Hello Guys,
I build a rig with the following Hardware:
CPU: Intel Celeron G3930 Motherboard: Gigabyte H110-D3A RAM: 8GB Crucial Ballistix Sport LT DDR4-2400 SSD: Kingston 120GB SSD GPU: 6x Sapphire Radeon RX Vega 64 GPU Riser: Kolink PCI-E 1x to 16x Riser USB 3.0 PSU: be quiet! Dark Power Pro 1200W
I use Windows 10 Pro 64-Bit and have Problems to get it running with more than 3 GPUs.
- If I have CSM Enable in the BIOS i can Boot into Windows with more than 3 GPUs plugged into the Motherboard - If CSM is disabled I don't even get a BIOS post, just a the rig running and a black screen
The Problem only occurs when I have the driver installed. So if I plug in all six GPUs wihtout the driver installed i see all of them listed in the device manager as a display adapter (unrecognized)
- If I try installing the driver with the AMD driver package, the rig freezes during the installation process. - If I try to install the driver manually through the device manager, I can see how he installs and recognizes the 1st, 2nd and 3rd GPU after the 3rd is installed the "installation-progress-bar" and the whole rig freezes. - If I install the Driver with only 1-3 GPU plugged into the Motherboard it installs the drivers smoothly without any problems or errors. If I try to add the 4th GPU afterwards and Boot into Windows the system freezes in the login screen every time until I unplug the 4th GPU again.
Here are the BIOS settings I've tried: - BIOS Versions: F22, F23, F24 and F25 - Rig running on internal graphics (iGPU) - CSM Enabled -> system boots with more than 3 cards into Windows - CSM Disabled -> system doesn't post (system is running with only a blackscreen no post at all) - "Mining Mode" Enabled / Disabled -> makes no difference - "Above 4G Decoding" Enabled - I tried enabling "Above 4g Decoding" after I installed 3 GPUs before installing the 4th GPU - "Max Link Speed" Gen1 / Gen2 -> makes no difference - Disabled "Onboard Sound Chip" and "Serial / Parallel Ports"
Here are the the things I've done and already tried in Windows:
- Installing Windows 10 Pro 64-Bit Anniversary Update and Creators Fall Update (created setup USB-Stick with Rufus) - Installed Windows 10 in UEFI Mode -> with GPT partition - Setting virtual memory to 60GB - Disabled "Windows Update Service" - Disabled "fast startup" in the power options - Using AMDs Blockchain drivers - Using AMDs normal drivers - Using the AMD Vega BIOS Signature Check Bypass Patch
I'm glad about any help that i get
