Impossible to tell from a distance. You could use an IR thermometer to check for a bad connection in the future. A high resistance connection will get excessively hot under load. 70 - 80+ C at a connector, is probably an indicator something isn't quite right.

I have been using the SC BIOS for slightly over a year now. I run the max 1.212 voltage. Got 3 Titans in SLI overclocked to 1110 for gaming with mem set to +200. No problems at all. Tested stability for about 10 min with OCCTPT once. The PC was pulling 1472W according to my power meter. I do not run any mining software however. I think it is more likely that the connector fried due to a bad/high resistance connection, than due to a BIOS problem.

Easiest way to run the below file is to disable SLI, right click it, select Run as administrator and reboot: Geforce 600 Series Gen3 Support On X79 Platform

You can ignore the Valley reading. It's erroneous.

Sounds like there might be some kind of bottleneck in his system. The base score for WEI is always the lowest number.

Try resetting the CMOS of your mobo. If that doesn't work, place the one that's not detected in the first suitable PCIe slot in single card configuration. Reset CMOS again if necessary. If that works verify with the other card whether it's not a problem with your PCIe slot.

Sometimes, overclocks can be too close to the bleeding edge. Without any breathing room to compensate, a different driver or BIOS may push your hardware too far. In my opinion, for everyday use, it's better to back off one or two notches from your max achievable. I do the same with my CPU and rarely experience issues with software or firmware updates.

Just to elaborate, I'm running 3-Way SLI water cooled. The cards don't even reach 40C during gaming with an ambient of 23C. Clocks so far are set to 1150 and mem to +300 on all cards. Sync between cards is off. In Crysis 3 single player when running 1920 x 1080 @ 130Hz with all details set to max, no motion blur, no Vsync, no AA or only FXAA, one or more of my cards will clock down to 1019MHz or something less. As soon as I set a higher AA or run the game on higher resolution monitor at 2560 x 1600 the cards will be at full clocks again. I'll try more games once I get my system sorted out and stuff installed. No need to change anything though. From what I've seen the BIOS works fine as it is.

I just finished rebuilding my PC yesterday. After verifying everything was running properly I flashed my cards with the modified SC BIOS from here. Finally the clocks make sense again. Just like with previous generation cards before Kepler, they now logically increase with added increments of a GPU overclock. You no longer have to test and guess where the max GPU clock will eventually end up while boosting. Saves a lot of hassle and time. Very nice! Another thing I noticed was that the GPU still down-clocks or throttles. Initially, I was a little disappointed, because it appeared there wasn't _that_ much of a difference compared to the original BIOS. However, after further testing I found out it was due to the simple fact that the GPU didn't have enough workload. As soon as I cranked up the AA I got full boost again. Not sure whether this is an intended feature, but it's a good thing. No point in running full clocks when the utilization is only ~35% and totally CPU bound. In that respect it works a little like the original BIOS and not completely wasting energy by just generating heat. Very nice again. Thanks svl7 for making this available!

The voltage adjustment with Precision does indeed appear to be a little flaky. In order to fix it sometimes you have to clean install the utility. I've also found that it helps to apply the voltage adjustment just before saving a profile. With some messing around it should eventually take even after a reboot.

On page 3 of this thread you can read that svl7 recommends using Nvidia Inspector instead of RivaTuner derivatives such as AB and Precision. Maybe try that and report back, Sorry that I can't help directly. I'm still in the middle of redoing my rig

Using the stock BIOS I've only went up to 1176 with my Titans on air (haven't tried mod yet). When I did the same on water I didn't notice a difference with the same settings and they're running at around 42C during high load. I'm guessing it's cause I hit the 106% power limit before temperature ever became a problem. Modern air cooling has come a long way. It's really good now. With water you don't gain much extra performance nowadays, but you can on the other hand achieve a much higher degree of silence. My system for instance runs the fans at 400 RPM during idle and only have to ramp up to around 700-800 RPM under load (@23-24 ambient). The problem now becomes the damn PSU fan, that makes the most sound. So now I'm in the process of upgrading to a 1500W from a 1200W. It should allow the built-in fan to remain in the silent part of the regulation curve.

I don't think there's much else you can do besides turning all your settings down and optimizing your cfg file. Overclocking a video card will only marginally improve frame rates, when a video card is already too slow in general. I'm afraid it's new card time if you're looking for a real boost.

From what I've seen there aren't that many dramatic price drops in a non-competitive market. The old versions are simply phased out and are replaced by new ones with a similar or higher price.

I have two Seasonic X-1250 power supplies. Both make noise depending on the type of load. Nothing I'm able to hear though, unless I put my ear right next to them. On occasion my GPUs whine quite a bit louder.
