M2N32-SLI Deluxe+AMD 6400: Best BIOS for AMD Athlon 64 X2 6400+ Windsor 3.2GHz ??

Dear all,

Since I am having a BIOS problem and need to reflash eventually, what is the best BIOS for the CPU I am using?

AMD Athlon 64 X2 6400+ Windsor 3.2GHz

I have read in this forum, version 1201 is best for X2 and 1802 best for Phenom, is this the concensus?

Thanks in advanced!
