A little help for a moron please?

good luck
Yeah I'm using 1 and 2.
I'm now feeling one step closer, with the new bios and igpu selected in the bios, the system works (obviously from the internal HDMI) and the gpus no longer do their funny little light show, but the SLI bridge remains off (I guess because the cards aren't actually on despite being lit up).
I haven't tried forcing 3.0 - is that in the sabertooth manual?

Another step closer... the reason for the weird Q-LED behaviour is a setting in the BIOS that turns them all on after POSTing, which is the opposite of what the manual is saying to expect.
With both cards inserted but booting off the IGPU when I go into bios I can see the status of the GPUs which report correctly but I can't see where it would state any voltages.

I only see a diagram of the settings page at 3.6 - no 3.6.3 or description of that function?
Anyway I changed them to gen3 from just finding the setting in the bios, but now that I've gone back to auto rather then igpu we are back to the original problem.
The only improvement so far is that having turned of that stupid QLED setting I can see it is throwing a VGA error on post when using the 980ti's

That leads me to think it is still likely a pcie power cables supply problem...
Re double check them.....just to be sure it isn't a cable install hiccup
Especially double check psu end for full connector insertion

They won't run in SLI unless you set them to in windows hense the bridge lighting up and switching off. Set them to SLI in nvidia control panel.
Also if they are in SLI mode download evga led controller. I've known mine been off and it was just set to off in the led controller.
If your not posting have you updated to latest bios via USB? One thing to try is a voltmeter or if you can just swap the plugs from GPU 1 to GPU 2 if one is known working. Is there any kind of led indication on the board as to what pcie lanes are being used?
HDMI, display port plugged into GPU 1?

well that is interesting...
Having previously set the BIOS back to auto I was back to not being able to post. I unplugged the PCIe connectors to check voltages (which are all fine btw - my meter says 11.9v across all of the pin pairs) the computer just booted usin gthe Igpu - is that because it considered the cards to be off with the PCIE cables unplugged and selected the Igpu instead? However, wouldn't that suggest that if there was an issue with the PCI-E cables that it would just default to that behaviour?
I'll check out the software tyler - cheers. I can't install the NVidia stuff without an NVidia gpu though, and currently the only way I can get into windows is by disabling the GPUs.
Edit - seems that was a one time occurrence.
Anyway... I've checked all pins are workig on the PCI-E cable, all bottom pins on the 6pins are ground all upper pins are 11.9v and the +2s are grounds. Fully reseated into the gfx card connectors after testing and no dice. I don't think it's a power issue.

Is there any settings in the bios to change pcie lane? That way you might be able to connect each GPU in turn to HDMI/ display port and see if you can get a signal out of either of them. Could be dodgy pcie lane or card but both of them giving no signal is odd.
I can POST as long as the 980ti's are disconnected. The moment I connect either of them, no POST and a VGA error led lights up on the QLED indicator.
I've already updated to latest bios and when using the igpu I have full access so I can see the update has taken.
Unfortunately not, this is the first PC I've owned for well over a decade. Other than the small POS that I used to use to drive my CNC, but that is just integrated gpu so nothing to pilfer.
The renewing of my PC experience is thus far not great lol.
I don't really know what my options are at this point - power seems fine, PC works fine without the GPU's but what are the odds of having two weird GPUs... Given that it doesn't seem to post with either on its own I'm just totally stumped.

Going to suggest one more option to try, but other than that, I am running out of ideas given what spares you seem to currently have available, and your current build status, ie watercooled up
Re manual 3.6.4
select pci express config to gen3 rather than auto

Yeah I tried that when you suggested it - didn't seem to help.
Thanks for all the help.
I've shot off an email to asus and evga - here's hoping one of them can help me out. My gut feeling is it must be some compatibility issue or motherboard issue. I can't see both EVGA cards being faulty which they would have to be given that neither worked when on it's own.

Have you tried clearing CMOS or running on bios chip 2? Doubt it will do anything but worth a try. Very odd though.
Sounds to me like its the board. Very unlikely both GPUs are dead as they will be re-tested once built up. I feel your pain, slot died on mine a while ago. Needed to RMA the board which was easy but it can be a pain especially when you've got to drain the pipes and remove everything first.
If its the latest bios shouldn't be a compatibility issues, USB is generally the best way to do it.
