In order of priority:

1. Try lower QPI/DMI link multi in bios

2. Lock PCI-E at fixed frequency not auto (like 99-100-101-etc - several attempts)

3. Try single channel

I lowered QPI/DMI link in bios and tried singlechanel helped a bit i can now go for 225FSB with i3 530 i will try tomorow with another CPUs if i am bricked at 225FSB or it is just bad bin cpu and cant hit higher FSB thank you :)
