Side note if I set 3GB it does work but if it will not work over 4gb, If I enable UMA over 4gb option to true the front panel USB my case will stop working

What version of Windows ..ie .. Windows 7? 10? 32bit? 64bit? 1 x 16gb stick or 2 8gb sticks? ..per the manual ?? Shared memory default 2GB, Max Shared memory supports up to 16GB. * The Max shared memory 16 GB requires 32 GB system memory installed. sooo .. if you are running Windows 10 64bit and 2 x 8GB sticks of matching DDR4 .. you shouldn't have a problem with 4GB of shared memory for video ------------- |Ryzen 5 5900|ASRock X570 Taichi-BIOS 4.60|2x16GB HyperX Predator RGB 3200@3600 1:1 IF|ASRock RX 6700XT|2 x PCIe 4.0 M.2 Drives for OS & Games|850 WTT Seasonic 80+ Titanium PSU|Noctua NH-D15| |

| any updates on this? I'm planning to to build a budget PC with Asrock as my board. Maybe other options will only appear if you have 32 GB and up RAM? |
