or a "Save File" box. I tried both but I didn't know what program to open it with. Also, I followed the first three steps of these instructions. Only the first three because the rest was for after downloading the miner. |

It's a 7zip file. Open it with any good archiver like 7zip/WinRAR/etc....
