Ryzen 5 Pro 4650G always revert iGPU to 512MB

Hello guys,

I have a Ryzen 5 Pro 4650G, on a system with Gigabyte a520M motherboard with 16GB or DDR4 RAM

(IN BIOS) i have set the RAM for XMP Profile 1, 3200mhz and i set the iGPU, using the AMU menu

i change it from Auto to AMU_Specific and set it to 2Gb

but after i save the settings, everything is saved but the iGPU will always turns back to Auto

and in Windows it will always shows 512MB of Vega 7 

is this a feature, a bug, and is there a way to make the iGPU to 2Gb?

Honestly I think that would be a motherboard issue. I would ask Gigabyte support about that. You might check if they already have a newer bios available for your board and load that first if so. 

Good Luck!

as mentioned its a Gigabyte BIOS issue!

Gigabyte had bad BIOS since X370 (i dont know why)

PC: R7 2700X @PBO + RX 580 4G (1500MHz/2000MHz CL16) + 32G DDR4-3200CL14 + 144hz 1ms FS P + 75hz 1ms FS
Laptop: R5 2500U @30W + RX 560X (1400MHz/1500MHz) + 16G DDR4-2400CL16 + 120Hz 3ms FS

The video memory of this processor is able to use a maximum of 2 gigabytes. If you set 4 gigabytes in the BIOS, the default memory will be reset to 512 megabytes. Set the vram to 2 gigabytes and everything will be fine.

A future project of mine is getting the X300W barebones mini-PC (literally fits in your hands it's that small) from ASRock and slapping a 4750G or better into it. It's a ultimate tiny little destroyer of a system, only costs about $1000 US too to fully build .
