I've got a 7950 and an R9-290 I could toss at it.  Looks like I'll get around 12 Mh/s.  Just toss me settings, point and shoot.  Not exactly the most valuable service in the world so, don't worry about it, future consideration ("There will come a time when I may ask you for a favor...") 

No idea, but I do believe 3.7.3 is the last version with scrypt.  I'm using this fork...

http://cryptomining-blog.com/1835-yet-another-performance-boost-of-cgminer-3-7-3-for-heavycoin-gpu-mining/

I've really gotta learn Opencl programming sometime.

Well I just had a big fat "D'oh!" moment.  Nice of them to totally change the intensity settings on that version of CGminer.  Dynamic adjustment, kills 2'nd threads, intensity with minus settings, how could I have missed that. 

Dropped the volts a bit on that card and man, what a difference, far more than you'd expect, non-linear in fact.  Check the before and after.  Going from 1.25V to 0.988.



From 115 watts down to a mere 62.  Now hashing comfortably at a more respectable 12.35 on the 7950 and 19.11 on the 290.  Both at stock.  Not pushing it with this one because hey, sometimes it's better to walk, not run.  Best cover of The Ventures "Walk Don't Run" you ask?  Why it's by the Pink Fairies of course!  Yet another British band who picked their name just to get into fights.  From the album 'What a Bunch of Sweeties'.

I grabbed a 160 Mh/s X-11 rig today because Start was high on the profitability scale, going up, difficulty going down, yadda yadda.  That big rack of cards churning away managed to mine an actual whole DOLLAR in the three hours I had it.  Yeah, it's possible, with the right breaks, and the right connections, line on hardware, lotta other things.  When the smoke clears though there's gonna be a whole lot more folks who lost money than made it though.  As with the gold-rush though, the real money is in supply, equipment that is.  I expect I'll be getting wicked deals on video-cards that people thought they bricked (without knowing a few un-bricking tricks) and thought they fried.  Right now I'm using this tasty R9-290 that I got for $200 Canadian because well... when I fired it up I found it was idling at 80-90C!!  Now I have trouble even getting it to hit 75, overclocked to 1200/1800.  $200 for a $600 card.  Then there's this 7950 I got last week for $80... "bricked"?  NOT!

Surprisingly though, people actually DO run software on their laptops.  The program I pointed to manages threads and cpu usage.  You set min and max CPU percentage, threads, even targeted hash-rate.  All designed so that the n00b isn't going to cook their chip.  Believe me, when it comes to keeping chips cool, I know what I'm talking about.  As for mining, most people do it just for fun, just to get a piece of coin to play with and practice trading.  Actually, after looking at the numbers at present, MAGI is just a bit too unprofitable.  Now here's an interesting coin...

https://bitcointalk.org/index.php?topic=778322.0

Now here's the thing... As you can see by buddy's numbers there, 7 Kh/s/thread, GPU's usually  hash around 500-1000 times as fast as CPU's, give or take an order of magnitude but who's counting.  Now although there are GPU implementations of the Quark algo, GPU programs are only about ten times as fast.  That kind of even things up a bit.  I don't think anybody can fool themselves into thinking they're doing this for the money, unless they've got a huge farm or something.  We all know it's for pennies, but it's fun, and edumacational.

Speaking of which...  Noticed this revived thread yesterday.  Noticed the net hash-rate at about 10 Mh/s and jumped right in, after I checked to see if the blockchain was working of course.  So yeah, could use some hashers?

Mining.  I got the best results by far, no contest, with kernels compiled with the latest 14.12 and 15.3 files.  Worksize was a biggie.  Best with 256 and -g 2.  With those I got a solid 18 Mh/s on my R9-290 at stock settings of 980/1250.  The 7950 though is another story.  Oh the hash rate is there, in a big way.  Problem is, even on it's lightest settings it runs like a thing that is running way faster than it should.  It'll hit 12 Mh/s and then the VRM temps keep climbing.  It doesn't have the volt-mod on it right now but regardless, stresses it something fierce.  Since I'm back to this algo I'll have to go over it again, power settings and the like, but if anyone else has some knowledge of this algo, settings, etc etc, could use it.  Thanks.

