getting coolbits to work on linux does require some legwork but it does work headless at least on driver version 346.59 + Cuda 6.5
I just ran 2x Gigabyte WF GTX 750ti cards to their max on lyra2v2. I can't get much past 1358 MHZ core clock and +100 MHz mem clock without them crashing on Win 10: 32 bit, Release 66. Best I could do was 4900 kH/s. Once I start actively using the computer, the card that displays on the monitor crashes.
If you want to clock higher you need to modify the tdp in the bios from 38W to 63W. And you probobly need powered risers/or cards with a 6pin power / or motherboards with extra power.
I had one ETH mining rig with 3x750ti. With ubuntu 14.04, cuda 7.0 or 7.5 and 35?. drivers overclocking was easily done. Genoil cudaminer thread where I found all the info I needed.
Hashbrown, you have 32-bit W10? Or 32-bit ccminer?
