No gpu output when trying to use middle Pice 16x slot

[Novajetfire333]

Trying to move my gpu down from top slot to the middle one.... but when i move down to middle the pc boots fine acording the the indicators on the motherboard but i get no input on hdmi.

if i move back up to the top slot it works fine. i tryed restting cmos and looking in bios i didnt see an option to change the the gpu to the middle slot or anything like that Help Please!!!!!!

specs?

 

lots of boards will only use the top slot for the gpu, as that is the optimal slot

Just run the gpu in the top slot, its the only one that is x16, and will give a small boost to performance.

oh and i was incorrect the green qled light was on so im having a boot problem

that being said the white gpu q led passed with is weird from what im reading if it was a gpu boot issue both the white and green qled would be lit

The motherboard PCI-E X16 slots configuration is either this (excluding bottom X16 slot because it is coming from the X470 motherboard chipset) :

• Top X16 + middle X0
• Top X8 + middle X8

What type / model Ryzen CPU are you using?

 

In the BIOS, under the Advanced tab, do you see a PCIEX16_2 Bandwidth option?

If there is (DEPENDS on the CPU you have), options should be [X8 Mode] and [PCIe RAID Mode]

 

What I said above, but your motherboard *might* not allow the top slot to be empty, from referring to the motherboard manual.

Page 1-7.

If you have a Ryzen 2400G, then yes, you only have PCI-E X8 to begin with.

It will be only a X8 top + X0 middle option (again, excluding the third X4 slot).
