Claymore XPM GPU Miner discussion

[Claymore]

this program causes severe memory leak errors on a couple machines with 7950s and 7970s... not sure what the issue is

There are not memory leaks, just use lower "-hc" value, read "readme" for details.

I just wanted to say thanks @ Claymore for a really awesome miner. I found 3 blocks in the first 2 days of using it. Great job, keep it up!

solo?

No, on ypool. I don't think it can do solo.

Looking at what you said.. if Claymore can do solo, it will be great! ypool is getting too much hashrate

I'm working on solo miner, it will be available in a couple of days.

awww.. any chances of a linux solo (or pool) miner? I dun mind paying for it.

Not realy sure that xpm is the most profitable coin out there anymore since recently multipools are getting 0,008BTC/Mh/day wich is about twice as much what i get from xpm. Can someone confirm that?

What pool? Here is what I see on multipool.us:

Period                                        Avg. Scrypt Profitability
                                                           (BTC/MH/day)
1 day (ending 2014-04-19 0:00 UTC)        0.00516499
3 days (ending 2014-04-19 0:00 UTC)        0.00546087
10 days (ending 2014-04-19 0:00 UTC)        0.00448038

lol he is talking about this:

jup...and with roughly 1mh(2x r9 270) i am getting 2,5xpm on a good day which is 0,005BTC/day.

which is to be expected

@Claymore It's a bit unstable. Any chance of having some simple API so we can check on it and restart or reboot if something is wrong?
In the meantime I'm trying to wrap it in Ruby script, so that I can interact with the shell window while I'm at it and process output programmatically while I'm away. But I have problems with STDOUT redirection. It stops output after the line "xpt: Logged in". Can you help me on that?

It can be unstable at high "-hc" values on some systems and if your cards are overclocked too much.
Anyway, I just use "printf" and "std::cout" for output so stdout redirection must work properly. Do you want to have an option to save "share found" messages to some file so you can check it periodically?

1)Can anyone explain to me why solo mining is more healthy to the network than a pool?

2)When ill be solo mining. all my rigs will work on the same chain/block? or each rig or each instance (each card?) will work on something else? how do i use all my rigs to work as one

that's exactly the same... the argument is purely demagogic (for and against ypool... but if ypool exists it is also because there is a huge demand).
Quite frankly I find the xpm world pretty strange compared to other coin...

How so?

I think the diff is that ppl still believe there is a chance with solo and I think there is, compared to other coins; Most ppl just find a pool to join rather solo mine, except when coin is launching.

Some kind of log file would be great. Write to it whatever you can without much work on your side and we will sort it out.

It can be unstable at high "-hc" values on some systems and if your cards are overclocked too much.

I'm not saying it's unstable. Just a bit I'm using it only a couple of days and so far MTBF is about 12 hours.
Some of the crashes are driver's. That may be because cards are overclocked/undervolted too much. I have 7970/280X and I'm not touching "-hc" or any other additional options. Once I saw out of memory message, once something like an attempt to write to restricted memory (can't remember the exact wording).
But anyway I like to push my cards a bit at the cost of a reboot once in a while. But that makes sense only if reboot comes as soon as worker process hangs. So I need to run some monitor program.

To make it not crash I had to downclock memory

perhaps these are sensitive to memory errors (AMD gpus don't do error afaik)

Once I saw out of memory message, once something like an attempt to write to restricted memory (can't remember the exact wording).

I get both these errors too, downclocking mem to 1300 MHz helps but probably there are memory leaks in the CPU code

Only pro series like FirePro have ECC memory I think.

Downclocking memory lowers performance a bit for me (if those TRT values are any guide).

[slimdim]

at present mining xpm it isn't favorable. from 1 card 280x there are 2 coins a day and it = 0.0039 btc

on any multipool it is possible to receive more

for example - clevermining 0,00657 btc per card 280x...

to too many people became mining xpm

You can check it for yourself with "> log.txt". It outputs first lines till "xpt: Logged in" and then stops. It runs, submits shares, accepts input but doesn't write to log.txt. And somehow saves output in the buffer or wherever and spits it all out in the logfile when I stop it. I'm not a seasoned windows programmer. Is this a known issue (not redirecting STDOUT correctly) for programs running in the shell? Can anybody confirm that?

v3.0 is available. What's new:

- Added SOLO version with same mining speed as ypool version.
- Speedup about 15-25%, depends on card, faster card - more speedup.
- Improved stability for high "-hc" values.
- Removed "-ss 0" mode, now it works as default "-ss 1".
- Added "-log 1" command for logging.

+1 ! I was thinking how would you implement dev fee for solo, what a good solution!

Is it still 10% fee on solo miner. Can't really tell from the readme. But the YPool is defininitly faster for me on the R9 270 and R9 280.

You rock. And I still am doing the 10% was just curious about the solo miner.
