I currently have Sha at 750 ant scrypt at 850.

I think one chip can't work on two different freq.
As I remember for Scrypt core used part of BTC core, so maybe these two cores can't work on different freqs.
(but not sure)
Maybe for whole chip used first BTC freq. and second is ignored..

Can somebody confirm is it true or not ?

They simply, can not run two different frequencies at the same time.
One is simply over riding the other - evidently un-noticeably.
There is only 1 clock generator and bus for all chips on the card so.....

Placebo   Running at separate clocks will make you feel better...   It could also cure cancer.

Sounds legit... mine at 750/750 seem to be the same as any other combo starting sha at 750... changing to 800 causes nonce errors again in mine... shame.

GS needs to make a firmware update for all of these...

Just heard the news about the upgraded firmware for the 'exclusive' Lighteningasic's Controller.
Says it solved the problem with miners quitting out of the blue. No more manual intervention.
Where do get one of these miracle Controllers from? I assume Lighteningasic?
Link please?
Tanks

Uhm.  Like I said, schedule a reboot every time one hangs or hourly just like the new controller box...

How does one set this up? Using what program or macro program?
I'd love to have something to 'monitor' and restart my miners if one or all of them go down at the same time.....

^^ This... they require a USB power cycle... most reboots never cut power to the device.

It is a crude way of resetting the USB ports. That's all... Unworkable for my needs...
I'm looking into macro's...cheaper and easier to manage and it will do exactly what I want when I want it to do it.
Keep It Simple...eh?

I've got a question regarding hardware errors on a Gridseed device....

I've got 1 miner in particular which seems to throw out way more HW errors than the other 9.  Typically the others may throw out 1 HW error from time to time...but this one averages 1 HW error each 1.5hrs or so.

I've tried the following:

1. Swap USB cable
2. Swap power cable
3. Swap USB port
4. Swaped which PSU its connected to

Regardless of what I do it seems this one miner is destined (or perhaps just a bit defective) and will continue to toss out HW errors.

I'm using freq=800 as it seems to be a balance between keeping 1 one from throwing errors and the other ones from "under" performing because I can't tune each miner individually.

My question is not what could be wrong, because I think this is just a crappy unit...but is it bad to keep using this miner and having it throw out HW errors?  I presume it just means this one miner will likely die well before the others?

[ghur]

I've tried searching this, but I couldn't quite find this on my own.

What are the power requirements from the USB hub in single mode?
Would a powered USB hub with 500mA per port suffice?

So long as the overall hub power is greater than 100mA per port it shouldn't be an issue per the gridseed spec sheet.

Thank you. I know what to look for now

The frequency of HW error is too low to worry about. Most likely there is nothing wrong with the unit itself.

Hey all,

This is my first post here. This thread (and a few others) have been really helpful to me getting 24 gridseeds running on windows 8.1. I wanted to say thanks to all contributing. I have also been searching for a decent #gridseed irc. Not much luck so far, the rooms are small, quiet and/or specific to a store that sells gridseeds. So we started #gridseedmining on freenode.net to share info, specs, builds, tips tricks and workarounds. We'll see if it picks up any popularity.

Anyways, thanks again. Hope to see you all in the channel. #gridseedmining FTW!

Im still looking for a way to get Windows to see these devices. I downloaded the recomended cpuminer from page 1, but the devices don't show up in the device manager under windows. Are there any tricks to getting Windows to recognize these as USB devices?

Are you using a USB cable that came with the unit or one you had already?

I have discovered I have a handful of USB cables that fit these, but do not power them up AT ALL. Also, zoomhash saw fit to ship mine with a micro USB instead of a mini USB, so I had to use one I already owned.

When you plug it in, does the green light come on and Windows pops up telling you a device was detected? Or you get nothing? If it does pop up... zadig needs to be used per the OP instructions.

I went with cgminer 3.7.2 for gridseed listed here:
http://cryptomining-blog.com/1262-download-cgminer-3-7-2-for-windows-scrypt-mining-on-gridseed-5-chip-gc3355-asics/

and followed the instructions to replace the drivers. There are some quirks, though, as others have mentioned. You have to plug in or enable the miners AFTER you start cgminer, and occasionally the quit returning shares and you have to start the miner over. I'm going to try bfgminer too.

[CartmanSPC]

I have had success using Ubuntu server and dtbartle cgminer. No hang ups with the USB ports with 20 miners.

...too bad actually as I miss using cgwatcher but it's been solid.

I am going to try volder's workaround tonight, because i want to use cgwatcher too.

Has anyone been running their GridSeed Farm 24/7 stably WITHOUT ANY INTERVENTION WHATSOEVER?

I have a 10 year old Dell Pentium 4. Put Ubuntu 13.4.4 32 bit on it. Did the 5A.1 instructions from here:
https://bitcointalk.org/index.php?topic=494625.msg5448813#msg5448813

Using cpuminer (one screen for each miner), I have been running 10 all weekend without a problem. I tried a Rasp Pi, but that promptly crashed after 2 hours. So I went back to ubuntu. I'm getting 10 more GS in a week or so. Hopefully I can get the Pi to work, or there will be 20 on the ubuntu.

I would take it apart and make sure a wire did not get stuck between the chip and the heatsink. When I have time, I will do that for all the miners, but if I had one problem miner, that would be the first thing I check.

Thanks but I and many others have gone that long without a problem.
Let us know when you're running 24/7, 7 days a week for a couple weeks, then I'll raise an eyebrow
Again, thanks but...no bananas!
