This is a UpDate to this thread and also my question. I was unable to get the z690 Apex working with a Quad - Setup ( I also did not want to BORK the board AND did not try harder). <- If anyone gets this to work, PLEASE leave feed back š
I went back to my z690 Hero ( BIOS 3401 ) and have Benched/Submitted scores from both 2x SLI (GTX-6xx) and Quad SLI (GTX-590/690).
^ The Asus z690 Hero and Gigabyte z690 Aorus Tachyon <- From Scores Submitted by MATSGLOBETROTTER ā CAN run Quad SLI - For those that are interested. š
Thank You For Your Time š
