i give up trying any more with x38-dq6 , two afternoons spent for nothing, cant get stable 450fsb , no matter what... (with 1.475 MCH -too high already- get random lock ups..), ill stay at low 9x400/1.1 and be "happy" :S .there is a hope in future if i change my ram to some fast 1066+ so with anything than 1:1 the chipset will be much more relaxed.. , but for now "nisafi"- enough
