Hmm, probably not, but if you're comfortable flashing then go for it. Generally you find better stability and whatnot through custom BIOSs but I don't know of any for MSI
If you had bought the gigabyte board instead of your msi you would not have to worry.
Dual BIOS prevents losing your BIOS if a flash goes bad.
Yea but go ahead and flash it you should be fine. I'm such a daredevil I have flashed my ASUS BIOS twice from within windows. And nothing happened to me.
Not always. I was trying various custom BIOS's to see if one would provide better stability for higher FSB OC's.
This D27 from TicTac for example won't even post at 230MHz (DDR460) but with the previous one I had D26 Blackmantaray XT it would post up to 250MHz (DDR500) but obviously it wasn't anywhere near windows stable. Getting a 1gb of RAM to actually be stable at that with a socket A system is pretty much impossible
