quark is faster on the 750ti as well. (from release 57 to 58 on One of my test rigs the gain is 70khash per card.)
The current default intensity for the gtx750ti is
-i 5 and for compute 5.2 -i 22
Please help me find the best intensity settings people

Hi sp_, i am testing your new 1558 version, here are my QUARK results:
rig: AM1M motherboard with APU 5350 (25W TDP) 3x gigabyte GTX 970 G1 stock speeds, 14.04 LTS (flash drive), cuda 6.5.19 drv 346.59
default intensity is best BY FAR!, so you NAILED IT

I tested intensities from 20 to 24, all gives me at least 500Kh less, per card, than default.
at intensity 20 is when weird things starts to happen, power consumption SKYROCKETED!, from 650W to 780W

WTF!
at intensity 20 and 21 memory usage reported by nvidia-smi is about 200Mib which is very odd!, at default intensity (not specifiying it) i get 1433 Mib usage per card, at intensities of 23 and 24 memory usage drops again but to 650Mib per card.
at 23 and 24 speed reduces from 16400 per card to around 14000.
another weird thing is that, if i specify -i 22 i get about 500kh less per card than if i don't specify anything, and the memory usage also drops from 1433 to 650Mib.
also at default intensity i get the usual spiky power consumption behavior always had with the GTX 970 about one tick every 800ms, but at lower intensities the power consumption is more constant. (I have a bar graph (vu meter like) power meter i made to track things like this

i can do a video of different intensities and power consumption behavior if you like).
Rig: AM1M motherboard with APU 5350 (25 TDP) 3x Gigabyte 750Ti stock speed 14.04LTS (flash drive), cuda 6.5.19 drv 346.59
I found no difference with previous release 1557 in performance and power usage.
if you need me to test something, let me know, happy to help.
