No "Large Memory" line in Device Manager #230

|
Hello! I have a bit odd setup but I think it should work, and at first I thought it's all good because Adrenalin and GPU-Z show rebar Enabled. But later I found that in DM there is no line "Large Memory Range". So is it 100% means rebar/sam is not enabled? What else can I do about it? What I did: added FFS module in MB bios with UEFITool, updated UEFI on GPU, installed Windows 10 in UEFI/GPT mode, turned on Above 4G decoding in MB's bios, changed registry keys to enable sam in AMD driver, set ReBarState value as 32 - black screen in Windows, 12 - same, 11 - seems good. |

ReBar works. I tested in a few games, there is consistent fps increase +5-8% in two games, in one game no difference. Also I found out that Large Memory Range appears in GPU resources only If BAR size set to 4GB or higher. |
