Default Re: Can't get 3.6Ghz with E6600/EP45-UD3P

Dual cores also seem to like lower than default MCH ref voltages. With the 1.4Vcore, set CPU Term to 1.2, then set MCH ref to 0.740V. Now increase CPU Term to 1.34V. You will see MCH Ref inrease in value. This is fine, it scales as a % of CPU term.

Also consider setting a fixed Static tRead rather than auto As auto is setting 9, and you're having problems, set both channels to a value of 10 for now. I'm 99% sure tRead isn't an isue though, and auto is setting this very conservatively. You'll likely be ok with 8 or even 7, but after you get stable.

Trying the 2.00B system memory multi may be beneficial, or it may have the opposite effect. D is intended usually for FSB of 400+, so B is still within tolerance for your settings.

One final thing to change. Please enable Thermal Monitor 2. It doesn't cause any stability issues. It's purely there to protect your CPU. It's responsible for initiating thermal throttling when your CPU reaches its TJMax. Without it your CPU may commit suicide by overheating through over zealous clocking or even simply a failed CPU fan.

Regarding the other voltage settings, I was able to get by with lower settings at 400x9: 1.2V VTT, 1.5V PLL, and 1.16V MCH using my 4x1G Kingstons. Higher voltages actually caused the system to be unstable.

Good luck.

Edit: I misread and thought you were running a Q6600. Regardless, I believe what I said above should be still apply to your E6600. There is often not much difference between overclocking the Q/E6600's, except the duo's can often manage a slightly higher FSB.

I'll try all those and report back, however temps are becoming a problem if I go past 1.35, but I'll try. I think my case is the problem :(. In my first post my stable voltage for 3.4ghz was 1.288 in CPU-Z...my CPU is a 'golden chip' so I would think a .2Ghz bump wouldn't require much voltage increase, but I'll play around with it. My VID is 1.2625v by the way. Maybe I should start lowering voltages with 3.4ghz then start trying for 3.6Ghz?
