Poor clocking Lightnings or just people that don't know what they are doing with them? Granted on air they aren't going to be smashing any records, but then again for overclocking, these cards aren't aimed at air cooling. From what I've seen the average core speed on a watercooled Lightning is 1320 - 1360mhz, at that point you hit a voltage barrier, I have seen the odd one drop out under 1250mhz, but those were on air.
I'm not saying your wrong, or what you have read is wrong but from what I have seen you are, on average, more likely to get a good overclock from a Lightning 7970, only time will really tell if the BE is merely a vBIOS update or not, I'm not at all convinced by the claims these 'GHZ' cards have better yields or whatever to give clock headroom.
I couldn't agree more about the DVI ports however, if it truly is a 'revised' card then surely MSI would have sorted something out in that area.
1350/1950 for now, any more on the memory I get memory correction kicking in, as soon as I find what dark dirty method I need to raise the voltage I will be aiming for 1400/1950 @1.4v for some bench runs.
Hmm, perhaps. It just seems strange the Lightning 680s can hit over 1300s a lot (on air from what I hear). Yeah, different architecture, I know, but the AMD's are supposed to be pretty good for OCing.
