Can someone to into a bit more detail on what they've done to get 8 or 9 GPUs working on this board using the M.2 slots and adapters?  I've been able to get 7 GPUs working fine, but can't seem to get an 8th to be recognized when using the M.2 slot/adapter.  I know Win10 has the 8 GPU limit, and was hoping to squeeze in one more card.

Have the latest bios with 'Above 4G' enabled and slots set to Gen 1.  Latest Nvidia drivers and all the latest W10 patches.

Hey Claymore, any chance you could add a tweak to the miner in one of the upcoming versions that will let someone just straight up mine one of the secondary coins and not mine any ETH?  I know you can jack up the DCRI up, but I'm sure there's folks out there that may want to 100% mine SIA, Decred, LBRY, etc.

Well, the simplest way I can think of would be to create two batch files to launch the miner, one pointing to each address. Then just use windows Task Manager to set up tasks killing the current running miner and launch the other batch file at the intervals you want.

That's a total kludge, and there's all sorts of things that could go wrong, but with enough tweaking/testing it's doable.

That I don't disagree with, people really should spend the few minutes it takes to figure out the cost / benefit of dual mining and they may see they'd make more just straight up single mining ETH.

I do understand difficulty, but if he can make his miner more efficient than all other miners, while that would certainly raise the difficulty due to the overall increased hash rate, his miners (and Claymore himself with his dev fee) would have a larger portion of that hash rate in comparison to everyone else, which translates to a larger portion of the overall mined coins at the expense of the people using the other mining applications (until the other mining applications come up with their improved version).  Not to mention, improvements to his miner will drive more people to use his miner.  So yes, he does have motivation to improve his miner.

So...not sure how you came to that conclusion.  I'm sure Claymore wants to optimize the miner for any / all cards as much as possible.  The more efficient the miner, the more shares / MH he's going to get from each person that uses his miner...

Anyone know why Claymore miner would throw a '287c / checkread timeout' error when connecting to this proxy?


It will just continue to do that indefinitely.  I know I could just use Ethminer, but would like to understand why Claymore isn't working.  Anyone have any ideas?

I've been having some issues with fan control of my GPU's in Windows and I've tried MSI Afterburner and EVGA Precision XOC.  For some reason, even if I set those to set the overclocks for my cards on startup (which they do), the fans never kick on if I've got it set in Auto mode.  (Haven't tried just setting a single fan speed b/c I'd rather they ramp up and not stay full blast the whole time.)  I don't know if it's because they're on the risers or not, but does anyone know any windows based command line utilities that will allow me to set GPU/Memory Clocks and Fan Speed/Curves through a command line in a windows batch file?  I know Coolbits is out there for Linux, and I've seen a few versions that are 12+ years old that are supposedly windows based, but not sure I'm willing to try them.

So, random question as I jump back into some coin mining and trying to build the most efficient rigs.  What drives a cards power consumption down the most?  Lowering Power Limit, Core Clock or Memory Clock?  In particular, I've got some 1070's I'm trying to mine ETH with, and while I can get them to 30-31 MH, can't seem to get the card below 110W draw or so.

While I'd love to use BTC, I don't think so.  Mainly due to the fact that I can't really purchase most things I'm interested in with BTC.  If I could use BTC to purchase items from Amazon or Newegg, then, yeah, I would, but I already own 2 pairs of Alpaca socks and there's not much else I want that I can use BTC for.

Recently I've come to the realization that I just won't see RoI on my ASIC pre-orders unless BTC spikes pricewise, and I personally don't think that's going to happen so I decided to pull the plug and put in cancellations for the orders I had in place.  Of course I could be wrong, and if I am, all the better for you folks that tough it out.

All in all I had 4 Preorders with BFL, and 2/3 orders with BTCFPGA.  They've all been cancelled and I've received all my money back with just a little bit of hassle.

