Tried updating the newest 780i BIOS?
EDIT: Ninja'd
Try that and if it doesn't improve performance you could go to the EVGA forum. They are pretty good when it comes to BIOS versions for their boards.
Some Firmwares are worse than the older in some boards.
Follow these steps on their website. Painless update.

CD Method (Blank CD and CD Rewritable Drive Required)
* Download the following .iso file: E178_SZ17.iso
* Use a CD Burning software to burn the .iso image onto a blank CD (Nero, Alochol 120%, etc)
* Restart machine, and set the CD Drive as the primary boot device
* The BIOS flash process will begin, Press �Y� to program BIOS
* After flash remove the CD, power off PC Completely
* Turn on the PC and load defaults in BIOS
After reading the OP, I was curious how many GFLOPS my e5400 is putting out on my 780i, and it is also low I believe, about 14 GFLOPS @ 3.6Ghz. Should be more than that at stock speeds I am pretty sure. Maybe there is some type of issue with 780i and IBT? I am worried now as well, and hope you figure this out.
my i7 870 only produces 28g flops at 4.2ghz , only on standard test cos i have 32bit system ... but my flops should definatly be mountains over yours , this is a problem.

Try other stress tests to verify if it is stable. just because it passes one doesnt mean you are stable. Could be that you need to up the NB voltage to maintain stability.
1.45V seems a little high for only a 1GHz increase. As Pio stated before your RAM has a lot to do with it as well. Sounds like an unstable OC to me

=/ I don't think it's unstable. Let me test for 100 Passes. I'll get back to you in a few hours once it passes.
Just so you understand the scaling of this chip:
3.2GHz at 1.2875
3.4GHz at 1.40v
3.6GHz at 1.45v
I could prolly lower the 3.4GHz one, but it makes no difference if it's stable.
I just tried LinX, same GFLOPs, if not lower.
