But seems that this DAG has affected all GPUs right?
It affects RX4xx/5xx but not older AMD or NVIDIA cards. Also the RX580 8GB versions? Yup, it gets to all of them. Maybe not only the newest versions

Is this affecting EXP and ETC with the same rate of impact?
Hmm... Looks like this issue indeed affects ETC, too EXP was not affected by this problem. The DAG is only at 22 on that fork. My rig mined at the expected 29.7MH/s, rather than 27.5MH/s.

why the f is that the case that only RX series cards are affected, this is crap i tell u Yeah. The ice age is for the entire ethereum mining community. I too dont understand all this crap against AMD's RX series. More likely, it will depend on the memory of cards, 4GB cards will soon be too low to handle DAG. So the hashrate will not drop on Nvidia cards? I'm going to build my second rig and I'm not sure if I should move from AMD RX cards to Nvidia, maybe I will open a thread too. If the hashrate won't drop in Nvidia cards then I would purchase nvidia cards before the AMD ones.

If the hashrate won't drop in Nvidia cards then I would purchase nvidia cards before the AMD ones. The Nvidia 10 series cards are not affected by the epoch increase. So far I have been able to offset most of the ETH hash drop on my mixed five card RX 4XX/5XX 4GB and 8GB rig from every new epoch by lowering the DCR dual mining intensity from -dcri 25 to -dcri 21 and the dual mining speed has taken a big hit.

Has Mr Claymore himself comment on this issue?
With every epoch the world is seeing performance drop on the RX series. Is it actually a software problem unable to correctly access the larger memory chunks or simply an AMD architectural limit? Will there be a solution or will there not?

Probably the design is flawed, supposed there are 2 memory banks, 1 is 0 to 2gb and the second is from 2gb to 4gb, as soon as the eth miner accessed anything after the 2gb there are a decrease of performance, cache or likely constraints while accessing over and over it, but then again you would say okay but what about the 8gb polaris, see that is the thing, if there are 2 memory banks then the 8gb polaris should not have any performance degradation, so it might be another thing, cache or a series of flaws regarding how it access the memory. Dont think Claymore will be able to, amd need to update drivers and that is it, its up to amd, now i wonder if amd will really do it cause they want their vega line to sell and miners to buy it, so forget it. AMD will leave all polaris owners in the dark hehe

I must be missing something or too tired, but it makes no sense. Why the heck OpenCL implementation will become so dramatically less efficient after certain DAG on just some cards if memory is not an issue?

With the 30% hashrate drop, 40% price crash and plus 300% difficulty, for you to have the profitability and return of investment in mind then you have to think of only going long with eth or any other alt. Selling as you mine now would mean gameover. You must hold and be patient.

Yes . Soon maybe gameOver - up to 1-2 month max now price for card rx 580 8 gb is 400-500 eur - used - no have new at moment many people is crazy and buy on this price and after 1 month they sell on max 150 eur same cards

With the current profitability, gpu's will start pilling up on computer stores hehe, mining is already not worth for many people in many countries cause the electricity cost takes most of the profit.

Pretty sure most people pay $0.10/kwh and for mining to be break even they would need to make less than $0.36/day. Which is a long ways away.

Check the electricity per killowatt cost in european countries, http://ec.europa.eu/eurostat/statistics-explained/index.php/Electricity_price_statistics, its average is $0.20/kwh, worldwide is around that or more expensive. For example, a 1080 ti using 190 watts per hour pulls around 5 kilowatt per day, that is $1.00 per day, it makes around $3.08 per day on zcash, taking whattomine reference, with a 1080 ti you are earning only $2.17, in most countries that card is sold for $1000 or more but lets take a $800, now 800 divided by 2.17 which is today, not counting difficulty rise or anything, that is just now, that means 368 days, which means that is a blood year.
