Hello! I'd like to buy motherboard ASRock A620M-HDV/M.2+.
But I need to be sure in 2 important moments of this motheboard:
1) What is the max volume of VRAM using by intergated graphics in CPU?
2) WHat is number of PCIe 16x lines in fact. 16 or less?
Thank's for helping. :)

I was able to assign 4GB to mine (9800X3D). It was hidden away in the BIOS setting, and I don't remember exactly where.

I think there's a way to manually specify the amount, but I don't know what the max is.

I don't know if this is up-to-date, but according to that list, 4GB is max. Surely, there's got to be a manual setting to give it more (if you have lots of DRAM).
