If nobody has been able

It is simply PCI-e P2P DMA nothing special so I see no reason why it
I don't have the money/need for a second RX580 so I can't test it.
If you want to play games the G34 6328 is what you want, or if you get a
KCMA-D8 the C32 4386 - the piledriver cpus are faster than the bulldozer
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.
Like I said it works fine - you can have a total of 2 dual width cards
or 4 single width PCI-e cards plus the PIKE HBA/RAID slot which is
actually just a PCI-e x4 reversed slot on the data side (the longer side
is the ports fan-out)
Of course I would suggest you instead purchase a TALOS 2 as it would be
faster, less expensive and give you much more options. Obviously you
can't play x86 games on one but folks have already ported a few foss
indie games to POWER and unreal engine has a demo.
Note the lite version has only two pci-e slots and the recc'ed regular
talos 2 must have dual cpus for all the slots to be used so dual 4 core
is better than one 8 core.
Arguably the most impressive TALOS 2 home setup yet :D
As always if you require more PCI-e slots on a single board for whatever
reason you can purchase a PCI-e expansion system from cyclone
microsystems, of course one should consider their uplink requirements
(and get at least pci-e 2.0 x16 uplink) although for P2P and VM
assignment the onboard PCI-e switch supports ACS so there is no issue
there. They appear on fleabay now and again and seem to be made in usa
just like the talos 2!
On another note, does anyone have a favorite PSU for
I recommend something from seasonic they seem to make the best stuff
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.
The PCI-e power connector is different and not compatible be careful
when you hook up your stuff!
