rt68cx21x64sta.inf = Not Support Power Saving
Power Saving Mode = Disabled
Rcv Segment Coalescing IPv4 = Enabled
Rcv Segment Coalescing IPv6 = Enabled

rt68cx21x64.inf = Support Power Saving
Power Saving Mode = Enabled
Rcv Segment Coalescing IPv4 = Disabled
Rcv Segment Coalescing IPv6 = Disabled

at least on my adapter.
NetAdapterCX still doesn't support Receive Side Scaling on realtek.

What is best? With or without power saving? What is Receive Side Scaling? Does this affects performance?

Power saving typically means that you will save ~2W per day, but you will loose some performance and reliability.

{rtots640x64sta.inf driver for old Realtek LAN adapters updated from 10.66 to 10.68 with the Sept. 2023 release}

note - I sometimes go for the "not support power saving" version since I use an old PC with an old Realtek LAN adapter and to avoid certain power management problems with the lan adapter

I am not sure you can find drivers for RTL8125B by searching in Realtek's site. Try searching Google for RTL8125B, it might give you a direct link to Realtek's site.

Realtek PCIe FE / GBE / 2.5G / 5G Ethernet Family Controller Software - REALTEK

www.realtek.com www.realtek.com
Click to expand...

the latest Realtek PCIe LAN drivers from the Realtek web site should work for RTL8125B as it does say "RTL8125 / RTL8125B(G)" (meaning for both RTL8125B & RTL8125BG); I no longer "hotlink" or link directly to their recent drivers (the recent March 2024 releases) since Realtek no longer allows them.

My motherboard manufacturer just posted these to their support page. But when I run setup.exe, it won't let me modify the installation? Just reinstall or remove. I'm on 1125.10.720.2022 right now.

latest drivers should update to version 1125.16.1123.2023
