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

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!

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.

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.

this is a basic failover strategy, it never checks for pool 0 again if it's alive.. so it won't work with betarigs.

Thanks for sharing it sandor - this looks so great. What a genius idea to autotune per chip. I started at 950Mhz on a Vmod1 Gridseed.

I just checked and all 5 chips have made it to 975Mhz on autotune.

Does this: minerd.exe --gc3355=\\.\COMxx,\\.\COMyy,\\.\COMzz mean one instance for multiple 5 chip miners? If so, do you total the chips or does it default to 5 chips per com port?

Yes, it's one instance of cpuminer for whatever number of miners you have connected. By default it's set to 5 chips per miner.

How can I adjust the freq from 1 chip? From all 5 (On one of my devices) only chip 3 gives HW errors. I want to clock only that one down but keep the rest at 1000Mhz.

Thanks!

That isn't possible ATM, but I can add support for that.

I would donate BTC if you can have cpuminer read from a config file (just like cgminer)

Something like

Code:

{
"pools" : [
{
"url" :"stratum+tcp://dogus.nut2pools.com:5585",
"user" : "simon66.gpu1",
"pass" : "1234"
},
{
"url" :"ltc.give-me-coins.com:3333",
"user" : "simon66.GPU1",
"pass" : "1234"

}
]
,
"devices" : [
{
"Name" : "Grid1 - Simon",
"port" : "\\.\COM1",
"freq" : 850,
"gc3355-autotune" : 1
},
{
"Name" :"Grid2 OC - Simon",
"port" :"\\.\COM2",
"freq" : 1225,
"gc3355-autotune" : 1
}
],
"kernel" : "scrypt",
"gc3355" : true
}

I'll see if I can add these my self (Then push it back to you); if I can find some time :/

I'm also trying this build with 2 gridseeds and client side I get ~989KH/s however poolside hasn't peaked above 730KH/s and it's been running for 4 hours now. With cgminer I would see around 990KH/s clientside and around 950KH/s-1.2MH/s poolside.

Is there something I haven't configured correctly? It doesn't seem that there is much to configure...but it never hurts to ask.

EDIT: Trying a different pool to see if I get similar results.

Hello.

I tried to compiled cpuminer from Git but with no luck.

Code:

git clone https://github.com/siklon/cpuminer-gc3355 cpuminer
sudo sh autogen.sh
sudo ./configure CFLAGS="-O3"
make

Everything seems fine during compile (not an expert on linux)

Don't get any accepts, something is wrong.. Any Ideas ?.

I had the same issue on my Pi. I checked my cables + usb hub and still couldn't get it to work. I just gave up and went windows.
I recommend waiting for a compiled Pi version.

That would be awsome! Because I know all 4 chips run fine at 1225 but only that one runs fine at 1175.

That's great, now people can use CPUminer with services as Betarig!

I'm getting right away a virus warning tho with this version, I'm not getting it with previous version.

Virus warning is common with mining software.

I've heard it yes, but never got one before this one. Scanner says "win exploit" blabla lol
