MSI MPG X870E Carbon Wifi Hard Stutters/Hiccups THIS NEEDS TO BE SEEN AND FIXED BY MSI

(video showcasing the terrible hiccups and stutters, running default BIOS with no EXPO or PBO, fresh CMOS reset)

Hi, it's been a month with this motherboard and I'm having a hard time fixing the stutters I have with my config 9800X3D / RTX 5090 Aorus Gigabyte Xtreme Watercooled / 32GB Corsair Vengeance 6000Mhz CL28 RAM / PSU Corsair RM1000X Platinum.

1. I've seen threads suggesting downgrading the LAN Realtek driver to the 10.72 or go with the 10.74 NDIS Not Support Power Savings and turn off all saving features. Didn't help and on top of stutters could still notice lag spikes or packet loss where the enemy lands shots I dont even see. I tried as well upgrading to latest driver released days ago 10.75 and still nothing. Tried as well the NetAdapterCX version of the driver and it's even worse, I get more pronounced hiccups and stutters.
2. Tried all sort of BIOS settings, disabling iGPU, SVM,. IOMMU and all unnecesary options and features that I'm not using, tweaking RAM manually without enbaling EXPO to the point where I spent days testing stability with AIDA64, Y-cruncher, TestMem5 Ryzen3D and 1usmus configs. Set a proper PBO CO of -25/20/15 (kept lowering it even if it was stable just because I was being paranoid) with no boost clock, or scalar override. Tried to run the PC on default settings with a CMOS reset, then only EXPO enabled. Absolutely nothing changed and stutters still occured.
3. Turning off all saving features from LAN ports, Wifi and BT, as I said above I even tried turning off the 5G Lan port, Wifi an BT to test and still experienced stutters, less pronounced but they still happen every 2 or 3 minutes instead of every 5-10 seconds. Tried switching to the 2.5G as lot of people suggested that's better and more reliable than the 5G but it's the same for me sadly.
4. Turning off all power monitoring options in RTSS, or Nvidia overlay. Even uninstalled RTSS, and Nvidia app, didn't help a bit.
5. Reinstalled Windows several times, wiped SSD with the cleanup option in BIOS.

I'm on latest BIOS, latest chipset from AMD, Nvidia, Wifi, BT, and other devices that requite any drivers. (I downgraded from the Nvidia hotfix just to try something for Clair Obscur but stayed on 576.52 and proceeded to record since it doesn't affect anything at all).

What I've tried so far:

1. 1. I've seen threads here suggesting downgrading the LAN Realtek driver to the 10.72 or go with the 10.74 NDIS Not Support Power Savings and turn off all saving features. Didn't help and on top of stutters could still notice lag spikes or packet loss where the enemy lands shots I dont even see.

I'm literally lost, I know for sure it's the LAN, Wifi and BT causing the issues because of the design of the board and probably the CPU hogs resources from the LAN ports causing this massive unbearable hiccups and stutters, but no matter what I try the stutters and hiccups won't go away. Has anyone been able to found a fix without having to disable features I paid for??? Is MSI gonna ever adress this??? This is unreal, it's a premium board, how is this allowed??

I saw somewhere on this forum that for LAN, wi-fi and BT to work properly you need to have connected the optional PCIE_PWR1 connector on the bottom of the board too.
I haven't dealt with it myself. I don't use wi-fi or BT on my desktop, and I don't have any network device on my home network that uses 5Gbit speed. So I don't even know if the installed network card can handle the claimed speed

Plugged it and stutters and hiccups were literally the same.

Yeah that's why I sent mine back and got the better Tomahawk instead. Doesn't look as nice, but it allows two gen 5 drives simultaneously which even the Carbon cannot do, only other motherboard that does is the Godlike.

As soon as support stops making me lose time and hand me the money back for this piece of crap, I'll go and buy the equivalent in other manufacturer because this is unbearable. This is the last time im buying mobos from MSI

return and get a new board. probably just a defective board. it happens. if you have a separate pcie nic, you can try disabling the onboard lan and use that. it will tell you if that's your problem. it might just be a bad network adapter, so return the board and get another one.
