SLI soround problem GTX 1080

[Majsterek]

Hey so im runing 3x 1080 p sourund sli setup . 

 

But i have a problem with the clock speeds . 

 

One of them has led and it is overclocked both are from the same manufacture . They are running at different speed since one of them is factory overclocked . 

 

I know that when i run haven benchamrk i can see one of them is running little faster cloc speed . I think this is making some weard lags and fps drops . 

 

all of the monitors ale conected to the bottom card

Only time I’ve had a difference in clock speed was from something not keeping up. 

 

Like if my cpu is struggling, one of my cars will drop. Or both will drop equally. 

 

Are you using nvidia surround for it?

 

The benchmark is prolly single thread bound and causing this issue.

The benchmark is good , somtimes just freses for a split second or fps drops and one of the cards stops working then turns backs on . also Navidia panel shows the activity of cards seperetly .

You can see them runing at different cloc speeds and also one of them is not runing anything

Doesn’t really asnwer anything I asked though.

I found out that i have to flush the bios of the cards. One is RGB and has a different bios version therefore the clock speeds differe slightliy. 

 

anyone knows a good wah how to flash this ?

Clock speeds don’t have to be the same if the usage isn’t high enough for the second card. 
 

Unless you have ran a proper benchmark to ensure the usage for both are at 99% and the clocks speeds aren’t matched there, can’t say that the bios is the issue.
