Yes, use your bios and replace the ME with version 11.7

I will try the alternative that you indicate and I will let you know. Thank you very much for all the help given

Yes, now I will try and I will be notifying news by this means. Thank you very much for the help

UPDATE:

I made progress a bit, but got stuck again :frowning:

Hello @Kuri0

@Orion still has a problem with setting a bar larger than 1GB

Large Memory seems to be a thing, so Above 4g decode is ok?

If a value above 1GB is set, then the board fails to POST.

Here are some screen grabs of Device Manager.

@Kuri0 Any idea why I can’t find "“M1LEN” ( DSDTMod.dsl)??? :confused:

247

Hello @Kuri0,

Patches were applied, however, the only one that worked was “PciBus | Remove <64GB BAR size limit (Skylake/Kaby Lake/Coffee Lake)”.

I’m not sure where to go from here.

Many thanks for the reply,

M1LN, not M1LEN. This is the misspell.

Hello @Kuri0 ,

Many were tried. 8GB and 16GB and unlimited were tried. Arc A770 16GB card

Does the Intel ME version matter?

11.8.50.3425 is in the file at the moment.

Many thanks,

@68k-dude I don’t think ME is related. Does it boot with HDMI connected to motherboard ?

Hello Kuri0,

I don’t want to spam post all over the forum. Apologies.

Orion is having problems posting here. I’m helping via Discord.

I believe the onboard video was tried.

I will confirm and get back to you.

Here is a screenshot of the error Orion is getting. It looks like a browser issue.

Although, there is something strange, I had inserted the UEFI PATCH, but I still have the limit of only 1gb (resizable bar max 1gb, everything above that fails)

so, have you tried my bios with your ME, with my dsdt?

258

If right. That worked to activate the 4g decode :clap:

bios with 4g decode ON + rebar (max 1gb) asrock z170m formula

seems like you use your own bios, the one i gave to you had the latest mcode update, latest efi, orom and gop vbt, and came from a clean bios (everything was cleanly updated), i wonder if you use my bios but replace it with ME 11.7.0.1xxx (like what you did before) + replace the dsdt, would work on setting the rebar size above 1gb.

Unfortunately, same result. It does not allow more than 1gb rebar (4g decode ON with dsdt).

Could you help me to validate if my UEFI Patch is correct or not? (coffelake-9900k)

ps: I tried to keep the bios as main, but it is unstable with my overclock. I went back to my modified bios (attached in my current msg).
