SLI not an option in Nvidia CP
  1 / 2    
So I know a ton of people are having this problem and so am I. I just put a new computer together with 2 indenticle 550s in SLI. Windows and Nvidia both recognize 2 550s are indeed installed but whenever I go to Nvidia control Panel there is not SLI option at all. I double checked and mobo does support SLI I switched around the SLI connection to the 2 video cards and I have tried old Nvidia drivers New Nvidia drivers and Beta Nvidia drivers and none of them work. I have read something about Realtek network drivers conflicting but I dont know how accurate that is because I uninstall those drivers all together and still no SLI. Somone on another forum said that I should roll back my realtek network drivers but for Some reason I cant I get code 10s all the time when I do and still no SLI. Nvidia whats the deal with no SLI? Getting the feeling I shoulda just bought 1 570 for 70 dollars more than I paid for 2 550s. Please help me fix the issue.

Did you install all the BIOS/Chipset updates available off the web for your motherboard?
What graphics drivers have you tried so far?

um the current beta ones. the newest available ones 296.10? currently using 285.17. I used a 260 something one as well. I am sorry my memory isnt that good. The chipset update I will try that again. I was waiting for a replacement dvd drive to do them from the dvd since my dvd drive lense is kinda on the way out. let me try the chipset drivers and tell you what happens. Thanks for responding.

Have you,..

Checked in Nvidia CP/Manage 3D Settings/Global Settings to make sure everything in there is correct? - specifically SLI Rendering Mode and Multi-display/mixed-GPU acceleration

Only other things i can think of,...

SLI bridge in place and properly seated ?
Have you swapped both cards to make sure they both work?
Check the BIOS on each Vid card to make sure they're the same?
Does your PSU provide the wattage to drive 2 cards in SLI?

I have seated the SLI bridge flipped it around the other way and such as recommended in other things I have read. I have disabled each video card and plugged into each with my DVI cable and both work. my PSU is 730 watt. It seems to be a VERY common problem so I doubt my PSU is the problem. Someone on another forum said it had to do with conflicting network drivers but Rolling them back doesnt seem to be an option for me. the 3d settings are set right. SLI rendering mode? No SLI options show up in NVidia CP at all thats the problem.

graphics cards do not need to have the same bios to sli, my 2 pny 580's have different bios and the sli guide on this forum say's that the bios can be different. not trying to start any trouble just thought you might like to know for future reference. /thumbup.gif' class='bbc_emoticon' alt=':thumbup:' />

on the network driver this only applies if your board has the realtek lan driver, if so you can disable it in the bios just to test if it is your problem but if you have allready updated your mother board bios then i doubt the lan driver is your problem as most have put the updated driver in the new bios version. have you tried putting your mouse pointer where the sli option would be in the column on the left in NVCP as some have found it to be there but could not see it untill they put their mouse pointer there.

Just figured I would post what it looks like now that I have updated to 296.10 again.

mmm i didnt have sli issues with 296.10 but i had game issues so i am
running 295.73 with no issues. I am now at a loss on yours as everything you
have and everything you have performed it should work.

Only other thing I could suggest here would be to try a different SLI bridge.

I will try but from I read you dont even need the SLI bridge on to get the option to come up in Nvidia.

okay so I fixed the issue. I moved one of the video cards down a PCI slot so its in 1 and 3 instead of 1 and 2 reapplied the bridge and viola I boot into windows and Nvidia CP is like yo this system is SLI capable. :) I R Teh Man :)

cool except running one in the 3rd slot you will lose some performance of that card
but most of the time it's not enough to notice.
