hey people i need to learn asus strix rx 470 4gb cards hashrates ?
i just bought them and now im waiting for arrival.

I don't have an answer for the 470, but a 380 strix doesn't mine as well as a Sapphire 380 by 3-4 Sol/s. Best I can get from the Strix is like 33

[Xardas2014]

It rarely show the hash rates, only that points were it says that shares accepted, is there something wrong ?
Also I got 44-49 on RX480, no crashes so far.
What about the power usage ? Is it same that was on Genoil ?

hit r to get the stats if they don't show up

MSI R7950 Twin Frozr cards are running on average 38 per card. I'm happy. Thank you Claymore.

I'm using s instead, also pool shows that everything is fine

Is perfectly but 1 of the cards is not working at all...

how to fix that?

Part of DevFee problem solved - added -allpools 1 - miner changed DevFee and problem removed,
Claymore - i think what error in your wallet on nicehash, miner gives error because not working on nicehash without workername after the wallet, maybe you forgot to write your workername in the source

Everything is ok with the miner, I have checked equihash.usa.nicehash.com:3357 many times, it works for me and for most of people. But nicehash has paranoid ddos protection, I think it's the reason. I see same thing for my XMR miner when they block devfee connections sometimes. I asked them if they can help somehow, but they don't want to change anything. So if you have this problem just use "-allpools 1".

why are there binaries only? Could maybe make the zec for cuda work on this with the source

I guess, most peepz is now dumping, the price still falling reaches 0.74BTC as of the moment. and difficulty is also increasing. effect of claymore's Best miner :-)

Yeah, I really do not know why people are so happy. Here is the effect of CZM (this miner): profitability dropped by 2. In fact this is the end of profits on ZEC. Maybe it is good for decentralization, but it is an absolute evil for those who wanted (and made) some money on this. Let me explain in some bogus numbers if you like.

Assume there were 3 players that generated 200, 300, 500 shares for 100 coins/day (10 shares per coin), they received 20 (200/10), 30 (300/10), 50 (500/10) ZEC coins. Assume 1 ZEC = 1 BTC. And they received 20, 30, 50 BTC/day.

Now they have doubled hash rate and generate 400, 600 and 1000 shares. Since number of coins per day is the same (difficulty jump up to ensure it), now we need 20 shares per coin. They still create 100 coins/day and should receive 20 (400/20), 30 (600/20), 50 (1000/20) coins. The same amount, but increased power consumption.

But now some lazy newbies started mining ZEC as well, and lot of old cards are now mining too. Let assume they added +20% of total shares. That is we decrease the ZEC profit by 20% and now receive 16, 24, 40 + new 20 percent of share for same 100 coins/day.

Also we all are rich now and start dumping. The price dropped by 25%, and now in BTC we have 20% less. If 1 ZEC was = 1 BTC, now it is 0.75 BTC, and instead of original 20, 30, 50 BTC/day we and newbies receive 12 (16*0.75), 18 (24*0.75), 30 (40*0.75) and 15 (20*0.75) BTC.

Was: 20, 30, 50
Now: 12, 18, 30  and 15 for new players who was waiting for this miner.

And yes, you should also subtract 2.5% fee from this amount.

Net result: 50% real profit loss. Numbers are not real, but the idea is the same. Do not know why people are so happy. I think only those who was not able to build a miner on Linux are now happy since they have come into the game. But good profitability is behind.

Your analysis has some merit... several valid points if you will... but the other huge factor in all of this is the big drop-off in ZEC price.  And while certainly some of that drop is due to the growing supply of coins, it seems likely that another factor is the big problem with many ZEC wallets at the moment.  I alone have seen 2... flypool has not been able to send to "z" addresses in over 24 hours. Luckily, (or so i thought) I am using a "t" address from my bittrex account BUT... bittrex's ZEC wallet system has also been down for over 24 hours.

Granted, I am still pretty new to all of this but it seems that problems like this cause concern, which means that a certain % of people that were so gung-ho about ZEC have backed off on that stance, hence, further lowering demand for ZEC, dropping the price even further.  Hopefully this will get resolved soon and provide a bit of a rebound but at this rate, it may indeed be back to ETH for a lot of miners very soon.

This is a private miner. He does not use public sources.

Is there a version of your miner that will work with my HD 6990 cards (essentially 2 6950 or 6970 GPUs on one card)? And if so, what must I do to obtain it, and set it up for my cards?

The AMD driver site said the newest Catalyst my cards could run is 15.9 (not 15.12). When I ran them a couple years ago, they were mining with Catalyst 14.6 (on a mining OS called PIMP-1.5.4-amd-14.6-r2). I am disabled, and have a limited income, and therefore must run what I have. Thank you.

I have a 6990. Use drivers 15.7

And mine ETH with it with his miner software not ZEC. ZEC will run at 2Sol/s per core so 4Sol/s.

With ETH you will get 13MH/s each so 26MH/s total. Almost the speed of RX480 & 390 just uses alot of power.

You can also undervolt them to like 1.0V to save on heat and power.

Thanks man. Is that with Claymores? Which version? Dual miner (ETH & Zcash)? And, where can I get it? Where to mine?

Appreciate your input...James

@claymore

many hours i use your miner with nicehash.
i don't pay any fee ... sorry for you !

without -allpools 1 it can't connect to nicehash.
with -allpools 1 it try to connect to many pool but nothing, no problem for connection just i see :
DevFee: ZEC: Job timeout, disconnect, retry in 20 sec...

edit : it's ok it work for you now but very long time i'm waiting

[nanona]

Im lovin' it!

Good work again there Claymore.
Biggup!
The difference between v1.0 and v1.1 is substantial

[elgi76]

@claymore

i try your miner with 2 instances, it work fine, same hashrate.
but this give me a idea :
can you make a flag start for choose a config file pls ?
by default config.txt and if i put "-conf config-coinmine.txt" or "-conf config-nicehash.txt" zecminer use my config file.

[AnorakSupra]

Hei, I cant get the miner to use all my GPUs.

Code:

E:\Claymore's ZCash AMD GPU Miner v1.1 Beta>ZecMiner64.exe -zpool zec.suprnova.cc:2142 -zwal AnorakSupra.Rig1 -zpsw x -tt 65 -tstop 81 -fanmin 20

╔════════════════════════════════════════════════════════════════╗
║            Claymore's ZCash AMD GPU Miner v1.1 Beta            ║
╚════════════════════════════════════════════════════════════════╝

ZEC: 1 pool is specified
Main ZCash pool is zec.suprnova.cc:2142

blah blah here

AMD Cards available: 2
GPU #0: Ellesmere, 4096 MB available, 32 compute units
GPU #1: Ellesmere, 4096 MB available, 32 compute units
POOL version
Total cards: 2

And there it just stops and nothing happens.

My setup is as follows:
2x Sapphire RX470 Nitro+ OC 4GB with 1500 strap mod
ASRock H81 Pro BTC
4GB Corsaur memory 1333
CoolerMaster G750M PSU
Using molex powered 1x risers (USB3)

Windows 10 Pro 64bit pre anniversary
Crimson 16.9.2 driver (same problem with 16.11.2 HOTFIX)

Ctrl+C on the terminal crashes the driver. But it recovers.


With the -di 0 flag the miner does its job, with about 37 - 40 Sol/s
And with -di 1 the miner just stops at Total cards: 1 again.

I want to rig up my 12 GPUs, but I am struggeling with more than 2 cards per system. Windows starts to get crashy.  

I'll switch the card which does not want to mine now, and will see what happens.
