原本大家說要等到25號的正式版神油驅動
沒想到昨天就放出來了,號稱第一版正式支援VEGA的缺動,當然小弟也要玩下
(為啥版上都沒人討論?)
先講結論:AMD驅動是猴子寫的嗎?風扇速度完全不能調
雖然調主頻跟記憶體的能調間隔有變大(之前都只能慢慢調不然會鎖死)
但那個風扇...為什麼預設頻率再怎麼熱都只能49%轉速?
要手動超頻才會開啟50%以上的轉速?
在預設頻率的情況我有發現,只要跑到核心83度以上時,主頻跟記憶體就會因為過熱而
降低。因為用遊戲測試可能不太準,因為有不同場景的變動,所以我是用挖礦程式來看的
剛開ETH挖礦程式可以瞬間37~39Mh/s 但開一陣子後就只剩30~33Mh/s
我真的懷疑是過熱降頻的影響 AMD不希望預設不超頻時風扇就全力運轉 所以才會鎖49%
轉速,但你他媽的預設就過熱了啊!
接下來小超 把記憶體頻率從945微調到1000時,居然風扇就馬上轉到了90%!瞬間吵爆!
上次也提過了VEGA可以弄到40~43MH/s(瞬間功耗4XXW),但那絕對都是100%全開的情況,
公版散熱整個烙賽,驅動更是拉機。
我推測這個熱度,市面上的銷庫存三風扇AMG非公也可以不用買了,已經入手公版的,
與其等更好驅動出來,不如直接想辦法自己改散熱比較實在。
畢竟是電蝦版,一般玩家請等水冷版吧,上水冷這張一定會變很強(至少不會降頻)
對不怕吵的免電礦工來說,這張也還是目前算力最強的,還有上看50的潛力,而且感覺HBM記憶體
效能AMD完全沒用到一半的效能...自己的神油驅動礦工請自己寫
--------------------------------------------------
補充:我覺得最拉機的原因是風扇完全不能手調
目前AMD驅動的風扇邏輯就是:
"只要沒停止升溫,就飆轉速"
偵測給的緩衝時間根本沒有,所以他媽的調一點點幾秒內瞬間爆衝到90%(預設鎖49%)
有版友水球跟我說從Fury第一代HBM開始超頻就要降壓了,我這幾天再試試
或許能調出不熱又安靜的模式 誰想在飛機場打電動阿...
