Every RTX 4090 Owner Needs To Do This! Undervolt + Power Limit

A BIG Disclaimer I forgot to put in the video:

Just like with overclocking you must stress test your undervolt for stability. Use a bunch of games, and some 3D synthetic stress tests like 3DMARK timespy to ensure you don't suffer from any crashes.

I do -300 mhz on Core, then find .970v in curve optimizer and pull that up to 2820mhz and hit checkmark.
Running stable for over 10 months on RTX 4090 Gigabyte Gaming OC. 2805 mhz is another great value.

I wouldn't touch memory, memory overclocking on GPUs really makes cards unstable and degrades the chip too quick.

How are you getting these high temps I get 55 on my 4090 while gaming

This is so helpful.

I went fron the 3080 Strix to this card. The difference Is crazy!

You have the least annoying intro of just about anybody.

is there no problem in long term when i overlock the memory clock to 1500?

What if try to use PL like 70% + OC Core/Memory using sliders?

um i guess my 4090 xtreme airo that came from zotac is messed up cause it's BASE is the overclock at 2580 and it boosts out of the box without me touching it or the bios saying "we're boosting you" to 2980. I dont understand how this card shows in everything with the base clock as 2580 and boost 2780 then BOOSTS to 2980 (I have logs) without me changing a darn thing in afterburner or firestorm.

60% power limit to 70%, is the sweet spot, 80% does basically nothing. 230-350 watts power usage for 60-70% PL, with little fps loss.

I waterblocked my FE 4090. I just set GPU to use 600wats and overclocked with after burner till stable, uses 450watts with no fans! when running 4k/8k ray tracing. BUT - Then I limit frame rates around 200 so games like Destiny and Diablo barely tax the card/ hence I get good power to performance because it never redlines, not sure the logic works out but seems to offset cons while ensuring I can hit peak OC performance. I would not suggest doing what this guy suggests..., as I can get this card to 35fps on a bunch of games I play 4k/ray tracking and with frame gen and above tweaks I get 70-90 vs. sub 60 stock..... so barely good enough. Jk

Too much useless talk.

bruh jus cap ur fps it ezzzzzz just a waste of pwr 2 go over ur monitor refresh esp if its only 60 u will get lik 200v draw that way

I like how he moves the graphs around just to mess with us. 100% deserving of a dislike.

I'm looking to still run all my games in max setting (1440p), but getting lower temperature. I just try undervolting at .950 @ 2700 mhz with +1000 memory clock and power limit 80% and I have pretty much the same performance than default, but -8 degree celcius with the Benchmark of Rdr2 (yes I know, I love to use in-game benchmark). I think the best, is to keep high frequency, but at the lowest voltage possible. I think .950 is really decent. During the Benchmark, the voltage was .960... I don't know why it goes up a little but, but it's still lower than the default (1.050 I think). I see a lot of people talking about just lower the power limit... I tried and it didn't work. Everything by default with the power limit at 80%, the voltage was like 90% of the time at 1.050 and just get to 1 a little bit. I had average FPS -1, so pretty much the same, but with 1 degree hotter (not a average, I just look the maximum temperature I got during the test).

Those frametime times are pretty nice

Powering back a $2,000 video card is dumb...If the max power limit wasn't desirable then NVIDIA wouldn't have made it available... If you can afford $2,000 for a graphics card then you can certainly afford a few extra dollars for electricity.... This card is intended to be overclocked and powered to it's full potential.... If that's too much to deal with then get a lesser (lower powered) card. This powerhouse isn't for you.... Would you put a governor on a Ferrari? Because this card it the Ferrari of video cards and deserves to be treated as such, period! - You've bitten off more than you can chew. Take it back before your return window closes and get a 3080.

I’ll just keep my 4090 Fe on stock.

Great video btw! I'm trying to set the curve as you showed in the video, but when pulling the dot above the 950mv only that point goes up. It doesn't level everything out like yours did in the video. Were you holding another key when moving the point by any chance?

Can you please explain why you would drop the entire curve down first then spike up a single point where you flatten, it makes no sense to me why not just leave the curve as close to default as possible for stability sake?
