You must have low electricity price.

they are pretty good I have 2 of them.  price was right

just I was about to give up on ZEC... this happens.... well looking forward to see how much more my 480s and 390s can run.

my powercolor red dragon single fan  470 4gb also came with samsung ram. i was surprised as this was the cheapest 470 i could find at the time 2 weeks ago ($159 with instant $10 off), also came with hitman game. got it at the egg. runs at 1300/1700 at -50, 208 sols.

havent modded the bios yet but when i switch it to eth/xmr ill mess with it.

 Depends on your hardware and your power cost - for me right now the ONLY cards I have that are more profitable on XMR than ZEC are my GTX 750 Ti cards - and that's only because they are in XP gaming systems and nothing but XMR is AVAILABLE for them to mine.

 The links in Wolf0's XMR CPU miner thread were dead last time I checked, though I DID ask him to look into that and he might have gotten them fixed sometime this week.
 He has also stated in the Claymore XMR GPU miner thead that he doesn't think there's much if any code improvement possible for XMR for the RX series.


 Last comment I saw from Claymore about his ZEC miner was a "10% more improvement" estimate with no context on what specific card(s) he was talking about - but mostly likely the RX series.

Is it more profitable for the R9 390 as well?

For anyone interested.

The newest batch of Sapphire rx 470/480 4 gb nitro cards now come with Samsung ram.

 He's already stated there is still some room for improvement - just not BIG ones like the previous versions.

 


 ZEC profitability has taken a major hit due to the continuing price drop - but folks move over to ETH and drag it's profitability down from increase in difficulty, so they're staying close depending on your specific setup and power cost.

 It's "the basket" effect, been there for a couple weeks or so to a noticeable degree.


 Profitability on both has been dropping enough I'm starting to shift my 1070 rigs over to their original intended purpose, as the profitability on THAT is now getting very close.



 I'm going to be curious to see how Ryzen does on XMR - current AMD CPUs don't seem to do very well per core.

do you have a link for a xmr  cpu software?

Yeah, I just ran my actual numbers through that calculator and was shocked to see ZEC only about 15-20% less profitable to mine than both ETH & XMR, both of which show exact profit of $2.39/day on my 4x470 strop-modded over-clocked under-volted rig.  Either that site is whack or something major changed with difficulty, because that gap in profitability actually narrowed vs the last few days despite ZEC falling another ~$4 in the last ~24 hours.  Yes, ETH and XMR are down a bit but not to the extent ZEC is, so must be something with difficulty, probably driven by more and more people changing from mining ZEC to 1 or both of those 2 coins.

Personally, I still have my 4-card rig on ETH and 5-card rig on XMR, but spent some time experimenting with both CPU & GPU XMR mining today.  This is probably known already but what i found is that the strap-mod for the MSI 470s is definately much more important for XMR than it is for ZEC.  I can only get my non-modded 470s to about 580 H/s on XMR, while my modded ones did 690 straight away on a test run over from ETH for about 2 hours.  So tomorrrow I will likely take a crack at getting those other 5 470s bios modded as that will likely get me about the equivalent of another GPU's hash-rate on XMR.

One of the cool things about XMR is that it can still be mined effectively with CPUs.  I have 3 CPUs on it now and am getting close to 900 H/s total, which amazingly pencils out to a better hash per watt rate than even the modded 470's.  This is actually a good thing for those of you (I think there were a few on this thread) that bought/build some higher-end CPU-based rigs when ZEC was profitable to CPU mine in the first couple of weeks.  My experience on all 3 PC has been excellent running Claymore's XMR CPU miner as in most cases, you will only use half your available threads, leaving plenty of power to do other things.  In fact, my 6800k-based rig is capable of running 4x470's on ETH (110 H/s), 7 CPU threads on XMR (350 H/s), 10GB HDD mining Burst, & 4 threads dedicated to writing new Burst plots... all simultaneously.  I guess that's the benefit of having 12 threads with 15MB of cache.

