找出根本原因的建議方法是什麼?如何啟用更多日誌記錄,或者日誌是否已存在,我在哪裡可以找到它們等。謝謝!
答案1
這不是技術上一個答案,但是…
這則ECC error or L2 poison was detected on a data cache read by a load
訊息指出記憶體問題,可能是 RAM 本身的問題,也可能是 CPU 上快取的問題。兩者都不是很好,但您可以通過以下過程測試系統 RAM:
- 重新啟動您的系統
- 按住該Shift鍵調出 GRUB 選單
- 選擇“Ubuntu,memtest86+”並按Enter
記憶體測試將運行直到時間結束或直到您按下該Esc鍵。讓機器在逃脫之前至少完成一項測試。
基於報告 大約在網路上,這個問題似乎只出現在高階 AMD Ryzen 處理器上。通讀這條長線AMD 社群網站上透露了這有趣的內容:
我更換了內存,幾天來電腦一直堅如磐石。希望這可以幫助你,就像它幫助我一樣。以前的記憶體是 Gskill 3600mhz 記憶體...新記憶體是 Corsair 的 3200 記憶體。
您的問題沒有說明您安裝了哪種內存,但如果它是一組頻率較高的模組,則 RAM 和 CPU 之間可能存在某些問題,導致不穩定。如果記憶體測試失敗,而您碰巧有一些可用的相容 3200MHz RAM(即使只是一個 DIMM),請考慮將其更換並再次執行記憶體測試。
答案2
BIOS
華擎 X570 太極
BIOS 的目前版本為 P4.30。
記憶
G Skill Trident Z Neo DDR4 - 3600Mhz 32GB (2 x 16GB),產品:F4-3600C16-16GTZNC
AMD 銳龍 9 5900X 12 核心處理器
Ryzen 處理器對 RAM 非常挑剔。
這些 DIMM 不會出現在記憶體支援清單中,如圖所示這裡。
memtest
通過了所有測試。
當我們觀察時,sudo lshw -C memory
我們發現 DIMM可能安裝到不正確的插槽位置。當使用 2 個相同大小的 DIMM 時,應將它們安裝到插槽 A2 和 B2 中。這是電路板佈局和記憶體插槽的圖像......取自用戶手冊:這裡...所以只需驗證這一點...
答案3
根據@heynnema的建議,我發現我的電腦上安裝的DIMM型號並未列在其相容性清單中。以下是遵循的步驟:
- 存取 CPU 支援列表華擎 x570 Taichi 網站。找出核心類型。就我而言是
Vermeer
- 透過運行找出系統上安裝的 DIMM 的型號
sudo lshw -C memory
(它是F4-3600C16-16GTZNC
) - 導航至記憶體支援列表對於 Vermeer,看看它是否受支援。不幸的是它不在列表中!也許這就是不一致崩潰的原因。我將嘗試受支援的 DIMM 版本,看看是否再次發生崩潰,並相應地更新此答案。
