Hey all,

So I can mine BTC fine, but I want to mine LTC....but I always crash.

I have tried using multiple configurations in guiminer scrypt, reaper, and CGminer.

I have a sapphire 7950.  It came clocked like this:
GPU Clock: 925
Memory Clock: 1250
VDDC: 1250

This card is in a PCI 2.0 X16 express slot
I have 8GB of Ram.

My best success is using the high usage in setting in Guiminer-scrypt....sometimes I can up to 3 hours before it crashes, at about 530khash/sec.

I am using the 13.4 Catalyst Drivers and I think the 2.8 SDK  Whenever I try to reinstall the SDK I get a failure....not sure if that is because I upgraded to 13.4 catalyst.

Any ideas?

I never go over 75 celcius and my PSU is 730W

If I run CGminer...my comp crashes

If I run guiminer scrypt I get stuck on compiling kernal

and if I try reaper I get this: http://anonymouse.org/cgi-bin/anon-www.cgi/http://img90.imageshack.us/img90/8959/reaperfail.png
