Booted from a flash drive with a clean install of Windows 10 ˇX speeds are 943/897 ˇX so the network card is fine; something at the software level is throttling the speed.]]> Wed, 04 Nov 2026 19:20:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=113606&PID=202230&title=b450mhdv-r4-0-lan-speed-question#202230 https://forum.asrock.com/forum_posts.asp?TID=113606&PID=202229&title=b450mhdv-r4-0-lan-speed-question#202229 Author: nobana1

On PC 1, the download speed is 961 Mbps and the upload speed is 952 Mbps. PC 2 is equipped with a high-speed network adapter; the speed reaches 654 Mbps but stabilizes at that level (it does not go any higher).]]> Wed, 04 Nov 2026 19:01:19 +0000 https://forum.asrock.com/forum_posts.asp?TID=113606&PID=202229&title=b450mhdv-r4-0-lan-speed-question#202229 https://forum.asrock.com/forum_posts.asp?TID=113606&PID=202228&title=b450mhdv-r4-0-lan-speed-question#202228 Author: nobana1

I am not sure I understand what you are asking here. Incoming speeds from ISPs are
almost always much higher than outgoing. Internal LAN performance should be closer
when it comes to incoming and outgoing (between 2 local PCs on the same network).
If you have an issue with a local network then make sure you are using a proper
CAT6 ethernet cable not a CAT5. A CAT5e cable should also work fine as it tops out
at 1000mb/s, it should be printed on the cable itself. With CAT 5e however you
have no headroom and any damage on the cable or an overly long cable run will cause
the system to auto negotiate to 100mb/s.

Make sure your LAN adapter is set to "Auto negotiate" under it's Duplex settings.

Let me know if any of that helps.]]> Wed, 04 Nov 2026 18:33:24 +0000 https://forum.asrock.com/forum_posts.asp?TID=113606&PID=202225&title=b450mhdv-r4-0-lan-speed-question#202225 https://forum.asrock.com/forum_posts.asp?TID=113606&PID=202223&title=b450mhdv-r4-0-lan-speed-question#202223 Author: nobana1

GOOD DAY EVERYONE!!!

On the ASRock B450M-HDV R4.0 motherboard, the network card shows an outgoing speed that's almost 2 times lower than the incoming speed, but the speeds should be equal. The cable is fine. On one PC (configuration in the profile) it's 960 vs 940 Mb/s.

I have no idea what to do?!]]> Wed, 04 Nov 2026 18:05:50 +0000 https://forum.asrock.com/forum_posts.asp?TID=113606&PID=202223&title=b450mhdv-r4-0-lan-speed-question#202223
