なんだか、ツギハギに増設をしていたら気がついたら規格まちまちになってて、遅いものに足を引っ張られてるんじゃないかという気がしてきたので全部調べてみる。

こっちはすべてPC3L 12800Rでちゃんと1600出てる。
しかし見事にばっらばらだな。RANK1とRANK2の混在は問題ないんだろうか？

おや？こいつもmicronのPC3 10600Rなので1333 MT/sのはずだが、 と思ったらなんとHynixのPC3 8500Rのが混ざってる。こいつの遅さはこのメモリのせいか？外してしまおう。
と思ったが、結局全部10600だった。よくよく調べるとそもそもRX300 S7って2G PC3-10600Rは動作保証がないようだ。規格通りの速度が出ていないのはそのせいかも。
