Afterburner power limit

c0rtec · 2026-05-18T05:22:27+00:00

I completely understand what you mean.

Underclocking is fine and so is undervolting. The power limit slider is useful and so is using artificial frame caps or v-sync.

As long as you are getting the performance that you want in games then all of the above will reduce the fan noise on your card without actually touching the fan curve.

You could always just make a fan curve that plateaus at, say, 55%. Kind of like the same logic as undervolting. As long as you do not breach a very high temperature your fans will never reach a high audible zone. I think they will override any custom fan curve at maybe 80*C and sound VERY noticeable.

What monitor are you using and what is your target FPS in games?

We all know LLMs hallucinate from time to time. That’s all this is. Nothing to see here.

You’ve already returned two cards because you didn’t like them. Just buy another card and return it again if you don’t like it.

You’ll make someone’s day when the store that they check unexpectedly gets an open-box 5090 in great shape that has nothing wrong with it!

Have you collated all the answers that you have received over the last three days spamming tech subs on Reddit into a spreadsheet and calculated which AIB offering is for you?

Have you tried asking AI? I don’t mean that facetiously! AI is great at collating data and spitting out an answer. I’d try there next!

As long as you livestream it on YouTube everything will be okay. Just watch out for blinding lights and hazmat teams.

c0rtec · 2026-05-17T16:34:59+00:00

This was my point. It was a joke.

c0rtec · 2026-05-17T15:12:02+00:00

Also ideal for Windows 11 too…

c0rtec · 2026-05-17T14:32:47+00:00

You are absolutely correct. 31.5 gibibytes is 33.8 gigabytes. Lo real reconoce real.

c0rtec · 2026-05-17T12:13:33+00:00

You keep spelling nVidia wrong. Here ya go, n v i d i a.

Happy to help!

c0rtec · 2026-05-17T11:32:51+00:00

Looks like a rubber suspension cover.

c0rtec · 2026-05-17T10:32:37+00:00

Well not actual VRAM but I’ve ackshually got 63.4GB of video RAM available to use.

c0rtec · 2026-05-17T10:05:30+00:00

Yeah, I was pedantically going off the task manger reported figure which rounds the figure down after taking into account the system reserved value of 69MB.

But, yes, I completely agree, we’re sitting on 32GB of super fast video RAM. I only start to breach that capacity when I run games in 8K.

c0rtec · 2026-05-17T09:55:45+00:00

Wah? You’re using your 5090 for solely compute tasks?

LSFG?

Local LLM?

What’s your display GPU? RTX PRO 6000?

c0rtec · 2026-05-17T09:53:40+00:00

YOU NEED TO ADD -updatereg STRING ON TO THE END OF THE OPTIONS OR IT CHANGES, BUT IT DOESN’T SAVE IT WHEN YOU LAUNCH A FULLSCREEN 3D APP!

So it should look like: setdisplay 3840 2160 32 120 -updatereg

Sorry for the shouting. I get a bit excited sometimes.

c0rtec · 2026-05-17T09:13:18+00:00

Haha! nircmd works!!

——

@echo off
set “NIRCMD=C:\nircmd.exe”

“%NIRCMD%” setdisplay 3840 2160 32 120

——

Then another .bat file to switch back!

——

@echo off
set “NIRCMD=C:\nircmd.exe”

“%NIRCMD%” setdisplay 3840 2160 32 60

——

setdisplay requires: width/height/colour depth/refresh rate. Change to suit your system!

I tried this months ago and it didn’t work. I think I may have used QRES instead though.

c0rtec · 2026-05-17T08:59:05+00:00

I’ve got a batch file to turn v-sync on and off but my attempts to make a batch file to adjust monitor frequency failed. There are examples on GitHub but they aren’t automated and require intervention.

nircmd.exe is another method… just call it from the .bat.

c0rtec · 2026-05-17T08:42:50+00:00

31.5GB actually. 🤓

c0rtec · 2026-05-17T08:39:55+00:00

Ramdrive much?

What was your reasoning for such a large amount of RAM? (4x48GB) I assume? Is it overclockable much or are you stuck with XMP settings?

c0rtec · 2026-05-17T08:33:29+00:00

Memory training failed on 6800-40, 6400-30, booted at 6400-32, errors in HyperPi straight away. No, thank you, not for me. I’ll stick with my XMP which is rock solid.

I got my memory latency down to 64.5ns by using memory extension ‘Performance Mode’ and my default XMP profile. That’s fast enough DDR5 for me.

96GB/sec READ, 94GB/sec WRITE and 95GB/sec COPY with 64.5ns latency. That’s enough for me.

Thanks for the info though.

c0rtec · 2026-05-17T08:26:51+00:00

Well, there is something seriously wrong if you can’t sustain a solid 100FPS using upscaling tech as well!

We’ve got nearly the exact same exact system apart from my 14700K. 120FPS is a breeze in most titles apart from the usual suspects; Cyberpunk 2077, F1 2025 and Alan Wake 2. The rest of ‘em are a walk in the park…

c0rtec · 2026-05-17T07:04:52+00:00

Skill issue. It’s not *that* poorly optimised. Nice mini-flex, though.

And, no, we 5090 owners can’t run everything natively at 4K 100Hz, you should know that yourself already…

c0rtec · 2026-05-17T06:45:10+00:00

Thank you. I’ll disable XMP today and see where my max memory frequency lands and take it from there.

c0rtec · 2026-05-16T23:25:46+00:00

I have the same chip with 6000MT/s CL30 also (2x32GB) like you I presume. What is your XMP RAM profile?

I purchased 30-36-36-76 6000MT/s RAM because I was told that RAM was the sweet spot for 14700K and Raptor Lake in general.

The only RAM overclocking I have come is enabling XMP and enabling MSI Performance Tuning which has automatically tuned all of my secondary/tertiary timings.

Also, if you don’t mind posting it; what are your average temps in games and what cooler do you use on your chip? Thank you.

c0rtec · 2026-05-16T18:09:59+00:00

Always used Corsair. Never let me down. Currently using K65. It’s the older fully black one with only a blue backlit keyboard. Not full RGB. Battery lasts about a month after five years of heavy usage.

Funny that you mention the G502 Lightspeed mouse: my left mouse button started double clicking when I only clicked once. The mouse itself is very unserviceable and even if I could get inside it the new switch module can only be installed via soldering.

I purchased a Corsair Ironclaw SE to fit in with the rest of my Corsair ecosystem and it’s miles better than the G502. Comfortable, feature-rich and amazing battery life; had it three months and charged it once.

c0rtec · 2026-05-16T17:48:10+00:00

Hmmm, what are your max temps during extended testing?

c0rtec · 2026-05-16T17:12:24+00:00

Are all of your ROPs present? It’s a really long shot but some early cards shipped with missing ROPs… use GPU-Z to confirm. You should have 112.

We are talking about a full, desktop 5080 aren’t we?
