I have a P5N32-E SLI with e6400 core 2 duo 4GB Kingston 667 Ram and a evga 7600 gt ko and a evga 7600 gt co. The problem is whe nI try to run them in SLI. Whenever I add the second card in the pci-e #3 slot, it will not post. I tried the pci-e x8 slot (#2), and it will boot up with both cards just fine. I have the 24 pin connected, the 4 pin cpu power connected. I unplugged the usb connectors, along with the mouse and keyboard, no luck. I then tried just one stick in every slot, nothing. I sent for a new mb and its doing the exact same thing, so it must be something I'm doing. I tried both video cards and they both work fine. Any ideas please would be very helpfull. Thanks.
Looked up your videocards and one is basically a revision of the same board. So long as they are the same GPU (which they are) they should be able to work in conjunction for SLI. You said you have the 24 pin connector and extra 12V 4 pin CPU connectors in. Did you also plug in the extra power connectors for the graphics cards? They require more power than than the PCI-E slots can provide.
I beat the Internet... the end guy was hard
Thanks for the reply. Yeah, I checked for a power connector on the video cards, but there isn't any, and I checked the EVGA site, and the specs said the cards don't require a added power souce. Thanks:) I at a loss as to why the stupid things won't work...

I'm not, I just put a card in the #2 slot to see if it would boot, as per ASUS tech request. I have the second card in slot 3, but it will not boot when I do.
They should be in the blue slots.
Yeah, slot #1 and slot #3 are the pic-e X16 slots, the white is pci-e X8. Thats the problem I'm having, the computer wont post when I have a card in the #3 slot.
humm interesting, and its your second mobo? and still the same problem?
Yeah, I RMA the first one, now this one is doing the exact same thing. So unless I have another bad MB, it's something I'm doing.
Doesn't sound like anything you're doing.
Yeah I'm starting to think that too. I've never had any problems with ASUS boards before, next time I'll research the damn thing lol.
I was playing around with the memory voltages after seeing in PC Probe II that the NB voltage and memory voltage was a little low. I raised the memory voltage to 1.9 and finally got it to boot 1 time. Then nothing again, lol. THis is the worst ASUS board I have ever bought.
Yeah, user reviews for the board are not very good. I've actually stopped using Asus. Used to be every board I got from them was great but the number of DOA items kept rising. Lately I've been buying Gigabyte and have yet to encounter any problems or a DOA.
My guess is that since Asus sells so many boards they rush production and have slackened their QA.
