Hi opti,
Why should I take your miner if he
A) more power needed, virtual Ram
B) less hash performance
C) I have to pay a fee 2.5%
D) the GTX 1080TI is not reasonably optimized.
So to point c, I like to pay a fee, but your miner must run significantly faster than the EWBF.
Best regards
EWBF has a miner for Zero parameters? that would be news to me. I think you may be confused with Zcash since Opti does have a miner out for that too.

I'm not an expert so take this with a grain of salt, do oyur own reading and analysis
I remember when RX 480s came out, and they were getting ~19Mh/s on an 8gb card, then people understood the card's specs and now they hash at 29. I don't think there is any single miner that is optimized for Vega yet, so it's using generic kernel. And it all depends on the algorithm and how it uses the card's resources.
The r9 380 4gb can hit like 25mh/s maybe even higher with expert modding and cooling (29 is possible but highly unstable), whereas stock it's like 18.5mh/s and with the case of increasing DAG size for ETH, it shouldn't hit too many snags, since it technically has 384 bit bus, but only 256 accessible(physically), which should indicate that memory access was intended to be optimized for a higher bus speed but Radeon didn't want it being better than the 290/390 price to performance in gaming. In my rough bro-science opinion, it's effectively the same bottleneck on the 470 and to a lesser extent the 480 when the Dag jumps again in the coming months, those cards should see significant performance drops closer to their release date numbers, because they're rocking 256-bit buses and they were made for it.
Vega is a pretty much Fiji meets 14nm, with some improvements. Higher core clock by 60%, faster memory clock by 100%, but half the bus width. I reckon we would have to hit about 50mh/s+ before exhausting the 512 bit memory bus, so unless Vega can hit over 100mh/s (which i doubt) it's going to suffer from poor optimization, and once that's cleared up, it should fetch low 50s at a conservative estimate based on what it's currently doing now to maybe low 70s based on specs, and even higher in pure theoretics regarding how the memory is utilized which might be a hard NO. it should be very resilient to DAG changes, and the gaming cards will be 400-500 USD, 225W, single slot, and according to AMD, even faster, better etc. not a horrible deal. I feel like it should do pretty well in memory hard algorithms where bus or bandwidth are key, like Zcash, Zero(N=192, K=7 ) or Zcoin
You can think of GPU specs as a shipping warehouse, as far as i can tell anyway. Core: how fast the employees are fetching and packing shipping pallets Memory speed: how fast other employees are relaying orders to the core and loading the containers into trucks Memory Bus: how many truck loading docks you have Memory Bandwidth: how fast you are able to load the trucks. Hashrate: how fast you are shipping.

Well, Zcash is the flagship of Zcash/Zerocoin/equihash protocol. Evidently Zclassic took up credible market share because it promised no pre-mine, no founder's reward, etc. but it brought nothing new to the table, it's just Zcash without the baggage. The other one is HUSH (FKA Zdash) which pretty much does the same thing as Zclassic, which i believe is Zen now but not really Anyway, this brings us to Zcoin/XZC which is going through an update, something called MTP, could be interesting. according to wikipedia the difference between Zcash and Zcoin are "Zcash conceals the amount of money sent in each transaction, whereas Zcoin does not. So Zcash is less prone to privacy timing attacks than Zcoin. On the other hand, this comes with a big tradeoff for Zcash, in the form of potentially undetected hyper-inflation in Zerocash’s money supply." I am not sure how MTP will change things as far as mining, but I don't see it being truly effective in the case of stopping a botnet attack, maybe a deterrent only to botnet and some cloud mining. The other alternative in the Z family is "Zero" just "Zero", it's a modified Zcash fork, one better than the original in a mathematical sense, however it is a work in progress and no website or windows wallet exists, and its only profitable for 8gb cards, with some wide margin of variance. Definitely worth looking into, since once, and IF it takes off, it will have Monero and Dash by its sides, and possibly behind it.

they launched recently another algorithm, merkel proof of work, something like that from zcoin team
Do you have any links, resources, something specific, I cant seem to find much? after doing a bit of reading it seems the Zcoin team is introducing a change called MTP (merkle tree proof) but it isn't a new coin. I'll have to sort through the documentation, so it's too early for me to say but, it still seems like its going to stay a botnet/aws magnet, which contradicts the purpose of deterring centralization.

