Hi all, Please see the below text for the method of which I have come to my conclusion regarding the faulty ASRock AB350M Pro4 boards. Conclusion The cause of the well known freezing/lock up with this board, or maybe just defective versions, is that there is problems at the low level with regards to memory. The BIOS settings also appear to become corrupt upon freezing and change the values of memory profiles and general memory settings, such as having overclocking enabled. This has been tested over two sticks of RAM. Two motherboards. Two CPU's. Live USB Linux. With minimal hardware connected. The current status is that the board is being sent for testing by ASRock. I will be expecting another board for this to frustrate me shortly. Update 7 - 01/02/2018 I changed the CPU. It was stable for approximately 6 hours and then the usual symptoms. In this update, I will reiterate the things worth remembering, and what steps I have completed to try to resolve the problem. Symptoms The machine locks up and freezes completely, seemingly randomly. This is not just a Windows 10 issue, unless Windows 10 has managed to affect low level hardware. This is due to the fact that I have dual booted with Linux, and that nor a live usb stick with an OS on worked. They all froze. The system is more stable after leaving it off overnight. It will last approximately 30m to 1h. After you experience the first freeze, it can happen every 20 minutes. Running memtest86, the problem would actually cause this utility to freeze around the 19-20 minute mark every time. This was around Test 10: Sleeping. Just before hammer test. I purchased another stick of RAM and ran memtest86. It got further. But 2nd pass, it froze again. No errors ever detected with either stick of RAM. Suspicions and Potential Root Cause Every time my computer would freeze, I would notice that my BIOS settings would change. Only the memory profiles. The overclocking would be enabled, and anything relating to voltages would change to 1.2V. No matter how many times I would save them, they would seemingly corrupt, or revert. I tried P3.00, P3.30 and P4.50. All versions did the same thing. When I would load Windows long enough to view A-Tuning utility (I don't overclock by the way, I used it for diagnostic purposes), I would notice that the DRAM voltage wouldn't have a reading. The value was not set. Therefore I suspect the issue is surrounding memory management, and memory profiles at the lowest level. I am sure there are issues with operating systems and this board/CPU, but this is clearly not one of them unless somehow Windows is always running some processes very early... somehow. My board is set to be sent to the Netherlands, and further to Taiwan. I don't suspect this will be fixed soon. Though, I am set to receive my third board in two weeks, and this will be my second CPU, and second stick of RAM. It is worth mentioning that I have removed all other components and peripherals in order to diagnose this. Only the essentials were used. Especially in the case of the live USB crashing, I didn't have any SSD or HDD connected. It would load, and freeze after some usage. Finally, it is important to note that I cleared CMOS regularly between BIOS flashes in order to definitely determine the corruption of BIOS data after freezing. Update 6 The new board made little difference. I suspect the CPU must be changed. Update 5 - 26/01/2018 Away for the weekend, I stopped the machine from going to sleep so that I could remote desktop in to it. This was working fine up until 00:22 according to its online status. I can no longer connect to the machine, and I am unsure of the particular reason until I return home. I worry that this defect may be causing the machine to heat up too much and when I return it will be overheating. It could be a case of Windows Updates, but usually the machine would restart and reconnect to the network. Update 4 I have replaced the board and thus far there are no problems. I noticed in the Windows 10 power saving settings that now I have an option that says 'AMD Ryzen Balanced'. I am very sure that this was not there before. I have not changed the BIOS from the version that it shipped with, and that is version P3.0. Though, I may try this in the future. I ran a GPU stress test with OCCT and it got to 40 minutes with no problems. Previously it froze at 08:29. That doesn't indicate that was the cause, but loading games would also freeze it more often, despite pulling the GPU and reentering it in to the slot. Again, this still may not be resolved as the issues previously didn't manifest until around 3 days in to usage. Update 3 - 23/01/2018 I have noticed that when I load a game, it tends to lockup/freeze more. That doesn't mean it is the cause, but it might indicate something. I decided to run some mining software to try and stress the GPU a bit more, seeing as how OCCT froze around 08:29 minutes in to a test. I notice that when I terminate the mining software, for some reason the system locks up completely. This might be worth exploring further. Update 2 - 22/01/2018 The previous update steps did not work. I was also using OCCT and it appears to have frozen 08:29 in to a 1 hour GPU test. Update 1 - 22/01/2018 The system is stable since turning it on, after having it powered off all day. I do not know why. I have installed Windows 10 updates via USB, and I am currently downloading some more through the usual Windows 10 method.
On to download and installation... Original Post Components Motherboard: ASRock 350m Pro4 Processor: AMD Ryzen 5 1600 w/ stock cooling (not overclocked) RAM: Vengeance LPX DDR4 2400Mhz 8GB SSD: Crucial MX300 275GB Network Card: Gigabyte GC-WB867D-I PSU: Corsair TX550M 550W GPU: EVGA Nvidia 1060 GTX 3GB S Gaming Description of Problem The issue itself is the PC locking/freezing up but with power remaining on. Sometimes the screens will switch off. Sometimes they do not. The mouse and keyboard no longer are responsive in this state. I built this machine five days ago, without issue until 2 days ago. For 3 days, there were no problems. There is no set time for this, it will happen whether idle, or performing a task. It has happened when attempting to load a live USB stick with an operation system, or when the OS is loaded. But I have not experienced this when in the BIOS, before attempting to load an OS. This is on both Windows 10 and Linux Mint in a dual boot using the GNU Grub boot selection software. When this happens, I must hard reset the machine. Diagnosis and Fix Attempts
Future plans include plugging in an old HDD, and installing an OS on there, whilst the SSD is unplugge

