its normal 1) its running in PCIE gen2 x2 mode (10Gbit max) 2) u also have higher latencies due to pcie controller which sits on chipset and not in cpu which also reduces speed by a bit u can try to overclock pcie bus or amd hypertransport, that could help

Buy PCIe x4 M.2 card adapter. You will double the speed to 20 Gbit/max. Here is my old posts: http://forum.asrock.com/forum_posts.asp?TID=738&PN=5&title=asrock-990-fx-killer-with-samsung-sm951 |
