[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[cayars]

cyntheman,

Can you by any chance remove the card in the 16x slot and try running either program again with only the 1x slot populated.
Then do the opposite and run with only the 16x slot populated and not the 1x.

Let us know what you get.

Hi,i've just bought Nvidia GTX 750 Ti ,please help me step by step start ccminer on Win 7 X64 (noob level)

Thanks in advance

If you haven't done so yet after installing card in computer go to http://www.nvidia.com/Download/Scan.aspx?lang=en-us and install video drivers for 750ti and then reboot.

What coin do you plan on mining to start with? Have you downloaded the wallet for the coin yet?

Have you ever mined before with any video card?

I've mined before but with 280x and i've seen that with 750 Ti on X11 algo reach 2,1-2,2 Mhrate but i don't know how to configure ccminer or bat file

Super Easy with the 750ti

Inside a batch file put this line:
ccminer50.exe --algo=x11 -o stratum+tcp://poolurl:port -u username.worker -p password

As an example:
ccminer50.exe --algo=x11 -o stratum+tcp://us-east1.darkcoin.miningpoolhub.com:20465 -u johndoe.miner2 -p password

Get this working and come back and we can help you OverClock the card a bit to reach the 2.1-2.2MH rates.  You'll probably be in the 1.8-1.9MH rate without OC.

Thanks a lot it's working 1,9-2,0 MH can u help me with OC setting

[drkman]

Is there a way that ccminer will close itself if something like this happens?
If it crashes like this, only a small rate of shares will still be sent to the pool.



Thanks.

yes. modify cpu-miner.c and add this code before this string https://github.com/cbuchner1/ccminer/blob/master/cpu-miner.c#L932

Code:

	if (thr_hashrates[thr_id] > 1e8){
		applog(LOG_ERR, "abnormal hashes %f, exiting with code 211!", thr_hashrates[thr_id]);
		exit(211);
        }

you can choose custom error

I'm on windows 8.1. How do I modify the cpu-miner.c ?  Also, When it messes up  like that is it actually still mining?

[drkman]

Funny that this was mentioned.  I was planning on opening a nomp based pool in the upcoming weeks, and wanted to ask if I setup a percentage to go to c&c, would nvidia miners utilize the pool.  With so many pools existing already, was hoping this would be a way to get hashes sent my way and to distinguish the new pool from the others.  Planning to use the marketing phrase "feeding the green machine", lol.

Been using nomp software for private pools for awhile, and thought supporting c&c directly would be a good option.  And yes to the troll from a couple of pages ago, I am proud to say I am a c&c fanboy.

Was thinking something like 1.25% pool, 0.25% c&c. What is everyone's thoughts on this?  Worth the time and effort?  I certainly hope so.

Also wanted to add, thank you to be Christians for their tireless efforts, and to cbuchner1 specifically, yes the wife let me keep my rig so far, lol.

If there was a ccminer multipool and an easy way to manage ccminer like CGwatcher that also had failover working.  It would be awesome!  Do those things exist?

[cyntheman]

zotac 750 TI single fan

one is in a 16x slot

other is in a 1x slot using a riser

same problem occurs for

asus 750 (non ti's)

This is also in the same setup above. 1 in a 16x slot the other a 1x with a riser.. do you think that can cause issues?

Hey cyntheman You've contacted me on IRC before with the same issues for my compile, right? (Nickname on Freenode is "KBomba")
Seems like bigjme's compile is doing the same (I started doubting myself ) so there might be something interesting about your system.
Can you give the specs of your cpu, motherboard, operating system, etc, etc, ....?

Hey man! thanks for the help as always.

System specs:

Intel Pentium D CPU 3.20 GHZ
1GB ram
Windows 7 64 bit

im including all screenshots from CPUID

I have installed visual basic 2010 and then also installed visual basic 2012 after reading cryptominingblog.. not sure if that has anything to do with it.

I will get home and try removing one of the cards to see if that helps.

Thanks for all your help gents, I'll be sure to tip to all that have offered suggestions.

I hope cbuchner1 will integrate this patch into the main releases.
If you have this error, youll loose most of your hashing power.

Sure thing.  Go here http://event.msi.com/vga/afterburner/download.htm and download MSI Afterburner.  I'm running the beta version.  There is also another program you will want to try after you get the hang of OCing using MSI Afterburner FIRST.  The other program is NVIDIA Inspector.

Another program to have is TechPowerUp GPU-Z.  Start this program first.  It will show you your current settings as well as your adjusted settings.

No two systems are alike so I can't give you my settings.  However, what you will want to do is "play" with the settings.  Start by adjusting the CORE CLOCK MHZ by dragging the slider to the right in small amounts until you get the MHZ at around 1200-1250 or so according to GPU-Z.  You can save settings but when first playing around I wouldn't save anything until you have a good solid speed.  You'll get the hang of it.

BTW, if you OC to much you'll notice that ccminer goes nuts with high hash rates (off the chart high), will crash or you'll see strange errors.  Just back off a bit.

Hope this helps,
Carlo

how many cards did you say you have in that machine?
2 obvious things to check, go to task manager and see what cpu usage and memory usage you have.

each ccminer instance will use atleast 50MB ram, windows 7 is a hog aswell.
you may find your cpu is overloaded and you dont have enough memory

ooo and one last thing, what gen pci-e does your motherboard have? if your running DDR2 which you are, i would expect there to be an issue with the PCI-E version, probably only 1.1

You're thinking the same thing as me.

Two cards are in this machine (2 x zotac 750 TI single fan)

your hunch was right! It IS pci e v1.1

my CPU usage is around 35-50% hovering and each ccminer instance is taking ~ 5,588 K

my memory is hovering around 52% (just have ccminers running nothing else)

http://i57.tinypic.com/opbeqb.png

any way around this? Do you think its a limitation of memory or more the PCI express slot itself?

to get the nicer rates I guess id have to set this up on a newer machine? (one with PCI express 2.0?)

[bigjme]

I would think it was a pci version issue. I wouldnt use anything less then version 2

[myagui]

Nope. Myself here have 3 750TI's on PCIe v1 slots (x16, x8, x4), and have no trouble reaching the advertised speeds as the rest of the 'greenies' here. The one on the x8 slot is actually using a riser, so I guess that one might actually be operating at x1 (it's a 1x to 16x riser). Looks like a CPU bottleneck to me in his case. 

Edit: My CPU is Core 2 Duo E6750 if it helps. Nothing else running obviously, but importantly, windows defender real-time protection is disabled!

I think Nvidia might have a chance at xpm mining...would love to be able to mine it on the 750 ti's with ccminer. 

[cryptomines]

Hey gang, how much drk is everyone making per day per 750ti? If you are mining it that is. Thanks.

Anyone mining x11 coin?
