Weird, I have the same motherboard but I don't have the same experience.




Are using native windows 8 mode or using CSM ?







Are you talking about in the BIOS? There is a setting in the BIOS that ask if you are using windows 8 and I selected it, I didn't change any fo the default values because I was undure what all they did and I figured  the default would just work....


The operating system is Windows 8.1 Enterprise (n edition).


How is your experience differing from mine? Are you still experiencing the sound stutters? Are you experiencing the wierd frame rates that others are talking about?


I purchased my cards March 8th from NewEgg and I'm still in my 30 day window. If these cards wind up being buggy they're going back... I still have to test my games in eyefinity and I have a bunch of games to test...


One thing I did notice though, when watching a DVD or BluRay, the sound is a little off. Not the stuttering, but it sound like I turned "reverberation" up just a tad...... 


Also,  one more thing to mention seeing as how you have the same setup, when I did my install, at first the sound wasn't working... Everything looked like it was installed, all the volume indicators appeared as if they were playing sound, but I wasn't hearing anything.... So, I figured I'd try reinstalling the drivers, well, when I uninstalled the drivers and rebooted, my PC installed Microsoft HD audio drivers on it's own and they appear to work just fine. 


BTW, I am getting true stutter free HD 7.1 audio with this MS driver.



Yes, I am getting this weird frame rate that others are talking about...I might reinstall windows to see if that fixes this problem.

Reinstalling didn't fix it for me, nor did switching to Windows 8.1. I'm back to 7 now and after two reinstalls the problem remains. I did note that it didn't affect Thief when Mantle was enabled. It only seems to affect DX games.

EDIT: Talking about the FPS issue. Audio works fine.

For me the problem persists ins certain games. Some it became somewhat better (but not completely dissappeared) others like IL2 Battle of Stalingrad the problem persists. Its a Direct X 9 title and activating crossfire with enabled VSync makes the sound stutter every few seconds. This really needs adressing. I bought graphiccards for more than 1000 euros just to NOT being able to use them properly. One thing is a fact now (at least for me) NEVER again AMD when it comes to graphicscards. I didnt ever experience such gamebreakers during my time with NVIDIA graphicscards.

Some people report that re-installing the chipset driver suite replaces the missing drivers. 8 - 32


I am using an Intel platform. Gigabyte G1 Sniper 5 (Intel Z87) with i7 3770k. And yes, I do believe that reinstalling chipset drivers would indeed fix the issue, but as I was unable to use *any* input device (no mouse, no keyboard)  I obviously could not do it the easy way. Of course it is possible to do it the hard way - by running a system repair or manually injecting the usb drivers after booting from a different system; but knowing AMD drivers and their undying residue, its a safer bet to just reinstall the whole system

Be as it may, this is not the topic; however nasty the tool is, the fuss it makes it pales in comparison with the issues that R290 crossfire makes. Mostly because it is fixable - which cannot be said for 290 CF yet
