Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[citronick]

I'm surprised that no one is taking pre-orders for them yet.

Same here.  I'm kind of in a "Catch 22" situation.  I was about to purchase 100 x MSI 390 GPU's until I heard last night about the AMD RX 480 with 14nm chips coming out June 29th.

Especially, since no one is taking pre-orders on them, I'm wondering if there will be limited quantities that will limit retailers to 5 GPU's per customer at first?

meh I think 390's are a good deal when its a good sale price, even with the 480 coming out.  Depends on your electric setup.  I'm waiting for 480 too, but if I can get some cheap 390s...I'll get those too   although im not buying 100 god damn lol, so far my XFX 390s are running over 33mhs, good temps, and seems perfectly fine.

100 x Nanos would be a better bet, IMHO.
Lower power consumption delivering as good MHs @30MHs per GPU.
Also resale value is better than 390.
390 is power hungry and produces lots of heat - require 2 VGA cables, Nanos require only 1
390 is a bulky, long, heavy card.
Nanos smaller and lighter and easier to manage in an open cage.
Savings: Lower electricity bill and 1000w / 1300w PSUs instead of more expensive 1600w or 2 x PSUs.

My current rigs,
Phase 1: n x 5 x MSI-R9-390, 150MHs, AF settings: -100mV/1050/1125, temps =75c, 1300watts (6xGPU will require 1600 PSU)
Phase 2: n x 6 x Sapphire Nanos, 178MHs, Heliox Rom Mod -150mV,1040/300, temps 74c, 1300watts
Phase 3: Work in progress: Nanos for now attempting -175mV and -200mV Rom mods. If 480s passes the ETH mining test on CDM, that will be the card to go for : latest GPU & lower power consumption

Wait, I'm not 100% sure on this, but is the 480 the top of the line, or is it only the next-gen 380, and then there will be a "490", etc?

I was thinking they were advertising the RX480 as the "sweet spot" for price/performance and stuff, but I didn't think it was their highest-spec GPU?

Knowing all this, would it be worth getting a 290 right now? People want an arm and a leg for 390's it seems, but even the 290 is expensive at well over $200 for aftermarket versions. But then, the RX480 would outperform it for $200 anyway... I think. Guess we'll have to wait until the end of the month for a clearer picture. :/

Apparently dmwardjr is some kind of bitcoin prince lol. Mind throwing a few my way? Not even sure I can pay my rent this month. XD

No, but seriously.  

Yes, it appears we may have to wait.  Not sure.  Wish we knew something concrete NOW.  

No, not a BTC prince.  I've had as much as 148 TH/s (30 x S7's of varying batches) mining out of my home.  I have not sold any BTC I've mined to pay for power costs ever since I started mining.  I paid all of my power bills out of pocket ever since August 2014 to hold on to my BTC to sell for bigger profits at a later date.

Sorry, cannot pay your rent.  My wife was laid off from her job (Accountant for an oil and gas company) the second week of January this year.  We are now relying on me to provide for us by whatever legal means available.  Hell, our health/dental insurance for the three of us (I have a 5 year old son too) is $1,530 monthly.  That's a damn house note by itself but I have one of those too.

Eh... Was worth a try.  

Well then... Here's to us all being BTC princes, when the price goes up to $1,000,000/BTC.

Any thoughts on investing into S9's? Only thing that sucks right now is the block halving... I had a decent enough hashrate to get to where I want to be at around 10 BTC. Looks like it'll take a while longer now... Even if the price goes up, I'm just bag holding and didn't care about short-term anyway, so it's still a big disadvantage from that perspective, rather than just cashing out if the price goes up right now...

[citronick]

Not sure if this question has been asked yet or not:

Will we have to wait for someone to write a special software for the AMD RX 480 4GB coming out June 29 @ $199 USD in order to mine with it?

Hi Dave, See if this answers your question..... http://cryptomining-blog.com/tag/radeon-rx-480-eth/.

It will mine with CDM no doubt.

The question is how many MHs, since its memory bandwidth is half of a Nano although the same capacity of 4GB, and we all know ETH's algorithm Dagger-Hashimoto is very memory intensive.

