I have set up a few rigs using a number of different boards but this Z97 Gaming 5 from MSI is a bit hassle for me.

So far I've managed to make  6 gpus running stably, the problem occurs when I put in the 7th 1060. There will be an exclamation mark on this gpu in "device manager," in detail it says "this device does not have enough free resources" or CODE  12

I tried several config, but still can't get this to work. Some of those settings include;
1.) Change PCI lane to GEN1/2, latency to 8/4/4 as usual.
2.) Disable all on-board option as possible, it didn't work even I disable on-board LAN.
3.) Tried different bios version as well
4.) This MOBO is a bit old, so even newest bios available doesn't have "ABOVE 4G" decoding.

I think I've seen some people posted their 7-gpu rig using this mobo? so there must be something wrong with my set up?

Big thanks! Now I'm trying some alternative mining OS like simple mining. Will see if that work or not...
