Ryzen 5600x build freezes in Windows 10 after it was initially very stable under high load

Been collecting parts from various RFD sales, but having problems with it:
  • CPU: AMD Ryzen 5600x
  • M/B: Gigabyte B450 AORUS M (Flashed to latest BIOS F63a)
  • RAM: 2 x 8GB DDR4-2666 Team Group (SK Hynix) - TEAMGROUP-UD4-2666
    2 x 4GB DDR4-2133 Kingston (SK Hynix) - HKX2133C14D4/4G
  • GPU: AMD RX480 8GB
  • SSD: Kingston A2000 1TB M.2 NVMe
  • P/S: EVGA 500W 100-W1-0500-KR
This build has been extremely unstable.

Initially, I put Unraid on it with a GTX 1050 Ti for encoding, and that seemed to be stable, but I had to give up on it due to Unraid's issues, apparently an incompatiblity with Ryzen motherboard SATA controllers causes the disks to be unrecognized even though the data on it was fine, and the USB port disconnects sometimes causing Unraid to think my USB-key is unlicensed.

Then I put Windows 10 on it with the AMD RX480 for gaming, planning to use it as my gaming/desktop PC insteead. On first boot-up it seems to work fine, and I was able to encode some videos on it for 3-4 hours with 100% full CPU load, no problem.

Then I rebooted, and it has been massively unstable. It would go to blue screen with IRQL_ errors or MEMORY MANAGEMENT errors within a few minutes of logging in, making the system unusable.

I started playing with some BIOS settings, like turning off C-states, downclocking the RAM, turning off the fTPM module, and even totally clearing the CMOS via jumper. Now instead of blue screens, I get a hard system freeze (ie mouse just stops moving).

I have also wiped the SSD and put a fresh copy of Windows 10 on it, but still the same freezing problem.

The weird thing is that the system had good stability under Unraid and on the first boot-up under Windows.

Aside from the CPU and mobo, the rest of the hardware has been tested and runs fine on my (older) Intel systems.

I'm not really sure what the problem might be. The memory is definitely not optimal for this CPU+M/B, but I don't think it should cause bluescreens/freezes, maybe decreased performance.

Eventually, I want this to become my Unraid server/VM host, but before I spend another $150 for faster RAM, I want to be sure that it will fix the problem.

My first guess is your RAM. Maybe just use the Team Group RAM and see if it freezes?

I neglected to mention that I did try different combinations of RAM sticks (always in matched pairs by manufacturer though) in various slots. The problem still occurred.

As an aside, that's when I learned that DDR4 sticks don't have a straight bottom edge, and that's by design.

Did you check the event logs in Windows ?

I had problems with my Aorus B450M too. Does it hold it's XMP profile after a cold boot? ( as in pulling the plug from power supply and switching the power supply off and wait a minute or so). and does it experience long initial boot time? For my case. it appeared to be a BIOS issue that it was defaulting to the backup bios (hence the long boot). What solved that problem for me was I first updated both primary and backup bios to a version lower than F63a (there's an option when you update bios to update both), then updating the primary bios only to F63a. This was with a Ryzen 2200G. I subsequently put my 5600G in the aorus board now and it's working fine.

I also recently had another Ryzen issue on a different motherboard that's more similar to yours that the computer will randomly bluescreen, NOT on initial boot after windows installation or safemode, but after device manager finds and installs all the drivers. I couldnt narrow down after which driver that will cause the freeze. Sometimes it'll be good for a few minutes that I can complete a Cinebench run, but then it'll suddenly freeze and bluescreen. A telltale sign was the keyboard is locked out of the search bar on the bottom and then mouse will freeze then blue screen. It turned out to be power supply problem for me. This was on a MSI b550m pro-vdh wifi. The board did not like my Corsair 550W, Nor did it like my Seasonic 620W, it'll only work normally with an EVGA 750W BQ 80+ Bronze that I had on hand. I don't know how the PSU caused this issue, but changing it around worked for me. This was with my 5600G so there were no other big power draws. Hopefully this tip will help.

So many suspect parts and configurations.

Gigabyte's B350 and B450 boards' have known issues with 4 sticks of DDR4 at higher speeds(and in general) if you don't apply the EC-Firmware update after ~F31 BIOS series.
Did you do this? And some other weird stuff with the PCI-E lanes. Their BIOSes are buggy as hell. They've had issues with fTPM and AMD also has bugs in the new AGESA with fTPM doing weird stuff.

The 500W power supply isn't the best but should power the 5600x and 1050Ti No problem, however might give you issues with the RX480 and 5600X if you have PBO on and a whole bunch of platter drives. I had the 430W version powering a 3600 and 1050TI before I upgraded.

