I know most of you guys must have way more experience with putting all of this together, and thank you for all the advice. I have a sneaking suspicion that maybe these two 460's I have are incompatible.
Card #1 is Zotac SE 768 megabyte 710MHZ 1800MHZ shader clock .975 volts
Card #2 is Zotac SE 768 megabyte 675 MHZ (lower shader clock, but exactly sure by how much) .987 voltage
I thought they were identical cards but it turns out they are slightly different. Anyone know if the different volts or clock is causing an incompatibility maybe?
There are a couple of things you should do to improve your setup:
- click "start", type in "msconfig", and press enter
- go to the "boot" tab, and set the SLI patch option as the default, and set the timeout to 0
You should also flash the bioses of the two cards so that they are the same. I use nvflash. What you'll need to do is:
- use nvflash to read your current bios
- make sure you save your current bios files in case you want to revert to stock
- use MSI afterburner to test the cards at the faster speed
- if it's stable, use nvflash to flash both cards to the faster speed
- the command I use in nvflash is "nvflash -i0 -4 -5 -6 bios.rom"
- to flash the second card, the command you use is "nvflash -i1 -4 -5 -6 bios.rom"
- I've got a USB drive all set up so that I can boot off of it into DOS to do all that stuff with nvflash; I don't think you can do it from within Windows (and even if you can I wouldn't recommend it)
- I also actually used FermiBiosEditor to overclock both of my GTX 460s to 850mhz on the core and 2100mhz on the memory at 1.087v
Thanks to the people who make the SLI patch possible by the way!
