Topic: [GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning - page 86. (Read 308807 times)

I'm on Windows 8 64bit. Mine also came up as something other than "CP2102 USB to UART Bridge Controller,'' it might have been STM port as that sounds familiar.
Is your error in Zadig or Cgminer?
Did you try just disabling and re-enabling the virtual port in device manager? That seems to fix the no device detected error in cgminer for me

What OS are you using?  I'm on Win 7 64bit.  Zadig installs ok, I just get an error saying no device detected.

When I install Zadig is shows up as a STM com port, not "CP2102 USB to UART Bridge Controller" as mentioned on the blog.  Not sure this really makes a difference.

I'll try again tomorrow, I'd like to get GPU and ASIC's mining happily with one CMD window open.

I have mine working in single core mode on windows using the cgminer and guide at http://cryptomining-blog.com/1262-download-cgminer-3-7-2-for-windows-scrypt-mining-on-gridseed-5-chip-gc3355-asics/

I have found that after every use I have to unplug and plug it back in again or disable and re-enable in device manager.
Cgminer is reporting 404 khash/s with 950mhz clock. It got to 424 on 1000mhz but I just figured that I'd let it run at 950mhz because its probably more stable at that speed (although I haven't had any hardware errors yet). I don't have a good way of measuring the temperature, but it isn't all that warm to the touch. Also, it reports it hashrate, so you don't have to use the pool's inaccurate data.

I can try and answer any questions about setting it up

Wolfey, I can't tell if you are being serious or just fucking with me.  Either way, I've added my "cents" below.

I think if it were possible they would have done it already.  An ASIC cannot be reprogrammed.  It can only do what it was programmed to do.  I'm thinking the chip was made with LTC cores and BTC cores, the LTC can LTC and the BTC can BTC.  That's it.  The fact that they can't run at full hash at the same time leads me to believe there are shared resources like memory being used or maybe a thermal ceiling imposed by the other components.  I'm not an electronics engineer, but don't hold your breath for some magical hashes where they can't be had.

eh at one point i had 10 units hashing with it. all solid at 360 some errors tho so it is possible.

No.  And installing zadig caused my display driver to stop working.  So I went from 1100 Kh/s to 0 Kh/s to try this out.

Luckily using a restore point before the zadig driver was installed got everything working again and I'm happily hashing.

I am a little peeved I just lost 1/2 hour of sleep though.

any with st32 com ports get this new cgminer working?

Maybe he just thinks mining btc is fun, and don't forget that it could become more profitable if the value of btc goes up as predicted. Those miniscule Btc fractions will go up in value as well!
Don't get me wrong. You are right in what you say too.

I would love to see someone find a way to reprogram the GC3355's to utilize the otherwise unused btc cores to run Scrypt! I mean, I know the firmware probably won't allow it but the engineers saw fit to only alot 4 cores for Scrypt mining and alot 160 cores for btc frikkin mining. What a waste! if you aren't using them! Give the algorithms are different for both, the processors are still just FETs (transistors) that are either on or off i.e. 1 or 0 just like the Scrypt cores are. So theoretically, they can be re-programmed to run Scrypt! Now that would be a vast improvement!

Then the GS5's would really crank out the hashes. I mean they'd probably be hashing at several times the current rate! And even though they would draw more power, it wouldn't be as much as SHA processing uses because Scrypt is much more efficient, electronically speaking, than SHA-256.
Yeah, that would be cool!

Just my 55000 quarks!

New cgminer that works in LTC only mode:  http://cryptomining-blog.com/1262-download-cgminer-3-7-2-for-windows-scrypt-mining-on-gridseed-5-chip-gc3355-asics/

Shows local stats and HW.  A step in the right direction.  I don't think fan control will ever be an option, but here's hoping.

EDIT: Doesn't work  Had a pretty bad experience trying to get it to.

I don't get why you would want to dual mine or mine sha-256 with these.  LTC profitability > BTC profitability.  If you dual mine, your LTC hashrate is going down to compensate, it's not like you are leaving the BTC power on the table by not enabling it.  From what I've heard, you can get 2.5 GH/s BTC and 200 Kh/s LTC while dual mining at stock clocks, and you are using more power, to mine less profitable coins.  If you want to mine BTC there are much more less expensive ASICs that can get higher hashrates for less money and less power and you won't be wasting your more profitable hashes on your Gridseed.

I have this same issue with the name not showing like in the screenshot.

I just need to rename it to CP2102 etc..?

Red? Not sure what kind of PSU you're talking about, but regular on a regular PC PSU, red is 5v. You need 12v to run a GS5 device. Use the Yellow (12v) wire and choose any black wire for the ground.

Sorry if I understood your question wrong.

I dont have CP2102 USB to UART bridge control do i just install it on the comm port? I did that but it still wouldnt work. Running windows 8.1 :/

Fucked up thing is i had 10 showing up and then now i cant get shit...

The PSU has + and -

The cords are Red and white

Just wire them in per the directions as many as you need to the three sets of terminals..

I would guess.....
If your com/lpt port drivers in device manager still show.
First, close Zadikitup, then go into device manager and refresh the drivers via right click on comm port then click on 'scan for hardware changes'.
Then unplug and plug back in your GS5 and you should be good to go.
I think this might work instead of re-installing the STMelectronics Virtual Comm Port drivers...
That is unless Zadickitallup overwrote or deleted them...
I'm very leery of converting over to cgminer 3.7.2 and having to install Zadig after having cpuminer and my GS5s running like a top for a few days now!
I wrote in to Crypto Mining Blog and asked about them adding real time hash rate to cpuminer. They suggested I convert to cgminer.
I thought it was a good idea when I found out that overclocking evidently works better with cg but now I'm reading that, maybe it ain't a good idea until a firmware upgrade is performed, if that ever happens, right? If cgminer turns out to be stabilizing higher clock speeds i.e. 900, 1000, 1100, 1200...then I'll consider it very strongly.
It seems no one except the very astute and experienced programmer types can figure out how to dual mine.
I'd like to try that soon, myself! No need in letting those btc fractions going to someone with a FIFTY THOUSAND DOLLAR - billion kazillion hashes per second super duper coin poopers!
As for now....
They are hashing away very nicely with CPUMINER at 850MHz! Hey, if it ain't broke, don't bypass it with some other shyt! USE the crap out of it! $$$$$$

Guys, so how to run more then 5 miners per PSU? Can someone please explain how to wire it correctly?

Manually change the driver in computer management or close zadig unplug the device and then re-install the gridseed drivers.

Similar problem. I can only get one or the other.

How do I revert back, as now I cannot seem to scrypt mine with the miner ony sha

EDIT: I reinstalled the STM virtual comport driver and back to mining scrypt. In Zadig I do not have the same options as shown in the how to dual mine link above. I do not see CP2102 USB to UART bridge control option listed there anywhere. I installed this driver and it still does not show up there

OK followed this, when I downloaded Zadig there was nothing in the drop down menu, i had to select list all devices, now STM32 virtual com port came up and I installed the driver. I am now mining BTC side but my Scrypt side now fails even with the --dual option added to the bat file!!!

There is no where in the drop down menu that i have the same option as on the how to link "cp2102 usb to uart bridge controller "
