What miner are you using for the XMR? And hashrate?

Thanks

edit; To the conversation about Windows vs. Linux, I've never been a linux person but wish I had at least learned more about it. I've been using Windows a looong time and do like it but the biggest drawback for me....the dreaded UPDATE /w restart.

You might want to check out the EVGA Power Booster for the PCIe bus. (assuming you have a spare PCIe slot -- x1 is all it needs) Especially for non-PCIe connector cards, it can help with +12V via the bus.

I swear it helped my rig be more stable, as I am using 2 relatively weak PSU's to run a rig with a non-PCIe connector 750Ti and a GTX 970, plus mining XMR with the i7 CPU.

I couldn't run V45 or up until I installed it, as the +12V power seemed to sag over and over and my hashrate suffered, so I was stuck with V44. Now, with the Booster all versions run fine.

RELEASE v50--

With SP_ release 1.5.50, my 6x750ti FTW rig is getting 6.35-6.5Mh/s per card and 38.6Mh/s for the rig mining Quark.  This is at a 96%+ accept rate and nearing 15,000 accepts.  There is no real speed increase here from earlier releases.

The 2x970 FTW+ rig gets about 15Mh/s+ per card, and 30.2Mh/s for the rig minng Quark.  This is at a 98%+ accept rate and nearing 20,000 accepts.  This is an increase of about 400kh/s for the rig from earlier versions' best.

The 750ti SSC (non-PCIe connector) cards mine Lyra2/vertcoin at 725kh/s or about 4.1Mh/s for the rig.  This is a speed improvement of about 7-10kh/s per card from earlier versions.  I think I need a bigger power supply on this rig, it won't mine other algos without crashing.  This rig has always been less stable.

ASUS GTX750Ti 2GB DFseries OCed with 6pin getting same 6500 hashrate.

this is true ...

but the situation is quite a bit different with the farm ...

there is no way - and i mean NO WAY - of maintaining a farm of miners that are purely windows based with the ease and granular control that you have with linux ...

and the farm is not getting any easier the larger it gets ... every month we try and add at least another system ...

i was originally running seti@home also ... was #1 credit in australia at the time as i had run EVERY machine ( with permission of course ) on the networks that i would administer ... was awesome ... 98% of the machines on windows and they admittedly did run stable ... until you had to work on them ... which was what 98% of the machines were - desktops ... then you had issues ...

if it was one or two computers - i wouldnt have an issue ... but not a farm ...

stability - reliability ... not much can beat a linux system in that arena ... AIX maybe ( it is unix afterall - or tru64 ( dec alpha ) ) - but even then IBM have a huge linux division now which should tell you something ...

anyway - this farm cannot run that easily on windows - only due to the massive limitation we have for maintenance - namely me ...

#crysx

It depends on what the machine is running.
I had linux servers with uptime of over 3 years (running cpu and hd processes all the time).
There are countless reasons to favor linux (remote admin, system updates...) and you can find many for windows as well.

But all of this doesn't matter: if you are good on windows, or if your application runs on windows only, you'd better use it ;-)

Windows has its drawbacks, but I can also say that I ran a Windows XP machine in 2001-2002 that was overclocked 50% (1GHz Athlon @ 1.5GHz), cooled by air, and had an uptime of more than 6 months. And that was running Folding @ Home when otherwise idle.

Windows machines can be just as stable as any other OS, if configured correctly.

they are quite impressive figures sp ...

but with the suggestion that windows would be the way to go with farm - i cant agree with you ...

the amount of work AND maintenance on windows is beyond a joke ... i was a windows professional a few years back - and the reason i made my money was because windows fell over ALL the time ...

yes they have made some improvement to the operating system - BUT reliability is the one thing that this farm cannot do without ... and it has that because it runs under linux ...

even the one windows machine that i HAVE to have - bluescreens and requires reboots and so happily gives me headaches more often than not - and its just a desktop ... let alone run it for months on end as a miner - like the linux systems do ... and i really do mean MONTHS without a reboot ... just mine and dont stop ...

so the sacrifice for this farm by the looks of it is pure and simple - reliability ( and SO much less headaches ) but less hashrate as opposed to higher hashrate but the instability of windows ...

ill take linux any day and lose a little hashrate until someone codes a way of overclocking with linux ... meanwhile i barely touch the farm unless im doing a major overhaul ( like the current rebuild we are taking on ) ...

it might be a good idea to build a windows system for mining and test how it runs with 6 cards ... i really would like to see the overclocking ability of these cards ...

in a few weeks maybe ...

in the meantime - ill keep them 'stock' and just run them the way they are ...

which is why those parameters in ccminer would be invaluable ...

