Hello Fatman
Yes I´ve tried with just one RAM installed, in both a orange and a black slot. No difference. According to Gigabyte this CPU is supported after BIOS F9 and I don´t know my BIOSs version. I´ve tried to reset BIOS, to take out the battery (witch is out and waiting now), different GPUs, I tried to boot with a PS2 keyboard. Right now all I´ve connected is the RAM, GPU, CPU and a keyboard and I´ve allready tried to take it out of my case and put it on a magasine....
I really don´t like to remove the CPU but I can try, I was carefull when i installed it but you don´t know.
My setup is:
Gigabye x79 UD7
Intel 3820
Crusial Ballistix Elite 4x8GB RAM
Corsair H100 CPU cooler
Gigabyte 460 GPU (x2)
