Any multipool that is preferred?

I tried Waffle and Middle which were "OK" and now HashCows, but even with my LA6M crappy performance (Somehow are unable to get hashes over 2MH/s total), i got only 0.00096357 BTC for 12 hours.. Should be around 0.024-0.030? Something is not right, still no idea what..

I'll try to up the hashes next week when i have the original USB hub and gridseed controller in.. Hope i get near 6MH/s total then..

(I do get near 4MH/s when plugging miners in one by one and let them settle in between. However, it reboots not long afterwards.. When it comes back, i get maybe 2MH/s max, and some won't start hashing..)

Could there be another reason besides the controller FW (RC1) and usb hub? Replace USB cables?

How many controllers are you using? And, are they LightningASIC versions or the generic Gridseed version? If Gridseed, did you upgrade to 2.0.2? These answers might help in figuring this out.

I am using them on middlecoin. Its working out great.[/b]

What rate are you getting on Middlecoin at what miner speed? How often does your controller reset?

between 5-6 mh(share estimation) from 19 on one controller. you have to factor in that these submit less shares than a gpu rig so there is some variance. I am probably hashing at around 6 MH actual rate.

Running at 800-900 mhz havent decided where i wanna leave it yet.

Finally had most of the miners hashing at the claimed speed.. (It was at 2,8MH/s and picking up speed)
Controller reboot.. Now it fails to hash on some miners..

Hopefully, the new FW will no longer need reboots and/or the reboot can be disabled yourself.
No need to have Jack or his tech login to disable this.

Now at 1,66Mhs with 18! units (3 don't work most of the time, so i'm really counting 15..

Curious if the original gridseed controller is more stable or at least give more constant speed..

I'll know somewhere next week..

You guys realize the dashboard isnt measuring hashrate. Rather estimating it based on shares submitted.

These units are most likely all hashing at their own constant rate. (based on chip quality solders and ineffeciences)

I am using them on middlecoin. Its working out great.

I am finding that on pools and P2Pools where the share difficulty is high, the miners cant all get shares accepted before the controller decides to reboot everything. You are forced to use a vardiff or low difficulty pool with them. I find it quite irritating.

What's the best way to test an individual miner?
Connect 1 to the controller instead of the hub and wait a few minutes?

Hub, assuming you have put all the right information into the controller fields. I got one working (at 600), then two, then plugged in all the rest. If any do not work, it should not be hard to find out which one(s) is(are) not working.

Would be great if some more advanced test (that FORCES it to try to hash at the max speed) were available, so you instantly know which one works and which not..

Get them working at 600. As soon as that is stable, up the speed: 800, 850, and then 900.

The ones that do connect seem to hash, etc and it see things happening in the console.. But, nothing is seen in the pool, so it doesn't seem to work.

Hi,

Tested the individual miners from unit 1 (LA3M), all hash. But, if all connected, some don't.. Is this USB-hub related? I have a Delock USB 2.0 External Hub 10 port (p/n 87468), 5V / 3,5A.
Could it be something wrong with the individual cables? Tested all miners with a cable i knew worked..

Unit 2 has 5! miners that don't hash, so 15 working out of 20.. Something is really wrong with quality control..

I try the cables later tonight, if it's the hub i'll sell these and buy new ones.

Which brands are working?

Thanks,

Andre

i did builded for raspi cpuminer2.3.2(https://github.com/gridseed/usb-miner)
miner is good runing
but hashrate 0.00 why? Huh

http://i.imgur.com/74skQjJ.jpg

Seems like you are hashing, but have 90% rejected (11% accepted).

There was some discussion about the windows cpuminer version not calculating hash rates. If it is the same software, it probably does not calculate it either.

thanks for your reply
my options ->./minerd -G /dev/ttyACM0, /dev/ttyACM1,...../dev/ttyACM9 -F 850 -o [POOL] -O [worker0:pass, worker2:pass,...worker9:pass]
i'm wrong?
and what do you recommend of cpuminer?

can somebody ... compile windows binary for cpu miner .... to use no BTC cores ....
...

also is there any firmware image of the lightningasic build ... I got a bricked controller ....

My 10 linked to the controller reboot once every hour-ish, this is something Jack is testing the new firmware on which is soon to be released.

Funnily enough they seem to be getting better by the day, speeds are slightly up and much more stable on my pool.

I am looking at buying two more mining hubs to make 12 and hopefully run those through the the PSU's and one controller.

Thank god for early adopters! I'll be back in 6 months when the price halves and bugs are worked out.

Whats the magic number of Gridseeds we should be running on the LightningAsic controllers?

Apparently 10 will cause crashes and reboots etc. I am thinking of only running 6 or 7 and then running 3 as single miners for better stability

Idk im running 19 on one tp-link and it restarts nearly every 10 minutes :/

One of my tp-links was DOA Sad

Well if 10 on one gives crashes every 6 hrs or so I wonder what under 10 will do.

I'm gonna run some tests and try find the sweet spot

If anyone else wants to give it a shot that would be great to compare

Anyone know if we can expect to see fan control in the software/firmware in the future? or if the fans are hard wired?

I really would like to lower the speed, I don't see that I need all this for only mining LTC and I'd like to keep the setup close to my living space.

Same here. They are running fullspeed, generating a lot of wind and noise. However the heatsink doesn't seem to get even warm in scrypt mode.

poopypants compile this one:

https://github.com/gridseed/usb-miner/blob/master/software/cpuminer/

It doesn't send the commands to activate the BTC cores, so you'll be fine with it in LTC only mode.

The miners work pretty interesting however. They used a version of cgminer which already had scrypt support removed. BTC only mode runs with cgminer. LTC only mode with cpuminer. To get dual mode you have to run them side by side - cgminer handles BTC like normal, cpuminer only polls work to do from the pools then sends it in upd packets to cgminer which gives it to the LTC cores. cgminer then sends the results back in upd packets to cpuminer...

Does anyone have a link to a precompiled Windows package for this? Thx.
