Nice to see you ranked my favorite card (MSI 470) as #1.  I completely agree... tried a few others but ended up selling them and now running a full 4 rigs of 24x MSI 470 dual mining ETH + DCR.  It's a great set up and super easy to mod the bios on those cards! Never had an issue with any of them, other than just 1 that i can't overclock more than 1850 mhz but I will gladly take that overall success rate! They run cool and quiet and also look amazing! Can't beat them in my book if your are doing anything other than ZEC mining. The sad thing is that now they are almost all gone (at least new ones). Nearly impossible to find online for anything close to retail. A few B&M stores have a few left but sadly, none are within driving distance. I guess I am have pretty much tapped out my house capacity wise anyway, so maybe it's good they are almost gone so as to avoid tempting me to build more rigs lol.

There are a number of ways to go, and to add to the list, my method for my 4 rigs has been this:

1- Purchase OEM license for Windows 7 on ebay for $20. This is completely legit due to Microsoft OEM business model. The one caveat is that you have to do smart phone activation but it has worked flawlessly for me on 4 rigs.

2- After install of W7, upgrade to Windows 10 for free via Microsoft's "Assistive Technology" program.

In my searches, this was the cheapest and most legit way to get to W10, although certainly others may have found a better combination.

One thing that is not debatable though is that if you are planning to go with 6 or 7 GPU's, save your self a TON of hassle and go with Windows 10!  I wasted many hours trying to get my first rig past the 4-5 GPU mark on W7 to no avail... once i upgraded to W10, I was EASILY able to get 6 working on the first try, with no extra steps (like running registry mods, etc) required.

Cool! Thanks to you and the others that replied. I just got it in the mail so will work on setting it up this weekend. I will likely just try moving something like .25 ETH from a couple of places to it first to make sure i understand it all and don't risk losing a large amount. but seems pretty straight forward from what I've seen.

hey everyone... I know it's a bit off-topic but was wondering if anyone here is using the Ledger Nano-S hardware wallet to store ETH/BTC.  I've got one coming tomorrow and was just wondering if there are any gotchas or things to look out for before moving some coins onto it.

You know what is really amazing?  Not so much that there are still racists in our midst... there always will be... but it's baffling that in 2017, when there is soooo much attention against racist acts and comments (and rightfully so), that some people are STILL willing post that crap!  Seriously man, how about you educate yourself... maybe watch a few documentaries about the holocaust... then maybe you will think twice before posting your racist BS.

Hey everyone... I am planning a re-build of my first mining rig. Currently, it's 4 MSI 470's on an ASRock x99 mobo with an i7-6800k & 16GB of RAM.  Obviously, those higher end components are not not being optimized by my mining opereations, so I am going to use that core Mobo/CPU/RAM to build a new personal/music production PC.

So, i have a Biostar TB85/G3258 CPU/8GB RAM + 1200W Plat PSU ready to go and 2 more MSI 470s arriving tomorrow for this re-build.

But, here's the issue... this rig with 4 GPUs is not able to dual mine ETH + DCR.  Since it runs ETH only and XMR flawlessly and there is no power headroom issue (1KW PSU), it seems likely that there is a "problem" GPU that can't handle the extra stress of dual mining.  I have a good idea which one is likely as it has never been able to do more than 1850 clock speed, while the other 3 can easily do 1950.  What I would LIKE to do is identify for sure which one (hopefully only 1) is causing the problem and move that to my new personal/music PC since I will only be single mining ETH or XMR on that overnight or when I'm not using it for music production.

So... the question is... how best to prove which one is the "bad" one.  I think the best way is to do a negative test, meaning running 3 of the 4 cards only and seeing if it can dual mine without crashing.  But, I am not sure how to do this, other than literally unplugging the GPU, which I would prefer not to do if possible.

I thought I remembered that Claymore's miners allow to turn off any single (or multiple) GPUs but i looked through the instructions and didn't see this mentioned anywhere. I could have just missed it but wondering if anyone here knows how to do that?  If so, is it something done within the .bat file?

