I noticed something strange today (herr... yesterday...). I was running on MRC in x64 windows version, at some point I look at the graphs from msi afterburner, the gpu was running all the time at 98% not at 99% as usuall.
I went back few hours later to the x32 version, then I had 50khash more and everything was running as usuall at 99%.

Another thing regarding the values given by the autotune, they seems to be off by a factor 2 (on the latest version... I was trying to find a config which could beat the Z one I use...

Another question regarding the lookup gap, to which N factors this one gives advantage. So far I only saw the effect on YAC.
I tried changing the L value for MRC or QQC, but that does'nt have any positive impact...

Suffered a slight hit on khash with latest update today using the x kernel. Not sure why. My 460 V2 was at 130 khash dropped back to 120khash. My 660ti dropped from 183khash back to 180 so im guessing its more Fermi related. All in all minor stuff as for some reason I haven't noticed the stratum receive line failed error I would get occasionally after todays update.Anyways Keep up the good work it constantly seems like a awesome work of art. Someday Nvidia chips will smoke the crap outta amd for mining.
Edit: Noticed Chips are only utilizing 97 percent.

Can I call shenanigans on that 2014-01-29 660 TI added to the spreadsheet? I find it very unlikely that a stock 2GB card running the 12-18-2013 build is going to get 409Kh/s (79Kh/s faster then the top 660 TI)

Question of the day: What to mine with my nVidia cards?

Yacoin -> this coin is falling (failing?)
MRC -> no luck with solo mining at all. Trying a pool now (mrc.easy-mining.net pool seems to be fixed at last).
VertCoin -> who is currently into this coin? if you are, why?
middlecoin -> the DOGE rush is over, right?

I think what would really be helpful is a profitability calculator for various scrypt-jane coins, taking one's hash rate at different N-factors into account.

Wow, Litecoin difficulty is on a rollercoaster:
http://bitcoinwisdom.com/litecoin/difficulty
I think this is a good example for the influence of DOGE and I think MOON, which both probably are over now?!?

Oh and forgot to write, I don't see any difference in Build 113 with Kepler GT 640. Neither in scrypt (litecoin) nor in scrypt-jane (yacoin).

Doge prices are going up and dowj still but the difficulty has shot up.

I do think we need some sort of profit calculator as things seem very hard to choose whats best at the moment

Right now, the MRC seems the most profitable (in terms of volume and value) with my one card setup (need a new psu to add my old gtx660 oem)... although the market place where you can exchange them are not so good...  and the price is going down.
The Hashrate for the 780ti is around 1380khash/sec.


I mined vertcoin last week, but this week I would get something like 20/day (390khash/s), not worth it.

QQcoin seems easy to solo mine however the reward can be anything between 4 and 40QQC.
I get around 600khash/sec and from the calculation I made, I should get 1 block every half hour.

Is there any new scrypt jane coin with low N factor around ?

I will download and give it a test :-)

Edit: ok so it took 7 attempts and 3 downloads to get the latest build to compile. Bare in mind I have compiled every other release in 1 attempt. It was giving different errors constantly and even sometimes doing nothing

Finally got it to compile and found a drop in performance.
4.77khash/s for the latest
5.04khash/s on the one I built around 12 hours ago

Thats on yacoin with the same configuration as I posted earlier. It was not left to autotune I just ran the settings I did earlier

For scrypt-jane I am seeing mixed results. GT 640 (Compute 3.5) seems a little slower, GTX 780 TIs on Linux slightly faster.
Maybe I can later offer an option to switch between these two (totally different) memory access schemes to the scratchpad.

I am also wondering if you guys still see non-validating shares in conjunction with the lookup gap after this change?
 I can't see much activity when solo-mining, but the pool miners will notice.

Christian


Hi Christian,

I still don't have time to research the profitability of scrypt-jane coins, so I still stick my cudaminer to scrypt coin. Earning steadily over 0.02 BTC/1Mhs daily now (as most as double as middlecoin & multipool co&). If you don't have time to research the new coins, just point your miner to pool.chunky.ms port 6666. I'm currently supporting and working with the pool owner to improve the profit calculator for the new coins.
Check pool.chunky.ms for more information  Wink

In what do we get paid out if we use that chunky pool (the 6666 port one)?
It's sadly not mentioned in the FAQ there.

It is currently in the beta mode, sorry that I forgot to mention that.
You can setup automatic payout every coin which supported by the pool to your wallet, and then point your miner to port 6666. It will automatically mines the most profitable coin. This kind of service is not new, I know. The reason I like about this pool it is because it supports new coin and the new coin are in most case very profitable before the multipool & co knows about it Wink

How is defined exactly the profitability ?

The pool wont be able to switch between scrypt-jane and scrypt so you have to pick one or the other to do. As their different algorithms

cudaminer cannot even switch to a different N-factor coin, as one currently gives the N-factor parameters (or coin name) at program launch. Furthermore, switching to a different N-factor would require a complete re-initialization of all memory buffers and require a different set of kernel launch parameters.

hmm, so I do not think multipools for scrypt-jane are currently feasible with cudaminer.

One would have to define extensions to the stratum protocol to signal different startT, Nfmin/Nfmax parameters (or alternatively the current nfactor) and redesign parts of cudaminer so it can switch the Nfactor at run time.

I didn't say that this pool is scrypt-jane multipool. It is pure scrypt multipool like many others. But they support new potential coin IMO. And I only report my experience.

@Christian: yeah I need to manually kill cudaminer in all of my machines and restart it again. At first it is pure pain in *ss but I have written a bash script for this task, so it's ok now. And I always wait 5min before start cudaminer again, for safety.

Only the pool owner knows. Every pool owner has his self-made profit calculation method. But in general I assume it is all the same like coins mined per hour * current exchange rate. Of course many other factors are included. I even have my self-made profit calculator.  Grin
