ROG STRIX X570-F GAMING BIOS 3001
"1.New CPU support
2.Add a ReSize BAR shortcut for AMD SAM support




1 就是相容ZEN3 CPU。
2. SAM

想了解ZEN2 向3000X系列的CPU完全沒機會用到SAM技術嗎?

是的 3000系目前無法使用
沒法

看其他論壇的某些討論是提到因為ZEN2當初沒有實作需要的相關電路進去所以...

我知道其他報導說沒辦法支援。
這報導說有實測過,只要主機板商BIOS支援,ZEN2就可用SAM。
不知其他網友是否開關看一下FPS差多少應該就有答案了。



Our GPU test system, which uses an ASUS X570 Crosshair VIII Formula, now has a BIOS update which adds support for a feature called "Resizable BAR", the cornerstone of AMD's Smart Access Memory (SAM) feature, and it would be rude not to test it out on our Ryzen 9 3950X.

With a Radeon RX 6000 series graphics card and an motherboard/CPU combo which supports the optional PCIe "Resizable BAR" feature, gamers can see significant uplifts in game performance in some titles, effectively giving PC users a free performance upgrade. In this overview, we will be testing Smart Access Memory using our Ryzen 9 3950X Zen 2 processor across a large selection of games to judge the performance impact of the feature.
