Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[marvykkio]

I think the psu enough for 4 x 480 8gb,
evga 1300w g2
and again the psu has 25 days of life, bought it new on Amazon

XMR is the coin to be mined now.. On both new and old hardware.. Price is SKY ROCKETTING..

Maybe you don't have such a sense of humor...
You also don't seem to understand how copyright law works.  It restricts copying, not reverse engineering.

It seems you should learn a bit.
The License file is a part of miner package. Besides copyrights, it also describes what you may do and what you may not. Do you state that you may ignore "License.txt"? If so, that's what I mean when I say that some devs don't respect licenses.

You are almost paranoid about people learning how your code works, yet it's been over a month since I publicly described how to implement a ZEC miner that is significantly faster than yours.

Then why do not you do a miner ?

There hasn't been enough incentive to do it.  If someone offered a large enough payment, I could write a Linux ZEC miner that is at least 10% faster than Claymore 9.2, and probably have it finished in under 30 days.

You can add a 2% devfee just like Claymore does and make much more than 10BTC.

[xeridea]

OK, how much for a 10% faster miner?

10BTC would be enough.

Sure you can

I actually think I could get 25% faster performance, but would only promise 10% to play it safe.
It would be even easier for Wolf to do it given his expertise with GCN assembler, but he seems to be having more fun doing other stuff.

Can Claymore also do that?

None of Claymore's miners (eth, zec, xmr) seem to use GCN assembler, even though people like Wolf and Realhet have been doing miner kernels in asm for at least a couple years now.

Yeah yeah, all talk and no code. Theoretical code makes people no money.  Zec is least profitable to mine now anyway. Theorizing is fine, but is worthless for bashing, and often theoretical speed != reality. If it is as awesome as you say, you would write it.  What is the point of hyping up theoretical vaporware you have no intentions to write, just to try to discredit others? Is your theoretical skill over 9000?

Hi guys
I have a question
Which kind o windows is better for claymore's zcash mining?
I have 5 r9 390x and i want to know which version of amd driver is the best for this work

I am use Windows 10 and don't have any problem with it. For such cards you may use Crimson 15.12

claymore has said from the beginning for someone else to make a miner better than his and he will lower dev fee and/or beat theirs.  So instead of talking a big game, just make it.  Then you can say whatever you want.

You mean you give people a virus to install to their computer.  Make greedy people pay a penalty by giving them a virus. GG

That's a possibility, but by no means a certainty.  ZEC could drop to $10.  The majority of ZEC could end up being minded by botnets, or by big farms running private miners.

I've been approached by a number of people asking me to write a private (and possibly public) miner, so it won't be long before I get the right incentive to write it.

I think the psu enough for 4 x 480 8gb,
evga 1300w g2
and again the psu has 25 days of life, bought it new on Amazon

For me the power supply of 1300W (Antec High Current Pro Platinum ) work with 6 x SAPPHIRE RX480 8 Gb Nitro OC + .

[bittawm]

I cannot get -tt to work on either the claymores eth miner or zcash miner

i have 3 rigs

2 of the m -tt works flawlessly

one my last rig i woke up and temps were at 89 degrees

can someone come up with a fix?

 IMO if you must use windows on those cards, go Win 7 and the Catalyst 15.12 or Crimson 16.10.1 drivers.

Difference between you and CM.  You claim things can be super fast, but say it's not worth it to you for less than X money upfront.  CM makes an actual miner for anyone to use, knowing profit will be made.

High performance code is often not started in ASM, as writing OpenCL or C code is often close enough or same speed as what you could get with ASM, and often gets you useful information for the best way to do things, before spending lots of time writing, and iterating over ASM implementations.  Also ASM optimizations are often custom to each card, which increases time. So while you were all theory from day one (which is fine if you don't plan writing a miner, or just for fun). So CM profit, now you spend time trying to get others to copy CM code, which is obviously quite good, or you wouldn't suggest it, because you know you missed the profit window.  It's silly to mine ZEC with AMD now on many cards, better to Eth or Monero, so good luck selling a miner 3 months late.

how many sols on 270 AMD ?

Win 7 64 bit + Crismos 16.10.1 or 16.10.2 ( don't forget about 6gpu_mod) it works for sure!

Can you miner be faster than the  private miners?

I'm running a Rosewill Photon 1050 with 5 cards currently! Been going about a week with absolutely no stability issues, etc.

1333mhz core, 2100mhz memory clock with -30mV under keeps them cool and has generally run well for me. I'm using 16.11.5.

So in short... Yes, you could very easily do like 6 cards with your 1300w power supply.

     I'm a bit late to the party, but I'm getting 250-255 h/s on Sapphire Nitro+ rx 480 OC 8gb cards totaling 1750 - 1785 h/s (stock bios). According to GPU-Z, each card draws an average of 115w (core), but shows intermittent spikes no greater than the maximum specified power consumption for the card (225w). Running Windows 10 on both rigs with crimson V. 16.11.5 (this is the most recent update, that I've found, that will recognize a bios mod).

     I could do 8 cards on the MSI Gaming 5 (7x PCI-e + 1x M.2 ---> PCI-e adapter), but the rig lost some stability once I went over 6x GPUs, even with enough power. The Gigabyte ga-z97x Gaming 7 can house 7 cards (6x PCI-e + 1x M.2 ---> PCI-e adapter), but as I said before, stability seemed to become more of an issue with more than 6x GPUs. Each rig has been running for about a week without any resets or crashes. Just in case the miner or machine does crash, I have made some simple .bash scripts to restore all of my settings and programs upon reset. I have also used the Windows Event Log and Manager to reset in the event of a freeze crash. So all in all, I plan to have 6 cards per rig and I'll probably have to add another PSU to the first rig when I reach that point.


*DAS IMPORTANT*

     When it comes to power supplies, it is almost ALWAYS cheaper to buy 2x units and an adapter, than it is to shell out the money for even a 1200w PSU. My EVGA Supernova P2 1200w Platinum was about $220 (on sale), but I could have bought 2x  700w-850w PSUs + a convergence adapter for 2/3 the price. Also, Never purchase a PSU with a rating less than gold; it will save you both time and money in the long run.

*This is a great PSU reference guide. https://i.imgur.com/tgrbCnr.jpg

     On a final note, I am aware that there are mods to allow for more than 4 GPUs on Windows 7 and more than 5 GPUs on Windows 8, but save yourself from a giant, time consuming pain in the d!<k hole and just kiss the ring and buy Windows 10. I can assure you that the $100 is worth it.

I like your analysis

But if I were you and had 7 gpu's without being able to make them work good together I would probably do 2 things:

1. Sell only the 7th Gpu and make a very efficient 6-GPU rig which is quite easy skipping a lot of costs with the double (mobo, psu, risers, case, RAM, CPU)
2. Buy 5 more cards and make 2 very efficient 6-GPU Rigs
