![]() If that doesn't completely fix the problem then try using a power limit of 85. Remember that It is necessary to run these nvidia-smi commands again after every reboot. So I would suggest enabling this underclock only when you're gaming. I looked up the likely reference clock rates for your video card at This is not a perfect replication of "Debug Mode" from the Windows nVidia Control Panel, because this locks your video card at the maximum reference clock rate. In Linux, if you can't find an equivalent feature in the nVidia settings UI, then you can replicate the feature with the nvidia-smi command, as follows. It is necessary to enable Debug Mode again after every reboot. There is very little change in the FPS as a result of enabling this, and a very big change in the reliability. This changes the clock rates to reference clock rates, and it limits the power level that the video card can operate at. In order to disable factory overclocking of your video card, you can enable "Debug Mode" in the nVidia Control Panel, at least in Windows. This was until I disabled the factory overclock and replaced the power supply with a good one, as explained earlier. It would happen even when using Firefox with = false in about:config. If it was set to 100 then FPS throttling was disabled.Īs time went on, my card got worse and worse with the black screen problem. Check how it's configured already before changing it, and please tell us. The equivalent user.cfg settings are as follows. Later, for testing purposes, in order to treat the symptoms of the problem, you can enable "FPS throttling in menus", as well as in games. of your video card with appropriate software. Also consider watching the clock rate, power consumption, etc. Then watch the FPS when the black screen problem occurs. Edit your user.cfg file (probably in ~/.config/0ad/config/user.cfg), and change or add the following line. You can run a simple test by monitoring the FPS when it's in the menu. This was also the most likely time that the factory-overclocked boost clock rates would be used. The fans would speed up, which was an indication that the graphics card was drawing a lot of power and generating a lot of heat. For example, the simple menu of many games would allow the graphics card to pump out several hundred FPS, maybe close to 1000 FPS. They're still available direct from .Ī pattern that I noticed with my video card, before I made the recommended changes to fix the problem, was that high FPS situations would make the black screen problem more likely to occur. ![]() ![]() The EVGA SuperNOVA G3 was the last series to use SuperFlower. EVGA sometimes rebrands Superflower power supplies. The Superflower OEM consistently has good power supplies. I recommend using a power supply that gets good reviews from or another review site that stress tests power supplies at high temperature and load, checks them with an oscilloscope, and disassembles them to check whether quality components were used and whether they have good design and soldering. I recommend the same steps that solved the problem in my case: disable factory overclocking of your video card, and if that doesn't resolve it then replace your power supply with a high quality power supply. So, one hypothesis to consider is the "black screen problem" that many factory-overclocked video cards have, especially as they age. When I temporarily re-enabled the factory overclock, the problem re-occurred only while the factory overclock was enabled. When I replaced the power supply and disabled factory overclocking, the problem was resolved. I tried many troubleshooting steps, including updating the drivers, reinstalling software and the OS, etc. Other times the screen would flicker black and then the game would crash to desktop, and a message about video driver recovery would appear. When playing any 3D game, sometimes the screen would flicker black and then return to normal, and sometimes the screen would stay black until I rebooted. Does this happen with other 3D games? My nVidia graphics card had a similar problem. ![]()
