PCI-E bandwidth suddenly degrades with zero errors or warning with 3-Way and 4-Way setups. The only indication is the framerate instantly dropping. The game/app that's running still continues to run.
The only fix for the performance reduction is a reboot of the system.
I've been experimenting with PCH 1.1V and 1.5V settings. I tried 1.6V on the 1.5V setting.... no change. 1.2V on the 1.1V setting... no change.
I'm a picky person and take pride in my systems. I enjoy having a PC that is perfect. 100% stable in EVERYTHING. While I don't get any lockups or crashes with this issue (an issue that happens only during system stress) it still annoys me. I know that I'm part of the 1% of the 1% of the 1% with such a setup, but I think something needs to be done to resolve this issue. I've pretty much exhausted all settings I can try.
The only people in the know would be at asrock, as everyone whos got an EX11 has a bald patch on their head.
Your just gonna have to use the same resources we do for troubleshooting.
You can check a power bug with nvidia inspector, 1 of the cards might be forced into power saving mode while in use which lowers the pcie slot to x16 1.1.
You can watch it realtime with nvidia inspectors multi display power saver app and GPU-Z
