[GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning

[guyver]

what is the story 3 per pc?

That's what beastlymac said but it's not the case, I'm running 5 without issue (other then them stopping once in a while).

this was an issue with the old cpuminer, I could only get 3 gridseeds to mine. but this is not an issue with the new cpuminer complied by the guys at cryptomining-blog.com.
get 10 gridseeds running for an hour now on windows 7

I'm running around 20 devices on Windows 7 with the new cpuminer binary.

Works fine ... but it lakes in monitoring capabilities ... also don't know if one has stopped hashing and would need a restart ..

waiting on a bfgminer support ...

Hi, my wiibox controller not detect my miner, any idea why?
Thank you

[darkfriend77]

...

Not bad for 5 pods with only 2 fans, eh?

...

You have done a stack of them removing the fans?

Can you show a picture ...

I was thinkg abbout building some piles with them removing the fans and exchanging them with slow 200mm ....

does your controller say lightning asic, if so then you need to find the ip address on your router underneath attached device. and use the ip address to access the controller.

if you have a controller from gridseed. just plug the power and Ethernet cable. wait 2 mins and run the scan on wiibox.net. best to access from google chrome, as it translates it into your preferable language

Im running with 800 now 900 gave me to many rejects.

rgdz,
bhai

Right, 900 = spit dummy
850 seems to be the sweet spot....

I tried this also and the results are:
1000MHz, just like I thought as it is per spec', and increments of 25MHz = impossible i.e. ain't programmed for it so if you try, the clock will just revert to default of 600MHz....

No magic black smoke!

Wolfey2014

yeah, I just had to try it

You can actually get better granularity than 25MHz, as various frequency dividers are supported.

Hi thank you,I have able to make it work.

guys with controller... DO NOT upgrade to 2.0.3... your root access will be cut!

[madzooka]

It works great ! thanks a lot for a guidebook you've made to the service

Here is my question, if you are using just the LTC portion of the chips, do you need the fan at all?

Do you need anything but the upper heatsink?

I have never seen a photo of the underside of the board (the fan side)

The thing draws 9.5 watts at 800 freq, how much cooling could it need?

Forget about racks and shelves, someone should figure out how to mount 50 of these things inside a PC case

But then we'd all be throwing away money buying a lot of dead weight i.e. heat sinks and fans! ;[
I've thought of the same thing.
I've had a couple of them apart. Every one I wanted to take the fan off of, I had to de-solder it from the pcb terminals.
I'm running 3 pods fanless and 2 with fans. One fan unit cools 3 pods and the other fan unit cools 2 pods.
Highest temp at 850MHz was a measly 85 degrees F. No sweat! May go completely fanless after I finish tuning this rig.
One of them was fukked up as it was obviously assembled by a careless worker. QC didn't catch it which means they too suck or are non-existant. OF course a bad one gets by once in a while anyway so....
If I can find a way to access those GC3355 chips, I'm going to build my own blades. Talk about saving money and time, big time!

Would also be great for GridChip to make the GC3356 LTC Only chip! That way they'd be able to Hash at 150 to 300KH/s per chip or 750KH/s to 1500KH/s per pod! There are only 4 cores available for LTD and a massive 160 cores for BTC, which is why BTC mining generates so much more heat. The more active cores there are, the more juice is required, the higher current draw goes up hence, the more power usage (in Watts) there is.

We ain't using them 160 BTC cores so there is a lot of wasted processing power lost right there! A lot less heat generated too but....Ooph! Kind of hurts, eh? ;[ I don't know if the BTC cores can be re-configured to run LTC as well via firmware updating...or not. I'm going to find out though. Probably not. Looks like the physical architecture / nature of the SHA processor is very different from Srypt. Just wasted chip and pcb space for now! Even if / when all cores are actively hashing Scrypt, the power useage goes up but I highly doubt that would be a limiting factor where profits are concerned. 1500 KH/s x 10 pods = 15000KH/s = $100+/- per day! That's what I'm talkin bout!

So, heat sinks, gone, make new improved Scrypt only ASIC's. They could charge more per pod but we'd all be making a lot more per pod too

Of course, if they abandon small 5 chip miners for 50/100 chip units, most folks won't be able to afford to play this part of the game ;( which could harm the crypto-currency markets too.

[darkfriend77]

well it's possible ... without fans ...

I know at least one person that does it ... since he couldn't find sleep beside the airport feeling ... that those fans give...

[darkfriend77]

I thought about building a 20 Gridseed-miner tower

like this ...  with 200mm fans in between



would look like electronical art ...

So some of my instances of the new CPU miner dont really ever report shares where as other will have reported 10+ in the same amount of time.

Is this something i should be worried about?(i guess it is cause i am)

I know id much rather have the share submission equal throughout the instances.

no, you should see hashing 'yay's all the time on each miner, some work faster than others but no more than a minute or two apart from what I'm seeing on mine.
If one hangs for a longer period of time, you have a comm port issue most likely. UART port bottlenecking.
Lower FIFO receive buffer down a couple ticks and see if it straightens out.
Don't worry about any of this stuff. It's all configurable.

Read my previous posts to get more familiar and handy with this issue.
Good luck!

And just how does one accomplish this? Spec's say 50MHz steps and mine didn't accept a 25MHz step request today. No reason to believe it will set at finer steps.
You saying otherwise? And if so, what's your evidence?

[wolfey2014]

Straighten me out on something here.
I've been following the rumors, comments, assertions etc. on btc for some time now and only tonight decided to take a deeper more critical look at it.
What I understand thus far, makes me ask...
Why is it not profitable to mine with the GC3355 5 chip miners?
From what the calculations on coinwarz.com shows, mining btc is way more profitable than mining LTC or any other scrypt coin for that matter.
Doesn't coinwarz's calculator take into consideration that btc is mined by thousands with super duper TH/s rigs?
Why the great skepticism on mining btc anymore?
Still, I read others posts about running antminers at only a few 1.6GH/s rates making profits of 6 to 8 bucks per day.What's so bad about that?
I mean,with 10 ant miners, one can theoretically earn $60/$80 per day. WTF is wrong with that? That't way better than mining Scryptcoins, not to say Scrypt isn't worth mining but it is indeed, worth - less.
So I don't get it since our beloved dual miners will run many times this rate - per pod -...making one up to hundreds of dollars per day!
I'm a little bit confused!
A little help by someone well versed and experienced on the subject of btc mining with ASICs or even GPU's,, if necessary Mining is mining. We ALL can mine BTC, in any case. Not ALL can mine the same types of Script. Obvious but, interesting.
Thanks!

There are more scrypt coins then SHA-256 coins and they are more profitable. BTC difficulty will rise so fast, your miner will be worthless very soon. In scrypt, your GPU's will probably be good until they die.

How high can the CPUminer overclock them

I am running on 850. I know it supports 900 but what about 950 or 1000?

I'm running at 850 also with positive results.
Also saving 10.5W of power by running 1 fan per 2 or 3 pods-stacked.
Seems to be working well.

I was just looking over the GC3355 datasheet and the max tested clock speed for LTC is 700MHz.
The chart goes on to run the BTC cores all the way up to 900MHz in 50MHz steps.
That's it.
I wouldn't try higher clock speeds. It either won't accept it or will spit dummy and produce nothing but nonsense or perhaps even blow the poor little chip's brains out! Ew! Beware of Magic Black Smoke!
Of course and as always, try this stuff at your own risk! You blow it, you eat it!
Good luck!
Wolfey2014

I have learned a lot from this guide. Question: How do I overclock? Can someone point me to the right direction please. Thanks.
