Miner help please

[darthgremlin1701]

Tech Specs:
OS: Windows 10 Home
Miner: Lightning ASIC 5 chip Gridseed dual miner
BTC Program:   CGMiner 3.8.5 gridseed windows
BAT Command (Removed user and pass): cgminer.exe -o stratum+tcp://eu.multipool.us:8888 -u x -p x --gridseed-options=baud=115200,freq=450,chips=5,modules=1,usefifo=0,btc=16 --hotplug=0


Issue: When in dual mode, Scrypt side works fine, BTC programme shows hashrate but does not show accepts. Error shows Pool 0 requested restart of work. it then changes difficulty and repeats the same.

Uninstall and reinstall of sortware tried,

Your miner is likely SO SLOW it's not generating enough hashrate to get any accepts on the BTC (SHA256) side.

 The old Gridseed GC3355 based miners FOR SHA256 were very very low hashrate, and have been a waste of power for Bitcoin/similar for quite a long time now.

 They're getting very marginal even on the Scrypt side - worthwhile if you have FREE power, but anything over about 4c/KWH and you're losing money with them even on Litecoin.

Thanks for replies guys.

Speed wish I actually think my miner is okay. ON SCRYPT it hashs around 500 MHz with accepts fairly regularly. not huge but does work.
ON SHA256 speed when pushed on SOLO BTC was over 6GH so that seems ok speed wise for now so I don't get where the Slow speed comment is coming from. I know people now work in TerraHashs but surely these speeds are enough to get accepts on both?

500 MH/s on the Scrypt side? I think you misread it, should be more like 500 kH/s

 The 40-chip "blades" only manage 2.5-3 MH/s depending on how hard you push them, your Lightning is only 5 of the same chip.


 6 GH/s on Bitcoin is tiny - the old Antminer S5 (which is outdated tech and a moneyLOSER for most folks today) did over 1100 GH/s, while current S9 units are commonly 10 TIMES that.
