Hi All,
I have 10 Zotac 1080 TI Extreme GPUs, running on windows 10, 64 bit.
Windows updates & Nvidia drivers are all the latest
I have 3 GPUs out of the 7, which start hashing at 750 Sol, but after few minutes they drop all the way down to ~300 or even ~250
I have tried different power risers, different PSUs, different PCIe slots, nothing has helped
The same 3 GPUs will always start at 750 and go down to ~300
The same 7 GPUs will start at 750 and stay at the same level, no matter how i swap the PSUs, powered risers, slots, sockets, etc...
The display is connected directly to the motherboard not to any GPU All GPUs has power state of P2, so i dont believe that one will do 750 and the other 250 because of this
I tried different miners, but the two showed absolutely the same result. 3 GPUs badly perform and 7 perform very well
I noticed that "memory controller load" on the high performing GPUs is about 80% while on the badly performing GPUs is around 55%, using Hardware Info software. Is this the root cause? Any idea how can i fix this?
