12v電壓過高

已換牛都係咁 (問fd借舊牛)
係咪冇得救要換板?
有冇D setting可以降頻用住先?  (一換就要成組換.....)
有甚麼是用12v的? 如關掉過壓保護,會有咩影響? (例如邊D件易燒)

大感謝

會唔會有粒sensor之類在哪裡? 會唔會有機會多塵引致detect錯誤?
定係內部線路唔關事?

It's good for you have switched to another PSU for a trial!

This almost certify that a sensor fault on the motherboard but not over voltage happened.

1. To make yourself feel satisfy, get a multi-meter to make measurement on the 12V output but it is not necessary indeed!

2. I saw all the temperature & other 5V/3.3V are showing normal on your picture, just ignore this symptom since no power surge (protection) means it's working normal.

Bios 幾多volt? 部机正唔正常?

已經試了換牛,借人的舊牛試,都是同樣結果

Bios 幾多v? 你意思在 bios看的v數嗎?
跟用軟件睇一樣

跟據ATX規格,+12V最高係12.6V,假如超過,一般有牌子嘅火牛都已經會overvoltage而shutdown咗,亦唔會出Power Good訊號去開機,多數係塊底板個12V電壓ADC出咗問題而報錯數,最準係用數字他錶check voltage

用軟件睇未必準喎...

要知真正電壓係幾多
用他錶直接度先得

牛應該係ok呱,fd用開
如果係sencer就 ok
最怕係扯大咗電壓整燒其他件啫

off咗個over volt protection
用咗一陣好似ok暫時冇咩事
個數字有少少浮動

他錶...
我冇+重點唔識用

軟件check電壓唔準
