Solved! Go to Solution.
I checked and Bios 0207 is Update AMD AM4 AGESA V2 PI 188.8.131.52 Patch A.
Gonna try with DOCP off so ram is at 2,666 and see if I make it the day without a reboot.
My gut is telling me it's not the ram since memtest is passing at all speeds.
Maybe my Fabric Clock can't do 1600 when idling?
I can crash on demand now. Asus Armoury Crate -> Update Center -> ROG RYUO -> Update. Crashes half way every time. The RYOU is AIO Water Cooler with screen connected to USB 2.0 Header on MOBO to set Screen Display.
Guessing it is trying to communicate over USB to it.
Swapped RAM. Still crashes.
Downgraded to last NON Beta BIOS Version 1803, AMD AM4 AGESA V2 PI 184.108.40.206. Still Crashes.
GPU XFX Radeon RX 570 4GB
an old XFX Radeon HD 5450 512MB DDR2
Doesn't look like I can run the ROG AIO Cooler update again so I lost my reliable test for failure.
So does this mean RX 570 not compatible with 5600X? I can't buy a new video card now to try something else.
Guess I can try reseating the RX 570....
Well the old Radeon HD 5450 maxes out at 1024*768. Pretty much unusable. So I went back to my RX 570 @ 4k. Reseated, Swapped Modular power connector, Used different ports, etc.
10 minutes in reboots while look in Event Viewer for older WHEA errors. Made another one.
I have no idea what to do now. Can't buy a another video card.
My Radeon RX 570 has been running fine with my intel 3770K for years.
It's not the video card on intel.
It's the Radeon RX 570 video card on AMD Ryzen 5 5600X.
Upon further reflection the XFX Radeon HD 5450 working could have been a fluke and it's not exactly taxing anything running 19 watts @ 1024*768.
So I think it has to be CPU or Mobo (PCI Chipset). I pulled my AMD Ryzen 3200g running on my old b450 and am trying it with the RX 570. No reason I have to use the APU. So far no crashes but the night is young. Gonna RMA the CPU or the Mobo depending on whether I get crashes or not.
My 3200g runs SOLID with RX 570 as GPU. NO reboots. Zero.
So it is definitely something wrong with my 5600X CPU.
RMA Service Request: ticketno:.
Now I wait.
As part of RMA I had to reseat my 5600x to get pic with RMA # written on paper.
I guess it makes sense to try reseating cpu in case some dust or something got in socket.
Since I reseated I retested Thursday, and I was almost convinced it was OK at Stock non D.O.C.P Ram Speed (1067).
Ran 4 hours straight no reboots.
So I felt bold enough to try D.O.C.P. F-Clock from 1067 to a whole 1600! Brought up Youtube. Reboot.
Started thinking I needed to raise SOC voltage to 1.1 to get RAM stable for rated 1600 F-Clock speed.
Back to non docp speed with Fabrick clock @1067 Mhz, ram @1067 Mhz.
I have NO interest in an Overclock, but is 1600 Fabrick clock an OC to my ram @ rated speed?
Doesn't matter since it can't handle @1067 Mhz F-Clock reliably anyway.
Whatever is causing this has no pattern, except that no load causes it.
CPU ram tests, Prime 95, etc. max CPU speeed it runs solid.
It's happy with load. It likes the heat.
Stress tests are a total waste of time.
Youtube and Notepad are the new tests for stability on my 5600x.
idle almost nothing going on for all those cores.
That's what causes the reboot.
And it'll work every now and then.
Sometime for hours.
I'm back right now on the 3200g. My 3200g shows no Fabric Clock in Ryzen master, but DOCP up running RAM CLOCK @1600.
YouTube works solid.
2 days no reboots on the 3200g (Using RX 570 GPU)
5600x is going back.
I sent pictures Thursday night.
I was going to send my chip back as part of RMA# 2000310985, but I found my packaging, so I returned it to best buy and ordered a 5800x. I have also since purchased a 4700g (to upgrade my 3200g) and that also runs fine in this 550 mobo. When the 5800x comes in will update the saga.
