65nm GTX 260 safe voltages and EVGA VT
So I finally got antsy and really wanted to push my shaders past 1458 on my BFG GTX 260. The highest overclock I can hit on stock voltages is 729/1458/1000.
I downloaded EVGA's voltage tuner and started slowly upping to voltage until I hit 1188mV - and found I could get my card to 756/1512/1000 stable. I only have two questions right now:
1) Is 1188mV safe for my 260? Default voltage is 1125mV.
2) Is it safe to have GVT auto-bump the voltage up when windows starts, or could this cause problems from the instant bump in voltage? I.E. if I find this overclock is 100% stable and 1188mV is safe for my card - would BIOS modding be a better option?
I'm not as familiar with GPU voltages as I would like to be, so I'm not sure how a 63mV bump would affect my card. I know that 63mV = 0.063 V which isn't much to worry about with most CPUs for example. What I'm looking for mainly is some sort of correlation between GPU voltage steps and CPU voltage steps.
