Currently I have the P7H55-M/BR ASUS Motherboard, CPU and an Intel Core i3 540@3.06Ghz, I tried a few times to overclock my "CPU" to play it at 3.4GHz, however impossible that my mobo therefore, it seems that the BIOS is locked / blocked, ie there is no way I increase the "Clock" my processor, and also not the option for me at least increase the FSB, VCore, the only option that is released is the multiplier, however it is just 23.0x, or 23.0x multiplying this value of the "Bus Speed" which is 133.3Mhz, it's the sum of the resulting 3.06 GHz 3066Mhz. However, I heard these days is to overclock my mobo by "Jumpers" that is in the board, I do not know if this proceeds or not, then you would try to remove that doubt me, or heal it with some other way. Many people also showed me the BIOS change it, they told me to get the BIOS from ASUS P7H55-M, however this process is very risky and I think that I could not do the same procedure, that is counting on your help. Already tried the latest bios and continues. thanks
