@Grindcore77 what is your ASIC (Hwinfo non sensors, video card section)
And is this XTX or XTXH ?

 

[Grindcore77]

85.8% XTXH

 

[Veii]

85.8% XTXH

Ref LC bios is unflashable ?
Alternatively gigabyte aorus master XTXH one ?

 

[Grindcore77]

yep it's flashed with the LC BIOS

 

[Grindcore77]

I cracked 26100 with it...didn't like anything over 2880 gpu clock...2380 mem....1.35v.....

definitely a weak card compared to the xfx...

maybe mess with the other clocks a bit...without the evc my best was 25 789 I think...

 

[Veii]

yep it's flashed with the LC BIOS

Take KXTX's MPT ~ any 6950XT bios.
Change SOC max to 1150mV from 1162 down
Change Powerslider_max to 15% instead of 20%
Change CoreFreq max down to 2719Mhz
That loads as its driver approved for XTXH chipID.

Then change SOC CLK_Max to 1000mhz
And put this offset in https://www.igorslab.de/community/threads/red-bios-editor-und-morepowertool-bios-einträge-anpassen-optimieren-und-noch-stabiler-übertakten-navi-unlimited.2415/page-175#post-220265 StaticVoltageOffset. KXTX Curve to XTXH Card
From there you only need to increase the delta with an EVC and play with FCLK max , step by step.
After you found most stable FCLK while finding before highest core clock - increase SOC clock step by step.
If SOCCLK does for you nothing till 1300MHz, you lack FCLK & MCLK for it to make sense. Soo pull it down again

* Don't use TempDep VMIN, but do the offsets via EVC.
So you start with a "better" curve foundation. Also don't force FMAX toggle , let clock be dynamic.

 

[Grindcore77]

Ahhh okay! So I can just download a kxtx into mpt but leave the LC bios on the card as is..I don't have to reflash?
This is all new to me 😆

WWilgivwe it a try and see how it goes! Thank you!
yes I wasn't using temp vmin setting...was just using the evc now.

Yes yes
Grab any random KXTX bios from techpowerup
take its Powerplaytable (MPT select your gpu, then load file, pick the rom)

Then change the written 4-5 options, soo drivers dont turn to 500MHz failsafe mode.
Afterwards put SOC clock lower too 1000MHz , its plenty at first.
Use my gifted research to turn this 6950XT curve, 6900XT compatible.
And with having a more granular voltage curve, now slowly extend (telemetry fake) the values with EVC ~ without supplying a fixed voltage. Just an offset.

Curve will still apply, if you manually OC
Sadly you can not change frequency scale via I²c , but technically you can change AVFS override (c) , by the same amount you as you add in EVC (-0.050000 = 50mV drop in height=voltage drop)

Last part is advanced method, and unless you find a way to "apply EVC on boot" , this will cause you trouble.
StaticVoltageOverride is the input voltage. Do not touch it outside of the given A,B,C formula. Its card and SKU specific.
What users can change is AVFS override ~ but you might as well not either

This is all new to me 😆

Dont worry, it's for everyone new~

 

[Grindcore77]

Hmmm ok...so change the initial values first so that the card doesn't go into fail-safe mode...
Then work on fclk first...have you found anything more about the min fclk/boost settings? No need to change?
Then work on the soc frequency?
Then gpu core?...where does memory OC come into this? Just leave as is? EG..how we have been doing previously?
Now with the evc...I change offsets in increments while searching for higher clocks..do just soc first with evc...fclk then soc?
When I change offset with evc I must also change c setting in mpt? The static offset?

Oh and amazing work by the way! Rdna2 master 😃

Beitrag automatisch zusammengeführt: 13.06.2023

Or sorry.. just leave gpu core as dynamic? So don't mess with its settings at all?

