NVIDIA RTX 50 SERIES - Technical/General Discussion

Isn't straight overclock basically undervolt (sans a cap on voltage) with nvidia? At every given clock it would use lower volts
Click to expand...
Straight overclock lifts the entire curve, so you lose the granularity of being able to specify what frequency to hit for a given voltage.
It's very far from ensuring you're making the most of your gpu.
Out of the box you might need 1.000mv to reach frequencies your GPU can easily do at 0.9mv.

It's like going under a waterfall just to fill a cup with water. There are better ways.

No, I'm aware

But its so much simpler to just modify one value and get 90% there
than testing each point separately for your desired granularity

For a 5090, you can literally just set 0.91 mv at 2925Mhz, hit apply, and you're done. 30 seconds worth of work.
That will work for everyone (at this point I received no fewer than 100 posts, either public or in private, confirming this range is easily attained) giving better than stock performance, saving power and temperatures. For a card that will last at least 2 years.

Is that a straight overclock? That's so 2000s :P


Undervolt is the way to go. I have my Vanguard at 0.91, 2932 Mhz, +2000Memory. Gets to 15250 in Steel Nomad and about 460w in games.
With this voltage, I haven't seen the vanguard above 62 while benchmarking and above 55 in games.

Had a FE previously and I had a slightly lower undervolt (the one used for the Reddit guide, which I made by the way).

It is. I need to have a little play with undervolting. Do you happen to have a link to your guide?

Maxing out 0.89 or 0.895 (depending on starting curve) to 2827 Mhz seems stable for almost everyone. After that, it's up to you if you want more performance, but it gets trickier.

With a Vanguard my main goal was to have slightly higher performance than the best AIB (at stock), so as soon as I got comfortably above 15000 in Steel Nomad, I stopped tweaking it.

Undervolting is for wimps. Max performance! :D

(Mine is also pulling fewer volts than would otherwise normally be required for my 3250 MHz core clock)

Haven’t gone above 500W so far so I’m alright with that. Might try and tighten it up and go for more overclock when I’m back home.

Offsetting the curve upwards (with the Core input) while checking for stability and then adjusting the power limit to taste is far simpler and achieves exact the same end result in my experience on 50 series. Plus it's easier to modify afterwards, just tweak the power slider for more performance or less powerdraw.

Is there an overclocking thread for the 5090? I have pushed it to 150 core and 250 on memory on the Astral OC and its doing 2970-3000mhz without any issues. Don't want to push it too far but be interested to hear what others are seeing.

You need to test for stability regardless of how far you go so it doesn't make much sense to not go as far as possible tbh. You're not going to damage anything as you're just telling the GPU it needs less power than it's configured to use from the factory. You're not giving it more voltage.

Just tried 0.91 mv at 2925Mhz on my Astral and my Nomad score dropped nearly 900 points to score 14042, compared to .895/2827Mhz score 14933 - Really don't think I can do any better than this setting

What's your score in Steel Nomad?

Have you guys noticed the low wattage while playing AC: Shadows?

With a 5090, Performance is in line with the reviews and youtube videos, but I'm surprised the card struggles to draw more than 400w (even 4k native).

Difficult for games to fully utilise a card with so many cores

If you want you see your 5090 use 600w to 660w then run 3dmark, but in reality not many games will be able to reach this, too many bottlenecks somewhere

I got 15.3k in Steel Nomad at my settings of +270 on core and +2000 on memory (Gigabyte Xtreme Waterforce) but definitely power limited in this benchmark versus what I typically see in games. Pulls the full 600W from the wall and the card doesn't boost as high as it does when it's not power limited. Minus Cyberpunk which similarly draws loads of power although boosts about 150 MHz more than Steel Nomad.

Try increasing your memory overclock. Loads of headroom there generally. There's a way to allow you to do +3000 MHz which I haven't tried but +2000 MHz has been rock solid for me.

For the life of my I can't get the curve to flatten after the undervolt point. I can get some very strange shapes but not flatten the rest.

When you say 2000 on memory is it 500 or actually plus +2000 I thought they limited it to 375mhz
 
On my Founders 5090 I'm struggling to crack 14,000 in Steel Nomad (13,960) with undervolt settings.

My power draw is a good 20% less over stock, but I wonder if there's a limit with what the FE can do as I'm a 1,000 shy of AIB boards it would seem.
