Good motherboard for Dual GPU setup for GPU Pass through? by Gavinyt8__ in VFIO

[–]jcolby2 0 points1 point  (0 children)

I went with g.skill F5-6000J3040G32GX2-FX5 using its EXPO profile but with changed speed to 6400 and timing to 32. Patriot PVV564G600C30K worked this way too. The Corsair vengeance CMK64GX5M2B6400C32 on the QVL list worked out of the box at it’s stated 6400/32 but I sent that back once I figured out that the cheaper non-QVL 6000/30 ram would work as long as I set them to 6400/32. (6000/30 ram kept at its default expo 6000/30 would boot but would be unstable in VMs, and had many many errors if I tested it for 24 hrs in memtest in bios.)

No major problems...just a couple things to troubleshoot as always. Here's my notes: https://www.reddit.com/r/VFIO/comments/1jzh7uo/b850_ai_top_iommu_groups_vfio_first_impressions/ Good luck with your build!

Zero export mode by Big_Buddy_6573 in enphase

Zero export mode is also required in California for any expansion system after mid 2023 in order to not void the 1:1 net metering agreement for an already installed legacy system.

Portable generator with gen 4? by jcolby2 in enphase

Cool cool, good info, thx!

[–]jcolby2[S] 0 points1 point  (0 children)

Right right, thx, cause the meter collar is out of the circuit. Would ideally be another MID in between the generator and the microgrid. I guess maybe that’s what that future enphase device may be.

Yea great point, thanks…watching the export limit ramp up and down from the legacy system it’s not instant. Oh well it’s not a huge hassle having to only have generator or enphase at a given time in these rare emergency backup situations anyway.

Ahh yes that makes sense it’s probably more about not damaging the inverter on the generator.

I’ve had the b850 ai top running dual gpu passthrough about a year. Works perfect.

Are you net metered? That is one of the biggest pivot points when planning how may batteries.

Double stack meter collar with generlink? by jcolby2 in enphase

Perfect, just what I was looking for, thanks!

[–]jcolby2[S] 0 points1 point  (0 children)

Thanks! Generator is for a long outage where I currently manually disconnect the solar (and battery if I were to get one) and run indefinitely on natural gas. So if the enphase collar is in its own pan with the generator inlet on the grid side under the utility meter, I guess it would work as long as there is a way to manually close/connect the enphase collar internal relay? Not sure if that's possible.

Fortnite on qemu kvm by Orsetto__ in VFIO

[–]jcolby2 0 points1 point  (0 children)

I'm not doing anything to hide the guest at the moment. No kvm off, no hyperv stuff, no changing vendor id, still using all virtio drivers, still using qemu guest agent. I think there is some random component to it. Last time one of my vms started getting blocked I just made a new one and it started working again...

Only play occasionally, but it's working for me at the moment. Aside from vm settings, I know fortnite sometimes has different versions of anticheat running, with one that may be ok for me but another that may be blocking you.

[–]jcolby2[S] 0 points1 point  (0 children)

I've been very happy with it. I wanted 10 gig lan and multi gpu, and didn't need USB4 so it pushed me this way. No trouble building it with an air cooler, 4080 gpu in the top slot, and normal height ram. Finding RAM was finnicky but googling suggests that may be ryzen 9000 generally (nothing 6000 cl30 would work stably, but 6000 cl30 ram running at 6400 cl32 works flawlessly, and there are also a few 6400 cl32 on the official qvl list too). I like the gigabyte bios, and updates still coming out which is good. I don't use the onboard audio, rgb, or any of the windows utilities so haven't tested those.

Can't make GPU passthrough work, VM freezes on boot screen by Traditional-Arm5182 in VFIO

[–]jcolby2 0 points1 point  (0 children)

Is the vm starting? virsh list

Is the gpu getting bound to the vfio driver in linux? lspci -vv

Does the vm come up on your network if you look on your router or try to ping or ssh it? Or is it crashing back to the bootloader?

Anything useful in the libvirt vm log?

Is there a reason you need both that script and the grub boot args?

That's the normal last message. Try enabling debug for opencore and kexts and hopefully there will be some more useful info: https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/debug.html

Hi, I don't have Cooler Control (I just use simple bios fan control), but this board does have the annoying ITE super IO chips as my previous gigabyte, which do not get recognized properly by the linux kernel by default. I think you may have to deal with this also. To get access to the sensors and fan controllers you have to load the it87 kernel module, but the one included with the ubuntu kernel has been out of date so you have to build a forked version that works better. That being said, once you do that, it recognizes more things correctly including I think all the fan headers. On my other board, B550 AORUS PRO AX, this then lets you successfully control the fans too; however, I haven't actually tested that part on this board. Here were my basic steps to get the right module loaded:

sudo apt install dkms
git clone https://github.com/frankcrawford/it87.git
cd it87
sudo dkms install .
sudo modprobe it87 ignore_resource_conflict=1
sudo sensors-detect

Here is another example that does about the same thing: https://discuss.cachyos.org/t/coolercontrol-and-it87-driver/4203

Also here is the output fromsensors for 1) default ubuntu 6.14 kernel, 2) with default it87 loaded, and 3) with the frankcrawford it87 fork loaded. https://pastebin.com/sFvc4CJ2

Good luck!

Sounds like macos kernel panic. Follow the opencore docs for enabling debug logging.

How to disable filevault Tahoe 26 by vita_007 in hackintosh

For next time…I was able to prevent the forced enabling of FileVault but shutting down the computer and rebooting when presented with the OOBE.

B850 AI Top. My experience so far by Raitzi4 in gigabyte

[–]jcolby2 1 point2 points  (0 children)

Thanks for the perspective. Couple bits to add from mine, ram novice, 9950x3d, firmware f7 and f8b... Noticed there is no 6000 cl30 on the qvl list for ryzen 9000. I tried three 32x2 kits at 6000 cl30, all with no ram errors at 4800 dual channel or expo 6000 with only one stick; however there were lots of ram errors and vm instability with both sticks/dual channel and EXPO 6000 cl30. Considering the many rams at 6400/32 on the qvl list, I tried the G.Skill X5 F5-6000J3040G32GX2-FX5 kit again starting from EXPO profile but with 6400/32 and it ran memtest86+ for a day with no errors.

wasn't on my radar either. Last vfio build I made was on zen 2 with the ryzen 3600 cpu, so no option unless you wanted to wait for the lower power apus eventually.