Yeah, that was my thought as well when buying 4 rigs worth of 470 4GB over the past 6 months. However, I have heard that the potential life is likely longer on the 8GB variety due to ever-expanding difficulties of mining algos, etc.  While that in theory may have some validity, I doubt the 4GB versions will be ineffective any time soon. I fully expect them to very productive at least through the end of 2017 and hopefully beyond. Personally, I think that ETH will go POC before the 4GB 400 series becomes ineffective in mining it, so i am happy with my 4gb versions that I got for much cheaper than the 8gb variety.

Hate to break it to you but that price rise in 470's (even used ones) probably has very little (if anything) to do with brexit.  In fact, prices of both 470 & 480 have gone through the roof due to 1) phase out preparing for release of 500 series and 2) huge spike in demand for good mining GPUs since the huge spike in alt coin prices about 6 weeks ago.  These 2 factors, combined with the fact that the early reviews on the 500 series GPUs are far from glowing (about same hash-rate with more power draw and big issues getting more than 4 GPUs to work per rig), mean that demand for 470/480 is probably near an all-time high, but of course, there is now very limited supply (esp new ones), so as a result, prices of sky-rocketed.  Indeed, I tracked a few sales of used 470s on ebay recently and they went for about $20-$30 more than I paid for new ones about 4-5 weeks ago, just before this huge shortage began.  The new ones are even tougher to get... many ebay and other 3rd party sellers are at least asking close to $300 already, and it seems likely that will go up given the issues with the 500 series. Even though I got a hold of enough 470s to fully stock my four 6-GPU rigs, I[m beginning to wish I would have scooped up a couple dozen for around the $160-$170 each they were only a couple months ago. Live and learn I guess...

Exactly! That 24 you were getting on your 480 was before strapping and tweaking. So, don't be sad with your 480 because apples to apples, it's very likely going to be a better performer (hash-rate to power ratio) than a 580 as those will use more power but only provide very marginal (if any) higher hash than a relative 480.  There are numerous comparisons hitting youtube where you can see for yourself. The 500 series are simply a re-branding of the 400 series so its not a surprise to most that there is no big gain. In fact, the 470s still seem to be the king of altcoing mining (except for ZEC)... especially with all of the driver issues plaguing miners trying to get 6x500 rigs up and running. Yes, some experts in power management may be able to get their 480's close to the power draw of a 470 but for the vast majority of miners, the current order of best ratios is:  470, 480, 570, 580. Personally, I would be very wary of going gung-ho on 500 series GPUs... especially that power-sucking 580.

Cool... cuz my 3 1200W Plat PSU's are all at around 1000w... so right in that sweet-spot range

Yeah, I'm not sure what this supposed issue with Hynix RAM is on MSI 400 series. I really wonder if it's people trying to aritficially reduce the demand for the remaining few new ones still in the market so they can hoard them themselves. I personally have been running 21 MSI 470's for between 2-7 months... 17 of the 21 have Hynix and the other 4 have Samsung.  To date, have not had 1 issue with any of these cards, including all 17 Hynix ones. In fact, 4 of these have probably been in use for more than a year as I bought them used from Philima1957. So again, not real sure what's driving a few people to bash Hynix but i have not experienced or heard reliable accounts of any real issues.

hey Phil... regarding your summer pare-down of rigs/GPUs... I think you said you do it because your electricity rates nearly double in the summer, correct?  This makes sense in previous years but with the huge upswing in the price of Alts the last few months, wouldn't you still be pretty profitable with your rigs even pay 2x for electricity?

For instance, you said you are currently at about 16 days to ROI a 1080ti... so even if your rates are 2x in the summer, wouldn't that still mean you could ROI them in about a month?  Maybe I'm missing something (probably something to do with your solar array) but I couldn't figure it out... unless maybe it's also a heat/safety issue.  I am personally wondering what will happen to me in the summer. My rates don't increase and it rarely gets above 80-85 here in Oregon, but my house's A/C isn't exactly powerful so wondering how hot it's going to get before I have to consider turning off rigs on occasion. Currently, I have 1 each in my garage, den, dining area, and 1 upstairs bedroom. I would consider moving 1 or more to the garage but it has zero ventilation unless i open the garage door, so I doubt that would be a solution.