BFL

Had 4 separate pre-orders placed in the Sept-October timeframe.  Sent an email describing my exact orders, the dates and information on 12/09/12 @ 7:04 PM.  By 12/10/12 @ 4:30 PM all the orders/payments had been refunded through Paypal without a problem.

BTCFPGA

Had a bit of a hitch with BTCFPGA, partially due to my own screw-up.  Put in a preorder in early November, but accidentally put in the wrong email address as mine.  Never received the verification info, so I called Tom, spoke with him, and after a few calls, he cancelled the original order, and credited me the amount on a new account (with the proper email address), and I put in another order.  Put in a second pre-order a few days later.  Sent in a cancellation request on 11/22, Tom responded on 11/23 and I had a refund for one of the pre-orders on 11/24.  Assuming there was just some delays due to Turkey day and some confusion due to the first cancellation/credit, I sent an email to Tom/Dave about the other refund on 11/25, 11/27 and 12/10 and received no response.  Finally had to dispute the CC transaction and received my refund on 12/15.  I hated to go the dispute route, b/c I think Tom/Dave were doing the right thing, but there was some confusion around the original order/cancellation/credit and I think they might just be overloaded.

So, all in all, 6 ASIC orders, cancelled, without too much of a problem (other than the minor hiccups with BTCFPGA).  I've had fun with BTC mining over the past year or two, and wish everyone luck.

That's actually not bad.  Anything used that's more than 6 months old and half is probably a normal rate you'd see on eBay.

I tell you, I've been running the numbers, and I'm beginning to wonder if ASIC's are even going to be able to cut the mustard.  Figure the most efficient unit announced so far is ASIC at 60 GH/60 Watts for $1,299 and the most powerful per dollar is the BTCGPGA at 72GH/80-120 Watts for $1,069.

So, let's kick in a _conservative_ difficulty increase of 10x, and I say conservative because BFL has already said they have enough orders to bump the network at least that high.  With power costs of .10/kwh and a BTC/$ rate of $12.50, the hardware breakeven is:

BFL: 132 Days
BTCFPGA: 88 Days

So at _best_ you're looking at a minimum of 3 months before you can break even, and that's assuming the difficulty doesn't ramp up higher during that time, which is rediculous.  I'm beginning to think that if $/BTC doesn't jump drastically or BFL/BFGA don't increase their hashing/watt/$ drastically, you could easily end up in a situation where you never actually break even.

I wouldn't be surprised if we see total network hashrate dip below 20 TH in the next month or two (assuming ASIC's aren't in the mix).  I for one have pulled the plug on my miners.  Even with the hardware long payed off and a decent power rate of .10 / Kwh, I'm paying $9 in power costs to make $10 in BTC.  Just not worth the effort/aggravation.  I think in the next week or two, more people will see that and only folks will really low power rates or FPGA's are going to stick it out.

There's definitely some merit to this, but remember, the exact same thing happens with Video Cards, every 9-12 months the new GPU cards hit the market and are more efficient at mining.  Of course video cards are much less expensive than the current round of ASIC's and can be resold.

Mt Red acting wonky for anyone else, or is it just me?

You're assuming that there will be steady or increased demand for BTC. 

Yeah, I'm pretty much done mining for the time being unless things change drastically.  Currently for every $1 I earn in BTC, it would cost me $0.75 in power.  While it's still profitable, I'll make more selling the cards I have now than I would in a few years of mining at that rate.

Down to the last 18 blocks.  Less than 3 hours till split...

Ah, shit happens.  You can't blame Dave or Tom.  I can't imagine either of them isn't working their arse off to make things work and they probably haven't gotten much sleep lately.  Regardless of who your hoping to get your ASIC through, we're looking at brand new tech and there's bound to be bumps.

And for all the dinks ready to jump in with the "I told you ASIC was a Scam!"  This is for you...


Seriously, there's no way all these different vendors, some of which dislike each other a great deal, are in on some massive "Let's screw with people's with some vaporware!" plot.  We'll get there, it's just gonna take some time.