The mismatch RAM combo will be an issue if the Board isn't applying JEDEC speeds correctly forget XMP at this point.

This is what I would do at this point.
Go to a bare configuration. Disconnect your extra Platter drives (I'm assuming you have them since you talked about UNRAID and serving).
Manually set the memory configs to a JEDEC Speed and timing that both sets should support. Or Yank tjhe 8GB kit and Just run the team Group and see if it works.
Reset BIOS. Load optimized defaults and start from there.
C-States and etc are pretty stable default from the last AGESA.
Use DDU to clear all your chipset and video drivers and load the latest ones from AMD.

We're going to try the stable base config and move from there.

Have you tried it with a single stick of RAM and just your Win10 boot drive connected and your GPU? The most barebones set up will help you troubleshoot.

I suspect it is the Team Group RAM

I have never used their RAM, but I have used their other products and my failure rate is in the double digits

Run Memtest on the RAM or remove the Team Group RAM and just use the Kingston

I've tried both the TeamGroup RAM by itself and the Kingston RAM by itself, and the problem appeared in both scenarios.

I don't have the event logs anymore (I wiped the Windows installation), but I did look at them. I recall that there was an error related to the TPM module following by several dozen warning messages at the same exact second. That led me to disable the fTPM in the BIOS, but that didn't seem to help with the freezing.

I was forced to upgrade my motherboard BIOS to the latest version available from the Gigabyte website in order to recognize the 5600x CPU.

I have gone to barebones only: CPU, M/B, RAM (various configs), AMD RX480 and SSD only with my Razer keyboard & Razer mouse; although they're connect through a built-in USB3 hub on my monitor.

Although i did plan to use spinning disks, those were taken out and returned to my old Intel Core i5-3330-based server for now.

I didn't use any XMP profiles for the RAM, just set it to default; and also did reset the CMOS at one point. I don't know how to set the JEDEC timings manually.

Not sure how much more barebones it can get from here. But as others have suggested, will try a different power supply and single-sticks of RAM.

Will also try out DDU, maybe it is a chipset driver problem in Windows; since it seemed to be stable under Unraid.

As others have metioned, the problem could be your RAM.
The issue could be that the memory sticks are installed in the wrong slots and your memory speed setting.
You have to set your memory speeds to the speed of the slowest memory.

Based on the manual, your motherboard has a backwards memory orientation so Slot 1 is the furthest from the CPU.
Starting with the memory slot farthest from the CPU (slot 1) and slot 3. Take the Team Group RAM and install in these slots.
Then in stall the Kingston RAM in the second pair of slots. (slots 2 and 4)
Boot into the BIOS and set the memory speed to 2133MHz.

Test and see if that works.

The problem with windows freezing/bsod is that it further corrupts windows. So even if you fixed the hardware issue, the windows install is already too damaged to continue any further troubleshooting. Would be best if you restored windows from a backup or reinstalled it.

I think I have fixed it.

Taking Canuck_TO's advice, I put the Team Group RAM into slots #1 and #3.

I also replaced:
* Kingston A2000 1TB M.2 NVMe with a spare, unused ADATA SP550 (250GB) SATA SSD, so that I could easily reformat the system without borrowing parts from my main desktop PC
* AMD RX480 8GB and put in a GT240; to remove any power-draw issues

Seemed to be stable. Did some data transfer operations over the network for a couple of hours to test stability, and it was fine.

Updated the AMD chipset drivers to the latest.

Then I installed the Kingston 4GB RAM into slots #2 and #4 for a total of 24GB RAM - boots and doesn't lock up
Put the AMD RX480 8GB back in to replace the GT240 - boots and doesn't lock up
Reinstalled the Kingston A2000 1TB M.2 NVMe, removing the ADATA 250GB SSD - boots and doesn't lock up

I'm typing this message from the booted computer now, with all the other USB devices hooked up.

Seems to be way more stable now.

My best guess is that the problem was with the RAM in the wrong slot.

I'll monitor for the next few days, and report back here if I encounter any further issues.

Thanks, all.

It might be applying the XMP timings from the high spec RAM to the lower spec RAM.

OKay, so this morning after rebooting the system, I was getting BSODs with the stop code as "MEMORY_MANAGEMENT" within 2-3 minutes of logging into Windows 10, same as what initially started this post.

Went into the BIOS to see if I could adjust the XMP settings, but there was no XMP option. I suspect this is because I was using two different sets of memory and the BIOS detected this and disabled XMP profiles.

I have had enough of this, so I went out and bought 2x16GB (XPG GAMMIX D20, 3200Mhz) and put it into the system. Seems to be working okay for now. Will keep things running for awhile and try a few more cold reboots to see.
