Asus ENGTX570 DCII (2x SLI) driver issue...

post #1 of 6
Thread Starter 
Okay, here we go. So I've two Asus ENGTX570 DCII (the huge suckers) in my rig. I've been battling with two issues regarding software and drivers since I've gotten them, and I wanted to run the situation through OCN to see if anyone has any ideas.

Problem 1: If I install the drivers that come with the GPUs, or download the latest drivers from Asus website associated with the DCIIs, Everything looks great save one problem. I have no option for SLI. The phyx option is there, but no SLI. Both cards are recognized by Win7 as well as NCP. So now I move into...

Problem 2: If I install the reference Asus GTX570 drivers, I now have SLI capability, but now Asus Smart doctor recognizes my top card as GPU 2, and my bottom as GPU 1. This is a problem because when you SLI these things, the fan control and overclocks are tied to both the cards. My temps on the top card are higher, and so it would be dandy if smart doctor would default to this as GPU 1. Basically, I have to go into smart doctor and change it to GPU 2 for the fan speeds to adjust to the highest temp card. Sort of annoying, but tolerable. I haven't changed anything but the drivers, mind you. I've uninstalled all display drivers, restart PC, install new drivers. I've deleted associated software such as gamerOSD and smart doctor, and reinstalled. I've tried all the different orders of installation, and have tried various versions of all of these. With the DCII drivers, smart doctor recognizes the top card as GPU 1. This is when my head splodes.

I shall provide virtual milk and cookies for whosoever shall provide a solution to this problem. What I would like to do is run the drivers meant for the DCIIs, and be able to set SLI (like I SHOULD be able to). I figured I'd take a stab here before fighting with the Asus forums. I really dislike asus support (but I love thier products).

Use option 2 and download MSI Afterburner, then use that to change the fan curve for each card.
Not positive if it'll work or not, but I'm pretty sure.

MSI afterburner wont allow me to adjust voltage (DCII is a non-reference). I'll go with that option once I've exhausted all other reasonable options with Asus. I'm thinking I need to do a complete driver sweep, which I'll probably do manually. Not looking forward to it. Still fishing for more suggestions though.

Okay. I've manually removed all driver files/software for nvidia, and tried a fresh install of both the original drivers, and the newest recommended by Asus. No dice, same problem (can't SLI). I also tried a fresh Windows install on a backup harddrive, and started from scratch. No dice. This has to be either hardware (which is wierd because SLI works when using Asus GTX570 drivers, newer Nvidia drivers than the DCII), or the drivers/software/OS conflict. Next step is sending an email to Asus support. /Sigh

Download Beta version of Afterburner. I can mod my voltage as I like.