Will be watching the 480 and 490 space very closely. At 199$ its a perfect miner: low cost, low power..... we shall see

Does anyone know of a Linux CPU miner? I would like to mine at nicehash.

By the time you get the new card, you will mine the same amount with the same price as the difficulty will be much higher.

You have a valid point there.  By the time they come out and a ginny pig spends $200 to find out if it will mine ETH and we get word of it, it's quite possible my 3,000 MH/s from 100 x MSI 390's will have mined approximately $10,000 worth of ETH at current difficulty, block time and price of ETH.

That's $10,000 towards a $34,000 to $35,000 investment.  That investment could be paid off in 4 months.

I'm an ignoramus as to how ETH works.  Any idea who or what determines when ETH changes from POW to POS?  Of course, I could research to find out for myself.  However, if someone knows the answer, I would appreciate the info.

I was researching this topic earlier this year and find this link best to explain POS/Casper and Life after POW.

Hey guys,

I'm about to buy a 295x2 but still have some questions.

It's a Sapphire one.


What speed should it get with claymores miner on ETH only Windows 7? Do you think 60 MH/s is realistic?

What core clock, mem clock, voltage should I run it?

Anyone got a rough estimation of the power consumption for ETH only? My rough estimations tells me ~ 350 Watts under full load.

Is the stock hybrid cooler strong enough to hold the card below 75 degrees celsius?

WHATEVER you do, don't use Sapphire for mining... It seems like everyone and their brother, sister, and mother, are having issues mining with Sapphire cards...

I thought with my R9 270's (2 of them) ~36MH would be my max. I haven't seen it yet.

I'm getting about 25MH/s Ethereum, about 380MH/s on Decred. I can get about 26MH/s in Eth only, but it's worth it to mine decred alongside ethereum. Keep in mind, that's considerably overclocked. Stock on mine is 900-925 Core Clock, 1400 Mem clock. I have it at 1050Mhz Core, 1500mhz Memory.


My two cards together probably use about 350 watts. I would think a 295x2 would use at LEAST 500 watts. Make sure you have a hefty power supply.

As for your expected mining speed... It's hard to really say. Two r9 270's are definitely more powerful than a single 290. So if I'm getting ~26MH/s, I'd imagine you'd get closer to 40. Maybe 45MH/s with a heavy overclock. But again, the problem is that I keep hearing nothing but complaints about Sapphire for mining...

Could you perhaps go with two R9 290's, non-Sapphire?

I don't want to hate on Sapphire. I used to have a passively-cooled HD5450 that I ran pretty hard. I now use it in my HTPC build. I love the thing, even now. But when you hear nothing but problems about a certain manufacturer in this particular usage... I can't help but recommend against it. I remember a thread on the ethereum forum where a guy had like 6 Sapphire cards for mining. Multiple failed within the first couple weeks. Not a good sign...

I run so many cards... and most of them are Sapphire ones. Never had any problems (except one fan that's stuck and doesn't move anymore).

I have:

2 x Sapphire HD 6990 @ 20 MH/s each
2 x Sapphire R9 280X Toxic @ 20 MH/s each
1 x Sapphire R9 270X Toxic @ 15 MH/s
1 x Sapphire HD 6970 @ 10 MH/s
1 x Asus HD 6970 @ 10 MH/s

(all cards above consume together 1380W at the wall including one system)

And now I bought the Sapphire R9 295x2.


One 280X consumes exactly 170 watts.
A 290X might be like 190-200.
That means a 295x2 should be 380 - 400 Watts.

All my cards are currently connected to a Rosewill Hercules 1600W which is doing pretty fine at 1380 at the wall.

I put the 270X on a second PSU (-110 Watts) and add the 295x2 to the Rosewill. Should be fine.


Regarding the performance.
I have seen different stats... 290X's between 26 and 32 MH/s.
Let's say 28 MH/s would mean 56 MH/s on the 295x2 - that's okay.


I gonna run it at like 1050-1060 MHz... but I don't know whats the lowest voltage level it will run.. It's always annoying to figure it out..

So has anyone any experience with the voltage on this card?

Its simple really.

