こうして見ると、社外品ってネットワークとSSDとメモリ位じゃなかろうか？
3.hdparm -t /dev/nvme0n1
$ sudo hdparm -t /dev/nvme0n1
/dev/nvme0n1:
Timing buffered disk reads: 9874 MB in 3.00 seconds = 3290.69 MB/sec
ちょっと遅いかな？
4.memtest86+(？x86じゃ無いし)
L1&L2&L3がみな同じ速度って有りなのか？メインメモリーの速度もちょっと遅め。
全体的にカリカリチューンと言うより安定性を求めた高速性って感じ。
CPUも余力(クロックを押さえて省電力)が有るのでメモリー共々OCすればと夢想する次第。
