Hey sei lieb zu mir😉😁 Euch noch einen schönen Abend ✌️

Thanks @GerryB my Soc undervolt is finally stable; I didn't even think of increasing the minimum voltage. I'm pretty sure that's what I was missing. The Vram is still a mystery to me since I was able to do 2150 FT2 with no problem at 675mv/1250mv; now I'm forced to do 2140 FT1 (but when setting DPM3 = 1070, you move up a timing strap, so technically it's at 2140 Standard Timings) or 2150 FT1 at 900mv/1350mv with no DPM setting. I'm worried my Vram may be degrading, so I'll just see if I can get an RMA.

Do you think I could be able to hit a 23k graphics score, or am I completely temperature- or power-limited? I tried to increase my core voltage by 25mv and Fmax by 65Mhz, but it only resulted in a 150-point increase.

Nee,
ganz ohne Quatsch, der download geht bei EA ganz gut vonstatten.
Bei mir schon auf der Platte!

could be, ... other ones with 25mV more@h2o should reach more maxClock, but also with mooore Watt

think different
what´s about 281W with PL= -10%, ... would be 281x0,9=253W not a better 24/7@air?
If it is enough für 21 ... 21,5k score it sounds better to me.
(if not stable, try a little bit less GFX-clock, 2565-->2500MHz)

try a little bit more vram-UV

additional you can proof, if a little bit more SOC volt helps with fclk 1991MHz (and fclkboost 1991)
I would try SOC 1006mV.
This is a good exchange, more Fclk with your "low" VramClockFT1

You have a great Chip, with a nice Offset MPT-Volt to MCT-Volt, enjoy.

The Vram is still a mystery to me since I was able to do 2150 FT2 with no problem at 675mv/1250mv; now I'm forced to do 2140 FT1 (but when setting DPM3 = 1070, you move up a timing strap, so technically it's at 2140 Standard Timings) or 2150 FT1 at 900mv/1350mv with no DPM setting.

sorry, but FT2 is not a granted value, ... only gurdi with a Strix 6800xt-LC can do this, but also only with help setting DPM3=1075

time strap
what happens, if you try MCT vram 2142...2144...2146, yes I know, it´s eff.<2140
myself with 6800nonXT use DPM3=1029 vram 2066 without problems, gives a good UVing
or
what happens at the other timing step
DPM3=1062 with vram 2124, is it stable ?, when yes, try vram 2130

How are the vram-temps?
above 50°C there is no way to easy experiments

 

[Evgasüchtiger]

Kurze Frage bezüglich TDC Limit .... es bringt ja bestimmt Stabilität wenn man die Ampere Werte im MPT erhöht oder?

 

[MehlstaubtheCat]

Die Standard mäßig aktiviert sind, werden niemals erreicht, also bringt es auch nichts!
Warum soll es Stabilität bringen, da gibt es keine "Verbindung"!

 

[Evgasüchtiger]

[GerryB]

@Evgasüchtiger
Schau halt mal in HWinfo, da fehlt Dir NIX! ... max.Auslastung= 65% bei GFX und 40% beim SOC, ... passt.

Das war irgendeine von Deinen nicht belabelten logs, ... uii, was auch immer das war.
das TDC-Limit wird ebenfalls mit dem PL-Slider erhöht/reduziert, ... da könnte es höchstens passieren, wenn
man SOC-TDC <20A setzt und PL= -10% nutzt, das es mal knapp wird

btw.
AFMF works in Jedi: Survivor

could be, ... other ones with 25mV more@h2o should reach more maxClock, but also with more Watt

With 1075mv on the core, I am able to do 2625Mhz and at 1093/1100mv I was able to achieve the 2660Mhz Fmax of the XTX chip. Although I think it peaks around 300+ Watts, sometimes I am trying to stick to the default watt limit allotted by the Gaming X Trio. It just feels bad to me to lower the wattage to 250 and, in turn, lower the clock speed because it feels like I'm not utilizing the maximum performance of the card. I always wished to have it at a flat 2600Mhz effective but my cooler can't handle the wattage it requires. At 1050mv I am able to have a flat 2500Mhz. The Soc undervolt didn't reduce as much power as I hoped. I was going to bump up the core to 1062mv to set the Fmax at 2600Mhz and achieve 2550Mhz effective, but it barely exceeds the 281 watt limit.

try a little bit more vram-UV

Unfortunately, these settings aren't stable on my card, but I am content with the previously stable settings. I just wish I could have at least 50Mhz to 100Mhz on the core with the current power limit. I don't think there's any other undervolting I can do to allow the core more power for the clock speed increase. A 22,300 score isn't bad, though.

I just see scores like that, and I wonder why my card can't achieve that.

 

[DaHell63]

Nach den Ergebnissen von @Shir Khan kann sich der sogenannte Normalo nich richten

look at the temps, ... therefor you should really optimize your graphiccard in a wattrange with good temps
look at users with only small h2o-radiator, like bread, see attachement (is a 6950)
hotspot<60°C works good in his 200W run

only for benching try with open case and 100%RPM to achieve a good temp
and probably set the target temp higher, ... 80°C -->95°C, may be, then later throttle

and please check your FeatureControl

Scaling active means, that with higher DPM more Volt are used, ... but deactive means, you get
low Volts between DPM0 and 1, = instabil!

