After flashing the A04 version BIOS to BA-206, when I set UMA as 32M,64M,128M and SIDEPORT always set as 128M in UMA+SIDE PORT enabled mold and then test benchmarks by using GPU-Z0.3.4, it will show the benchmark as 64M,112M,208M , but the correct figure should be 160M,192M,256M!

Upgrade BIOS to A05
