No, now 430 hash for 1070...

See edits. Still isn't worth it...

Further Edit:

Efficiency Setup - at equal power use for comparison without power costs impacting the analysis.
                    Edit:       Edit:
Card   Price   Hash/s   Power (W)   H/$
1070  $400    380        100            0.95
Fury   $260    300        100            1.15

Full Bore Setup
Card   Price   Hash/s   H/$
1070  $400    430      1.075
Fury   $260    350      1.346

The 1070 has a long way to go before it's worth a look.  The entry cost of $400/card is just too steep to overcome without some serious hash.

it's wrong, the 1070 do 380 at 100watt not 330

If you did a little math yourself you'd see at 380 it's still not wrong.  AMD is still ahead of Nvidia in H/$ running efficiently AND running full bore.  Even with the adjusted numbers the 1070 is still 20% less H/$.  AMD dead?? It's still in the LEAD.

Edit: AMD guys are quibbling over 0.5% using ssl and 2%-4% in pool variance.
Nvidia guys are paying a 20% premium just to play the game and screaming victory.  It would be funny if it wasn't so pathetic.

it is because 380 sol is always better than 300 sol at the same wattage, you need 25% more uselesses components with 300 sol to have the same total hash

you must remember than on large scale the less rig you haev that do the job the better

You are right, Amph. Also, real prices are not listed. AMD Fury is much more than a listed prices. Here is the actual price at the same shop in the EU:


On ebay there is some fury at 260 USD:

http://www.ebay.com/itm/SAPPHIRE-NITRO-Radeon-R9-Fury-100379NTOC-SR-4GB-4096-Bit-HBM-TRI-X-OC-UEFI-Vi-/291648915692?hash=item43e7a148ec:g:A8QAAOSwu1VW7qbd
, also on newegg:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814202186
btw I never bought or tried fury as I know its consume 300W so I prefer to buy 290 or 290x @ 200USD (used). So i wonder if fury consumes 100W


Funny comparisons..

My nano's are close to 325sol while consuming just over 90watt..

Aint that something  Cool

First of all, don't use dos to flash gpu's newer than 290's.

Further, the copper wire trick works fine, used it plenty of times Wink
If that doesn't work, send it back. No other option beyond this.

For those interested in making this themselves.

Google picoip and check youtube as well. Will cost you around 30-40 bucks for the parts Wink

It takes time and skill to write a good stable and efficient miner. I have absolutely no problem with paying someone for their time to do this and release it publicly.

Would you prefer people with these skills to create private miners so only they capitalise? Or perhaps have some steep upfront fee?

If a miner works well, is stable and gives me a consistent hash rate it will automatically be a few % faster than a buggy one that needs to be restarted constantly. If there are tweaks and enhancements to give me a greater hash rate - so much the better. If I share a percentage of these additional gains with the developer as a way of paying for his/her time - I'm more than happy with that.

If the dev fee erodes the improvement and means that it becomes less efficient for me to use than other miners, then clearly I won't use it - that's my choice and something the miner developer should take in to account. All of you have the same choice so I don't understand what all this complaining is about  Smiley

Not complaining, if the miner is significantly faster, ok, fee would be at it's place. If it's not, i honestly don't see the point in using something that is open source and without a fee elsewhere..

Re: RX480 (Reference) 31+Mh, Custom Rom
by

on 17/08/2016, 07:45:53 UTC
Thanks,will try your rom when have little time available.

Problem is:

1.To reduce power-draw need to lower VDDC.
2.To reduce VDDC need to reduce VCCIO(the memory voltage in Wattman,but that is not the memory voltage,that is the memory controller voltage)
3.To reduce VCCIO the memory frequency will drop ,for 2170-2200 i found 5 cards need 0.92  .
4.0.92 VCCIO will limit the VDDC shown in Gpu-z to 0.9187-0.9250 resulting in 75-80 power draw reported in Gpu-z. ( at 1020 core )

This is all on stock rom which i run 1020 core / 2200 memory and resulting in 27 mh/s on all of my 5 cards . Would be curious the gains tighter timings make,can you test in this conditions too ?

Very happy with my results for RX480 however if additional 2-3 Mh/s can be gained in similar power consumption that would be absolutely awesome Cheesy

1. True
2. First time i hear that :p and it's VDDCI Smiley You're right about the memory controller though.
3. Depends.. not every card is the same Wink
4. Interesting, going to test that out..


