Asus GTX460ENG Direct CU overclocks

I picked up one of these 1GB cards from newegg a couple weeks ago and am going to start playing with overclocking it. The overclocking tool has voltage adjustments as well as engine and memory adjustments. I think its defaulted to 1.2 volts, 675 engine, and 3600 memory.

I pushed the voltage up to 1.5 and upped the engine to 800 last night and ran through a couple Heaven benchmark tests. It was noticeably faster than stock and the results showed it.

My question is, has anyone else on this board played with their card to see what decent settings would be? I'm unsure what I should be using for voltage maximums, engine, and memory. I've seen some people say their engine can do 900+ and memory 4000, but I'd like to get an overall feel of what others are happy with. I wasn't planning on buying a larger monitor when I got this card, but now that I game at 1920x1600, this card may be a little underpowered.

I'm totally bamfoozled here...no GTX460, even stock OC'ed ones, should be defaulting to 1.2V out of the box, let alone survive being pushed to 1.5V on anything short of LN2 cooling.

What am I missing?

maybe 1.02 and 1.05?

Sorry, yes, 1.02 and 1.05. I was going by (faulty) memory. I raised it to 1.05 volts to get those results--maybe it would have been fine at 1.02 volts. I can't really see .03 of a volt having that huge of a difference, but with fine electronics, I spose it does. It's not an open box model, it was new sealed.

What is a open box model? mabe you got someone elses card that unlocked the voltage in the bios?

Err, what? Its not an open box model, the direct cu are set up in the bios to allow for voltage and mem/core tweaks using the asus tool.
 
850mhz core is about equal to a gtx 470. If you could get 880-900mhz that would be awesome. From what I've read overclocking the memory doesn't do much.

Still at 1.05 volts. I'm up to 820 engine so far without any issues. No sparklies, corruption, or anything else, and yeah, the gameplay is very noticeably smoother than the 675 I started out at.

I will try to go higher later.
 
I am using EVGA precision to monitor and up the shader clock to 1675 which in turn increased the core clock to 837 on each of my GTX 460('s) SE 1GB. Been F@H for about a week now without a glitch. Temps around 57-65c. I dont even mess with the voltages.
