use this instead if you have AMD cards

I need to try again, I was getting 0 MH with it cor some reason so swapped back to Ethminer.

now whether or not 2 wire/6 pin pci-e connections (those cheap PSUs we both mentioned) had a blind eye turn towards them because two 18awg wire can safely deliver 75 watts would be a guess. though @Phaedrus2129 has been a product manager for a few PSU rebrands (eVGA and coolermaster) and may answer that.

There is a problem with the 18awg more than 75w argument.

That is only in open air at 25c. Once the wires are bundled/sleeved and in a warm operating environment the rating is MUCH less.

The ATX wiring standard derates everything as if it is operating in a 60c environment with zero airflow while being bundled. This gets you exactly 75w rating on 2x 18awg (number of grounds present).

Thinking about those miners if they want the RX480 they will want the Reference models right. Because the higher clocked AIB models with chance of even further OC will draw much more power that in the end will result is less gain / time mined. Correct ?

One hopes that if there is another mining craze AMD will be better able to plan for it.

The major problem with mining was not lack of supply when potential customers wanted to buy them or even the large used market after the craze, it was that AMD's supply chain didn't expect the drop in mining when it happened so AMD was stuck with a lot of product that they could not sell. Remember all those "inventory write downs"?

Long term, fewer customers with their first GPU being AMD was bad too, but the short term financial pain was getting stuck with too much inventory.

Doubt it. If a card is a good miner, it's a good miner. It might take 2 or 3 more weeks to get ROI but if it's anything like the first mining craze, all models of a card are in demand by miners.

even if it consumes around 200w at 30MH/s they will buy them all
(RX 480)
and if the 470 isnt much slower at 150usd and 5MH/s less it would be even better

The thing is if it consumes 110W and does a set amount of Mining / h then doubling the power consumption for 15% OC seems like a bad idea for wouldn't it make less profit / hour
Double the power consumption of a 6+8 pin AIB version getting +20% seems not so great.

Wouldn't it be better to get more reference cards / rigs rather than less cards but AIB versions not only they will cost extra 10-15% to buy but also will consume a lot more power for just 10-20% better mining ?

At any rate, we should be able to agree that the 75 watt limit is entirely artificial. The spec page for a mini-fit jr is 9 amps per pin, for 324 W on a 3-pair connection. Even if pin 2 were to be omitted, the "six pin" would still be rated for up to 216 W if wire gauge and trace size on either side were appropriate. I feel that the 75W limit was a result of some guy at PCI-SIG saying "surely GPUs won't need more than 150 W total."

sorry you can't get that site to load - it is java bug ridden so no surprise. it took me some time to find it as it seems those (actual) specs are hidden for national security or the like. tongue.gif

however yeah, we are in agreement. hope i didn't come off as an ass, i saw a few details you mentioned that i had hoped to . . . "help you" with. not saying you but i've seen some pretty wild theories about PEG power supply.

cheers and thanks for keeping the discussion civil; too rare around here anymore.

So is Ethereum the new go to Cryptocurrency? How much could a 290X, RX 480 or GTX 970 earn in a day?

Sorry if this is a nooby question, I've been out of the Cryptocurrency game for quite some time and will spent quite some time researching it.
