I've read a couple of reviews saying the 6900 XT has large power usage spikes - in LTT's video review he mentions even having to switch out their Seasonic 1000W PSU as the OCP kept getting tripped.

Has anyone run into any power related problems? I have an 850W version of this: https://seasonic.com/prime-ultra-titanium so wondering if I might run into the same issue that Linus did...

5 year old XFX 850 Gold here. No problems at all and I like to push my card. I haven't heard of any 6900 XT owners on these forums reporting any such problems. Heard of a few 3090s behaving like that though...

Everyone must be settled in with there new 6900Xt’s.

Thread seems a bit quiet these days.

Yep, using a 2300Mhz/2012Mhz clock profile here which is more than fast enough for my games and have the GPU running at only 0.975v.

Draws around 225W under heavy load according to HWINFO64 PPT metric.

Probably because they’re impossible to buy. I’m waiting to get one but have only seen the Red Devil one come up which is too big for my case. I’m waiting on the Sapphire Nitro+.

Nice, what temps are you seeing under load, Hot Spot/GPU at that voltage/clocks/Power draw?..

Is that with your XFX Merc?.

Yes the Merc, cooler is beastly.

I think temps get up to around 75c on Edge and around 85c on Junction, with the fan speed at just 24%. They are barely moving.

Haha, maybe I can help a little - @Kaapstad can you TROH me up please?

Bit confused about why this key cap is so much larger than my others... guess I won't be using it!!

Cheers,

Su

I'm running my 6900XT on an ROG Thor 850w which I think is based on a similar Seasonic PSU and it's been fine so far in Cyberpunk.

Yes performance wise there isn't a lot to say, Cyberpunk being about the only game it can't run max setting at 4K. I had my card mount vertically for a week but it was a bit too in your face for me. It was a bit like having a bright green or orange Ford Focus ST when I'd rather have something for subtle, lie a Alfa Romeo Giulia Quadrifoglio.

Here are some pics of the card mounted both ways:

I think ultimately, it was the fins at the end of the card that swung it for me. They look awesome horizontally but vertically, they are kind of misshapen and look more like bars.

Lovely! Is that the Hyper X keyboard? My keys have worn exactly like yours, been wondering if you can buy replacements recently...

While we're sharing pictures, I swapped cards around and decided to stick my 6900xt in my main rig.

Waiting on extension cables to tidy up the power cable situation

Oh yeah! Much nicer looking than the 3090. Stunning.

Looks nice that Mike.

Thanks chaps, I'm really liking the config this way.

It seems like the two machines are fairly balanced performance wise, too!

Good stuff.

Now try running Firestrike Standard, Extreme, and Ultra (4K) and compare performance.

Just pulled the trigger on a custom build with a 6900XT last one they had. I wanted to build my own but no hope in finding cards anywhere. Can’t wait to get going, coming from an older Alienware 17 with 880m... will be epic

Sweet man, throw up some pics when you get it all settled in

Haha, I guess the 6900xt had to win something

Chaps, having an annoying problem with the new card and my monitor...

Every time the monitor wakes up from power saving mode, the resolution drops to 1280x800 (maximum available to select in Windows). I need to turn it off and back on again for it to get back to 3440x1440. This didn't happen with my old Vega 64, so I assume it's a 6x00 series "bug". Monitor is an LG 34GK950F-B.

Any ideas what setting(s) I might need to tinker with? in either Windows or Radeon control panel?

It's a Drevo Blademaster, but I've put the textured Corsair FPS keys on there! But yeah they have worn out pretty badly, so I should probably get some replacements...

Nice! You will love it
