[Little J]

Thank you. My 6900 XT is running into black screens when trying to do anything you've showed above.


Any improvement at all?

With HDMI cable I also had black screen when using DPM 3 Memory VDDCI 900mV and MVDD 1400mV. Try with DP cable. If that doesn't help I don't know what the problem is.
Anyone else having a black screen?

Not much improvement. Superposition bench stock 6944 points. Memory OC 2262Mhz fast timing 7022 points. Maybe I should rewrite something else in MPT but I don't understand what curve settings should be set there at all.

 

[ShirKhan]

Mal die Timings runter gesetzt?

Ja, sowohl im MCT als auch im MPT.

Weder kann ich den Min-Takt im Frequency-Tab des MPT höher einstellen als den Max-Takt im MCT, noch kann ich den Mem-Takt im MCT höher setzen als 2150, auch nicht nach Erhöhungen bei den OC Limits. Nach einer dieser beiden Änderungen gibt's Freeze oder BS. Verschiedene Varianten versucht, auch unterhalb 1156/2312.

Does it work on your card without raising mem voltages? I am not a big fan of memory overvolting.

 

[Little J]

Igen, mind az MCT-ben, mind az MPT-ben.

Nem tudom az MPT frekvencia fülén lévő min órát magasabbra állítani, mint az MCT maximális óráját, és az MCT-ben lévő mémórát sem állíthatom 2150-nél magasabbra, még az OC-határértékek növelése után sem. A két változás egyike után ott van a Freeze vagy a BS. Különböző változatok próbálkoztak, szintén 1156/2312 alatt.


DP-kapcsolatot használok.

Működik a kártyáján anélkül, hogy emelné a mem feszültséget? Nem vagyok nagy rajongója a memória túlfeszültségének.

Still testing. Just restarted the PC 2280Mhz fast timing.
Now default timing memory 2312Mhz and now good.

750mV DPM 0 1250mV
900mV DPM 1 1380mV
900mV DPM 2 1380mV
900mV DPM 3 1380mV

SOC default 1150mV

I do not use MTC.

MCT is like Wattman.

How do you manage to put min above max clock in WM? That shouldn't be possible. And it isn't here.

I do not set anything else in the wattman except the memory clock.
Everything else I write into the MPT.
I simply write the values into MPT and write SPPT.

Hmm... that feels low. With my 6750 XT i got 7905 max.
Granted with unstable (for daily) setup of 2925 (2875) mHz clock and 2312 mHz memory with FT2 (cannot run FT2 without artifacts for daily) .
So i would've expected you to see 7500-7600 as result.




Will try to override my memory clock limit, just for interest

UPD. System locks down after blackscreening to 0.1 FPS (well, it returns image at least, I guess), making it basically impossible to use because everything is stuck. Even if i go with +2 mHz to VRAM on top of default timings.

Mit diesen Einstellungen



kommt also das zustande.



Bei mir nicht, auch nicht nach Anpassung an die geringere Max-GFX-Default-Frequenz der 6900 von 2660 MHz. Und der 100 MHz-Abstand muss auch in den Frequency-Einstellungen eingehalten werden. Sonst freezed die Karre so heftig, dass im Safe Mode die MPT-Settings gelöscht werden müssen.

An der Unmöglichkeit, den Memory-Takt über 2150 zu heben, ändert das GFX-Gewürge leider überhaupt nichts. Blackscreen nach Übernahme, im Anschluss an die Anhebung des Werts in den OC Limits auf irgendwas zwischen 1075 und 1156.



Eine Idee, anybody?

There is a small problem.
You cannot go above the factory maximum GPU clock speed.
2622Mhz.
If I set it above that, I immediately get a black screen.
What is the solution? Does it detect the factory maximum as the minimum?

 

[Little J]

For the minimum, enter the factory max boost clock. If you set it above that black screen.
The max boost is detected as the minimum and set to it. I don't know how to raise it above that.
Anyone?

