I can't see a reason why this system doesn't work stably. But if you have a restart problem, it may be useful to try your system with the stable system's PSU. Your PSU may be reaching the end of its life. You can set GPU power limit to -20% or -30% with WattMan for decreasing PSU load. You may need to also check your processor temperature. Graphics cards do not usually cause restarting problems. The components of your hardwares you choose have high quality. I hope you find out what the problem is.
I have this problem too. This is my PC build.
Window 10 64bit
AMD Ryzen 5 3600
ASUS ROG STRIX 5600XT 6GB
AM4 Ryzen ASUS TUF GAMING X570-PLUS
HYPERX FURY 16GB BUS 3200
POWER SUPPLY COOLER MASTER ATX MWE GOLD 650 WATTS
HDD 2 TB WD BLACK
SSD 250 GB WD Blue NVMe
But also your hardwares are very good. You shouldn't have a problem. I don't know the cause of the problem but I would like to share the following informations.
Your mobo wants to 8+4PIN CPU power supported PSU. This is not necessary but the mobo may want a good PSU than yours.
Because as you can see, your PSU only supports 8PIN CPU power.
Obviously I think your PSU has very good quality. You shouldn't have a problem. But if I had x570, I would have chosen a better PSU. Because the capacity of your PSU is very close to the system requirements. This can cause your PSU to become warmer. It may cause your hardware to overheat. Don't worry about the money you give to PSU. Because PSU choose is very important. If you cannot stabilize your system despite all attempts, make sure you use your consumer rights. If new hardware is troubling, it will lead to bigger problems in the future.
What brand is your rx 5600xt? All i know is the power limit of the card is only 10% max or am i missing something?ny
Reaching 1820mhz core clock actually easy for this card even with undervolting. But memory OC is different things, you can reach stable 1860mhz is already achievment. Have you try it with heavy game after OCing mem clock? I mean 3dmark alone is not enough for streest test nowadays because newer games are far heavier that a streest test in 3dmark.
A bit of a correction, what I meant to say is -30% my 5600xt is the Gigabyte Gaming with the tri fan design, I just played AC Odyssey for an hour and a half and no issues so far.
Man that is awesome. I'm using MSI RX 5600 XT MECH, not my first choice so i kinda dissapointed.
I can reach 1820Mhz core clock easily by downvolting to 915. But the mem clock is different things. I can only hit 1620Mhz max which is suck.. But glad that core clock has a bigger impact for gaming than memory clock.
I'm in the same Bug Check boat with my RX 5600 XT's except I'm using them for mining using the Claymore miner. I have the system set up with the 2-5600's and three GTX 1600 cards. The system is using the Intel GPU built into the G4400 CPU for display. I never seen or heard of the Bug Check error until I made the "mistake" of trying the AMD cards. I have two other miners running NVIDA cards using the built in Intel GPU and they have been running for years without an issue. These two miners share a screen and mouse via a two way TVSmart KVM Switch.
Anyway, I was experiencing a Bug Check once every two weeks or so on the system with the 5600's. Then I got cute and tried to use a second two way TVSmart Switch connected to the miner with the 5600's and my Home Server. Once I connected the Miner with the 5600's to the Switch I got the Bug Check error ever few minutes! It did seem to extend the time between Bug Checks by a few minutes if the Miner was not selected on the switch but that may have been fluke. So whatever the driver problem the KVM Switch brings it out immediately and often!
The RX 5600 XT's are great miners but the driver flaw is a giant pain. Please, please fix the #$%^ isuue. I want to buy more of these cards for mining but I not until they work correctly.
