Slow boot and no USB ports about gigabyte-z590i-vision-d-11900k

[SchmockLord]

Try the newest release. I have much better experience with this one.

I got XMP enabled (DDR4-3200-16-20-20-1.35V) on my HYPERX Fury 3200mHz CL16.
Everything works like a charm.

Note: I can boot Ubuntu from live USB and all works fine. So the hardware setup seems ok.

Ok, so I did get USB port mapping this time. But boot is still painfully slow and it kernel panics shortly after the desktop is loaded.

Note that I still have the onboard WiFi / Bluetooth module connected. But I'm using a Broadcom chip from my previous hack (connected via M.2 on rear of the board). The few times it has booted this is working. So don't think this could be a problem?

Try to not enable XMP. I also have issues with it on and noticed, that sometimes the BIOS needs a reset: Unplug power. Load optimized defaults and then just (without BIOS adjustments) try to boot into macOS again.

Thanks! Disabling XMP seems to have fixed the kernel panics 🤞 On my Z390 board this had to be enabled to boot macOS. So I am cautiously optimistic now and very much appreciate the help 😄

You might set your RAM speed to 2667Mhz because I know that this is supported by macOS. But I have experienced the same issues like you when I used RAM speeds like 3600Mhz.

[nhojb]

I tried setting speed to DDR4-2666, but this is also unstable (not as bad as enabling XMP, but still fails after a few minutes). So I'm stuck on 2133 MHz - but at least it is stable. My memory is rated at 2666 MHz. Not sure if faster RAM would improve stability at 2666?

[nhojb]

It turns out the board is quite picky about memory: https://www.gigabyte.com/Motherboard/Z590I-VISION-D-rev-10/support#support-doc

Mine is only rated for 2133 MHz, so time for an upgrade - I'll have a look at the HYPERX Fury.

In the meantime completely disable XMP and ram tuning.
If you need, this is my 32GB kit P/N: HX432C16FB4K2/32

[SchmockLord]

Mine is G.Skill 3600Mhz CL18. F4-3600C18Q-128GVK. Native according to the table 2667.

I tried XMP with 3600 and 2667. Both cause instabilities. But only in macOS. Windows is fine with 3600Mhz.

Only with 2133 I have no issues.

Ended up getting KLEVV BOLT X 32GB Kit, 3600 MHz, DDR4, XMP 2.0. It's listed as compatible with XMP in the Vision D support doc.

Has been working a treat so far with XMP enabled @ 3600 Mhz. Seems rock solid.

The slow boot issue disappeared when I switched to a WD_BLACK SN850 SSD (PCIe 4). Not sure what was the issue with the Samsung 970 EVO Plus - possibly because it is PCIe 3 or perhaps the SSD firmware needs updating. Anyway the WD drive is very fast so no complaints there.

In case anyone else finds this thread while searching the Internet for "Z590 slow boot".

So the BIOS on my Vision D was incredibly slow to boot, 30-40s before loading the bootloader (GRUB in my case). It was even slower resuming from suspend: about 1 minute! "Fast Boot" did not help.

Most of the time, a slow BIOS is due to scanning buses and other peripherals.

After a few hours of trial and error I got it down to ~10s by disabling:

• All the SATA ports not in use
• Thunderbolt
• USB "legacy" and everything else with "legacy" in the name (mouse and keyboard still work)

Slightly off-topic sorry.
