sometimes the UMA Buffer Limit is also mentioned in Motherboard's User Manual on their respective websites. another way to find out the max vram limit.

Thank everyone for helping. I finally bought the motherboard.
I've found in GFX options UMA buffer size, but before it needs to activate GFX configuration as specified. I'm very happy that this A620 motherboard can support up to 16Gb UMA buffer size. Because of this there are very good results in games such as Forza Horizon 5 (60fps in 1080p mode). I had some thoughts of that motherboard can support no more than 2Gb VRAM. |

asrock b650m bios shows max UMA Buffer size 16GB, screenshot
 you can check PCIe lanes on chipset page and also depends on processor too like 8500G processor will provide lesser lanes than 8600G https://www.amd.com/en/products/processors/chipsets/am5.html |

you need to switch to UMA_SPECIFIED in GFX menu. |

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). https://community.amd.com/t5/pc-processors/can-i-adjust-the-video-memory-size-with-ryzen-9-7900x3d-with/m-p/653165 |

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. :) |
