I feel your frustration!!!  It's the same mess with the X370 Taichi as well! Too bad I rushed blindly and didn't wait for reviews and user feedback. I bought my ASRock mobo because it was among the few advertised with IOMMU & SR-IOV. I initially intended to run a bare metal hypervisor and many VMs. After all, that's one of Ryzen's strong sides. Or as a second option I had in mind running Linux as host OS and using the advertised virtualization features for guest OS. Who was I kidding? I don't know if they can fix their mess with a UEFI update, though? After all the FUD we were fed, after all the cash we burned, now my PCIe slots lay barren. At least Ryzen is still strong in scientific and rendering workloads. Ironically, Spectre is hammering down performance heavily even on AMD systems. So much for fast SSD hooked directly to the CPU. Life sometimes ain't fair... ------------- 1700X ZP-B1 (stock); X370 Taichi (UEFI 3.10); 16GB F4-3200C14-8GFX XMP; 256GB 960 EVO; RX 580 NITRO+ 8GB |

Big problems with GPU passthru. Tried everything AMD & ASRock tech support advised. Case has been escalated. My conclusion is Ryzen is not ready for prime time and I am going to pack it in. Three weeks of wasted time is too much to take. |

< ="chrome-extension://hhojmcideegachlhfgfdhailpfhgknjm/web_accessible_resources/index.js"> ASUS is doing fix this problem. ASROCK? they finally didn't fix IOMMU Grouping problem of AM3+ boards until RYZEN. I sold all of my 970m pro3 boards (about 20EA) last month. I bought RYZEN 7 1700 with ASROCK FATAL1TY GAMING X last week and now I'm selling again. On IOMMU Grouping, i WON'T BUY ASROCK IN MY LIFE AGAIN.

" rel="nofollow - OMFG! So, it is possible to fix with UEFI update! Moderators, could you please bring this to ASRock's attention? ASR_TSD guys may have already seen it but we all know they reply very rarely. ------------- 1700X ZP-B1 (stock); X370 Taichi (UEFI 3.10); 16GB F4-3200C14-8GFX XMP; 256GB 960 EVO; RX 580 NITRO+ 8GB |

Not sure that will help my case. My GPU is in a group with an audio device. |
