Ok so i spent great amount of time trying to figure out what the issue is and i found it.
The issue is that engineers at Asus smoke wrong kind of vape.
I had this plugged into the PCIE X16_2. Even without actual riser or USB cable.
So you would think that just the adapter wont do anything and thats exactly what i thought but it DOES.
I do have another adapter similar to this that simply changes the angle to do vertical mount for a capture card and i had capture card unplugged from the riser but GPU remained at X8
That was until i removed the angle ribon adapter from the PCIE slot GPU turned into X16.
So what in the world ?
If CPU has 24 lanes, why does X1 PCIE adapter takes away 8 lanes ?
Also why does 2nd PCIE X16_2 runs GPU at X8 and not at X16 as it claims to be ?
Look, i understand that i made a fool of my self thinking that an angle adapter is simply extension of the wires and having it plugged in would not effect the circuit in any way, but to my SHOCKING surprize it did.
Either way, this is some "we were high" design choices. There has got to be a way to fix this BS.
Just look how many people are having issues with that its insane.
Not only that, but during my testing i also found that this board does not like to have 5 SATA devices if 5th one is DVD ROM.
You can have 6 SSDs or 5SSD no problem. You can have 3SSDs and 1 DVD ROM but as soon as you bring one more SATA device, post gets stuck in A2 trying to detect things.
This is balls.
Why does it detect each SATA device by its self just fine but only when number exceeds 5 and only when CD ROM is present it does this BS.
No please be very very specific here.
I did not use the riser, i just had it plugged in without anything being plugged into it on the other end.
So theoretically, none of the connections would have been effected at all since the other end of the riser is open line..
I took that idea and i plugged in just the adapter with nothing plugged into it thinking that it would be open line before and after the adapter.
For some weird reasons it wasnt.
My guess they do a hotplug detection regardless of data lines used or not used and simply take 8 lanes away.
This is insanity. CPU has all those lanes just hanging and not used.
There has to be a solution to this. This is a joke considering the cost of these boards is astronomical to some.
Also i am sick and tired of this forum capcha bug
Hi @tonycstech,
I think it's fairly transparent, as per the manual. The motherboard firmware doesn’t distinguish between active devices and passive adapters when reallocating lanes; it will simply detect that the slot is in use. This will very likely be the same regardless of SKU vendor.
