At what speed we can expect GTX Titan to run any CUDA software under Linux: 836, 876 or 973 Mhz?
It seems that by default (80C target) the Titan runs under Windows mainly on the maximal core speed (around 1 GHz) not the boost one. It goes back to 836 only if the temperature rises above 80C.
Does Nvidia support boost 1.0 and/or boost 2.0 technologies under Linux?
I asked the same question in Linux category and Amber 12 developers (the CUDA software that I use under Linux), but they don’t know too and will ask Nvidia. Moreover, it seems that nobody knows is the boost speed of all GTX6xx series is supported under Linux? Further it is not clear why when you make query for your device you obtain:
|------------------- GPU DEVICE INFO --------------------
| CUDA Capable Devices Detected: 1
| CUDA Device ID in use: 0
| CUDA Device Name: GeForce GTX 680
| CUDA Device Global Mem Size: 2047 MB
| CUDA Device Num Multiprocessors: 8
| CUDA Device Core Freq: 0.71 GHz
Please share some experience with GTX6xx cards and boost technology in terms of CUDA calculations and performance under Linux. For instance, how we can see at what actual speed GTX680 runs some CUDA program under Linux?
EDIT: The topic should be actually “The clock speed of GTX Titan for CUDA calculations”,sorry for that but I am not able to correct the title anymore…:(
