Can someone please explain?...r7 5700g OC

Hello guys,

 

I read something about the OC of the igpu :

"OC igpu from 2000--->2400mhz, with 1.35V which feeds BOTH the igpu and SoC"

 

My r7 5700g OC is 1.4V on cpu and 1.35V on 2400mhz igpu, i didnt understand, should my cpu V and igpu V be the same. How does it work?

I can't assist you in overclocking your APU. I was just trying to answer your original question.

If you have any questions about overclocking or underclocking your APU go to these types of websites for help and open a thread there:

Moth-TLOU2, I am not a graphics person but SOC (System On Chip) in Ryzen is used for many internal things, it is separate from the cores users run code on. Only AMD runs code on the SOC. Why the SOC voltage is tied together with the IGPU I do not know but I assume they are in the same power zone on the chip. Changing IGPU voltage should not change the Core voltages. Enjoy and enjoy, John.

From a 2021 Tom's Hardware article about overclocking your APU processor: https://www.tomshardware.com/features/ryzen-5700g-overclocked-world-record

Concerning IGPU and SOC Voltage from above link:

Overclocking the Vega 8 integrated graphics (iGPU) core frequency is pretty straightforward: Increase the voltage, increase the clocks, and decrease the temperature. SOC voltage, which also helps with overclocking the system memory, will be the main one to focus on. The vGPU voltage is also supplied by SOC voltage, so it's best to keep it a little bit under your SOC volts. The max scaling I saw for the iGPU core was right around 1.37-1.39V. This was enough to run FireStrike at 2425 MHz, a +20% gain in frequency!

What about leaving the igpu stock with auto V whilst cpu is manual V. Is this wrong
