This issue happens for me as well. I have Asrock H110 Pro BTC+ and from time to time, I lose internet connection and rig freezes. The moment I unplug ethernet cable from the rig, I recover internet on my main PC, but I have to manually reboot the rig.
I have followed also this tutorial, but nothing:
Let´s see how long it lasts now, this is just a pain in the a$$.
Still hapenning… zzzzzzzzzz
Same issue as a lot of you guys. Just total freeze ups happening sporadically with hard power reset the only cure.
Running gminer with 7x6800 XTs
Motherboard: Asus B450-F Gaming II
CPU: Ryzen 5 1600
Now. I have Two of these rigs. Identical cards, identical in all other ways in terms of the hardware. EXCEPT the memory, which is premium Corsair DIMM on the one that doesn’t freeze, and cheaper Vengeance LPX DIMM on the one that does. The memory is the ONLY difference between these two rigs. BIOS settings and version, overclocks on the cards, everything else is the same. So… seems to me at this point that swapping out the memory is the first thing I should try.
I also have an NVIDIA rig with the same base hardware, and that kept freezing up too, and it also had the Vengeance LPX memory, until I swapped out the memory DIMM, and since then it has been working flawlessly for weeks.
I’ve just swapped out the DIMM for the same type as is working in those other rigs and will post back here in a few days to let you know if that fixed it.
Ok good luck keep us posted 
Sorry to report I’ve already had my first freeze-up with the new memory. Sigh.
Hi again. It looks like I was able to fix the whatever issue I had. I just have now, from time to time, every few hours, miner reset, but that´s just a matter of seconds and it continues mining.
I originally had 10 GPUs (6 x Nvidia + 4 x AMD) and I splitted them in 2 rigs. 6 Nvidia one rig and 4 AMD the other rig, with another Vega56 I had there alone.
So far so good, no freezes, so I guess, somehow, H110 Pro Btc+ have issues managing so many GPUs or something like that, because having enough PSU power, 8 RAM, SSD, good overclocks… there´s no way it was a bad configuration issue.
So… yeah, I guess I will just stick to 5-6 GPU rigs Max.
Cheers!
well I spoke to soon , it wasn’t the monitor after all , i’m just about to try a different os, I really do like using hive os, my marriage is on the line here, I cbf listening to the mrs when this fails to be productive and she says " I told you so " I just can’t afford to have the 5 hour unnoticed outages, I haven’t been able to get a solid 24 hr run in 3 weeks
maybe it’s the combination of amd and nvidia, might have to keep them separate , Wow this is the perfect excuse i can use to convince the mrs that i need to build a second rig asap … lol
There was a post on redit, apparently it’s the am3 socket motherboards that suffer from this issue.
it just happens to be the board that i’m using.
Another post suggested that it was the mem overclock settings that cause it, a few people who were having this issue set their mem clock to default and they reported back with 7 day uptime after that , no real right or wrong answer , what might fix someone’s problem might not work for others.
I don’t think it’s the network driver in my case because the os locks up, I can’t type, I can only highlight lines with the mouse .
can you type when it happens?

what about these silicone gods I keep hearing about , I thought that you can’t compare 2 motherboards because they will always have some differences in the way they were made?
Nah it was totally frozen, but I solved it as I said previous post =)
I guess Nvidia + AMD is not a good idea for the H110 Pro BTC + at least. I will try though to put 13 total Gpus (All NVIDIA) and test if rig stays stable.
I’ve stopped my rig freezing and it’s been going for a solid 20 hours so far – previously it was freezing every 5-6 hours. I will post a shot of the BIOS settings I changed at the weekend provided no more freezing.
My setup is Asus B450-F Gaming II mobo, Ryzen 5 1600. Which is the same as a lot of other people in this thread with freezing issues. Hopefully I’ve solved it. We shall see.
Okay. Well into second day with no freezes, so here are the settings I changed if you have an Asus B450-F, Ryzen 5 1600. With other CPUs and mobos it will at least give you a direction to start looking.
The primary issue seems to be variable CPU clock speeds or ‘boost mode’. So the number one fix here is turning that off and assigning the CPU its native clock speed only. Which in the case of the Ryzen 5 1600 is 3.2Ghz.
Here are all the settings. Some may be unnecessary, but the combination of all of these is what fixed the freezing issue for me.
Hi, Im with same issue and read all threads and notice a lot people with Ryzen 5 1600 like my frozen rig, mobo A320M-S2H Gigabyte.
Next weak I`ll try to change the set Mob + CPU, maybe, who knows.
It does happen to me too, every 6 hours or sometimes 10 hours or sometime 12 hours, i am quite sure its not the risers or the configuration or overclocks. I have been reading here about the BIOS, perhaps the motherboard gets hot ? or the cpu become problematic ? first of all i will buy a smart plug to reset anytime. The biggest problem is it frezee the entire rig, mouse not working key board not working nothing working
The answer is literally two posts up, guys. 
I`ll try it!
i dont have a ryzen only a cheap intel celeron, so problem cant be that as i dont have an option for boost. i only have an option for CPu fan control which i put it up for performance mode. i will see if any thing on bios i can find the ones you have. my mother board is H110 pro asrock.
I LOVE YOUUUUUUU, not a freezer anymore!
Hello everyone…
I have the same issue but with an Intel Rig. Attached is my rig’s picture:
Motherboard: ROG STRIX Z490-E GAMING ASUSTeK COMPUTER INC. (2301 07/13/2021)
CPU: 20 × Intel® Core™ i9-10900K CPU @ 3.70GHz AES
Disk Model: Samsung Flash Drive FIT 64.2GB
I used to have 6 GPUs and was getting freezes 2-3 times a day. I moved one of them to a different rig and now with 5 GPUs I get 1 every day. I have replaced all the risers, done it with no OC, Low OC, different miners, USB, SSD, reflash of OS, used different NVIDIA drivers and no luck so far!
I don’t think it’s an AMD CPU issue… any help would be appreciated!
