I have the same issue as 5w00p on both 750ti's (Asus and Palit). PSU 1000W. The same on Quark and x11, on ccminer-1.6.2-git-tpruvot too,
but on dmd-gr algo all ok!
I think the code has drastically changed regarding the load/power consumption factors....Here are my observations about it:
- I always run binary releases from sp directly,
- on quark my miner of choice was old sp mod 3.1 release,
- have 1 comp for testing and two rigs 6x750 ti gigabytes all OC,
- 3.1 release gave me best hashrate until latest release 4.6 which gave significant boost,
- look at graph recorded with nvidia inspector, running different miners on same machine,
- each miner was running quark for about one minute,...didn't count exactly
- but pay attention to gpu load/power consumption:
gifs upload- see how the graph on 3.1 miner is almost flat!...while newest release (4.6) is quite an improvement regarding the older (4.4)
