You're right, the power supply design is different and could definitely vary in efficiency. A more even comparison might be to see what the power usage of your board is when mining at 125 MH/s. Could you test that out? I wouldn't be surprised if your design was still more efficient, but I doubt it would be 50% more so.

The design of the initial release required 5.9W at 128 MHz. (release number 110826 on http://www.ztex.de/btcminer).

If your 1.2V voltage regulators are becoming hot (IMHO you are using two), they are at least a major part of the problem.

Thanks, clearly you are getting better efficiency. The 1.2V regulators are not hot on this board, but they are slightly warm. According to the datasheet, they should have roughly 90% efficiency in our configuration. I doubt your regulator gets much better than that, if at all. Your advantage probably comes from the FPGA code, then. Interesting! I'm curious to see what you're doing differently that gives this better efficiency.

So wtf... have you forensically analysed the code yet? Cheesy

PS: our board looks cooler Tongue

Looks interesting - I'm guessing this will be a closed source release though?

As stated in my first post it will be open source (github) so anyone can review the code and contribute, but also to ensure the code is clean of any mallware.
We're talking about a financial program, so security is key, and you would want to trust the program that handles financial transactions on your Mt. Gox account!

tl;dr
Open source all the way!

Hi Deebug,

It sounds like you have the right idea so far. Keep updating this thread, I'm quite keen on getting my hands on those bins to give it a try. Are there any instructions on how to compile yet it?

Nope, sorry.  Gzip is a streaming compressor.

And in general, GPUs aren't as memory limited as you are thinking.  The typical highish end video card that we use has more memory on it than a generic server from a couple of years ago.  Any change that makes hashing memory intensive enough to stop GPU mining will kill the network by forcing nodes to drop out.

Good job Gavin on how you handled this.  Nice to see at least one side of the conversation remained diplomatic and respectful.

I would subscribe to an email newsletter about this app if there was one. I'm very happy about it's development. Wink

Madhatter and nanaimogold are obviously scumbags.  That doesn't really help your case though, Bruce.

I think it'd be best for Bitcoin if you stepped out of the spotlight for now, and gave others a chance to step up.  We need a chance to diversify and decentralize the Bitcoin "PR department".  Just take a break from your promotional activities for a little while and wait for the air to clear.

Minor bug report.  If you start the program and it's not maximized, then you maximize it, the chart won't scale to fit the new size.  Chart scales fine if you exit the program while maximized and then reopen it.  Let me know if you need the IDE Log

In my copy of the app running here: I get charts under the Forex folder in the app. I don't get any charts under the bitcoin folder in the app.

I have deleted my profile as explained earlier just to be sure it's not my install.

Please advise.

PS: I'm excited about this app. It looks shweet so far!
