Gigabyte Z97X Discussion, Help, and Owners Club(SOC and Gaming Editions also included)

I'm having some ethernet performance issues with my Z97X Gaming 5 Windows 8.1 pro and was wondering if there is a setting that I've overlooked with the network driver or config that is harming performance of this system.

ISP is Comcast with advertised 200Gb speeds.

via speedtest, I get varying speeds.usually in the 145-150Gb range, occasionally as low as 40Gb and sometimes around 100 Gb

A macbook pro, on the same network/same router over wireless N 5 Ghz, scores 220Gb+ consistently.
Another desktop on the wired network gets 230+ Gb consistently.

config:
Killer E2200 GigE Controller
Driver: Rivet Networks
Date: 1/26/2016
Version: 9.0.0.37
driver is exws8x64.sys
Provider: Qualcom
Version 9.0.0.37

Items Disabled:
power saving - allow computer to turn off device.
Killer Bandwidth control
QosPacket scheduler, on or off makes no difference.
ipv6 is disabled

Enabled is WakeOnLan.

The system is setup Static IP, directly connected to a Gig E port on an Asus N66 WiFi router, and it is showing Gig E speeds on both the windoze side and on the Asus Mgt side.

Running Merlin if it matters, and do not have QoS enabled on the router.

The N66 is my backup router, and I get the same results with an Asus AC68u/r

Any ideas or suggestions are appreciated.

I rarely cross post to other forums and also rarely quote and reply my own posts, but I thought this thread is worthwhile.

Here is a small guide on how to get Windows to see your Killer E2200 NIC as a Qualcomm Atheros AR8161 PCI-E Gigabit Ethernet Controller....

the Killer E2200 NIC is actually more or less a Qualcomm Atheros AR8161 chip.

Think that qualifies as a necro and since search tool is broken (does not show any results, despite typing word I found 20 times on a same page)...


I have a Z97X-Gaming 5 paired with 5775c, is there a way to push BCLK past 101MHz? Straps doesn't work at all, it just doesn't boot.

I have 13 months of warranty left on my Z97X-Gaming G1 WIFI BK. My Lenovo laptop has recent BIOS updates to handle the exploits that require new firmware. When the hell is Gigabyte going to honor their Black Edition warranty and push out these patches from Intel?
