just a quick question how are you running two 7300's in SLi. Did you jsut but two from apple and then get an sli cable or ???
What happens ot this configuration under osX ?
I am really keen to try this as an option till someone releases a better nvidia card for Mac Pro !
I bought my Mac Pro with one 7300GT and then bought another 7300GT from the marketplace for $100 delivered to the UK, which was a great deal. I put the second card in the slot above the first and used the SLI bridge from my DFI NF4 SLI-DR motherboard that's left over from my old PC system. Installed the modified nVidia drivers that enable SLI on Intel motherboards available
here. I activated SLI then activated coolbits which you can do by installing
this registry file and then used the nVidia driver's clock speed tools to overclock the core and memory to 480/485 for both of the cards. I originally had it at 485/475 but got graphics errors in games. I haven't spent a lot of time getting the maximum possible speeds yet although those aren't bad results for DDR2 7300GT cards.
I've been playing HL2 and the Sims 2 at 2560x1600. I can't remember if I've got AA/AF going, I think I have a little bit although it really doesn't make as much of a difference when using such a high resolution imo. HL2 is most definitely playable but isn't quite as smooth as my SLI'd 6800GTs ran HL2 in my A64/X2 machine - although that machine only drove a screen with a res of 1280x768 so the results aren't that bad in comparison!
