Upgraded to 780 TI SLI and having freezing problems, help please

I've already posted about this before about a week ago, I'm just gonna repost an updated version. 

System Specs:

i5 4670k 4.6ghz 

gtx 780 Ti classified SLI

asus maximus vi formula

16gb ddr3 1600

Corsair ax860

samsung 840 evo 250gb // WD caviar black 1 TB

1440p display @ 110hz 

 

 I upgraded from a 4gb gtx 670 SC to 2 gtx 780 ti classfieds. I have been having freezing problems in battlefield 4 ever since. Just a freeze that lasts around 5 seconds usually.(1 of them resulted in a BSOD). They seem to happen randomly. I can go 30 minutes without a freeze, or It can freeze like 10 times in a single match.  Just gonna throw it out there, dont try and say its because BF4 has alot of issues, Im aware of them. I've never had this problem prior to putting these cards in. I also tried Tomb Raider, it froze after about 30 min and I had to hard reset. The cards were not OC'd. I've done a good amount of troubleshooting and have somewhat hit a wall, I don't know what else to try. Ill try to explain all my trouble shooting I've done as detailed as I can

 

I tried disabling SLI, that failed. 

Then I tried uninstalling all nvidia software and then running driver sweeper in safemode and reinstalling fresh drivers(still using SLI), that failed. 

I then took out the bottom card and just used 1 card(I also rolled back 1 driver version when I did this). this failed as well. 

 

Next I just swapped cards(still using 1 card). This is where things get weird. So now I'm using 1 card, and its the card that was originally the bottom card. Playing BF4 for about 2, maybe 3 hours and no freezing at all. I'm thinking hell yea the other card is just a defective card and that's an easy replacement. I wanted to be thorough with my trouble shooting so me and my friend decided to make him a guinea pig. We put the card that we thought was defective into his computer. He has a similar set up to mine. He played for around 5 hours maybe more and not any single indication of any problems on his system. This worried me so I decided I just need to test mine out more. I get on BF4 and it freezes right away, and it starts freezing more frequently after that. I turned off my OC on my cpu so its stock. No change at all still freezing frequently. Im somewhat at a loss of what to do now. I was hoping that the cards were just defective because that's an easy fix. But that doesn't seem like its the case since the original card worked fine in a different system.

Sorry about the length of this post I tried to be as detailed as I could. I apologize if I left out any details that would be helpful, let me know if you need to know anymore information.  Anything helps even if its a hunch I'm open to try just about anything thanks.

 

Sorry to hear you are still at no end of solving this tech riddle.

Sounds like you have ruled out one of the gpu's being faulty which is a relief. Which leaves just the motherboard, psu or even the cpu being at fault. 

  • Which pcie x16 are you using? 1 &2, 1&3 or 2&3?. Try all combos.
  • What is your BIOS version - 1402? if not then try updating it.
  • Run a linux distro and the heaven benchmark to rule out windows as being the culprit.
  • If you can try your psu on your mates pc with both cards, no problems then psu is ruled out as being at fault.
  • Send an email with details to ROG themselves. They may be able to shed some light on the issue.
  • RMA the board as a last resort before banging one's head against a wall.

 

for sli I used 1&2, i didnt have a long enough SLI bridge for 1&3. For single gpu testing I've used slot 1. 

looks like by bios version is 1302 from december

SLI won't work in 1 & 3 anyway. That 3rd slot is x4 only and you need at least x8 for SLI.

That being said, all the other advice in this post is sound. Keep tinkering with it and you'll eventually find the solution.

have you tried reinstalling windows?

Kind of saving that as a last resort

I've never done this so I figured Ill ask. Could I put another HDD into my system to install another os onto and boot off of that and still be able to revert back to my current OS? Or would I have to put in a HDD with an os already on it? 

you can totally install a fresh harddrive to install another OS, same process of installing an OS. if you are talking about dual booting that's another thing.  but for testing purposes you can do what you outlined and then you can just put the old hd back in if you want to run your old OS again.
