How's it been on the temps. I received mine mid Dec I think but was finding on Performance BIOS (default) and out of the box settings it was hitting 110 and above on the hot spot quickly running Far Cry 6 or after 1 or 2 runs on 3D Mark which was obviously throttling the card. Running an RM850X with three seperate PCI-e cables. Had to switch to Quiet BIOS which kept the temps (Hot Spot) around 100 but not had much chance to mess about it over the last fortnight with xmas and in the middle of adding new mobo and CPU to the system. Got all that sorted with a fresh Windows 11 install over the weekend, so tonight I'm going to have another try tonight but surely temps like that aren't normal running standard settings. I did try undervolting and altering the default fan curve (what a pile of crap that is) but surely you shouldn't have to do that running default settings on default clocks. Case temps and CPU temps have been fine and this is without the side panel on, just not sure if there's a problem with the card, especially seeing the problems with heat regarding the 7900 series.

If you are hitting 110C with 6900XT Asrock Formula? It's got a very bad factory mount. I'd give CS a call and get it swapped.

Yep, ASRock Formula Extreme. I will it give it a whirl later to see how it performs heat wise in my new Z690 board, was running a Z370 carbon previously. If not then I'll have to get onto CS.
 
I've had quick play with the fan curve and tbh apart from disabling zero fan it runs quite well. I gave P3 and P4 a small +3% increase which equates to about +168RPM bump. I must be getting old as I can't hear the fans. :p I decided to turn zero rpm mode off as 1. I can't hear them running anyway at ~880 RPM. 2. I don't like the idea of a warm-ish brick at ~40ºC sitting inside the box just heating other components up around it. 3. With zero rpm disabled the card now idles between 27-30ºC. I'd rather have the heat expelled from the case with the fans just ticking along. I saw no difference in power draw with zero rpm mode enabled/disabled.
 
I don't seem to have seen any media around the XFX Merc 319 6950XT and was hoping that was going to address my issues but no-one else seems to have one on the internet :). Ever since I swapped from my 3070 I cannot play youtube on my second monitor while gaming monitor without stuttering on the video or both depending on the game. This is with Hardware accelartion on or off, Has anybody else fixed this issue?

I just RMA'd my red devil 6900xt for constant white static crashes and immediate crash on game open if apply ANY changes in AMD tuning ( even just changing power level 1%) . Does anyone know the RMA process/ options , ie Im assuming they find the same faults but if they say its fine can I just decide to return it under unwanted item anyway rather than them post it back? I'd have no reason to think it would magically start working for me. The only thing I havent tried is diff PSU but unlikely brand new toughpower 850W PSU is to blame.. and id rather to not shell out £200 for a 1000W psu to have that confirmed!

You using the latest driver? I know there has been some issues with multiple displays and high refresh rates. Anywho, this is the latest Fixed/Known issues from AMD.

Fixed Issues​

  • During video playback and window switching, an intermittent driver timeout or black screen may occur on Radeon™ RX 6000 series GPUs using some 240Hz refresh rate displays or high refresh rate primary display plus low refresh rate secondary display configurations.
  • Stuttering may occur during video playback using hardware acceleration with Firefox on Radeon™ RX 6000 series GPUs.
  • AMDRSServ.exe may cause GPU utilization to remain at 100% after closing games on some AMD Graphics Products such as Radeon™ 570.
  • An intermittent driver timeout or black screen may occur while videos are playing in VRChat™ on Radeon™ RX 6000 series GPUs.

Known Issues​

  • Intermittent system stuttering or UI flickering may occur when two videos are simultaneously playing using chromium-based browsers.
  • During video playback and gameplay, frame drop may occur in chromium-based browsers with variable refresh rate enabled extended displays.
  • Brief display corruption may occur when switching between video and game windows on some AMD Graphics Products such as the Radeon™ RX 6700 XT.
  • Texture flickering or artifacts may occur during Warhammer 40,000: Darktide™ gameplay.
  • Some laptops using hybrid graphics and AMD Ryzen™ 5000 series Processors with Radeon™ Graphics may have no sound output using certain Realtek Audio versions.

Of course I am using Chrome, abit of a pain but I will switch to firefox tonight and hope for the best, does anyone have any other browser recommendations that arent Chromium based?

I am on the latest driver (22.11.2), does anybody have an estimated timeframe on a new driver release?

Thanks for the quick response.

@keithcun yeah not hitting those temps at all. I think I was seeing mid 60s for gpu and hot-spot was about 10° higher. I gave it a quick blast in NFS Unbound and Callisto Protocol.

Well, just finished installing usual stuff on new system and ran default 3D Mark Speedway three times. Running default settings on Performance BIOS which is default setting. PC was cool, ambient temperature about 17degrees (heating hadn't kicked in yet) and first run hit 108 degrees and Hotspot and over three runs Hotspot hit a high of 112 degrees and GPU hit a high of 97 degrees. Max Power Draw was 327W. Highest clock speed of 2628 MHz and Mem 2220 MHz. Ambient temp in PC case was 25 degrees after the 3 runs so nothing abnormal there, plenty of air flow through the case even with side panel off.
Think I'll have to go with RMA as not keen on repasting a month old card, if that's the problem, nowhere near as brave as some folk on here. ;)

Give FF a go yeah. Fingers crossed. I use FF and really like it. :)

Doesn't sound right does it. :(
 
RMA'd my card this morning due to the overheating issue and hopefully get a replacement after OCUK have verified the problem as it seems to be a great card even though I couldn't hit it's potential due to overheating.
