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

[Hotmetal]

I also had problems with my 6*480 rig on Ethereum mining. I changed to mine Zcash (using Claymore's Zcash miner) because - as I calculated - at this time it's more profitable to mine ZEC with Polaris cards.

ETH is considerably more profitable (right now) to mine than ZEC.

Depends on the cards that you have : 79x0 / R280(x) go Zcash, RX4x0 go Eth

I should of stated 480's but his comment about his 480's is what I was responding to.

You're right, sorry, didn't see that he was talking about polaris cards ... i'm tired I guess ^^

Will Claymore issue a new miner for the ethereum hard fork tomorrow morning? Or is that even necessary?

It is not necessary. The POW is the same. Ethereum has hard forked many times before. That does not affect the miners.

wow.. now that is a massive farm 90 GH/s

You are right, I mixed it a little.. Older cards are better for ZEC at this moment because Claymore optimizes his miner for those GPU-s. With RX4xx cards you should mine ETH now. But the profitability changes day by day.. so God knows what will be profitable tomorrow.

When I restart remotely and there is no monitor attached to any GPU (6x RX480) Remote Manager and even when I login to RDP miner itself shows onlu temp and fan speed of only one GPU. Is it a known bug or am I doing something wrong ? All other rigs temps are fine and I'm also using tstop command if something goes wrong, but I'm still wondering why is this happening?

if anyone have Asus Dual OC Edition RX 480 4GB.
can he share hashes speed please

Please refer to my threads for more info on the ASUS, although mine is RX480 8GB

Hello

I would like to understand the difference between reported hashrate and current effective hashrate?




What is the difference between these 2 values?

why blue sometimes exceeds green?

And sometimes it is below? I do not understand .

thank you

The reported rate is reported by your rig. Which should be exactly what you see on your software for mining.

Effective hashrate is calculated from the number of submitted shares. More shares = more effective hashrate.
Usually;

Effective hashrate = reported hashrate  * (100%-miner fee%)/100 * Luck of finding share

You have to use an hdmi (or display port) dummy plug (from $10 to $15, you can find some on amazon or ebay) to have monitoring / overclocking working on RX4x0.
IIRC, using RDP disables monitoring too ... better use vnc, jump desktop or team viewer

I noticed it on rigs were are 6xGPUs and windows 10, on win7 6xGPUs everything works great. Also I was thinking about dummies but I'll have to buy 50+ and it costs way too much. If this one GPU output doesn't affect the tstop command and internally miner sees the temps of other GPUs then it's ok, if not I need to find a way

You only need one dummy per rig, not one per card;
It's a consistent behaviour for the rx card, my R9 / 79xx do not behave like this, regardless of the OS

For those who are not dual mining do you get the same hashrate as when you dual mine ? I had that problem before where the hash rate is lower when I'm not dual mining
with my power costs I cant afford to dual mine anymore

Hasn't been worth dual mining for some time (with the AMD RX4xx cards).

I know that one dummy per rig and that's the strange thing, rigs were are 3x RX480 cards don't behave like that, rigs were are 6x RX480 cards randomly do this not all and not every time. Like if I restart rig were no monitor is plugged and it auto starts the miner in remote manager and even after connecting to RDP shows only one card stats, if I restart it second time it will work. For now two out of 13 6x RX480 rigs ar showing only one card stats. Actually I didn't mind it showing me less info, I just want to be secure in case of some card loses it's fan or any other reason overheats it, I just need the command -tstop to work. So the question will be if the miner sees the one card stats only will the command -tstop make other overheated card to stop ?

I am having trouble getting my rx 480 rig to work for anything.  I have tried multiple crimson drivers (I still suspect a driver problem) but I always get the same result.  Claymore's miner crashes as soon as it would normally start hashing, and this is true for both this dual miner and Claymore's ZEC miner.  Ethminer will run, but shows zero hashes (this is true for multiple versions of ethminer).  I have tried removing and reinstalling 5 different crimson driver versions and it all seems to succeed successfully but I am still getting these same results every time.  This PC was running catalyst 15.21 originally with r9 290's and I suspect some artifact from those drivers is sticking around.  Before I proceed with an OS reinstall I wonder if anyone has suggestions.  I have used DDU between crimson driver versions (although not in safe mode just yet).  I am working remotely so can't do DDU in safe mode but I will be going onsite today to try that as my last resort before an OS reinstall.  Anyone have a suggestion? (Win 7 x64 if it matters).
