Question Asrock Z370 with RTX 3070 = No Fun.

Nov 18, 2022
Hello, hoping for an answer but almost going to give in.

No display coming from a Gigabyte RTX 3070 gaming OC, when using in a Asrock Z370 motherboard and I5 8600k

A GTX 1070 works fine in the Z370 board, as too does a RX 5700 XT. Just not the RTX 3070 when install in the Z370 board, so the motherboard pcie slot if good.

The RTX 3070 works fine when put into a MSI B450 Tomahawk motherboard and Ryzen 5 2600, so the card is good this is using the same display port cable / same monitor and same power supply.

Tricks I've read and tried are;

Change which pcie slot card is installed in.....didn't work.

The Z370 board bios has been updated to latest version as of yesterday.....didn't work.

Remove an M.2 drive and reset CMOS....didn't work.

Disable IGPU in bios....didn't work.

Force pcie slot to be in Gen3 mode......didn't work.

Is there anyone who may know of any obscure setting in the bios which may be causing this to solely affect the RTX 3070.

All components work, just not when the RTX 3070 is in the Z370 board.

Thanks for anything you chip in with.
