Contrary to what marketing materials suggest, it appears that AMD’s Smart Access Memory (SAM) feature may not be exclusive to 500 Series chipsets and motherboards after all. ComputerBase has reported on the findings of German YouTuber RawiioliExtras, who recently tested ASRock’s new BIOS updates and discovered that the latest AGESA enables SAM support on his B450 Steel Legend motherboard.
“With the latest BIOS updates and AGESA v2 1.1.0.0, in addition to the Zen 3 CPUs Ryzen 9 5950X, 5900X, Ryzen 7 5800X and Ryzen 5 5600X, the Smart Access Memory for X470 and B450 is also activated,” ComputerBase confirmed. “Most recently, the corresponding BIOS versions from ASRock made the Ryzen 5000 series (test) executable on B450 motherboards.”
AMD’s Smart Access Memory feature grants Ryzen 5000 Series processors full access to Radeon RX 6000 Series graphics cards’ GPU memory. According to red team’s internal benchmarks, the feature can provide up to an 11 percent increase in select titles (e.g., Forza Horizon 4).
