By the way i get a strange result in Everest v5.50 in Cache & Memory Benchmark . There i get 691 Mb/s …

You're right. I am where my profile indicates. But these little things help to forget about the bad things that happen in my country. I wish to patch BIOS to get support of more than 8.5Gb HDD. Слава Україні.

AlessandroB , it's really great to find man with the same mobo. If i am right it's good for you. From my own observation this jumpers on my mobo act as a bridge.
