ASRock A620M-HDV/M.2+ Max VRAM & lines of PCIe 16

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).

you can check PCIe lanes on chipset page and also depends on processor too like 8500G processor will provide lesser lanes than 8600G
