TheStilt in his celebrated BIOS mods for the R9 290 achieved ballpark 15% savings on his NOT UNDERVOLTED version of the BIOS (personal testing on my own cards when I was first checking those out) - and he didn't disable ALL of the video out capabilities on the GPU, just most of them.
 I doubt a factory mod that disables ALL such circuitry would achieve less, and should achieve a bit more.

 I do concede that it's an estimate, and I wouldn't be shocked at more like 10% given upgrades in tech since then, but at least one source was QUOTING "10-30%" for that figure on the P106-100.



 Given GTX 1060 pricing is now climbing, $270 right now wouldn't be a bad price for the P106-100 - significantly less than the consumer 6GB versions in almost all cases right now - even if it IS quite a bit higher than reported "MSRP" was supposed to be per all of the rumors of pricing.

 30 out of a 1060 6GB varient wouldn't be a big stretch, upgraded memory timings in the BIOS plus some OC on the memory could account for that.
 35 - that's a bit of a stretch. I'd have to see that to believe it.

 On the other hand, even at 30 and if it's lower than "standard 1060 6GB MSRP" it's going to get some attention, especially with the extreme shortage on other good ETH mining cards and their inflated pricing.

 It's scary when I saw a 1070 (MSI gaming, NOT a water-cooled model) at the SAME price as their lowest-cost 1080 ti (not 1080, 1080 ti that was NOT a typo).
 I do grant it was the HIGHEST priced 1070 on Newegg at the time - but STILL crazy.

 Looks like 1060s are starting to get hit by the "nothing else to buy, grab these" shortages and price-climb too.



 It's debateable if Alibaba has more scams than eBay - but they both have issues with scammers.

 It did fix.
 It would have been nice for one of the devs to explain that before it fixed though.

 Up side - they DID at least try to give a timely warning, I saw messages about it a couple of places pretty quickly (not their fault if the messages weren't SEEN).

Ed actually has a few close competitors now, based on 24 hour average - 2 Curecoin team members doing merged FLDC, and long-time #2 "war" are also up there.
Going to be interesting to see if he does any rig upgrades to hold on to #1 all-time producer - as I understand it he's still running a bunch of 9xx series cards.
He's got some time though, war isn't quite matching the 24 hour average and is 2 billion points behind, while the others are over 10 billion back.

 Any clue about the massive price spike today? Had I known it was going to happen, I'd have waited on my last cashout and pulled in more like $15-20k instead of "only" 3k or so....

 The peak was VERY briefly above Curecoin in the 6600 ballpark on Bittrex....

 RX 580 needs BIOS mods AND a large overclock to get to 30 on ETH.
 GTX 1070 needs a good memory overclock and no more - and some will get to 31-32 if you have memory that overclocks particularly well.

 Power consumption is a tossup - they're close enough that specific card variations and tweeking can give the win to either side.

 At CURRENT pricing though, the GTX 1070 wins on hash/$ against the VERY FEW "available for sale" RX 580 listings I've seen this week, and marginally on availability, but BOTH the RX 580 AND the GTX 1070 are getting into "very short supply" issues, and pricing on both is inflated (more so for the RX though, since those are supposed to MSRP in the $200-$250 ballpark).

 GTX 1080 is about 20% better as a very rough ballpark on skein or zec - again, specific brand model and manufacturing tolerances will vary that figure. At CURRENT pricing, it's more like 5-10% more than a 1070, sometimes LESS then the higher-priced 1070 models, and availability doesn't seem to be an issue so far.

 ALL of this could change tomorrow, given the current demand vs supply conditions on any card that is even semi-decent for mining with.

 $10 a day seems a bit iffy right now, but $8-$9 should be easily achieved based on reported hashrates I've seen.


 I have not had good experiences with any suprnova pool, they seem to ALL work poorly or short you on shares.'
 I grant my sample size is small though, and some folks DO like those pools - but I've also seen a lot of "don't pay out what they should" complaints.

I'd recommend poking around on whattomine - not just the comparison page as that leaves OUT the Skein coins among other MORE PROFITABLE options - and look at moving to one or more of the more profitable options.

 You could also try the profitability page on Nicehash, but that focuses on their service and isn't always a good judge for mining actual coins - it does usually give you a direction to look at though.

 Having the new site up for testing and feedback on a different URL makes sense.

 (edit) except they're now forwarding the "www" address to the "new" address, which does NOT make sense and is now ticking me off again.

 That makes ZERO sense. The same number of coins are going to get mined no matter what the diff does, the same number of blocks are going to get created, etc.

 It doesn't affect ANYTHING that matters.

 It certainly does NOT affect "miners hording coins" in any way, shape, or form, as it affects ALL MINERS EQUALLY.

 Half right.

