fuzzydice55,
Right off I don't think there is a server version of mint. It doesn't matter to me I am not accomplished enough use a headless version. How did you get your power consumption down so low, especially running a video card? |

BOINC only controls the work and sits idle most of the time. Your photos show stats from work units which is not BOINC. Why would one want to spend any time trying to optimize a program that basically does nothing except download/upload files and prioritizes the science apps? I believe all your comments are directed at the science apps and not BOINC. |

fuzzydice55, Right off I don't think there is a server version of mint. It doesn't matter to me I am not accomplished enough use a headless version. How did you get your power consumption down so low, especially running a video card? My config: MSI Tomahawk B350 mobo Ryzen 1700 @ stock speed 2x8GB 2133mhz memory Asus strix GTX 1060 1x Samsung 951 SSD 1x 4TB WD blue HDD 3 case fans 80+ gold PSU Some possible causes for the W difference: - The GTX 1060 is very efficient when idle, only 9W. It's possible your 5450 doesn't go to idle which would add 10W to your rig. - The HDD is turned off after 20 minutes, crunching is done on the ssd. This saves 7-8W compared to running from HDD. - Core voltage on the CPU: different motherboard manufacturers/types give different core voltage for the same CPU. I had a 4790k which was running at 1.2V on an ASRock board running at over 1.3V on a Gigabyte one. Voltage difference in power consumption is quadratic, so even a 0.1V increase will net you a large difference in power consumption. My 1700 runs at 1.112V on 100% load. - I have a 80+ gold PSU (88-92% efficiency). If you use an older/cheap PSU, efficiency can be even lower than 60%.

I replied earlier, but guess it got caught up in the switch over. My config: Gigabyte AB350M-Gaming 3 R7 1700 stock speed @ 1.09v 2 x 8gb running 2133mhz "brand?" hd5570 1 x BPX M.2 240gb 1 x case fan 120mm 80+ Silverstone ps You may be able to cut your cpu voltage back even further, since mine is running less than yours. I thought the video card was a 5540 but after looking closer at it I found out differently. The power supply is 80+ but don't think it is much over 80. What wattage is your ps? I wonder if I used a lower wattage ps if that would bring down consumption?(less overhead) Would the efficiency of your ps(88-92% efficiency) and mine (80-82% efficiency) make the difference consumption between our rigs? I bought this ps a couple years ago for an intel project that has been replaced by this r7. [Edit 1 times, last edit by dondee at May 17, 2017 4:13:27 PM] |

@dondee - the psu is likely the culprit. I have read articles that have tested power supplies, and the ratings actually make quite a bit of difference. From what I understand, a lot of power is lost as heat, and the more efficient the psu (better ratings), the less power is lost. Also, if you have for example a 500w 80+psu running at 50% load, it will be less efficient than fuzzydice running a 500w 80+gold psu at 50% load. From what I understand, the sweet spot of efficiency on a power supply is around the 50% load range, especially when you get up into the gold/platinum/titanium ratings.

the Ryzen multi-core is a new and exciting product,
So take care to read the guides in the lower half of the document, AVX2, RDSEED, ADX and additional encryption formats are some of the most exciting changes to the AMD Ryzen Arch. http://32ipi028l5q82yhj72224m8j.wpengine.netd...imizing-For-AMD-Ryzen.pdf - code optimisation a few very important lessons... may seem simple to some but obviously is not to be taken for granted. |

Compared to the 5450, the 5570 uses 3+ watts when idle, 50+ watts under load.
----------------------------------------There's a chance that the 1060 is much more efficient on idle. When I changed from a 80+ bronze to a 80+ gold PSU, it didn't matter much, a few watts at best. Current: Thermaltake Paris 650W Old PSU: Thermaltake Berlin 630W (these aren't regarded as very good PSUs, so don't go buying one  )If your PSU is 80+ bronze, that means at 20% load it's 80% efficient. If you're under 20% load, your efficiency could be much worse, since 80+ bronze isn't certified under 20% load. http://orig01.deviantart.net/fef6/f/2010/103/...ency6_by_phaedrus2401.jpg PSUs are usually most efficient at 50% load. You aren't likely to get a 80+ efficient 240W PSU for your rig, so getting that 50% load might be tricky As long as you're over 20% load you should be good.

I believe all your comments are directed at the science apps and not BOINC. umm yes at the project and the users but while the oportunity comes to optimise the boinc program itself in addition to the project's, the worth of doing both at the same time is sensible :-) and in addition .. since the capacities of the Ryzen include RNG Seed and ADX there is a lot of merrit involved in optimizing the boinc projects to the "CREDIT" of the programmers and science folk |
