1070 ti followed very closely by the 1080, if operated at their most efficient spot both will hit 4.4 easily with peaks pushing 4.7 sometimes (I don't count "peaks" where the power is temporarily WAY below the set point as those are statistical abberations).
 1080 ti will top 4.1 easily and might hit 4.2-4.3 with a lot of tweeking on a good card.
 1070 struggles to get TO 4 in my experience with several models, but will usually manage it with enough settings work - this specificially includes the Zotac Mini and the Gigabyte ITX.


 When you factor in total system power draw, the 1080 ti closes the gap a hair.
 The 1080 has more "upside" than the 1070 ti when both are run above the "most efficient point" but both drop efficiency pretty fast above about 115-120 watts, and the 1080 normally costs ballpark 10% more for a "same model" card.
 The only advantage to the 1070 is the lower entry price - but it's not THAT much lower than the 1070 ti, and at "most efficient point" for each card the 1070 gives up close to 15% hashrate while only being ballpark 10% cheaper for a "same model" card.

 It also depends on what's on sale and what prices are like in your area.

If you ask me this is how my logical thought would go:

1) Letter C is out, it is too expensive
2) Letter B is out, it has the same specs as Letter D but more expensive
3) Letter A is out, it is more expensive and samsung memory drives are more known for stability and 128gb is enough for a mining rig

So definitely i'd pick D:

Bitmain release date for any L3+ are now March 21st.  4 damn months. So they get you to buy the miner and they will mine with them for 4 months killing the value than release just as they did with D3.  Even worse they only take BCH so forcing a pump into BCH.  This company needs competition that is real because they killed D3 in the 3 months it took to get the D3 they were mining with them so difficutly rocketed up and we get no ROI on them!  Barely make anything off them.

This company has gotten to be crooked scammers that will get the miners to buy the equipment so they can mine the value out of the coin than dump them on the miners worthless!

I am starting to see a lot of talk about taxes.  
I have to admit that I am starting to get a little concerned about how I am going to file this year.  
I am not LLC'd into a mining company (however I have been kicking the idea around lately for better write offs and depreciation of equipment).  

How are you guys in the U.S. going to be doing it?  
Every payout/transaction/trade logged (from what I have seen, the way its supposed to be done but seems almost impossible!) or a snap shot of your portfolio on 12/31 and just 1099 as income?  
I have to admit that I really didn't think things through when I jumped into this and never really thought it would be as profitable as it has become for me.
It started as a hobby and turned into a borderline obsession HA HA!

Now I am looking back and starting to understand why you guys go through Nicehash for easier accounting!  
I have been a pool jumping fool over the last few months and its going to be pretty hard for me to track every transaction and trade...

yeah decent price for a 1070. that 1070 mini i bought from you does ~3.8 sol/watt, im happy with it.

but i figure i should go with a 1080 or 1080ti to try get more efficiency.. or is the 1070 the sweet spot as far as watts/hash?

Reducing dust and crud build-up is an important goal if you're going to be mining for any length of time. When dust builds up in a miner it blocks the heat transfer of course, but also allows airborne grease and oil to become trapped in the miner making a real mess. This acts like a nice little blanket over your chips/fets, sealing in the warm-ness.

These usually show up at my repair facility with burned chips and FETs. Fixable, but a mess.

The real problem of course is when that combination of lint and oil catches fire from an overstressed capacitor shorting plus 4,000 watts of +12v from the monster supply feeding several miners. Then the lack of a Halon system in your mining center becomes an issue....

And then there are the people who run miners in horse barns.......

sold some at 10200. now i want to grab a 1080 or 1080ti for the onda 250 build. i know i want evga but which variant, ti or non ti? Im more for watts/hash vs $/hash.

any favorites you guys use?

what are your guys preferred rams? / why?


Anyone picking up an S9 from the current batch?

see crazydane's config

Rule of thumb:

0. Ensure your board boots, press ON button, listen for beep, if not then reseat DDR3 RAM and ensure all cabling tight and secure
1. Most BIOS defaults at GPU0 for monitor (PCI slot closest to CPU)
2. To use ONDA onboard mobo graphics - you actually need to change BIOS
3. In use smOS or nvOC, no changes required in BIOS to get mining running.
4. Plug monitor at GPU0, save BIOS and let it run.
5. logically Win10 will probably same as above.
6. I use smOS Linux mostly for my rigs - for ease of deployment, except for VEGA/Win10 and older rigs 1080ti Equihash/nvOC

@citronick and other guys/gals with Onda D1800

Hi all. Are you able to run the Onda D1800 with nvOC? Or are you all on windows10?

To run nvoc properly, I think I need to disable the IGD.

I tried to disable the IGD in the bios.
I installed a pcie gpu(gtx1060) on pcie1 slot.
I connected a monitor to the gpu on pcie1.
I powered on, no display on the monitor.
I connected a monitor to the builtin vga on the board, no display on the monitor.

Am I doing something wrong? Help???

B Stock - EVGA GeForce GTX 1080 SC GAMING, 08G-P4-6283-KB, 8GB GDDR5X

How about CFM value for each fan ?

Hey guys, i know this is little off topic but i want to purchase few s9 and i cant login on bitmain site. I cant disable 2FA from google that i never activated. They are saying that i should take a picture from me holding my personal ID and send it to them, i dont know how secure is that so i tried to open new account and the SMS for the activation never arrives. Anyone has any sugestions?
Thanks

My Nov 21-30 S9 just had its shipment label created at 9:30 EST. Just saw it from UPS.
