Hello:
I am planing on buying a new cpu but my mobo Asus M3N78-VM needs flashing bios for diferent revsions. I rather not doing it again. I have revision 1309 right know and I am looking at one CPU that will work but it has two diferent revisions. One of them needs flashing the bios since is higher. How do I determine the revision number if the specs on websites do not tell me the revision number.

Thanks in advance.