Oh c'mon, let an overly polite Canadian show you how it's done.  ;

Yo Adriano!  There are indeed coins that are for CPU mining only.  Best of these is MAGI, and one of their crew has just put out a program which will make this a breeze for you and also prevent your machine from melting down.  It's called Sweet Spot and manages the MAGI miner.   You can find the latest version and instructions here...

http://xmg.makejar.com/

The main thread for MAGI is here...

https://bitcointalk.org/index.php?topic=735170.0

By now you've probably realized that people are using some fairly heavy hardware to mine this stuff, CPU and GPU both.  I just did a quick benchmark of the X11 algo with the latest CPU miner and got twice your hash rate per thread, and I've got eight of them.  Still, no reason not to use that idle power and this package makes it easy and safe.  It's good to use those idle cycles.  If we don't give our computers something to do they just sit around thinking of ways to kill us.

As for your Nvidia card, there are algos and programs that they do quite well with.  Tell me what model you've got and I'll point you in the right direction and get you started.

So I guess one person owns this thing.

Gah!  YES!  Usually they're higher.  Check the seating on whatever you're using to cool that sucker.  They'll take high temperatures, everyone says that, but not everyone has actually seen chips 'n' shit flow off a board like warm butter.

Oh that custom stuff, does run don't it?  Well if you've got the scratch it's good for the economy. Personally I don't, and I've got this as a poster-sized print on the wall.

I don't know just how much more performance you can get out of a custom block setup but I know that the Gelid solutions shown here does an absolutely great job.

 I've got two of them and they'll keep even 7950's out of trouble range.  Again, the problem is never the GPU itself, it's always the VRM's.  Right now I've got Heaven 4.0 running and despite the last fan/sink mod my temps are 45C, and 53/49 on VRM's 1 & 2.  Now that's great, because I was fighting an over 20C difference in all cases, like my 7950, the 6970's, etc etc.  So I guess I'm done with this one and it's now time to take some pics.  Here's somebody going absolutely mad with the sinks.  Total over-kill and about 80% of em doing nothing but he's happy and that's fine.  Gotta love it...

Here's something you could try quickly, a negative value for powertune.  See if it'll still run with those clocks and -20 or -50. 

Ok, looks like a few people here so I'll keep it public.  Hopefully learn something myself and get a tip or three on bioses for this card.  So here's what's happened with your hash rate.... but first... you'll need an important tool, best damn info tool I've seen in decades.  AIDA64.

http://www.aida64.com/

http://www.guru3d.com/files-details/aida64-download.html

Get that and get real familiar with what's behind the first tab, Computer, Sensor.  You'll see a lot there that you'll need to know.  Specifically, there is not just one temperature on your GPU, there are three listed for these cards.  There's your shader, the chip, and then there are the all-important and harder to cool VRM's, Voltage Regulator Modules.  Here's a picture of the layout of the R9-290 via Overclock.net.  GO THERE!  Haunt it!  Live there!

http://www.overclock.net/f/72/ati-cooling

So here's what's happening when your hash rate drops.  Basically you're running up against a power limit, threshold, and it's throttling back.  You can see how many watts your card is pushing in that sensor log, right at the bottom along with all the voltages for your card.  We used to just "push it till it moves" but that's changed with the R9 series.  To get my stable 1170/1350 I used Afterburner to set Core Voltage at just +75.  Then I nudged it back to it's next slot at +69.  I'm pretty sure that the next notch is crashola.  Try this... Set your Core Voltage at +100 and your core clock up to say 1175, whatever you know it'll take.  Hit Detach on the top right panel, now you can see all the gauges.  Start up Heaven 4.0, windowed, and let it rip on Extreme.  You should see it go for that clock, then throttle back.  Check your wattage on Aida64, there's your power limit.  As you drop that core voltage you'll see it throttle less and less.  Now you should have enough to find your highest clocks for mining whatever.  Just start up SGminer, find the balance.  I'm going to have to be a bit abrupt here because I'm totally exhausted, three days up, and crashing hard.  This should give you a good start though and essential tools.  By the way, the way I get my cards to run as cool as Miles Davis is by fitting a CPU water-cooler on them, and there are some real cheap ones like the Cooler Master Seidon series which have mounts that are absolutely perfect for this.  Check the spacing on these screw holes...

