Vhiki rino, vagadziri vebhodhi reamai vakatanga kuburitsa shanduro itsva dzeBIOS dzeSocket AM4 platforms, zvichienderana neshanduro itsva ye AGESA 0070. Zvigadziridzo zvatove zviripo kune vakawanda ASUS, Biostar uye MSI motherboards inobva pa X470 uye B450 chipsets. Pakati pezvinhu zvikuru zvitsva zvinouya neshanduro dzeBIOS idzi "rutsigiro rwevagadziri venguva yemberi," izvo zvinoratidzira kutanga kwechikamu chekugadzirira chevashandi ve AMD kuburitswa kwevamiriri vemhuri yeRyzen 3000 - iyo inotarisirwa 7-nm machipisi akavakirwa pamusoro. Zen 2 zvivakwa.
Chiitiko chakakosha chakadaro hachigone kufuratirwa nevanofarira, uye BIOS nyowani yeimwe yeBiostar board yakaparadzaniswa nevashandisi veReddit. Nekuda kweiyo reverse engineering, zvimwe zvinonakidza zvakaziviswa. Uye chishamiso chikuru ndechekuti iyo UEFI BIOS menyu ine basic processor marongero, yaimbonzi Zen Common Options, ichadaidzwa kuti Valhalla Common Options kana maCPU matsva akaiswa mumabhodhi. Uye izvi zvinogona kungoreva chinhu chimwe chete: AMD ichashandisa zita rekodhi Valhalla sezita rezvivakwa zveramangwana Ryzen 3000 kana chikuva chavo.
Pane imwe shanduko yemazwi. Panzvimbo pechidimbu CCX (CPU Core Complex) yemamodule achaunganidzwa kubva Ryzen 3000, pakasiyana chidimbu chinoshandiswa - CCD, ingangomirira CPU Compute Die (CPU computing crystal). Shanduko yematemu mune iyi kesi inoruramiswa, sezvo mune ramangwana processors ese maI/O controllers akaendeswa kune yakaparadzana 14 nm I/O chiplet, nepo 7 nm processor chipsets ichange iine chete computational cores.
Nehurombo, iyo BIOS kodhi haina kupa nzwisiso pane iyo yakawanda nhamba ye cores inogona kuwana remangwana Ryzen 3000. Rondedzero yezvigadziriso ine sarudzo dzinokutendera iwe kushandura uye kudzima kusvika sere CCDs, asi zviri pachena kuti chidimbu chekodhi iyi. yakakopwa kubva kuBIOS yeEPYC Rome - server processors , iyo inogona kunge iine machiplets masere ane processor cores.
Kuonekwa kwerutsigiro rweRyzen 3000 muBIOS yemabhodhi eamai kunogona kureva kuti AMD inoronga kutanga kutumira maenjiniya masampula ekugadzirisa uye kusimbisa masisitimu munguva pfupi iri kutevera. Nemamwe mashoko, gadziriro dzechiziviso dziri kufambira mberi, uye hapafaniri kuva nokunonoka. AMD inotarisirwa kuunza desktop processors zvichienderana neZen 2 architecture mukutanga kwaChikunguru.