 Yes, most 1070 are capable of 30 Mh/s or very close.
 No, they are NOT available to buy almost everywhere for the last week or so - avaiability has gotten REAL spotty, almost down to RX 470/570/480/580 levels - though the price hasn't climbed AS MUCH yet, it's also headed up well into 1080 territory.

 People mining ETH on a 1070 are being kinda dumb though, those cards do a LOT better on other algos and coins for profitability.

 As the cards don't apparently actually exist yet, or are JUST (maybe) starting to show up, benchmarks don't exist for them yet.

 I don't know EU to USD conversion rate, dunno if that would be a reasonable price or not.

 more like 6 months minimum, and probably a good bit longer if ETH lives up to it's "planned phase-in" starting around the end of the year.

 Where the heck are you comming up with "a month"

Depends on the algo.

 For Bitcoin and it's derivatives, the Antminer S9 and R4 models are the most efficient.

 For Litecoin and it's derivatives, the Antminer L3+ but be ready for a LONG wait on them.

 For X11/X13/X15/qubit/one or two other algos I'm spacing at the moment, the Baikal.

 For overall most "income/watt used" BURST is probably the king, but it's only so-so on "income/$ invested" right now.

Keep in mind that Alibaba is pretty much the chinese version of eBay - they're nothing more than a marketplace.

Bitmain makes *2* power supply models now, but the low power one is 220v only, the high power one is 220 for full capacity 110 for about half.

Try checking in the marketplace here for some of the "breakout board" suppliers like sidehack or jabberwock.

More likely OP was thinking of Spondoolies, but they died - very few other folks around that made rack-mount miners EVER, and I'm pretty sure BitFury is the last one standing.

ETH is primarily wanting you to max your memory clocks - it would appear you've already done so.

 Keep in mind that manufacturing variations WILL change the capabilities of a specific card model, much less different cards from different or even the same manufacturer - just because one person got lucky on RAM and could overclock it to crazy levels doesn't mean YOUR card can match that.

 With that said, you should be able to drop your TDP a fair bit without having a noticeable effect on hashrate, which would help your efficiency quite a bit.



 With that said, wasting a 1070 on ETH mining is .... not a good idea, they are more profitable mining other stuff like the Skein-based coins, lbry and it's varients, the groetsl based coines, and usually ZEC and it's varients.
 It's not like you'll LOSE money mining ETH, you just aren't MAKING as much.

For stability, LINUX is the best choice (or one of the mining-specific LINUX variations) from the point of stability.

 AMD is widely reported to be having issues with Hynix not having enough HBM2 production to meet the demand for the consumer Vega cards (the PRO Vega Frontier edition has been released and is for sale, on Newegg among other sources, but that's a low-volume card).

This does NOT directly affect the RX series at all, what is probably limiting AMD there is lack of foundry capacity at GF to handle both the unexpected SURGE in demand for the RX 570/580 AND the ongoing demand for Ryzen, the demand for the XBox One X apus, ET CETERA - AND the fact of "lag time" between they can place an order for more chips and when they actually GET them weeks or even months later.
 AMD likely also doesn't want to risk over-ordering chips then having to hang on to them (with a lot of CASH tied up by excessive inventory) if the current cryptocoin mining demand drops unexpecedly - and they're probably making a lot more per chip WHILE the demand lasts, while worrying about what it's going to do to their market share WHEN the collapse happens and there are suddenly a ton of "used" cards on the market killing a lot of the demand for new ones.

 It is telling that the last "amendment" to the agreement between AMD and GF allows AMD to use OTHER foundries to make stuff, if they pay GF a "penalty" for each wafer made elsewhere. I keep wondering where they're going to find ANY spare capacity to use that part of the agreement, as TSMC is booked out solid as well and Samsung is pretty busy too with their own stuff and the NVidia GTX-1050(ti) making.

 While the Vega cards MIGHT be more powerfull for mining, it's unknown at this time if they will be powerfull ENOUGH to justify for mining at whatever price point they end up selling them at.
 The Fury wasn't exactly a popular card for mining in it's "new" heyday for that very reason, though at CURRENT pricing it's a pretty good choice.

 It looks more like a NVidia variation on the Pandaminer - using mobile versions of the cards, possibly modified a bit, like the Pandaminer uses mobile RX series cards.

 Some EVGA models are made by Seasonic.
 Some are made by SuperFlower (the G2 and P2 series in particular, VERY well done).
 Some are made by .... dunno.

 Corsair makes NONE of it's own power supplies, they contract them all out - and depending on who makes each model, they can be very good to very poor.

 Seasonic on the other hand DOES make all of it's own - and they are generally Very Good to Excellent (though I hate their "crap fan" choice on the Prime series and won't touch those).


 It's interesting to trace down who makes each brand - when you get down to it, I'm pretty sure there are only about 15 perhaps 20 actual "ATX power supply manufacturers" in the world, and almost all of their factories are in China or Taiwan.
 It's NOT quite as "centralised" as Hard Drive factories in Thailand though....
