Trying To Get More MH/s Litecoin Mining

I am relatively new to this but do have technical abilities like overclocking, etc. Here’s what I’m working with:

AMD A6 3620 APU w/Rade

Radeon HD 6530D

Driver: AMD Catalyst 15.7.1

Also installed the recommended SDK for the AMD.

Win 7 64 bit Home Premium

Tried both the cgminer from Kalrof and the version included in the GUIMiner -script download, and the best is around 42-43 KH/s. Tried the full GUIMiner and it was too unstable to connect on my system…it seems.

Been looking around and finding people with (what seems to be) lesser graphics getting above 100, and some in the area of 200 KH/s. If I can get into the 80-100 MH/s I would be happy. So I have tried all their settings, and keep getting lower numbers than I had to start with, or the driver crashes…which brings me to the second issue.

If I set the intensity above 16 the driver will crash. It reloads, but CGMiner stops working and has to be reloaded, too. This also happens when using xintensity above 225…and at 225 cgminer crashed after three days.

I’ve played with everything I can think of, in the .conf file and through flags. Any help would be sincerely appreciated! I want to do this, but if it’s gonna take 3 months to get a single litecoin then I may as well go back to writing… tongue.gif

Also: Would it be possible to use both the GPU and the APU simultaneously? I haven’t found much on this subject anywhere…

Here’s a link to the complete specs on the Radeon: http://www.pc-specs….on_HD_6530D/489

Here’s a look at my .bat, file:

Again, THANKS for any help you can provide!
