Gains from memory overclocks vary a lot. I found with my 780 that about +400 (398 or 396 actual can't remember which) is as far as I can push it if I want a good core overclock - it will go beyond that stable with mild core overclocks but I can't get higher core frequencies stable that I could with upto +400 on the mem.
 
How do you guys check you gpu voltage?
The readings on hwmonitor are .850v idle and .9v under load so I have a feeling that it's not accurate.
I've got msi afterburner and precision x but I cant seem to find it anywhere
 
in Afterburner my gpu voltage shows in the graph section if your's doesn't try scrolling the graphs down or download the beta 18 version iirc its the latest
 
Skynet bios is failing me, though it might be down to using a super jetstream bios on my phantoms, tried to bench catzilla at 1100/6400 which is near enough my stock bios clocks and it failed hard :(

BF4 on siege of shanghai ultra settings is quite a good test for memory clocks. I'd be surprised if you don't see artifacts after 10-20 mins at that oc.

I doubt it would yield much gaming performance..who knows but I only tested it on valley benchmark just to see how far it could go.. went up in 100s each time

when doing 1k i saw artifacts otherwise all the rest was crystal clear