Dunno why this went UP in price, because it was the first and cheapest liquid cooler I bought years ago, for sixty bucks Canadian.

http://www.memoryexpress.com/Products/MX42382

Keep an eye out for a used one you can snap up cheap.   Cheap... I TOTALLY lucked out a couple of years back and scored not one but TWO Thermaltake 2.0 (or 3.0, can't tell) units for $22 Each!  Mounts for them are also very easy, couldn't find a picture though, sorry.  Why so cheap?  Oh, they had the wrong firmware on them.  Oh snap, what a... nothing really.  Really gotta update these pictures, show the mounts and all, later, after sleep.

7950 @ 1200/1600, and never over 50C.  G'night!

I'll move this to the PM side so as not to flood this thread.  For the record, just remounted a fan and added a few heat-sinks which took care of a few degrees.  Here's my 290 hashing Ziftr at 4.83 Mh/s, 1170/1350.  Check the temps.



Boo-Ya!  Getting 26Mh/s with M-G as well.

OUCH!  Yeah, I'd say that's running a bit hot.  You gonna be ok with that or could you use a hand?

Still getting a few hardware errors, just dropped the intensity to 17, see if that helps.  Um , nope.  Trying X64, nope.



Also, can't even think about boosting the clocks without crashing display drivers.  Too bad, this 7950 is a beast, I've run it up to 1260/1800.  Also this... but that looks like the shitty volt-mod bios I tossed in yesterday.



7950 & R9-290.  -g 1 -w 256.

Edit:  Also this.  I've been using the compiled bin files because earlier I got this error when trying to compile from scratch...



Now I've updated drivers and installed the 3.0.whatever beta SDK, still get that.  Relevant?  Dunno.

Ah shit, I stand corrected.  Had a window obscuring a slice of another window and blah blah zeros are a bitch eh.  It's only a few orders of magnitude, only a few.  

Yar, I'm out.  At least I've got the knowledge that dev has a shit Quark kernel.

I JUST started mining this oh, ten minutes ago and blocks be flyin'.  At this rate I'll have one of those awful 10,000 coin instamine blocks in... well I'm too damn lazy to bother.  Ching!  Ching!  Ching!  And there's another one.  And another.  And another...

Well I see that I have and I shall!  Thanks!  And in return (well not really, I'd have done it anyways) I'll give you word up on the best sgminer settings.  First off, if you've been doing this for a while your mining directory is a litter of directories of different versions of this and that, updates and upgrades, etc etc.  I found that I had four different quark kernels.  Turns out the only really good one is the very latest, the one running 50k or so.  This one must be compiled using the 14.8 version of the opencl libraries.  There's also a huge difference with configurations, far more than with most coins.  You really want simply worksize at 256, one thread per GPU.  -w 256 -g 1  With that I'm getting

7950 @ 1000/1250 - 3.35 Mh/s -I 19

R9-290 @ 1000/1250 = 4.60 Mh/s @ -I 19

Users can grab an archive of all the opencl versions from here..,.,

http://cryptomining-blog.com/4519-getting-the-optimum-mining-performance-on-amd-gpus/

I'm also uploading that archive to dropbox right now because it is listed as an untrusted site by Chrome, no doubt for all the VIRUS software it has on it.    Kernel and 14.8 files here:

https://www.dropbox.com/sh/97iq9eeb1q0e7fw/AAAESeIxC29idraF7yzdTWz8a

Add --no-extranonce for some extra speed.

And it now looks like said coin has gone belly up.  Oh well.  For a while there I was relevant!    Sooo.... what to toss the hash at.  Well there is this one rather unassuming little coin that's been around for a while now, and I do like quarks... Actually, you could use a bit of support right now.  One BIG hasher, but not enough little ones.

Well now, ain't we looking flash and spiffy these days!  looks great!  Saw the new thread (or new-ish) and had to stop in to see what was new.  Awesome, it seems, is new.  I love the fact that the GPU implementation doesn't have that 1000:1 ratio of other algos, that's huge.  I'm getting 730 Kh/s or so on six cores, boring vanilla speed because my water-block mount had a problem (4.0 Ghz, ewww!)  The cards are doing 2.5 Mh/s on the 7950 and 4.15 Mh/s on the R9-290, stock.  So you've got a gpu coin with a dash of cpu.

I'm glad you've got a good pool of miners right now because I'm kinda 10-20% of Tecoin's hash right now.  Was down to 165Kh tonight, 40 of which was mine.  Blame the dev!  No flash graphics, no completely unrealistic projections, no absolutely ludicrous claims, and no "Turboencabulator" style financial bullshitspeak.  Go figure.
