Ethereum GPU mining?

[Accord99]

Yeah I just tried eVGA precision and I'm still getting the same weird behavior, if I don't have Claymore running, the clock speed of the memory jumps to 6000mhz (or whatever I set it to) if I apply the overclock in the software, but as soon as I fire up Claymore and start mining, the clockspeed drops to 5500mhz or so @ +1000mhz. If I set it to +900 then its 5400mhz and so on. I feel like I should be able to get more performance out of the card though, 25MH's feels low.

Do you have the newer 1080 with the faster 11 Gbps memory? Because I've never been able to get close to 6000 with my 1080 purchased last September.

But that kind of Eth performance for the 1080 is pretty typical, it's badly hampered by the higher latency GDDR5X memory. You're much better off mining other coins and trading them for Ethereum.

No, I've just got a pretty standard GTX 1080 windforce. I did read this on the claymore thread so it seems to be a common issue. I doubt I would get much higher than 5500mhz anyway, but 5600 or 5700 might be possible.

I started mining with Claymore a few days ago and I am seeing an upsetting thing.
My GPU is an EVGA GTX 1080 FTW, watercooled, MSI Afterburner reports a RAM frequency of 5000 MHz, which is fine... but when mining with Claymore, the RAM frequency automatically drops to 4500 MHz. If I stop mining and start a game, the frequency goes back to 5000 - the 4500 MHz behavior only appears when mining using Claymore.

I suspect the driver somehow knows I am using Claymore and taxes me for that.
If I boost RAM frequency by +1000, it goes up from 4500 to 5500 MHz and the hash speed goes from 20.5 MH to over 25 MH - 25% boost - but this solution is clumsy, because whenever I stop mining I have to dial back the frequency boost, otherwise as soon as the GPU encounters any regular load, it tries to boost from 5000 to 6000 MHz and the memory can't handle it.

What should I do to keep mining with Claymore, but at correct RAM frequencies?

I know the 1080 isn't great for mining, but I don't understand why the 1080 Ti doesn't seem to be hampered by the GDDR5X issues. It's weird seeing people get 27-30MH's with the 1070, 33-37 MH's with the 1080 Ti and 20-25 with the 1080...

I suppose the much wider bus of the 1080 Ti helps mitigate any latency issues.

The 1080TI hashes horribly for ETH all things considered. It does better than the 1080 because it's a lot wider.

1080ti still have the same latency issues
Did you forgot that 1080ti runs on 352bit bus while 1080 on 256 bit? That is 37.5% difference. So 25 with 1080 and 37 with 1080ti sounds exactly what those two cards will get

 

[SimianR]

Yeah, the much wider bus is probably the difference. I'll probably just mine Zcash instead, though it does seem like a pain to have to worry about exchanging it all the time for Ethereum. What's the best mining program these days for mining Zcash on NVIDIA cards? Thanks

Anyway if you know the hashrate of your rig, I can't promise you you'll always get at least $1 per month per MH/s but odds are good that you'll get that or better.

Sorry to reply to myself, but I can see that my old post is going to be buried and I wanted to add an addendum to my numbers.

I fired up Claymore's ETH miner on my 390 in my main rig and while I don't have a valid 6h average on it yet, client-side it's putting out 28.7 MH/s without mining any DCR. But using the bogus average on nanopool, the pool is claiming to pay out $6.36 per MH/s per month. One 390 could put out $182 if the pool average agrees with the reported client figures. I will have better numbers in maybe a few hours once nanopool has a longer history on the card.

At that rate you have a long way to go downward before reaching the old equilibrium point we had about a year ago. There's a lot of room for more hashing power.

So small update on the $229 CAD Gigabyte ITX 1060's I picked up yesterday. Only had time to test one card (had to rebuild my Fury miner which took longer than planned) but it looks promising. Fired up GPU-Z and was somewhat elated to see Samsung memory being used (my 1070 uses Micron). After a few minutes in Afterburner I was able to get 23Mh stable at around 75 - 80% TDP. Memory seems solid at around 900Mhz overclock but looked up at 1000.

Power consumption is absurdly low as well (will have better measurements after adding the remaining cards) so for the price these are a good way to top up any miners that have a few PCIe slots left.

I still recommend the 570's if you can get one at MSRP or less as they end up being roughly the same in performance per watt after heavy undervolting, therefore for every 5 RX 570's you need 6 3GB 1060's limiting you to around around 130Mh per rig compared to 160Mh but the 3GB 1060's are a great alternative.

They even game really well at 1080P so I'll likely replace my 1050 Ti in my HTPC with one of them.

Likely the last mining rig I'm making will be a weird mixture of an unlocked RX 460, a BIOS modded 570, two 3GB 1060's and 1050 Ti). I have an older 850W SeaSonic Bronze that should be plenty to run this frankenminer but I'm hoping to pull no more than 550W for around 90 - 100Mh. Given my dual 64Mh Fury's consume just over 500W this should be a nice performance per watt advantage. I would go with six cards but my motherboard only has 5x PCIe slots.

Madpacket, could you run Claymore in benchmark mode to see if the 1060 3GB runs into the same issue that Polaris will encounter in future Ethereum epochs?

Sure when I get home I'll test this out. These issues don't really bother me as the collectively the difficulty level will drop with these new DAG files likely evening out earnings. It's interesting though.

