OLD: BFGMiner 3.10.0: modular ASIC+FPGA, GBT+Strtm, RPC, Mac/Lnx/W64, AntU1, DRB

[TRN1062]

I have a question maybe someone on here can help me with. I am running 9 Antminers all on BFGminer 3.10 on Eligius. Currently I have them running on two different computers because some seem to handle overclocking better than others. Is it possible to run more than one instance of BFGminer on the same computer and specify certain Antminers for each instance and set the clocking at different speeds for each instance of the miner?

Please let me know.

It's definitely possible - you'd need to set the ports correctly on each bfgminer that you run, but it definitely will work, just take a bit of working out which port the good/bad antminers are on, and then writing a startup script for each one with the appropriate settings.  MultiMiner runs multiple bfgminers (to allow it to mine scrypt/sha, and indeed to mine different coins on different GPUs, etc) without issue, so starting it 'manually' shouldn't be a problem providing you specify the ports on each instance.

Are you actually running the code from git?
That being said, I didn't test this yet either... but it's so simple I'd be surprised by a bug.

No, I'm running the 3.10 x86 binaries. Just looking on git to get behind the --set-device syntax. And naturally assumed my syntax is wrong.
Should have looked at git history <.<

Just a re on this: I built from git today, and the HFA clock setting (not surprisingly) works like intended

Hi all.  I'm seeing a high number of HW errors on my GPUs:

I thought it might be power related, so I upgraded to a 1000W power supply, but am still seeing them.

Machine is open-rack, with (2) R9 270xs and an old 5770.

The miner is --balance across 3 pools.

Any ideas?

Oh, temps are below 80C, not sure why that isn't showing.  Command line is:

./bfgminer -S opencl:auto --gpu-fan 100 --auto-gpu --intensity 19,19,19 --temp-overheat 90 --temp-cutoff 100 --temp-target 80 --scrypt --balance -o ...

You generally need to specify --thread-concurrency arguments that are specific to each card platform and model:

https://litecoin.info/Mining_hardware_comparison#AMD_.28ATI.29

Unless you specify the correct value you will get high HW rates.

[Cassey]

Ok - thanks.  Just tried turning the intensity down to 18 on those two cards, but will try that next if the intensity change doesn't fix it.

Ok so its possible can anyone tell me how I can do this? How can I manually set which ports mine on each instance of the miner? I know if I can select what ports start on which miner I can set the clock speeds for each miner instance that is running but how can I select or set the ports?

The actual command specified will depend if you're on Windows or Linux as the way the ports are addressed is different.

For instance, on my Windows miner, my three ant miners appear as COM14, COM5 and COM6, so my multiminer startup script looks like this:

Code:

--set-device antminer:clock=x0881 --scan noauto -o eu-stratum.btcguild.com:3333 -u [USER] -p [PASSWORD] -S antminer:\\.\COM14 -d antminer@\\.\COM14 -S antminer:\\.\COM5 -d antminer@\\.\COM5 -S antminer:\\.\COM6 -d antminer@\\.\COM6 

If you find out the port addresses for your miners, you should be able to run them using a similar command to above, with appropriate clock settings on each with the first argument.

You'd have two commands like this, so for instance, if your "slow" ones are COM 1, 2 and 3, and your fast ones are COM 4,5 and 6:

Code:

--set-device antminer:clock=x0781 --scan noauto -o eu-stratum.btcguild.com:3333 -u [USER] -p [PASSWORD] -S antminer:\\.\COM1 -d antminer@\\.\COM1 -S antminer:\\.\COM2 -d antminer@\\.\COM2 -S antminer:\\.\COM3 -d antminer@\\.\COM3

--set-device antminer:clock=x0981 --scan noauto -o eu-stratum.btcguild.com:3333 -u [USER] -p [PASSWORD] -S antminer:\\.\COM4 -d antminer@\\.\COM4 -S antminer:\\.\COM5 -d antminer@\\.\COM5 -S antminer:\\.\COM6 -d antminer@\\.\COM6 

[Cassey]

Ok - thanks.  Just tried turning the intensity down to 18 on those two cards, but will try that next if the intensity change doesn't fix it.

I'm happy to report that the hardware errors have virtually disappeared with an intensity of 18 - they are now below 0.5%  (11 out of 2807 Accepts)

My GPU VM isn't working lately; does anyone have a GPU mining rig I can do some testing on via SSH?

[examiner]

I Know that bfgminer is not intended to be used as scrypt miner, but it has scrypt support. I need to use it as scrypt-proxy for its proxy capabilites. It's possible to do so? And if yes, how ?

Ok Thanks a lot for that. unfortunately coding and programing are not my strong suits.

on a side note I am running these on Windows 7 and I have a slight dilemma every time the ants are unplugged and re-plugged they change their port numbers I am now on com ports 115+ Id there any way to get rid of the old ghost units so I can reuse the lower port numbers? I've tried usbdeview to remove the old devices but still the com ports show as used and unavailable. I know this is a bit off topic but I really don't know where else to ask.

