Hello everyone,

So right now i am working with;
- an i7 5820K.
- gtx 1080 in sli
- 2 Gigabyte Nvidia GTX1080 Xtreme 8GB GDDR5 PP PCI-E
- asus rampage V extreme motherboard.

I have my video cards connected on slot 1 and slot 3. Slot 1 and 2 doesnt work as it reads the pcie at x16 and the second one at x4. And slot 1 and 4 is impossible because of the psu's size.

So my problem;

I have connected the two cards via two old flexible bridges. I am experiencing instability, artifacts and crashing on several games and applications; such as Heaven benchmark, 3dMark, and black desert online.

However, on other games such as battlefield 1 and rise of the tomb raider, i have no problem at all.

Before getting these cards i was using a 3way titan x sli (non pascal) and never had any problems. Also i know that black desert supports 1080 sli as i have friends who use this set up.

I've tried a clean driver install with DDU, changing to older drivers, but still same problem. Could the culprit be the old flexibridges? I ordered an nvidia hb bridge and am hoping that it will solve the issue.

If anyone could shed some light or have some insights, i would greatly appreciate it as i don't know what else to do.

-- update:
- One of the cards may be faulty. I was testing them each on their own. One card was fine with all games and applications, the other one kept crashing on some and giving me artifacts

I upvote this a bit. You might see a little better performance in some places once you get upgraded to a more recent bridge, such as a HB bridge. Also, don't worry about a little backtrack in some games because most of them have instability issues when it comes to SLI configurations. Anyhow, good luck with your system!

I am planning to switch one of the cards with another card. This will leave me with these cards;
- 8GB Asus GTX 1080 ROG STRIX GAMING ADVANCED GDDR5X PCIe 3.0 Video Card
- Gigabyte Nvidia GTX1080 Xtreme 8GB GDDR5 PP PCI-E

I shouldn't have any problem with sli compatibility right? since one is strix and the other one not.?
Thanks
