So...with actualy BIOS I have problem with bclk higher than 115 MHz . 115 MHz is stable, with 116MHz I got blackscreen. Boot with 116 Is not possible. I thought, there will be included some as dividier about 130 MHz as Giga, but doesnt seems. GPU I have at 6xx MHz, so, there will be not problem. Looks like HDD lcontroller limitation?
