Z370 Taichi and Intel Arc A770

Goin to put this card in my system. I have download and installed BIOS 4.20E which has support for Resizable Bar.
Intel docs say to do this for low idle power consumption.

For optimal power consumption, configure the BIOS?¯as follows:
Allow OS controlled ASPM by setting Native ASPM to Enabled.
Enable PCI Express root port ASPM and select L1 Substates.

Can someone tell me which settings in the BIOS corralate to these instructions?

Hi Len,

Did the BIOS update work with the A770 card? And where did you source the BIOS from please?

Thanks,

Andrew.
