A minor hassle for me is that the i7 K and X series don't have on-board video, and I've already given my older card to a young relative for whom it's a bit of an upgrade. So I'll have to order a replacement and wait for it to arrive before sending the first one back for a refund.
I find it hard to believe that MSI allowed this GPU to leave the plant on a Lightning. It should have gone into a lower-spec model. I imagine that it passed whatever synthetic tests they have, with absolutely no OC headroom whatsoever, and they thought that was good enough for a Lightning. But we all know that games can at times throw so much at one's system, they can be a harder test (although the torture is not sustained as in a synthetic), so headroom is essential.
I'll report back when the new card arrives and I have a chance to evaluate it. Thanks again.
It's definitely an amazing card, you were just extremely unlucky. Well, not as unlucky as you could've been if it ran fine on the stock clocks but wouldn't take a 20mhz OC. MSI only tests for 1202mhz, so they have no knowledge of a card that overclocks to 1350mhz on the stock voltage any more than they know about one that won't even take 20mhz. It's all the luck of the draw unfortunately. But it's good that yours crashes, that means you can RMA and get a better one. Not being able to overclock 20mhz isn't a valid RMA reason unfortunately, but crashing on the stock settings is. You'll be glad you waited and got a new one.

At one point I was also getting worse performance when I was overclock so I backed it down to what my max stable was before the art money hack which is 1398mhz and +400 on the mem. That gives me like a score of 1422 maxed out in heaven.
+200mv? Yeah that's going a little high I would think. Unless it's winter by you or something where you can keep temps low enough.
You're not using the LN2 BIOS for benching? +100mv should've gotten you to 1.36v (actual, not according to Afterburner). Maybe you were getting a worse score because you were throttling because of the Power and temperature limits?
Edit: Yeah I just noticed you said you were throttling. Yeah use the 3A LN2 BIOS and you'll have some better luck. Just remember it's about 50mv higher at any given offset than the non-LN2 BIOS. So I wouldn't go jumping right into +200mv without being sure about temps.Edited by dph314 - 2/9/13 at 8:32am