At this moment, over 1hr rock solid at 31Mh+

Heliox... don't forget W8.1 too. If 120w/32MHs/60c is stable on non-WIN10... this is great news for me. But I dont mind converting some to Ubuntu rigs. Can you share the Linux environment you used for the stable Linux version? Thanks

Haha, just read your post over at Ethereum Forums which is exactly the same :tongue: Made me laugh Smiley

I didn't test on a unix system, got some friends over at ethereumos who did some testing.

But i'll try to keep eveyrone up to date!

Dan rest slechts de vraag...

Wat is een "deftig bod" op alle 5?

Ik heb er echt geen flauw idee van.

Ik zou zeggen, doe een bod als je geïnteresseerd bent. We kunnen er altijd nog over praten dan.

Re: Bitcoin's Price Starting to Go Up....
by

on 12/08/2016, 14:39:02 UTC
You can see now indeed that the value of Bitcoin is rising slowly and that is so nice because you can even now see that the value of Bitcoin was for a long time.
And many people already waited a long time to get some profit so maybe the time will be soon.

When the bitcoin price stays around current level or rises slowly, it is good for me, I can buy more bitcoins.
yeah, it is nice to see the price coming up though it is not an easy thing to see to be honest, the price might be dropping down really easily

Anything is possible with bitcoin but looking at current trend I think it will go higher in coming months as people started to buy again when they saw price drop after bitfinex scam.
We dont know if the price will increase again but its bitcoin the price should be increase so i think the price will hit again back to 600 value its nearly because the price according to coinbase its 593 so i think the price will increase again and it will hit again back to 600 value..

I do not think it will take that long for the bitcoin to reach $900. It will take less than 6 months for the price to be $900.
yeah such price will be reached in like a month or something like that and from then it is going to be going only up, i hope it will make me big profit

That's what everyone thinks. That goes for the big bag holders as well.

So basically, those big bag holders will sell at a certain point too. And guess what's going to happen to the price if that happens?  Roll Eyes

Just noticed these as well

http://ethermine.org/miners/0c93ec1fd7fe2bc1f12413f05296b995c21d6400

Basically the same way.

So combine those 3 and you've got around 23+Ghz..  (of what we can actually see..)

In a way, i'm like: Wtf? That is almost 48-50K USD per month...
Have to admit, best and most intelligent move i've seen in years in the mining scene (if it's him though..). So got to give it to him, congrats for that!

On the other hand, it could as well be a botnet from someone..

Still, there are alternatives, free ones..

Hey guys,

did anyone test the R7 370 ROM and can confirm it? I've got 2 rigs with 12 cards, but at the moment I don't have the time to flash one to confirm it's working.
Tested and it's working, ~15+Mh/s.

[...]I'm always tricked with new message notification here ... but it's not about R9 Nano/Fury Sad
Notification  Tongue

how do you do the flashing?

the same way we did for the nanos?

sorry for noob question.

it isnt everyday we break warranties  Grin

Yup same way Wink

why do people always, want to say or write something... while they have no clue about what they are talking about.

1750 mhz was just an example, i never said that your cards should be using that frequency.

The mod starts with 1600mhz, while giving you ~ 24mh

The mod i gave out for free :-)

Could be.. could also be a botnet.

If it's claymore, you can all see how rich you're making him.

Funny thing is, you can do the exact same thing with open source software..

Have to admit, he isn't an idiot though.. Making people pay for something they can do without his software :p

Duidelijk waarom?  Grin

Gokje: De block-halving (in de praktijk een halvering van de vergoeding per geleverde hoeveelheid hashes), en het uitblijven van een flinke stijging (laat staan een verdubbeling) van de bitcoin koers.

U mijnheer, slaat de nagel op de kop Smiley


Staan nog steeds netjes te koop hoor  Cheesy (even terzijde)

OK, maar waarom zou iemand ze dan voor een "deftig bod" willen overnemen?

Ik zou zelf dan dus meer aan een ultra laag, "lowball" bod denken...  Grin

Althans, gezien het bovensaande lijkt mij dat meer voor de hand liggend...

Omdat ze nog "deftig" zijn :p

Iemand die geen of bitter weinig electriciteitskosten heeft bijvoorbeeld Smiley

Een ultralaag "lowball" bod krijg je weer netjes terug dan hoor ;-)

Maar! Er valt te onderhandelen uiteraard!
