Questions regarding iGPU overclock

[Hold-Ma-Beer]

My specs:

Ryzen 3 2200G overclocked at 4.0GHz

Integrated Vega 3 at stock 1100MHz

Corsair Vengeance LPX 2x8GB at 3000MHz

Gigabyte B450 Aorus

So basically, I've overclocked my CPU and wanted to overclock the iGPU, but found out that my motherboard does not have heatsink on VRMs of SOC. When any kind of voltage is added on the stock 1.1V SOC, the temps on VRM goes around 100C. So, I have the following questions, kindly help me out

 

1. Does SOC voltage have to do anything with overclocking iGPU?

2. What is APU GFX?

3. Which one of these voltages should I increase while overclocking the iGPU if I experience drop in CPU speeds?

1. Yes. SOC voltage affects the IO die/ interconnect and that has the i-gpu. 

2.  Could be wrong, but seems like the apus frequency. 

3. you could focus on the SOC voltage.

If it doesn't throttle anything at 100c then it won't hurt anything, mosfets are usually rated to run at higher temps. But if it does throttle, you could point a fan at them.

Any kind of voltage increase results in going near 100C, and for overclocking my iGPU, I've to set it to 1.2V from 1.1V. So it reaches 120C and system crashes.

 

 

From the tutorial videos I've seen for overclocking 2200G, they increase the APU GFX voltage as well. So, I was wondering if I could overclock the iGPU by only increasing the APU GFX Voltage?

Yea then you can point a fan at the soc portion and check temps.
