ADATA XPG CoreReactor650Gold

Posted by on 2021/08/01 No comments

上次寫了一篇 Cooler Master V650 V2 MPY-650V-AGBAG ，結果沒一個月就回修，這次再寫一篇，看會不會狗屎運再回修一次。

本來之前一年我的 2080 就很不穩定了，主要的問題是跑 Star Craft II 常常一開始遊戲就當機，或是跑 AI model training 就會當，我本來以為是 driver 或是我什麼東西沒裝好，跑了很多時間重灌但是還是一樣。
但是因為想換 Power 很麻煩，我就先在其他電腦跑 model training 所以一直沒有處理它。疫情發生之前還是有想到將 Cooler Master V650 拿回來做備品，準備交叉測試一下。
附帶一提，修電腦都要花很多心力在這邊，如果你有好人電腦維修工，記得要多獎勵他們

果然二星期前的某一天早上舊的 Power 在使用電腦到一就掛了，再也不能動了，舊的 Power 是 Seed L12 500W，這個只有最基本的 80 PLUS ，應該也用了超過十年，而且我這台電腦幾乎天天開機，也算夠本了。
看了很多網友都講 ADATA XPG 好，剛好 momo 有特價，所以就買來試試

Intel Coffee Lake Ubuntu Linux 速度太慢

Posted by on 2021/04/15 No comments

這個也是怪自己，最近因為 Windows VM 不知道為什麼速度變很慢，所以改用 Linux 跑 VM ，雖然 Linux 下 VM 速度比 Windows 快，但是整體的感覺還是慢．本來以為是我的 i5-9600k VM 表現不好，但是看著 CPU utilization 感覺還是怪

[Gentoo][ARM64] Compile qtwebengine fail

Posted by on 2021/03/23 No comments

If CPU number is too much, compile qtwebengine will fail, seems ninja compile issues.

it better to reduce CPU number under 8, batter number is 4 or 6.

just put MAKEOPTS=”-j 4″ on your /etc/portage/make.conf

It can be roll back after compile qtwebengine.

modify package.env can support special MAKEOPTS command on some packages.
ex:

echo "dev-qt/qtwebengine lowcpu.conf" | sudo tee -a /etc/portage/package.env
mkdir -p /etc/portage/env
echo "MAKEOPTS=\"-j4\"" | sudo tee /etc/portage/env/lowcpu.conf

htop more column for mass CPUs

Posted by on 2021/03/22 No comments

htop can support multiple columns in one screen, just press F2 enter setup mode, and change left column and right column to CPUs (1-4/8) [Bar] and CPUs (5-8/8) [Bar]

htoprc , put it on /etc/htoprc or ~/.config/htop/htoprc

# Beware! This file is rewritten by htop when settings are changed in the interface.
# The parser is also very primitive, and not human-friendly.
