Ethereum GPU mining?

[poofyhairguy]

So my 4GB Asus 460 mines at 11.76 out of the box if anyone cares. Isn't as low I expected, gonna see if over clocking VRAM helps any.

Getting strange results on 1 rig... worked ok with 4x 480s over the weekend, the rig crashed sometime in the morning, and now can only run 3x 480s. As soon as I add a 4th card Windows won't boot properly and goes into the troubleshooting screen on start up.

Power supply problem?

Anybody have the latest average ETH mining performance numbers of the 1080 & Titan cards?

Ive seen reports of Titan XP doing 30MH stock and up to 34MH with +400 mhz on the VRAM

Seems like I have a problem with setting 3 card mining rig.
I have asus M5a97 R2 mobo and tried running 2x480 from pciex16 slots and r9 290 from pcie x1 using x1 to x16 powered riser.

There was only one of the two x1 slots available, because slot #1 was covered with rx 480 in the upper x16 slot:

Sadly, it didn't see the card in pci x1 #2.
Tested risers and they work when plugged to PCIex16

I couldn't find a single setting for PCIe in the bios.
Any ideas how to make it work?

Everything is in a PC case, so it is damn hard to manipulate. I think milk-crate is inevitable...

So I plugged all 3 cards using risers and it works.
PCIex16_1 PCIex1_1 and PCIex1_2 are occupied by rx480 x2 and r9 290.
It is working almost 24h straight hashing 83mh/s. No burned PCIe slots yet

Now I'm contemplating getting another 290 to boost me above 110Mhs. Or just could wait for Vega.

Interesting. Is that the 4 Gb Strix card? That's not bad for $145, though you can get about the same from a 4 Gb 370. I would expect that the 370 would use more power though.

Might be a PSU problem but I'm having a somewhat-similar problem on my rig where my new CPU (same mobo, same RAM, etc) won't boot with the 3 cards I had in the rig, only two. In my case it might be a problem with the on-die PCI-e controller.

Yeah it's the 4GB Strix, I got it for $121 thanks to Jet.com. It doesn't do as well as my 2GB 370 currently that averages around 13, but the 370 uses much more power and will be dead in the water come December when 2GB cards stop mining.

Speaking of which I need to dump this 370 before then I guess to avoid the landslide.

 

[DrMrLordX]

Not a bad price, less than what you'd pay for a 370 a few months ago. How much power is the 460 pulling @ stock when mining?

I will get back to you on that once I tune the best rates in. For example a VRAM overclock got me over 12.

Anyone know if we'll be able to cash out normally once the ethereum process switches to proof of stake (POS)? I have a 470 and 480 mining at 48Mh/s and was going to move them over to a work computer, but after just finding out mining as a little guy will be no more once it switches to POS, I'm wondering if I should sell/return these cards or just mine all the way until it switches to POS and then cash out.

Thanks, was curious . Ok, but still not economically viable I guess.

I swapped out another power supply as well as motherboard/CPU/, still no go on the 4th card, very strange! DDU'd the drivers and safe mode is stable with 4 cards plugged in, but can't install AMD drivers without it crashing. Appears to crash the when the screen goes black after 'detecting' the cards/monitors.

Trying different riser as a last resort.. then will reinstall Win 10 but pretty sure I already did that!

EDIT: With 4 cards plugged in, after a completely fresh Win 10 installation, still cold reboots when installing "AMD Display Driver". Strange af... have a few rigs and this is the first one with these issues.

Pretty sure you can still cash out after it changes to POS!
If not strapped for $, why not keep mining for a bit longer and see where it goes? Since you're already all set up anyway, I don't see a need to pull out at this moment, IMHO. (unless heat/noise is bothering you)

Good to hear you got it going!

In that case I'd suspect one or more of your cards. Do you have a 5th card you can swap in to test?

To be honest I expect ETH prices to jump after PoS is announced. People will need to hold fairly large quantities of ETH to earn anything significant in PoS, so it'll put purchasing pressure on the market. There will probably be staking pools to spread out the risk and get people consistent earnings.

So yeah people will be clamoring to buy up ETH to build their warchest, so to speak.

I do - I have cards 4, 5 and 6 ready to go but all sitting idle

I tried card #5 previously (it was a low ASIC card in the 60s) and didn't have much joy either. I'll try again...

Edit: managed to get card #6 going so now I have 4 out of 6 cards working. Card #5 not recognised when plugged in. Maybe I can find some spare parts to make another rig to test the 2 remaining cards. Very strange this one...

 

[DrMrLordX]

Yeah pretty weird. Or are they within their return window? You can just send them back.

so jumped into this with an open box 480 and getting 22.5 rather consistently, which seems low compared to what yall are getting. any tips? i've got the voltage in wattman down to 1015 for state 7 at 1266. i haven't done anything to the ram or power limit. fan adjusted the target to 3500 rpm, target temp to 60 and max temp to 80 as suggested.

using latest genoil official (ethminer-0.9.41-genoil-1.0.8)

22.5 does seem a bit low. 1266 for state 7 is too high;

Also, have you tried Claymore's Miner? - https://bitcointalk.org/index.php?topic=1433925.0

Scroll back a page or two for MadPacket's guide, but in general I've been aiming for:

- core ~ 1000Mhz @875 - 900mv
- memory ~ 2200Mhz @900mv

If you are going to use Genoil's ethminer, I recommend going with the 110 branch. You can get DAG generation directly in card memory (same feature as in Claymore) which is nice.

 

[ElFenix]

OK will do more testing tonight

 

[Raduque]

Did some reading on PoS and decided I'm going to just run my card till mining's done and cash out. My 280xs (I'm buying another one) will go back to being used for gaming. I might CF them, never done that before.

 

[reb0rn]

Don`t listen to FUD by some holders, as soon ETH switch to POS it gona die slow death, POS is not secure not decentralized
miners will have no interest to keep but to dump, big holders, Vitalik and his band of thiefs will stake (small ppl can not stake and risk coins) POS and make more ETH from nothing (POS is inflation in control of one dictator you know who?)

Anyway to stay on topic, 1070 can do 33Mhs if it has a samsung memory at clock of 2350mhz, GPU ~1400Mhz, power usage ~90W

 

[IEC]

Yawn. If I had a $1 for every time someone predicted the death of Bitcoin (and now ETH) I'd be a millionaire.

Guess what? Blockchain technologies are here to stay. Even HHS and the ONC see its potential:

So, core of this thing is an undervolted champ, running just peachy at 1000 MHz @ 0.8 V. ram, not so much. Hard crashed at 2180 MHz@ 1 V, artifacting at 2150 MHz @ 0.965 V.

Per GPU-Z this chip is garbage, bring better than only 7% of samples. Maybe that translates to terrible overclocking but the opposite when you underclock.

I'm looking to separate my mined Ether between different locations, so I need a new ether address.

Do I want to create a new "Account" or a new "Wallet Contract"? I'm just as confused about this as ever (even asked about this before)
