Ronan I use LN2 exclusively on my Lightning cards so my outcomes are not representative at all. However I have just received an addition two cards and they still have the coolers on so I can have a quick check for you. About to put a RIVE system up to test a problem for a user so it sort of all fits in. You just interested in max overclock on air, Vantage stable ok?
When testing other reference PCB cards I only had 2 that would not run 1300MHz Vantage and Unigene stable. I did have a modified bios that allowed some headroom with respect to voltage. That was on the stock air coolers. All those cards maxed out at 1480Mhz give or take a MHz on LN2.
Edit. That was without any volt mods at all. VRM where what held me back I am sure. Killed two cards just fining the max I could do. Then did the volt mods on the reference cards and killed two more. Simply gave up with the 680 reference cards thereafter. Plus the Turbo boost thing is a pain for clocking.
Might take a while to get the RIVE rig set up, looking for a spare mounting bracket for the CPU cooler.
😛 Do not want to break down my other rig I am benching on but I know I have a second bracket some place, at least I had one before the school holidays started and my two have been playing downstairs.
