I have a Gigabyte GTX 780 (GV-N780OC-3GD, it has a 6 pin + 8 pin connector) and I have ran the modded BIOS from this thread no problem. I recently picked up another 780 for SLI, but this 780 is the GV-N780OC-3GD rev 2.0 and it has a 8 pin + 8 pin connector, not 6 + 8 like the first revision. I'm guessing it might have a slightly different PCB due to that difference. But could I still use the modded BIOS from that thread to flash it safely? I have attached the BIOS from the rev2 card if somebody would want to take a look at it for insight. Original 780 v2.zip

I'm not sure because I've never ran a dedicated PhysX card. How about this- can you use a program like MSI Afterburner to do it? I know if you go to settings and uncheck "Synchronize settings for similar graphics processors" it will let you adjust the cards you have in your system individually. So perhaps using this method you can just select the 690 (or maybe it shows up as 2 different GPUs since it's a dual GPU card) and overclock it accordingly.

If given the option I always prefer to flash BIOSes (especially motherboards) in DOS rather than Windows. It's so easy to do a one time setup on a flash drive to make it bootable. Since DOS is more low level and has less stuff going on in the background, it is much safer anyway to flash In DOS.

I would just go with SLI Windforce cards. I have one and have to say it is just so great. I'm talking GPU temperature of 68C with fan completely silent in the low 40% range (this is at stock with no OC for now). The cooler is so great I would still opt for it even though a little more hot air will be circulating in the case. Given your situation too where you have 200mm intake fans, it's more than enough to compensate. You can't go wrong with these cards.

I have the Gigabyte GTX 780 Windforce edition. It's really a great card and blows everything away at 1080p. I've had a lot of issues with BF3 and 320.18/320.11. I've read to do a clean install which I tried but still got artifacting (I deleted registry keys and hidden folders, etc...). I had to roll back to 314.22 and modify the inf file. Anybody else run into problems with BF3 on the GTX 780. And what do people use to OC nowadays? I've always been partial to MSI Afterburner but I would switch if something worked better.

I'm having troubles doing any sort of modification. I have the Gigabyte GV-N780OC-3GD (GTX 780 with Windforce Cooler.) I am on Windows 7 x64 with Nvidia drivers 314.22 (installed with modified inf file) because both 320.11/320.18 gave me artifacting in Battlefield 3. But anyway I want to disable boost and do some good old fashioned overclocking but here is what's going on. If I open NVFlash V5.134.0.1 in Windows it lets me do nvflash --protectoff and it works fine. I am running in an elevated command prompt by the way. If I try to save the BIOS with nvflash --save xxx.rom it just says "ERROR: PCI Block chain corrupted - PCI Expansion ROM Header not found - GetUEFISupport() failed". If I try in DOS with version v5.128.01 using a bootable flash drive, I get the exact same error. If I try to save the file with GPU-Z 0.7.1 it tells me "BIOS reading not supported on this device" even after doing nvflash --protectoff. Does anybody have a clue what I can do to get this fixed? I appreciate these BIOS mods by the way, can't wait to get this flashed. edit: Thanks for saving that. I just flashed the OC Bios and it worked fine. Not sure why I couldn't save it though
