Finally got my installation going. Still burning in hw.

After 24 hours, Vcc is 0.69375V (CPU Z @0.704V). However, I have some differences to your setup:

Disabled HPET Support

Set QPI Clock Ratio to 24x (can't get anything lower) yours is at 2.2GHz (I have 1.2GHz) as per CPU Z

Use Auto DRAM timings at 6x speed

Adjust Graphics Core voltage - I can get to 0.650V you have it at Auto

Can you test on your side?

others is fine.. but i cant go to 0.65 on graphics core. - lga775 09:59:33 05/04/10 (6)
it did not work when i touched graphics core dont know why.. haha.
it troubles me lot to reset the bios when i disturb the graphics core. haha.
- Graphics core now at 0.625 - try setting "Internal Graphics Clock" to 400 (lowest) instead of Auto. nt - cics 10:10:44 05/04/10 (5)

  - yes the graphics clock is 400mhz, what is the fail safe voltage for graphics? - lga775 10:18:33 05/04/10 (4)
    - Lowest for clean boot is 0.612. Another feature of mobo is "Cryptographic Services" which needs new approach - cics 09:05:54 05/05/10 (3)
      You cannot stop "Cryptographic Services" as on reboot service persists. Solution is to remap "Rip" button in cMP to disable it. You need to create a .bat file say "c:\cryptsvc.bat" with following:
      
      @echo off
      sc stop cryptsvc
      
      Remap "Ripper" button in cicsMemoryPlayer.pth file to:
      
      RIPPER #H "c:\cryptsvc.bat"
      
      On boot, simply press "Rip" button to stop this nasty service (which impacts sound quality). Screen flashes and cMP does a refresh. Thereafter only 2 services should be running (PnP and RPC) - if using mobo soundcard then a 3rd service, "Windows Audio" is needed.
      
      Update: still running stock CPU cooler with temps at 23�C doing 192k SRC@145db output. Tried disconnecting fan and this gives ~53�C using Intel's little heatsink! Impressive considering these CPUs can run to ~73�C.
      - Good News!!! i am able to set my Graphics voltage to 0.65 as well as 0.65 for Vcore!!!! - lga775 05:01:03 05/08/10 (0)

        On the subject of CPU temperatures:
        
        I have had poor experiences of Intel processors running their thermal management algorithms at almost 50degC below rated temperatures - backing off clock cycles to reduce thermal stress on the chip and inducing (in my case video) playback issues.
        
        My recommendation is always keep well away from rated temperatures, the internal chip temp sensors are crude, not calibrated and thermal algorithms are not published...
        
        Core i3 CPU temp measures matches RealTemp - this is a fisrt - cics 10:42:55 05/05/10 (0)

        Not sure if you using Core ix CPU but this model is a first for matching RealTemp measures. On long runs I'm getting a stable 26�C.
        
        PROCHOT condition causes degradation you experienced - this is very rare in low voltage & frequency setups.

Hi CICS, I'm also interested in similar setup. In due course, can you report the improvement in SQ and power consumption when comapred to other set up e.g. G31 + E7X00 combo?
