Hi,

One thing I just noticed about the page:

https://www.coreboot.org/Board:asus/kgpe-d16

Here "Crossfire XDMA" is listed as needing testing. If nobody has been able to test this, and you (or someone else) has the opportunity this might be an interesting thing to test.

After learning that this board can take a more modern CPU (family 15h) I'm now considering it more strongly for a future computer. My K10 box is *currently* mitigated against Spectre V2 (IBP disabled under CentOS via a chicken bit) but I don't think it's wise to expect further mitigations to be forthcoming from AMD should more bugs rear their ugly head. Moving up to a family 15h CPU means getting updated Spectre V2-mitigating microcode and a much more realistic expectation of support in the immediate future. I'll probably even move up to piledriver (like the G505s I'm currently working on), since a microcode patch will also fix the NMI issue (and I'll be applying one to the stock microcode anyway).

I'd be really interested to learn if Crossfire and other features of modern cards work on these older boards under coreboot, since they may come in REALLY handy when running any machine learning loads on these boards.

On another note, does anyone have a favorite PSU for these boards? Preferably something that will last a bit longer than crappy consumer gear? This thing already requires two 8-pin connectors for a dual CPU setup, and graphics cards demand them now too.

Sincerely,

-Matt

Taiidan, thank you very much for your valuable feedback! When I've
been thinking of getting KGPE-D16 my main concern was that some high
end GPUs wouldn't work for some reason and it was difficult to find
any info... Luckily your RX580 doesn't have a Security Processor
inside it ! Did you know AMD started putting this "security processor"
crap into their GPUs also, starting with Vega? Hopefully RX line would
be safe for a while, maybe I'd get RX680 when it comes out if it will
not be tainted by this "security" :P Wish you to get a second nice
Opteron one day
