I'm assuming you're running linux. Would there be a huge difference in PPD between Linux and windows? How many are you currently getting with your 1700? And I'm just assuming that the new Ryzen is going to be AM4 compatible? The first part was answered in the other thread, as I am sure you saw. The MCM currently take 3 hours 55 minutes on average. The MIP vary a lot, taking from 45 minutes to 2 hours 30 minutes. The average seems to be about 1 hour 29 minutes at the moment according to BoincTasks, though the most recent ones are less. Those are the only ones I am doing on the Ryzen machine, as they seem to be the highest priority. I have relegated the others to an i7-3770 PC. I am running Ubuntu 17.10 (Linux 4.13.0-17) on an AM4 motherboard (ASRock Fatal1ty X370 GAMING X). Memory compatibility has been a problem with some boards. I am using Patriot Viper Elite 32GB (2 x 16GB) DDR4 2666MHz memory with no problems. [Edit 1 times, last edit by Jim1348 at Dec 12, 2017 10:09:39 PM] |

Awesome, thanks!
----------------------------------------Hopefully this Ryzen works out. Looking forward to it.

Ha. I ordered a Dell XPS 8930 on Christmas and totally forgot about this thread. Here's hoping I don't run into similar issues -- I don't like noisy fans.
----------------------------------------I got the one with the 4 Core/4 Thread i3-8100 @ 3.6GHz so maybe it'll run cooler and use less electricity than the 6 Core/12 Thread i7-8700.

Ha. I ordered a Dell XPS 8930 on Christmas and totally forgot about this thread. Here's hoping I don't run into similar issues -- I don't like noisy fans. I got the one with the 4 Core/4 Thread i3-8100 @ 3.6GHz so maybe it'll run cooler and use less electricity than the 6 Core/12 Thread i7-8700. If it is noisy, it is likely the cpu fan and not the case fans. I have found with Dell, their airflow is less than desirable. The case fans stay at a low 20% or so rpms, and if the cpu heats up the cpu fan is what ends up spinning up to near full throttle to try to cool the cpu (all the while, the case fans stay at low rpms and never speed up to help out). A decent quality aftermarket cpu cooler will help push the air toward the rear case fan (if it will fit in the case and Dell hasn't made some type of proprietary mounting point for their mobos). And unfortunately, Dell uses some weird type of 5 pin fan connector for their case fans, not the standard 3 pin or 4 pin (last time I checked). That said, there are diagrams out there on the interwebs that show what wire goes to where, so you could turn a good quality pwm fan (I prefer noctua) to fit a dell case using the stock connector off the old fan.

Ha. I ordered a Dell XPS 8930 on Christmas and totally forgot about this thread. Here's hoping I don't run into similar issues -- I don't like noisy fans.

Not this time, it was both. I can tell you that there was a ton of air coming out of the top of the case where the case fan was. I don't remember specific RPM's though I did look and they were both right up there. Case fan was a bit lower, but not by much this time. The 8920 I tried out before the 8930 refresh didn't have any of these problems. The case fan, as you said, stayed right around 20%. And was a lot quieter. Tempted to blame Intel, at full load, that machine used just as much power as this AMD, and that's with the non k version. It ran in the high 80 c for temperatures, too. The 8920, i7-7700, ran at around 65 to 70 and had the exact same airflow design. It is literally like having a small vacuum in the room at full load. So much happier with the lenovo I picked up with a ryzen 7 1800x. It's been going fairly steady for the last few weeks, at least when it's idle. The tower is a lot bigger but I've heard mini towers that are whisper quiet compared to that xps either way.
