On water my galaxy reference card is set to:
1.087v
776 core
1552 shader
1823 memory
This is stable for me and put in about 70 hours in new vegas which is just awesome by the way, and didn't have any artifacting, just normal game crashes because of the engine. The card doesn't get above 50c and my water temp usually teeters around 32-35c. I guess that's good. I'm sure I can volt the card more to get higher clocks, but I don't really see the benefit, this card seems like just an ok oc'er.

I must have a pretty good example then. It is an MSI N470GTX-M2D12-B
With stock air cooler, 1.087V 850-875 core, 1700-1750 shader (depending on room temperature, more on cooler days, especially if I open the window) and 2000 (4000) Ram...
I played S.T.A.L.K.E.R. Shadow of Chernobyl at 1920x1200, everything maxxed, 16X AF, and 8XMSAA for almost 40 hours without any artifacting or a crash. This gave me min framerates of ~40fps. Temps were a little on the high side at the low to mid 80s, but I am not concerned, as maz temp appears to be 100C or above...
His is probably OCCT Error Check stable.
That's basically what I did, though I used ati-tool. Is there another one out there which works slightly better?
OCCT Error Check Is the best and most thorough way to test GPU stability
Speaking of OCCT when I ran the damn thing my UPS alarm went off. Pulling to much voltage I would assume.

Hmmm, so long as you've got the latest afterburner and the "Unlock Voltage Control" box is checked and restarted Afterburner, it should work and give you access to move the core voltage slider across and apply.
Should look like this, but you may as well tick the start with windows and minimised.
If you're still having problems it may be the card BIOS.
Rossi your afterburner is out dated
you're missing the force constant voltage option.
Are we supposed to be using the "Force Constant Voltage" option?
is MSI afterburner a bad tool to use on an asus board?
There is no point in forcing constant voltage other than wasting power.
When i did the OCCT test. it had my GPU @ 0.71V instead of 1.037v(current setting in afterburner)
why is that?
Welcome to my world.
As a little safety feature the card will clock down (as well as voltage) when the card either becomes unstable or too hot. This could be the issue you're having. I'd run OCCT Error Check or play WoW for a while with the card at stock clocks just to verify this.

I wouldn't consider overclocking a GTX470 using a 520W PSU... It may be your problem there dude, the GTX470 & 480 both drink 12v by the gallon load when overclocked and that PSU has 480W available on 12v. What's the rest of your rig specs?
please don't go cheap on psu
