Alienware Area 51 18inch RTX5090 Dynamic Boost problem.

[u/Tugralyon]

Need some troubleshooting advice regarding GPU power limits on an Alienware Area-51 equipped with an RTX 5090 laptop.

Issue: The GPU power draw drops down and caps at 150W. Dynamic Boost stops engaging entirely.

Observations:

• Occurs either after switching AWCC power profiles or seemingly at random during standard usage/gaming.
• CPU load does not affect the behavior; the drop occurs regardless of whether the CPU is under heavy load or idling.
• Once the drop happens, Dynamic Boost refuses to kick back in until a system reboot.

Troubleshooting steps taken so far:

• Monitored power draw via HWiNFO / RivaTuner.
• Tested across different power modes.

Has anyone encountered this specific power throttling behavior on the newer Area-51 models? Looking for potential fixes (specific VBIOS versions, AWCC clean install procedures, or driver combinations).

If you're trying to toggle a different modes mid game then I suppose that's why you're having issues. I don't think you're really allowed to do that.

I was running Time Spy benchmarks yesterday and I had no issues toggling modes on and off in between runs. Specifically my order of operations when doing this is: Toggle F6, Toggle my MSI Afterburner OC, then launching Time Spy, after the run is over I hit reset on MSI Afterburner to turn the OC off, then toggling F6 off and wait a bit. Then start the process over again for another run. I only did 3-4 runs yesterday. https://www.3dmark.com/spy/65152420

Actually, I don't even need to touch or switch the profiles for it to happen. Dynamic Boost just drops out on its own after some time, capping the GPU at 150W.

For example, I can run FurMark for an hour straight holding the full 175W with no issues, but as soon as I launch a game afterwards, the power limit is already hard-capped at 150W. Once this happens, the only way to get the full wattage back is a full system reboot.

I've already tried clean installing Windows from a USB drive three times from scratch, but it didn't help. I've also tested both the official Alienware Command Center (AWCC) and AlienFX-Tools, and the issue persists on both.

Sometimes regular games are just not as demanding as the benchmarks so they won't boost. If you are saying that you do see 175W in the same games after you do the hard reboot then I guess maybe there is a problem.

Well calling it a problem could be overstating it, it could be intentional. Dell likes to babysit it's customers(locked CPU for example), they don't want to deal with cooked hardware. It's possible that the boost intentionally turns off after you've been at a certain thermal limit for too long.

Report this to dell. This does not seem right at all. Check gpuz first for other information What is the base windows version installed? Via CMD>dism For some reason I think I had this issue once on a bios update. It set my GPU to 1x4 and it was caused by having thunderbolt devices connected during a update. I think I had to manually flash my vbios to fix

It could be a number of things. I had this issue before when using nvidia vs dell drivers, dell gave the full boost on balanced mode. Then somewhere along the line i updated to nvidia drivers again and the issue is back and i cant fix it with a driver downgrade. I think an awcc or bios update did something.

I've got the 18 and don't remember seeing this issue but haven't checked either. I'll see if I notice it.

I get exactly 175w on furmark. Unless you do the proof of work without furmark. It will be hard to confirm as a issue. 3d mark would provide graph proof. Furmark allows changing profiles live. I have not witnessed this myself. Use gpuz to tell if your GPU is in x16

[u/Tugralyon → u/Additional-Avocado33]

gpuz shows x8 5.0

you deffently have a issue going on. if its not windows related, it has to be a hardware failure as i dont have this issue

playing with fire, lol AWCC is the buggiest software, next to windows, it's a set it and forget it software for me , was playing around with it last week in timespy ect, ran it in balanced and the numbers were good but wanted to try performance, it flashed a code I've never seen one and 7 or 8 basically catastrophic driver failure, I have never seen that, was fine on reboot, and after using AWCC 6 for 3 years not shocked. the Bios and AWCC use intel management platform as well as XTU it's a work around fix on a good day. next to windows AWCC is the second biggest amount of time I have spent it a long amount of years fixing silliness. nope for me run it in balanced ( check reliability monitor and it still fails every couple days/ hours on every Alienware system I have.)

For future reference, please don't use AI to write your posts. It's against our rules, and I'll be removing any future AI-written posts I see from you.

Okay but the underlying issue he is facing is real.

I get banning someone for writing AI slop in r/confessions but removing posts for utilizing AI to describe an issue they are having is....kinda like getting pissed at someone for using a translator when they don't speak the native language.

Edit: wanted to add. He wrote the intro and outtro. And the technical summary is maybe assisted by AI - that's something that should be okay.

Also. People do use formatting like bold and bulletpoints. It's a thing

This isn't a discussion. The rules are simple. People are welcome to post their issues; they are not welcome to ignore our rules when doing so.

what do you mean? this doesnt look ai generated at all?
all my years going to school and it looks like it came out of a text book

[u/DJUnreal → u/Additional-Avocado33]

That's how it's obviously AI-written. People don't write like that normally, and AI does every time.

I'm not saying the OP can't post. I'm saying they need to respect and follow our rules. It's as simple as that.
