This is working great getting much better resuts than with cgminer/bfgminer on my blades. I am not sure how I can run one instance of cpuminer with blades and gridseeds though. Is this possible or would it have to be 2 separate instances due to the chips=40 or chips=5 flags?
Thanks
Yes this will require two instances.
I'm experiencing an annoying issue using CPUMiner. My Gridseeds, especially the G-Blades, stop sending shares in a middle of nowhere that I'm forced to restart the device every5~10 minutes or so. No I don't have such problem using Zadig+cgminer. Anyone know how to fix this problem? Any help would be appreciated. Thanks...
Is that on Windows? Did you try the latest build from

Yes I'm on Windows 7 Professional x64, using STM's com port driver and latest binary but problem still persists. Do you have some debug option available so I can possibly track down the root cause?
Check your COM port settings.
Wolfey2014's idea to turn off FIFO buffers.
Personally I never had a problem on Windows with cpuminer (even before disabling FIFO).
Thanks for the recognition Sandor! I'm flattered
Yep, FIFO buffers seem to act like a Slowly Clogging Drain pipe! Little by little it builds up more and more crud and eventually stops up completely and kills the comm' flow = no mining.
This is due largely to the way FIFO buffers are set up to handle two way data streams. The 16550 UART protocol is designed to work with printers, faxes, hard drives etc. that flow data intermittently thereby making it easy for the FIFO's to do their thing. But when you have constant high speed two way data traffic as with our miners, it's overwhelming the buffers and eventually an overflow problem occurs, data packets are lost into the ether and the system spits dummy and halts because it forgot which packets go where and when. Lost data = lost instructions = drop outs! End of story = PIA random restarts.
Turn off FIFO's = all clear pipes = ZERO drop outs = wonderful 24/7 no fuss, no muss stable operation = frikkin !!yay!! city = more profit$!!!!
They didn't say you should remove the pads. Just use thermal paste on the chips to get EXTRA contact with the thermal pads.
