I am wanting to increase voltage to my 580's. Currently at max of 1.213 I want more with out a hard mod.
Is it possible?

 I can do 1000/2000/2350 now.

30ft pipe tape insulation, check.
24ft tube 1/2" ID insulation, check.
Ice, check.
Water, check.
40 screws and nuts for fans, check.
 
Total cost, $35. Awesome right? 

Hey Awalleye, just passed 21x210 with +50VTT. With almost 1700Mhz RAM, trying to figure out 21x211 though, to stay with the low VTT.
 
Keep getting 9c BSODs, John said that was RAM related so I'm trying the timings now.

Only like 2*C, good but not that much lol.

Hehe yeah, 4.53Ghz(21x216) passed, about 66C load. 217x21 failed after 27 seconds, gave me a x124 BSOD.

  Best yet?
I believe the rated FSB is directly related to QPI PLL once you go over 4Ghz stability becomes hard. So increase of QPI PLL may be the answer. Along with other tweaks of which will depend on your particular CPU. Speculation of course.
 
Edit:
  Now having no experience with the "930" I really would like to see you try with the default multi.
I have tried to figure out which voltage(s) apply to the multiplier but to no avail. Because I have seen where a chip can OC higher with a lower multi and higher QPI, but I simply do not accept the even odd deal. I really think there is a voltage(s) that affect the efficiency of the multiplier. And it does not necessarily mean a higher voltage simply the right combination of voltages and of course varies from chip to chip. Again all speculation of course. 

same here halo, ive had 2 930s and both were the same easy to get stable with 22 multi @ 200bclk but not a inch further. 

can you get turbo to kick on @200???? My board never could but 23 multi should be good and stable.  That makes for an easy 4.6

Hey Reggie, using the 23x multi right now, doing suicide runs for CPUz, what do you think about trying to use 23x for Vantage and Wprime?

Never mind, apparently when you put a load on all eight threads it drops back to 22x.

Hey Reggie, using the 23x multi right now, doing suicide runs for CPUz, what do you think about trying to use 23x for Vantage and Wprime?

   So if you use 23 multi instead of 22 can you OC better than using 22?
I understand that 23 goes to 22 under load just asking.

not really sure never really figured it out to tell you the truth. It has something to do with the amount of power the cpu is pulling. with default settings turbo was designed to kick in when the cpus were loaded but thats not really the case with oced chips. That being said when you drop down to one core you can use the 23 multi freely set in the bios which is good for super pi runs just turn all other cores off. Youll be able to get away with more voltage that way too because your chip won heat up under load. My max cpuid on water is with one core and 23 multi hit 5ghz

Wow that almost makes the 970 reasonably priced.    Good thing Ipicked up mine through the intel retail edge program or I would be pissed.

Whoa nice!
 
Edit: On looking it's still 899 for me.
