No, i did just a repaste for the chip few months ago and didnt touch the vram .Nothing special like extra fan.

 

[GerryB]

ohne MPT war FT2 im Adrenalin-Treiberpaneel verfügbar ?
normalerweise muss man das erst im MPT freischalten

2124ft2 wäre natürlich extrem gut, besonders wenns eff.2124MHz sein sollen
da würde man aber bestimmt auch DPM3= 1062MHz setzen müssen
bzw.
2124-12= 2112MHz eff. und DPM3 so ca. 1058MHz

muss ich mal bei Gelegenheit probieren, ob mein schlechter Vram so scharfe Timings schaffen kann
mit den stock-Volts oder weniger, ... werde mal 6/12mV mehr probieren als bei DPM3=1070
also
im harmlosen Kombustor gehts erstmal mit moderaten Volt
aber
im PR brauchts dann schon deutlich mehr Volt auf dem Vram, ohne das ganz genau auszumiezeln

712/1300 wäre dann schon nicht mehr sparsam, wenn auch immer noch weniger als default 850/1350
2124ft2 war nicht 100%ig stabil aber 2122ft2 = 2110eff. reicht ja auch (siehe Anhang3)

2132ft2 mit 725/1312mV bringt bei selbem PL dann Nichts mehr, weil der Vram vermutlich zuviel Watt
verbraucht und/oder die Fehlerkorr. dann schon bremst bei mir (siehe Anhang4)
DPM3 = 1062 für diesen letzten Test

 

[GerryB]

Was ich nicht ausschliessen kann, ... evtl. braucht der AFMF2-treiber bei mir ein mue mehr Volt beim Vram.(700/1262)
(will ja nicht hoffen, das mein Vram inzwischen degeneriert hat)

Fazit:
für meinen Vram bleibt 2142ft2 die günstigste Variante für FT2, ... = 2130MHz eff. + moderates Timing
bringt im PR den effizientesten Run

edit:
VDDCI = 693mV reicht auch noch, scheint also nur bei MVDD etwas mehr zu brauchen mit dem Treiber

 

[Tornavida]

Hab eine meine Einstellungen hier gefunden und die funzen nach wie vor ,happy I am

@GerryB

Hast natürlich Recht, FT2 nur via MPT

damit jemand nicht verzweifelt

@cra3khead

i told u bs yesterday, i did mean Fast Timings only via Adrenalin not FT2 which is via MPT i didnt use yesterday,sorry

 

[GerryB]

Das war gar net schlimm mit dem Verwechseln von FT1 und FT2, ... dadurch hab ich halt mal wieder etwas rumprobiert.
Und man lernt seine Hardware besser kennen, ... auch nach so langer Zeit gibts immer mal was Neues, was man so noch nicht im Focus hatte.(weils beim Launch noch nicht ging)

Bei Dir müsste mit den hohen Vram-Volt@stock eigentlich auch noch 2132FT1 stabil sein.
(ist dann eff. 2120MHz)

 

[Tornavida]

Ach das passt soweit, hab die alten Werte nun via MPT geladen und gut ist. Temps besser und Leistung wie bei stock mit Optimierung bei etwas UV. Kein Bock dran weiter zu fummeln zumal jetzt via MPT wieder 1250 anliegen bei immer noch FT1 2124 und keine 1350. No Need 4 records oder 0,5 FPS mehr.

 

[cra3khead]

What I can't rule out is that the AFMF2 driver may need a few more volts for the VRAM. (700/1262)
(I hope that my VRAM has not degenerated in the meantime)

AFMF 2 is harder on the VRAM even on RDNA 3, but I can't deem it a timing change as they did with 23.7.1. My vram has definitely degraded, although I was running too high of a voltage when I first got my card due to ignorance.

 

[GerryB]

may be the 7900erAir-Vram is also too hot
therefore some User had more problems with there OCing with the sharp AFM2-driver

 

[cra3khead]

@GerryB I think my vram has degraded too far. What settings could I use to lessen the amount of crashes I'm getting? I think I need to RMA at this point. I just hope it's not a whole other headache.

