x470 i
x470i 可以上3600
請問要幾多 v
1.4v ~1.45v 自己試
不過建議你改下上面用詞先

屌你咩
人哋打5p字仲覆人
識唔識呢度規矩

我回覆有提醒樓主改下用詞
講得咁婉轉新會員點會明你咩意思
仲要咁林善教完人至「提」人改

下次我直接改明顯提醒字眼比果位當事人 
AMD Zen 4 可能用台積電5nm, 電晶體密度比7nm增加80%
今年 AMD 要推出的 Zen 2 架構 Ryzen 3000系列處理器將採用台積電7nm製程，而明年的 Zen 3 架構則會使用 EUV 的 7nm+ 製程，到了 Zen 4，AMD 就有可能使用台積電的5nm製程，畢竟上個月臺積電已經對外公開了5nm的細節，如果一切順利的話，AMD 有可能在2021年使用此製程生產 Zen 4 架構 的Ryzen 5000 系列處理器，如果進度不佳，台積電還有6nm製程給 AMD 選。
如果 AMD 使用台積電的5nm製程的話，電晶體密度會比現在的7nm製程提升80%，整體效能會提升15%，雖然台積電說明年上半年就能投產5nm，但是 AMD 已經確定使用7nm+ EUV 製程生產明年的 Zen 3 架構處理器了，7nm+製程可以讓電晶體密度提升20%而效能提升10%。
至於 Zen 4 是否會用台積電5nm製程，如果在2021年 AMD 就選用5nm的話，在對抗 Intel 的時候 AMD 就會有很大的製程優勢，畢竟根據 Intel 的線路圖屆時他們才開始全面轉向10nm，但是5nm製程是一個全新的節點，這意味著它不遵循7nm節點的設計規則，需要大量時間去設計晶片並進行實驗。
但如果從7nm轉向6nm製程就簡單得多了，雖然6nm和5nm聽起來差很小，但是6nm只是7nm的製程改進，設計方法與7nm製程完全相容，電晶體密度提升18%，和7nm+差不了多少（聽起來像7nm++）。
實際上 AMD 現在應該6nm和5nm的產品都在設計中，5nm的進度良好的話倒是就直接發5nm的，而6nm的是後補備用的方案。

Zen4 一定改 Socket
因為 AM4 用到 2020 （ Zen3 )

碌咗幾日 google
發覺 hynix cjr 兼容性仲好過 b-die

cjr die 果個價錢 對比 b die 來講 平左一大截
賣 g.skill royal ddr4-4400 8x2 
買左就算了
有冇ching 係用displayport
開機有時係冇畫面
但用hdmi 又有畫面
唔知點整過幾分鐘個dp 先會work 返

deal with it tomorrow
係咪 dp cable 有問題 ？

World’s fastest supercomputer will be built by AMD and Cray for US government
Frontier isn’t the only exascale computer the US is currently building either. Earlier this year, the Department of Energy announced a similar project: the supercomputer Aurora, which is being constructed by Intel and Cray at Argonne National Laboratory. Aurora will likely be the first exascale supercomputer in the US, but Frontier will have greater processing power.
These machines don’t necessarily mean the US is the world’s greater computing power, though. China is expected to have its own exascale supercomputer up and running by 2020 — a year ahead of America. China is also the world’s leader in terms of supercomputer volume, and is currently home to 227 of the world’s fastest computers (compared to just 109 operated by the US). Japan and the European Union are the other main contenders.
The news is a particularly big deal for AMD, says Patrick Moorhead, semiconductor analyst at Moor Insights & Strategy. The contract is worth $600 million and Frontier will use scores of AMD’s EPYC CPUs, each connected to four of the company’s Radeon Instinct GPUs.
The world of supercomputer chips is mostly in the hands of Intel, and AMD hasn’t supplied the processors for the world’s fastest supercomputer since 2012, when AMD Opteron CPUs were used to push ORNL’s Titan computer to a benchmark of 17.59 petaflops per second.
Moorhead told The Verge that the Department of Energy likely chose AMD for a number of reasons, including the performance of its processors, and its recent successes designing semi-custom silicon for Microsoft and Sony. “This bodes well for AMD’s future as this is technology that should be in the mainstream market after 2021,” said Moorhead.

一直用緊跟機嗰條
但今日換過另一條新線都係咁
次次都要用hdmi 通左畫面再轉dp 先得
唔知display 岀事 定咩
用緊evga 2070

我自己都用緊 dp 連接 vega 56 冇你遇到既問題
