OK so 444MHz CPU Host Frequency (Mhz) is 1066
OK so here are the options.. and its based on if the memory will run 1080 stable
All of the tests will have the following DISABLED
Limit CPUID Max. to 3
CPU Enhanced Halt (C1E)
C2/C2E State Support
C4/C4E State Support
CPU EIST Function
Virtualization Technology
I left the TM function enabled for you for thermal protection. What I posted should lock the processr at the full 8.5x multiplier
Same settings @ 450 placing the memory @ 1080
The CPU Vcore will be problematical and you may need to work this a bit. I estimate 1.28-1.32 will be the range however that may be stable a bit higher or a bit lower than the range
Lower is cooler and always better. 1.38v will be your max and do not exceed it
Start at 1.28v
CPU Termination will be set to 1.25v. This can end up a bit higher as well with a max on 1.35 however I would work that in up by starting at 1.25 then move to 1.28, 1.30, 1.32, 1.34 testing for stability. To be quite honest I dont see this needing to be any higher on the clock we are looking at than 1.28v
CPU PLL will be set to 1.50v and leave it
MCH Core: This is the northbridge voltage and may need to be adjusted from AUTO for higher FSB. Lets start at 1.3v with the possibility of this needing 1.35 or 1.40, or 1.45
start at 1.30
DRAM Voltage will be set to 2.1v and no higher as per the spec from Corsair
Leave everything else on AUTO
Ok.. F-10 save and exit.. she should boot
NOTE: it is possible the system may boot into Windows and be unstable in load tests. At that point you need to do some voltage tweaking.. the same tweaking you would do if the system did not boot at all as I outline below:
If it fails to boot or fails in Windows under stress then enter the BIOS and bring up the Vcore and the MCH Voltage slightly and try again
VCORE 1.28
and
MCH CORE 1.35
If still fails in load tests or no boot it is very possible this memory simply will not do 1080 and that is the problem. To do a quick check enter the BIOS at that point and raise DRAM VOLTAGE to 2.2v leaving everything else as it was and F-10
If it boots then the memory is the issue. At 2.2v you are pushing the outer limits of the spec and although it can be run like that it is past what Corsair specs for the memory and could shorten its life however you can NOT go above 2.2v
If you would rather run the 2.1 spec then the only option is to back down the CPU Host Frequency (Mhz)
At that point lest set the voltages back to the original list I posted above and set the CPU Host Frequency (Mhz) to 444 which makes the memory speed 1066 and boot up
I would think that would be stable but if not, its the same drill as above.. start with Vcore and MCH CORE first and if after you have raised those to to VCore 1.32 and MCH CORE 1.40 you still are unstable post to me and let me know
Now, when in Windows do not use the system properties to see the CPU Speed and the memory speed and timing, use CPUz
At 450x8.5 you should have a CPU speed of 3825MHz
At 444x8.5 you should have a CPU speed of 3774MHz
Both are nice clocks
but
if you are feeling really frisky.. you can try for 4GHz 
This would be a setting of 471MHz CPU Host Frequency (Mhz) and adjusted memory speed for as close to 1066 as possible using the method mentioned above. Check your multiplier ranges at that HOST speed and see if 1066 comes up close to or around 471MHz. Even if you end up a touch slower than 1066.. like 1045 it may be worth the 4GHz clock.
Same deal on the voltages.. you may find you will run just fine at 4003.5MHz
So thats how its done
Now, temps
no matter what speed...
http://www.ocbase.com/download.php?fileext=exeYou need to check for temps and stability in such clocks. I typically use the software OCCT and run the 1hr automatic test. I enter the settings for OCCT and make sure the CRASH or FAIL temp is set to the Tjunction of the processor.. in your case this is 80c
Fire up the test with ReatTemp or Coretemp up on the screen.. there will be a 1 minute prep period then the test will start.. temps will go sky high and that is what we want
As long as the 1hr test passes and your temp remains below 80c you are set on that clock
Now, if you are stable and temps look good you do not need to make any changes however.. if Vcore will drop a tad and stability remain a constant then the proc will run cooler. I estimate you wont get much lower than 1.25 no matter what and in the case of 4GHz it may or may not run less than 1.3v. Some do, some dont.
The next step is to run FSX and make sure you are stable in 3D. If not let me know and we can go from there