They will release the new software for nodes to update to and if they mine then wont update and POS will be delayed.  The guys at ETH put a difficulty bomb to make mining impossibility hard in the future so the majority will update or the network will freeze and kill the coin.  In crypto generally once 51% of the network decides to use a update then it becomes official, its like share holders making a vote in a publicly traded company.

[merc84]

I have 2 sapphire 280x some of my best cards they run super cool and have never had an issue in over 2 years. I suspect your expecting too much from such low end cards sure they may have done 18Mh/s each some time ago when the dag was smaller but they will continue to drop in performance as dag grows.

[charles2k]

Why GPUs numbering under Claymores Dual are differ from GPU-Z or MSI afterburner?
For example - my rig with six R9 380 cards: - one card has temperature 80C, rest five 68C. In GPU-Z is this hot card on the first place, under MSI Afterburner is GPU1 (numbering starts from 1), but under Claymores Dual SW 4.5 is this card GPU4. Why ??

Sounds like all of us need to begin kick starting our own ETH nodes to have a vote to keep the mining going a bit.  eh?

Hi citronick,

Thanks for the two links you provided in your two posts.  Much appreciated! 

Earlier this year, I invested a handsome sum on my ETH rigs. With this POS thing looming. I did my own study --- I even drop a PM to Vitalik to ask him when is POS date and got no response (LOL... I am so noob)... after talking to several senior members who have rigs and farms themselves in US and Europe, I found the right strategy and exit plan.

[Mimir]

Why GPUs numbering under Claymores Dual are differ from GPU-Z or MSI afterburner?

In known issues:
GPU indexes in temperature control sometimes don't match GPU indexes in mining. Miner has to enumerate GPUs via OpenCL API to execute OpenCL code, and also it has to enumerate GPUs via ADL API to manage temperature/clock.
And order of GPUs in these lists can be different. There is no way to fix GPUs order automatically, thanks to AMD devs.

But you can do it manually. For example, if you have two cards, you can change their order by adding "-di 10". Another example, reverse order for six cards: "-di 543210"

I can't seem to mine on ethermine, can anyone mining on there share their configs with me? thank you!

[BitJunkie223]

I can't seem to mine on ethermine, can anyone mining on there share their configs with me? thank you!

Yeah, absolutely. Here's my config for just ethermine. Nothing "custom", just the proper link, and my wallet address. Just sub in your own address instead of mine, of course.


EthDcrMiner64.exe -epool us1.ethermine.org:4444 -ewal 0x70c06E09AE5A2b8ECa5863C68b725adadCefF5cb -epsw x

-------------------------------------------------------------------------------------------------------------------------------------------------------

I would really recommend mining both Decred and Ethereum. You don't sacrifice any speed for either, really. Here's my entire config for dual mining. Sign up for supernova pool for simplicity because it's already set up that way in my config maybe...

EthDcrMiner64.exe -epool us1.ethermine.org:4444 -ewal 0x70c06E09AE5A2b8ECa5863C68b725adadCefF5cb -epsw x -dpool stratum+tcp://dcr.suprnova.cc:2252 -dwal BitJunkie556.worker1 -dpsw x

Oh... And one thing I found useful. I couldn't get Decred to dual mine at first. I then realized that I had to put in my worker, EXACTLY as it said. That included the capitals on my main account name, as you can hopefully see above. "BitJunkie556.worker1", as opposed to "bitjunkie556.worker1"...

 I hope that helped and that you can get up and running.

[merc84]

@ Claymore curious as to why my 7950's are faster than my r9 280x?

[CoRpO]

@ Claymore curious as to why my 7950's are faster than my r9 280x?

This happens when you don't have 15.12 drivers.
Either upgrade to 15.12 or force the 280x to "slow card" mode (-etha 1)
280x is @ 15 Mhs with pre 15.12 and auto detection instead of 20 Mhs

Doesn't work I can mine fine on dwarfpool and coinotron but not ethermine weirdly =\

[BitJunkie223]

Hmm... That is strange. I'm not sure. I'm not saying to keep it this way of course... But try only putting in my config and not changing it to make sure it'll start mining. Only because I know it's working for me. Although you may have tried that already...

What GPU are you using? Perhaps it's not adequate for Eth mining? I'm on 2 R9 270's.
