I am looking to get to a 6x Radeon VII rig, but am adding them slowly as I find them for decent price. I currently have 3 installed, but the system will only fully initialize with 1 or 2 active. It doesn’t seem to matter which 2 either. The computer will start up and go through its cycle with all 3 cards lighting up, but it doesn’t send any signal to the monitor. Then if I shut it down, unplug the riser on one and it boots up fine. As I said, any combination of 2 will boot up fine and the cards are recognized. How the hell am I supposed to get 6 going? I thought about it being a power issue, but at full mining they only pull about 250W each so with 3 and the system it is only about 1000W.
Im running
ASUS ROG STRIX B450-F GAMING AM4 AMD B450 SATA 6Gb/s ATX AMD Motherboard
Ryzen 5 3600
1 x 8GB RAM
1600W PSU
On risers with server power
I am in the same boat. I am a TOTAL n00b to mining but have MANY years of PC building experience.
I started with the 2020 VoskCoin edition of the mining rig for under $1k.
I then realized it only has three slots. So I switched to the B450-F because it has 6 slots and I want to stay with Ryzen. I had originally ordered a 3600… and it came with the small fan. So I sent it back and got a 3600x. Then I realized I wanted to use a “G” CPU so that I could use all the GPU’s for mining and “not waste any cycles” of a GPU on the display.
So, I have a Ryzen 5 3400G
The asus B450-F MB
16GB of 3200 RAM (Same as the original build.)
And I have 6 MSI 1660 Super OC’s.
And I can’t get past two GPUs? Right now it has three in it. But it only sees two.
GPU1 is in the far right slight with a riser, closest to the CPU.
GPU2 is in the long slot right next to it.
GPU3 is not attached. It seems when I plug this in and start up, all hell breaks loose and I have to reset the cmos.
GPU4 is hooked up and running in SLOT4. But the machine is apparently ignoring it?
I am running HIVEOS with phoenixminer.
@VoskCoin Can you help us? I have been following you and Red Panda Mining.
Based on the tables in the users manual on page 1-8, I don’t think this motherboard can handle it with a G Ryzen installed. And I still don’t think it can handle it with a NON G Ryzen installed.
With all that said? What are the options at this point? Is there a AMD 4 Ryzen MB that can do this? When you put the integrated Graphics CPU in a Ryzen based motherboard, does that wreak havoc on Mining by eliminating the use of some of the PCIE sockets?
I cannot find ANYWHERE in the BIOS where I can turn the slots down to 1x or even 4x.
I had a 3600, two 3600x’s and this 3400G. I sent the 3600 back. I also sent one of the 3600X’s back as well.
I did build the “pc” in the video. Same case, 32GB of RAM, 3600X CPU, 850W Thermal Take PSU, and I also ordered a 7th MSI 1660 Super OC for it. It’s a sweeeet PC.
But I want to get my miner working so I have set that aside for now.
The most you can have running on this board is actually 5. That is because in the bios settings, there is an option for if, then =. if slot 3 is used, then 2 is disabled. OR if slot 2 then 3 is disabled. I cannot get the why. Also, you have to change the slots to Gen 2.
Its a good gaming MB which is why i kept it. with the VIIs, the most i could run is 5 so i will run it that way, sell my cards when im done, and then use the MB for a gaming computer. The 3600s are awesome CPUs that mine (without adjustments) $12.00 a month.
I found that in the instructions in section 3.6.5…
I had enabled on board Graphics instead of GPU…
I had set the PCI slots like you said…
But now I am back to the RED CPU light again. And this time I can’t clear it. I have had the battery out several times and reset the BIOS/CMOS several times.
The rig ran with two GPU’s for almost 4 days before I shut it down to make the bios changes…
I can’t get past the red CPU light, so I am stuck. Any ideas?
I thought about it being a power issue, but at full mining they only pull about 250W each so with 3 and the system it is only about 1000W.