SP-mod release 50 Mining quark

The non powered

http://www.gainward.com/main/vgapro.php?id=926&

Draws 40-45 watt. and does 5750Khash on standard clocks.

the powered (6 pin)

http://www.gigabyte.com/products/product-page.aspx?pid=4948#ov

draws 60 watt and does 5550Khash on standard clocks.

But if you reflash the bios to the black edition, the hashrate is 6100 and with overclocking I can reach 6500. (The gainward is not able to reach these speeds because it needs more power)


so 1 MHASH more with 15-20 watt more consumption.. But if you don't overclock you loose the 1MHASH

Perhaps it's time to switch your farm to windows. If you manage to lower the powerrate from 60w to 40watt, your profit will skyrocket.


I have messured some of my non powered 750ti cards on standard clocks, and they draw around 40 watt in the wall while mining.
Other users seems to report up to 66W in the wall.

i think you are spot on with that ...

msi afterburner does one hell of a job too ...

who ever can create an oc app - commandline as well as gui - for linux will make it so much easier ...

we would have no issue donating for that to happen ...

these are the two cards we have in the farm ( apart from the 16 x gigabyte 280x cards ) ...

http://www.gigabyte.com.au/products/product-page.aspx?pid=4948#ov ( GV-N75TOC-2GI )

http://www.gigabyte.com.au/products/product-page.aspx?pid=5160#ov ( GV-N75TOC-2GL )

the first one is the powered one ( with the 6pin power connector - GV-N75TOC-2GI ) and the second ( non-powered with no extra power connectors - GV-N75TOC-2GL ) gets all its power from the pcie bus ...

their hashrate are almost exactly the same ...

the basic difference ( from what i understand ) is that the non-powered one ( GV-N75TOC-2GL ) cant oc as much as the powered one can ( GV-N75TOC-2GI ) ...

i unfortunately cant test this currently as i cant overclock via linux - hence the dilemma we have for the farm ...

#crysx

I think this problem exists under linux only. On windows you have such third party tools as nvidia inspector that can change a lot in command line.

im not sure either mate ...

but one thing i am sure of - is the amd cards work at max capacity due to the linux drivers and optimizations that devs like wolf have done ...

commandline overclocks are easy with sgminer and amd - its just a matter of finding the maximum they will oc - and that is just a matter of changing values ...

obviously when talking about nvidia - its very different ( with card make and drivers ) but the deal breaker with nvidia is simply that one cant just change a few commandline parameters to 'play' with oc ... even though the options for such tweaking IS there ...

further - you are right in that the cards themselves ( via the bios ) may have limitations that wont allow 'too much' overclocking ...

thats when sp's suggestion of flashing the bios / firmware would probably help ... but i prefer not to fiddle with the cards on that level - unless there is a massive improvement in hashrate and power draw ...

for the moment - i would rather just have the availability of commandline parameters to do the tweaking to as far as the cards can go ... like the amd's ...

#crysx

But flashing 60%TDP bios will not raise real power consumption. You just make safety wall to be higher ...

Most users don't overclock. My point is if you don't overclock you don't need a TDP of 60WATT. the default 38.5 is more than enough to keep the hashrate. Some cards come with a 6pin power adapter and flashed to use 60W TDP. these cards are not producing more hash than the cards that comes with a default 38.5 if they are not overclocked.

Without bios TDP mode you won't gain from overclocking due to some kind of throttling on heavy algos (scrypt, quark). Maybe under linux this behavior is not implemented in drivers ... i don't know ...

Also you need an option to set fan speed higher then default when overclocking. Default fan control rule makes card to go over 50C degrees under load (in my case). This is not good.

the issue with all this sp is that most of the apps that are designed for overclocking are all windows based ...

the only one that tried to do something about that a while ago for linux - is no defunct ... no updates for years ...

there are lots of pointers and tutorials - but never anything solid for linux users to 'easily' oc - especially via commandline ...

what you are proposing is the simplest way of doing it - via command line - windows or linux ... on 'stock' bios ...

you will hit a max wall - and thats as far as it will go - no bios modding or anything ...

#crysx

I think you are not right. When you change TDP in bios you just prevent card of being throttled. The actual wattage doesn't depend on bios set TDP but only on algo.
My GTX750 went in economy mode without any overclocking on heavy algos when it was with default TDP in bios. In economy mode performance is degrading.
So changing TDP in bios helps you to prevent throttling and leaves space for further overclock. The dark side is possible card burn if it is n't designed to work with such wattage for long time ...

The Non powered ti's actually has a TDP of just 38.5 Watt in the bios. But this can be changed to 60 watt. The increase in watt doesn't increase the hashrate though. Without overclocking, you only waste more power...
