"Houston, we have had a problem", a crazy modder supplied the chips with 1.6v even if it's rated 1.32v max. He is even speaking of going up to 1.8v...
7.5k resistor should be the way to go for the actual clock cap. it gives 1.35v

You do risk destroying the chips if you overvolt them. I don't know the absolute limits for the 55nm process (google has not been very helpful so far). Even if they work at a given voltage, the devices may degrade and die at some later time.

I have been ready to post this info back in the old Gridseed voltmod thread back in time, but got distracted too much by Wolfey2014 ads and BS...
...So listen carefully...:
Electronic devices are LIMITED by the underlying technology ...110...65...55.45..32..28nm is how THIN are the individual areas/traces, building the semiconductor's structure/device...
The MAJOR limitation is the DIELECTRIC (SiO2)...and how much Voltage it CAN sustain before breaking...or "start leaking" ...so call "leakage current"...electrons flying from one silicon area to the other...usually "Ground"... This "leakage" increases with temperature exponentially...
I have been looking under "electron microscope" at the 55nm structures...Do you know how thin is it...Like 100 atoms ONLY...that's it...
In summary...65/55nm Devices and Voltages...:
Nominal : 1.15 - 1.25V
Overclocking :
Yellow Zone: 1.25 - 1.45V ...stable, with GOOD cooling...
Orange Zone: 1.45 - 1.60V ...stable, with IMPROVED cooling...
Red Zone: 1.60 - 1.75V ...still stable, with EXCELLENT cooling...
Black Zone: 1.80 and over ...NOT stable, risk of failing to operate...( and HW errorss ...)
Anihilation : 1.85 - 2.00 up ...Chips are destroyed...structures are BURN permanently...
Now you got it... Experiment at your own risk, as usual...
Cheers...( Beer here)...
