Before using these newer drivers, the Performance Level would only increase when it was really required 3.D rendering, HD video playback, et cetera.I probably wouldnt have even noticed that the Performance Level was changing, except that it would cause the GPU fan to spin faster, which was noticeably louder in my office.After scouring the interwebs, I found that I was not the only person to have this problem.For reference, see this article, and this one about locking to certain Performance Levels.However, I wasnt able to find a solution for the exact problem that I was having.If you look at the screenshot below, youll see that the Performance Level is set at 2 which was causing the card to run quite hot 7.C even when it wasnt being pushed.Click to enlarge.It turns out that I needed to add some options to my X Server Configuration.Unfortunately, I was originally making changes in etcX1.I added the following lines to etcX1.Section DeviceIdentifier Device 0Driver nvidiaVendor.Name NVIDIA CorporationBoard.Name Ge. Force GTX 4.Option Registry.Dwords Power. Mizer.Enable0x. 1 Power.Mizer. Default. AC0x.End. Section. The portion in bold the Registry.Dwords option was what ultimately fixed the problem for me.More information about the NVIDIA drivers can be found in their README and Installation Guide, and in particular, these settings are described on the X configuration options page.The Power. Mizer.Default. AC setting may seem like it is for laptops that are plugged in to AC power, but as this system was a desktop, I found that it was always seen as being plugged in to AC power.As you can see from the screenshots below, these settings did indeed fix the Power.Mizer Performance Levels and subsequent temperatures for me Click to enlarge.Whilst I was adding X configuration options, I also noticed that Coolbits search for Coolbits on that page were supported with the Linux driver.Heres the excerpt about Coolbits for version 3.NVIDIA Linux driver Option Coolbits integerEnables various unsupported features, such as support for GPU clock manipulation in the NV CONTROL X extension.This option accepts a bit mask of features to enable.WARNING this may cause system damage and void warranties.This utility can run your computer system out of the manufacturers design specifications, including, but not limited to higher system voltages, above normal temperatures, excessive frequencies, and changes to BIOS that may corrupt the BIOS.Your computers operating system may hang and result in data loss or corrupted images.Depending on the manufacturer of your computer system, the computer system, hardware and software warranties may be voided, and you may not receive any further manufacturer support.NVIDIA does not provide customer service support for the Coolbits option.It is for these reasons that absolutely no warranty or guarantee is either express or implied.Before enabling and using, you should determine the suitability of the utility for your intended use, and you shall assume all responsibility in connection therewith.When 2 Bit 1 is set in the Coolbits option value, the NVIDIA driver will attempt to initialize SLI when using GPUs with different amounts of video memory.When 4 Bit 2 is set in the Coolbits option value, the nvidia settings Thermal Monitor page will allow configuration of GPU fan speed, on graphics boards with programmable fan capability. Cheap Free Mp3 Music Download Waptrick For Pc . When 8 Bit 3 is set in the Coolbits option value, the Power.Mizer page in the nvidia settings control panel will display a table that allows setting per clock domain and per performance level offsets to apply to clock values.This is allowed on certain Ge.Force GPUs. Not all clock domains or performance levels may be modified.When 1. 6 Bit 4 is set in the Coolbits option value, the nvidia settings command line interface allows setting GPU overvoltage.This is allowed on certain Ge.Force GPUs. When this option is set for an X screen, it will be applied to all X screens running on the same GPU.The default for this option is 0 unsupported features are disabled.I found that I would personally like to have the options enabled by 4 and 8, and that one can combine Coolbits by simply adding them together.For instance, the ones I wanted 4 and 8 added up to 1.I put in my configuration Section DeviceIdentifier Device 0Driver nvidiaVendor.Name NVIDIA CorporationBoard.Name Ge. Force GTX 4.Option Coolbits 1.Option Registry.Dwords Power. Mizer.Enable0x. 1 Power.Mizer. Default. AC0x.End. Sectionand that resulted in the following options being available within the nvidia settings utility Click to enlarge.Though the Coolbits portions arent required to fix the problems that I was having, I find them to be helpful for maintenance tasks and configurations.I hope, if youre having problems with the NVIDIA drivers, that these instructions help give you a better understanding of how to workaround any issues you may face.Feel free to comment if you have any questions, and well see if we can work through them.
