Gigabyte TR50 or TR50 in general PCIe bifurcation?

Hardware Hub Motherboards

Hi there guys, hope you have a good day/night.

I’m planning to get a Threadripper build with the newer TR 9000, and I was looking at this motherboard.

It has 4 PCIe X16 5.0 slots (or 3 and 1 runs at X16 4.0 if using TR non pro)

I need to bifurcate each lane to X8/X8 to connect multiple M2/U2 SSDs.

Does someone with this motherboard can see if you can set the bifurcation for each individual PCIe lane? I tried searching on the web but no luck or info so far.

Or is there any other vendor confirmed that does X8/X8 on all applicable X16 lanes of TR50?

Thanks in advance!

The ASUS Pro WS TRX50-SAGE is a good motherboard if you need to split PCIe slots for multiple SSDs. Slot 1 and 2 can split into 4× x4 lanes, great for using 4 M.2 drives on one slot. Slot 3 can split into 2× x8, so you can run two devices at full speed. You can change these settings in the BIOS. Slot 4 is limited to x4 and not useful for splitting. ASUS is the safest option for this setup—other brands don’t give clear info about bifurcation.

Just an update, someone confirmed me from the threadripper subreddit, that the Gigabyte TR50 AI TOP can set eah X16 lane to X8/X8, X8/X4/X4 or X4/X4/X4/X4. So I will a keep on eye in that one for now.

At the moment there are only rumors if the Threadripper 9000x series will run on the Asus Pro WS TRX50-SAGE via bios update. As far as I know it is not official yet.
So I would wait until this information is official and confirmed. Otherwise you’ll end up with an MB on which AMD’s Threadripper 9000x series won’t run.

@doc2010 Yes, you are right. It’s not confirmed if the Threadripper 9000X will work with the ASUS TRX50-SAGE. No BIOS update yet. It’s better to wait before buying.

I can confirm that the threadripper pro 9000 series works with the Gigabyte TRX50 AI Top motherboard. A BIOS update is required (using the q-flash utility to get the updated firmware installed).