At 1050mv I am able to have a flat 2500Mhz.

a flat GFX clock in TS GT1+2 is not good, it´s better to use boost, the lower the watt at timeindex xyz the more boost
if you play with a powerlimit
You should really look at Scores with Powerlimit and not Highscores with open Powerlimit!
(only open powerlimit is with a flat clock)

flat clock is a dumb old idea, the last hardware with that was polaris
newer hardware can boooooooost

with powerlimit >>300W its better to have Kryosheet
look at the delta gpu temp to hotspot

btw.
If you really RMA your cheap 6900, then look at the GRE, this ist the best value@23k score with low watt.
https://www.3dmark.com/spy/47745101
don´t forget, your 2660MHz 340Wtgp means 400Wtbp, but the GRE needs only 260...280W?
260Wtbp is easier to handle@24/7.

additionell
for me, I have to look, to set the min clock not higher then the min real clock in GT2
if the min clock is to high then clockstrechings works not so effectively, ... the arbitrator is surprised
and
whats the best idea?
try to achieve a score 7% below default and with 50% better efficiency
6800@203W = 16253points = default in PCGH-Review (16253/203=80)
6800@125W = 15126points = optimized with good temp (15126/125=120)

What means 7% lower then 61fps@4k = chill 57fps at my 60Hz freesync monitor, thats enough.
with faster monitor then AFMF is usefull

By flat, I meant that due to the undervolt, I wouldn't achieve 2565Mhz exactly the maximum boost I would get with the droop would be 2500Mhz.

hotspot<60°C works good in his 200W run

You have an MSI Gaming Trio as well; did you switch to Kryosheet/Liquid Metal on the stock cooler or are you running water-cooled? The stock cooler is so bad; I doubt the heatpipes are making good contact with the die; the hotspot delta between the core is slightly over a 35-degree difference.

I was actually hoping for RMA to, in turn, receive a 7900 XT from MSI since they discontinued production of Radeon products a while ago and are most likely out of stock of RDNA 2

 

[GerryB]

my low temps are with low watts
no need for Kryosheet
may be, the delta GPU-Edge to Hotspot growths x² with the Watts

one thing would be interesting:
my 6800nonXT is with 3x92 mm Fans
Are there really 100mm Fans at the 6900?

No, MSI Gaming Trio coolers are all the same, from the RX 6800 all the way up to the 7900 XTX.

 

[GerryB]

sounds not good in mooore watt settings
the 6950trio have in this way to high temps and is too loud

 

[GerryB]

Heute hatte ich mal Zeit, um den schlechten PR-Score von PCGH ziemlich genau zu matchen: ... only Vram matters
(PCGH@stock=203W vs. optimized=121W)

 

[Verak Drezzt]

@GerryB und das bei 121W^^ was hat sie Stock, 220W ?

 

[GerryB]

203 die Ref und die Trio 215

DaHell`s StrixOC wohl gar 227
aber auch 3x100er Lü.
(den AufpreisOC wert)

sein PCB/VRM ist auch supi, da kann er Spässchen@open PL machen mit PR-Score 10k

btw.
PR ist ein absoluter Sonderfall, weil er extrem gut auf Vram-OCen skaliert.(ab Werk stock Fps verschenkt)
z.Vgl.
Im TSE zählt dann doch eher die Shaderperformance, ... da ist mein derzeitiges 24/7 ca. 5% langsamer als stock
aber auch noch 70W sparsamer.(wäre in Games dann wieder 57fps statt 60fps = passt)
Am Meisten wunder ich mich über die 7700xt, die ist im TSE gar net so weit weg, trotz der vielen Watt+5nm.

 

[Evgasüchtiger]

Ich habe gerade mal nochmal um 25mv uved. Das fand der Timespy aber nicht so schön. Mit 50mhz lief der TS dann immer durch. Im TS 1 lagen dann ca ~2185mhz und im TS2 ca ~2175im Durchschnitt an . TS sagt 20500 Grafikpunkte. Hatte leider nicht mit geloggt wieviel Spannung real anlag. Mit 2300mhz (- 2235mhz) waren 20900p.

Also Wollte eigentlich bei über 2200mhz bleiben. 2100 TS Grafikpunkte mit diesem Setting möchte ich gerne erreichen. Aber wo soll ich noch optimieren?! 😁

 

[GerryB]

Dann machs halt schrittweise!
25mV sind gigantisch viel Holz in der Curve, ... man geht eher mal von MPT 925mV auf 918 ... 912mV, ... dann
klappts auch besser mit mehr maxTakt in GT2, ohne das man am Satelliten crashed.
(bei sowenig Takt reicht auch 200W im MPT, ... zum Spielen kannste ja immer noch PL+15 zuschalten)

btw.
Hohe Scores/avg.Watt gibts eeh nur im PL, ... die GPU durch Takt oder Volt ausbremsen nimmt den Boost weg.
sieht man ganz deutlich, wenn ich mal auf PL= -8% gehe, dann geht Takt+Volt schön hoch und runter, um das letzte Fps rauszuholen, ... wie in realen Games, wo man zusätzlich statt PL auch noch Fps-Limit nutzt.
(die log-files brauchst Du nicht extra posten, meist sagt einfaches Bild von HWinfo zusammen mit dem Taktverlauf schon Einiges über den TS-Run)
