The 680 is different generally speaking, since it has kepler throttle it can sense when things are about to go haywire and 90% of the time you will get a TDR instead of a BSOD or hard reset with the kepler when using an unstable OC. With reference 680s no matter how hard i pushed if the OC was unstable it would always end in a TDR with the 2d clocks reset to 384mhz or something......like I said the lightning with BIOS2 is different since it removes kepler throttle.

That said, the lightning BIOS2 does cause a hard reset with instability (due to no kepler throttle) but BIOS1 is TDR like most other 680s.

Call me crazy call me maybe....i was thinking what exactly causes these cards to crash? Overheating the vrm too much...im getting a 120+ offset for the core and 500+ offset on the memory with card and another card i can get past 1282 corr clock stable...havent touched the mem on that onr yet...why so different? I havent taken this particular card apart yet but what if all these lower oc cards are because maybe the heatsink or thermal pads or what have you is not seated as good as these higher oc cards? What if all it takes is a little extra TLC and maybe adding artic cooler or thermal pads yourself? This might sound crazy but call me maybe

So I guess kepler throttle isn't completely worthless, just 99% worthless tongue.gif That said, the lightning BIOS2 does cause a hard reset with instability (due to no kepler throttle) but BIOS1 is TDR like most other 680s. I theorize that this happens since the lightning does not have kepler throttle when using BIOS2.

So far we have not really an idea how to organize this but we will start with an important thing this evening: we will order the card so a block will be available

Sounds like water blocks are coming.

Some wierd activity to report here with the new card. I get the driver crash at 1270mhz core and also when I set it at 1300mhz. With my last card I got a hard reset even 1mhz over my stable clock, so, yeah and also I'm getting within the margin-of-error for 3dMark11 graphics score whether I have the memory at 6400mhz or 6800mhz. I know memory makes more of a difference than that, and Afterburner is definitely reporting a stable 6800mhz memory clock during the test. GPU score @ 1260/6400= 11,376.....@ 1260/6600= 11,376 (yes I actually scored the exact same with the second run.....@ 1260/6800= 11,441. This card acting wierd?

I've tried 304.48 and 304.79 drivers, and the card is definitely in the LN2 BIOS.

Peculiar indeed, never had a driver crash in my limited testing with 2 different lightnings. Does this occur at stock memory clocks?

Sounds like a junk overclocker, sorry you didnt get one like you had before.

Yeah it doesn't appear to be a worthy replacement. But the driver crashing seems wierd instead of hard resets. And the 400mhz+ memory overclock should have at least some affect on scores headscratch.gif
