GA-EX58-UD5 QPI/VTT Voltage for TR3X6G1866C9DF with 920 D0

Hi

 

I’m building a i920 D0 - GA-EX58-UD5 - TR3X6G1866C9DF system currently stable at 190 x 21.

 

In “Core I7 MB Settings By X58 MB” QPI/VTT Voltage of 1.415 Volts is given for GA-EX58 mobos.

 

In “Dominator Qualification and Testing DDR3” QPI/VTT Voltage of 1.6 Volts is given

 

But in a recent post “Can't get TR3X6G1866C9DF past 1333 Mhz” there is a recommendation to lower the QPI/VTT Voltage to 1.35-1.4 Volts.

 

Are the other two references for pre D0 920s and the QPI/VTT Voltage should be 1.35-1.4 Volts for a D0?

Hi

 

Thanks for that.

 

I was trying to get confirmation the D0 requires a lower QPI/VTT than earlier steppings. Corsair may wish to consider qualifying the two "stickies" I referred to.

 

For 191 x 21 I had started off at CPU Vcore = 1.30000 & QPI/VTT = 1.415 I'm now down to CPU Vcore = 1.29375 & QPI/VTT = 1.375 hopefully will get lower.
