Review: 曲げてしまいました． 古い経験では，CPU側にピンがあり，ピンの間隔もそれなりにあったので，ピンが曲がっても直すことができました．この機種（LGA 2066）ぐらいになると，直せないです． それで，元のマザーと単純に置き換えることが確実にできる，という主旨で，現行機種ではなくやや古い機種ではありますが，何とかこちらで見つけて，購入．ちょっと値段が高かったと思いますが，単純置き換え，を優先しました． ところで，ASUSのマザーの場合，付属DVDからドライバを入れなければなりませんね．グラボなど拡張カードの場合は，ハードウェア付属のCDやDVDは古いので使うことはない，と経験上，思っています．しかし，ASUSのマザーの場合，ASUSサイトに掲載されているドライバはあくまでアップデートだけであって，まずは付属DVDを使ってね，ということのようです．

The CPU pins were all fine, all components working so far after a couple weeks of use. Instructions were pretty clear on the setup. I have some experience building PCs but by no means an expert, everything was pretty standard.
