My guess yes, I think there's a fair few people on here that do it on air. Pretty sure its mostly covered in the OP.

Will probably have some effect on the lifespan of your 780, but they're supposed to work well past their warranty. Should happily run 1.212v unless you have really bad case airflow or you intend to keep your 780 until 2024.

Just picked up my new Classy. I got them to pricematch amazon (I didn't know they did that, I just asked) so I got it for $30 more than the SC. Nice trade up. Should last me a good while.

Edit: also get a $20 mail in rebate on top of it. Ha!

Awesome, man! You made the right choice. For $30 it's a no brainer. You will really like the Classified. What are your plans for it? Air? Water? LN2? biggrin.gif

I've got mine on air but I'm thinking of making a custom loop.

I'll stick to the ACX on air for awhile. What's a good OC to shoot for on it through that?

For benching, as high as you can get!

For gaming I run the stock boost BIOS with 1,200MHz on both cards at stock voltage and no memory overclock. On air stay at or below 1.25v and keep watch on your core and VRM temps. The higher the voltage goes, generally the less stable you'll be at the same temperature vs. running a lower voltage. For single card 24/7 you're probably going to end up somewhere between 1260 and 1306. That's just a guess, more research required.

I'm running a custom fan curve I created in Precision X for gaming.

Yeah, I may try that later; but I would just like the card to function normally the way I bought it :/. I'm sure some of you may be ok overvolting from the getgo, but it's nice to know something you spend $500+ on works like it should.
If the fresh inatall don't work contact EVGA, they have great customer service! when I bought my gtx760 ftw I was having driver crashes and for about a week and a half I tried troubleshooting on my own, doing everything I could possibly think of and finally decided to contact evga and they had me try a few things (that I already tried) then said it needed replaced! don't seem like you should have trouble getting it running without crashing, thumb.gif

Yeah; I'm just hoping I don't. It sucks to get a new toy and to have to ship it out, then wait for it to come back, etc. It's not their CS I'm worried about, so much as I just wanna play with my new toy redface.gif. This actually my first 'flagship-tier' card that I've ever bought new tongue.gif. I had a HD4870 once upon a time, but I didn't buy it new tongue.gif.

That's impressive! Hopefully I can get my card to 1300, that would be killer.

Stock boost bios would be switching the bios switch to red, correct? I have never owned a dual bios card.

Both the Normal and LN2 BIOSes that come with the card are "boost" BIOSes. There is a set clock (you can see in GPU-Z) of 993MHz, but the cards will boost under load to usually around 1123 or 1136 depending on the card.

I left my "Normal" BIOS alone and it's the one I run most of the time. I replaced the stock LN2 boost BIOS with skyn3t Rev.3 BIOS (boost disabled). Boost can be unpredictable so OCing and benching with a non-boost BIOS is easier than with the stock boost BIOS. skyn3t also increased the power target, increased the stock clock, and increased the voltage a tad.
