AMD Ryzen APU issues with ASRock MB motherboard.
AMD Ryzen APU issues with ASRock MB motherboard.
Hello there,
I just received the parts for a brand new PC:
Spoiler
Ryzen 5 2400G
ASRock B450 Fatality Gaming K4
2x8 HyperX 3000MHz CL15 pack (QVL - HX430C15PB3K2/16)
DeepCool DQ550ST PSU 80+ Gold
And a budget case with good airflow (already tested, came with 3 fans front and 1 rear)
Assembled everything, updated the BIOS to version 1.50, activated my XMP profile at 3000MHz, then lowered the RAM speed to 2933MHz as I've heard Ryzen doesn't prefer that speed. After spending about 6-8 hours installing Windows properly for these new APUs, it worked fairly stably. Thank you for your help! I still had some minor issues here and there, occasional stutters, but that's normal.
As usual with such builds, I attempted a bit of overclocking. First, I checked everything at default settings, then ran MemTest86 for over 17 hours to ensure RAM stability. Everything went smoothly – no problems detected. The Wraith Stealth cooler kept working well, so I didn't push the OC too hard. I left the RAM as it was, since it performed reliably. I spent some time tweaking the BIOS, adjusting clock speeds and voltage settings, but nothing significant changed.
I decided to monitor performance with tools like CPU-Z, AIDA64, and HWMonitor. The results were concerning: the CPU core voltage was fluctuating between 1.42V and 1.56V without any changes to clocks or voltage. I turned off Cool'n'Quiet (a feature long gone for AMD users) and set the XMP profile. The VDDCR_SOC stayed around 1V, with a slight variation of ±0.075V.
From what I learned from past builds, these readings were unusual. I experimented with Ryzen Master to try boosting the iGPU clock, but it led to frequent crashes and TDR errors. I increased the TDR value in the registry, disabled SVM and C-state controls, set the CPU clock to 3600 and voltage to 1.4V, added a +150mV offset to the SOC, and left the GPU settings as "Auto."
The results were mixed: VDDCR_SOC stabilized at 1.208V (sometimes dropping slightly), and temperatures under load decreased by about 10°C.
After further adjustments, I realized I couldn't overclock the iGPU beyond 1300MHz without triggering TDR errors. Running the CPU at 3900MHz with 1.4V was manageable, but even then, temperatures stayed around 74-76°C after extended stress tests (lasting 1.5 to 6 hours).
In short, my goal wasn't to push the iGPU beyond stock speeds. I wanted better graphics performance, but it seems I hit a physical limit.
Any advice would be appreciated!

This post caught my attention. I found it intriguing! I’m curious to know more about it. For those who don’t know, I’ve only heard of "Black Hole" in the context of overclocking before. I’m not a big fan of deep technical dives, but I’ve experimented occasionally when necessary.
So far, my 2400G has performed well, running Heaven and Cinebench R15 at 1500MHz with 1.25V on the graphics settings. I kept the +100mV offset for the SOC in the ASRock BIOS, though that might be excessive. The system remained stable, but it crashed at 1550 and 1600 MHz with the same voltage and offset. It didn’t crash during Windows startup, unlike previous attempts between 1350 to 1450 MHz. Temperatures stayed within a comfortable range, around 60-64°C during testing.
Thank you for sharing this! I’ve been learning more about Ryzen APU overclocking lately, but I didn’t realize it was this interesting topic until now :lol:
