Dell XPS 15 7590 - i7 9750H / GTX 1650 - Thermal Throttling fix on 1.28 BIOS

[Antares23]

Hello guys,

 

So I just got my XPS 15 7590 (i7 9750H/GTX 1650) about two weeks ago and I quickly found out that it wasn't adequately cooled and almost instantly throttled really bad (like 750MHz-1.3GHz on the CPU) as soon as I was playing a game.

When searching about this on Google, the only fix I found was replacing the heatsink with the i9 version or undervolting the CPU. The thing is that mine XPS came with the latest 1.28 BIOS, that means with undervolting and BIOS downgrade disabled.

So until I can afford to upgrade the heatsink, here's the fix I found.

 

With ThrottleStop, here's the settings that allow the XPS to run at around 3.0-3.4GHz on all core while gaming (so, soliciting both the CPU and GPU) without throttling so bad that it make the game unplayable.

The only thing is that the CPU constantly at 100°C in game. But, to be honest I prefer this than not being able to run any games on it. And after all the CPU security on the die itself would kick in before damaging the chips.

I cleaned the fans and heatsinks, and I always raise the XPS so it can get more fresh air.

 

I will also soon repaste it, I hope that this will lower the temp a bit.

 

Anyway, here's the settings:

Enjoy using your XPS to its full potential without throttling.

 

Obviously, I won't be responsible if you damage your laptop, use this at your own risk.

Bye and be careful.

Never trust "temp security" on a laptop - open die isn't safety as desktop with ihs. Yes you can run with throttle stop but always be careful. Maybe use external cooler for slightly better temps as well. Also about bios - i think they are several bios flashing methods to get around your "downgrade block".

 

Also before buying a part for internal hardware such as cooler you said  always triple check to if that is competible. Sometmes they might haver diffrent revisions that can ruin your day after buying it.
