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

[sandor111]

cpuminer crashes with this .bat file, I click okay on error then it works. Is that because this won't work with betarigs since it doesn't keep checking that pool to use?


:loop
minerd.exe --gc3355=\\.\COM4,\\.\COM5,\\.\COM6,\\.\COM7,\\.\COM8,\\.\COM9,\\.\COM10,\\.\COM11 --gc3355-autotune --gc3355-chips=40 --freq=825 --url=http://eu.betarigs.com:3333 --userpass=rrob-4660:x
minerd.exe --gc3355=\\.\COM4,\\.\COM5,\\.\COM6,\\.\COM7,\\.\COM8,\\.\COM9,\\.\COM10,\\.\COM11 --gc3355-autotune --gc3355-chips=40 --freq=825 --url=stratum+tcp://useast.wafflepool.com:3333 --userpass=BTCADDY:x
goto loop
pause

You forgot to add "--retries=1", and I don't think http protocol is supported, or I might have removed it for no reason.
And yes, as maxzilla pointed out, it doesn't go back to check the previous pool if the current pool is working.

Will the 10Miner Gridseed for $1500 will breakeven ?
Total Hash Rate 3600khs

No one knows for sure. But if you are going to spend $1500, you can better buy the blade miner of 5200khs.

Someone read the article about removing the thermal pad and put the paste in order to have better overclock?  It's this one: http://gridseed-blog.com/gridseed-overclocking-1000-mhz-without-voltmod/

Well, I suggest to avoid it because as I've thought the 5 chips and some others component aren't perfectly on the same plane, so the result is that one or more chips will not be even in contact with the thermal paste...WATCH OUT!

You can cleary see from this photo:


I've evenly tightened the screws more that one time but still there is a gap on most of the chips, in this case the U20 6pin chip is the culprit, it's a bit more high than other components so the heatsink surface touch only that chip.

I knew the pasty mod of Zig's was totally unworkable! There in your picture, is the proof!
Use the factory pads. They work fine! Simply torque all 4 screws evenly and snugly.
My miners all have factory pads on them and they all work perfectly!

I'm trying Sandor's new build of cpuminer but not sure what to put as the COM address? In device manager my STM32 virtual COM ports don't seem to have COM numbers. Any advice greatly appreciated, thanks!

p.s. I tried --gc3355=STM32 but this didn't seem to work.. still fails with "GetLastError:2".

Make sure to uninstall whatever drivers you have had installed (zadig etc.) for the STM32, then replug the USB and it should show up under COM ports.

Zadig doesnt appear to be installed as such, as I understand it, Zadig is a standalone .exe that lets you change drivers? I tried changing the driver to something other than WinUSB (with Zadig), uninstalling from device manager, and uninstalling the STM software. Still the gridseeds get instantly recognised as virtual STM ports with no port number when I plug them back in.

Is there something else I need to uninstall? I had read elsewhere that finding the COM port number wasn't necessary if you just set --gc3355=STM32 in the bat file - but this doesn't seem to work, in your build at least.

Also I tried setting the COM port from 1 though 15 in the BAT file to try and find the right number through trial and elimination, but no setting worked for me.

In the device manager right click the virtual STM32 and uninstall the driver make sure to click delete the driver software.  Plug back in the gridseeds and wait for them to be installed and assigned COM ports

I did check "delete driver software" when I removed them, but they still seem to get detected the same when I replug the USB, with no port numbers.

Yah, personally I don't feel that the latest cpuminer pooler is quite there yet. Nice try though!
I'm sticking with cpuminer oc version as it has been working perfectly for months without any drop outs.
Running several screens is of little concern when using scripts to run the whole smash anyway.
I'd like to see real time local hash rate in the same type / current screen, not some all together different version that now needs to be debugged by some end users.

He is having trouble getting the COM port detected in device manager, AFAIK this has nothing to do with cpuminer.

I've been mining with 12 gridseeds but I have an issue I haven't been able to figure out. I was running BFGminer with each gridseed doing around 320 khs. The pool was showing around 3.8 to 4 mhs.  When ever I push them higher than that the pool hash rate seems to drop off a fair bit. Down to around 2.5. I've tried on different pools and the same thing seems to keep happening. This was without getting any hardware errors. I thought it was perhaps an issue with BFGminer so I decided to give this latest version of CPUminer a go to see if I got better results.

The same thing seems to be happening with this miner as well. I've been running it for a couple of hours at 825 in autotune and it is displaying around 630 khs per gridseed?? The pool is showing around 3.2 mhs for all 12 gridseeds. This obviously doesn't seem right. Does anyone have any ideas what might be causing this? Why when I have a higher hash rate the pools show it lower? All 12 are connected via powered USB hub into a laptop running windows 7 x64 sp1. It's a relatively new laptop ( couple of years old ). Could it be an issue with cables or USB ports? Maybe I'm missing something?

Will the 10Miner Gridseed for $1500 will breakeven ?
Total Hash Rate 3600khs

No one knows for sure. But if you are going to spend $1500, you can better buy the blade miner of 5200khs.

i am asking myself with the Blade out, the Gridseeds are way to expensive right now.

I want buy 10 gridseeds also, but not want to pay more than 1000$, 1500$ seems insane.

I bought two , last one 130Euro. I think that never will break even, lol. But i just bought it for just4fun , want learn setting it up, Raspberry, playing around with Linux/Unix.

What´s the cheapest right now? (i´m in europe ,want buy 10 GS )

1350$ hm plus 100$ shipping thats 1450$, still too much.

For little bit more can have 80 chip Blade Miner, so no way

[jamieb81]

that's 1050€ so that's 105 euro per gridseed, cheaper than the 130

unfortunately I did not found 90$ price 65€ in europe, if you do, tell me I buy them right away )))

Not found also, this is indeed the best offer from a trustable company, thx.

Who in the right mind is buying 10 Gridseeds (50chips) now when can buy 80 Chips Blade for (nearly) same price.

Thats 30 Chips more!

i think wait some days ,  price of Gridseeds will be falling like a stone in the water and we see 750-999$ for 10 pcs very soon

I seem to have found the COM port numbers for my gridseeds using "USBDeview" (http://www.nirsoft.net/utils/usb_devices_view.html) program (COM11 & 12), but still cpuminer isn't finding them. Is this how things look for you guys?

try to change them to an other com port number below 10

Don't forget the "\\.\"

Sandor111, can you recompile me a version which allows 838 freq for my blades? Right now it only accepts 825 and 850. I turned off autotune.

That's just a display bug, if you set it to 838, it will show as 825 because it does 838 - 838 % 25

[rrob]

Can someone compile me a windows version of https://github.com/jmordica/cgminer-gc3355 to test?
