and X1900XT VS. X1900XTX + OVERCLOCK VOLTAGE GUIDES

[Astennu]

I have a VF700 on my X1900 XT board. So i redused the stock voltage.

I'm running 600-750 @ 1.15v and 1.9v for 2D and 3D now. It uses a little bit more than the 500-600 @ 1.2-2.1 stock. Because of the high clocks. But its silent and quite cool. The VF700 cant handle Stock X1900 XT 3D clocks and voltages. it will run @ 80c or more with fan @ 100% (12v).

So i need A VF900 or Accelero X2 The Stock cooler is a bit to noisy for me. The plastics hood arround the fan is causing that noice by resonating at the fribrations of the fan. But the Stock cooler peforms realy well. A Accelero @ max fan speed wil have a higher temp than a X1900 Stock @ 100% but it will run more silent.

1.55 is much :| i would not date to use it unless i can run @ 60c max. But i well need WC cooling for that. Also take a look at the VDDIC Voltage in ATi Tool. It will help you run your ram more stable. Without i raising that one i could not run 800 MHz without iminate artifacting. If i set VDDIC @ 1.58 i can run it artifact @ 800 MHz free up to 80c core temp. After 80c is lockup.
