That Asic Advanced thing looks to me like an April Fools' Day prank...not necessary a scam.

RainmanCC is a scammer!

Go to https://github.com/cdmackie/rpcminer-mod

and either use git and checkout the repository, or just click the "Zip" button at the top to download it.

To run, you only need the files from the "bin" directory, so extract the whole thing or just that.

Open a command prompt, go into that bin directory, and run the command line:

rpcminer-mod-cuda.exe -url=http://: -user= -password= -gpu -aggression=8

where and are your pool server, e.g. api.bitcoin.cz:8332, and obviously and

If you get an error whilst it's running, it may be because the GPU processing is taking too long and by default Windows thinks the GPU has crashed after 5 seconds.

So try:
1) reducing aggression
2) add "-gpugrid=256" or "-gpugrid=512" (see which works and is best)
3) unplug the monitor from the card (if appropriate)
4) adjust the Windows GPU timeout settings (http://msdn.microsoft.com/en-us/library/windows/hardware/ff569918(v=vs.85).aspx), e.g. TdrDelay to 20 and TdrDdiDelay to 60.

Once its working, you can increase aggression and/or gpugrid to get best settings.

hi guys im watching this thread last day can you tell me how to download this? im interested to try it to my gtx660ti im current hashing 101.5mh/s via cgminer v.2,11,4

Okay! I actually got it to work properly.  I created a batch file in the same folder and this time actually included the words rpcminer-mod-cuda.exe at the beginning haha  I know this is pretty typical stuff for you guys but this is one of the first times I've had to deal with batch files.

Initially it crashed, then I added the command -gpugrid 512 and it worked properly. 
all the arguments I'm using are -gpu=0 -gputhreads=256 -aggression=8 -gpugrid=512

Normally, with a basic 50miner program my nvidia GTX 670 will max out at 92-93 mH/s, but now it seems to be pushing 96+ mh/s.  I'm going to continue to tinker and see if I can push it higher. 

I really appreciate you guys being so patient with me.  But where exactly do I even input these commands?  I do know how to make a batch file, I go to notepad, type the commands I want and save it as a .bat, drag the file in the folder and try to run it, but this doesn't seem to work. 

800 core, instead of 700. Pretty modest OC. Could probably go higher, but this is my main machine & don't want to risk blowing it up...

Yea im doing ctrl-c to exit out of the app in a dos prompt on win 7

How does your 480 beat a 680? you overclocking at all?

Im getting around 122~ give or take with cgminer

I think the general crashing is just because the code is throwing an exception when it sees an error. I'll change it to exit nicely.



What exactly are you seeing here? I've only got an Amazon EC2 instance to test on, and I don't get an issue. You're Ctrl-C-ing?

You don't need to extract 7z files unless you are compiling it yourself in Visual Studio.

Otherwise you just run it from the bin folder:

e.g.

rpcminer-mod-cuda.exe -url=http://: -user= -password= -gpu=0 -gputhreads=256 -aggression=8

where
is your pool address, e.g. 127.0.0.1 if mining solo or something like api.bitcoin.cz
is your pool's port, normally 8332
is your pool login
.. you guessed it

If you get an error whilst it's running, it may because the GPU processing is taking too long and by default Windows thinks the GPU has crashed after 5 seconds. So try reducing aggression, or add "-gpugrid=256" or "-gpugrid=512".

If you are still getting problems, can you include the error text you get.

Tomorrow I write you a simple Bach file To Start the Programm.

I've got a GTX 670 and 50miner (via poclbm or cgminer) gives me about 92 mH/s. I'm wanting to see what this does

I'm going to ask a real noob question here, but where do I extract the 7zip files to?  Clicking on the .exe from the bin just causes it immediately open and then stop working, and I can't input any parameters. 

Can you run the miner same minits that we can see the hashrate. My driver under windows also crash, thats windows like shutdown^^

guiminer poclbm gives me ~137.5

Can you run the miner same minits that we can see the hashrate. My driver under windows also crash, thats windows like shutdown^^


Plese use -aggression=6 as parameter, the gpu is to slow and braek the kernel run limit.

What hashrate where you getting without cuda?

I'm running it now, works as is.

I just made the appropriate changes and started a new run. Will let you know in a few how it works out.

FWIW, I've been running ~140-145'ish on cgminer, overclocked to 800 core (700 stock). This is my general use machine, so I didn't have aggression set to keep desktop usable, but will run at 7 for testing for you. I just checked my average hashrate on cgwatcher, and it is 140.1.
