5.6MHASH@38W. Low clockspeed/memory speed

Seems that gtx750 with high oc is more energy efficient then 750ti in low clocks )))

quark 6mhs with such run ... but neoscrypt with 190khs is more profitable now

[fenomenhaa]

C:\Program Files\NVIDIA Corporation\NVSMI>nvidia-smi.exe  it's not working on me? what i need ?

[tbearhere]

Same thing over and over.  It says.

'cuda_check_cpu_setTarget '  at line 28 : unknown error

This happens on any version.

you need to upgrade to the latest driver.

Did you mod the bios to get 65W power CAP? my cards are @ 38W and 45W. (early 750ti cards without the 6pin power connector) Do you have a 6pin powerconnector to your card?

I did all  ... no good.
I have 16 gig ram.
It has been doing this for some time..but right now I can't get it to last 5 minutes.

5.6MHASH@38W. Low clockspeed/memory speed

that is more our rates ...

we have stopped mining quark for the time being - due to the personal / work environment we are in at the moment ...

for the moment though - our favourite algo - x11 - is on the farm again and is hashing at a comfortable rate ...

the latest commit dropped the hash by about 20KH from the previous compile - so we have reassigned the previous compile until further testing can be done ...

5 x gigabyte 750ti oc lp ( nvidia test system - fedora 20 x64 - cuda 6.5 ) = ~14000KH with the latest compile ... and ~14022KH with the previous compile on x11 ...

keep up the awesome work sp ...

we now have a total of 4 servers - yours being one of them - for the donation links fully active ...

a few issues still - but that seems to be from the amount of algos we have running on the one server - so will probably end up dropping a few of the less used algos from the server ...

as for the farm - we are sticking to x11 for the time being - while the upgrades to the electricity and miners and software are completed in the next week ...

quark hashrate is about double that of x11, so it's still the most profitable for me, except when neoscrypt goes over 7 BTC/Gh/day.
this miner is extremely good mining neoscrypt, it uses less power than quark (it's the opposite on amd, afaik).

Remove one of the cards. Mine for a while. If it works, change the risercable to a powered riser, and mount the card again. Check the powersupply and remove  dust.

quark is very 'profitable' in terms of mining compared to most other algos - but we funnel our farm ( in three sections ) through mintsy and rent the hash out while we mine other coins and trade those ...

this is the 'test' we are undertaking currently to see what is the most profitable ( by means of btc ) way of mining ...

we were mining with nicehash exclusively for a little over two weeks - now we will go about this way for the next two weeks ...

the preliminary results will show which 'seems' to be the better way of mining with this simple short testing phase for us ...

there are too many things going on at the same time - so the farm needs to just be running at the best rate as it can - and x11 with rental options seems to be proving more than straight mining ...

BUT - that is not conclusive nor accurate for the two days that it has been ... apart from that - the electrical systems we have in place have been 'shaky' to be put bluntly ...

the issue with this setup though - is that we cannot direct the hashrate TO nicehash FROM mintsy due to teh incompatible extranonce issues between the two sites and their stratums ...

will keep you posted if you like ...

They are on power risers... it's ccminer that is the problem I think..because on crash it won't restart either.

      some progress on neoscrypt:  ~850kH/s on gtx980
                                                ~500kh/s on gtx780ti
                                                  201kh/s on gtx750

Hope Djm34 will share his improvements.

no restart after crash usually points to the windows drivers crashing ...

have you reset the machine? ...

if not - do so ... it will more than likely still crash - but if it mines even for a little bit after the reboot - then it will most certainly be your drivers that you have installed ...

downgrade - or upgrade the drivers ... that may fix the issue ...

if it continues with the SAME crash - then downgrade the ccminer version you are using ( or recompile a previous ) ...

let us know what the results are ...

He has also done 0.5MH/s improvement on quark on the 750ti and 1MHS/s on the 980

Please donate some and he might share it with us?

did some optimization on quark: +75% (roughly)  
yeah... well  

10 Mh/s on 750Ti?? That's really great!!
will you merge the mods, make a new repo or sell it?

well... that was a bug it is rather +1MH/s for 980/780 and 0.5MH/s for the 750ti

[rednoW]

Did you mod the bios to get 65W power CAP? my cards are @ 38W and 45W. (early 750ti cards without the 6pin power connector) Do you have a 6pin powerconnector to your card?

Yes, bios is modded to 65w cause default bios went throttle on high load even with stock clocks.
It's a cheap palit card without any power connector.
I used it in std pci-e x16 port before, now it is on pci-e x1 with rizer cable (with additional power rizer)

p.s. In fact i was lucky enough to get this one, it has only 1.125v voltage and ASIC quality rating (in gpu-z) more then 80%. I tried to find some other 750 or 750ti but all of them was with higher stock voltage and less ASIC quality - so i refused.

Well it seems the humidity at 92% was causing it. And ccminer doesn't have anything build in it to start mining again at crash.
thx
