EWBF's CUDA Zcash miner

[alxyuu]

is there any possibility of adding pool/address switching to the api?

Please check this out

I'm hitting 400 Sol/s / 99W power usage / 40°C / PEC about 4 Sols per W on the MSI 1070 Gaming X

I found out a weird trick, please check out my stupid video and if you have the same GPU, try to do the same as I did on the video to see if that's pure randomness or if that's consistent

https://youtu.be/6IZRgdVr0aI

It's not that weird, It's just changing the core voltage from 1050mv to 744mv resulting in much lower wattage. I did the same thing with Afterburner to my 2 1080ti's.

[Chipychop]

now, testing with 73% power limit, +610 mem and -151 core, an average of 425 sol/s (palit gamerock)
asus strix 74% power limit + 600 mem 30 megahash/s

but I dont know why asus shows 840 mv average and palit 925 mv fixed.... temps

also temps are quite different, 65º asus and 81º palit. I think reason is that the heat produced by asus on slot pci-e nº1 is affecting palit which is on slot pci-e 2


now another test: palit without underclocking core clock and 73% power limit, +610 mem, reduced temperature by 5º degrees..... I don't understand nothing right now and 425 sol/s average

edit again: I have seen that underclocking core clock like I did, in some way affect voltage because now the 2 graphic cards shows 831 mv stable...... incomprehensible

How do you do to reduce core voltage on afterburner ? On my panel I have only the possibility to increase it :-/
Thanks for your feedback

If you're using your cards in a standard case, the upper card will get hotter because heat goes up... but the Palit will naturely be hotter than the strix, it's a much cheaper card with a much less efficient cooler
I would use a gpu riser and use this card on open air
I must say that the msi gaming version has pretty nice cooler, I use to have gigabyte g1 gaming cards, strix cards, and the msi gaming x is  by far one of the best card I've had... really quiet and efficient cooler ... at 80 % you can barely hear it and it gives pretty good temps... (i think it's really worth the extra investment specially if you run your mining rig at home)

You can use The Voltage/Frequency curve editor(three lines next to Core Clock), There are some tutorial online about it.

maybe you haven't seen palit gamerock premium edition before, but is much better than asus strix...... better cooler and incredible factory overclock, the difference is really really huge

you can check it in images below, awesome!!

oh, let me also show you my hashrate, probably better results achieved EVER with a gtx 1070, and without using any external fan or similar to freeze the cards

http://imgur.com/a/0o4mj

you can see also afterburner here

comment about results and give me the prize please xDD

p.d: i dont live in groenlandia xD, ambient room temperature about 28º

It's definitly a premium grade card, pretty expensive, i've never seen one of these !

Take a look at mine (1070 gaming x), it's almost unbelievable

http://imgur.com/a/FTKWQ

I think mine takes the prize xD

note: i paid 229€ on a refurbished deal on ldlc-pro

[Chipychop]

woooow, really awesome also, nice nice card

it's the first time I buy a palit graphic card and really happy with results, cooler is less noise than strix even

tell me how can I check efficiency in the miner please!!!

finally, I want to share my worries with all of you. I have just seen this calculator:

http://www.mycryptobuddy.com/ZCashMiningCalculator

this is real? is it possible? this calculator seems to apply dinamic difficulty for mining coins, so in 6 months nor eth nor zcash will be profitable unless very low electricity costs or free

tell me your impressions about it

There are a lot of good 1070 models that can run at really high sol/s, but the trade off is the little gain in sol/s vs the large increase in power.....



sure i can get about 510 - 520 sol/s at 205w [2.5 efficiency] - about $1.5 a day in power

but i can get about 470 sol/s at 135w [3.5 efficiency] - about $1 a day in power

50% increase in power cost for a 8% increase in sol/s is not a very good plan if you want to make money.

Unless of coarse you have free power...

is it good enough for 980ti g1 gaming?

I wish all my cards had these numbers. A mix of EVGA 1070 FTW cards (08G-P4-6276-KR, 08G-P4-6276-RX, 08G-P4-6676-KR)

Some explanation of why the gpu 5 gives less speed of mine, the overclock is identical to the gpu1 and gpu4 but the watts go up and down in the gpu5 and never rise of 75 watts. All gpus are evga 1060 single fan.

I think:
1) The price of the coin is also used in the calculations, so you can only know what the profitability will be in 6 months if you know what the price will be in 6 months.
2) If some miners stop mining as (because) profitability decreases, dynamic difficulty should adjust to keep the block rate constant. So difficulty could decrease in this case, which will affect (adjust) profitability.

Power consumption is really bad on gtx 9xx series.
Compare with gtx 10xx series

is it good enough for 980ti g1 gaming? 

It's common for Maxwell NVIDIA cards, got the same effeciency for GTX970: 280 sol/s with ~140W power consumption, i.e 2 sol/W, for Pascal cards it is about 3 sol/W, depending on overclocking/downclocking settings

You can disable developer fee by adding "--fee 0" to your miner parameters
