Sabertooth X79 layout question

Is this what you are looking for?

If you still have it, the mobo manual has diagrams of the mobo and features description and locations.  Just thought I'd throw that in. 

I tried to install the 960 pro nvme via pcie card and got the "USB device over current status detected system will shut down in 15 secs" I searched the internet for a solution, but have had extreme difficulty even determining what the error means. Does anyone have any ideas? All the solutions I've found so far don't apply here. As soon as I remove the add on card, the system boots fine.

After the first error, I reseated the card and the system booting normally. I was able to install the 960 pro nvme driver from Asus and although I could see the device in device manager under (I forgot what tab) it didn't show in file manager where my other HDs are. One last thing I noticed was that at this time I observed that my USB keyboard was hanging bad on keystrokes which makes me thing it's something to do with inadequate pcie lanes for the 960 and  everything else.

I removed device and computer is normal again. I'm not going to agonize over it, but it would be nice to understand what's going on and fix it if possible.






.. fixed broken format...

The error only occurs when the nvme pcie 3.0 add on card is installed. When removed everything is normal. I only have the mouse and keyboard utilized via usb at this time. I did try to remove them and boot once, with card installed, and got the error.

I'm pretty sure I didn't damage any connectors on the MB since it works when the card is removed. It doesn't seem like an electrical issue.

Like I mentioned the one time it did boot and I was able to install the driver, the keyboard became periodically non-responsive like there was a bottleneck or something.

I was thinking about trying to disable my USB 3.0 ports in bios and try again. Do you think it's possible that this is a resource issue? I do have 2 780 tis sucking up 32 of my 40 pcie lanes. Plus the bios is the original that came with the PC. I can't upgrade for fear of losing my OC.

To be clear I only want to use this as a game drive not for OS. Do you think the disable USB 3.0 route is worth a try?

I just noticed something. The bottom pcie slot is set fro 3.0 x 8x according to the diagram of the MB. Is it possible that bios is forcing this to allocate 8x lanes to slot? I will take your advice and go into bios to see if there are any options for this slot. Do you happen to know what tab in bios to look?

I did some searching and my MB is supposed to be supported, but not as an OS drive without some additional steps. One thing I read from the Samsung manual was that you need to change the boot order priority to UEFI. I didn't do this since I've not going to boot from it, but maybe it's necessary.

One thing I wish I could solve is the exact definition of the error. It says over current, but nowhere can I confirm if it's a reference to electrical problem or a resource issue. I couldn't even find the answer to this on the Asus website. If they don't know who the hell does? I was thinking about replacing the 780ti SLI with a single 1080 ti card. If I do this I'll try the card in the #2 slot and see what happens.

Thanks for the efforts boss. Unfortunately the problems I encounter, as a rule, don't have easy fixes. :)

That’s an excellent question, but I’ve never seen the stats for a mobo listing power draw on each slot, total, usb, etc.   Not sure how to get the info but I’m gonna research it later because I’m curious.    An email to Asus engineering might be the way to go. It does make sense the new card is kicking the mobo in over current. Try remov8ng one of your 780s and see what happens. Or just disconnect the 780s power plugs.

You can leave the bridge on.

Just thinking....the mobo’s, especially the Sabertooth, are good for sli, a sound card and maybe a WiFi card.     I wouldn’t think the adapter card for m.2 draws that much, but not sure.

HAF-X is a real nice case. Wish DS still used it.    Can’t tell ya how many configs I did on these forums using HAF-X.        Airflow is not an issue.

Solved. Disabled the USB 3.0 things in bios. Enabled UEFI boot in (don't know if this was necessary) bios and system immediately booted. Of course there was the hour of frustration trying to get file manager to recognize drive. I don't know why I never remember that a new HD has to have a letter. Once I relearned this the rest was a snap. Random read is 2797 MBs and random write is 2253 MBs. Thx for the assist. It is easier talking through problems like this than going in alone.

So you didn't need an adapter? That is nice

Congratulations great job
