Between the two I would have gotten the lightning and gotten some mDP cables. That said I wouldn't trade my quad cherry reference cards, heck no.

hmm I did a LOT of research...apparently the non top version is hardware voltage locked.

The top version is usually not voltage locked but a few have been software voltage locked and people have managed with software to unlock the voltage.

I'm not sure I would've chosen an inferior card if I could just get a cheap 6 dollar cable........


And No, you're wrong about the BIOS, PLENTY of 7970 DC2T owners have said their cards are voltage locked and there are quite a few issues with them. While their have been also a few DC2T owners that have had their cards work 100% and have been unlocked I would say at best it seems like a 50/50 shot.


I wouldn't take that risk if I could get a MSI lightning and a cheap cable and be more than happy.

Like I said not all are locked but the TOP have been OOS for a couple of months in some parts and there is a pretty bleak thread in the ROG forums about the DC2T and it's many issues..........

bleh card is on its way!..............I did do research...from what i read from multiple sources the 7970 TOP is NOT hardware voltage locked and the very worst it will be software voltage locked. I will keep this thread updated.....if its crap will return it!

Yours is the 7950 DCii so im not sure.

They probably locked the 7970 DCii non top so that there would be a difference between the two...otherwise its pointless to get a "top" card when anyone can just ramp the MHZ up by 75......but I hope im right and I have no issues.............lets see if my lazyness to get a display port pays off or not:D

Good luck with your card man! I only know so much about it because I myself should be getting one this week so I have all the negative threads and posts about the card in my head..... tongue.gif

I'll have not only voltage to hope for but also that my DVI dual liknk works properly for my monitor as even that's a 50/50. tongue.gif

Anyways, I'll hope for the best for your card and my own!
