Overclocking 8800 gtx

[Salome]

Hi!

These days I tried to get the most out of the 8800gtx in OC. Turning the Atitool for half an hour I was stable core of 661, 1688 and 1030 of shaders memory.The temperature rises of non-idol not GPU rises of 61 º C at full load. Using an Arctic Cooling accelerator Xtreme (p *** is with onion) xD

Well, the topic, I wonder if I can raise even more because when core passage of 661 core (pongo 663) and I hung. It seems that there is some sort of limit or something. Lu good news is that I can put 673 of core and I get to play Crysis for 10 minutes, but then hangs. Like the shaders, its border with my 8800gtx is 1699, and then hangs.
He Lei voltage but something is dangerous, right? I have also seen some flashing to be an ultra.
This chart gives me too because I believe, but even so, for trying, I'd like to play a little more.

Thank you Very Happy

Not much more without getting in Vmods.

Skip to Ultra is nothing more than make a BIOS with the values of the clock and then flashed Ultra, which do not need because the pass (at least memos) with your OC.

Have you tried to leave the shaders a lower core and continue to rise?

Now what I try about 3 times.I downloaded the shaders until 1550, 1500 and in default. But nothing, hangs going from 661.
Can we raise more with what I said has Vmods? Would there be much risk? How could it do?
I love the risk
