EVGA GTX480 + Arctic Cooling Accelero Twin Turbo II Cooler = OC

Hi,

I have a EVGA GTX480 (the latest, 015-P3-1480-KR) and I've bought the "Arctic Cooling Accelero Twin Turbo II" cooler to it.
I did it first just because of the noise. The rest of my rig is virtually silent and the GPU itself was the noisiest component.

But I need to admit that I am IMPRESSED by this cooler.
Previously, my IDLE temp was about 45-50C (this WITH High-Flow Bracket) and with just some minutes of FurMark (like less then 10min) I used to reach 85-95C easily with no OC and with the stock cooler SCREAMING like a JET (95%+)!
Now, my IDLE with this cooler on minimum speed (30%) is like 35-40C and completely silent and under FurMark it NEVER passes 75C with the fan at 80% speed MAX, with very low noise.

So, now I am (of course) playing with OC on it :D 

So, I've reach this config here completely stable (FurMark stable under 80C or less):
1.1V, Core 900MHz, Shader 1800MHz, Memory 2100MHz.

My questions are:

1) This config is safe?
2) Can I go higher?

Thanks! :D

I don't see why not, the gtx 480 can handle temps of around 100C.

I am more "concerned" with the memory because I don't know if that "temp" just shows CPU temp.
Since the new cooler just have "heatsinks" on the memories, I am concerned to overclock the memories too much...

Tip about gpu overclocking, don't worry about memory just nuke the core/shaders.

Really? But do you think that I can keep the memory stock clock and OC the core/shaders like hell? This will not create "weird behavior" / "artifacts"?

Usually, overclocking memory creates all of those weird artifacts, so I would only oc shader/core.

Cool! Nice to know. I will try it.

Just for the record, I've created an "underclock profile" just to keep my board cool / silent when I am NOT gaming and it is AWESOME. Totally silent and the power consumption drops A LOT! Here it is: 825mv / 405MHz Core / 810MHz Shader / 920MHz Memory / 30% Cooler.

The card will underclock itself when you don't do anything, all I would do now is just create a custom fan profile.

Really? But it will also undervolt? My concern was basically reduce power consumption so I can keep my rig "on" doing "simple folding".

Yes, it will do all of that :)
