I am running into an issue here that just doesnt seem right to me. If I try to change from 9x450 to 10x450, I have to raise the Vcore very high just to get it to boot into windows and even higher to get it to start to become stable. Way to high I feel, but I really dont know. I went back to my Dominator 1800's because they are completely stable, the OCZ is not yet.
Here are my stable 9x450 settings:
Quantum BIOS Version G27
Overclock Phase Select - Manual O.C.
CPU Clock Ratio - 9x
CPU Clock Ratio +0.5 - Disabled
Target CPU Core Speed - 4053 MHz
CPU Clock (FSB) - 450 MHz
CPU Clock vs Memory Speed - 1:4 CPU333
System Memory Speed - 1800 MHz
CPU Clock Skew Control - 0 ps
CPU Clock Amplitude CTRL - 800mV
PCI Express Clock - 100MHz
PCI Clock - 33.6 MHz
Spread Spectrum - Disabled
Overclock Recovery - Enabled
All Voltage Control
CPU Voltage Multiplier - x1.000
CPU Voltage Setting - 1.4750
CPU Vdroop Compensation - Enabled
CPU PLL Voltage Setting - 1.584304
CPU VTT Voltage Setting - 1.350
CPU GTL Ref. 0 Voltage - +10
CPU GTL Ref. 1 Voltage - +5
CPU GTL Ref. 2 Voltage - +10
CPU GTL Ref. 3 Voltage - +10
NB Voltage Setting - 1.673
NB GTL Ref. Voltage - +3
SB Voltage Setting - 1.538
DRAM Voltage Setting - 2.044
DRAM Pull-up Voltage - +3

With those settings I am rock solid in Prime95, OCCT and SuperPi. So I thought I would try 10x450 which is my goal with this MB and my setup. All I have done was to start raising the Vcore. It's scaring me a bit so I have stopped for now.
Vcore to 1.6 = will finally boot into windows
Vcore to 1.6528 = will do 1M S-Pi but only last about 5 sec in Prime95
Vcore to 1.7 area (forget exact number) = will last for about 30 sec in Prime95
I couldnt go any farther because I was too worried and the temps were way to high under load, pushin low 80's.
Is this normal for this MB to need that much voltage for 4.5GHz? Or could it be the CPU that needs that kind of voltage for that speed? I have not touched any of the other settings which may be a part of it. I'm just wanting to know if this is excessive for this speed is all. Any thoughts?