My GPU VM isn't working lately; does anyone have a GPU mining rig I can do some testing on via SSH?

mining with a bf, 12 bitfurys and drillbit on the pc. the GPU just sitting there so yeah can help if needed

[mfread]

Thanks Freddy (and everyone else that has chipped in to assist).

Good news. I received the replacement ASICminer from the eBay seller today. Plugged it into my laptop USB 2.0 port, fired up BFGminer, and it ran like a charm. Hovers around 350 MH/s.

Even after 2 hours of running (no fan) it still is around 350 MH/s, and only 0.84% HW errors. See screenshot below.

I do like happy endings

Cheers all.

@mfread

You have enuf info now "to be aware" rest is learning, a 12v USB hub is a 3.0 hub.

All USB 1.0 - 1.1 - 2.0 hubs are 5v supplies.

You cannot have USB 3.0 on the machine if it is a intel sandybridge or lower, 3.0 is enabled in Ivy bridge and up only.
AMD I have no clue.
Some boards used a custom chip to enable 3.0, before the new CPU's had it built in.

Lot to learn, keep it up.

================

On BFGminer suddenly my string command
bfgminer -S opencl:auto --scrypt -o stratum+tcp://hashfields.com:3333 -u freddyfarnsworth.HFAsr2 -p x -I 9,9,9 that is for GPU only on alt pools

NO longer works ?? cpuminer still works, nothing changed in the string, is the new cloudflare the pools are using interfering with BFGminer scrypt mining,
Bitminter asic string still works, Not the alt pools tho, I mean All the pools. Started last night ??

Anyone know what is up, is it just me ?

[OleOle]

Glad it's working out for you Mark.

Now, if you've still got that "overclocked" Erupter, grab your favourite hammer, your camera and let's see a quick vid of its destruction

Alas, I'm thinking you've returned it as requested by the seller so he can try to scam someone else to facilitate the refund

Hopefully you find the Antminer as easy with BFG when it arrives.

Cheers.

[mfread]

Thanks OleOle.

I would of loved to video me hammering the cr@p out of the troublesome erupter as it cause me quite a bit of grief But then I would of been out A$40 and no erupter. So commonsense prevailed and the hope the seller would be honourable enough to either refund or supply another (non-overclocked) erupter. So after spending A$12 in registered post (so the seller would have to sign for it and not claim he never received it in the post), I received a replacement (which as we know works like a charm).

However, the seller had the nerve to tell me this (in green below):

Me to Seller:

Hi Bryce.

Have tried 2 externally powered USB 2.0 4-port hubs. Both yield a very high HW rate. Got to > 90% HW error within 5 mins.

Have tried my other laptop USB ports. All yeild very high HW rates. Got to > 90% HW error within 5 mins.

Have turned on the room air conditioner so room temp dropped to 15C *and* placed a 12v PSU fan directly in front of the ASIC device. I was able to run bfgminer against it for a few hours, but the ASIC only gave me between 40 and 90 MH/s.

People on various forums have told me they've simply installed drivers then plugged in the ASIC (not fan whatsoever) and have them running at 334 MH/s at normal room temperature during the Sydney summer without any dramas with a HW error rate < 1%.

Clearly your device is stuffed as you've had it overclocked for a while. I don't like being duped. If this was an honest mistake then I'd like you to make amends.

If you still have more in stock I'm happy to post this one back to you and receive another one that hasn't been overclocked.

If you can't do this then I'd like a refund.

I have attached bfgminer screen shots and CMD file to exec bfgminer under windows 7 x86.

Thanks,
Mark

Seller to Me:

HI, I am sorry to hear that the device seems to not be working, I have non overclocked in stock and I am able to send one out if your current one is returned, can you please confirm your address for me

Seller to Me:

hi, I’ve received the package today, I have now posted out your requested miner, I’ve also had time to test the one you sent back in a 33 degree room and it’s running perfectly without a fan or any cooling

Me to Seller

So I am totally baffled as to why it didn't work properly:

- in any of the 3 USB 2.0 ports on my 2009 celeron laptop
- in a 12v powered 4-port USB 2.0 hub connected to my laptop
- in a 1 year old desktop quad-core with USB 2.0 port on the front (I couldn't access the back USB ports to test)
- in a custom built quad-core mining rig (USB 2.0 on the back of the motherboard)

I'll let you know how the replacement one works out.

Rgds,
Mark

As you succinctly say OleOle, I hope the seller doesn't try and resell the overclocked erupter to some other poor unfortunate soul (this is the reason why I'm documenting the salient facts here in this thread for others to see).

Cheers all.

Mark

[JBT]

although that erupter will run without a fan (hot as hell) you should put a fan on it(them)

[HellDiverUK]

If you've already got the replacement, then why is it a concern if the 'faulty' one is working for the seller?  He can stick it up his ass for all it matters.
