Unless you run programs which need 32 bit, there isn't any real reason to use that OS. I would personally prefer the Asus board (I won't go into total upgrade). Since the I/O's are identical but the Asus board does support more memory modules (whether it supports more actual ram I don't know but I would believe so). Everything else seems equal.
I have never played with clocks on an MSI board and a quick glance through the mobo manual didn't leave me with the impression much, if anything, can be OC'd that mobo. (I may have missed it though... but I don't think so - I looked through the BIOS section pretty good)
The Asus board does support OCing.
Ahh, I say, realizing the issue. We do not explain how to bypass/reset passwords here (as you've probably already found out) but a quick google search should provide you a few options to get into your BIOS.
Yeah, I know this ain't the topic, and I understand. I've done researching myself and no luck. Maybe I will just return the board and buy a new one. Do you have any recommendations for the mobo though?
