I'm not sure what kind of links (which sites?) to post.
----------------------------------------Where are you from? I'm from Germany.  [Edit 1 times, last edit by RoundFour at Nov 13, 2017 9:35:49 PM] |

Haha, ok, what about this:
----------------------------------------AMD Ryzen 7 1700 (286 €) ASRock A320M-DGS (47 €) Samsung DIMM 8GB, DDR4-2400 (72 €) Xilence Performance C Series 300W (25 €) => Yes, this is pretty cheap, but in tests it proved to be really efficient with a low power consumption. So that's 430 € (without case) for around 66 Gflops and maybe 70-80k PPD or more on WCG. Notes: The A320 chipset does not support overclocking and only supports CPUs up to 65w TDP. To save power you should still be able to lower the CPU voltage through ASUS AI suite. If you want to have more settings you need something like the MSI B350M PRO-VD Plus (64 €). Also 4 GB RAM should be enough for WCG if you want to save even more (although a 8 GB module is cheaper per GB). My E3-1245 ran with 4 GB for 3 years and didn't have any problems.

If you can afford a 80+ power supply, it will be more efficient. I purchased an 80+ gold psu for fairly cheap here in the US, and it is rated at 90% efficiency. DDR4 prices are ridiculous high right now, so go with what you need for now and when it finally settles and goes down to normal pricing, you can always add more later.
----------------------------------------My 1700 (non x) system usually gets me right in the range you estimated, 70-80k per day, give or take. Sometimes a little higher, than 80k, sometimes just at 70-71k. I guess its just a matter of when it does the reporting of completed work. Edit: I also got a B350 board. They can be had here in the US for not much more than the chipset you suggested, and have a lot more features. [Edit 1 times, last edit by Former Member at Nov 15, 2017 12:49:57 PM] |

Nice, so my Gflops to WCG PPD formula seems to be correct ;-)
----------------------------------------I really want to build a crazy Xeon rig, but depending on which Xeons I'd take, I can just buy 2 or 3 Ryzen 1700 systems and it will always be more efficient... |

Oh the 1700s are definitely nice chips. I can't remember what temps I was getting at full 100%, but it wasn't anywhere near the comfort limit. I didn't use the wraith cooler it comes with though, I bought an aftermarket heatsink/fan combo from noctua. This is the one I bought https://www.amazon.com/gp/product/B01N9X2YYN/...o01_s00?ie=UTF8&psc=1 keeps the cpu nice and cool. I added a second fan in push/pull design, but it's really not needed. I just added it in case one fan ever goes and I don't notice, the other will keep it cool.

Yeah, the Noctua coolers are pretty good!
----------------------------------------Do you know how much power it draws under full load? |

Yeah, the Noctua coolers are pretty good! Do you know how much power it draws under full load? The full system from the PSU, or the CPU itself? If CPU only, I'll have to find a way to see how much it is drawing. For the whole system, I have a kill-a-watt PSU meter I can attach and see how much is being drawn from the wall if you like. |

Full system would be interesting.
----------------------------------------But comparability is of course very difficult. Maybe you could attach the meter and also list the other components you got in there. Thanks :-) |
