Hello all,

Long time SimpleMiningOS / PhoenixMiner user here, previously very happy with several 8-GPU rigs (all AMD RX 4xx/5xx).  Recently sold a bunch of rigs and with the various hardware I put together a 12-GPU rig, all Sapphire Nitro RX480 8gb.  I am running into strange behaviors, however, when after many hours of uneventful happy hashing....

• 7 GPUs will drop to 0 Mh/s
• SMos shows 12 GPUs active
• The remaining GPUs start producing incorrect shares
• -minRigSpeed is apparently entirely disobeyed because I can see the rig hashrate (~155 Mh/s)
• Ethermine eventually sends me an email telling me the rig went offline

-pool ssl://us1.ethermine.org:5555 -wal $walletETH.$rigName -minRigSpeed 375 -rmode 2 -gt 64

Clearly watchdog isn't catching this, because it appears that minRigSpeed is being ignored in this situation.  Any ideas?

Honest review of Gunbot:
It's not magic.  It's a tool that does things for you automatically.  When I started, I started with v3.3.3 command line (because that new configuration file system was WAY easier to configure that v3.3.2 and earlier) the market was pretty stable, and I accumulated my license fee back in about 10 days using ~0.5 BTC as capital.

The market has been REALLY difficult to manage lately with BTC pumps, but Gunbot still has been trading opportunities that I would never be able to do on my own.   Since I started, Gunbot has gone through several iterations and versions.  The community is a pretty amazing one - with a lot of helpful people.  Is everyone human, with their own faults?  Yes.  Am I making money?  Yes.  Does it still take effort?  Sure.  The more effort I put into this to learn about Forex-style TA, and stay involved in the crypto new - that really helps.  I'm learning SO much, and that makes this worth even more than the money.

Of course, the above Telegram messages are pretty thrilling...

Mac works, and Chrome is best.  Feel free to message me (http://t.me/culturecrypto) if you want to chat more about buying!

Let's try again.  You can run each trading pair, (BTC-ETH and BTC-LTC are your examples) with different strategies at the same time, yes.  Each trading pair specifies which strategy to use, and you can tune each pair however you like, individually.

As for adding TSSL to STEPGAIN - you now have TSSLSTEPGAIN and STEPGAINTSSL, and you also have BBTSSL, but how do you mean "adding TSSL to STEPGAIN?"   Either use STEPGAIN (which uses defined steps and a trendwatcher) or TSSL, which uses trailing stop increments.  If I'm still not answering your question, maybe try rephrasing it.

As I've re-read your question - one more thought.  There was a time (in Beta, before release) where TSSL was not available as an independent strategy, and was in the configurations of other strategies for testing.  It is no longer like that.

I agree with dobcrypto - people like to hate on Windows, but either works just fine.  Get a service that's cheap... and if shopping for a VPS gets too painful, come talk to me on telegram @culturecrypto

Yes, you can create multiple market-specific setups, and switch between them.  You can also run as many coins as your exchange offers, not just ETH or just LTC.


And  yes, the current release has 36 strategies that comprise many combinations, such as buying with STEPGAIN, and selling with TSSL ("STEPGAINTSSL") etc.

So I thought that when Claymore introduced the -minspeed variable, that was pretty cool!  It's kind of like a low hashrate watchdog, right??

So I set it, with a decent margin, so that if a GPU was way out of whack it would reboot and all is good.... but I'm telling the story backwards... let me rewind.


This morning, the DAG update happened.  Strangely, one of my rigs kept on rebooting.  Like, LOTS of reboots....Not being in the same room, with most feedback from EthMan, nothing was super obvious.  Each GPU's hashrate decreased just a bit as expected, but none of them dropping to zero, or anything typically suspicious.  I was thinking that MAYBE the DAG got heinous enough to be difficult with the strap timings.  This rig has RX 580 Pulses, and I haven't been successful getting tight straps on it (like, no Ubermix or whatever) but it's "ok" - but maybe this latest DAG was just too much.

I tried to downclock the memory... -30, -60, -100... nothing!  Maybe, I'm thinking, maybe I finally install that bobo driver and see if that helps? 

So I finally got to watch the console ... weird, no GPUs are misbehaving at ALL.  WTF?

FIVE MINUTES (this is a magic number) and the error appeared.  It pushed that one rig down under the -minspeed threshold.   That rig rebooted 73 times today.  SMH.

Anyhow, changed the -minspeed to a now-safer number.  Ta f'ing Da.

Driver mixing is not required as of 17.7.1

17.7.1 is the most recent driver that works well with Claymore and does not require any mixing to use with up to 8 GPUs

17.7.2 will need an update from Claymore, as currently it doesn't report temperature or fan speed, so don't bother with this one

Both require the pixel clock patcher for bios signature if using modified BIOS

DAG related hash rate slow down is not yet fixed with either of these drivers.

install amd driver 17.7.1 (no mixed drivers) then apply the pixelclockpatcher (renamed to only sign the driver), then reboot. 

You need to use the PixelClockPatcher (to sign the bios), but other than that, yes - the driver is compatible with bios mods, and also works with up to 8 GPUs without "mixing."

I tried it on my rig with BIOS-coded clocking (not setting clocks via Claymore, wattman, or anything else) and it performs equally to 16.9.2, excepting the above mentioned issue with fan speed and temperatures registering in Claymore.

When I say equally, I mean Sapphire RX 480 Nitro+ OC's running at 27.8-28.1 Mh/s ETH, 800-820 Mh/s DCR  (DCRI 29) which is what they were running with this new epoch 136(2.06GB).

That really is strange. My rigs are producing more shares per hour, per GPU, than that - at 28.8Mh/s. Let's go along with this and assume it's NOT a Photoshop job. Maybe a super fast hash, lots of bad incorrect shares, still don't understand how it would stay alive for 150 hours. Doesn't really matter of it's not producing good shares.

How about last night's DAG?  It took an average of .3 Mh/s from all 24 of my cards - both RX 480 and RX 580 cards.

That seems to have done it - thank you! 

Is it true that a new worker can be created simply by mining with a new worker name, or must the worker-name be created first?

Sorry for the support question - but I have four workers running now, only 3 are shown on the dashboard as if the 4th does not exist.  It's communicating with the pool no problem, shares accepted, etc. 

I have 8 workers set up in my account, (only 4 operating right now) and on the worker page only 3 are showing as orange, and with "active" flag.  Any ideas?  They are all using the same Claymore configuration...

Awesome, and thank you for that insight.  I saw your OP update about PSUs out of stock, and have sourced two separately in anticipation of your return.

I'm currently watching a 6-GPU rig pull 1090w at the wall (248v)... I'm looking to push this to an 8-GPU rig, and then replicate for a total of 3 mobos and 24 GPUs.  If I assume the non-GPU components take 150w per rig, that takes me to approximately 4250w (at the wall). I have external cooling available powered outside of this PSU, so assuming temperatures remain good.  (For example, my GPUs run at 60º +/- 3º all day long.

Do we think one of these DPS-4KW units will safely handle 4250w at the wall, continuously?

Did you make any progress on this?  I'm curious about TOLUD as well, though I have been mining successfully on this mobo with 6 Sapphire RX480 Nitro+ OC 8g cards.  Also 4gb memory, though I'm using a Core i3 cpu.  Perhaps that's your limitation?

I'm trying to work through the 7 gpu process, and will put more into it tonight.
