Doesn't SMOS use EBWF not DSTM?

AFB line Delta fans are a lot quieter than the famed FFB line fans and their derivatives - AFB are a "whoosh" of the air moving, not a "scream" of the many-bladed prop interacting with the many-bladed flow director.
Innosilicon used AFB line fans (but the HIGH END ones) on the A2 and they're not quiet but they don't "scream" from 2+ rooms away.

AFB fans also have a LONG lifespan at high temp 100% speed operation - not quite up to the old Rotron Muffin series but the Deltas are also moving a LOT more air and spinning at a lot higher RPM.


 And now for some MAJOR wierdness - anyone else notice that 1070 prices on Newegg are THE SAME OR HIGHER today as 1070 ti prices?

 Anyone have a clue why 1070 prices would JUMP by $50 or more over the last couple days?

 It is - no "reach around AND UNDER issues, or "pull the card to get to it" issues.

 Shouldn't matter on a reliable rig though.

 2 molex risers per chain CAN be an issue - the connector is fine, the WIRING is often not enough to support 150 watts and in the case of EVGA they specify that the connection ON THE POWER SUPPLY END is only rated for 75.

 It's possible to modify a "dual molex to PCI-E" adapter to use one MOLEX, but I don't recommend it unless you're an experienced tech and KNOW what you are doing.
 It's just easier to plug BOTH molex into the same MOLEX "string" from the power supply - since it's only ONE riser, it's not an "overload" issue.

 There ARE folks that make "single MOLEX to PCI-E 6-pin" adapters though - I've got a few around that apparently were provided with video cards at some point, and went into my "keep this, it might be useful eventually" box.

 The reference cards should all be the same, as the guts are entirely provided by AMD.

 Aftermarket cards will vary a LOT though - like that Sapphire Nitro+ model with the INSANE 3 power connector setup.


 My single STOCK Vega 56 gets 1940-1950 consistantly long-term, I've not bothered playing with the BIOS as I'm not sure how long it's going to be pointed at Monero mining and it doesn't NEED a modded BIOS for it's later "long-term" home.

 eBay pricing on miners doesn't count - folks ALWAYS try to gouge there, and far too often get away with it due to folks with more money than sense.


 Most miners are BADLY spoiled, an ROI of less than a year is AMAZINGLY FANTASTICALLY GOOD when you compare it to most things you can invest your money into.
 Tradeoff is that it IS higher risk than most of those other investments.


 If Bitcoin stays above $12000, an 821/841 or S9 should easily achieve ROI in a year at the $3000 level (presuming the S9 don't lose a hashboard or die) if you have a SANE electric price to mine with.

 Folks paying over 5c/kwh are killing THEIR OWN chance at ROI if they insist on mining Bitcoin itself through excessive overhead cost.

Does claymore's monitor work with ANY other miner?

 Might I suggest trying Ethmonitor instead, which supports quite a few different mining programs?

 The one Zotac Mini model of the 1070 ti for me performed identically to my EVGA SC models, except it runs a little warmer due to the smaller cooling setup.
 I'm not buying more though due to the "sleeve bearing fan" issue - same reason I refuse to buy any more Gigabyte cards except PERHAPS the Aorus.

 The Amp Extreme line from Zotac, like the Aorus line from Gigabyte, does specify "ball bearing" fans - my issue with those is that the power connector setup makes powering multi-cards a lot tougher.

 110 watts as set as the power limit under Linux using Nvidia-settings, or reported by nvidia-smi in either Linux or Windows (or calculated from the %TDP setting in something like Afterburner).

 At the wall will vary more due to power supply efficiency curves.

'
 69% power limit set in Afterburner is 124 watts - something funky going on there.

 Probably the same sort of thing I've seen on "short efficiency spikes" in EBWF where it will report one card at way low power draw but normal hashrate - momentary down spike on power JUST as EBWF looked at it.

 You missed ZEC almost tripling in price over the 2-3 weeks after your post.

 8-P

 It comes with an adapter for 2 x 6-pin to 1 x 8-pin.
 The non-extreme Aorus has the same "base" TDP as my EVGA SC cards - 250 watts - which is safe enough to run from a single EVGA 8+6 dual cable if you're not pushing the card past rated TDP.

 Probably their normal "wide swing" on payout as the market shifts.
 The miner is semi-realtime, the web page is a snapshot.

Ampere is the generation AFTER Volta, as I recall - and it won't be SOON.

 2019 at the earliest, most like 2020.

 I have to wonder if they are going to use "Ohm" for the generation after Ampere.



 For those that don't get the references, "Volt" as the standard unit of electrical potential is named after Volta, Ampere as the standard unit of current flow named after.....Ampere of course, and Ohm is the standard unit of resistance named after Ohm....

Technically, I'm pretty sure ALL drywall is fire rated - but the rating (normally given in hours) varies with the thickness.
Then there's concrete board (which is in my planning for MY shelf/racks as a seperator since the standard 3'x5' size is cheap and big enough to isolate each unit from the next).

 They need to get used to it, we're not going to see new miner generations pretty much every year OR OFTEN LESS any more, as SHA256 miners have caught up to semiconductor state-of-the-art as of the current models.

 Do note that the S9 has already been out for a year and change, which ALREADY makes it Bitmain's longest-lasting "current model" - and it's looking likely to be that for another year or even 2.

 Then the NEXT generation is likely to last more like 4-5 years, since the S9 was designed almost 2 years after the 14/16nm node started seeing production.


 For that matter, if you were an early adopter on the S5 or SP20, you had something like a year and a half, perhaps 2 years with LOW electric power rates, to be able to achieve ROI - and the S7 is still profitable NOW and has been consistantly profitable it's entire existance so far if you had low power rates.

 Better yet - Innosilicon A2 is *3* years old, and they're been consistently profitable at anything under 5 cent power (and possibly 6) for their entire existence - but to be fair they've had a lot less competition 'till this year than has been the norm in SHA256.

 Delta fans are known for "move gigantic amounts of air for years at a time", not for "quiet".

 There's a reason some of their models are known as "screamers"....

 The Newegg invoice shows as dollars.

Initial 821 model is "officially" 11TH / 1200 watts

 They also announced an "841" model at 13TH / 1200 watts - but it appears that one won't show up 'till they've done at least one batch of the 821 models, and they haven't specified ANY sort of a timeframe on the 841 so it could be longer.

 They also announced an "861" power supply included model, again no timeframe and if it's like the 761 it's "China market only" intended.


 As to how they can manage higher hashrate at the same power - they probably have to use more chips running at less hash per chip but lower voltage so lower power and higher efficiency.
 Think Antminer T9 vs Antminer S9, same exact concept.

 There IS such a thing, but they're not common.

 Since you probably should only be running 1 riser from a molex string though, it's really not hard to plug both molex connectors into that one string.

 EVGA in specific has stated on their web site in the forums that their "peripheral" connections are only rated 75 watts per STRING.

 I've NEVER seen interference with the MOLEX or PCI-E connectors on the "3 way cards" with a backplate GPU - though I can see a possibility of the "latch" on the PCI-E power cable being a tight fit.
 If I'm going to use PCI-E power to the riser though, I just go with a straight PCI-E riser not a 3-way.

 MY main issue is they put the dangerous and worthless SATA power connector on the end of the card, where it's easier to route the riser power to - I'd rather see the MOLEX connector there.

 The right-angle adapter IS a bit annoying, but there are some folks that offer the traditional "straight out" adapter with those risers.
 I CAN see them being an issue on the B250 Mining Expert for all but ONE row of 1x slots as you point out, but they shouldn't be a significant issue on any other motherboard I am aware of.