Tried like that, still black screens if i set any amount of mHz higher than default maximum (2312).
Default reported is 2623 (default used - higher, around 2678-2685).
Set 2623 min - set min in Wattman = 2681.
Set 2600 - set min in Wattman = 2621 (or 2623...).

2621 and 2623 are not good. Black screen. Only 2622 is good. Which is the factory default. So maximum 2580-2590 boost.

I have different card and my default is 2623


See?

See?

For me the default is 2622. In fact there is no maximum clock speed only minimum. Since the card tries to enter safe mode (500mhz) but the new safe mode is the specified 2622Mhz. I don't understand why if I set it higher it doesn't like it Maybe it always reads back from the bios chip? Or maybe I should turn something off or on in feature control? Unfortunately I don't know what those things in feature control mean. I'm still trying.

To tripple check this is not a 6750 push-patched anomaly
If you touch nothing else, no VMAX no Powertarget , only VDDIO & VDDM + Wattman limits higher (overdrive mem FMAX)

Will you trigger failsafe mode @Little J
GFX change (FMAX), voltage change VMAX, powerbudget change - all trigger a failsafe mode (crosscompared with internal state)
But the overdrive limiter do not. Except when you go above a certain value you still trigger failsafe mode.

Soo question,

Change on those two sections only - no FT2 or anything
~ Will you trigger failsafe without pushing mem higher (just with higher wattman limits) ?
~ And will you trigger failsafe by exceeding 2150 ?
Cards should have mem straps till 2250 strap (last one on non 6x50 cards)

Thinking more about it, one could just flash 6750/6950 mem timings
Then unlock card again , and reflash with --exclude-memory-training , the old bios with functional SPPT
In order to make it out of boot-init state and memory section working

---

Normally the issue limiting us back is , getting patches from EEPROM to push into SME on onboot init past flash-state
As its a whitelist method - downgrades work
Once patch is pushed in, limiter is changed.
Soo if you card missbehaves , you somehow did it.

Else you maybe have found a bug/exploit past failsafe mode, which both need closer inspection
If we could focus change values, it would be long times done. But currently we have to find a vendors oopsy soo the patches push through
Its quite simple, yet far away - as it doesnt boot up unsigned

Above 2150 the failsafe is triggered. I was thinking of pointing to the 6750 bios (which obviously has better timings) and doing the same thing, rewriting the minimum clock.
I will try what you wrote. If I understood correctly.

Unfortunately I don't quite understand. I am writing from translation

On init to what i figured there are 3 states:
~ GOP check & expected-devID check
~ SPPT check (which we fail but it still passes through, yet prevents DevID rebrand)
~ memory and AVFS calibration ^ to above
~ EEPROM "expected" lock state, if EEPROM lock matches expected state by flashprogramm
// (3.20 & 4.69 expects unlocked state, 3.31 & 4.71 expects locked state)
3 crucial, and one connected

If you dont please all of that, the patch won't push through (oh they also are checked by age and "version upgrades")
// which is why LC bios passes through - Vendor AMD did an oopsy with XTXH-LC SKU without artificially limiting VMAX to break SPPT compatibility
Soo to potentially get a full rebrand done, you need to focus edit values and inject a functional SPPT - soo onboot init check passes and then card rebrands and reboots 2-3 times before init

This works with downgrades (because lower SPPT targets are always met), but as seen is a struggle with upgrades as SPPT failes & upgrade is prevented
What does work on all of the cards now, is to run a bios with better memory timings (FT2), better V/F curve & have to manually load back old SPPT values, to stay out of failsafe mode.

That's all so far.
At least onboot check is broken and flash exploit works..
Type-C overcurrent "trouble" is also bypassed
Yet still not satisfactory. If upgrades work, shader unlock works by itself ~ its no wonder why it's such a trouble

Sorry - what!?

Hat das jetzt noch irgendwas zu tun mit dem Versuch, Little J's Ergebnis mittels MPT und WM zu reproduzieren? I am completely lost.
