Just been messing with my undervolt, how's this?
Only tested in Cyberpunk so far.
Is the power consumption ~72% of the power consumption at 1950/893mV?
1920 is 1093mV by default.
It seems to be.
What I'm noticing is even though I have the set to a max of 1770Mhz it will still boost to 1800+ depending on the load.
Don't know if that's a BIOS limitation or what.
Exactly - so barely any difference.
All the reviews of 3080 vs 3090 for the same models (i.e. using the same coolers) show the 3090 being maybe 2 - 3 degrees warmer at the same RPM/sound level).
80c seems really hot to me, but it's well within its max temp so doesn't really matter if you're getting the clocks you want.
This is what's making me scratch my head about the temps, his are WAY lower than mine.
have you tested 3080s and 3090s in your own rig?
the card shouldn’t boost over the max clock you’ve set or voltage you’ve selected, unless you haven’t applied it properly in the curve editor.
It was, after a few hours of tinkering I noticed if I say set the core to 17770Mhz, it would boost to 1800Mhz, if I set it to 1755Mhz it would lock in at 1770Mhz, weird, but I now know to set one setting below the frequency I'm aiming for.
It did lower the temps, to around 74c in all the standard games (Cyberpunk 2077/AC Valhalla/Hitman 3), Quake II RTX is good for finding lower frequency instabilities as no matter what you do it won't run over 1650Mhz, usually sits on 1500Mhz, draws 355w, it produces a lot of heat (83c), found it CTD if there's a problem.
I saw Buildzoid's breakdown of the Galax RTX 3090 HOF, seems the MLCC look similar as what mine does
when you lock the frequency it will round to the nearest clock bin which is every 15mhz I believe.
80c is a bit high for an under volt but perhaps the inno3d stock cooler is just shit. lol
This is the best voltage/performance I've found for my card on the gigabyte bios
1965mhz~ locked at 900mv, most 3090s should be able to run this setting on air (with decent fan noise) lol.
Looks like the new 3090 HOF shits on the 3090 kingpin Lol
3DMark Port Royal Hall Of Fame
Cooler is just shit, I ordered the Alphacool block, but there's a 3 - 4 week wait for stock.
So I just have to deal with the noise for now, 75c for 1770Mhz won't kill the card, I did flick a email off to PCCGear again seeing they said they have a "sample unit (Fully tested)", just asked them if they were getting the same temps.
You know what's the most disheartening thing about that chart, the lack of AMD CPU's on the list.
Still kind of backs up the Intel is King of gaming statement
Not many people cool their gaming pc's with LN2 though.
lol @ no18 on the list using a very old Intel Core i7-4790K.....
amd have 4 out of 100 cpus in the top 100
no, 10900k is faster for that particular benchmark that all
As well i have to say, buying 3k gpu and another 1k+1k for mobo and cpu without having a bit of fun overclocking it and bench it, makes no sense at all .
Any 3080/6800xt can do similar fps just comprise with some video settings.
She’s here. Going to be shitting bricks as I’ve never pulled a GPU apart before.
You'll be fine mate. Read the instructions in full first before diving in, then read carefully again as you go.
I was the same back when i had 1080Ti's and tbh it was a faultless exercise. I'm heavy handed usually too
Cheers appreciate the words of encouragement
Like jpw007 said, take it slow, hard to mess it up, I've done a few over the years myself, the NZXT GPU bracket was hairy.
I sorted out the temps, they don't go over 70c at 1800Mhz@65% Fan speed, I increased the bottom intake fan's max speed, worked like a charm.
They are loud, but nowhere near the GPU fans loud, I think maybe these 011 Mini don't move the air through the bottom intake like it's bigger brothers.
Word of advice, before you pull off the stock heatsink, unscrew all the screws then heat it up a bit with a hairdryer. It will soften the thermal paste/pads/putty and make it a lot easier to come off
