Hi all,
I am a noob at this whole bitcoin mining business, so go easy on me!
First off, my system specs may be usefull in arriving at a fix for this issue:
CPU: i5 2500k at 3.7 GHz . GPUs: 2x EVGA GTX580 1.5GB in SLI . Memory: 2x4GB DDR3 1333MHz. HDD: Raid0 of Velociraptors with 60 GB SSD caching via intel smart response. OS: Windows 7 Ultimate x64. Mining for Slush's pool via guiminer.

My problem is 2fold (and likely related!). First off, it seems that no matter what I do I cannot exceed 150 Mhash/s. Second, only 1 of my 580s seems to be getting used! I've tried creating a second miner (one for each GPU), as well as running just one. I've disabled and reenabled SLI. I removed and readded my second GPU. Not sure where to go from here! Are there any flags needed to make GUIMiner use both cards?
Let me know! Any and all responses are appreciated!
Thanks!

NVidia cards are costly trash for mining. Use an ATI instead.

Ya I did manage to get both cards going (had to disable surroundview), however both combined are throwing down 300 Mhash/s. VERY disappointed that 1 ATI 5870 can smoke both my 580s!! I'll be picking up ATI for a mining rig.
