Never overclocked anything so be kind. System spec in sig below. I found a link with some supposedly stable clocks for my GPU (http://www.guru3d.com/articles_pages/evga_geforce_gtx_780_classified_review,27.html)

Power target = 110-115%
Priority = Temp
GPU clock = +140MHz
Mem clock = +425MHz
Voltage = +37mV
Fan control = default

So I switched to the 2nd BIOS and entered those settings in EVGA Precision X but as soon as I load up a game (BF4), I get a display driver crash. So I assume I need to dial back some of those settings? If so, which ones and by how much? I need to know the relationship between settings so for example if I back the GPU clock down by 20MHz, what do I do to the others and vice versa?

Thanks

Overclocking, in general, goes like this:

1. Raise clock speed until unstable.
2. Raise voltage until stable.
3. Raise clock speed until unstable.
4. Raise voltage until unstable.
5. And so on, and so forth, until you've reached a point where the voltage becomes unsafe.

Keep in mind that memory and core (GPU) clocks have their own voltages. The voltage you have listed as +37mV is most likely the core (GPU) voltage. Also, remember that every chip is different. Someone with the same card may hit higher clocks than you; that's just the way the silicon lottery works.