I'm going for PSU here.
The Corsair TXM550M, from using my Google Fu anyways, looks to be an older model. Guessing the rail outputs are more P4 ready than that for newer systems. Please post a pic of the Spec sticker located on the side of the PSU itself please. |

I'm away from the machine at the moment, here is a table from the spec sheet. The URL for this can be found here: http://www.corsair.com/~/media/corsair/download-files/manuals/psu/txm_manual.pdf Is this what you were looking for? I'm not sure what P4 means, unfortunately. I am a bit on new terrain with PSU's. I tend to understand the other components more. However, would an electronic fault manifest 3 days later? Every time a new board is fitted, or CPU, or RAM, it takes much longer for the issue to appear. Edited by mpw - 02 Feb 2018 at 5:19am |

Thx for the clarification.
Power or a shorting issue. Did it behave this way when you had built it outside the case? If it did, I here would be getting a different PSU to test with. You've done everything BUT consider the PSU. That seems to be the constant across all you've done. The PSU remained the same. |

Would a shorting issue allow the monitors to remain powered? I am not great with electronics, but wouldn't a short mean that eventually the capacitors in the motherboard would discharge, and we would see the system turn off? I haven't actually tested outside of the case, which is something I will do, should this new board not work when it arrives. Is this always recommended, and is there anything wrong with the PSU touching the case? I understand sometimes there are little rubber inserts that can be used with a PSU. To be fair, the GPU is also only slightly tested. I cannot test without the GPU due to the system not allowing for integrated graphics. Though, the freezing doesn't seem consistent with stressing the GPU. Of course, this does not rule it out. There is also every possibility that this is in fact a problem with a subset of AB350M Pro4 boards.

Should you have a short at or on the MB itself, sure, the monitor could still stay powered. Remember, the monitor has its own supply and is only dependent on the data the monitor cable supplies. Build it out on a non-conductive surface outside the case, using due caution obviously, and post back if you can duplicate the behavior you see while assembled in the case. |

Update: the issue was that I had FOUR, yes FOUR, faulty ASRock AB350m Pro4 boards. The GPU in the PCIE Slot 2, (i.e. PCIe Gen3 slot) was causing issues for the board.
I have new issues with the board, but it is not freezing as it used to. It is mostly related now to BIOS not storing values, and overclocks not holding. Stocks speeds are presenting stuttering in games with all other hardware removed where appropriate.

Hi, I guess I'm having the same issue as you here. I just bought all the components a couple of weeks ago, already changed the motherboard to another ab350m pro4 and keep having the same issue. So is there a way to solve this or I should just return it? I am still in time to return the mobo and buy a different one.
