Tundub jah et on vähemalt RX480 8GB on hakanud DAG epohhi vahetudes kiirust nüüd kaotama:

00:00:24:602 180 ETH - Total Speed: 169.535 Mh/s, Total Shares: 28955, Rejected: 7, Time: 193:39
00:00:24:774 70c Setting DAG epoch #130...
00:00:49:997 180 ETH - Total Speed: 168.918 Mh/s, Total Shares: 28955, Rejected: 7, Time: 193:39

4GB RX480 kaartidega sama lugu:
00:00:37:486 c04 ETH - Total Speed: 168.524 Mh/s, Total Shares: 39663, Rejected: 11, Time: 269:52
00:00:37:736 1360 Setting DAG epoch #130...
00:01:02:926 c04 ETH - Total Speed: 167.771 Mh/s, Total Shares: 39664, Rejected: 11, Time: 269:52

R9 290X kaartidega aga midagi ei muutunud:
00:00:45:055 11e8 ETH - Total Speed: 141.324 Mh/s, Total Shares: 49486, Rejected: 13, Time: 397:00
00:00:45:258 11c8 Setting DAG epoch #130...
00:01:10:816 11e8 ETH - Total Speed: 141.242 Mh/s, Total Shares: 49486, Rejected: 13, Time: 397:01

R9 290 seeria läheb veel eriti hinda nüüd.

Currently, an epoch takes about 4 to 5 days to conclude until a new one is started. That means that in around five month's time, a user with an RX 470 4GB will see an almost 30% decrease in hash-rate, with the same power consumption of today. And as you know, in mining, power/performance ratio is all that counts for profitability. It is expected that NVIDIA cards being used currently, such as the GTX 1060 3 GB, will see decreases as well. And there are other performance-affecting details that originate from the increased worker size as well, such as TLB (Translation Lookaside Buffer) trashing, which could see performance degradation even before the memory pool of your graphics card of choice is fully loaded, provided the TLB is itself being overflowed... With Polaris, AMD implemented a TLB cache which was, before, absent from the GCN architecture. The small size of this TLB cache means that Polaris graphics cards will likely see performance penalties from TLB trashing before the DAG size increases to their memory limits. Just another point for you to consider.

Now granted, if you know anything about Ethereum, you probably won't even care about this: the passage from PoW to PoS (Proof of Stake) is expected to occur by November 1st of this year. This means that ETH mining will simply cease to be a thing (though this implementation could see some delays, unlikely as that is.) And it lines up nicely with the 5 month, 30% computing power decrease estimation above. So maybe you don't have to worry that much about ETH mining ceasing to be profitable in 5 month's time. But if you are looking to buy into the mining craze and invest in hardware, you should study this market, and this technology, first (and pay attention to this article as well.) Likewise, if you have just recently bought into the mining hardware market with those exorbitantly-priced RX 400 and RX 500 - do the math and be ready to look for alternatives, either in cryptocurrencies or mining solutions. Don't let yourself be burned just because you want to follow the train.

Miks see R9 290 seeria hinda läheb? Ma ei ole selle kaevandamisega üldse kursis ega tegelenud, seega puhtalt uudishimust ajendatud küsimus.

[Slaava007]

Kellelgi eruptereid või mingeid USB minereid ala Butterfly Labs jne on pakkuda?

Oh jah, ma pean seda juttu nüüd uuesti siia kirjutama hakkama. Inimesed, miks te ise lugeda ei viitsi?

280x 100 eur eest siis varsti on ka parem kui rx580 400 eest?

[yerba]

Eiole

No jah, vaatasin - neil on erinev m2lu (bus, gb) v6rreldes 290-ga. M6tlesin, et 280 on 290X praak.

Igal juhul m6tlen, et muua oma r9 290 ja osta 1060 oli rumal idee. Tundub, et varsti teenib see nagu x2 gtx1060 ja maksab 3 korda v2hem

Ohoo, saab tellima hakata otsast

[elukaz]

Läheb sots võistluseks kes rohkem kaarte käima saab

[dohc-48v12]

näha jah et hetkel ainult 8 kaarti järel Ülejäänud kuus slot-i vaba.

Aga paistab et 1080ti suudab ETH-s teha 39Mh/s ka ~265w-ga

[Wusses]

Tasub hetkel kaevandamine ära?

Vaatasin mingit bitcoini kalkulaatorit ja sain et 1x 280x teenib umbes 0,04s kuus.


Või olen ma väga valesti aru saanud kaevandamisest

[mikk55]

Mida siinsed kaevurid äikese korral teevad? Puhkepaus või usaldus Seasonic toidete või Corsair AX seeria jne vastu .

Mina laen serveriruumi upsi niimoodi suvel tasuta elektriga täis.

[Catfish]

Pole tükk aega kaevamisega tegelenud.
Praegu jalg lõhki, mõtlesin et kiusaks igavusest veidi vanu kaarte (270x, 280x)
Annab nendega üldse midagi kaevata tänapäeval??

Proovisin XMR-i: 6-tuumaline prose annab igatahes rohkem välja kui kaardid

On kellelgi häid ideid

[dohc-48v12]

eth/Zcash/etc. Kindlasti on veel mida kokku kühveldada. Otsinkusse gpu mining.

[elukaz]

280x kühveldab exp-i umbes sama hästi kui 470, tasuvus on sarnane ethiga. Aint voolu võtab poole rohkem.
Kui aja ülejääk on siis võid mälu taimingute biosmodi harjutada, 270x annab sedasi 20Mh välja. Parim bang for buck.

Mõtlesin ka et harin ja proovin kodus kaevadamist. Puhkus ja midagi targemat pole teha


Sain veidi imelikud numbrid 270x kohta, eriti see esimene
