Lol, the logic of some people on these forums is quite interesting. Please explain how a 2x470 that costs $340 and hashes 1.3GH is so much better than one 1080 that costs $600 and does 1.2GH???

I can buy almost twice the hashpower, or ROI twice as fast with AMD cards than nvidia...but yes those big hash numbers are everything even though it makes no mining sense.

Are you running this off a single phase 230v line? Id love to see this work, but hate to say that running a 300-400 line string would surely end in disaster. There is a reason why most ASIC boards have very short strings, and some multiple strings in parallel. Its hard enough to provide clean power to the asics with a clean 12v DC power input...trying to do that with an a single phase AC line on a 400 line string is insane lol. The ONLY way this would be possible is if you have some very sophisticated startup and hash phase loop control down to each asic (I guess this could be implemented fairly straighfoward by controlling the PLL clock for each chip seperatly, but that would still be a coding nightmare, and not sure what kind of device you would need to have to control 400 I/Os in sync   .

Is there something specific in the ASM that requires modification for linux? Or do you just mean you haven't compiled that linux version yet...if thats the case I can easily compile it myself.

Current hashrate = ~2,000GH
Blocks per day = 288

1/288 * 2,000 = 6.9 GH

You need 7GH currently to get 1 block a day on average. At your hashrate I wouldnt be concerned unless you havent gotten a block after 48 hours.

Solo mining is very sensitive with your network/time setup. Youll lose blocks even if your time is off by a few seconds. Make sure you have very low latency to other node, and you have NTP running.

I've compiled the Linux miner I'll post the repo and binary as soon as I fix some bugs.

Dosent have to do with PSUs...he clearly overloaded his Molex line with 3 or 4 riser cards.

Not at all...your implementation will work just fine under linux, and im pretty sure the majority of miners (at least people with more than 1 or 2 cards) are on linux anyways.

Hmm have you looked at this? https://github.com/olvaffe/gpu-docs/blob/master/amd-open-gpu-docs/AMD_GCN3_Instruction_Set_Architecture.pdf

Its the ASM bible speced out for GCN 1.3. Looking at the GDS spec bit 16 sets GDS, so looks like GDS bit for GCN 1.0/1.1 is 17 with 18-25 for the OPCODE, and GCN 1.2+ GDS is bit 16 with 17-24 for OPCODE.

Yes, optiminer is using ASM on polaris driver under linux, so it works there. His Polaris speedup does NOT work under windows, so it must be a windows restriction.

Why dont you finally reduce your 10% fee down to a reasonable 2%, claim a nice 8% increase in performance AND end up having even more users using your software?

are you trolling or did someone hack your account...I seriously hope its one of those.

A2/Alcheminers have reached break even at 10c/kw with the last diff spike...you can already see the effect...hashrate peaked at about 2.9 TH and dropped about 300GH since then. I bet you will be sticking around the 100-150k diff for a while as we hover around this equilibrium point of A2 going offline and A4/L3 replacing them.

Keep in mind the current gen hardware only increased efficiency x2...hashrate per machine has stayed around the same.

I think I'm just going to post source to decoding app I built...mostly because I think the community will be able to figure out optimal values far quicker than the three of us Im kind of tired of iterating over the hundreds of timing possibilities (and thats just on one algo).

280/x has 384 bit memory bus...380/x has 256.

Unfortunately I dont have the answer you are looking for, but I have been in the litecoin community since the GPU days, and what I do know is that litecoin has consistently been the most stable and profitable coin in all of crypto currencies. Other altcoins and have come and gone, they go through their spikes and dumps, and litecoin has always stayed in the sidelines returning the same profit day in/out.

Like others have mentioned its definitely the long game with litecoin. Yea you can be more profitable putting your money elsewhere right now, but in the long run I have made more gains with litecoin than any other crypto. The second main reason is im constrained by power capacity (have about 10kw dedicated to mining), and currently the L3 cant be matched by any other form of hardware in terms of $mined/watt, be it asic or GPU.

For example and S9 can put out 19 cents of revenue per month per watt, the most profitable GPU algo (zcash currently) 28 cents per watt, and the L3 is now at 34 cents per watt.

So you can see where the true value of scrypt mining lies...for the home miner that is constrained by power (both capacity and price), it cannot be beat. This is the reason I have always been a proponet of scrypt/litecoin for home miners (and is the reason I started my whole scrypt USB stick project...which I hope to continue with a new version on the current generation of scrypt asics). Of course all this comes with a trade off and thats with a higher upfront cost, which again is not for everyone.

So it again it comes down to your individual needs...are you a huge farm with massive capacity and low electricity price? Go with a Bitcoin miner...do you want quick ROI and high resell value go with GPU algos...are you a home miner with high electricity and want to play the long game? Go with L3. But dont make a decision based on a simple ROI calculator and do your research.

So seems like my deal will go through with them, but they wont be able to send out my shipment until the first week of feb. As soon as I have the final numbers per unit and the freight shipping cost from them ill open up another thread for a group buy-in. It will most likely be conducted in a similar fashion to my USB scrypt stick pre order (except you wont have to wait months for these . All BTC will be pooled in a public address that I will send directly to bitmain, they'll pallet drop ship all the units to me in NY, and ill simply slap a shipment label on them and send them out to you guys.

I know some of you guys have PMed me already, but ill start putting a serious list together with the number of units you guys are interested in so if you haven't already shoot me a PM with the number you want (figure around $1600 each unit).

Even at 1100 your crazy...that must be what in the 250 watt territory? I run my Tahiti's at 975 to keep them under 160 watts @ 270s/s. Don't think the extra 10-20S are worth the 50-100 watts per card. 

Yes he has...I told him how to do it
