Primed for 1 hour error free. Keeping all setting changes.
That was the easy part... :)
Test - FSB FREQ From 414 to 416 using Prime95 - Result: Core 2 Hardware Failure in 4 minutes.
(Verified current setting still cause errors above a 414 FSB Freq.)
Test - Kept 416 FSB FREQ, but increased FSB Term volts from 1.44 to 1.46 - Result: Core 3 Hardware Failure in 4 minutes.
Test - Kept 416 FSB and FSB Term 1.46v, but also changed:
CPU Voltage : From 1.46250v to 1.506.
CPU PLL Voltage : From 1.50v to 1.56.
Result: Prime95 ran error free for 10 minutes.
Test - Restored FSB Term volts to 1.44
Kept - CPU Voltage of 1.506, and CPU PLL Voltage of 1.56, but also increased FSB FREQ to 418.
Result: Prime95 ran error free for 10 minutes.
(I do not believe upping the Term volts was helping me with my FSB wall. I returned them to what the were and still ran clean with the upped CPU voltages.)
Test - Kept CPU Voltage of 1.506, and CPU PLL Voltage of 1.56, but also increased FSB FREQ to 420.
Result: Prime95 ran error free for 10 minutes.
(Short test but looking good)
Test - Kept CPU Voltage of 1.506, and CPU PLL Voltage of 1.56, but also increased FSB FREQ to 430.
Result: System booted into Vista fine, and had the CPU clocked to 3.87GHz, but Core 3 had a Hardware Failure in 3 minutes.
Test - Kept CPU Voltage of 1.506, and CPU PLL Voltage of 1.56, but also lowered FSB FREQ to 425.
Result: Prime95 ran error free for 10 minutes!
I wanted to see if I could successfully run a 430 FSB, but only up the CPU PLL Voltage, not the CPU voltage:
Test - Kept CPU Voltage of 1.506, but upped CPU PLL Voltage from 1.56 to 1.62, and returned the FSB FREQ to 430.
Result: Hardware Failure in 3 minutes.
Tried again by upping the CPU PLL Voltage more!
Test - Kept CPU Voltage of 1.506, but upped CPU PLL Voltage from 1.62 to 1.64, and kept the FSB FREQ to 430.
Result: Hardware Failure in 3 minutes.
Action Taken: Returned the CPU PLL Voltage to 1.56v
Conclusion: My FSB Frequency wall of 414 was being directly caused by the voltage supplied to the CPU's core. My CPU Voltage setting of 1.46250v (BIOS), only will get me my 3.7GHz on my Q6600.
My new CPU Voltage setting of 1.46250v (BIOS), looks to be good for about 3.8GHz. Everest does read lower than the BIOS'es setting, but how high can I feel good about setting my voltage to in the BIOS for my Q6600?
I think I could have 4.0GHz if I am willing to overvolt my CPU a bit more?
These are my current best BIOS 907 settings: Always looking for advice. ;)