All those rigs are on a single 30 amp 240 volt pdu using 14-15 amps.  I have 8-10 amps to spare.

My home was built in 1970 it had AL wiring not copper.

In NJ YOU CAN WIRE YOU OWN HOME.  You can't rent the home you have to live in the home.
So back in the nineties I wired the entire home in copper.
I did every circuit except for the AC which was copper.

I hired a licensed electrician to remove the old 100 amp box and put in a 32 breaker 150 amp box.

The new box has two 30 amp 240 volt breakers I put them in for the garage shop.
I used to build speakers and had a lot of machines to work wood.

So when I stopped building speakers I had two 30 amp circuits doing nothing.

I could run 48 amps of miners on them.

But the wife would kill me!

So yes I added wiring.

Phil, did you have to rewire your garage to get that much power in there? How many circuits do you have?

I'm struggling with my 6 card rig. Makes the lights flicker 

According to whattomine.com ... ZEC is still up there.

So I left the 390s to continue selling ZEC hash at Nicehash for BTC.

I made a handsome sum of profits on Philip's previous ETH tips.

So I will buy some ZEC on Polo today 

Hope it will be a Merry Christmas present and enough funds to get a unit of that Panda Miner!

I am sticking with zec until Jan 27 2017

I am now holding about 12 coins  and I am buying as well as mining them.

I see a big pump soon.

I was fortunate to be mining at mmpool.org  we are a very small btc pool  that uses a complex interesting payout plan.

The pool is so small we take 2 3 even 4 months to hit a block.

But we hit 45 hours ago and I got 2.4 btc  So I do not have to worry about holding my zec.

I am winterizing my gpu/garage setup  as we had 4 inches of snow today


this rack can hold six 4 card rigs  note the hp pavillion on the lower left that is seven rigs.



three rigs  using 11 cards




and finally  my rack in the dark looks very nice

the good for this rack is 24 msi rx 470's
on 6 biostar z170's

I have 16 msi rx 470's at the moment
on 4 biostar z170's

300 for 480s?  aren't they at about 200-220 now?  Everything i have seen and heard indicates that there are future improvements possible but certainly not anything in the range of 50% or more.  Unless Claymore has had a major breakthrough in the last few days, I thought he was talking maybe in the 10% range over 9.1.  Once again, unless ZEC starts going up instead of down, it seems fruitless to try to suck 5-10% hashrate more out of a coin that is already about half as profitable as both XMR and ETH.  I think only Claymore himself probably knows which one of his miners has more room for improvement between XMR 9.5 and ZEC 9.1.  But most certainly, if ZEC continues its decline, it won't matter if he can even get 20-25% more hashrate out of it since it will barely be (if at all) profitable to mine.

You would be 100% incorrect. He has already stated there is another speed increase coming. Sure we're reaching close to the end but some more can be squeezed.
I heard the theoretical limit of a RX480 is around ~300 h/s.

At current prices and hash-rates for each, Claymore would have to improve speeds on his ZEC miner byt what... 65-70%... just to get it back to even with XMR as far as mining profitability goes.  And I think we can all agree that is not going to happen.  The fact it, as ZEC prices continue to drop, people are switching away from it every day and going to ETH and or XMR.  Given this, I would expect to see Claymore re-route effort towards XMR 10, but who knows. His dev fee is actually higher for XMR btw.

On the other side I'm 100% sure that Claymore's ZEC miner reached the plato. You cannot get more than 2-4% of improvements more

 I'm not going by the box.

 9-)



 As far as Claymore upgrading his XMR miner:

 1) It's possible it's mature enough code there is no significant upgrade that CAN be done.
 2) I'm 100% sure he's making a lot more out of his ZEC miner, and as that appears to have some significant upgrade space remaining, it's drawing ALL of his attention right now.


Perhaps in a month or three when he decides his ZEC miner can't be further upgraded, you might convince him to look at the XMR code again.
