Has anybody been able to get 4 GPUs to run on an Asus Prime B350-Plus? Ive tried everything. Help!
See my post below for what Ive already done to try and fix it. Also now hooked up two psu's and both work fine. The secondary 1000W pushes one GPU, the main 1600W pushes two, the fourth GPU is on but not working (connected to the 1600W main).
My mobo does not have the option to enable 4g decoding or forcing pci to gen 1. I don't have experience with Hive OS? Would that involve changing the OS to Hive or can it be done explicitly from the USB.
Still fairly new to computer programming/troubleshooting.
Hey everybody. I recently upgraded to a fourth GPU (1080 ti Hybrid) on my Asus Prime B350-Plus and Ryzen 7 1700, dedicated miner. I have not been able to get the fourth GPU to operate. When I have four gpus connected, the PCIe 2.0x16_2 shows this error: "Windows has stopped this device because it has reported problems (code 43)".
These are the things that I have done so far:
- checked all connections to gpus, risers, and pci slots
- plugged in the new gpu to all the different pci slots and different risers to ensure that it was working properly.
- All gpus, risers, and pci slots work with up to a three gpu configuration.
- updated the bios to 3401 version (current on ASUS website).
- Connected gpus to all different power rails on the psu (1600w evga T2).
- Updated driver for the new 1080ti (the update manager said they were the newest version, but I updated anyway)
Any thoughts?

did you enable 4G Decoding and set pci express to gen 1 ? if you did and still doesn't work use hive os on a usb drive or something see if it brings other gpus up.

There are not enough free PCI-E lines.
The upper port uses lines from the processor.
The lower x16 uses the lines from the chipset, which means x4 mode.
And it is indicated that he divides them between x1 slots.
Specifications: PCIeX16_2 slot shares bandwidth with PCIeX1_1 and PCIeX1_2.
I was able to get the 4th GPU running when I unplugged the PCI2 port. The configuration that works is as follows:
PCIeX1_2 - Connected via X1 riser
PCI2 - Not connected
PCIeX16_2 - Connected via X1 riser
PCIeX1_1 - Connected via X1 riser
PCI1 - Not connected
PCIeX16_1 - GPU directly connected to motherboard
If I get another GPU down the road, do you think the PCI1 or PCI2 slots will work with this configuration? I will probably get a X16 riser for the main (PCIeX16_1) slot, if I do get another GPU. The PCI2 was not working, but I have not tried the PCI1 slot yet.
Thanks for all the posts trying to help!! Happy new year!
