GPU2

[snowbird48]

G'day, I am currently running v.623 Classic systray client. It runs steadily without issues. I would now like to run v.623 GPU2 systray client as well. I have a pair of GTX 285's in SLI. I understand I will need to use the -gpu N line and possibly the -force gpu ........line. Do I have to switch off the SLI in nvidia control centre? My OS is windows 7/64 bit.

-Core i7 920 @ 3.6GHz
-12GB DDR3-1333 DRAM
-1250W PSU
-Rampage lll extreme mobo

Thanks for any advisement

Welcome to the F@H Forum snowbird48,

For multiple GPU installation, please read this GPU Guide. You will have to use -gpu 0 and -gpu 1 flags. You might need the -forcegpu nvidia_g80 flag too. If you have the latest drivers from Nvidia, I don't think that you need SLI disabled for folding.

or better yet, use the FAHTracker program. it makes the implementation of the dual gpu so much easier.

Welcome to the Fold, Snowbird48. Latest clients and appropriate drivers allow you to run GPU clients with/without SLI. Also, they should work fine without any dummy plugs for the monitors. Suggest you also add the -verbosity 9 flag to give you more info in the log should you need to troubleshoot any problems. Fold on.

Thanks for the pointers PantherX and divery4eyes. Nvidia driver is 260.99, the most current. Being quite new at this going to enable one GPU and watch things for a bit. I know this makes a bit more work for enabling the other. In reading through a lot of posts on here I see a number of folders suggesting to use Driver Wiper or a similar utility, then do a clean GPU driver install. Is F@H GPU client a bit picky? I do not mind taking the time if it puts a hedge on first time success running the client.

Thanks for the info HendricksSA. Folding on.

The application is called Driver Sweeper (Details) and we recommend it because when uninstalling older drivers, the default uninstallers (from ATI/AMD/Nvidia) may leave some left-overs which may cause an issue.
