@flamer283 I’ve seen this mainly with tpruvot’s ccminer, and alexis is a fork of it. it might be something in the code that’s more sensitive to 1) overclocking of main clocks and/or memory, 2) cpu processing power/throughput, 3) miner intensity value set too high (or auto setting choosing too high a value). I don’t ever recall seeing a thorough explanation. :/

If you’re not overclocking, don’t have a wimpy cpu, and aren’t trying to set intensity too high yourself, you can try setting intensity to a low value like -i 10, and work it up until you see the error again and use the last value that worked.

I don’t want to beat a dead horse, but I do want to share a FACT which I have found since I started solo mining.

I never passed any judgement in choosing solo vs. pool. My posts are still there to read, I don’t delete posts.

Today, I mined my 1000th coin since I started solo. The first day that I put the miners working solo was January 7th. I will politely allow you to do your own math. After you do your own math, I will politely allow you to come to your own conclusion about whether or not I should’ve chosen to solo mine. Regardless, I am happy that I did!! =o)

Pool: 110 coins per day. (That’s what you said).

Solo: 1000 coins ÷ 14 days = ~72 coins per day… :man_shrugging:

I’m not at all dissing your decision to solo mine, Jimmy. Look, you’ll probably hit some better luck solo mining and hit three blocks a day, who knows. I’ve merely been pointing out that the “blocks solved by you” stat on the pool site is just that; a stat, meaningless in a pplns reward scheme. At this point I’ll defer to the mods and call a truce here. ;) :grinning:

By the way, I don’t do windows mining any more, but if you’re willing to learn and use linux you could easily get ~780 MH/s out of each of those 1060’s. I’ll keep updating my analysis and can show how it was all done (when I get the time!).

@vigospqr
Not looking to argue. :) My guess is you’re likely under 30-35 years old, perhaps unmarried, still generating a career of sorts. Probably fine if you don’t have significant debts to cover in case of a “life event”. :thinking:

My view of cryptocoins is that there isn’t a shred of anything meaningful, physical or monetary as it relates to the real world, backing BTC or any altcoin. None. No real collateral whatsoever. (If you know of something, please show it to me.) The technology is open source.

If it all collapsed in an instant tomorrow, there would be no crisis in the world other than tears for those who lost their shirt investing large sums of money getting caught holding the bag. Talented devs would simply find another job programming something somewhere.

The only other real losers in the altcoin game would be AMD and nVidia.

But that’s my 0.02 BTC from someone over 50 and married with kids. ;)

@vigospqr

I have three rules of Crypto-Fight Club:

1. Mine altcoins that have proven developer support, are innovative, and don’t have scammer devs
2. Hold them, trade them for other ones, or cash out on Kraken when the time is “right” (matter of prefs/needs)
3. NEVER EVER EVER “INVEST” HARD-EARNED CASH

@bluebox it could be that Ubuntu is the reason behind my success.
Regarding overclocking it seems it will have to wait until I build dedicated miner as it seems that my “magic” does not allow me to change settings from nvidia-settings. I probably could change them from terminal, but I dont want to dig into that right now, so thank you for your help :)

I might try it sometime with a dual xeon/intelHD server I have and the 1030 out of my kid’s gamebox. I doubt we can get the fan+o/c controls to show up since I believe the settings cli and control panel rely on having the nvidia kernel mod loaded for that.

I did try other version of ccminers and ccminer-ghostlander is doing incredible ~735 kH/s :) Other miners are around 600 kH/s, so there is no doubt in my mind which one to use :) Now i just have to decide weather to stay and mine feathercoin or try some other coin which could potentially have higher growth…
By the way my I ask where did you get 1060 for such amazing price you mentioned in the other topic?

I got them from Amazon and Newegg. Last year they were readily available, though limited to two per purchase, so I bought two from each place, $215-220 each. These days, 1060’s are like hens teeth and cost a ridiculous amount (from suspicious vendors). I mean seriously — $550 for a 6160-KR?? :rofl: I ordered another Seasonic PSU to power my two trusty 970’s on the same rig; much better to keep using those than pay THAT kind of money for 1060’s.

