Hey All,
To start with my RIG:
P55A-UD4P - Mother
2X260GTX in SLI (or at least i'd like it to work in SLI)
Intel i5 760 @ Stock for troubleshooting
4GB1600 Corsair DDR3 RAM
1000W mod PSU from Corsair i think
Windows 7 Ult 64
--------------------------------------------------------
Ok, I am sorry if this similar issue was posted before and i didnt find it (I really did look)
So basically this is what is going on - this is more or less new build - old video cards, and hard drives - everything else is new.
After I install Windows and all the latest drivers from Nvidia/Gigabyte sites - on first reboot it would not show me in the Nvidia control pane -l that i have an option to turn on SLI, even though it shows Phyx option and each card would be working and recognized individually.
Then i did more digging and found that its known that some Realtek LAN drivers have major issues with SLI, so I uninstalled LAN all together, restarted, and SLI is now working and option is back in Nvidia panel. Then i tried installing LAN driver after having SLI enabled - that did work, but sometimes when i am browsing web PC BSOD's, or when i am rebooting it boots into windows - with Drivers for video cards being disabled - saying that Windows found problems with video adapters and disabled them, this happens once in a while. When i have single card enabled everything is ok ...
So this leads me to think Realtek driver is conflicting with the SLI bus or smth .. anyone resolved this ??? Maybe with an older realtek LAN driver.
Its funny thing that windows could not install them by default, even though this mobo is pretty new.
This motherboard is pretty popular i think, and so is SLI and Win7... some one??
Please advice.
Thanks!

I knew about the problems with the conflict between the LAN and the nVidea cards but as far as I know there hasn't been a fix. This is one reason I run Radeon cards instead.
-
Ya, that makes me wonder.
Well anyways, all the other threads I read about this similar issue - was solved by rolling back the Lan driver. In my case - windows did not even find a driver for this lan adapter, so there is no "roll bacK" option avail. Any ideas?
This is RTL8111 driver, might this be the only motherboard that is using it?
-
Have you been on the Realtek site to see if they have any older version of the driver? And no this can't be the only motherboard using it. Sorry I can't help more but I am surprised that nobody else has come forward with any help yet.

Is the BIOS up to data?
Try setting the following in the BIOS.
Turbo SATA3 / USB3.0 > Disabled
Onboard H/W LAN2 > Disabled

So far - installed latest LAN Realtek driver from Realtek site, and flashed bios to F13 i think it is... no issues the whole day.
Even with runnin a mild overclock of 3.36Ghz on CPU and ram at native 1600 vs 1333... will report in tomorrow.

Looking hopefull, will keep my fingers crossed for you. ;)

Reporting in...
No issues so far - 5 hours of SC2... browsing.. youtubing...Stable OC @ 3.57 now.
So i think its good to go, looks like drivers from realteks site and newest BIOS did the trick.
:) one more happy user here.
