Dell Precision 7540 and 7740 Owner's Thread

Yes, the Waves MaxxAudio App controls the hardware amplifier that boosts the speaker wattage and allows equalization control. I believe the Realtek drivers by default do not turn the amp on, or at least not to the same power level as the App does.

Oh, and I also have Fallout 4 on my Steam installation. I have not played it in a while but I can see if it reboots after 15 minutes with Waves MaxxAudio enabled.

 

TIL. Can this be reverse-engineered to work in Linux? Contrary to popular opinion, I actually like the effect that Waves MaxxAudio has on the speakers: playing music at 30% volume with it left enabled, suffices to fill a medium-sized apartment with music.

 

I just heard some weird sound glitches on my 7740 so uninstalled MaxxAudio. Shouldn't I have done that?

I almost never use the laptop built-in speakers - only headphones (usually bluetooth).

Thanks

 

Anyone..?

Thanks!

 

It's a ground strap. It provides an electrical connection between the drive (via the screw) and the chassis.

While the system will likely work without it, you may emit more electrical noise or be more susceptible to electrical noise.

 

Great, thanks. I'll get Dell to send me a new one then.

I don't remember seeing one on the other three m.2 drives....

 

The other 3 locations are not mounted with a plastic non-conductive caddy. They get there shield ground through their screw / standoff connection to the motherboard.

 

Ah ok, thanks. I couldn't remember, and couldn't be bothered to take the PC to bits to check.

 

Anyone use PCIe 4.0 NVMe M.2 2280 drives in their 7x40? Can a heatsink fit?

 

PCIe 4.0 drives will not have any additional benefit (the system only supports PCIe 3). A heatsink can fit if it is super short, there is some clearance above the drive but not a whole lot.
