fermi memory voltage tolerance

[exaberries]

So I finally got a 560 ti modded for both core and mem, cap mods, delided, and on an aio and before running any benchmarks I raised memory voltage above 1.7 volts (I don't know exactly what it hit) and had immediate shutoff followed by artifacting and inability to get into windows outside of safe mode. The Elpida datasheets suggests that the gddr5 should tolerate 2v. Its possible that I passed this point but i'm thinking that its more likely the memory controller. At least I already had ordered another 560ti (hopefully without elpida this time).

I'm hoping that somene with more experience with this can shed some light on safe memory voltages for fermi cards.

I'll post a full rundown of the mods soon.

What is stock ram voltage though?

Normal practice is to raise it a bit at a time to check scaling, as that way you can stop when either scaling turns negative or you have reached a maximum clock.

Default was 1.35 I think. I was trying to see how quickly the voltage rised when turning the pot to see what the non linear behavior was like.
