I run my 4gb 470s at a high mem overclock (1950-2000) and a big core (+ mem controller) undervolt (850-875mv). Core around 1060-1080.
As I was pushing the mem OC and undervolts, the system became more unstable the farther i went.
I seemed to notice that setting the primary display 470 (whichever is in the main pcie x16 slot) to less of an overclock and undervolt, the stability may have increased.
For example: my primary display 470 is clocked at about:
1060/875mv 1950/875mv
while the rest of the 470s are clocked at about:
1080/850mv 1975-2000/850mv
This may or may not help some of you further optimize. If you experience this same phenomenon, I'd appreciate a post here so we know it may be more likely that this is the case.
