Asus has allegedly enabled AMD Orderly Gain admission to Memory (SAM) on first-generation Ryzen CPUs, in step with a Reddit particular person.
AMD’s SAM honest facilitates the CPU having fleshy bring together admission to to GPU memory, lifting particular memory constraints and giving substantial efficiency features of as a lot as 10% in some video games.
SAM currently handiest works with AMD’s Tall Navi graphics cards in tandem with Ryzen 5000 sequence processors and a 500-sequence motherboard, and it used to be believed the honest wouldn’t come to older chips resulting from the methodology they handled a particular instruction (PDEP).

However, now not handiest has AMD confirmed that SAM doesn’t count upon PEDP, but some board producers relish honest now not too prolonged in the past extended toughen on AMD’s 400-sequence and furthermore Intel’s 400-sequence motherboards.
Now, we’re seeing motherboard distributors enabling toughen for SAM on first-generation Ryzen CPUs. Reddit particular person Merich98 claims he bought the honest to work with an AMD Ryzen 7 1700 CPU operating on an ASUS B450-PLUS motherboard that used to be operating the most neatly-liked 2409 BIOS which launched in early December.
Merich98 furthermore examined the efficiency in Doom Everlasting and Shadow of the Tom Raider. However, the outcomes aren’t all that promising, and demonstrate that SAM doesn’t originate great of a difference in efficiency.
As an instance, with AMD SAM disabled, Doom Everlasting ran at an moderate FPS of 125.6, rising to honest 125.9 FPS with SAM enabled. Total, the Reddit particular person notorious an moderate FPS expand of honest 0.839%, while the minimal FPS dropped by 6.2%.
“As you might relish, loads of the diversifications are internal the margin of error while the minimal FPS prefer a huge hit which signifies efficiency degradation with AMD Orderly Gain admission to Memory enabled on an older generation graphics card,” the Reddit particular person notorious.
