    Ya kick you are correct, Auto Rem Ref would be 50% of ram voltage and will auto adjust >>

    CPU Termination (Vtt) Automatically changes the following if manually set >>>

    CPU Reference Voltage (.63% of Default Vtt/1.20) .76 ET
    CPU Reference2 Voltage (.67% of Default Vtt/1.20) .80 ET
    MCH Reference Voltage (.63% of Default Vtt/1.20) .76 ET

    DRAM Voltage Automatically changes the following if manually set >>>

    MCH/DRAM Reference Voltage (.50% of Default Dram Voltage)
    DRAM Termination Voltage (.50% of Default Dram Voltage)
    Channel A Reference Voltage (.50% of Default Dram Voltage)
    Channel B Reference Voltage (.50% of Default Dram Voltage)

    Great to hear you are getting somewhere!

    I'm having the same problem with my rev 1.1 board and F9 final bios. FSB 400 x 8 and every time it comes out of S3 sleep it ends up in the dreaded reboot loop. I have OCZ platinum ddr2 pc6400 ram running at 2.00D. Was running this ram and processor at the same speed in a Gigabyte GA965P motherboard with no issues. My bios has everything at auto except for the cpu voltage at 1.35 and LLC turned on. Ran the normal suite of memory and prime95 tests and was stable for hours. 390 x 9 works without any S3 issues, but wtf.

    Sorry if I made it sound like I got S3 to work correctly because I did not. I turned it to S1 in the bios and forgot about it.

    I never did get as far as I wanted with my overclock. My Q6600 needs more than 1.5 volts to be stable at 3.6 and I didn't feel like messing with it any more.

    I ended up just keeping the cpu at 8 x 400 with the ram at 2.00D with timings at 4-4-4-12. I lowered the advanced timings pretty good down to 3-3-3-48-3-2. Might be able to go lower with the advanced timings but haven't tried. Nice and stable, though.

    UPDATE:

    I put a Q9650 in my board along with another 4GB set of the reaper 1150s and S3 is working great at 400x9 with the memory at 2.00D(haven't tried higher memory speeds if anyone is wondering).

    My Q9650 has a vid of 1.275. I left the Vcore at just that which keeps the voltage at 1.232 at Idle AND Load with LLC on according to CPU-Z. It's nice and cool and stable at 3.6GHz. Intel Burn test 15 passes with temps in the high 50s according to RealTemp with my Xigmatek.

    I lowered the voltage of the Memory down to 1.94 which keeps them at 1.9-1.91 according to Hardware Monitor. I kept the timings at 4-4-4-12, the advanced timings at 3-3-3-48-3-2, static tRead values at 7 and drive strength profiles,I think they are called, at 800.

    I probably won't overclock any more any time soon, though it looks like I might have quite a bit of room left if I decide to.

    I'm just happy S3 is working excellent at higher clock speeds now since I had the Q6600 at 333x9 to keep S3 working!!
