ok everyone so just to restate, coin-e DOES work, i just sold 2.5 bitcoins worth and have withdrawn sucessfully

Yeah. I sold 100 at .011.... I wish I had waited. I'm just watching the price go up and up since then, it's at .014 now. Crazy what this coin is going for.

Hi all, here are some quick tuning tips I've found.

So far I've been able to take:

680 GTX from 40,000 khash to 120,000 khash
780 Ti SC from 130,000 khash to 190,000 khash

And I've successfully found blocks.

Best settings I've found so far on both the 680 and 780 "K1024x32" - Increases 15,000 khash from most other settings tried
Set maxcoind.exe CPU affinity to at least two less cores - Increases 15,000 - 40,000 khash when a few cores aren't in use
Leave a Chrome browser or simple video/flash game running - Increases 50,000 khash or more if GPU is stepping low, crude solution till I figure out a way to disable stepping/power savings
Overclock yields more khash, no brainer

If you get ANY errors starting up Cudaminer, compute capability, exceed warp, out of memory, etc., you are not mining correctly! This will produce wild results such as millions of unexplained khashes.

More to come, busy days for me, but I'll try to get a basic guide out for cudamining and tweaking maxcoin.

I'm getting about 105000 with gtx680 but the card shows only 80% power usage

Hey guys can anyone kind enough show me an example of a code for solo mining. Still trying to get my head around this one.

As best I can tell the 1gh patch simply uses OpenSSL for the stratum sha256 calculation. Here is the patch for Cudaminer although 1gh is still funky, they hardly ever accept shares even though you're cranking away forever. Also keep in mind this make break it for other stratum (ie. maybe it's 1gh that is broken, not cpu-miner).

Code:

I went to a pool (rocketpool) this morning (it wasn't really open, they are testing), and my very rare share were accepted.

Great thanks to the guys here who helped me setting up all the stuff needed to mine Maxcoin, and to Christian for making this great software

Anyone know how to send maxcoin to a deposit address (ex Coins-E) ? I have checked cmd maxcoind help but not very clear how to set the send.. command.

Thanks

let me propose an improvement. sha256d for anything but keccak, and SHA256 otherwise

Code:

/* Generate merkle root */
if (opt_algo != ALGO_KECCAK) // CB: fix for
sha256d(merkle_root, sctx->job.coinbase, (int)sctx->job.coinbase_size);
else
SHA256((unsigned char*)sctx->job.coinbase, sctx->job.coinbase_size, (unsigned char*)merkle_root);

Does cudaminer not work with 1GH out the box? I either go forever without a share or when I do get a share it's rejected. 100% of the time.

For those of you trying to mine on ypool

Go to How To, Click Doge, Download the xptproxy

Launch the proxy. use the address http://localhost:8332 with all your configure for cudaminer etc.

It should be able to connect and mine

Basically download this:

http://jhwork.net/ypool/xptproxy.zip

then cudaminer blah blah -o http://localhost:8332

bumping this for visibility.

Just FYI, this doesn't work for MAX as that proxy is scrypt only.

Christian, is there a problem with the windows code at the moment? I can't get it to compile with VS2010 for the life of me.

I'm a bit confused.

I have a GTX 560 Ti

With -l f25x23, I get 294501 khash/s, but the GPU is hardly in use.
With -l F1536x16 I get some out of memory errors at the start, but it works, giving me 75284 khash/s. The GPU is using about 80%

Is the f25x23 doing it's job?

Thanks

No

try 1024x16

It gave me just 18893 khash/s

yes. the keccak support was a rush job, so it has a few rough edges.

Thanks, but I didn't get the answer. Should I use f25x23 or F1536x16? I have a suspicion that I should be using the one making the most use of the GPU, right?

Do you people get a yeah! when solomining ?
Mined all night with a gtx 670 at 110mh/s and nada :/

actually during that night, not that much... I totally missed the launch with the wallet which didn't want to connect...
Got one when I was trying to figure out if it was working, another one two hours later... but this morning I got 2 in 30 minutes (might not see any during the whole day now...)
