what bios for fx9590/chvf-z?

I'm getting my 9590 Saturday to replace my late and lamented 8350, it's turning winter and I have to keep warm some how.........

I have always run very early bios and they have served me very well but, as you know for the 9xxx cpus we have to run much later bios.
I have another 8350 in the chvf-z with 220... whatever bios and it's playing old scratch with my leg.........
when booting at anything other than default setting I get dr dbug code 5d if I don't get that I get no keyboard detected.
yes, I use a kvm.
yes, the rig is hanging on the wall.
yes, I know the Tt core p5 is terrible for cooling and the rad exhaust is flat against the wall.
I am going to run it this way anyway.
what bios are you using with your 9xxx chip?
yes, I am running windblows 10.

I run 1403 for all processors.

You are on the release bios. lol
You most definitely need to move up a little.

I have just flashed it to 1403, I can at least get it to boot with it.
I'll piddle with this one a bit before I tear everything out and prettify it for it's new processor.

I ran a 9590 on it with no problem. You'll be fine.
