I have 4 280X cards.How can I set for letting them work at same time.And the speed only 2300k/s.Can I change number of threads to improve the speed and how can I set number of threads?another question is why its speed will direct gonging down to 60k/s and ask me Whether to exit the batch after running somrtime?

You can start several devices by setting "-d 0,1" in your .bat file (0,1 would be OpenCL device indexes which is listed when you start the miner, yours might be different). The decreasing hash rate is not to worry about, it´s simply a 32bit counter wrapping (reaching it´s maximum value and starts over from 0) it is only visual and won´t affect actual performance. Well now that I actually helped someone for a change I would like to give some feedback to the developer. Currently if/when the miner lose connection with the pool there are never any attempts to connect back again, it would be awesome to have a reconnect feature so we don´t lose any hash time. I know I'm a lazy bastard asking you to implement this rather than doing it myself but it is probably a quick matter for someone familiar with the code ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Also, thanks a lot for your efforts with this miner.

This is quite strange since i didn't mess with the networking code from ypool, but you're not the first to point it out. I'll look into this today (the 32 bit counter is already fixed in the code and in the linux and mac binaries, just the windows binaries still have the bug). Thanks for the support.

NEW RELEASEBuild 5, fixes the following bugs: - bogus hash count after half on hour or so in fast GPUs. Now it report the right hashrate for several years. - Not reconnecting after disconnection. Now it waits 45 secs after every disconnect and tries again. New Features: - counts invalid and valid shares separately, so it is easier to spot problems. Todo: - several AMD optimizations are on the pipeline, but they were not yet mature (too many invalid shares) so they were NOT included in this version. Download binaries and source from the same old place. OSX binaries not ready yet, only linux and Windows available. Binaries link: https://www.dropbox.com/sh/2wv2awwgebpdo0m/STzOU5tlXaSource code: https://github.com/girino/xptMinerThanks, and enjoy the new version.

Any idea why the miner seems to just stop finding shares after a while? I noticed the kh/s going down over time but it was still finding shares pretty quickly, but this morning it was reporting 0 kh/s and not finding shares. Win 7, R9 290 if that helps.
never heard of it stopping finding shares. isn't it a network problem or something? maybe the pool was down. about the speed, the original xptminer from ypool used a 32 bit counter for hashes, but it overflows quite quickly with gpu hashing speed (30 minutes to 1 hour, depending on the gpu). so reported speeds after the first half an hour or so are just bogus. I'll release a fix for that later today. (code is already fixed, but i didn't create the binaries yet). Found this bug, it is fixed in Build 5!

Awesome, keep the updates coming. I noticed that you can include the CPU in the list of devices to be used with your miner, is this efficient?

Not at all. It will use opencl on the CPU, and you will get at most half the hash rate you get with a decent CPU miner.

strange. Couldn't reproduce it here. But this code is outdated, you should use gigawatt's version which has some optimizations i didn't port back yet. (he used vector types for shavite and metis/fugue, and gained some 20% speed). his code is at: https://github.com/llamasoft/xptMiner

This miner doesn't change the GPU clock. You need to use and external tool for that.
