This is the best release so far. Single thread on 750Ti is rock solid at 6766 kh/s [quark], showing the same and higher accepted hashrate stats on westhash. With -g 4 -i 22 comes close to single thread performance but not consistent.

wow - you are getting almost 1MH per card more than we are ... on stock clocks? ... how? ...

#crysx

I think with moded bios, i moded my asus's bios too, but power comsp. increase %10-15,about hashrate just increase the %3-4 .I decided to return stock bios. 1400 core clock gives 6600 on quark

well that explains it then ...

Are your 750ti's stable at 1404 boost ..I mean do you have any crashes at all? Mine love 1350 boost that's their sweet spot.

Yeah it's stable. Will crash if +10 more on the core. So its the limit for mine.

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)

Yeah, when I start quark mining with -g my speed is less (28M for 2x970), compared to 31M when starting without any settings (only -r and -R). release 46

Thats why I never ues those settings ...I just overclock.

(~42C was mining XMR, quark algo pushing the temp to ~50C)
I am getting ~15Mh/sec reported mining quark algo with release 44 on GTX 970 @ 1496MHz/3505Mhz gpu/mem.
No parameters set.

Did you try the 3 exe files in the archieve(release 46)?

ccminer50.exe
ccminer52.exe
ccminer.exe

ccminer52.exe should be best for your card.

Release 46 doesn't perform well on my machine, (GTX 970 / Win 8.1 x64) mining Quark algo, no settings.

The power consumption is a sawtooth waveform. It loads the card to ~120% (overclocked) and then down to basically 0%. Over and over. Up down, up down, up down.

Mining XMR the power consumption might fluctuate a little, and might not load all the way near 100%, but it is at least never below 60%.

I don't know why this happens and I know sp_ works hard on it and most you guys are on linux, but it sucks for me.

You lowered the power limit back to 100%?

Valid suggestions.

Tried the lowered clocks. No difference.

Release 44 works perfectly. But 45 and 46 just plain suck on my machine.

I should tell you that the PSU is fine. I have even given the GPU it's own 550W PSU.
And the GPU is watercooled. Doesn't go over ~42C under load.

Good suggestions, but I should note that it does the same thing on stock clocks.

And I can use release 44 with no issues but I WANT THE BOOST!

But, I will look further into it, and I may flash the BIOS, but I never had to with my 750Ti, so I don't want to unless I need to.

try to run with -i 22 or less. Less power consumption with lower intensity. Is your PSU good enough?

Try to decrease clocks significantly below standard. If the problem remains then this is not a clock/power consumption problem.

P.S. Did you try benchmark mode? Is situation the same?

It maybe you card/driver problem. If power consumption goes over 100% TDP then card goes to some low power mode. And again, and again, and again.
Try to decrease clocks or maybe you will need to flash bios with higher TDP.
I did it on my gtx750 cause by default its TDP was only 38W and it went "resting" on every serious load.

exactly ...

unless there is some serious flaws in the programming ( which doesnt look like there is at all ) then it just may be the clocks ...

on our farm - there is NO overclock - all stock - on all machines ...

this way - if there is such an anomaly like what you are experiencing - it will be much easier to diagnose ...

these nvidia cards are all built in with 'safety' cutouts so as explained - unless you are willing to flash the firmware of the cards and play with the settings - then mine with ONLY stock settings with NO oc or intensity parameters and see how it goes ...

if all is well - start to play with the settings and see what the optimal settings are for your card ...

if all is not well - and you have checked ALL the system settings and components - then it may be a reason to check the card ...

always start stock - and go from there ...
