Guys I am running 6 Gridseeds, 5 of the Volt OC, however, the strangest this is happening, they all run fine, but periodically they ALL have a chain of nonce errors at the same time. Then they go back to normal and so on. Both OC and non Volt OC get the errors at the same time.
Any ideas on where to start looking?
Have you checked the volt mod thread? There may be some answers there. Did you perform the 5V USB fan mod as well? Is your USB power supply still adequate to handle the load? How about your main 12V power supply? Still adequate? Any other programs running simultaneously on your PC that are communicating via the net at the same time? I've recently quit running any wallets, especially the ones that are mining, at the same time because they were interfering with send receive comms' of cpuminer. Just some ideas. Hope they help. Good luck! |

Thanks!
Did not do the Fan Mod. Just moved some to another USB hub to check.

Can anyone who knows what their doing help me out here?
I'm still fairly green where commands go.
In cpuminer 1.0b, I see the command for setting each pod to it's own fixed frequency but I don't understand what DEV and F or n stand for or how to alter the command line.
-f, --gc3355-freq=DEV0:F0,DEV1:F1,...,DEVn:Fn
How do I write it into the string? Or, what do I change the string to?
Here's an example of the current command line I'm using:
minerdoc --freq=1175 --gc3355=\\.\com2,\\.\com4,\\.\com5,\\.\com6 --gc3355-autotune --url=stratum+tcp://xxxxx.com:3488 --userpass=xxxx.x:xxxx
It sets the whole smashes freq to 1175 then sets about auto tuning.
So how do I change the string to run individual frequencies for each pod? Not each chip but each 5 chip pod.
I don't understand what -f is saying.
Thanks!

You will want to use a separate instance of cpuminer to run your Blade. A Blade uses roughly 150 watts so you will need a PSU that can deliver that. Is your Blade coming with power cables? I suggest the heavy PCIe cables made by Cabez for the Blade. They are simple and easy to run. Here is a sample argument that I use. 838 seems to be the sweetspot frequency for the Blades. minerd.exe --freq=838 --debug --gc3355=\\.\COM6,\\.\COM7 --gc3355-chips=40 --url=poolandporthere --userpass=usernamehere:passwordhere
pause This is to run the two Blades I have. Make sure you pay attention to which COM ports it installs on. Then put your COMs in there. Then everything should run well. Here is my review on the Blades. http://www.cryptocoinsnews.com/news/5-2-mhs-scrypt-miner-review-gridseed-blade/2014/05/08I hope this helps. Happy Mining.  I have a blade on the way. dhl should have it to me by monday or tues.
While I run the 5 chip units as many as 30 using cpuminer at freq 850 I can not seem to find a thread just for the blades…
What power supply? can I set it up with my 5 chip gridseeds using a com port and freq 850 on the same fork of cpuminer?
Is there a blade setup thread? I just spent 30 minutes reading this thread and can't seem to see simple setup for the blades.

Hi Phil, From reading everything here and running the autotune feature in cpuminer I hit 838 as the best. No errors and stable. Here are the best set of cables I have used. 16awg base cables for blades Cablez made them for me. They handle the power without getting hot like the thinner cables. Here is where you can get a hold of him if you decide to. https://bitcointalk.org/index.php?topic=74397.0You can let him know you want the cables like I got. I got 14" in length and that was perfect for my setup. You will want to use a separate instance of cpuminer to run your Blade.

Okay, let me put it a different way....
-f, --gc3355-freq=DEV0:F0,DEV1:F1,...,DEVn:Fn
Okay, so since it seems that I cannot use com in the command line to identify which DEV (device) I want to set to fixed freq (F), how do I find out what the DEVice number of each pod is?
There has to be a command for that, right?
All I need then it to find that out and I think I'll be good to go.
Anyone?

Try using a json file, example create a file called "gridseed.json". Use sample below for a start: {
"gc3355" : [
"\\\\.\\COM2",
"\\\\.\\COM4",
"\\\\.\\COM5",
"\\\\.\\COM6"
],
"gc3355-freq" : [
"\\\\.\\COM2:875:0", "\\\\.\\COM2:875:1", "\\\\.\\COM2:850:2", "\\\\.\\COM2:850:3", "\\\\.\\COM2:850:4",
"\\\\.\\COM4:875:0", "\\\\.\\COM4:875:1", "\\\\.\\COM4:875:2", "\\\\.\\COM4:850:3", "\\\\.\\COM4:850:4"
"\\\\.\\COM5:875:0", "\\\\.\\COM5:875:1", "\\\\.\\COM5:850:2", "\\\\.\\COM5:850:3", "\\\\.\\COM5:850:4",
"\\\\.\\COM6:875:0", "\\\\.\\COM6:875:1", "\\\\.\\COM6:875:2", "\\\\.\\COM6:850:3", "\\\\.\\COM6:850:4"
],
"pools" : [
{
"url" : "stratum+tcp://Main_Mining_Pool_URL",
"user" : "USER_ID",
"pass" : "PASSWORD"
},
{
"url" : "stratum+tcp://Failover_Pool",
"user" : "USER_ID",
"pass" : "PASSWORD"
}
]
}
Above configuration is for after you've done autotuning. Replace the frequency for each individual chip. When running the cpuminer, GSD 0 > COM2, GSD 1 > COM4... and so on. To run with json file, execute: minerd-gc3355.exe -c gridseed.json |

