System error encountered.
The system began functioning about a week into use. It won’t power up after leaving it off overnight. A quick restart or turning it back on shortly fixes the issue. Currently, I start up by performing three power cycles. During the first boot this morning, I see a BIOS splash screen, but I can’t access the BIOS settings. Once the screen clears, there’s no display output. I suspect the problem lies with the video signal after the splash. BIOS settings show an XMP profile for the RAM CPU OC 4.7GHZ @1.298V (stress tested without crashes), FTPM 2.0 is enabled, and SVM Activated (Virtualisation). LAN PXE ROM is available, and the boot option is set to ROM. PC specifications include a B550 Aorus ELITE AX V2 motherboard, R7 5800X CPU, Gigabyte Gaming 3080Ti GPU, four 16GB Team Group Delta R RAM at 3200MHZ (XMP), storage options of two 8TB Seagate Ironwolf drives, one 256GB Gigabyte NVMe drive, and a 256GB Samsung SATA SSD. The CPU cooler is an iCUE H115i ELITE CAPELLIX unit, and the case fans are MF120 models from Cooler Master. The PSU is a Corsair RM 850W unit. All components are wired to the fan hub, with the RGB header directly connected to the motherboard. There’s a Windows 10 and Ubuntu installation on the SATA SSD, but the boot sequence in BIOS directs it to the NVMe drive image named IMG_2913.HEIC.
You've already checked several fixes—re-seating RAM, trying other configurations, disabling BIOS OC, and booting in AUTO. Still facing the same problem. Could you share more details about your system model and whether it's a recent release? This might help narrow down the solution.
It seems the voltage might be too low. Overclocking the RAM could be the issue. I’d suggest raising the SOC voltage from auto to around 1.15v.
Apologies for the oversight, I omitted the CPU overclocking. The RAM operates smoothly with the XMP profile. After restarting into Windows and running a stress test, the CPU overclock performed well. I also handled compression, decompression, workloads, and gaming tasks on those specific settings. The RAM is functioning at 1.35V.
SOC voltage stands apart from CPU voltage. It manages the power levels for your IMC or Memory Controller. Focus on turning on PBO2 and tweaking EDC settings to achieve the right balance. Adjusting Ryzen chips via manual overclocking is usually not recommended.
Yes, this was true even for Ryzen 1000 and 2000 models, but 3000 and 5000 generally outperform manually with PBO. The main issue with manual over PBO is the single-core boost advantage. My 5900X achieves over 5GHz single-core and 4.6-4.625 on all cores with PBO.
