I can hit 2.4GHz(11x220) at stock voltages, but as soon as I bet my FSB to or over 225MHz, the board will not POST, regardless of voltage (tried with VCORE of 1.45v)

Steps taken:
Set HT multi to 3x,
Set RAM to 533 (RAM is 667 OCz)
Manual set PCIE 16x to 100MHz
Set CPU freq. to 225

Board dos not reset CMOS on its own. Have flashed to BIOS v. 0203.
 
Reduce your multi and see if it will go over 225mhz, at least then you could know wether it's the CPU or not.
 
So at 9x I'm able to post this.

VCore is set to 1.45, vRAM is 2.0 (not changed since the board succesfully posted at 200x11)
(Stocks at 1.35, 1.8)
 
set you multi to like 8x and see if it will post amy higher fsb... your mobo just might not be able to run past that....

also check your ram at the same FSB with your CPU lower to know if your ram can handle it...

it might not be your cpu
 
At 10x multi (no other changes), I posted once, windows reported a corrupt C:\windows\system
After this, BIOS would hardlock once I entereds BIOs setup. Cleared CMOS, everything is okay now, all clocks and voltages are back at stock.

At 225x11, board will NOT post, at 225x9, WILL post, at 225x10, will not do anything BUT post. BIOS setup freezes.
 
Okay, thinking it is my CPU that is the problem, I can POST, boot, post this at 250x8 (and 1.45vcore), while 225x11 will only POST, windows won't boot, BIOS setup freezes.
 
Just noticed something funny. BIOS says I set my VCore to 1.45v. Everest sees 1.44v, Asus AI says it's 1.45v, CPU-Z sees 1.36v. If the motherboard had been undervolting my processor, that would explain a lot, but how can I tell withoout a VOM handy?
