I recently turned an old gaming PC to a 6 GPU mining rig which is working fine. After installing the 7th GPU, the rig won’t POST no matter what setting I use in BIOS and this message shows when turning the PC on after removing the 7th card:
“The memory address is insufficient due to Intel Thunderbolt resource consumption.
The onboard Thunderbolt is now disabled for better system resource allocation.
Strongly suggest to press F1 to enter BIOS setup and manually disable unused I/O peripheral controllers. (Recommended items: SATA/LAN/Wi-Fi/Thunderbolt controller.)
Press F1 to Run SETUP”
Things go back to normal with 6 GPU’s.
Specs: Asus Z87 pro v
8 GB RAM
- PCI-e set to Gen 1 and Above 4G encoding enabled in BIOS.
- Unneeded resources are disabled in BIOS.
- Currently 2 cards sit on x16 slots and 4 on x1 powered risers. When adding the 7th card, I tried 3 on mobo and 4 on risers, then 2 on mobo and 5 on risers but still no good. I never tried an all risers configuration yet as they are not available right now.
Could it be that the Z87 chipset can’t handle more than 6 cards at the same time?
Any suggestions are welcome.
