Introduction and Technical Specifications

Introduction
In our previous article here, we demonstrated how to mod the EVGA GTX 970 SC ACX 2.0 video card to get higher performance and significantly lower running temps. Now we decided to take two of these custom modded EVGA GTX 970 cards to see how well they perform in an SLI configuration. ASUS was kind enough to supply us with one of their newly introduced ROG Enthusiast SLI Bridges for our experiments.

For the purposes of running the two EVGA GTX 970 SC ACX 2.0 video cards in SLI, we chose to use the 3-way variant of ASUS' ROG Enthusiast SLI Bridge so that we could run the tests with full 16x bandwidth across both cards (with the cards in PCIe 3.0 x16 slots 1 and 3 in our test board). This customized SLI adapter features a powered red-colored ROG logo embedded in its brushed aluminum upper surface. The adapter supports 2-way and 3-way SLI in a variety of board configurations.

ASUS offers their ROG Enthusiast SLI Bridge in 3 sizes for various variations on 2-way, 3-way, and 4-way SLI configurations. All bridges feature the top brushed-aluminum cap with embedded glowing ROG logo.

The smallest bridge supports 2-way SLI configurations with either a two or three slot separation. The middle sized bridge supports up to a 3-way SLI configuration with a two slot separation required between each card. The largest bridge support up to a 4-way SLI configuration, also requiring a two slot separation between each card used.

Is this native advertising or why did you test an SLI bridge?? It’s like testing a USB cable.. You only notice if it’s completely broken.
The SLI bridge was not the
The SLI bridge was not the only thing tested. If you read through the entire article, you would see that a good portion of the article is testing the performance of the GTX 970 cards in SLI.
Thanks…

Does anyone know when the SLI
Does anyone know when the SLI bridges will actually be available to purchase at normal retail prices? All I’ve been able to find is random units popping up from shady vendors on Ebay or Amazon that mark them up +$100.

I like the sleek and simplicity over EVGA ugly ass SLI bridges

I recently got the EVGA 2.0 3-way SLI bridge, and though it looks great, it didn’t fit on my triple XS-PC watercooled cards without a bit of modification. The metal plate over the top was hitting the card inlet/outlet ports. It was rather unfortunate. I should probably return it for an ASUS one that would fit a lot easier.
Matter of taste and personal
Matter of taste and personal preferences. I would never, out of my free will, put anything red in my rig. That’s why if I need SLI bridge I will get EVGA not the ASUS.
And I find EVGA bridges more interesting to look at that ASUS. But we are back at the beginning. A matter of taste and personal preferences.

EVGA is obnoxious when it comes to branding on every piece of EVGA hardware from every direction even more so when lit up.

Asus is just a symbol and you can mod the light to any color

With a 780 sli setup and windows 10 with all drivers past 350.12 has a directX error “out of memory” playing battlefield 4. No error with sli disabled. 200 fps with 350.12, compared to 120fps with any driver past 350.12. But windows 10 keeps auto updating me to the newest driver that doesn’t work. 353.30 works great with single card but sli has to be disabled in order for me to play battlefield 4.
Terrible drivers with directX 12 in it.
Morry should try 350.12
Morry should try 350.12 drivers and see if the difference is large.
Morry Thanks for the
Morry Thanks for the article.I have a water cooled 5960x with 2 Sapphire Tri-X R9 290s with EK blocks. My cpu is at 4.4Ghz (44×10) using the Asus Suite III OCing software that sets the bios parameters. With both GPUs stock (1000/1300) my Firestrike scores are Overall: 17042;Graphic 21683;Physics 20,391 and Combined 5986
Overclocking the GPUS to 1125core/1425 mem yields the following: Overall 19099;Graphics 24317; Physics 20938 and combined 6968
Is it me or is multi gpu
Is it me or is multi gpu scaling getting worse i could have sworn that dual sli scaling with Kepler was much higher across the board

SLI bridges are so retro. When will Nvidia follow AMDs lead and eliminate them? Oh wait just one more thing to nickle and dime gamers.

Buy a better GPU instead, idiots.
