Question 9800x3d + 4070 Super Ti - MSI MPG X870E Carbon Wi-fi - Ethernet dc's

[Spartagus423]

So I randomly updated my Computers Mobo/Video Card/RAM and so I did a fresh install of Windows 10 Pro x64 and did all the windows updates and also Updated the ethernet/wifi/chipset for my new 9800x3d and also I updated to latest Bios 1.A23. I updated to latest Video Drivers.

Also I am coming from i9 9900Ks and the boot times feels so much longer on this new build.

Video Card - Asus Rog Strix Gaming OC GeForce RTX 4070 Ti Super
Mobo - MSI MPG X870E CARBON WIFI
CPU - AMD Ryzen 7 9800X3D 4.7 GHz


Here is my PC Build Parts
PC Part Jan 23 2025

So I loaded up discord to stream a movie with my friends at 1440p... While I was gaming with Path of exile on my second monitor Unlimited frames in game to test out my New CPU and within Five minutes I noticed my internet connection would disconnect then reconnect so I decided to lower my streaming from 1440p to 1080p to see if that helped which I think it did.

Even when I wasn't streaming I feel like my Ethernet would randomly D/C and Reconnect here and there and I am using the 2.5 GHZ slot because for some reason the 5Ghz doesn't seem to work. I am very new to building PC's I built my first one Five years ago and everything went pretty well but I had my video card die and so I replaced it and I wanted to update to this new chip.

I guess long story short why would my ethernet D/c & Reconnect while streaming or gaming with no frame cap? I don't know how to make sure my PC is running optimally so just looking for advice or guidance. So far today is my first day I haven't really had any issues and last night when I lowered streaming from 1440p to 1080 it seemed to fix the issue. I feel like I am doing everything right but I am still messing with settings. This is my First AMD I ever owned.

I did a PC Benchmark below and it says it is running below optimal but I am also running a game and x2 Streams 720p in backround.

UserBenchmarks: Game 94%, Desk 109%, Work 100%
CPU: AMD Ryzen 7 9800X3D - 106.6%

I did a fresh install of Windows 10 Pro x64
After recreating your bootable USB installer for the OS, then installing the OS in offline mode? On a side note, you're advised to install Windows 11 as Widows 10 will be a decade old towards the end of this year.

Also I am coming from i9 9900Ks and the boot times feels so much longer on this new build.
This was mentioned after AM5's launch. So with AM5, comes with the territory though there were BIOS updates that helped make the boot process faster.

I updated to latest Bios 1.A23.
Did you clear the CMOS after verifying your BIOS was successfully flashed to the latest?

I updated to latest Video Drivers.
Using DDU in Safe Mode prior to manually installing the latest driver sourced from Nvidia's support site in an elevated command?

I did the CMOS after updating no change.

I didn't need to use DDU uninstaller for video drivers because I did a fresh install of Windows and just updated with latest Nvidia Driver

There are known problems with both Intel and Realtek's 2.5Gbit Ethernet chipsets and drivers, leading to intermittent connection problems.

You may not notice short duration interruptions during web browsing, but certain continuous operations may be affected as you've discovered.

I see your motherboard uses Realtek 8125 and 8126 chipsets.

1x Realtek® 8126 5G LAN
1x Realtek® 8125 2.5G LAN

You may find that downloading the latest drivers from the Realtek website fixes the problem, or not! Make sure you update both ports. Don't be surprised if the problems persist.

Have a good dig around the forums for solutions to Realtek 8125/8126 chipset problems.

If you cannot get either port working properly (2.5G or 5G) you might consider buying a 1Gbit/s PCIe Ethernet card. Older technology but often more stable.

People who need reliable network connections on home firewalls (pfSense) or servers often pick specific Intel chipsets.

FreeNAS 1GbE NIC Top Picks​

1GbE NICs in the FreeBSD world generally see Intel as the top choice. The pfSense team also sells Intel based cards and systems with embedded Intel NICs.

1. Intel i350 (and Intel i354)
2. Intel i210 / Intel i211
3. Intel 82574L

The Intel i350 (e.g. Intel i350-t4 network card) is a high-end 1GbE controller capable of servicing up to four ports. The Intel i354 is an embedded NIC for the Intel Atom C2000 series (Avoton and Rangeley.) The Intel i210/ i211 are lower end current generation 1GbE NICs from Intel that are used to control single 1GbE ports. The Intel 82574L is the single port NIC that the i210 replaced. Given current pricing, we recommend sticking to the Intel i350 or Intel i210 NICs.

The reasonably priced card below on Amazon uses an Intel 82574L chipset, which is 3rd choice in the list above. An Intel i350 card will be considerably more expensive and overkill with multiple ports. I'd probably huy an i210 card. Check second hand prices for server "pulls" on eBay.

I've seen dropouts on my 10Gigabit/second Ethernet cards and gone through a number of drivers over the years. I'm slowly moving over to 10Gbps SFP+ fibre optic cards instead of 10Gbps Ethernet. No point doing this in your system, but it shows you're not the only one experiencing glitches.

Check your Ethernet cable and try another one. Bad (tarnished or dirty) contacts have been known to cause dropouts.
