R2 weird CF problem

I just changed me CPU from 720 -> 920xm

and now i've got a problem in game in crossfire , i've just recorded a short video about that, please watch, the display was shaking at the end of this video

‪Mafia II‬‏ - YouTube

I tried with Mafia II, Assassin's Creed II, AC brotherhood, in all game it behaves like in this video, sometime the display was moving, shaking
I don't know why, tried it with one card, everything is fine

Only game that doesn't have this prob is nfs shift 2, its still in normal way like before. Note before I changed CPU, everything was fine, then I don't know why, I even didn't touch the graphic card, what do you think?

thanks in advance!

P/S: I'm on 11.8 and 11.7cap1 now, tried it in 11.6 and 11.6 cap2,3 with same results

 

It looks like Microstuttering to me. What frames are you getting? Also maybe a longer video might help.

 

Are you overclocking?

 

yes, a lil' bit 5870 @810/1150

and I'm on A10, 11.8 , 11.7 cap1

I tried this in 11.6 , 11.6 cap2,3 with result

all game in 60 FPS , sometime it dropped to 50FPS

 

I'd remove any overclocks. See if it works, then work my way back up.

 

If you can try reverting to the stock clocks. That way we can see if it is your OC.

 

yeah, I try, i'm back in a few mins, thank you all

 

I'm back at stock clock but it's still there, the display is still shaking, i can make a longer video for you

 

Ok, that would be great.

 

here we go

‪Assanssin's Creed Brotherhood‬‏ - YouTube

‪AC 2‬‏ - YouTube

it happens more often in AC so I recorded in that game, you can see constant FPS in 60 and that display just vibrating and shaking, and you can see in second video, I let the guy Ezio just stand there and the screen behaves the same thing.

Edit: I tried to record it with FRAPS but the issue didn't show up there.

Looks like you got a bad secondary card


Before you call dell though try the stock dell drivers.

 

Hmm, I second microstuttering.. Double check your video drivers..

 

I'm going to check driver again to see what happen

 

Try the stock Dell ones while you are at it.

 

Yea, try different drivers first before suspecting the card. Let us know.

 

Oh man, hope you get it sorted out.

 

I had the exact same thing happen and could not fix it. All of my games would stutter when xfire was enabled....some worse than others. I tried about 5 different drivers to see if it would help but to no avail. I ended up having to RMA the graphics cards and it worked again. Just for kicks I decided to keep the original primary GPU in and install the new secondary card to see if it still happened (it did). So then I took out the old primary card and put in the new primary card and switched the secondary new card for the old one. Guess what? No problems. So in my case, my original primary card was the one causing the issues. Hopefully your m17x r2 is under warranty because I fear that one of your cards may be bad. Not the best news but hopefully this helps!

 

I tried to stock driver, it couldn't help, then I tried to reconnect crossfire cable, it work again, atleast until now. so I think its problem is that crossfire cable wasn't in right place.
I'm testing more and let you guys know, and thank you all for help!

++rep when I'm allowed

 

Awesome, hopefully that's all it was. I know the crossfire cable can be pretty problematic if not plugged in completely.

 

yes I hope it is the only problem, I don't want anything more

and it was plugged in properly but the whole cable wasn't in its old place, so when I put the keyboard on that, it was pressed and made some affection I think

BTW how about your 920xm temp? normal using, benchmark, game...?

 

Dang these minor and major issues I keep reading about Xfire makes me want to steer clear

Hope you get the issue resolved.

 

yeah, thank you, it's fine now, it was crossfire cable problem and I hope I wouldn't get another one

 

I have the exact same issue. I already called dell and they're sending someone to replace the motherboard and graphic cards along with heatsink(s). I might open it up and check on the cable just to make sure though.

 

The other issue I know about CF is that it sucked when it tried to play GTA IV haha...
