definitely worth investigating further ... as the whole farm is based on the x11 algo mining ...
will let you know ... and tanx again ...
#crysx

That is 20% more hash.

If your profit today is 20% after the electric bills are payed, the profit will  increase 100% with overclocking.

A few percent is what makes the difference between a broke farmer and a rich farmer.

agreed ...

im almost finished my work here - so sleep and rest in a few minutes for me ...

will definitely look at what can be done tomorrow and the rest of the week ...

tanx again sp ...

The windows builds produce more hash, and use less power. You can get 100% more  profit if you switch to windows.

Just had a look, and a windows 8.1 license is 119€ for me. The pro version is needed for remote desktop (if you don't want to move display, keyboard and mouse around) and costs 279€.
Even if the hashrate is better, it's going to take quite some time to ROI that license cost. With that kind of money, I'd rather buy two more cards and buy you a few beers :-/
Maybe it's OK for people who have 6*970 rigs. But for me and my measly 3*750ti rig, it's a no-go.

Edit: Windows 7 pro 64 bits is 'only' 180€ in OEM version and should upgrade for free to windows 10 when it is released...

this is one of the reasons why i left windows altogether many many years ago ( i was a windows 'professional' onsite and network infrastructure consultant ) ... apart from the instability and 'graphics only' control - which is still current to this day ...

linux just blows it away when it comes to all of those points ...

but i can assure you - even with a farm - no matter what rigs you have - the cost is bloody ridiculous ...

a 'free' upgrade to windows 10 - with HUGE restrictions ... ie - you MUST have a running and licensed copy of windows 7 or 8 and above to be eligible for this 'free' upgrade ...

again ... we are sticking to linux and im personally not running anything else except for the ONE windows machine - just because i 'need' to ...

all the rest are linux - including my desktop ...

anyway - im just hoping there will be more advances in the opensource arena and linux in the very near future - to allow all these awesome apps and utilities to become much more proficient in functionality and performance ... and hopefully this will make closed source a dying area ...

Should I try using the nvidia-smi tool if I'm OCing my 750Ti with GPUTweak? Been on westhash now for 32hrs. and getting 6325+ kh /w quark.

wouldnt think you would need to use anything but that for windows would you? ...

Nope...just wondered if nvidia-smi had any advantages if I'm getting that with Tweak. Thank you

[sambiohazard]

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.

x11            3075 KH/s
x13            2420 KH/s
quark         6050 KH/s
qubit          4825 KH/s
skein         79 MH/s
neoscrypt  170 KH/s
lyra2          710 KH/s
nist5          9400 KH/s

Thanks
My numbers are low because as i mentioned i had 50-60% load on CPU which reduces the hash on most algos, so these are conservative numbers. It gives you a margin when using auto-switching. Also, you are right about skein, first i got low numbers then it peaked at 89 & 276. Above are avg hashrates.

[sambiohazard]

@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!


http://mojoimage.com/free-image-hosting-13/776q.jpg

@sp_ please if you can change that and not hash when there is no connection then it would be good power saving & thus more profit. Most of us are away from our PCs & it wastes power if there is no connection (which has become norm with multipools nowadays). Is it possible?

[rednoW]

Try "start /realtime ccminer.exe --cpu-priority 5"

[sambiohazard]

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.

Sample config: ccminer.exe -d gtx750ti -q -s 1 -a ALGO -o POOLURL:PORT -O USER:PASS [scrypt/cryptonight switches]

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.

I guess most of the hashrate difference is due to CPU load. It reduces my hashrate. I get 5700, 5500,5300 on quark with 0,25,50% load on cpu. Its similar for other algos. I was running this test with 50-60% load on CPU. Also these are avg hashrates instead of peak numbers. I download from your releases on github so you know better than me about version of miner lol. Your cryptonight numbers are impressive but i dont mine it regularly so its ok. If you have some optimized Magi CPU miner, i will be interested in that.

[sambiohazard]

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 ...

I think they are still focusing on gamers & designers, who are mostly on Windows & Mac. That might explain lack of support for Linux. Also most businesses are on windows.

Where do I put that? In .bat file? Also i mine BCN or XMG on CPU, will this effect that in terms of hashrate?

i know ... i used to be part of the team for ( and also the team lead for some ) companies like fairchild and american express ...

its a pity that back then they didnt use linux so much .. but now its more prevalent as linux itself has matured quite a bit - so cant blame them ...

but your are correct - that nvidia and amd are focussing more on gamers and designers - and only really concentrating on hpc clusters with their really high end cards - like tesla ...

I haven't observed this problem. I haven't specifically tested it but I have noticed the GPU cooling fan roll back
when the stratum connection drops.

This could be used as a form of backup, running two instances of ccminer on the same card but mining different
pools. If one disconnects the other picks up the slack. This would work as long as the combined hash rates of
the 2 instances add up to the hash rate of a single instance.

I've also wondered about running two instances but on different algos. I'm curious whether the different algos
would better utilize all the resources available or whether the constant context switching would kill cache
performance. The choice of algos could make a difference. I might give this a try but not for a while.

look's like Yaamp is down. I expect more pools to die. The problems with pools are that they get too greedy. Currupt pools are the worst.

Well, it now seems official, yaamp is dead.

https://twitter.com/yaamp1

I only have a small balance pending so I'm not too concerned about it.

Trademybit's web site is still alive and they did leave a teaser in their shutdown message. I thought
they might have acted on it with quark's performance in the past several weeks.  Maybe yaamp's
demise will provide some more incentive to them. Just wishful thinking.

My problem with solomining is I'm not a speculator. I'm not interested in trying to find promising
new altcoins, avoiding the scams,  to mine for a short in and out. I never did this in the stock market
either. There aren't many coins that are practically mineable and are worth keeping, meaning they
have a substantial market cap and trade volume, and aren't likely to fade into oblivion. Only DASH
comes to mind. Then there is the hasssle of maintaining multiple wallets. I'm too lazy for that.

I could go for another service like nicehash where miners and buyers are brokered. Most rental
services rent out their own mining equipment and/or only mine sha256 or scrypt. You just have
to look at the x11 volume on nicehash and how fast quark ramped up to see it would be popular.
It would also address the complaint about auto-exchange pools, that they kill coins with their insta-dumps.
With fewer pools to mine most of the rentals would be solomining, as I suspect they already are.

Multipools are just like mutual funds, a natural part of an open market. If crypto
