| Post subject: | OMG. If this is true I love |
OMG. If this is true I love you. Are we saying that if I swap out my i5CPU for a phenom, the crappy crappy Crossfinity crappiness will go away? I think that would be cheaper than selling my 6850s and upgrading to a better single card set-up. Can anyone confirm that AMD CPUs are really the fix? It seems too good and too simple to be true. This issue has been an ache in my soul ever since I put this my dream machine together.... sob..... To add to the picture of consensus: I have: 2x 6850 i5 quad@ 3.3GH and eyefinity blows on all games. I think the latest driver just straight up turns off crossfire when you launch games which to me is hilarious. |

| Post subject: | There is a setting in W7 |
There is a setting in W7 power management. Under PCI- Express "Link State Power Management". Wonder if that effects anything. I am 100% convinced that this is somehow related to the sub-system of the PCI-E bus, or the way the cards swap info across the PCI-E bus, and not a driver problem. Although, I don't have anything I can test with, my 939 system is in England, and I have just sold my CPU (E8400) from my 775 system. That would of given some interesting points of comparison anyway! There is a very slight chance I could get my hands on an older, and a newer AMD system, a 4 core and 6 core phenom. Must speak to the GF's cousins! |

"Link State Power Management". Wonder if that effects anything. Already tried changing that setting, but the problem is still there. There is a very slight chance I could get my hands on an older, and a newer AMD system, a 4 core and 6 core phenom. Must speak to the GF's cousins! If you can somehow test this theory, it would help me and others that are having the same problem a lot. I would like to be testing myself, but would have to buy an amd cpu + board, because nobody I know has a AMD board which supports crossfire/sli. |

| Post subject: | Maybe we could make a list |
Maybe we could make a list here to see who has that micro stuttering and on what config and what drivers: So for Bushmaster it is (if I have it wrong just let me know): No stutter: intel q 9300 - AMD 6970 x2 - driver ? i7 2600k - Nvidia 460 x2 - driver ? Phenom x 6 - Nvidia 460 x2 - driver ? Phenom x 6 - AMD 6970 x2 - driver ? Micro Stutter: i7 2600k - AMD 6970 x2 - driver ? |

| Post subject: | Had to register |
I have been using this forum for awhile trying to find solutions. I have read a lot of people thinking that it seems to be only Sandy bridge CPU's causing the crossfinity microstutter... I felt I had to register after reading to tell you the bad news. in my situation I am using 100% amd platform sabertooth 990FX mobo, 2x 6950, and an AMD FX 8150 (used to be phenom II 965) both CPU's produce microstutter when using crossfire or eyefinity. seems I can use only 1 or the other. updated my bios, drivers, everything. never found a solution... just letting you guys know before you go buy a phenom or bulldozer that it probably won't fix the issue unfortunately. |

| Post subject: | Bushmaster, I thought I was |
Bushmaster, I thought I was the only one having issues with my Asrock z68 extreme 7 board, like you I have massive stuttering when I use my 6950s in crossfire mode. Tried every thing you have done to fix the issue and can not for the life of me find a solution. So I ended up buying gtx 580s to do sli guess what? The Nvidia cards worked like a charm go figure! |

| Post subject: | wow,I just read all of the |
wow, I just read all of the posts since my last post. I sympathize , relate and understand all of you that have replied to this post. There are a few posts that I feel are questionable or that I disagree with however there is only ONE in particular that I will quote because I have completely proved wrong. First. I would like to say... I build my new system Friday night. Asus Crosshair V Premium, with a 1100t . I am still using the same 8 GB of Corsair XMS 3 1600 mhz Ram. In fact the only thing that has changed on my system has been my MOBO, and CPU. This WAS, the first weekend that I spend PLAYING games on crossfire and Eyefinity rather than tweaking settings and trying to decide whether my system sucks or not. ALl of my games Run smooth on Eyefinity now, and VSYNC works 100 % with this setup. I was initially going to post some videos for you guys of how the system plays games. I took a few videos of BF3 and will post them shortly. I will also Post Dirt 3. Both games run awesome. BF3 was unplayable before with crossfire and Eyefinity. I have been using this forum for awhile trying to find solutions. I have read a lot of people thinking that it seems to be only Sandy bridge CPU's causing the crossfinity microstutter... I felt I had to register after reading to tell you the bad news. in my situation I am using 100% amd platform sabertooth 990FX mobo, 2x 6950, and an AMD FX 8150 (used to be phenom II 965) both CPU's produce microstutter when using crossfire or eyefinity. seems I can use only 1 or the other. updated my bios, drivers, everything. never found a solution... just letting you guys know before you go buy a phenom or bulldozer that it probably won't fix the issue unfortunately. As for this quote. I have not read this anywhere else. I searched for about 4 days in a row looking for a resolution to my problem .. I NEVER read anyone mention that the problem is that you need to run AMD cards on an AMD system ( I dont even believe that this is 100% true.. I think its a sandy bridge and AMD issue) Regardless of your comment. I proved that this works 2 times now. Once on my friends system, and now on my own. AND the ironic thing is.. I NEVER believed that this was gonna work! I was going to sell these 6970s to spend more money on gtx 590s ( one at a time of course) ... gonna go post these videos on YouTube now or something so you guys can have a visual.. edit: btw my system does run 5760x1080 ... as you may recall the original testbed on my friends amd ran 5400x1050(or whatver). |

| Post subject: | I have HAD microstutter |
I have HAD microstutter before, but have been able to solve it in all games except skyrim. My system is a Phenom2 x4 and Radeon 6850 x2, with Gigabyte 16x/8x (8x/8x crossfire) In witcher 2, I was crossfired, playing on ultra at 1920x1080 and had intermittent MS. Interestingly, I noticed the board's GPU (radeon 3xxx) was enabled even though not used. Updating drivers and disabling it eliminated microstutter. My opinion is that MS is not a foregone conclusion and is related to device conflicts, sharing, or interrupts. These may be difficult or impossible to track down in some system configurations. Also, I did not know there was a MOBO that could run both SLI and crossfire? Maybe that was the original posters problem, that his board was not an official CF board. |

Dude as of 3 or more years ago most of them support both... Find me one made within the past 24 months that doesn't support both... They all do now a days. |
