Hi.
So for a 1st time in my life I have switched to team Red.
And with all the benefits from it comes some things I have no clue how to resolve.

So after I finished the build all did seem to run fine for a most of the day until PC decided just to restart on its own.
The system was not under load just some light web surfing.
I tried to run 3dmark stability test /real-bench without any issues.
Did Memtest86 but only 1 pass without erros.
It does not happen a lot but 1-2 times a day in complete random moments.

I tried ram calculator for timings but with no improvment.

PC spec
Ryzen 3950x
X570 Taichi
32gb 4x8gb 4000mhz cl19 RAM
1000w PSU
970 evo 1tb
Raid 0 HDD
rtx 2080
nzxt x62

Any guidance on right direction would be much apriciated

Random reboots are not actually random. I bet you have a lot of WHEA errors. Check your event viewer. You can use hwinfo to track WHEA errors as well in real time. Once one happens you might get a string of them until the machine finally lets go.

Dram ram calc will only makes things worse when you have stability issues. Dram calc is for tweaking more perf out not the latter. That said, what speed have you set your ram to? Imo, this all comes down to your ram and what you have it set to. If I were you I'd set it to a slow speed and work up from there. And at that point you really have to understand that the ram you picked will require you the user to find the right speed/spot to run it at as that speed isn't ideal under Ryzen 2. *Edit realized I didn't make it clear that random reboots on Ryzen 2 is usually a sign of dram issues. That's usually what it is all else stock.

Only reason I used for dram calc was to be able to boot the system as XMP profiles does not work.
Atm did aida64 stress test with HWinfo opened to see if any errors pop up.
Attached image with ram speeds I have atm

Ofc the xmp profiles don't work, they are made for Intel. And as I wrote above, your dram sticks aren't for AMD. You will have to find whatever settings that work yourself. The screen above, you are running your IF overclocked and ram at 3733mhz. Why did you decide on that setting? Did you research this before? Runing the IF over 1800mhz usually requires adding voltage, so you'd better know this before hand.

You should set the ram to 3600mhz, and then find a relatively safe yet fast timing. Set that as your default.
 
So, you're running the memory at 3733 speeds? Is fclk at 1866 as well? That's typically on the edge of stability. Some people get lucky with 1900 fclk, but I've never had that luck. When I did run at 3733, I needed 1.47v on B Die RAM. Also, I would get failures to post with SOC under 1.1v. Right now, my 3950x is running with RAM at 3600. My RAM would also not boot at XMP settings which was 19-19-19-39 4000.
 
I just did watch couple video tutorials with x570 Taichi. Upgrade was not planed as I got the CPU and mobo for free so did not do my homework relating ram and ryzen. My knowledge about RAM ends after enabling xmp.
So I set SOC voltage on 1.1 RAM voltage at 1.4v and tried to apply ryzen calc safe settings.IF was clocked @ 3733Mhz afterwards did run stress test for an hour and it all did seem to be find until restarts appeared in my problem list.

Will try to set RAM on 3600mhz and see how it behaves during the day.

I wouldn't be using dram calc's settings until you are stable. Set it to 3600mhz and only put in the main timings of say 16-16-16-16 and leave the rest auto. A lot of the settings in the calc esp the misc items create more problems like gear and power down.
 
Got it working @3600Mhz CL16.
But I think RAM was not the issue .Now that I start to think the issue started to appear after 3.40 update and what I see from redit I am not the only one effected with same issue.It was running fine on version 3.0 with 3733mhz cl16 .At this point I just want to use PC so will stick with 3600 CL16 .

Thank you all for putting time on answering the problem.

About 3 months ago I rebuilt my rig with an ASUS ROG Strix-E with 3900X CPU and 2 x 16 GB of Crucial Ballistix 3600 RAM. For several weeks I would get these random reboots. No BSOD, just a complete random reboot. So finally I ran memtest for 8 passes and whaddya know,:eek: I had some errors. Crucial did the RMA no hassles.;) It's been two months now, rock-solid steady, not a single reboot. :)

I'm planning to tweak and overclock this system, but to be safe, I have run this system at BIOS 1408 stock settings. The ONLY changes I made in the BIOS were boot order and date/time. In about a month, I hope to have more time so I can do my tweaking, and maybe replace the Wraith cooler with something better. Also plan to reseat the chipset fan with better thermal paste. (y)
 
If you're not sure it's the XMP -- turn the XMP off.

If it still restarts, then it's something else (including maybe the RAM is bad)

Gotta rule that out first.
 
Downgraded BIOS from 3.40 to 3.00 did run memtest86 all night. No restarts so far and no WHEA under stress tests.So far loving my X570 Taichi but BIOS updates breaks more than it fixes.Running stable at 3733Mhz CL-16-19-19-19-37 1.4V

You should reach out to Asrock and make sure they're aware of the issue. You might help them revise the next BIOS update.