 

[Veii]

@Grindcore77 maybe reread #27.576 again
Prepare KXTX profile for the driver ~ reload driver to verify you did everything right

Then push its curve down to fit your SKU [StaticVoltageOffset] ~ reload again
Then lower SOCCLK , to not uselessly SOC-Plane (rail) package-throttle, when going for MCLK & FCLK OC & OC how you've OC'n so far
Push FCLK as high as you see perf results (too high pushes voltage high = reaches faster throttle point).
Push MCLK higher. Solidify and leave SOC alone. Move to core and offset voltage through EVC.
After Core clock caps, lower it slightly and push SOC clock. See if you see any difference with 1100-1200 . If not, stay on 1000Mhz and work further on MCLK & FCLK
(as SOCCLK is not the limiter yet)

Or sorry.. just leave gpu core as dynamic? So don't mess with its settings at all?

Just change Freq Max values, not min and leave it be dynamic.
MPT has options to enforce fixed clock, Dont do that

 

[Grindcore77]

Ok! I'm sure will be much easier when sitting in front of the pc!

Thank you again

Ok I understand now the evc will only be used for gpu core as normal....you don't mess with soc voltage with evc?

Beitrag automatisch zusammengeführt: 14.06.2023

So static offset you set at start to make work with the card in mpt...then leave that alone...evc/gpu core/soc as needed when ocing core

 

[Grindcore77]

I'm still using mct with this? Changing gpu/mem ect

 

[Grindcore77]

Ok..I don't know what I'm doing wrong...but I changed everything in mpt as instructed...cant even get it to complete a run in timespy...crashes everytime 😐

 

[Veii]

Ok..I don't know what I'm doing wrong...but I changed everything in mpt as instructed...cant even get it to complete a run in timespy...crashes everytime 😐

Could you track voltage in any other load like unigine heaven or somehow get it from timespy
Where do you crash ?

I point to SOC because that is not factored in ASIC %
ASIC score itself is compatible for that curve.
Maybe SOC one is too droopy. Really depends what VID it requests for you

If its something stupid like 1v for 2719MHz "stock", no OC mode
Then you have to push AVFS override (sectioned C) higher
Really depends where it crashes. Need more data

 

[Grindcore77]

Hmmm ok.....will have to investigate further tomorrow.....it crashes throughout gt1 sometimes I get flickering which would be mem related?
Is it possible that the fclk stock frequency has something to do with it? I'm pretty sure the stock LC bios is lower than the 6950 one? Maybe not enough volts for soc? I lowered the fclk to like 1800 from 2020? Can't remember exactly what the stock number was...and it seemed to get further in the run..but that could have been a coincidence..im Not sure

I don't think it's gpu because when I load in to mct I think the max it shows is 500 min 2304 max? Or somewhere around there...

Also 2917 is already entered in mpt I didn't have to change it...
The overdrive limit at 5000 doesn't have anything to do with it either?
Well until I'm able to try and run again it's just guesswork...I can try and run heaven and see what info I get from that

 

[Veii]

Yes ?
You should see MCT defaulting near 2650-2719 ~ more than 2700 without user intervention

Like here ~ its still an XTXH, dont mind

Those are changes you want to do ~ on a KXTX MTP -> XTXH Chip (73AF ID)

And then you sadly have to figure out if SOC is fine or behaves awkward. Because that is not factored in with ASIC %
Its either:

Or

One of both

Its better via Guardbands instead directly capping it lower like it was for the LC REF.
But ultimately it is card unique if SOC stays compatible or not.
No need to change more. At worst adapt memory voltage.
But yes, MoreClockTool has to report optimally full FMAX (that is 2719MHz out of 2719MHz)
If curve is not fully perfect, it will report 2600 or 2550MHz as "default max".

Your work is here to only port KXTX curve over, because its more granular and honestly a better foundation.
Its still overvolted - because AMD & ASIC (binning) Compatibility ~ but nevertheless its much better than the stock XTX or XTXH ones
6x50 series cards generally are much better tuned.

Oh it can be also something stupid like

Memory "underclock" , causing trouble on LC bios
It shouldnt, but LC bios has a slightly moved 2300MHz Memstrap vs XTXH or KXTX.

---

Hilft das ?

 

[Grindcore77]

Ok will see how I go with that information...
When I load mct I'm definitely getting that lower max clock of 2304mhz

 

[Grindcore77]

When I'm doing those initial mpt settings can I do my usual power changes? Or just leave them stock?

