AMD5 X607E Hero with 7950X3D and 7900 XTX keeps randomly shutting down

[Philak]

Hi All,

I'm wondering if anyone would be able to help with some issues I keep having with my PC over the last year. It has moments of stability but then will seemingly randomly begin having problems again where the PC will just shut off entirely with no errors. Looking in the event viewer as well there doesn't appear to be any errors. I've monitored the temps and even when under load the CPUonly hits mid to high 70s. Originally I thought it may be down to the RAM as it was optimized for intel (CMK32GX5M2B5600C36) . So I recently switched that out (CMK32GX5M2B5600Z40) and the system became even more unstable never being able to stay on for more than a few minutes. I've had issues ever since I built the PC on and off at first just updating the BIOS seemed to fix it but it's now becoming more and more frustrating. The specs are below and any help would be appreciated:

• Asus ROG Crosshair X670E Hero (Socket AM5) DDR5 ATX Motherboard
• AMD Ryzen 9 7950X3D Sixteen Core 5.70GHz (Socket AM5) Processor - Retail
• Sapphire Radeon RX 7900 XTX Nitro+ Vapor-X 24GB GDDR6 PCI-Express Graphics Card
• Corsair Vengeance 32GB (2X16GB) DDR5 PC5-44800C36 5600MHz Dual Channel Kit - Black (CMK32GX5M2B5600C36) x 2 
• Seagate FireCuda 530 2TB SSD PCIe Gen4 NVMe M.2 Solid State Drive (ZP2000GM3A013)
• Seagate FireCuda 540 1TB SSD PCIe Gen5 NVMe M.2 Solid State Drive
• CORSAIR HXi Series HX1000i Fully Modular Ultra-Low Noise ATX Power Supply (CP-9020214-UK)

Hello Philak,

I have something you can test, see if this resolves your system randomly shutting down issue.

If your not on current BIOS version then please update to current version. Set default settings, restart into BIOS.

Enter the PBO submenu and set Curve Optimizer to all cores, to [ Positive 6 ].

Save, restart, boot into Windows. 

Run your system, performing daily tasks,.. see if this resolves random shutdown issue.

I completely forgot to respond to this but doing that seems to have fixed the issue and I haven't had any further reboots since, thanks for the advice

Plz Uninstall the armoury crate and all problem solved

I have a similar issue with an Asus X670E Pro Art Creator motherboard with 7950x. The system will abruptly shutdown without warning or any errors outputting to the syslog. The only remedy to reboot the system is to flip the master power on the PSU. I have recently reset the Bios to optimized defaults and disabled the "Global C-State Control." SO far, 14 Hours of uptime.

My system crashed shortly after my post. I removed all external connectors, re-seated the GPUs, and removed the backup BIOS battery. Upon restart, I loaded the optimized defaults and adjusted the following parameters. Under Ai-Tweaker\PBO\Curve Optimizer:

Curve Optimizer: All Cores

All Core Curve Optimizer Sign: Positive

All Core Curve Optimizer Magnitude: 6
