3000円と安価で、DDR3-1600、CL9、1.5Vで動く優秀なメモリです。
全品出荷前検査のはずのシリコンパワーのメモリですが、1枚がMEMTEST86+で開始直後からエラーを出し続けました。
初期不良という事で交換して頂きました。しかし、交換品も同じ緑基板のメモリで、MEMTEST2時間ほどで大量のエラーを出し、2枚とも不良。
メーカーにも問い合わせつつ、もう一度交換してみようという事で、再交換して到着した品が写真下側の青基板のメモリです。
青基板のメモリは不良なく2枚とも正常でした。
違いとしては、まず、バーコードや型番は同じですが、製造番号?が違っています。
基板自体は(緑)W1107 94V-0 E77755→(青)NYKS NM10 94V-0 1140 24
20YT5NGのチップの製造週が、(緑)1201→(青)1201Hへと変わっています。
他にもチップ左下の●が大きくなっており、その右側の文字列が全く違うものになっています。
私の経験からの主観になりますが、緑基板には不良が多く、ロット不良ように感じました。
以下長々とSPDとXMPのデータです。
しかし、どうにも正しいとは思えない値が出るので、CPU-ZはXMPの値を、HWinfo32はSPDの値を見ると良いと思います。

初期不良掴みたくないですから><

初期不良は問題の切り分け等、後処理が面倒なので当たりたくないんですが、ここ最近良く当たって困りますねー。
