I'm using a GTX 970 SLI and I do not understand why my results came up like this:

https://scontent-lga1-1.xx.fbcdn.net/hphotos-xta1/t31.0-8/11357313_10205308010154627_8472570323993770729_o.jpg

This is in 1440p resolution as I am using the ASUS ROG Swift PG278Q

Specs:
i7 960 (Overclocked to 4.0 GHz)
MSI x58 PRO-E
GTX 970
GTX 970
12GB DDR3 1066MHz
Corsair H80i
Corsair 850W Gold

The last two baselines are other computers using a SINGLE GTX 970
The 6th baseline uses a Single GTX 980

Why does my score appear as that?

UPDATE:
I have also used the 3dMark 11 - Performance and my Dual videocards score 9311 ONLY, while other people using a single GTX 970 score in between 15000 and 16000.

My Score: http://www.3dmark.com/3dm11/9839331
Similar User's Score (With same CPU, GPU SLI, Memory): http://www.3dmark.com/3dm11/8965971
Another user with same setup: http://www.3dmark.com/3dm11/9046776

All of them using GTX 970 SLIs are in between 25,500 and 26,500 while mine is 9322

Note: I am using the ASUS ROG Swift PG278Q Monitor

In SLI the two cards are as fast as the slowest card, so that would explain some of the performance hit. try to get the second card up to the speed of the first card. try that and see what happens, also try boosting the voltages by about 5mv or perhaps even 10mv, that will not be enough to cause any damage, and should not even produce much more heat, but it may stabilize the cards.

Thank you for your thoughts. I am, however, new to SLI and overclocking and that is something I am still familiarizing. However, yes my motherboard is quite outdated, but is still running a PCI-E 16. Not sure about the SLI bridge issue/compatibilities since all I did was buy a bridge for 30 dollars and made sure it worked with the appropriate softwares. Benchmarks recognized SLI configuration as well as games.

What's even more annoying was that a single 970 scored higher (10000-11000) than my current SLI setupd (9322).

what is your second PCIE slot running at? some can dip as low as X2 if other device are drawing PCIE lanes. and SLI needs dual PCIE 2.0 or better at atleast 8X. that could explain it, is there any way you can test in a friends computer or as some local tech shop? You motioned overclocking, what are you GPUs running at? also is the overclock stable? if it is not fully stable, it could be struggling to run the benchmark.

My motherboard according to specifications have PCIE 2.0 16x. I am thinking if buying a new set of processor and motherboard would solve this problem, but the other users are using the same processors like mine. I am a newbie in terms of overclocking and SLI. First card is 1250mhz 1.220v. Second card is at 899 to 999mhz at 1.080-1.150v. I know that there are 2 way SLI users who are facing undervoltage issues and underclock issues however I do not have enough knowledge to solve this complexity.
