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

[auctioneeeeer]

Again: dual mining is not possible for ZEC because it uses both GPU cores and memory intensively.
About new version: it takes more and more efforts to achieve more speed, so I cannot release new versions every day now. Also don't expect +50% speedup anymore, only 15-30% is possible in total.

Claymore, have there been any specific RX 4xx optimizations?  It feels like the gap between 290x is quite large on ZEC vs. ETH.  Keep up the good work, your fee is worth every BTC

Figured that might be the answer. Or simply that it's sort of pointless due to memory congestion to this point where mixing the algos to this point that dual use offer to profit increase over single algo mining.

Also don't expect jumps as precious. I would expect there is maybe a total 30-40% optimization left in Zcash total looking at power usage and Mem bandwidth. And that's probably only true for high end cards such as 290x390x over 470 due to hardware architecture.

I'm also not an idiot and realize that if you can make extra money pre-runninf a private farm for a while you will prob take the extra paycheck. I don't even think it's unethical.

Not to mention any further optimization will come at cost of power usage and CPU time.

I personally think the next "wave" will be if someone drops the some on equihash ASIC. But that's prob 10 months away and $5 mil. Possibly FPGA before that but not "life changing" from what I can figure with Xlinix and dram modules.

Thank you for your excellent work.

Do I have to do a movie of the RIG + kill a watt for you to trust me ?

I don't have fury's or nano's to play with but after what I have seen with hawaii and latest claymore I don't need to see any videos...

lol yeah i dont buy it 125 watt from a fury ? gimme a break lol

My basement is a little messy and the rig case is home made wooden "ghetto style" rig
But the proof that you can do great things with R9 Fury with only 125W per card.

PS : I shutdown the old rig with the 7970, so the kill-a-watt is only for the Fury RIG

Trade that wood for aluminum and never look back. I can't stand people using "fuel" for heat containment.

I just came across my old 7950 in storage. What numbers are people seeing on 2-3 GB Vapor-X 7950? Worth running?

[th00ber]

Yep, 7950 can do something like 110-120 H/s I guess

i'm looking to add another another card to my measly one r9 280.  is there much difference in sols between a 470 8gb & 480 8gb card?

RX470 ~160 H/s
RX480 ~175 H/s

Claymore v7, intensity setting (-i) 4

Not too much difference yet. 470 is cheaper and more efficient than 480.

RX470-4GB --> 171H/s
draw 210W from the wall.
single gpu with intel core i3.
im sure if i put 5 gpus it will reduced a bit.

470 is more efficient at this time.

What is the hash rate on SAPPHIRE NITRO Radeon R9 Fury ? should I go with 470 or NITRO Radeon R9 Fury

Radeon R9 Fury soon will be on sale http://www.newegg.com/Product/Product.aspx?Item=N82E16814202186&ignorebbr=1

I have that card.  The stock hash rate is 238 - 240, 225 @ 155w at the wall if you undervolt -100 and power limit -45%

I have also the 470 4GB Nitro, and it does 155~ Hashes.
I would kindly ask you if you could you post your .rom here please using ati flash.
Would be amazing!

Sorry, I was referring to the fury. Don't have a 470

When be new miner?

[delle54]

As Claymore said, in 2-3 days. Don't await miracles.

Again: dual mining is not possible for ZEC because it uses both GPU cores and memory intensively.

[heavyinbitcoin12]

Yep, 7950 can do something like 110-120 H/s I guess

Actually the 7950/280x is by far the best card for zcash. They cost $80 and can do 180 h/s easily constantly.

This is without mods. 110=120hash was like version 5 man. Need download version 7 for 180hash

I get about 85 - 90 on mine.  Overclocked to 1125 / 1500 power -15 in Afterburner.  One runs at about 80C and the other around 70C (I have it set as -tt 80 - tili 85 -tstop 90) and the fan runs about 60% (I want to improve my cooling, but it is very stable right now).

So, it sounds like you are in the ballpark with 87 per card.

This is true with modded bios.
7950 165 sols
280x 180 sols
rig with 1 7950 & 2 280x 510-520sol/s @ 610-620watts from the wall. system idle 175-190watts.

Yep, it's true: 175-180 h/s. And no mods, only overclocking (1180/1500 for me).
BUT, there is a downfall:
ETH mining, v 7.3 - 845W from the wall on 4x280x
ZEC mining, v 7.0 - 915W!!!

I'm new to all the mining things, but how can you trust someone, who uses closed code, meaning, that noone knows whether or not the moment you run it on your PC it does not start sending all your data to foreign sources. Starting with your location, ip, IP camera, etc, and in the same time is asking for a percentage of your earingings in order to cover the abovementioned?

Well you can never know for sure, but there is such as thing as packet capture programs you can use to monitor the traffic being sent in/out of your machine in detail. Wireshark is a good place to start if you are actually interested in learning. https://www.wireshark.org/#download

[spyder09]

Got my rig running again on v7 I swapped riser and installed drivers again for my older cards and bingo running stable right now. All stock unmodded (that I know of) 2 r9 280x at 168 each and 2 r9 380 at 118 each for total about 570h/s
Not sure on power usage I don't have a watt meter

mod your bios. can probably reduce power consumption.

What happens if the code is linked or transmitted within the crypto transactions we are all making?

1) What (TH) do you mean with "the code" and "crypto transactions"? The communication with the wallet/pool? What should, for example, flypool do with this sent extra information? Do you have any idea how mining works?
2) Everybody should and can have control over any traffic inside and leaving his network if he wants. But many just don't care (enough)...
3) Start with using packet capture like Za1n suggested.

[GH]

I meant from me to pool.
But does it mean, that the miner program cannot get our IPs? And transmit them by ETH project?

Every target server you connect to (for any purpose, not only the "mining program") knows your public IP address. That's how the Internet works. But let's stop this here, it's getting off-topic.
