K-boost. Is it safe?

post #1 of 11
Thread Starter 
I'm running to bios modded 670 windforce x3's at 1241mhz but in guild wars 2 my gpus always downclock in high cpu situations and i found with enabling k boost they dont downclock.

Will k boost lower the lifespan of my gpus?


Also another question, when i had k boost off i would boot into a game and one card would be at 1241mhz 1.175v, second card at 1.87v 1241mhz but eventually the 1.175v card would go to 1254mhz and 1.87v when i already had it set at 1241mhz 1.87v. this is an issue because at 1254v it crashes and i can't get the clocks to sinc, it does this at any clock, it eventually increases after 30minutes. i've even reflashed bios.

are you sure about that 1.87v? that is abnormally high and shouldn't be possible.

I have a 690 and the max voltage I see on either of my gpu's is 1.175v

K-boost is pretty much useless. All it does is lock your card at boost clock and voltage permanently, even in 2D mode. Don't use it, all it does is lower the lifespan of your card, use excess power and create more heat.

you can unlock your voltage and to the post below, the thing is...without k boost on..in guild wars 2 my gpu clocks drop from 1241mhz to 980mhz in high cpu scenarios

My GPU core clock drops all the time but it doesn't matter because I'm still maintaining 60 fps?

when my gpu core clock fluctuates the fps changes a bit causing the camera screen in the game to jitter when turning, with k boost on problem is solved. i also run 120hz so i try to get 120 fps

I hope you're keeping an eye on GPU temps. The GPU is lowering clock speed to keep it's TDP and/or temps under the maximum limit. K-Boost is basically disabling the safety features on your GPU, so YOU are now responsible for monitoring and keeping temps under control.

Personally, I don't think it's safe for long-term use.

the temps are about 50c when its downclocking in guild wars 2.

K-Boost can help to keep the clock from dropping in some applications, particularly legacy.

We are not aware of any decreased lifespans in cards by using this.

BTW the next version of Precision will allow you to enable/disable K-Boost without reboot.

Wow, awesome. Always found it annoying having to restart to enable/disable it. You know what would great, if k-boost could automatically enable when games or gpu intensive applications are running. Maybe implement it in a way like "Nvidia Control Panel" allows you to apply certain features to games under "Manage 3D Settings"
