Hi, I'm super frustrated with scrypt mining!

[Mute]

Hey everyone. I'm new to the forum, but have been lurking for a couple weeks scoping out the mining ecosystem.

So I finally went and picked up a Radeon 7970 to take a crack at mining Feathercoins, but I'm running into some major issues.

I suppose this should really be in the support area, but this is the only place I can post.

I installed the Radeon 13.1 drivers and OpenCL 2.7, and got started with cgminer. Everything was working as expected, and I was getting a somewhat low but respectable 500Kh/s.

I started tweaking settings in the the conf file, and now whenever I start cgminer I am only getting 20-30Kh/s and the rest of the system is running really slowly as well.

I've deleted all conf files, started cgminer with only server, username, and password arguments and no other modifications, and it's still happening.

I've used the AMD removal tool to completely remove all drivers and software, and then reinstalled drivers and OpenCL. This worked once, but then as soon as I close and reopen cgminer, I experience the same issue. Now, removing and reinstalling doesn't seem to work anymore.

I've also tried bfgminer, but experience the same result.

GPU-Z says that the 7970 is running at 80-90% load, but it's temperature is relatively low (70C) and the fan speed never goes about 50%. Dynamic memory usage is high, at 2800MB. GPU-Z reports that Dedicated memory is running at 0, but I gather that this is a Windows 8 problem.

Do you have any suggestions? Thanks for your help!

paste your .conf  file contents here and we can take a look at it to see if there may be something wrong with it.

Sure, I will. Thing is, it operates the same with or without a configuration file.

If I try to change the settings within cgminer, and then write a new cgminer.conf, it doesn't write the adjusted settings. It's like it's stored the settings somewhere and won't accept any input to change them.

Here is my batch file:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --config cgminer.conf
