Hi   Ok I tried those settings, but got around the same results approx 560 - 565khz these numbers worked the same as my settings and were stable, but no improvement   

Seems that score is my limit   

Nevermind thanks for helping!

Hi  Ok will do thanks I will post results later 

Try this -  go to your device manager winkey+pause, then select your onboard graphics and disable (even if you are certain that your graphics card is the default)

Reboot your PC, and hopefully you should be full speed.

To add - using Windows 7 64bit 

Just joined, will mine in a bit 

I guess Wow had one of the first alternative currency, with their Wow gold.  People still pay real cash for it via gold farmers.

Litecoin will succeed too, I think

How about Feathercoin, do you think these have a chance?

Hi   I recently purchase a Sapphire 7970, the one with the 925mhz core clock (21197-00)

I have browsed these forums, and Googled for overclocking advice, as I seem unable to get more than 560khash out of it.

Am using cgminer with and without GuiMiner Scrypt.   

Settings are - 8192 threads   1 vector    Gpu threads 2    w 256    intensity 13

Then using Sapphire Trixx -   GPU clock 1085     Memory clock 1500     VDDC 1200     Board Power li 20     = 560khz

These seem to be the only settings my PC can handle, if I try to increase the clocks further, the PC freezes.

I have a good Corsair 850w psu, 8gb of ram and an i7 2600k cpu

Gpu temps are managed by Trixx, and they are fine.  Cpu temps are good also.

Not sure if it is worth persisting, or just settle for the 560?

Advice appreciated
