Ethereum GPU mining?

[thilanliyan]

Yeah I think a 1070 may be on the cards for me...hopefully Win10 mining on those cards gets sorted.

Grabbed 3x from Microcenter today, I'll let you guys know how well they do in our rig. Blower fans help us since we're case limited right now and the noise doesn't matter.

Unfortunately I won't have power measurements for you guys since we don't really measure/care about power use. I'll test with the newest drivers as well as with the old 15.x series that Claymore recommends.

Awesome thank you.

Looking forward to your results. I agree blower fans are best for mining regardless of the noise pollution.

Yeah unless the prices (at least here in CAD) drop another $30 - $50 for these Polaris cards I may consider replacing my 390 with a 1070. Nvidia just needs working Windows drivers. The 1070 looks to be much more power efficient for both mining but especially gaming. The Fury Nano is another option but prices are still above 1070 and performance isn't that much better than a 390. Too bad I have a FreeSync monitor! Can't win.

I don't see any mention of this on https://blog.ethereum.org/ ?

It's all over Reddit. Gavin Wood already posted the code necessary for the hard fork.

Have 2x RX480 4GB cards on the way.

At $199/ea they should make decent bang for the buck mining cards.

Post your results when you get them mining!

With a hard-fork the Ethereum network looses all of its promises. Because
according to "the steadfast iron will of immutable code." the hacker is the rightful owner of the coins. Now of course they found there is a mismatch of the iron will of the code and the will of a few persons, which are now pushing the hard-fork.
How can anyone ever rely again on the code-as-contract concept, when it is possible to invalidate the contract later?

Please take your Bitcoin ideologies and incorrect assumptions of how Ethereum should work elsewhere. Both you and reb0rn are contributing nothing to this thread. There's plenty of trolls on Reddit, we don't need more here.

Will you be able to post power consumption measurements as well? Would be nice to see the bigger picture of where it stands vs Hawaii.

I am especially curious to how it compares to an 800 MHz undervolted R9 290.

edit: Or you MrTeal

 

[MrTeal]

I just bought one for S&G to play around with. At CDN$309 I can't see it comparing well to my pile of $229 refurb 290s, but I want to tinker with it and see how it does.

Are the 4GB actually in stock anywhere? I didn't think they were launching today.

Do you mind sharing where you bought your card from? Cheapest I've seen in CAD is $339?

Really NE and NCIX are the only places I usually order from, but I prefer NE since they let me pay with BTC.

Edit: Newegg.ca doesn't have their links together yet. I had to look up the newegg item numbers on the US website and then copy and paste them to the Canadian one.

Newegg had 4GB cards, very briefly:

Max qty per user was 2 per SKU, to fend off the miners I suppose. I can do power measurements when they get here, but they will be system power measurements, not isolated to the cards themselves.

 

[Erenhardt]

Not sure if it was posted;
Testing the AMD Radeon RX 480 for Ethereum Mining
scsc


28MH/s with memory OC to 9000 which is a overclocking software limit. Who knows how fast it is with over 9000.

Core clock can be lowered and voltage decreased without impacting hashrate.

We need someone to test different driver versions.

 

[Erenhardt]

Just search it in google

The forum is giving me pain...

 

[Mercennarius]

Anyone know when Amazon will put these on sale in the US?

Thanks!

I was checking NewEgg.ca this morning and was confused to not find anything listed. I had over $100 worth of GC to spend at NewEgg so I caved and just bought the same Sapphire card

I need something lower power, comparable in performance to my 390 but with freesync

I was going to wait for 1070 but the lack of freesync and +$200 more before taxes made me rethink it. The 4GB model will be ideal for mining / 1080P HTPC gaming but this card will be for my main 1440P gaming PC / mining during downtime so the extra GB's don't hurt. Although $60 CAD extra for the 8GB model kind of stings.

I will do power measurements as well, no worries.

 

[IEC]

Seems the 4GB cards are inexplicably clocked at 7GHz on memory vs 8GHz on the 8GB cards. So I'll have to check how far they OC on the memory.

If it still OCs to 9GHz on memory not a big deal. If it craps out at 8GHz or below then it may not be worth the small discount as it reduces your hash density.

 

[ZGR]

It looks like a great upgrade from a 290/390 for mining. I wonder what the memory OC limit is. The power consumption increase is well worth the performance gain.

 

[poofyhairguy]

So the refurb 290 is back on Newegg:

http://www.newegg.com/Product/Produ...02218&cm_re=amd_r9_290-_-14-202-218-_-Product

I am having a very hard time deciding between it and a new 480.

No comparison...the 480 is a significantly better buy for $10 more than a refurbished 290 you get much lower power consumption and better performance. Not to mention the updated HDMI/DP standards.

Or maybe mining won't be so good on the 4GB? Why would they limit the memory speed of the 4GB model, seems artificially done but could be for binning, I guess we'll find out soon enough. Good luck with your cards!

Keep in mind the 4GB will use different, lower density GDDR5 chips. There's obviously 8Gbps chips available in that density since nVidia's used them in the past, but it very well could be that the 4GB will reach different OC limits than the 8GB chips.

I am looking at the $240-$250 480s because Newegg doesn't have 4GB models in stock. Leaning towards XFX $250 one with a backplate, but is it worth $60 more than refurb 290?
