RDNA2 RX6000 Series Owners Thread, Tests, Mods, BIOS & Tweaks !

If you set higher values via MPT and they are ignored in-game then only flashing different bios (XT) would help.
And there is no flashing tool available yet for Navi2x cards.

 

I have also submitted a bug report to AMD about this.
I have this same problem since a week now after I bought the new monitor (ROG Strix XG27WQ).
The monitor supports 165Hz.
As soon as I set the 165Hz refresh rate, the VRAM clock stays high at idle desktop.
If I switch the refresh rate to 144Hz then the VRAM clock drops.

On the other note, I have been running my 6800XT now at 1015mV@2600MHz and 15% powerlimit which gives TimeSpy score of 19043.
Played Borderlands for many hours at Ultra settings, with Average FPS 146 in DX12 mode with average in game frequency of 2545MHz.
Need to analyze the data from Assassin's Creed Valhalla for average FPS and Frequency. In 3 hours game play yesterday FPS was in range of 100.

 

Any other weird quirks like the one regarding mouse click not working for few seconds after monitor wakeup I mentioned in my earlier post that you might have come across? I can test all these on my 2080ti for A-B testing before it is sold.

 

Regarding performance my card is just 9 % faster than yours with max OC/UV and MPT. I could go a little bit higher with TGP and clocks but I start getting into diminishing returns territory. You should try MPT as well. What is your processor? It might be helping with your score as well. Mine is an old 8700 non-k @ 4.4 Ghz.

 

When you set 1025v from radeon software is that what you see at gpu-z? It's never same for me so i punch max vcore limit via MTP.

 

This is an important discovery. Just checked, I am always witnessing max core voltage for chip on GPU-Z, no matter what I set in Radeon software.

 

Yeah that's why you are stable. It's actually 1.15v. When you limit your gpu will be drains less power and will be much cooler.

My daily is here: https://i.hizliresim.com/N0MUyW.jpg

This keeps 2600mhz in game.

 

What is you voltage ? The link is starred out. For me it's max 1175 mhz even in Radeon software though lowering too much results in a crash so maybe we are just getting incorrect info and voltages are being applied.

 

I hope it work now.

 

It's visible now. You have changed quite a few setting for voltages. Would like to know what other people are experiencing. Cause like I said, I think voltages are being applied as lowering them too much causes crashes.

 

Frequency limit: to be sure never goes above that which might cause crash. Also slider-50mhz will be boost frequency. 2660-50=2600mhz That's the boost formula of AMD

Voltage limit: obvious reasons.

Soc v limit: No need to push more don't effect performance. max 975mv also works.

Power gpu limit: To be sure enough power avaible. 4k needs more power than usual which leeds low freq.

Tdc limit: Same as above.

 

Your SOC V is more than mine on default, might want to check that. Also, be careful with power limit in MPT as that is just GPU chip power draw, you need to add around 40 watt more for other board components. And if you using additional 15% power limit than consumption can go over 420+ watts. At least that is my understanding of it. Hope you have good PSU.

 

Yes you are right but with 1037v gpu power will be around max 240w. So, no need to worry about it. I can push more than 375w (150+150+75) anyway psu&card can handle it.

I mean max soc voltage. 6900xt has lower soc voltage by default but it will drain 1150v on gaming. Just lower the max value thats all.

As you see 4k valhalla drains around only 220w.

 

Finally got my hands on a 6800xt. Seems to be a decent card:

Time Spy - 20,241 Graphics Score

Time Spy Extreme - 9,729 Graphics Score

Port Royal - 10,298 Graphics Score
https://www.3dmark.com/pr/704880

 

Just did a little more ticketing on my 6900xt but it seems that your card is a beast. Comparisons below. Though I think my processor is holding my card down at least in Time Spy.

Port Royal

Port royal is the best showing for my card at ~6.5 higher than yours.

 

you have one of the best time spy graphics scores for 6900xt. your cpu is fine.

 

Hmm, I don't know as Port Royal and TPE are giving higher scores but yeah it's not big a game changer. So have you stress tested you GPU with with any of the 3d mark stress tests?

 

No never tried. Only run some 3dmark bencmark o get better score with full oc that's all.

 

I have not pushed mine to the limits yet with MPT.
With the 15% power limit, this is maximum what I can achieve.
In game power consumption increase over default setting is about 35W-40W.

I have Ryzen 5800x processor and SAM is enabled.

I will try MPT. I did not get the time to play around that until now.

I have replaced the original cooler on 6800XT with EKWB water block.
Maximum Hot Spot temperature for me is now 60°C and GPU temperature no higher than 44°C.
I do hear now coil whine which was hidden before by the original Fan noise.

 

I have set the Radeon Software to 1015mV at 2600MHz.
Yes this is not the voltage that the GPU uses.
The actually voltage varies and I have seen with HWiNFO voltage goes up to 1100mV maximum.
Most of the time it is goes to 1093mV for a frequency in range of 2560MHz-2575MHz.

What I also noticed actually is that on my GPU the performance is worst if I set voltage higher than 1015mV at same frequency of 2600MHz.
The Time Spy score drops if for example I set 1020mV@2600MHz.

I also tried to go higher in Frequency than 2600MHz but that does not give any better result for the power limit of 15%.
I think my GPU is cable to achieve higher performance as soon as I throw some more power onto it with MPT.

As mentioned before, I did not get time to play with MPT until now.
Too busy playing three games in the Holidays: Assassin's Creed Valhalla, Cyberpunk 2077 and Borderland 3.
