Set to lowest core voltage, may I ask can you run 145db SRC @ 96k with e7200 passively cooled stock heatsink?

Thanks

  Well for my setup, it is not possible. But noting that different E7200 could have different default VID and mine is higher than the value posted here.
  
  My current motherboard is not flexible in voltage setting and the voltage is 1.2V. But my guess is that it is not possible because the stock intel heatsink is not very efficient, no copper and no heatpipe, very little fin for airflow. And the stock intel heatsink with fan off feels very hot. The increase in temp. will cause a rise in (dynamic) resistance, making the processor draws more power.
  
  With a cheap and tall aftermarket heatsink with copper heatpipe for passive cooling, the situation improves a lot so that heat will no longer be problem even with 192kHz processing.

    Sometimes XP doesn't take the setting and must be redone. With Max Battery power scheme, VID must be lower than normal.

      Dear Cics, when one is building a cmp from 'scratch or the ground up' should one do the hardware set up in
      
      http://www.audioasylum.com/forums/pcaudio/messages/3/33137.html
      
      first then do the Bios and Power set up from CMP documentation 'The art of Building a computer transport' second or vice versa? Or should it be simultaneous?

      • Only do BIOS setup as per post - AOB refers to Biostar mobo. - cics 12:34:45 08/11/08 (1)

        Power setup is as per AOB.

• Yes, 145db SRC @ 96k with e7200 passively cooled is not a problem. - cics 00:19:03 08/08/08 (0)

  You can do this for all Core 2 Duo processors as long as passive cooling is good - no need to go overboard.
  
  My E6300 does 145db SRC @ 192k with passive cooling. Temp is ~65°C using Thermaltake heatsink. E7200 does ~25°C with Zalman case.