I noticed a small drop in MHs for my 290X at the same clocks.. It was consistently 30.5 for the last month or so and now it is only hitting ~29.7MHs.

 

[daxzy]

I don't know how the other RX 480's do it, but I'm at 1300/2000 core/mem on a MSI RX 480 4GB and only get about 22.5 MH/s. Which apparently from above, is only on par with a GTX 1060 (makes you wonder why Radeon's are going for so much more).

Also, anyone notice the huge Litecoin price spike? Kinda sad I sold for $33, but oh well.

You have to underclock/undervolt the core on rx480s to get the most out of them (aside from bios mods, which also underclock). Usually it's about 1 GHz on the core and overclock the memory to whatever you can get.

A bios modded 480 will do ~28 mh/s under 100 watts iirc, but must make do with old drivers.

Thoughts? I haven't kept up with any of these ICOs.

 

[MrTeal]

Well, I broke down and ordered a couple 1080Ti's to replace the 390s in my primary rig. Big day, I haven't had an nVidia card in my main computer since before the 5xxx series and mining became a thing. I'll have to look into profitability of different altcoins to see which one is best given the 1080Ti's restrictions as a mining card.

It feels like kickstarter on the ethereum network. So many people blindly investing in things that when closely inspected are no more than well thought cool ideas.

I noticed a small drop in MHs for my 290X at the same clocks.. It was consistently 30.5 for the last month or so and now it is only hitting ~29.7MHs.

I brought all of my ZEC hashing power back to ETH since the ZEC difficulty curve is crazy right now (probably a lot of NV cards mining ZEC right now). First thing I noticed is that all my cards - with one exception - are running HOT on Claymore 9.5 (ETH only, no DCR). Secondly I did notice a loss of hashing power. A 900/1175 290 used to do around 24.5 MH/s, now they're down to 22.3 MH/s. My 390s seem to be doing better - they have more VRAM.

Even with the reduction in clockspeed that was required to tame the heat beast and the loss of hashing power, I'm still making more on ETH than ZEC for the time being. No idea how long that will last.

 

[MrTeal]

Not really Eth mining related, but does anyone know of a shop online that sells GPU waterblocks (preferably EK) and accepts Bitcoin? I'd like to pick up a couple without having to dip into fiat.

Ah, I just checked the US site. Apparently they do sell them on the US facing site. No Canadian shipping though.

Difficulty is skyrocketing for sure but we'll see. 2 months ago one 480 could earn 1 ETH a month. Now my 85MH rate /w 3 cards looks to barely be above 1.2. Was estimating 1.8 a couple days ago.

 

[DrMrLordX]

ZEC difficulty has also risen. It's pretty bad for both coins, though ZEC has gotten worse faster.

ETH is still pretty profitable though. After mining for 24+ hours, nanopool is reporting a slightly-more-modest profit of $5.28 per MH/s per month. Still worth the trouble.

Well I didn't get time to test out the DAG benchmarks tonight sorry. However I managed to put together my Ghetto miner. With the difficulty and DAG issues I simply focused on getting my 3x1060's up and running tonight. Instead of my usual milk crate miner or steel rack I did a ghetto hack job that turned out better than I thought thanks to the ITX size 1060's.

My motherboard and processor are a little power hungry even underclocked etc. FX 8350 + AsRock Fatality 990FX Killer add about 50W more than my new 1700x + Gigabyte X370 K70 when idle. Anyway with that in mind I managed to cram in the 3 Geforce cards and one unlocked Radeon RX 460 into a case. The 460 I ran in the bottom slot as I doesn't have a 6 pin power connector and the 2 of the 3 Geforce cards fit fine. I had one 1XPCIe slot left to suspend the last 1060 all in a fractal design Node S case with ample case fans (still have a Honeywell Tornado fan on the way for good measure). If I get around to it I can pull my 570 out of the single ITX case and add it to this Ghetto box bit it'll take some creativity and re-arranging to get to the 5th PCIe slot.

Right now all cards are mining even if not in the most power efficient platform.

The ghetto box is mining Ether at around 75 - 78Mh and each card sips power. I lucked out and got Samsung RAM with the 3 1060's so they're mining away around 21 to 22Mh at 55 to 65% TDP, 800Mhz memory overclock and -100Mhz on the core. I can make them do 23Mh if I push them but there's no sense as it raises the power 50% or more. If the memory proves stable at 800 I'll try for 900. I'll do some power and benchmark testing tomorrow time permitting but so far so good with these 1060's. I'm pretty sure they'll ROI soon enough. 11.2Mh unlocked 460 in there to speed up the ROI (which I think already mined a full coin itself). Surprised me how easy it is in Windows 10 to mine with mixed AMD and Nvidia cards. Just had to make sure the monitor was plugged into the 460 or the card wasn't tweakable in Wattman.

65Mh - 68Mh for $687 CAD before taxes. Try hitting those speeds with any other Geforce card for the price/performance per watt. Hopefully it passes mining with Claymore 9.5 overnight.

Few pics for the lols.

anyone know anything about Antshares?

Those with Nvidia cards, or otherwise, may want to consider HUSH.

I bought asus dual 1060 3GB two weeks ago after saw that it was on promo price. Went and check and saw it was samsung memory. Ended up buying 3 more from the same store last week. All had samsung. Pretty happy and they all hashes at 22+mh/s at 60%tdp
