Hi, yes I'm new.

Glad to say my weekend project was setting up my very first Litecoin mining machine. After much reading and testing I have some of my own results to show and would appreciate any comments.

System Specs:
Processor: AMD FX-8350  AM3+ 8-Core
Graphics Card: 1 x Sapphire Radeon HD 7950 3GB
Motherboard: ASUS M5A99FX PRO R2.0 AM3+
RAM: Corsair 8GB (2x4GB)

Mining with GUIMiner-Scrypt alpha (7950 cgminer)
OS: Windows 7

After reading some setting configurations https://bitcointalk.org/index.php?topic=117221.0 I tried some tests and got conflicting info.

It seems when I pump up my concurrency and intensity I can get a reading of ~550khash/s in GUIMiner. But this actually significantly reduces my recognised rate in my mining pool. It seems the best settings in GUIMiner are it's defaults concurrency: 8192 and intensity: 13. For ~300khash/s recognised the same in both GUIMiner and Mining Pool.

Is this correct? Can anyone shed some light?
