Topic: OLD: BFGMiner 3.10.0: modular ASIC+FPGA, GBT+Strtm, RPC, Mac/Lnx/W64, AntU1, DRB - page 32. (Read 1193208 times)

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.

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

Thank you!

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.

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 ?

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

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)

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:


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:

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?

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.

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

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

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 ...

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

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.

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.

A post from elsewhere:
"""We have not switched from "Scrypt" to "Adaptive-N-Factor Scrypt" (aka supposedly ASIC resistant, as if thats a huge problem for scrypt coins right now) for several very good reasons, all outlined by our development team here: https://kittehcoin.info/forums/meow-technical-discussion/does-kitteh-have-this-same-doge-mining-problem/msg2388/#msg2388; Majsta makes some excellent points as well."""

Any one else no longer able to use bfgminer on scrypt GPU on alt pools ?
All of a sudden, any pool address nothing works here on any of 6 machines.. what changed other than kgw and n factor ?
It was working fine a week ago. I noticed the pools were disconnected from stratum, on reboot nothing works, everywhere.
bfgminer -S opencl:auto --scrypt -o stratum+tcp://altcoinpool.org:3341 -u xxx.xxx -p x -I 9,9,9

Ant / usb / gpu miners on Bitminter still works fine.

Is nwools taking care of scrypt now ?

This thread is NOT the place for this question - try the Hardware section of the forum.

Hey Guys newbie here still. My powered usb hub I bought was not working right when I plugged in some of my BE. I had an antminer that was not running at the 1.6 it was advertised as. per a suggestion on the site my usb hub might not be putting enough power I looked at the website for the company that made it and right there on the page it said it is not for asic mining. so I returned it and the only beefed up powered usb port they had was a 28 port 4 amp. My question is will I be wasting tons of ports on this beast? I spent like $90 bucks on it. I do plan on building up my mining operation but not all at once just a miner here and there.

request :

After 2-4 days, on my BFL ... i have somes unexpected queue error (a chip does a loop).
BFGminer view this.

In my computer, i have created a "planned job" to kill BFGMiner task every 6 hours and restart after 1 min to avoid this.
But, in BFGMiner, you can add this feature ?

Like :
- if unexpected queue error from 1 chip append, wait 10-20 second
- if always append
- kill USB probe
- restart USB probe after 5 second
- continu job like usual.

Thanks  

Note : i don't touch anything on my setup (i don't unplug BFL or restart PC) ... kill BFGminer and restart solve the problem in all situation.
I have a BFL 12GH/s and a BES 333MH/s.
