8800gtssli512 slow? help..

I hope this is the right place to ask a question like this.. I have two 8800gts 512s in my system with vista... driver- 7.15.11.6925 I had two 7900gtxs in before this and they ran wickedly! why can't I get the same performance out of my new cards? I went to nvidia, xfx (mine), and evga... there doesn't seem to be any help out there. I'm hoping someone answers this because I wanna play!

 

You might want to try the beta drivers if youre not already.

 

yeah awesome! thanks for responding. I have the driver installed that you listed, so that's not the problem.. the hot fixes could be though so I'll try those. These cards in sli should play Crysis great shouldn't they? also I tried to play fear with them and believe it or not my 7900gtx cards whomped for fps@average of over 80, and even above 200... I get like 18 with these new ones, what gives? sheesh.

 

microsoft is telling me that the latest hotfix doesn't apply to my computer... k this is what I have-

-a8n32-sli deluxe
-amd 4400+ x2

 

opps

-a8n32-sli deluxe
-amd 4400+ x2@2.42
-4 gigs mushkin em3200
-2x8800gts 512 xfx
-raid1x2 7200s
-soundblaster audigy2zs
-vista ultimate
-850w antec true power (with yellow racing stripes) lol~
-antec 900 case...

so yeah I should be able to play crysis at decent frame rates no?

 

Thanks for your help folks though I'm not to sure why beta drivers would work versus the other.. I'm gonna keep trying to see what else might work to get my frames up where they are supposed to be...

 

I think it's the Antec case....yup.
...But seriously. Have you uninstalled the driver for the video cards, and made sure you selected "Delete Drivers for this Device?" A lot of times that will work, from my experience.

 

Likely its that vista is more demanding on video, and slowing your framerates down.

 

Thanks Halo.. I apprieciate your getting back to me on the suject and I will take your advice and try the beta drivers.. heh, yeah it would be nice to see a little more hard work going into the drivers for vista.. know anywhere I can advertise a couple gtx7900s? as for the game I've been fiddling quite a bit lol! I got crysis to work. I just thought that I would have a bit better frame rate with sli.. oh well. anyways keep up the good work

 

creativebalance.. hey yeah in vista you can chosse in it's own window from a list of your drivers which ones you wanna use so I didn't have to delete them.. but sound advice thanks!

 

colemanguy, yeah your right I think, but I have four gigs of dual channel shouldn't that be enough to run everything? It's not the fastest but there is a lot of it.. I tried with aero on and off it doesn't seem to make a differance. I think I need to switch to a quad core. and then faster ram not more ram... I could be wrong. anyway thanks for the time! take it easy!