Based on what I've read from user experiences, as well as seeing a couple of benchmarking videos on youtube, 570/580s are not only most certainly not game-changers, but are actually less effective from a hash-rate/wattage ratio.  I think the 580s are the worst as they consume a lot of extra power but barely provide any additional hash-rate.  Seems like a really stupid move by AMD... EOLing the 400 series to release essentially the same performance that uses more power. I guess they are banking big on the gaming community getting sucked into these since I'm pretty sure most miners aren't going to go crazy over them.  I still need to get a hold of a couple of MSI 470s but now they are getting even tougher to find.

100% agree!  Prior to release of 9.2, I had 3 6x470 rigs trying to mine ETH+DRC.  2 ran fine with very few crashes but hashrate flux was all over the place. the 3rd rig would only run for maybe 2-3 hours tops, and that was with -dcri 16!  Now, since installing 9.2, that 3rd rig has been up 24 hours straight and all 3 rigs are actually getting better overall actual average hashrate because the fluxing issue has been resolved.  On this note, I would urge those that are complaining about a 2-3% PERCEIVED drop with 9.2 to look at your ACTUAL results in your pool vs 9.1 or 9.2.  My ETH trend line is at or above what it was before and my DCR payout frequency is better as well because there appear to be a lot fewer bad DCR shares when digging into the log files.

My next test will be to start moving up -dcri a bit on all 3 rigs but the BIG test is going to be trying 9.2 on my 4th rig (4x470). That one has not been able to dual mine ETH+DCR for some unknown reason for several weeks, despite plenty of headroom wattage wise.  My suspicion is that one of the GPUs is more sensitive to the harder work of dual mining than the other 3 (this has been a problem GPU that can only be OC'd to 1850 max).  However, I think the issue with the 3rd rig was similar because that ran dual for 24+ hours when i only had 4 GPUs hooked up to it.  Hoping 9.2 will do its magic on that 4 card rig as well!

Thanks again Claymore! Great job on this update!

Completely agree!  People, please read at least the last few pages before posting your problems because 95% of the time, the answers are there. Furthermore, how about a bit of patience?  If you would have bothered to read back just a bit, you would know that the slight speed decrease has been acknowledged and the fix is under works for release in the next few days.

However, there are other things to take into account with v9.2. If you are seeing say a 3-5% decrease in your MAX speed, that doesn't necessarily mean your overall average speed is less. In fact, at least for me (and I suspect many others), my effective average h/r is at least as good as v9/9.1.  This is because while my max speed was indeed about 162 for 6x470 on ETH, it would frequently drop down into the low 150's and even low 140's. That means the actual average h/r was more like probably in the low to mid 150's at best.  Now, with 9.2, I only dropped to about 159, but the huge fluxes are gone... drops at worst to like 157.5 but not very often at all.

Similar thing with DCR... yes my rate dropped a bit but i took a look through the log file and didn't see hardly any bad shares... which were hitting a LOT with the previous versions. So again, I submit that the vast majority of people are either at least as good or better with 9.2.

Furthermore... I want to point out that the BIG issue we were all facing (the change to DCR daemon that prohibited us all from mining any DCR) was fixed very quickly, and this was the most important aspect of 9.2 in my mind. To me, getting the added stability is an extra bonus. Even if you are in the minority and seeing a real slight increase to your DCR rate, I'm sure your are still WAY ahead of v8 of just a few weeks ago since v9 has provided about 50% increase to DCR rates.

Big thanks to Claymore for making this a priority and getting the fixes out ASAP!

Yeah, that was a rude awaking this morning when i saw all 3 of my ETH+DCR getting nothing but DCR rejects. Even changed pools on one only to then see the post on CoinMine.PL that the Decred daemon has changed so miners will not work until updated. Thanks to Claymore for addressing this quickly. Hopefully it's not a hard thing to fix since DCR is hovering around $17 now!