I see a newish commit for Sandor's cpuminer allows you to reference Gridseeds by serial rather than COM assignment. How do you find out the serial for each Gridseed? Thanks in advance.

I just noticed something very interesting that may be a key bug in the latest and previous versions of cpuminer.
When I was testing one of my 5 chip miners.
I usually run 26 miners at the same time. Hardware errors are minimal and sometimes they get ridiculously high right after I fire up cpuminer then settle out.
I've also noticed very high HW error counts after a 24 hour run after autotune has supposedly set all the pods to their optimal clock speeds.
I don't think I'm getting as much performance out of the set as I could.
The reason being, that when I was running just 20 of the miners, *6 of them were disconnected for cleaning and to change the 5V Fan power feed from USB to the 12V regulator's 5V output rail), after plugging in just one of them for testing then running the whole batch of 21 miners, I notice that at the clock setting of 1175, virtually all of them stay at 0 HW errors! Maybe one or two of them hit 1 HW error but that's it!
When running just 20 of them, HW errors go out the roof at first then seem to settle out after several minutes but wow! I mean HW errors go crazy high! Like 20 to 30 inside of a minute or two!
Again, when I plug in pod number 21 and start the mining program again, HW errors go away almost completely. I mean 19 out of 21 stay at ZERO HW error!
I am wondering why? I mean, is it my USB hubs acting up? Doesn't seem like that would be the case but what else could be reacting to the number of USB ports running but the USB drivers themselves?
Perhaps this is caused by a bug in the way cpuminer handles the USB ports, adding up and averaging all the pods hash counts....
I don't know.
Time for an expert to look into this? Sandor111? What do you think it may be?
Thanks ahead of time for any assistance or ideas anyone may have.

I think serial numbers may only be supported in Linux. Please correct me if im wrong |

Autotune does not set optimal clock speeds in all cores of all Gridseeds. You've got to take the values given from autotune and lower/raise them a bit. Not all cores from my devices were set to their optimal speeds. Autotune is VERY, very good, but not perfect. As for the rest I don't know. Don't have as many Gridseeds as you, and no problems here. |

Not all cores from my devices were set to their optimal speeds. Autotune is VERY, very good, but not perfect. As for the rest I don't know. Don't have as many Gridseeds as you, and no problems here. Right, I realize that, but I beg to differ. That is exactly what auto-tune IS supposed to accomplish. Optimum clock rates for each pod. Then one is supposed to 'rather left with' having to record each setting where you don't see more HW errors accumulating and set each pod manually to that specified frequency. Otherwise autotune is a waste of time IMO. I just found the sweet spot for ALL of my pods, at least where 98% of them are still at 0 HW errors after an hour now, where before they would be up over 30 or even 50...some out the roof! Anyway, after re-modding 6 of my original pods for 5V regulated power feed from the 12V rail, I tested each one separately and found that most of them really like running at 1163MHz! The chips settle at 492MHs to 498MHs. Pool side sees that as the same or more and some of them are peaking at over 800MHs..I"m looking at one right now that's been hovering at 790 for several minutes now...Pool side of course...My pool side total hash rate is hovering at over 14500KHs! Yeah baby! Before it would hover at around 10 to 12MHs...oops, it just hit 15211KHs  . I see it hit over 17MHs a lot too! I want ZERO HW errors so those otherwise wasted hashes get put to good use = mo-coin! One thing that still bugs me though is not being able to set the whole set of chips (5) to one fixed frequency. I see how one can use com in the command line to set each chip to it's own fixed frequency, so why is there not a similar com option to set all 5 together? It's simple enough to do but of course if that were totally true, I would have done it already, wouldn't I? Anyway, you get the point. I just wanna set each pod to it's own hash rate and that's that. They are doing wonderfully at 1163MHz though, so I might just leave it there. Still, I'd like to know how it's done....Just in case Woofy Pea Ess, just in case someone doesn't believe my claims....have a looksee  |
