    Update #3
    I found I had to use +0.35v DIMM voltage to get the memory to 2.2v. At +0.30v, it was around 2.160v.

    2.2V is not needed on ram, it would only be your warrantied max allowed. I suggest if you plan to keep using 2.2V you have a fan directly on the ram.

    Looks good as far as settings go settings go

    I am not sure how good 1200 would be at 777 compared to 800/444. I can tell you 777-7 and 444-4 will fail. tRAS should always be this >>> tRCD+CAS+2=tRAS

    You will likely have issues getting 2x2 to go to 1200, maybe with 666-20 or 777-20 but it would likely perform badly. High ram speeds like that are best done with 2x1 or 4x1, I just was doing some testing at 1220 with 2x1 at 555-15

    Okay, will adjust DIMM OV a bit later.

    I have a theory why stock voltage wasn't doing too well with 3.4Ghz (was causing Orthos stoppage and a BSOD): loadline calibration.

    When I was OCing before, LLC was on Auto. When I approached 3.4Ghz, I disabled it. I figured that setting it slightly higher than stock Vcore in the BIOS would equal what it would be, if set to stock Vcore and LLC on Auto.

    You can just set voltage higher if your vcore is dropping to far, that would be better then LLC enabled. Should be disabled I think on 45NM CPU, but it is all up to you, there is many discussions about this for sure

    Ram voltage, ya that would be a issue if not set manually

    Thanks. LLC remains disabled. I read an article recently advising this. I did this on the Q9450 too - not that it did any good.

    All is running well now. Temps will probably climb a bit due to the Summer weather in Australia, but I don't seem them reaching 60 anytime soon. :D

    Finallly, it seems my system's lost glory is restored! :)

    Bit of an update. Not really a bad one though.

    I've found that when the E8300 is at 3.4Ghz, I can change the strap to "2.66D", or 5:6 as CPU-Z names it. This brings my memory from 800mhz to 1066mhz. This failed to boot with 4-4-4-12 and 5-4-4-12, but it worked with 5-5-5-12. DIMM Voltage did not need to be changed.

    Tested the CPU to a max of 3.75Ghz, but even voltage adjustments to everything, and loose timings, it did not work. It isn't a terrible loss though.

    EDIT: Tried to go higher on that strap, but when the PC was about to POST, what came up was a weird grey screen, with a single blinking cursor between the top and middle of the screen.

    Back now to the safety of 1:1 CPU+Memory. :)