Well, this thread is at least good for a hearty laugh. Let's recap:

1- a few losers with minimal knowledge of mining, hear about the explosion in BTC & Altcoin prices and decided to hatch a scam
2- after writing up some obviously contrived technical specs, they open a new account on various forums to begin to try to perpetrate their scam
3- newbie with almost no prior activity here posts obviously made-up horse-shyt... including the always laughable "I am not affiliated with this product" BS... trying to convince people this is the best thing since sliced bread
4- after countless, experienced miners call out what utter BS this "product" is, OP continues to go overboard trying to defend it... including referencing 3-year old tech articles that don't have shyt to do with the product, and contrived videos with obvious actors reading BS from cue cards lol
5- OP continues getting slammed and eventually goes away when they realize nobody here is going to give the BS company $1
6- OP and cohorts continue their career at local McDonalds, which is quite ironic given that's the address they used for this supposed company lol

did I miss anything?

Phil makes a good point about ZEC/Nvidia but at least to me, getting into that side really only makes sense if you have multiple rigs to spread your hash among.  This is because, as far as I know, ZEC is the ONLY coin you're going to get better hash-rate using Nvidia on... and even with that extra h/r comes higher initial costs (in most cases), so your ROI may not be as good as it seems on the surface.  But, even if you can get a great deal on Nvidia to lower your ROI, you are still somewhat painting yourself into a corner if you go ONLY Nvidia, because almost all other minable coins on the market are better mined with AMD GPUs.  You not only have ETH, DCR, & XMR, but there are a bunch of other profitable coins using the ETHash algo (so options after ETH goes POS), not to mention the other secondary coins like LBRY/PASC/etc, that can be mined in conjunction with ETHash using Claymore dual.  I am not down on ZEC by any means... in fact, if I build another rig I might go nvidia to maximize in that area. I'm just saying that if you only have 1, probably AMD is more flexible because it offers better hash-rates on more algos... at least on a dollar for dollar basis.

If you can really get a 470 8gb for 187, i would totally go for it... especially since it's only 14 more than the 470 4gb.  i personally own over 20 MSI 470's but they are the 4gb variety because when I was buying most of them here in the US, the price difference was like $40-$50. To be able to future-proof with 2x VRAM for only 14, it's a no-brainer in m my book.  also, imo, the 470 8gb is by far the best buy in this list at those prices. it wouldn't make sense to go with the 480 4gb for same 187, and imo, not worth the extra 34 to go 480 8gb.  For most people, there will only be a slightly better hash-rate with 480 vs 470, but the 480 also suck more wattage so the actual profitability between the 2 is almost a wash, aside from initial cost.

It's true that Dash is only able to be mined via ASICs and among those, Baikal seems to have the best product line. I have owned 1 of their Minis (this is actually an FPGA, not true ASIC, as it can mine multiple algos) for about 4-5 weeks and it's awesome! Super easy to set up and has run 100% up time since plugging it in (wish i could say the same for my 4 GPU-based mining rigs lol).

Unfortunately, you came in at really bad time because the explosion of Dash price recently has caused a world-wide shortage of X11 ASIC/FPGA.  If you can find them at all (from any brand) they have been listed at 2-4x their original price.  Even if Dash goes back to $100, that huge markup makes the ROI period way to long, so my advice is to keep watching Baikal's stock and try to get in when they release their next batch.

I can't speak for Sia or Libr but for sure you will have a problem dual mining DCR with that rig as is. As an example, I have been running 2 6x470 rigs (on 1200w PSUs) and with ETH only, it pulls about 820-830W. But with ETH+DCR, it runs around 970-1000w on v9 with DCR set to 27-30.  I just built a 3rd rig and am in tweaking mode currently trying to get it to run dual effeciently. Even with DCR set to only 20, it still pulls about 940W.  Most people here recomend not exceding 85% load on your PSU.  That's why i have set my personal limit to 1kw on my 1200w PSUs (about 83%) or maybe a bit lower. Given you already at that ~85% thresshold, I would not recommend trying to dual mine with that rig... unless you are willing to turn down intensity on ETH & lower your overclocks. Even then, would probably be challenging but good luck!