Is it okay to mine and send the coins directly to cryptopia address?? My wallet crashes instantly whenever I am opening it.
It should be fine to mine directly, at least with suprnova, just set the autopayout. are you using the linux wallet? Because I know for the moment there isn't a functional or official (or safe) windows wallet. But I believe one is in the works, it would be an asset to this chain.

Im really interested in what Vega can do. since it will have 16gb of HBM2, and double speed half-precision floating point operations bringing it to ~25Tflops, I always wondered if mining takes advantage of single or half pass... maybe something special can be drawn up? I would say it's a game changer, but at an MSRP of like 1000 USD and very limited supply many likely going into pre-built systems, there just won't be enough to go around.

Just put up version 1.2.0 for Windows which should support NVIDIA! Please test and report back. 1.2.0 is also a bit faster for AMD cards, so everyone is suggested to update!
Note that 1.2.0 uses a bit more memory. Make sure your virtual memory size in Windows is large enough! Page size > number of cards * 8GB!
2x 1070GTX on i5 cpu win10, works but CPU usage is 100% looks like common opencl NV bug speed is 10s/s per 1070 its shame RX have same speed Great to hear that it works! Yes, the 100% CPU usage is a common issue with opencl and NVIDIA driver.. I do not know why NVIDIA has not fixed that. well maybe on purpose as they push CUDA, but ppl say there is solution something about GPU waiting on CPU, but I am not a coder so can`t help, not sure there is common fix but more a hard way to find it and make opencl work on NV with no CPU usage PPS: or time to get used to cuda as AMD HW is out of stock soon we gona have a LOT more on NV hardware + NB mining cards hitting mining space! fu to AMD domination this is true, but when shopping around for cards, nothing brings bang for buck like Radeon. Nvidia got better on ETH and it's king of certain algos and definitely best w/h in a lot of cases but they're usually much more expensive, even from a manufacturer refurb, they're still in very high demand too but, obtainable. I guess it's what sort of mining you plan on hedging. In any case, I have my 390s mining at ~70W 11.1mhs with spikes to the more normal 130W range, one of them doesn't seem to dance much, staying a little higher but it is driving my screen i'm sure if i OCed them a bit and spent a day installing the perfect drivers I could hit +13mh/s each but at the cost of like 140w for 3mh/s. no bad shares either. Even the 390s are going extinct in the wild since they're the next best thing to a 470 at what was usually even under 200$US for a used one. my 480/580s are nice and cool even with ref coolers in summer heat all under 70c with under 50% fans. going to be treating them with the best paste and pads anyway, without going liquid metal. I am noticing my GPU1 in afterburner is showing 16% usage and 100% FSB the others read 100% usage and ~40% FSB, it's also the video-out gpu on this rig. All measurements taken on Gpu-Z/Afterburner, kill-a-watt on its way. so 70W = about ~110W with pcie draw from my understanding. CPU is under 20% (spikes to 28) with some casual browsing, I can even play a couple of games to pass the time with minimal frame penalty so long as i disable that GPU.

mining with GPU RX 470 4GB worth or not ?
It's hard to say, since it depends on difficulty and market price. (price goes up, more miners, less coin per card) 4gb is only about 45-55% what its 8gb variant can do. So I don't want to say No, but, most of the time it's not very worth it. but, considering how new the coin is and how interesting it is, holding on to a few might be a good idea for future highs.

I'm getting these funky messages on my secondary rig. My cards were working fine in my primary rig but I moved them to the other empty one to space it all out Anyway One card starts to mine, the other shows slight temp bump but nothing happens and I get this message:
OpenCL Error: Readbuffer Solutions1 (CL_Invalid_Event_Wait_List)
edit: windows 10 build G1840 H97 anniversary 8GB 1600ddr3 1000w platinum psu
I tried running two separate instances and whichever i start second, regardless which card, will give me the message and fail to mine. Regardless if my main gpu is in the slot proper or on a riser, or which is which. I'm not getting this problem with my other build that i believe only has 16 pcie lanes, although it is a quad.
**EDIT #2**
Had to roll-back entire system, took a few hours to get it running but it works. my guess is it was something that AMD's driver removal missed and so did DDU.
