The high multi-monitor power draw issue affected RDNA2 for some in early driver releases but they managed to iron it out so I expect the same here.

It's a known issue for sure atm on RDNA3.

Okay, try these settings for now. Leave your fan profile as is.

Put power limit to 0%. Set core voltage to 1050. Leave the min core clock at 500Mhz. Leave the max core clock at 2.9Ghz, if this works out later you can try increasing it to 3Ghz. Set the memory to Fast Timings enabled and 2700Mhz and test. If you get flickering/flashing while gaming, reduce memory to 2650Mhz and retest.

Crashes in Witcher with those settings, so it’s probably just the game?

Prior to the crash the junction temp was around 65’c

Probably means too few voltage. Try memory at 2650 and GPU voltage at 1075 and retest.

The VRAM does not always downclock on 6900xt with multi displays, most drivers are ok though, not had it in 4-5 updates.

That worked.

Thank you very much for the help!

Cool, keep testing. Can always try bumping the memory up another 25-50Mhz.

Has anyone managed to get a solid 60 in Witcher with rt at 3440x1440, what about cyberpunk, what are the best setting to play that with some of the rays on? (only two games that I’m botched about with RT)

Yeah, I still have the issue depending on the refresh rate of my screens, but I rarely have the second switched on sonl it's not a big problem. Also had the same thing intermittently with my 1080 Ti on certain drivers.

Stick FSR 2 on perf and you should be good. Witcher with RT gets massively CPU bottlenecked in places though so if in cities/towns it drops below 60 don't be surprised, GPU use will drop and one/two CPU cores will get maxed. Seems to be a game bug where it isn't distributing the cpu load over all the cores like cyberpunk does etc.

My XT got shipped fingers crossed I get it tomorrow

Would swapping from a 5800x3d to AM5 be worth it?

Doubtful - personally I would wait and see what the new x3d parts are like, they should bring tangible benefits.

 

[LtMatt]

Yes, 100% yes. Warzone loves 3DVCache, I say this as a person who had a 5800X3D on Warzone with a 6900 XT and later a 6950 XT. If you get a 5800X3D, a 6900 XT/6950 XT would be a perfect match.

Just read the comments.

EDIT - Let me edit my post slightly as I didn't realise you were already on 5800X3D.

Swapping to AM5 from (AM4) 3DVCache would only be worth it if you swap to a Ryzen 7000 series that features VCache. Then it will be worth it! @Kali81

Unreal Tournament 3 at 4k, 400fps! Skyrim at a constant 60fps without having to turn ENB settings down! I can actually run Quake 2 RTX now!

Some coil whine at high frame rates, but far from the worst I've heard.

High idle power. From the recent driver release notes I was hoping a workaround would be to set the refresh rate to 60Hz for both monitors, but unfortunately it only goes down if I both set the refresh rate to 60Hz and disable Windows HDR. Hopefully it won't take too long for AMD to fix it.

...please make sure to post the stock max frequency core clock your sample comes with...

I checked immediately after installing the card and it said 3140MHz. I checked again before posting this, and it now says 3080MHz.

Oof, 3140Mhz, that’s higher than mine which also varies but peaks at 3105Mhz.

Has anyone tried Red Dead Redemption 2 with the 7900 XTX? Game runs insanely fast and is beating my 4090 at 4K max settings (MSAA off).

This makes me a happy..

Me too. One game I’m going to play through again with this card.
