Thank you man!

Been owner of this card for about two weeks. At first it almost gave me a heart attack
I bought this one brand new but from some guy on the local forum. I ran Time Spy during which PC shutdown and happened with all benchmarks.
Turns out 850W Gold PSU is not enough due to power spikes, swapped with 1000W Platinum by be quiet! and issue was fixed.
Waiting for some cold nights to arrange some overclocking sessions So far 24k GPU score in Time Spy

Been going through this topic to find some tips on MPT usage for this model but while doing so, decided to post here as well.

Wow, what PSU was that? My 6900 XT Liquid Devil Ultimate has been 100% stable on my Corsair SF750 - and that's an SFX PSU, so it has smaller bulk caps than most ATX PSUs and should thus be at least somewhat worse at handling transient load spikes. Though I've heard of a lot of odd behaviour with newer GPUs from both brands.

I would have never thought that EVGA 850GA Gold was not enough, but that was it, as I saw TPU's review where was mentioned aboute power spikes up to 600W+ with 6900XT.
Your 6900XT was paired with Ryzen 5 or 7, right?

A 5800X, yes. What cpu are you using?

 

[Fatal Fighter]

A 5800X, yes. What cpu are you using?

5950X
There is some chart, idk how accurate is it overall but definitely was accurate for my case.
Gigabyte-s website recommends 900W PSU as well, but still I was not believing that for a very long time

Yeah, I've seen that before. I don't think the CPU has much of an effect though, at least on the AMD side - 5800X, 5900X and 5950X have the exact same power limits after all, and the higher end chips are typically better binned, meaning they consume less power per core and thread under the same load (except in very low threaded workloads where the 5900X and 5950X consume 2-3W more per core due to their higher clocks) . And CPUs don't cause that many load spikes. One difference might be that the faster CPU is letting the GPU run more free, causing it to spike more dramatically, though I wouldn't expect that to be true in all workloads. I'm quite surprised by this, tbh.

That can be true in an absolute sense, as in, however crappy a PSU is, if it can push that amount, its "safe", and even then not always correct.
Its not true in the sense that people always say "buy a quality PSU", if one has a good PSU, you deffo wont need a 100W to drive a 6900XT (350w max) plus a 5950x (150w max).
But some people either don't know or forget that a PSU degrades over time, you might have had a 750w that worked fine 3 years ago when you bought it, but today that will not be the same anymore. And there are soooo many cases where a PSU advertises lets say 750w, but can not push more than 350w sustained without problems, you would be amazed how many of those are on the market, including some known brands, though the difference is not that extreme vs crappy cheap PSU's.

Glad you found a solution to your problem, in this day and age buying a top tier GPU, then seeing it not work properly must be a very nasty experience.

I still cant believe that EVGA 850GA Gold was not enough or had idk some kind of incompatability? lol. It was a brand new PSU and RX6800 was running without any issues at all
I guess it could not handle spikes, but on the other hand I have seen builds with 750W PSUs with no issues whatsoever

Thank you for kind words!

'Grats on the purchase, and welcome to the club! Good to see more and more users/owners of AMD cards!

Thanks mate! I feel like I am going to stick around

Now, let's start overclocking that baby.

Are you serious? I got a red devil 6900xt with a Seasonic 750W and it is rock solid and stable with the card. No issues whatsoever.
Grats on the card and how much did you throw for the card if you can say? Just want to compare to what I had to throw at it in Feb.

Trust me, I am as surprised as you are and thats why the main suspect was the GPU itself for along time, untill I plugged another PSU just for the card and it worked even OC'd
I sold my RX6800 roughly for $1400 and bought this one for ~$2000

Mine is happy with 850W.

I had similar problem with my Vega64 with the Corsair AXi 760W. Bought the 5600xt (vega got damaged) and also had a problem with the new card. Switched the PSU to seasonic and all problems went away.

And I thought the 6900xt had the same 300W power profile as the 6800XT...

For the AMD reference design yes, this is correct but OEM´s can and will usually set higher power limits then the reference design.

This, plus more CUs adjusting their clocks on the fly = chance of higher transients.

I was thinking maybe its faulty PSU but damn it, OC'd RX6800 and 5950X had no issues at all. IDK if there is such thing as PSU incompatability, but the only logical answer was power spikes, which I found about here actually

I started having problems with my 850w "80 Plus Gold" InWin PSU in less than a year. Suddenly, my PC would reboot once the GPU clock hit 2,600. I am running an overclocked RX 6800 XT. I have since replaced it with a 1300w Platinum Seasonic and the problems went away. Now I can overclock this thing to death again.

First time to hit first place in Port Royal and Fire Strike for the 6800 XT. I have a feeling it won't be long, at least for Port Royal.

I scored 11 556 in Port Royal

AMD Ryzen 9 5950X, AMD Radeon RX 6800 XT x 1, 32768 MB, 64-bit Windows 11}

I scored 49 611 in Fire Strike

I have been out of the Hall of Fame Top 10 since the 12900k owners started breaking records. Now, I need 401 points to hit the Hall of Fame Top 10 again.

Great CPU score! I saw buildzoid getting same, but he was doing it like 4825/4775mhz per CCDs. Are you using all core OC too or?
My 5950x unable to run 1900/2000FLCK and it kinda sucks

My 5800x runs 1900FLCK 24/7, but 2000 no way, at least not with the last bios, though each bios allowed me do go a bit higher, hope the next one gets me close to 2000, the Ram sticks can take it.
In Fire Strike getting the Ram as fast all possible gets higher scores incrementally with my 6800xt. At least for Fire Strike, Ram speed helped me more than Gpu OC.
