Topic: Anyone can test these 6 Pcie slots Ryzen mobos? - page 3. (Read 17999 times)

Hi,
I finally upgrade my rig with x370 carbon and 4 Vega 56 and add 2 Vega 64.
I struggle a bit to get it working. Now every card are up in windows but I managed to get it working only with 5 Vega.
Indeed, the Vega which is on first pcie x16 port getting freezing the computer when I compute with it. And this is a new Vega 64 which I bought.

What do you think? IS it the new Vega 64 that is break or this is the fact to run on the pcie x16?
(I can still return the card and get refund, and I don't have an extra riser to try..)

1. Yes. Strix b350-f gaming
2. Windows 10 pro but i don't know 1703?
3. I try a lot of times. I bought a new psu today. I will try tonight.

1. ASUS STRIX B350-F GAMING?
2. What OS? Install Win 10 1703
3. Look into manual on GPU slots

Hi guys. I have asus b350f gaming. It doesn't work more than 4 gpus with ryzen 1800x. Is there any to work? I updated bios and drivers.

Yes, I have that board and it works fine with more than 4 Vegas.  But I had to update to Fall Creators Update from the Windows site (1709).  And I never enable 4G decoding on these MSI boards.  You need 4G enabled on the Asus boards, but on the MSI X370, I don't know what the hell 4G does expect cause headaches.

Tried. It didn't work out. If I turn off Above 4g decoding enabled, Windows won't detect 5 GPU.
I managed to run 5 GPUs on MSI X370 Gaming Plus, but this shit won't mine at all. Now I used M.2 adapter LM–141X–V1.0 for  5 GPU.
Windows 10 detected all GPUs, installed drivers, but systems stops working after few minutes of mining and reboots. Claymore miner constantly restarts on single M.2 adapter GPU.

Hi,
I managed to get the MSI X370 GAMING CARBON with 4GPU VEGA 56.
I want to upgrade now my configuration, i will try for sure give a try with 6GPU, but i wonder anyone try with more GPU? (i don't find the detail of the motherboard GPU limitation)

Hi,

How do you manage to get full hash power from all of your Vega without an iGPU to plug your hdmi dongle/monitor ?
I'm asking because when I plug my dongle on one of the Vegas, its hashrate falls by few hundreds h/s (1600 instead of 1900), and that's what keeps me away from Ryzen so far.

Try without the 4g decoding enabled.  Especially since you don't have 6 or 8GB gpus.  I had nothing but trouble with this.  Mine won't even post with that option enabled. I'm using the similar MSI X370 GAMING PRO CARBON AM4 AMD X370 and have multiple of these.

Quantity 6 AMD RX Vega 56 confirmed working on ASRock X370 Killer SLI/ac AM4 AMD Promontory X370.  More trouble than other motherboards I listed before but nothing terrible.  Had to DDU/reinstall drivers a few times before it took with all 6 GPUs on my base image SSD.  Worked once I "express" installed the AMD driver back on top of itself again after an initial DDU and re-install.  I've frequently had troubles with Asrock boards in the past (bad voltage regulators in old ones) but don't want to assume it more than a fluke.  We all know how AMD drivers can be.  Working fine for a couple days now.  Nice to have wifi onboard if needed and the price is right for the features.

Wanted to make 5 gpu rig.

According to MB manual it can support 6 gpus with M.2 adapter, but I managed to run only 4.

1) When I put 3 gpus in slots 1, 2, 3 system starts with no problems.
When I add gpu to slot 5 or 6 MB won't start.
2) If I put 4 gpus in slots 2, 3, 5, 6 system starts with no problems.
When I add gpu to slot 1 MB won't start.
3) Slot 4 don't work at all as stated in MANUAL.
Please, refer to pages 28-29 of MSI X370 Gaming Plus MANUAL.

What am I doing wrong?

Need an 8 card ryzen board anyone find any that works with 8?

Modern hardware works better, than old. With new hardware there is less headache, IMHO. Also u get warranty and support of all modern technologies. It's hard to find old quality hardware for decent price.

Thanks.  I can confirm I also had great results with this motherboard paired with a Ryzen 1300X.  6 RX Vega 56 GPUs up and running with no problems at all.  Started with the latest BIOS.  Easiest build yet.

Why connect 6 GPU on the new hardware? For this money you can buy 4 old comp and 2 server power supply for additional power to the GPU. This will allow you for the same money to connect to the work 12-16 GPU. In order not to spend extra money you should always calculate the options with second hand equipment.

We have almost 10 of ASOS ROG STRIX B350-F cards and Ryzen3 1200. We had some initial issues, but after flashing the latest BIOS we could just use default settings and 6 GPUs would work every time, no hassles.

All Windows 10...

I have GIGABYTE AORUS GA-AX370-Gaming K7 AM4 running with quantity 6 of GIGABYTE GeForce GTX 1070 8GB WINDFORCE.  Total pain but working.  I’m not sure why it was such a problem but I was reinstalling drivers several times.  5 GPUS wasn't a problem but the 6th one was terrible to work with.  When I reboot one of the cards goes away.  I even tried a converter in the M.2 slot to see if that would work better but that didn’t work at all (unknown if adapter is good...otherwise untested).  This particular motherboard manual doesn’t mention deactivating any slots like some do in sharing PCI-E lanes.  I learned if I install the driver again while in Windows and then start mining without a reboot it works fine.  Device manager actually shows 6 cards functional this way instead of the 6th card with an exclamation point.  It's been stable so far for a couple days.  I imagine when I reboot I'll need to just reinstall the driver again so Windows sees the 6th GPU and then start mining.  I do NOT uninstall the driver first or use DDU when getting this to work.  Tried that several times in the beginning with various driver version and it never worked that way.  Unsure what's going on exactly and why it won't keep the 6th card on boot without basically overlaying the driver on itself again with a reinstall.

Also have MSI X370 GAMING PRO CARBON AM4 running with quantity 6 of Sapphire Radeon NITRO+ RX 580 4GB.  Not too difficult at all.  It has a BIOS option for “Above 4G memory/Crypto Currency mining”.  Pretty cool to see that feature in a BIOS.  Unfortunately when I select it that system won’t even post.  But no problem with BIOS defaults.

Will be testing a ASUS ROG STRIX B350-F GAMING AM4 soon.  Hoping to get 6 of the MSI RX Vega 56 going.

Update: as I posted earlier, I couldn't get more than 5 working in my asrock. When I put the 6th in it would reboot. I thought on a whim I'd try a different card. So the 1060 wouldn't work but for some reason a 580 magically does. 

What does "it doesn't work" mean? Are you booting Windows or linux? What error do you get?
