C_Payne do you have a recommended motherboard for your x4x4x4x4 itx riser?
Either asrock x299e-itx or x99e-itx.
Or the server counterparts from asrock.
I don't have any of the behind itx in stock currently.
Let me know!
That's so disappointing that I'd have to step all the way up to that board.... With people demoing a 4x m.2 card for Ryzen 3000 maybe we'll get x4x4x4x4 support on x570. Because I'm really pondering a PfSense router with 10G ethernet cards.... And your riser board looks perfect if someone would just support it on a reasonably priced platform. I'll potentially order one in a few months... IF x570 supports it. I love your work though! As a case scratch builder I'm seriously looking at your risers and pondering builds.
C_Payne Gigabyte posted the manuals for most of their X570 motherboards, their itx board will support 4x4 bifurcation
"PCIEX16 Bifurcation Allows you to determine how the bandwidth of the PCIEX16 slot is divided. Options: Auto, PCIE 2x8, PCIE 1x8/2x4, PCIE 4x4. (Default: Auto)"
That is awesome news! Ryzen x4x4x4x4!
Update on my PLX work:
It does work with some Lanes missing (maybe bad BGA solder joints?)
Assembling took me a whole day though.
Lets see if I can make these available sooner or later.
Has anyone been successful in modding a BIOS to engage in bifurcation? Specifically an Asus Strix X470-I? Although I would be interested to hear success stories with any board.
Edit: I'm aware of www. win-raid. com/t3323f16-Guide-How-to-Bifurcate-a-PCI-E-slot.html
How does this work? Does the bios have to support the PLX application? I'm familiar with the theory of PLX, but how does this turn out in practice when it's not implemented directly on the motherboard?
When can I buy one?
BIOS support is not necessary AFAIK. Otherwise dual GPU cards wouldn't work either. It works fine with my X99E and it should work with any mainboard.
The issue I currently have is that I haven't figured out a reasonable way to manufacture these in little quantities.
Hand assembly is NOT an option, took me a complete day.
I will keep you posted.
Do you have any news for the DAN A4?
Unfortunately I had no time yet to work on the dan-project. Also I will be on a vacation for the next 3 weeks, so it will have to wait a bit longer. But I won't forget about it!
Thanks for the quick reply.
No problem. Happy Holidays!
Any word on Ryzen 3000, X570, and pcie gen 4 with existing bifurcation risers?
Have a ryzen 3000 and rx 5700 ordered, will report next week when back from my trip.
I'm fairly sure the MSI Creation supports it at least -- it comes with a M.2 adapter to put 2x M.2's in a PCIe 8x slot -- no PLX chip. I actually have the board but no cpu/ram yet but I will be getting the rest of my parts in over the next few weeks.
Oh, and PLX update please.
