#crysx

I will continue to support linux. But the memclock/gpuclock is windows only for now.

we appreciate it sp ... especially all the work you have done so far ...

but i have to admit that such an advancement like this in ccminer would be a much missed feature for linux ...

what is it specifically that is the issue with this ( for it to be 'just' windows currently )? ...

is it the drivers that nvidia bring out? ... or the way that ccminer is built? ... or a combination of both? ... or something else entirely? ...

Find an updated version of the nvidia-smi tool. Does it work to change the clocks with this tool for your graphic cards?

If not, I cannot help you on linux. It's a API/Driver problem.

on windows the tool is located here:

C:\Program Files\NVIDIA Corporation\NVSMI

reason why I'm not buying nvidia: amd drivers for linux are bad but the situation with nvidia is even worse.
another reason is I wanna see the r9 3XX in action before buying for the winter.

Take it as a rumor for now but the only cards probably worth it will be the top of the line 3xx.

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 ...

but its all conjecture for the moment ... would be nice for a redesign though ...

R9 300 series will not be a rebrand only: there is new memory technology and other goodies; but they'll probably, at least intially, still be based on 28nm tehnology.

First set the right mode

nvidia-smi -pm 1

then set the right clock.

here is the tool's helpfile:

  -pm,  --persistence-mode=   Set persistence mode: 0/DISABLED, 1/ENABLED
    -e,   --ecc-config=         Toggle ECC support: 0/DISABLED, 1/ENABLED
    -p,   --reset-ecc-errors=   Reset ECC error counts: 0/VOLATILE, 1/AGGREGATE
    -c,   --compute-mode=       Set MODE for compute applications:
                                0/DEFAULT, 1/EXCLUSIVE_THREAD,
                                2/PROHIBITED, 3/EXCLUSIVE_PROCESS
          --gom=                Set GPU Operation Mode:
                                    0/ALL_ON, 1/COMPUTE, 2/LOW_DP
    -r    --gpu-reset           Trigger reset of the GPU.
                                Can be used to reset the GPU HW state in situations
                                that would otherwise require a machine reboot.
                                Typically useful if a double bit ECC error has
                                occurred.
                                Reset operations are not guarenteed to work in
                                all cases and should be used with caution.
                                --id= switch is mandatory for this switch
    -ac   --applications-clocks= Specifies  clocks as a
                                    pair (e.g. 2000,800) that defines GPU's
                                    speed in MHz while running applications on a GPU.
    -rac  --reset-applications-clocks
                                Resets the applications clocks to the default values.
    -acp  --applications-clocks-permission=
                                Toggles permission requirements for -ac and -rac commands:
                                0/UNRESTRICTED, 1/RESTRICTED
    -pl   --power-limit=        Specifies maximum power management limit in watts.
    -am   --accounting-mode=    Enable or disable Accounting Mode: 0/DISABLED, 1/ENABLED
    -caa  --clear-accounted-apps
                                Clears all the accounted PIDs in the buffer.
          --auto-boost-default= Set the default auto boost policy to 0/DISABLED
                                or 1/ENABLED, enforcing the change only after the
                                last boost client has exited.
          --auto-boost-permission=
                                Allow non-admin/root control over auto boost mode:
                                0/UNRESTRICTED, 1/RESTRICTED

[sp_]

Adjusting the clock settings could give a boost of 20% without drawing more power on some cards in some algos.

I will continue to support linux. But the memclock/gpuclock is windows only for now.

The results i posted are from Linux, the hash rates seem pretty comparable to Windows
results, no idea about the TDP.

exactly my point ...

we dont have 30 machines .. yet ...

but even with the farm in its present form - it would gain a huge boost ...

the only factor is that using the smi tool is fiddly and VERY complicated ...

hence the reason for the wait for the simple --gpuclock --memclock type of parameters ... which are a GodSend for ccminer ... ( and make it VERY simple in sgminer ) ...

ive used and tested the smi tool - it does work ... BUT the amount of work put into it is monstrous ...

nvidia do not make it easy - and easy is what we want ...

in any case ... there is much more work to be done on the current farm while we build the 'new' one ... so simplicity is the hey to ANY miner for ANY system - whether windows or linux - whether single machine or farm ...

next week im personally committing an entire week to the farm then full time into this ...

will let you know how we go with it all sp ...

tanx ...

Can you run the nvidia command line tool to check wich clockrates the card is running on?

I get 3420KHASH on my overclocked 750ti in windows when mining x11.

[sp_]

Make a textfile with a script and call it sp.x:

nvidia-smi -pm 1
nvidia-smi -ac 1350,1350
ccminer -quark ...... pool btc adress etc.

(you might need to change the paths and give the correct admin rights to nvidia-smi)

chmod +arwx sp.x


then just write sp.x and press enter.


Then you need to find the correct clocks for your card. Replace the 1350 / 1350 with something bether. You should also messure the powerusage to get the optimal hash/watt rate.

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? ...

#crysx

Crysx, I don't see the problems you are having with westhash. I've had a continuous connection to the quark
pool for 1575 minutes. As I mentioned to Masked_Immortal the only problem i see on westhash is the
one retry message on startup. Does your proxy support extranonce?

Ditto on the search for a good multipool. I have used simplemulti and xpool but the're focussed on x11/DASH, and neither
has a quark pool.  I don't know what's behind Mintsy's front page. Globalhash looked promissing but came
and went in less than a weekl. It's looking like it's nicehash & westhash for now.

tanx sp ...

im familiar with writing very BASIC scripts ( as the entire farm runs on scripts ive written for its automation ) ... but the setup is the major issue with this ...

the settings are never persistent which is why im guessing you are adding the settings into the initial part of the script ...

will have a look into this much deeper with the test machine tomorrow as its late here now ...

its interesting that the overclocking brings in such a difference ...

under x11 - the most i can squeeze out on stock clocks with the gigabyte 750ti oc lp card is about 2850KH ...

whereas you are getting more than 3400KH ...

definitely worth investigating further ... as the whole farm is based on the x11 algo mining ...

will let you know ... and tanx again ...

yes - the extranonce 'feature' is built in with it ...

stratehm proxy ... though it is one of the earlier ( and in my opinion more stable ) versions ...

will test how the newer version responds ... ive contacted westhash support - so will see what they say about it also ...

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.

Best part is, I hear Nvidia won't get to use the new memory tech for the better part of a year. The first ones will probably be 28nm, but if they do get a die shrink too, it'll slaughter the 980Ti, I bet.

good. More cores, cheaper price. What do you need the memory for?
Scrypt mining?

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...

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.
