So I found an Asus forum where a moderator said once a BIOS is flashed bad it stays bad. When you flash a BIOS on an Asus board it doesn't erase the previous ROM and load an whole new one. It simply changes a few things, so I'm pretty much limited to RMA or order a new BIOS chip (which I will be doing). $24 is worth zero downtime. My system boots, just can't overclock.
He said something interesting about how newer BIOS versions have 2 sets of code, one for SB and one for IB and it can really mess things up. Probably why I can't flash the original 0301 ROM which probably only had SB code.
Here is his post. He was also ticked at some guy complaining.
No, you do not understand what is happening here.
You are talking about a "normal" bios
The 3XXX bios are not normal
After flashing you have TWO CPU microcode loaded at same time - Ivy Bridge and SandyBridge
You are also UPGRADING not UPDATING the Intel MEI from version 7 to version 8 firmware - but ONLY for Ivy Bridge
And since ASUS never mentions what a new bios is doing, it also updates other OROMS or UEFI features we cant even know about. And once a bios is flashed bad - it STAYS BAD!
If you want to argue with me, then I am done here
I didnt type all that stuff just for you to ignore it.
Your safest option now is buy a new chip from ASUS
ASUS bios are locked, so to downgrade you need a flashing system that first erases the chip then writes the older bios.
If it fails then you have a bricked mobo.
Again sorry for hijacking the thread, I hope others read this and learn what rule I should have gone by......... If it's not broke, don't fix it!Edited by Jayjr1105 - 7/16/12 at 6:58pm
