many thanks for your reply
yes
I tried all the "options" and I also removed the CMOS battery.
The DDr3 is sold as 9-9-9-24 1333 / 8-8-8-24 1333 at 1.8 volt
and I can use them at 8-8-8-24 1.8v with the maximum "standard" memory speed tweak ("extreme")
also can use "R.G.B. Robust Graphics Booster @ "Turbo"
the problem is the FSB, if I load the "optimized values" and try to raise the FSB nothing works once I go over 344Mhz
I have tried step by step hundred of times to get a post
raising / lowering the Vcore / CPU Termination and leaving all the others parameters at "normal" and also at "auto"
the only one "success" was at 344Mhz 1.450 Vcore
with 1.400 CPU termination
If I try the same CPU on some of the my other PC (e.g. Asus P5E with X38 chipset ) can get the 400x9 with 1.316 Vcore (@ 43C temp )
p.s.
I does not underrstand the CPU temp value reported by the G41MT-S2
in the bios I can see 21C, but this is not the CPU temp, as a matter of the fact CPUID Hardware Monitor report :
