GTX580: 1.025VID: 950/1900/2300: stock cooler: guaranteed?!?

[Demo]

Alright, How about GDDR5 stability, I heard these things auto downclock if it goes to high.. would 2200Mhz on a GTX580 be like 100% attainable ?

EDIT:

Looks like ambush is not even able to maintain a constant 90% GPU usage, probably its my Q6600 @ 3.4Ghz thats being a bottleneck to the GPU.

EDIT2:

So today I was just stability testing on my GTX580 its been running at 900Mhz core for quite some time at stock VID of 1.088 and on my first run on heaven 2.5 I got a red colored lens flare rendering glitch, which I fails to repeat it self after i tried 10 more loops. Stability testing on videocard OC's are quite unsatisfying (haha!) using 1.1v is too much for me just to get 900Mhz core, maybe ill just dial down to 850Mhz core and undervolt my GPU.

I wonder how nvidia/evga came up to binning this chip at 1.088v, I mean if the chip can do 1.025v with 850Mhz core why is it binned at 1.088v
