猫の外部記憶: 5月 2015

※詳細の値段は購入時(2015年1月末)のものです。

まず省電力が第一と考えたのでCPUはTDP45Wで現時点最高スペックのCore i7 4790T一択。

36980

メモリは最大である8GBx4を載せてメモリ不足とはおさらば。
仮想PCも余裕を持って起動できる！！✌('ω'✌)三✌('ω')✌三(✌'ω')✌

ってわけで、安く済ませるためにまずは中古メモリを探してみたら以下のものを見つけた。

http://used.dospara.co.jp/sale/detail.php?serialno=83280000074606
12949x2=25898(+669)=26567

調べてみると相性問題が結構あるらしい。
( ˘⊖˘).。o○(これも相性問題で売られたのかな…？)
ってわけでやめて、価格最安で評価の良い以下のメモリに決定。

15400x2=30800

残りのパーツは、最初は以下のベアボーンで小さいのを組もうかと考えていた。

ケース+電源+マザーだけで33kはなかなかの値段…

なので、それぞれの同等以上のパーツを検討してみた。

6665(+1018)+4980(+398)+9100=20745(22161)

送料とか考えても圧倒的に安いのでベアボーン却下。

H97-PROは、メモリ最安がヨドバシだったのでそのポイントを使うため、ヨドバシで購入。

最初はまるまる1式買って組もうかと思ってたけど、電源とケースはほぼ同時に買ったファイルサーバー用のQ1900Mに使い、ケースと電源は余ってたものを使用。

ストレージはTranscendのSSD 512GBを購入。

これで色々遊べるPCが完成。

2015/07/23追記。
このPCで「World of Warships」が1080p、画質設定「中」の状態で20～30fpsって感じ。
別GPUを載せてなくても内蔵GPUでまぁ普通にプレイできる。

2015/11/10追記。
「GF-GTX750Ti-LE2GHD [PCIExp 2GB]」を購入。
「World of Warships」が1080p、画質設定「中」、OBSでGPUエンコさせながらTwitch配信を行っても60fps安定。
「高」以上の状態で配信するとたまにカクついた。

2016/01/07追記。
上記グラボで画質「最高」に設定しても、60fps安定してた。
LAN周りに異常があったからカクついていたようだ…。

調べたら以下の対策で解決できた。
1. 「./config/environment/development.rb」の内容を変更する。

Rails.application.configure do

↓

Your_Rails_Application_Folder_name::Application.configure do

Your_Rails_Application_Folder_nameは「first_app」なら「FirstApp」にするらしい。

上の対策だけだとまだエラーが出る。

        from bin/rails:4:in `<main>'

2.「./config/environment.rb」に以下を「Rails.application.initialize!」より上に追記する。

require 'tzinfo'

これで無事実行できた。
