    MCH Voltage to 1.2V did wonders with mch skew 200 and cpu skew 100. Tread set to 9 with no problems.

    Going to test these settings with 1066 driving strength profile.

    EDIT: My monitor shut off testing at 1066 with the exact settings above, I came back 2 hours and 40 minutes later and moved my mouse. When the screen came up, it failed at 2 hours and 39 minutes. I have turned it back to 800 for now. Also, I have static tRead at 9 stable, but it will not go lower. Even if I change the timings to 5-5-5-15, increase the mch skew to 250, or increase/decrease the MCH voltage. Lowering the MCH voltage gives me a bluescreen and raising it does nothing. Am I plagued? lol

    At any rate, what can I make better/faster/more stable or rather the next step?

    Try getting 333 MCH to run or Auto MCH with the C memory multi, that will allow you to run a lower tRD

    Monitor shut off? Vista power settings or a error you mean?

    Vista power options shut it off, no errors there. Orthos just failed on my monitor turning back on, probably just a coincedence - I hope ;x, but I switched it back to driving strength 800 cause I know that works good. It will not boot on a 333 MCH and Memory Mult 2.00B. I have to raise tRD up to 11 to boot, and cannot go lower. I will definitely try auto mch and C tonight though.

    It just will not boot through on MCH 333 with anything lower than 10. I tried Auto and 2.66C and that failed as well. I also tried auto and some b settings.

    Gah, I wish I knew what was causing this!

    I bumped up my MCH Volts to 1.340. This allowed me to boot at 333 MCH with a trd of 9. I guess it's better than 10, but is it acceptable or should it still be lower? If I used any lower than 1.340 on the MCH Voltage and I set the tRD to 9 the left hand column would recommend 7, but when I raised the volts it recommended 9 and booted. It seems that anytime the left column says 7 for the trd, it doesn't matter what I pick because it will not boot.

    Could just be your ram, not sure as I am here and your board is there.

    What are all your other settings when trying to load 7-8?

    Hmn, even if I loosen the timings substantially, I can't get the ram to run any faster using the Mem Mult. Do you think I can hit 4.2 on air? Maybe if I increase the CPU Host Freq, which would increase how fast the ram runs also, right? Would I be able to use a driving str profile of 1066 and maybe be more stable? Just trying to figure out how this works, sorry! I do feel like I'm getting to understand my motherboard better though . lol.

    and my ram: Newegg.com - G.SKILL 4GB &#40;2 x 2GB&#41; 240-Pin DDR2 SDRAM DDR2 800 &#40;PC2 6400&#41; Dual Channel Kit Desktop Memory - Desktop Memory. I have 2 kits.

    I think you may be able to use 1066 Driving strength right now. Not sure though, I know I use it at 900Mhz ram speed.

    I also think you will be much more stable if you use 400MCH (Or Auto with a D on your ram multi) With tRD of 9. 8GB is alot to try to keep stable on the 333 MCH

    4.2 on air may be possible if your temps are ok now

    Who needs a warranty? HAHA they cannot tell as long as you do not FRY them with 2.8 or soemthing. You can safely use 2.0-2.1 for sure

    You may also be more stable with a higher vtt and less vcore >>>

    What settings do you reccomend to try 4.2. I stay at about 58 underload during Orthos. I rarely see it go that high doing anything else. I probably don't use enough of the processor. I tried cranking the fsb from 425 to 445-450 to hit 4.2. My hsf goes insane then fails to boot lol. I was like, "Well let's see if this works.... *VRRRRRRRRRRRRRMMMMMMMMMMMMMMMM*... "

    Maybe I'll try 2.1v for ram and then use 400MCH and D to try to get lower tRD.
