Question Does ROG STRIX B450-F Gaming II MB have a default PCIE slot for GPU?

[DavidFahey]

Hi, my son & I are building a computer using a ROG STRIX B450-F Gaming II motherboard and tried to install the GPU (Zotac Nvidia GEFORCE RTX 3070 Ti) but when we power up the system, the monitor says "no signal" on the HDMI port....Does the motherboard have a "default" PCIE slot that the GPU has to be installed in? Have tried swapping the HDMI cable but that didn't work....Thank you!

Please list your full system specs. And just to check, are you plugging the HDMI cable into the GPU and not the motherboard?

Yes, we are plugging HDMI cable into the GPU, not the motherboard.

As the Athlon has integrated graphics, have you tried plugging the HDMI into the motherboard to see if you can at least get into BIOS? There maybe a setting in the motherboards BIOS where you need to switch from integrated graphics to support a GPU? Please check your motherboards manual. I have to say though, I feel you need a stronger CPU in order to fully utilise your 3070 ti.

I'm not sure about your problem but that CPU will barely take advantage of that GPU. You really should upgrade to a ryzen 5 5500 at the minimum.
