yeah power meters are pretty cool. i have a cheap-o Kill-A-Watt and the display updates only once a second, but the range of fluctuation is only a couple watts.

i'm drawing 2.75A from the wall.  All my miners run on the 80+ gold-rated supplies. Looking it up, put in a 12% gain in efficiency and the system is drawing 290W total at the PS.  System is:

• Intel Celeron G1830
• Biostar H81S2
• 5x PCI-e 16x-1x ribbon risers
• 5x Giga 750ti OC
• 1x Kingston HyperX 8GB DDR3
• 1x cheapo Sandisk Glide 16GB USB stick running kopiemtu

here's the Seasonic I use: http://www.hardocp.com/article/2013/10/30/seasonic_gseries_g750_power_supply_review/4#.VVln4a3ImkA
This one's efficiency is pretty flat all the way up to full load.

The +125 MHz overclock in Linux gives me 6.0 MH/s right on the nose, for the Giga 750ti OC cards.

Hi guys here are my results for various algo. I used simple config w/o any switches for all algos except scrypt ones & cryptonight algo. I used ccminer release49, cudaminer 2014-02-28, & ccminer-tsiv-20140926.

I was also running cryptonight on 2 CPU cores & atleast 10 POS coins were staking . So take these results with a grain of salt. My machine is i5 4670, 8GB RAM, Win7 64-bit, MSI GTX970 & GTX750ti. I measured power consumption using APC Powerchute s/w for the cards only not whole machine. I basically noted the difference in power consumption while machine was idle & while mining. There was very little fluctuation so figures are pretty accurate.

Yes i like it. Nice work.

The power numbers for the 970 are almost all over spec (145W), but the 750ti numbers are almost all a little
under spec (60).  That puts the 970 power draw the same as the 980 (165W), or maybe the 980 also draws
more than spec. I haven't got any power data to compare.

Your hashrates, except skein,  on the 750ti are lower than mine. I may not have let skein run long enough,
it was a quick test and I wasn't too concerned about that algo.

My card is an EVGA GTX750ti SC, 1255 Mhz boost clock. I think the MSI is around 100 KHz lower.

My observed hashrates from yaamp (when it was alive) with ccminer 1.5.50-SP default parms.

Did you let it retry a few times? When I start quark on westhash it always
fails to connect on the first try.  To be more precise, It always displays that
message, but no other error message when starting up.

@joblo
yes i left it to try several times, no success
also i am not a coder and i am not familiar with the structure of miners codes like ccminer and sgminer
 in sgminer when the server is down there is no gpu load
but it seems that in ccminer my gpu is under full load even when there is no connection to server!

Sambiohazard your numbers are low, did you compile a 64 bit version? Use x86 and windows for the fastest speeds. my results are closer to the numbers by joblo.
What cards are you using?

My private cryptonight donation miner does 450 on default clocks and closer to 500 with overclock on the 970. The 750ti goes up go to 310 with max overclock.

[sp_]

I have implemented --gpu-memclock and --gpu-engine parameters in ccminer now.
Will messure the watt and get back to you.

Looks like the --gpu-memclockand --gpu-engine will only work on windows for now.

With exact clock settings it will easier to compare the different cards and their performance. As you can see in the tests performed by the users, quark is 17% faster on the evga than the msi (model?)  card on standard clocks

yes yaamp is down, i tried only quark @ nice/west and it didn't connect.

quark ALWAYS seems to be down at westhash ...

well - not always - but a lot of the time ... ...

ive emailed support regarding the continuous disconnects of ALL algos for the donation links ( stratum proxies ) and have yet to hear back from them concerning that ...

it seems that if the ip that connects to their stratum servers stays idle for a while - it kicks it off and doesnt allow a reconnect ... which is why ( if you are using the donation links for sp or granitecoin at the moment ) are not functional ...

They used to failover to yaamp - but alas - yaamp is down indefinitely now ...

does anyone here know of a 'good' multipool that does the same thing as yaamp and westhash / nicehash - that we can setup as a failover for the donation links? ...

i wont be switching ( about to be ) 30 + machines to windows sp ...

it becomes way too much maintenance for each system - and way too expensive for the licensing to microsoft ...

id rather spend all the money upgrading the farm AND donating to devs that will support the effort ...

you have a fantastic ccminer fork here - one that stands out from many that are out there ...

not supporting linux in this way dulls the shine you have with this fork ...

and the community support that you have with those that mine with linux - will be disappointing to see that you wont support this side of the community ...

our farm was completely amd ... now its a hybrid amd / nvidia - though mostly nvidia now ...

the headaches involved with catalyst drivers and the lack of linux support was beyond us - so was one of the major reasons we changed over to nvidia - apart from the power consumption / hash savings ...

either way - it was worth the effort ... it still is ...

but to change to cumbersome top heavy os like windows JUST to mine? ... not a chance ...

will find another way and support that way ...

until microsoft decide to release a FREE version of windows ( which looks like version 10 anyway ) - even then we will be hard pressed to reconfigure and redesign the ENTIRE farm for that os ...

will consider where we go next once we see how the 'scene' goes on this end ...

if amd are going the way they did with 7970 etc which were rebranded ( and that was it for the first round - just a rebrand ) as 280x - then for the next 6 months - we will not really see anything worth the while ...

unless of course they decide that an actual rebrand AND redesign is what they will bring out ...