1060’s were and still are the most efficient neoscrypt hash-per-watt option out there, especially when overclocked. Perhaps too many people read my ccminer topic… ;)

@ag2288

Yes, I’ve seen that before but couldn’t get it to work with my motherboard/cpu, originally an i5 but replaced with a Pentium because it was going to be a dedicated miner anyway. (I use CentOS too, not Ubuntu.) I do give up easier these days; you’d know if you have kids and thus no personal time. :rolling_eyes: :laughing:

If you can open the Nvidia Settings control panel and see the gpu in the list, you’re 90% there. The fan and clock settings will be greyed out/not shown until you add coolbits to your xorg conf file.

If your gpu isn’t listed in the xorg conf file, add it with nvidia-xconfig --enable-all-gpus (or just -a), then edit the file and add this in the Device section for the gpu:

    Option  "Coolbits" "12"

Then reboot and see if you get the control panel settings enabled. If you can’t use the control panel at all, you might still be able to control the fans from the cli, but it’s kind of an ugly command (I’ll go back to my old dual 970 pc and look it up). It could still be that you can’t access any overclocking or fan tools without the nvidia kernel module loaded, though; you are running it without a display driver after all. :thinking:

Welcome to the forum.
The p2pool ecosystem is growing for FTC ;)

see: http://p2pool.neoscrypt.de

Wasn’t so long ago I remember seeing only 6 or 8 nodes in that list. :)

I have been using give- me-coins since I started this mining adventure, and I have been royally screwed…

I have solved 39 blocks for them, and have only been paid out 1,093 coins. With a 40 coin block reward, it’s not difficult to see why I’m ready to spread my wings…

Not to belabor the point (I think I answered you in another thread), but just because you are noted as the solver of a block in a pool doesn’t mean you get the entire block reward.

All miners in a pool contribute their hash power to find the solution, and are given a percentage of the block reward based on that relative compute power, a.k.a share rate.

If it wasn’t done that way, then a pool wouldn’t be a pool; it would be the same thing as solo mining.

You weren’t getting screwed.

@ag2288 said in Novice building a Mining Rig:

Question for experienced users. Are those numbers reasonable?
First thing I have to do now is to dedicate 1060 only for CUDA calculations ie mining and use intel gpu for display graphics. Then I am open to other suggestions :)

If you have a base/boost 1506/1708 card, 600 seems right in line without o/c or miner optimizations.

You won’t be able to use video from your integrated graphics and use the gpu’s for mining, because the nvidia drivers must be loaded for mining and they cannot co-exist with the nouveau driver the integrated graphics will need. You’ll have to use one of the 1060’s (or a cheaper nvidia card that can use the same driver set) to drive your monitor.

The X process won’t exact any performance penalty on the gpu driving your monitor. (I’m assuming you’re not using the machine while mining for anything else…) Here’s my setup with 4 “identical” 1060’s, as you can see gpu0 is driving the monitor and runs the same temp as two others. gpu1 is the black sheep; it’s always run a few degrees warmer no matter what I do, but then not all children are the same either, eh? ;)

Take a look at my linux run-down of the four known & useable ccminer forks running different cuda versions. There wasn’t a 1060 driver compatible with cuda 9.1 when I did this, however I doubt there will be much difference from 9.0.

I can help with how to set up xorg.conf so you can access the fan and clock controls in the nvidia-setting control panel too, if you’d like.

@anema said in GTX 1070ti:

Btw What about molex to 6 pin is it okay to use it ? connect it directly to the PSU

“Molex” is a company name, not a specific pin configuration. The single row 4-pin used for old-school IDE/SCSI hard drives is a molex design, as is the 2-row 3-wide 6-pin config used for 75W GPU connectors. Either one will have heavier gauge wires, usually 18AWG or lower, as opposed to 26AWG or worse used in those SATA plugs.

Given the same amperage, the amount of heat generated in a wire drops with increased thickness of the wire. Physics 101. The lower the gauge number, the thicker the wire. The 16 or 18 gauge wires used in 4 or 6 pin molex connectors will generate much less heat than the 26 gauge wires used in some SATA connectors, which have much lower current ratings.

IF YOU KNOW WHAT YOU’RE DOING and have the proper measurement tools, you can check the current draw from your cards when fully utilized AND o/c set to max. If it’s below the current rating of your connector of choice then you’re ok to use it. Otherwise, best to err on the side of common sense and spend the few relative bucks and use the proper stuff, especially when you’re spending many hundreds of dollars per gpu. ;)

@lizhi three years ago quoted 7850 @ 40KH/s, 7970 @ 70KH/s on ccminer, so probably near that or less. I have a 5770 in my Mac, and ran it with nsgminer under Windows (bootcamped) I think it was in the 20’s, but don’t quote me on it.

