Title: CPU mining with the original client is viable?
Post by: theGECK on February 24, 2011, 11:30:22 PM
From what I've heard on here, mining with a CPU just isn't worth anything anymore. However, Steve Gibson on Security Now talks about how he mined a block with 4,000 hashes/second (I'm assuming he means kHash/s since he's using the default client).

Maybe I should give it a try. :)

If you have an Intel CPU, use the SSE2 CPU Miner instead of the one inside of the default Bitcoin client. It looks like people using it are getting on the order of 450% performance using it compared to the default implementation on Intel CPUs.

Already am - I just have it tied to slush's pool since I didn't want to wait months for the block to be (possibly) found.

on my amd athlon2 x2(2 cores) cpu i get 2600 khash/s, on the amd phenom2 x6 (6 cores)cpu you will get around 7800+ khash/s, is it worth it? you deside.

my PhenomII X3 gets ~7800+khash/s already on jgarziks cpu-4way, or ultrasofts cpu-miner,
an X6 should get about twice as much.

I'm running an X6 1090T BE, not overclocked and can confirm that I get ~17500 khash/s.

Are you running with the 4way switch? I have the same proc, and I'm getting ~20khash/s with pop's cpu miner.

Oh yes, I am. I didn't realize this topic was about the original client. I must have been skimming too much when I replied.

He must got lucky, or done it a long time ago, when difficulty was a lot smaller. Right now, to find a block with 4000 kH/s you'd have to mine for 1 year and 12 weeks on average.

He started February 9th, and got the block Feb 14th, according to his podcast. That's pure luck.
