Posted 26 Feb 2023 by hoppisaur Post: It is. *ahem* will be. The only, quasi-stable, config I have been able to do for linux for firepros (and Bristol Ridge R7): Ubuntu 20.04 (either .1 or .2 (I think). Install and pull the internet during installation as even if you say don't upgrade: it will helpfully update you to kernel 5.15.XX which I haven't been able to get amdgpu to work on. period. Uninstall snap. Disable unattended upgrades. Turn off crash reporting. Never allow upgrading to go above kernel 5.4.0.XXX otherwise amdgpu 20.50 will break, at least in my experience. I use amdgpu v20.50. Nothing else works. I only install --opencl=legacy. I don't bother with vega or later if the firepro is on the system. Since I have dedicated crunchers, I will ssh into them as amdgpu tends to make video broken, but the firepro is seen and works. boinctui makes life bearable via cmdline. Hope this helps. |

Problem with ntoskrnl errors with AMD A8-7800 APU
(Message 70389)
Posted 18 Jan 2021 by hoppisaur Post: You can also create a separate "location" in Milkyway@home preferences under your account. For that separate location (work, school, doesn't matter) you would assign the problem machine to that location. You can specify only CPU tasks and not have it affect the rest of your computers. |

GPU tasks error out on Linux
(Message 70306)
Posted 4 Jan 2021 by hoppisaur Post: I did not have many errors on my RX 570 until I upgraded to Ubuntu 20.04.1, which requires the latest (20.45) drivers. Don't know if this helps: I have been able to use amdgpu 20.20 or 20.30 with Ubuntu 20.04.1 Had a problem with getting a stable desktop and found that the trick is that 5.4.0-56 or -58 breaks the amdgpu drivers. See here: https://community.amd.com/t5/drivers-software/can-t-install-amdgpu-drivers-on-ubuntu-20-04-1-5-4-0-56-generic/td-p/426676. Once I uninstalled kernels greater than 54 and reinstalled the amd drivers, it has been stable. If your computer is your daily driver, you will have to come up with a strategy to prevent Ubuntu from nagging you to death to upgrade. |

Benchmark thread 1-2019 on - GPU & CPU times wanted for new WUs, old & new hardware!
(Message 68953)
Posted 5 Aug 2019 by hoppisaur Post: A12-9800 #1 on Ubuntu 18.04 using amdgpu-pro 18.50 opencl=legacy 227.xx = 96.3 seconds from last 13 valids A12-9800 #2 (latest purchase already killed a motherboard after 3 days!) on Ubuntu 16.04.6 using amdgpu-pro 17.50 opencl=legacy 227.xx = 96.6 seconds for last 20 valids Both motherboards are set to C6 = disabled, Core performance boost = disabled, Cool'nQuiet = enabled. Both mobos have 2 x 4gb DDR4 2400. Both BOINC clients are set to using 50% of CPUs. Watching clockspeeds in terminal, clock speed will sit at 1396 across all "cores" and jump up to the 2-3 GHz range briefly when it is offloading from the GPU. Difficult to tell peak clockspeed as time resolution of terminal window is not that fine. |

New Benchmark Thread - times wanted for any hardware, CPU or GPU, old or new!
(Message 68098)
Posted 6 Feb 2019 by hoppisaur Post:
Sorry for late response. Normal freq of chip is 3.8 with capability to boost to 4.2. Main change I made in was to disable C6 as it was freezing when left alone for a while. If I watch clockspeeds via lscpu, the most it boosts is ~4.0 so call it whatever. AMD CnQ is on because that allows it to drop frequency on the cpu cores to give power to the graphics cores. It is on a A320 chipset mobo so iGPU is not possible to OC. The 227s have been in the 100-101 range and the 243s are in the 107-108 range. My computer is visible so verification is available to anyone who wants to see. |

Posted 15 Jan 2019 by hoppisaur Post: Of latest 14 validated 227.62 WUs, avg is 100.65 secs. Chip is at 3.8GHz. I've tweaked BIOS on another board as much as I can. First board died complete with magic smoke. A12-9800 with dual channel DDR4-2400.

Posted 23 Dec 2018 by hoppisaur Post: It is trending slower today as I turned off motherboard core boost (3.8 -> 4.2) to see if I am hitting a wall with what the motherboard is able to deliver. 10WU avg is now 135.06. I think my powersupply isn't up to the task of boosting the cpu while the iGPU units are being used. Or it could just be driver or mobo related. I am going to try other hardware as it was frozen this morning (locked up). Yes, agreed, I think the proximity of the gpu and cpu units is advantageous in an otherwise mediocre chip. Or maybe they share the cache? Avg (of 5) = 120.33 seconds from the 227.62 WUs |

Posted 23 Dec 2018 by hoppisaur Post: Avg (of 5) = 120.33 seconds from the 227.62 WUs AMD A12-9800 stock; ddr4-2400, onboard (iGPU) R7 graphics Boinc 7.9.3, Ubuntu 18.04.1 LTS, OpenCL 1.2, amdgpu-pro 18.50 drivers. Only MW@Home running. No CPU tasks. 1 WU at a time. Still not 100% stable. Will investigate if power delivery issue or driver issue. Locks up when asked to do too much. Stable if left to crunch.