For reference, a three year old Xeon 2695v2 does 56KH/s, and a core i7-4790K does 19KH/s. :laughing:

@jimmy24651

You can never learn enough about this stuff. ;)

Here’s the kind of thing you need: $39 8-pack of 2 foot long 6-pin male to 6+2 male 16 gauge wires to fit the usb risers you linked. :)

@anema

Yes, but do you see those black and yellow 6-pin to SATA connectors? Those are what you need to not use. For those risers, buy 6-pin to 6-pin male cables, one for each riser, and go straight from the PSU’s modular Peripheral IDE/SATA/Molex port straight to the riser just like the GPU power cables go from the PSU CPU/PCI-E ports to your cards.

It’s your call what you want to do though.

Just make sure the gauges on any cables you use are high enough to handle the current, up to 6.25A (75W), particularly if you’re overclocking. Otherwise you could overheat/melt them. Too many people try running two risers with big cards off of one serial SATA cable from the PSU because they don’t have enough modular ports (buy a better/bigger PSU, or at least a second one!!), they overclock the cards pulling full power, and… well… :fire:

@jimmy24651 said in Solo mining... patience is a virtue? ...or... am I doing something wrong?:

On the give-me-coins web site, when I look at statistics, I show that I have solved 44 blocks, but I have only been paid out 1,200 coins. Ok, my math was a little off, but the point is still made.

Oh my. TMI warning:

“Blocks solved by you” doesn’t mean you get the entire 40 coin block reward when you’re in a pool; this simply means your rig happened to hit the hash that that solved those blocks. You are awarded your share of the work in hashing any given block, just as all the others in the pool are, based on their hashrates.

Some other user with the same hash rate as you may have “solved” more blocks, but got the same number of coins. See my example below (it was when block reward was 80 coins): 9*80 = 720 coins. I received 837.4 coins, but my rig didn’t hit as many “solutions”. Doesn’t matter. That’s the point of being in a pool.

Pools work through a share algorithm, the most common being PPLNS, or “pay per last N shares”, which I think give-me-coins uses.

Solo mining means your rig tries to solve every block before time’s up (1 minute), and submit it before someone else does, in order to get the most coins over time versus pool mining. Luck plays a larger part in solo mining, and is evened out over a much longer period of time/blocks, whereas pool mining evenly distributes the reward based on overall work done on each and every block.

Your 1.4MH/s on that system represents 0.02% of the network hash (~6.8GH/s). That, along with varying difficulty and the “luck factor”, means you might, over a long enough period of time, equal what you’d get from a pool… ;)

It’s already been the big thing for a couple years.

I can’t tell you specifics of what we’re doing with it, but we’ve had an 8x volta 80Gbit nvlink system on order for a couple months now. :drooling_face:

Imagine what 40,000 cuda cores, 5,000 tensor cores, and HBM crazy-fast memory all ganged up in one box can do these days. Distributed systems have been designed to allow several multi-gpu boxes to be connected. That’s the reason ML/DL has taken off so quickly; this kind of raw power was practically unthinkable a mere half dozen years ago, and is making models only dreamed of before workable today. But then we all knew where gpgpu was headed anyway…

I had picked up a book on neural networks twenty years ago, and wondered then just what good that would ever serve in our lifetime. Who knew.

(btw, quantum computing is at the same stage now that nn’s were back then… :))

@jimmy24651

In gihub, any binaries the dev makes are listed in the Releases link at the top. His latest (2 years old this month) includes all the binaries in one zip file rather than individual .exe’s (I’m assuming you’re running windoze…).

If you want to compile, you can either use git to clone the repo (copy locally) or download the zip or tar.gz’d source in the Releases page.

@anema said in GTX 1070ti:

I was thinking 6x 1070ti.

Go big or go home, eh? :)

I’m sure you’re going to use usb risers then. If this is your first build, please consider using 6 to 4 pin molex connectors straight from a modular psu and throw away sata-based connectors. 200W+ cards can draw enough through the pci slot (6 amps) to warm up/melt those sata connectors that are not designed for 24/7 mining gpu’s. Don’t need any fires, right? ;)
