I have used Original 1201, 1301, 1402 and they all work fine for me, but 1201 and 1301 seem to OC better then 1402 .. 1201 is really good, 1301 is about the same just added more memory support.

I also Kets modded version of those i listed and no difference for me as they all the samething just ket added more CPU's to be supported and more memory in the table from the premium bios.

So 1201 - 1301 are the best of the best, just if your in need of a modded bios for more memory table support and CPU .. then sue KET's modded version.
