I set the scrypt algorithm to "sha256d" but this is what happens:

At 1.4 million hashes per second it will take you on average about 51 minutes to find a share.

Yes that's right, you ARE doing it right, but you are also seriously wasting your time.

Okay, how about using an amd r9 270x with cgminer, would that give me around 500kh/s or something?

CPU and GPU mining days for bitcoin mining are long gone. With a CPU you use 1000 times more in electricity than you earn in bitcoin, with a GPU 100 times more than you earn. Each difficulty 1 share takes over 4 billion hashes to find on average, and your CPU is doing 1.4 million hashes per second. That GPU will do something like 700 million hashes per second which is still ridiculously low for the amount of electricity it uses. It is only worthwhile bitcoin mining with hardware that is designed purely with bitcoin mining in mind (i.e. ASICs) today. The days of off-the-shelf commodity hardware being able to meaningfully bitcoin mine ended a year ago.

You are probably getting confused by threads discussing altcoin mining with GPUs. That has nothing to do with bitcoin mining.

Yes as I said in my original post, I was planning on mining mazacoin.
I made a thread here because I had mining difficulties using the sha256 algorithm, which is the same algorithm bitcoin uses.

Thanks for your help

You're spending WAY more on electricity than that graphics card will ever earn you. You'd be better off with a USB miner (~$20 on ebay) but even that will never pay for itself either.

Hi, I posted in the altcoin mining sections but didn't get any responses yet, that might be because the algorithm is based on bitcoin here.

So recently I have been mining scryptcoins, and now I wanted to mine mazacoin, based on the SHA256 algorithm.

However, when using cudaminer, I keep getting the notice "boooo" and my share is not accepted.

.bat file:

Code:

cudaminer.exe -o stratum+tcp://mzc.mineoncloud.com:3339 -O Username.worker1:pass

Why doesn't it mine? I couldn't find anything on the net.
