Solutions for VEGA 8 overclock issues
Hi everyone, I have a RYZEN 3 2200G overclocked to 3.8ghz from the BIOS, MSI B450m pro M2 V2, 8GB 3000MHz (XMP 2933), Deepcool GammaX 400, FSP Hexa 400W. I attempted to overclock the iGPU Vega 8 as shown in many videos and forums. Everyone can manage the Vega 8 up to 1400/1500/1600 MHz, but when using RYZEN Master software I restart my PC yet I always see a black screen (the PC is still running). So I need to reset the CMOS every time. I tried various voltages like 1.3 GFX and 1.2 SOC voltage (and lower) but it didn’t work... anyone can help me? I’d appreciate a frequency around 1300/1450 MHz for the IGUI.
Auto voltage has no restrictions. The CPU/IGPU determines its requirements and sends them to the VRM. If it needs 1.6v, it will demand that, regardless of whether it uses 1.2v or 1.4v actual. That’s why people set voltages manually. Lower voltages reduce heat, but there are also safety limits they avoid crossing with OC and other components.
Every CPU reacts differently to voltage levels. The values shown in the video are just suggestions; you might need 1.32v for a CPU or 1.216v for a SoC. Following another CPU’s settings exactly often causes black screens.
Begin with auto mode, observe the VRM and BIOS configurations for voltage settings at OC/speeds, then adjust them manually. Gradually experiment with different voltages to find what works best.
I attempted the latest BIOS (compatible with Ryzen 3000) and also tried the older one 7B84v41, but it didn’t work. Can you assist me?
I used the BIOS and it works! Now I need to experiment with voltages for the graphics and main processor. A tutorial suggested 1.3 V for the graphics and 1.2 V for the main processor. With the Vega 8 at 1500 MHz and a graphics voltage of 1.2, I keep the main processor voltage unchanged. These values seem connected according to the tutorial. I'm running superposition tests for benchmarking and stability analysis.
The performance benefits from reducing the CPU frequency from 3.85GHz to 3.8 or 3.75GHz depend on your specific workload and system configuration. Lowering the frequency can help save power, reduce heat generation, and improve battery life in mobile devices. However, it may also result in slower performance for tasks that require high computational power.
Read this article and watch the video. It should assist you more effectively than trying to explain it in a long explanation.