 

[Grindcore77]

Ok...using the second option above my clock is 2334higher than before but still too low

Beitrag automatisch zusammengeführt: 15.06.2023

Hmm my power limiting mpt is only showing 284?

Ok...I have 2639 showing now as max in mpt...but still not high enough

Beitrag automatisch zusammengeführt: 15.06.2023

Ok....I tried both options you gave and it went a bit higher...max clock in mct..it is now 2644

 

[Grindcore77]

Ok...good news I guess It runs timepsy no dramas at stock 😆😆

Beitrag automatisch zusammengeführt: 15.06.2023

Ok ok! I have it now..mct showing 2719!!

Beitrag automatisch zusammengeführt: 15.06.2023

Ok..so working with fclk I should use evc for the soc offset when doing this or just see how I can go with fclk clock?

Another thing...am I cranking up my power limits in mpt before trying my clocks?

P.s....upto 2200 fclk with no evc offset...2230...black screen!

 

[Grindcore77]

Quite weird...after reboot I wanted to mess around again..mct now displays 2677 for gpu clock?

 

[Veii]

No need, SOC voltage provided is actually plenty

Another thing...am I cranking up my power limits in mpt before trying my clocks?

Sure, why not.

mm mm
Its strange that you hit 1.2vmax that early
But I guess

You should track what SOC voltage worked for you and soc preset.

 

[Grindcore77]

Cheers for that....will tinker around with it and see what happens.
Is the driver important? At the moment I'm using the latest..
having some optimal weather lately..ive had the chiller to 5c the last few days!
Thanks again for all this info....hopefully I come back with some meaningful results!!

 

[Veii]

Is the driver important? At the moment I'm using the latest..

Yes, they changed recently a lot
It broke my tuning 3-4 months ago.
Then i lost access to the card, and ya - i dont want to release something semi-stable , even if its very good
Tho the research stays for the community to continue now. I'll help where i can.

It feels like the card takes now even more voltage with the new drivers, for no reason
But the new drivers are faster, soo its ok.

SKU Asic conversion offset remains unchanged, its 1:1 , well nearly perfect.
I wish i had it for XT and XTX SKU ~ but you need two identical cards with identical ASIC % ~ to run a custom curve @ near same temp, in order to get just the delta out with the math.

That the stock KXTX curve is still overvolted for you - oh well, unfortunately
For better tuning, i would need active data from you

Try how low you can go with the voltage slider, to stabilize 2719MHz set.
If you can't reach it by stock training methods (every boot the card retrains, and every driver restart),
set it as OC mode & let me know what core VID you run (GPU-Z) under Timespy
(beware hitting any power limiter, will lower VID)
+
optimally pausing [space] the unigine heaven benchmark on the entry sittingbench location
(1080p maxed out, x8 tess, windowed)

HWInfo you only use for the SOC "set" voltage
But those voltages are semi unreliable
What interests you is VID. That you get either from wattman or just keep GPU-Z open

@ShirKhan

Ich habe heute nochmal die 24.750 geknackt allerdings bin ich so langsam aber auch an dem Punkt an dem ich bei den derzeitigen Temperaturen nicht weiter komme da ich bereits 2.850 MHz Anliegen habe.

Ich hatte ja schonmal wegen der Treiber Geschichte gefragt, mich aber bis jetzt noch nicht im Detail damit beschäftigt. Wenn ich allerdings die top Scores ansehe Stelle ich fest das einige teils mit deutlich geringeren takt UND dem normalen 16 GB vram teils deutlich höhere timespy zählen erreichen als ich .

Zb eine RX 6900 Referenz die 24000 schafft bei gerade Mal 2610 MHz takt . Wie kann das sein ?

Könntest du mir da vielleicht ein paar Details geben mit den Radeon Treibern .. sind da wirklich so deutliche Sprünge drin wenn ich den passenden älteren Treiber nutze?

 

[ShirKhan]

Was für Details? Hier habe ich deine kürzliche Frage dazu beantwortet.

sind da wirklich so deutliche Sprünge drin wenn ich den passenden älteren Treiber nutze?

Das findest du raus, wenn du es willst. Ist jetzt auch keine Lebensentscheidung, einen Treiber mit DDU runterzuwerfen und einen anderen draufzumachen.
