I'm dual mining Ethereum/Sia using Claymore. I've noticed the Sia difficulty has decreased substantially in the last week or two. It's currently ~166TH. I used to get ~3000 Sia/day and am now getting ~4000. Any thoughts about what's going on? Are miners shifting attention somewhere else?

Here you go -

1. Nearly ruined my marriage after I took over the dryer and oven circuit to run miners
2. Heated up my basement to 90 degrees (since then moved miners outside)
3. Ripped up my house having 400A of electric service installed... so I could run more miners
4. Annoyed my neighbors with what sounded to them like jet engines coming from my backyard (have since soundproofed fairly well)
5. Sleepless nights waiting for Bitmain releases and reading up on crypto
6. Nearly lost my day job, too busy focusing on crypto and miners
7. Still waiting to break even!
8. Stopped having people over my house because they freak @ the mini-data center running in my backyard

I ended up ordering 5x Obelisks. Time will tell if that was a good idea or not, who knows. Total came to $12670 with shipping. Sia is an awesome project. I'm a bit worried about Filecoin, I've read all the comments about Sia being better tech and that Filecoin doesn't actually exist yet. But sometimes the winner ends up being the one with the biggest bankroll and highest profile backers. Not sure who that is at this point.

Siacoin was ~$.008 at the time I ordered. If I were to buy Siacoin outright - $12670/.008 = 1,583,750 Sia (roughly)

So the way I figure... the ROI is the $12670 + added risk of product uncertainty + my time & effort setting up/operating + electricity costs.

To that tune, I'd like to be able to mine a minimum of 3,000,000 before Obelisk end of life, which is maybe 6-8 months of mining with 5 of them (at 100Gh/s)? Who knows what the difficulty will be.

It'd be great if the 100Gh/s spec became more like 200Gh/s or higher!



 

I've got 12 mining rigs with 8 cards each, 11 with GTX 1070s and 1 with RX470s (dual mining Eth and Sia with Claymore). I've been hesitant converting them from Windows 10 to SMOS because the overclocking and power control in Windows 10 works so good. And the hash rate is slower in SMOS, ugh. I don't think it's SMOS as much as Ubuntu and the drivers SMOS is based on, Linux just seems to suck. With 8 GTX 1070 rigs in Windows 10 I can get 230+ mhs, including in dual mining mode with Sia with most of my rigs. In SMOS I'm getting ~209-210 Mhs. And this is mostly stock because the overclock settings don't work very well in SMOS. Windows 10 is "fairly" stable, but I have to keep a pretty good eye on. Flashing SMOS to a SSD and changing the email address is wayyy faster the configuring Windows 10.

I did recently convert 9 of my rigs to SMOS (keeping my 3 highest performing rigs in Windows 10), I took the hash rate hit, because SMOS is hands down more stable than Windows 10, for me it's worth it for the stability and easy of use. The ability to edit the configs at the same time and check stats via the web interface is just way easy. With the occasional down time in Windows 10 my guess is it's close to a wash. If I was running just a couple rigs I'd stay with Windows 10... but because I have 12, SMOS makes sense.

I don't think the overclocking/power setting in SMOS work (and maybe not so much SMOS as much as drivers?). The same overclock setting I used in Windows 10 will not work in SMOS on any of the rigs, SMOS freezes/reboots. And the power setting, no luck either. Measuring with Kill A Watt, there's no change with power when I change power settings in SMOS (most of my rigs are consuming a decent more power in SMOS than in Windows 10). If I change from 110w to 80w or any variation of there's no change in the Kill A Watt readings - same darn thing. I don't think the power setting does anything. The overlock setting do something... when I edit, it usually makes things worse, unfortunately. But at least it does something. I don't care so much about the overclock settings... I want the power settings, if could reduce that it'd be great. And again, this is using Claymore.

I also got my order of SRR recently - I have to say it's pretty darn awesome. Even though I'm in the same house as my rigs most of the time, not to have to go to my back deck (my rigs are covered outdoors) and turn off/on my rigs is great. The SRR board has LEDs on it so I know right away if the connection is good between my rig and the board. I have not able able to get the Watchdog to work - so it's manually rebooting so far with me. I run/install WatchDog in Windows 10 via the app and nothing happens. And the SRR Windows 10 app says Watchdog is not installed. Not sure why. I have a Ubuntu box dedicated to Plex/media, I'm probably going to try to install there and see what happens. But again SRR it is pretty darn awesome.

Overall, I'm committed to and happy supporting SMOS. A couple of these issues figured out would be amazing. And for those complaining about support, etc. - it's probably a person in Poland who's doing this in addition to their day job, supporting the community, you can't expect what you might from a large corporation. $2 USD a rig/month is a bargain. I think the team is doing a great job. I look forward to future releases! Would love to be able to mange my SMOS rigs via an Android app!!

