The Radeon RX 6900/6950 XT Owners Thread.

Saw this interesting video and in it, Linus mentions that both the 6900XT and the RTX3090 produced short 1000w transient spikes on the PSU.

Given the number of PSU threads we already have, I do wonder if in a year or two we'll start to see more threads about dying PSU's and people wondering if their graphics card did it.

 
I have been playing around with the MPT this morning ans have just got the result https://www.3dmark.com/3dm/58015446?

Score: 18,830
gpu score: 20,014
Cpu Score: 14,106

Now im wanting to reduce my power limit from what this is set too as temps were - 88 gpu and 109 hot spot
For some reason my gpuz doesnt show me fan usage at all is this normal?

erm scrap that, reduced the watt from 350 to 320 and set the memory frequency to 2100 from its default with no fast option yet and got -

19,019 score
20,140 gpu
14,462 cpu

Is your GPU-Z up to date? There are better apps available for monitoring such as HWINFO64.

To get a better score you'll need to ramp the fans to 100%, as the stock cooler will struggle to keep temperatures in check once you go past 300W.
 
yeah gpuz is latest version 236
Ive never given hwinfo64 much time maybe i should.
I shall try and find a balance now for day 2 day use as dont want fans up all the time but for benching its interesting.
That last score i got was basically the same as my 3090 i have just sold.

Just remembered you are using an AIB 6900 XT.

I have some saved profiles you can try if you like. Just download them and load them into GPU Tuning. They were designed using the MBA design, so might be able to reduce fan speed for AIB models.

2300Mhz/2012Mhz 1.025v Power Saving 255W
2400Mhz/2112Mhz 1.050v Balanced 275W
2500Mhz/2112Mhz 1.100v Performance 300W

These can just be imported into the AMD software, right?
 
ive re installed the drivers and still no fan speeds being reported by hwinfo or gpuz?
Have you disabled Zero RPM fan control in Radeon Software?

Perfect! Will be giving this a go later.
Nice let me know how that goes. :)

I dont have that option at all just fan tuning and then advanced control, then the max fan speed slider

I think i may have to reinstall, to see if it fixes the issue, the mpt tool shows the zero rpm as not ticked either and ive rebooted pc to make sure its set to off after re applying it weird
 
Yep, still am. The 275w balanced seems to be my go to profile at the moment.

Cheers @LtMatt
Good to hear!

I checked the Sapphire website and it does not list Zero RPM as a feature so looks like it is not supported with your model.
NITRO+ AMD Radeon RX 6900 XT 16G GDDR6 (sapphiretech.com)

Does Radeon Software list the fan RPM under load or idle?

Stupid question, the Radeon Sofware only picks up JSON files, yours are XML. How are these imported?
The AMD website is out of date for doing it manually, I don't have a 'preferences' option. I can see it under 'settings' but again, it's JSON/ZIP not XML.

Ooooohhhh...Its from the performance>tuning page, didn't see the elipsis.
 
@LtMatt those profiles are spot on mate. Balanced is the only once I've used but peak temps are lower and so far, after about 5 hours gaming, it's been perfectly stable.

Good to hear they were created on a 6900 XT MBA so should work well. Be interested to know if the other two work as well if you ever need more/less performance.
