have u tried to disable 4G like suggested here ?
With 4G disabled I am only able to get up and running with 2 cards......... As soon as I insert the 3th one I see only a cursor blinking. Not even possible to enter the BIOS.
With 4G enabled I can get up and running with 4 cards..........
Any other ideas?
Have u tried 4g disabled (with just one card installed) and adding Card 2 - Reboot - Card 3 - Reboot - Card 4 - Reboot - Card 5 Reboot ?
Or .... disable 4G, boot with 1 card, install it and then shutdown. Connect all the remaining cards, boot, enable 4G, voila.
You made my day. I feel like an idiot now because i was allways adding 1 by 1
