@FrankMB Thanks for sharing your results, and thanks to everyone who contributed to this post. I have been busy with work lately and wasn't able to post. I was wrong about this being a software issue. The fact by changing the MB alone fixes the problem seems to confirm one of my more recent suspicio...

@muziqaz Thanks for sharing your data. I'm going to wait until Zen4 comes out and upgrade my system then. If it is a hardware issue, hopefully it will be gone in the new arch. Meanwhile, I'm contributing to other Boinc projects like Rosetta Stone and GPU Grid, without problems. F@H will have to wait...

@muziqaz Actually, this problem had started some time ago on my previous system, based on the AMD 1950x, on an Asus board. It showed the same symptoms, and that's why I upgraded my system. No other software causes this problem, so I doubt this is hardware. I ran AVX benchmarks on Linux and had no pr...

Thanks for sharing your data, @ElephantFly. It appears FAH code really has problems with the 5950x. I hope developers are paying attention.

@mitalapo

Yes, that has been my experience as well. I hope we can find what the problem is. Thanks for sharing your data.

@mitalapo
Sorry to hear that. I also tried running the Linux Prime95 AVX stress tests, but that did not generate any problems, even after several hours. The mystery continues.

@mitalapo

Thanks for the info, will try those settings.

Hi @mitalapo,

Thanks for the info. It seems there might be an issue when running F@H with 5950X's in Gigabyte MB's, you are the third person to report a similar problem in this post. I don't get any MCE's, the system just reboots silently, and only when running F@H.

@FrankMB

I ran Linpack Extreme in Linux at max settings for about 74 hours. Not a hiccup. This machine is very stable. The only software that causes the silent reset issue is still F@H. Not sure what else I can try.

Thanks,
Marius.

@FrankMB

I have been running Linpack Extreme, in Linux, at max settings for 24 hours now, and there were no problems so far. I'm tempted to leave it running for the weekend, just in case. I will update this post then.

@FrankMB
Thanks for letting me know. I will setup Linpack and report back later.

@FrankMB

I haven't tried Linpack yet, but the symptoms you describe are similar to what I get with F@H. My motherboard is a Gigabyte X570S Aorus Master, what is yours?

@FrankMB I tried all that too, without success. For now, I am running Boinc with GPUGrid, Rosetta Stone and Milkyway projects. Of those, the GPUGrid project puts the heaviest load on the GPU, and it's pretty similar to the power consumption I've seen in F@H. I have been running it for several months...

@MeeLee, @ToTow It's not a power supply issue. I had an EVGA Supernova 1600 P2, and I upgraded it to the most powerful PSU I could find, the Corsair AX1600i. No difference. It's not a CPU issue. I had an AMD Threadripper 1950X and replaced it with a 5950X. No go. Let me say this again, the silent re...

@FrankMB Yes, my experience has been very similar. The silent reboot happens only in F@H. Nothing else I tried causes it. The silent reboot happens if I fold with only the GPU, only the CPU or CPU+GPU. It also behaves the same regardless if I fold in Windows or Linux. As have you, I upgraded every c...
