X58 UD4 - Voltage Questions

[earlydoors]

Hi, I have the X58 UD4, overclocked to 166 Bclk = 3360Mhz and undervolted.

Voltages are

VCore: 1.1875V - manual
QPI/Vtt: 1.155V - manual
IOH: 1.100 - manual
DRAM: 1.600V - manual

System is stable after 8+ hours of P95, can someone advise me as to whether my voltages look okay?

I'm not sure what QPI or IOH should be set to.

Please help

Thanks

Hi .

Looks like you have a nice overclock there and your settings look fine to me. QPI/Vtt is perfectly within the 0.5v of the memory voltage which is important. Well done.

Thanks 

I've dropped VCore down one more (I can't remember the specific voltage) and am stability testing now.

Do you have any information about the IOH voltage?

Yes standard is 1.1v so you a bang on