 

[GerryB]

Yes,
use the standard DPM3=1000MHz and try 2140FT1 with your Volts.
second
try and error, what voltage is required with 2150FT1

 

[cra3khead]

try and error, what voltage is required with 2150FT1

I don't think my card can do 2150 anymore, not even with the default voltages.

Update: Your new settings helped a little bit, but I'm still seeing texture glitches. I think it has to do with heat; when the card goes over 60 degrees on the core, I see way more. I turned on FSR 3 Quality to lower the heat to around 52 degrees, and now I can play full matches without a crash in the BO6 beta. I don't know if there's anything else I can do to fix it. RMA would probably take about a month, and my only spare GPU is an HD 7870

 

[GerryB]

I don't think my card can do 2150 anymore, not even with the default voltages.

why?
I would think, if 2140ft1 works with 700-1262 then 2150ft1 could work with 706-1275.
(if the vramtemps are not to high)
If not, I would try 6mV more SOC, may be it´s not the Vram but a SOC issue.

btw.
may be, ... the default volts 850-1350 are too high = too hot

 

[cra3khead]

If not, I would try 6mV more SOC, may be it´s not the Vram but a SOC issue.

How could the SOC affect glitching textures? I know it's a vram issue because when Windows Night Light turns on, as its fading to orange while I have FT2 on, the screen will show a bunch of colored pixels as you would see with dying vram. (Only have I seen it occur with the Night Light fading; otherwise, the system would produce a hard crash.)

Heat is not much of an issue when just doing a 3DMark run since they're short tests, yet 2150 doesn't pass unlike 2140 FT2.

I just want to be able to play the BO6 Beta while SBMM is turned off, then I'll get an RMA

@GerryB maybe it's not my vram, but still, it shouldn't have the issue I had just mentioned previously.

 

[GerryB]

vram oc-ing is not a guaranteed feature, should not be a reason to RMA
only vram@default clock+timing must work without glitches+artefakts

2150FT2 works with my lower temps@700-1268mV

edit: second Test
also with more Watts my custom Fancurve works enough, to hold the Vram<50°C
(max.Fan in this Case=50% only in TS required, ... but in real Games usually not so much W and rpm)

This card has always had a problem with Tessellation; I don't know why, but I've just dealt with it so far. I still have a year left in my warranty; I just didn't feel like going through the headache of a process and not being able to use my main desktop for a month or so.

2140FT2 works with 700-1262 mV on my card, but in games it will crash after an hour of play.

Do you think 2136FT1 at 693-1250mv would be better?

 

[GerryB]

yes, may be in games the temps are too high after an hour+
and
try 5fps less as FRTC/Chill, this should not affect the minFps but helps the Temps

 

[cra3khead]

@GerryB 2136 at 693 mv didn't work for some reason; I'm back at 2140 with 700; I don't know if there's any other way I can undervolt my card more. My thermal pads must be as hard as rocks or something, because it doesn't even exceed 56 degrees in game. I always have the fps capped to my monitor's refresh rate.

 

[cra3khead]

I'm running 2124FT at 687/1250mv currently, and it seems to be doing better than before. Could you suggest where to go from there?

 

[GerryB]

try 2066ft ... 2062ft at 681/1237 (I don´t know at which clock your artefacts starts with this lower volts)
the most games don´t need the full vram-ocing or the max. bandwidth

2124ft isn´t much faster then 2066ft
only some games can really use more bandwidth, but may be, more games like the better timing (min fps)

681/1231 works with my low temps + safe dpm3=1029

 

[cra3khead]

try 2066ft ... 2062ft at 681/1237

Why don't you use 2070? Since -12 would equal 2058 (the maximum of the tightest timing strap)

Ergänzung (4. September 2024)

2124ft isn´t much faster then 2066ft
only some games can really use more bandwidth, but may be, more games like the better timing (min fps)

Is my score supposed to go down that much? My previous score was 4350 using 2140FT, I believe.

Update: It's not stable; 2124 at 687/1250 mv gets through more BO6 matches without crashing; I can't finish one game with the previous setting. I wish there was a pass/fail test for vram. I'm constantly guessing and having to play games for long periods to see if there's a crash, and when there inevitably is one, I have no idea why it crashed.
