I'm having some big issues with my Gridseed 5 chip miner.

The issues are:
1.When I used the official miner (CPUMiner one I think),no matter how many times it shows 'Dispatching new work...' I never see any shares submitted to the pools I use (no matter which pool I use and with their corrent URLs,clevermining.com,multipool.us and coinshift.com) so I gave up ever hoping I'd get the full 400+Kh/s as promised from my miner so I changed to CGminer 3.72 which does get shares submitted but I get much less than half of the total hashpower/coins I'm supposed to have mined on all the pools I've used.
2.CGminer often says accepted yet I never see the shares in my pool even though my internet connections ok and plugged in ok via the USB port.

I've tried everything I know of to remedy this but to no avail and am pretty frustrated now since there's no improvement and the instructions are even harder to understand than why I'm having issues in the first place.

If someone can just help me get back on track,I'd really apreciate this as I didn't spend nearly £300 for a miner that only performs at 50% or less of it's capacity (paperwight).Thanks Smiley

First, you're not going to get a stable 400k hash out of a gridseed. You'd need to be running at 950 to do that, and you'd be getting a number of HW errors if you did. I've been running pretty stable at 900 with a couple of HW errors but this gives about 380k. Most people run it at 850 which is around 360k.

This is what I use for cgminer:

cgminer.exe --scrypt -o yourpooladdress -u username -p password --gridseed-options=baud=115200,freq=900,chips=5 --hotplug 0

If you get too many errors, change 900 to 850.

With cgminer, you'll see a low WU. Ignore it (it's incorrect). If cgminer is showing a correct "A" count (depicted by A: in the output) but you're not seeing it on your pool, be sure you have the correct wallet address. A number of pools gladly accept "donations" from people with incorrect addresses.

If none of this applies to you, post sample output from cgminer so we can see what's going on.

Anything above 850 Mhz performs worse, the hashrate cgminer displays is nothing like your 'actual' hashrate.

Ah, so none of the miners really report anything well about these devices. And the pools are notorious for their inaccuracy for hashrates as well.

I guess I'll have to dive into the schematics of the chip, the bios, and drivers to see if there's a way to do that. If the miner is reporting 380k and the pool is reporting 410k but I'm really only getting 300k, that's irritating to say the least.

One things for sure, the person with their clock set to 1000 is going to run into a lot of issues.
