Use an older version of cgminer... 3.1.1 for example
Do you know any versions of CGminer which are known not to cause a lot of issues?3.1.1

3.1.1
December 06, 2013, 08:18:56 AM
I've run my 7850 with these settings on cgminer 3.1.0, 3.2.2 and 3.7.2:
-I 17 --thread-concurrency 20480 -w 256 -g 1
or
-I 13 --thread-concurrency 8192 -w 256 -g 2
Either are ok for me. I get around 300kh/s at GPU clock 860, memory clock 1150. People who are willing to overclock can get better results. I don't like how some things are displayed on 3.7.2 though.
Change the intensity (the -I #number) depending on how far your card can go and how unresponsive a PC yourself can put up with. 4GB RAM is enough, that shouldn't be the problem IMO. If you're running one or two 7850 card, that shouldn't be demanding on the PSU either.
Edit: In cgminer, A means accepted shares count, R means rejected count, and HW is the number of hardware errors. Your screenshot does show a lot of HW's.

Both pools have notoriously bad predictions of estimated mining power. I mine at 220 kh/s and it displays me at 50- 150 kh/s.
You should not trust them below 500kh/s.
I do get the expected amount of coins based on ltc and ftc calculators.
How far are you of of the estimate by the calculators?
Some points:
- Update video/open cl driver
- What are the PSU line variations
- PSU health?
- Revert to cgminer 3.1.1, most stable for me.
- What is the cpu load? Not cpu mining as well right? Try it without cpu loading.
if i fixed it: 14e4VVFM9eHdunHxpGgswBf4N4iiVdmeMD
The calculators say 0.15 LTC/day, but I think I'm earning about 1/3 of that.You should not trust them below 500kh/s.

The CPU load is always 5% when GPU mining. I don't CPU mine.
The system has 4 GB RAM, but only 2 GB is being used while mining.
And the PSU is a Raidmax 630w; never had any problems with it. How would I find the health of the power supply?
And here's CGminer with the --verbose argument:

What are the hardware errors btw?

try cgminer 3.2 or increasing your system RAM

what's the temperature of gpu ?

Although this story involves mining Litecoins, not bitcoins, I think that the logic here is the same.
I started mining Litecoins and Feathercoins about 5 days ago. I wondered why my mining pools, WeMineLTC and WeMineFTC, always showed my hash rate as 80 Kh/s, although GCminer 3.7.2 reported 330 Kh/s.
So today I made a small Node.js program to interact with the CGminer API, and it seems that the mine program has a large rate of hardware errors. There's about 2 new errors every second. Of course, no notifications about this appear in the console window, so I never knew about it. I also noticed that the amount crypto-coins I was earning each day were lower than expected.
I am not happy about what is happening to all of my hard work.
Command-line arguments:
Regardless of which pool I use, the error amount remains the same. I thought this was due to overclocking, but I lowered the speeds to default, and then increased the voltage on top of that. But that changed nothing.
Video driver: AMD Catalyst 13.9
RAM: 4 GB
OS: Windows 8 x64
So how would I fix this