 

I have to say I REALLY like SMOS. Cannot wait for overclocking for NVIDIA, will migrate all my GTX 1070 Windows 10 rigs to this. Would also like to get the reboot, SRR controller. And that SMOS based on Ubuntu LTS is probably a good thing.

I have a mix of GTX 1070 (Windows 10, 4 rigs 8 cards each) and RX 570 (SMOS, 1 rig, 8 cards). For my RX 570 rig, I tried Windows 10, ethOS, PIMP, and after painful troubleshooting I couldn't get it working quite right. Either the cards were not all recognized, driver issues, I got the cards working but couldn't overclock. Last resort I tried SMOS - recognized all my RX 570 cards in one go and was hashing with ethermine pool in about 15 minutes. It took me another 1-2 hours to get the overclocking settings right, mainly because my cards were acting funny and I had to set them each individually. No idea why, they're all the same cards (Sapphire Nitro+). I'm using Claymore, ethereum only. I'm only getting ~196 mhs with the 8x Sapphire Nitro+ cards, same as I was getting in Windows 10 (no OC, and running @ 1700 watts!). I tried adjusting the bios timing straps, didn't work. Think there's something with these cards, not thrilled with them.

For my 4 Windows 10 GTX 1070 rigs, stability is OK on 3 of them, but not great, still needs occasional resetting/reboots. Tuned, I'm getting ~240 mhs @ 1200W on each. On one of them stability is terrible, 2-3 times a day I have to restart the miner or the rig. Curious how SMOS would work with GTX 1070, I switched my Windows 10 HD with one I prepped with SMOS for NVIDIA. Same as above, recognized all 8 cards, and was up and mining with ethermine pool in 10 minutes.

@ Power Limit 70 I'm ~209 mhs. This was the same without the Power Limit set, so not sure if it did anything (I didn't measure watts without it set). This is down from the ~240 mhs I was getting in Windows 10 (with overclock settings). With Power Limit 70 I'm @ ~1320 watts. About 120 watts higher than what I was running in Windows 10. I'll likely leave this rig as SMOS because of the instability on Windows 10 even though hash rate is lower and power consumption is higher. It's probably offset from the rig downtime.

Then we just need an Android/iOS app!

In the last few days I set up an rig w/ 8x Sapphire Nitro+ RX 570. I'm pretty disappointed with them. @ stock I get ~24mhs running at nearly 1700 watts. Micron memory. Which is pretty normal, issue is with the overclocking.

I tried Windows 10 first, got them to work using a driver fix but couldn't adjust the memory/core clock settings in Trixx or MSI Afterburner. I also tried modding the bios, no luck, either ended up crashing in Windows 10 or there was no change in the hash rate. So I reverted back to the original bios.

Gave up in Windows 10, tried ethoOS, could not get all the cards to recognize. Tried PIMP, same, issues getting all the cards to recognized. Tried 1 card at time, followed typical troubleshooting steps, motherboard bios settings, risers, etc. No impact.

Then I tried Simple Mining OS, just because I was frustrated I started out with all 8 GPUs, and to my surprise they were all recognized the first time! How nice.

The best I can get now, using the overclocking settings in Simple Mining OS with all 8 cards is ~197mhs running ~1150 watts. Kind of sad. Have a few rigs each running 8x GTX 1070s in Windows 10, have no issues getting ~239mhs @ 1200w.

Here's what I'm using. I ended up having to adjust each one individually, they're all acting different. I could not replicate the ~29 mhs I'm getting on the last card with any of the others. If I run at stock settings hash is same as Windows 10, ~24 mhs @ 1700 watts. I might have to tune my last card down a bit too, is freezing once in awhile.

At this point I'm just tired of messing with it. Maybe it's user error, but I kind of think it has something to do with these cards. Don't have these kinds of issues with my GTX 1070s. I'm going to try my next batch of GTX 1070s in Simple Mining OS, if all goes well I may move my existing Windows 10 rigs to it.

Core/Memory/Mhs
1025 / 1750 / ~23.75 mhs
1050 / 1750 / ~23.75 mhs
1075/1850 / ~25 mhs
1075 / 2175 / ~24 mhs
1075 / 2150 / ~23.75 mhs
1075 / 2150 / ~23.75 mhs
1075 / 2150 / ~23.75 mhs
1130 / 2150 / ~29 mhs

I bought a couple from the Aug./Sept. batch and am feeling like an idiot for not doing enough homework. From reading the thread seems like I'm basically screwed. Any thoughts on strategy at this point? Try to turn around and sell them for as much as I can get as soon as I get them? Use them, take the cost of electricity hit, and hope LTC value increases? Am a newbie. Anybody else in the same boat?
