Trying to upgrade from SLI GTX260 to SLI GTX560. After removing all of the drivers and then the 260s, installing the 560s and rebooting I get a long beep followed by BIOS code FF. I've since tried various combos of the 560s, reseating all components, resetting the BIOS by removing the battery for 10 mins and calling EVGA support only to be told I probably need to RMA my Mboard for a replacement. Before I go down this path, thought I'd publish my system specs just in case anyone can help.   Finally, as soon as I put the GTX260s back in, everything works with no issues

Hi Jeffrey,
thanks for the suggestions. Just one question - I'm not getting any video at boot up at all (so before I even get to the Windows start graphic) so wouldn't that indicate a wider problem than the video driver? On the power side, yes its getting the extra power via a couple of 6pin connectors for each card (4 total). LEDs are green on the 560s and fans are spinning

Instant FF at boot is usually hardware related. I would say to check everything to make sure that parts are seated and connected properly but, you have already done that....and when you put the 260's back in, all is well.

So, try each 560 by itself in the primary GFX slot and see if they will function properly individually. If one works and the other doesn't.....well, there ya go. If neither works then, you may have gotten 2 bad cards. If they both work by themselves and you just have an issue when you SLI them....try a different bridge.

EDIT: Just in case you don't already know this.....BEFORE you uninstall the GFX driver, ALWAYS turn off the Windows Automatic Update feature. This will prevent Windows from installing another driver before you can install the one you want to use. After you are all done then, turn it back on.

Jeffrey, I didn't explain the boot cycle in full I'm getting -  there is no video at all, the mboard does go through all of the various steps (can be seen from the onboard display) and about 1/3 of the way through the boot process I get a long single beep but the boot continues till I get FF displayed and then nothing. Doesn't shut down but also doesn't start loading Windows as I believe its waiting for user input but can't tell due to no video.
 
I've tried both 560s by themselves in all of the different slots and same result

Have another system either in house or at a friends you can try the 560's in?
 
I'm thinking this though, make sure the cards are fully seating in the PCIe slots. They might be hitting something.
I know if I do not put my GPU's in just right they hit on the case and don't go thru the slots and don't fully seat in the PCIe slot.
Don't think they changed any design so you should not be able to see any of the copper sticking above the PCIe slot where the cards PCB meets it. See if there is a difference in how it looks between your 260's and 560's.

Might try a 560 in another machine just to verify. You can never say never but 2 brand new ASUS 560s defective would be unusual. Yes the 560s were definitely fully seated - checked and rechecked

I am having a hard time understanding how it could be something wrong with the board since, the the 260's require more juice to run them than the 560's....and they work fine.

You definately should try the 560's in a different board. If they still do not work then, you know what to do....RMA. Next time maybe you should stick with EVGA GFX cards??  

You and me both re the hard time understanding. Actually if the 560's aren't working I'm going to return them to Frys and replace with a EVGA 580 if they have one

.....and then another one down the road, right?? Gotta SLI!!! I can hardly wait until I get my 2nd 460 at the end of this month. I miss my SLI sooooo bad. I ran 2 260's for a year with an old 8800GT Akimbo as dedicated PhysX and it was pretty good. Just running 1 460 now with one of the 260's for PhysX and it is very nice like that but......ya know!!!

 
So the Asus 560s are now returned and replaced with one EVGA 580. Dropped it in and bingo, works first time. Maybe you're right Jeffrey, I need to stick to EVGA in the future 
 
Thanks for the helpful suggestions

Yeppers, glad you have it sorted out and are back up and running.
Now don't forget to change your sig.
 
Hmm all this talk of SLI and dedicated physx cards makes me want to put in one of my old 8800's for physx or maybe my 275 but that would be major overkill.

Yea using 441W right now GPU and SMP folding. The 750W is why I did not go SLI on my 480's to begin with since this one was the 11th anniversary prize so I thought about it but then thought ahh forget it as I just bought this PSU just not long before I won the 480.
 
Plus I'm thinking of going a bit higher on my overclock so that will also eat into my spare wattage. Just on Dummy overclock now  as I gave up on trying to get my overclock stable a year or so ago at 3.4GHz.
 

im having similar issues with my cards i just receieved 2 evga gtx560's and been having issues with drivers first and now with games (cod:bo,crysis2demo) crash. upgraded from 1 evga gtx260 core 216. also im all my temps are fine ive already benchmarked/stresstesed with oc scanner/occt/3dmark11 and vantage finished the tests.(note monitor is 1920x1080 @60mhz max res).  Also while writing this post I've just noticed that I don't have windows 7 sp1 installed lol ,I turned off updates long ago. can that be a problem when running games? none of this happend this often until i threw on these 2 bad boys on my mobo.

Dude, this is the 2nd post in 2 threads of issues you are having. PLEASE start your own thread and post your issues in it to receive assistance in resolving them. Thank you.

Diff_1 .I cant answer here apparently im getting scolded by jeffrey for being a total noob at posting in forums. I'm not an experienced poster but I  this sounded exactly like the same issue i was having and the "thread owner" had already solved his problem and figured I could get help next.

I apologize if I came off that way. It is our Forum Ettiquette to not "hijack" another member's thread by posting/and working on our problems on them....related or not. Just start a new thread of your own, give it an appropriate title and we'll be very happy to try our best to help you resolve your issues.
EDIT: I see that you still have not posted you own thread yet....if you want help, why not??

If you have a problem please start a new thread so this does not confuse forum members with the original OP thread.
