3080 Undervolting

Vigorito · 1 Oct 2021 at 13:38

Combo suprim x + arctic II 280 cant fit into air mini with rad front ,but thats not the conversation right now,coil sound its not that bad when i close the case i cant hear it,also if im not satisfied with new gpu its a easy sell on classi. In under 1 hour

1905 @ 882mv here on my profile 4 (the one I use mostly). Matches out of box performance with huge temp/power drop.

Some can run it less volts, depends on silicon quality.

Also can do 1830 @ 850mv, which is even nicer power drop for very slight loss of performance.

Yes with lowering PL i read somewere that power draw of gpu is going down,not sure what is happening with voltage/clocks

Reducing voltage reduces power consumption at all 3d loads.
Reducing power limit also reduces power consumption but only when power would be over cap, thats because this is not a undervolt, you are merely just capping the max power, so you will get less performance vs undervolting at same power draw.

my 3080fe seems like a donkey at stock , temps seem fine highest is like 75c but boost doesnt seem great guess thats silicon lottery highest peak at stock I've seen is 1950mhz mostly hanging around the lower 18XX range I've seen few videos of others 80FE at stock using same applications having higher clocks, but with undervolting at 1905mhz @893mv been few weeks seems stable and performance has much improved over stock now mostly sustains 1920mhz with temps struggling to hit 70c at it most stressed

Seems odd to me to be choosing our GPU based on the case in this climate.
Getting a coil-whine free quiet running 30 Series card is gold.

Still, your yet another person to confirm that the Suprim X is very quiet, and coil-whine free. Not seen anybody complain of whine on those. Its the card I really wanted, but never been able to get. Had the chance to buy a 3080 Suprim X for £950, and turned it down back in January.... wish I had taken it now!

Anyway, good luck with your card.

I had a MSI suprim x 3080 with the worst coil whine of any card I have ever had. Thought it was PSU and got another and it was still there then I realised it was the gpu. It was really really bad.

Ive noticed when restarting computer without having MSI afterburner loaded the underclock remains :eek:

not sure if the custom fan curve remains

Seriously? About to try.

I wouldn't worry to much about clocks as the difference between 1950 and 2050 is about 2 fps anyway.

I noticed this. I quickly decided to leave mine at 1905 @887. Card has so much power for 1440 I don't see the need.

I think this is the first card in 25 years I've personally very quickly concluded there is no point bothering. Other than the undervolt benefit of reduced heat.

Yeah I know its just when I compared to others 80FE cards that seem to be boosting higher and averaging higher clocks at stock these are just normal buyers and shows at stock benchmarks being slightly lower , I dont compare to reviewers pretty sure they get the best binned cards

doesnt really matter with undervolting

yeah will check later if the custom fan curve stays , although I do like seeing the info top left so probabluy have afterburner loaded anyway

uscool · 2 Oct 2021 at 12:26

@lnoton doesnt keep the fan curve

neither works for me after reboot. I disabled msi from starting. and then simple started rtss and hwinfo and looked at the readings. back to 1.025v @ 1930 lol

strange just worked for me didnt do anything extra other then loading the saved undervolt profile, Will end up using msi afterburner anyway for the custom fan curve and to show stats

Oh no!

What did you replace it with?

I was kinda out-of-the loop for about 5yrs, my last new-build having been a 4790k & GTX970 system. Back then I don't recall 'coil-whine' being so common? My card didn't whine except at crazy high menu FPS, and neither did any of my friends systems.

This generation, it seems every other card whines! And with the shortages, its impossible to 'just pick the card you want'

uscool · 4 Oct 2021 at 13:11

I had coil whine on cards before but nothing to the level of the 3080fe which I returned the replacement also has it but not to the same level

Large part of the FE cools whine I think is really down to mounting pressure, or lack of. Replaced about 5 FE cards with waterblocks now, prior to waterblock most had whine, after absolutely silent, even at higher clock speeds / FPS thanks to running cooler and getting that extra headroom. Think the extra pressure on components really cuts down on ability to vibrate / move.

Thats interesting, and surprising. Do the waterblocks really bolt on that much tighter than stock coolers? OR do they put pressure on the coils to stop the whine more?

Both my FE's have whined... and after sorting the pads, the whine is now the loudest thing in my system. If putting pads on some coils sorted it... that would be awesome.

uscool · 4 Oct 2021 at 13:50

interesting I was thinking the whine would be more noticable water cooled , the fans somewhat drown out the whine

Hard to compare with the mounting pressure and how much replacing pads with stock cooler would help, not tried it myself (replacing pads and putting stock cooler back on). But with waterblocks, I found, the EK FE ones I have used for 4 and corsair block for fifth, in all cases the block did feel very tight to the point I initially blocked my one first GPU (with EK one), used longer screws thinking the short ones the block came with could not have been correct (they were) combine that with the thermal pads covering the core stuff very well and I suppose prevents components from vibrating which is what causes the whine. My primary 3090FE whined slightly (other ones more) but once blocked, cannot hear any coil whine.

Well if the whine is down to some components vibrating freely or easily, if the block as I suspect in conjunction with thermal pads covers those area's preventing the parts from vibrating, then is why the whine is reduced.

All that said, only been able to block 5 cards, but in all cases, gone from slight wine (my own one) to a decent amount of whine on others, to now whisper quiet pretty much.

Where all 5 cards FE models? And its impressive that in all 5 the whine was gone after fitting a block. I was put off even bothering to consider water block route for my 3080FE, as I figured no point removing the fan noise if all Im going to hear is whine.

Would be great to find the exact components that emit the whine... but cant think of a way of doing that. Sadly no useful internet result either.
