Guys,

Is there something I'm not seen here with my Maximus Extreme XIII and 10900k?

I know that 10900k has 16 lanes that are shared but this one I'm not comprehending .. I have Strix 3090 in top PCIe@16 , then I run my OS of Asus DIMM2 with 1 Samsung 970 Pro no other M.2's are occupied.

I also run external Asus wireless AX card in PCIe x1 and its working fine, but If put that Wi-Fi card in to the PCIe below which is x16 it doesn't work, it shows in device manager with red mark but it simply dosn't work, no internet available.

I have tried switching sharing option in Bios but no go. Why works in PCIe@4 but not PCIe@16 .
I have never had to deal with loss of lines, always had CPUs with 40 lines so I'm a bit lost here.

Thank you

So many views and no one knows, that is disappointing.

Have you tried Reinstalling the drivers for the card ???
ithe x4 Slot is connected to the chip-set while the x16 goes to the CPU
also in the bios set the lanes x8 + x8 or x8 + x4 + x4
in the last case there are two options one for using both onboard m.2 slots and one to enable only one and allow the x16 slot to run at x4

However I still think this is a driver issue as the card is connected over different lanes
I had similar issues in the past with some USB devices (it's rare but it does seem to happen)

Thank you very much for your response.

Yes I have tried reinstalling drivers # of times with no change, but I will tried again, maybe by miracle something will work. Also I did poke in the Bios to see If I could make some changes to make it work , but tbh. I have always used Asus WS boards and although Bios across Asus boards seem the same , this ROG has slightly more complicated layout so I might have to look into it some more.

I also left all M.2 slots unoccupied to avoid any issues with lines limitations due to 10900k, I run my OS of DIMM2 which seem to run nicely and its easy accessible, yet I'm dealing with this.

I am lost here. I have tried reinstalling drivers again with no change. Going to Bios I can see my GPU is running at @8 in first PCIeX16 and the wi-fi card shows to be in X1 mode in the lowest second PCIe X16, but nothing works. Why card works in PCIeX4 but not PCIeX16. I don't see anything in Bios I can change to make it work.

if it does automatically detect that there is a card in the second x16 slot the first slot will run at x8
this is pretty normal behavior since it shares the 16 GPU allocated lanes
The only thing I could think of now is that your wifi card might have problems with PCIe Gen 4 slots
However you can test this by forcing the CPU lanes to Gen 3
If you have a PCIe Gen 4 GPU this might reduce the performance of the GPU

it is also weird because the Card works in the x4 slot
but that slot is connected to the chipset and the chipset only uses PCIe Gen 3 ... I might think it might be some issue like that

Upon some testings and moving things around I think partly I got some clarification. You were right about drivers and it seems to be related to AX58BT card itself while is connected to PCIEX16_2, seems that for some reason there might be some compatibility issue.

I took one of my spare Asus AC68U wireless card X1 and installed in that PCIEX16_2, installed the drivers and boom, works great, on the other hand that doesn't work with AX card.

At least I'm glad its not the PCIe itself as I was slowly wondering about that, for now I can run that card of PCIEX4 . I have already sent them feedback form with all the details, so hopefully something good will come out of this.

Thank you for your help I appreciate that.

just posted this for somebody else

You can actually set the GEN per PCIe Slot
So you might want to try setting "PCIEX16_2" to Gen 3 to see if this solves the problem
if it does than we know that the card does not play well with Gen 4 slots (Might be useful for Asus to know so they can maybe fix this with a firmware update)

Thanks for you effort in trying to help me.

Yes I have tried to change to GEN 3 a while ago, but that didn't make any difference I was still unable to resolve the issue. I have sent Asus very detailed info in regards to this issue and the troubleshooting process I took to tried to resolve it and how I can replicated it. Also I did let them know that their AC68U Wi-Fi card works fine with any of the slots, so that should help them in the right direction to try and rectify this.

I've been told that they working on either drivers for PCE-AX58BT adapter or on Bios, so we will see how that goes.

Thanks again, much appreciated.

Its been 2 weeks, no updates yet, I'm wondering if Asus even working on the fix.
I will keep you posted

Its been almost 2 months, disappointment would be understatement with how Asus deals with this issue. Let me tell you how they have been interacting with me thus far.

I have troubleshooted this issue very extensively , every setting in BIOS and I have sent them all the info they have acquired from me, then I got first or second email telling me they are working on either Bios update or AX card driver to rectify the issue.

Here is the disturbing, almost disgusting part.... Ever since almost on weekly basis I have been getting their emails , getting me to try this or that and Its OK, but then telling me that I should send motherboard for RMA.

Then after I said AGAIN, how everything else works perfectly in PCIEX16 slots, but the AX cards alsone, so I got following email with apology that this is unacceptable and they will fix it and after reviewing my info is not the motherboard, yet , again they seem to copy and paste their generic response and saying "we will fix it and I should get this resolved soon.

Disgusting how they are playing games with people, after dishing out always for their best hardware they are doing this :(

To date, they have been doing the same generic emails and one is to send motherboard for RMA and then following email saying " after reviewing the info you sent us, there is no issue with motherboard, but with drivers of the AX card or Bios" but this never stops, Its like they just constantly copy/paste they generic responses.


When I got very first support email asking me to send the board for RMA and after I have responded that there is nothing wrong with board because I have tested my older Asus AC wireless card and after I have install the drivers both PCIEX16 slots are working perfectly fine, so Its the Asus AX wireless card drivers or Maximus Extreme XIII Bios needs further update to work with PCIEX16 slots. I have also tested other wireless cards and all working perfectly fine, so again, Its the AX cards drivers and they know it, but playing ignorance and are to lazy to give me a genuine meaningful response.

All those years, I have always thought of ASUS #1 and I have always got they server class hardware, but after this treatment, I am sinuously considering kicking Asus in a dust and never looking back, this is not the way you dealing with customers, let along long time loyal users and their supporter.
