Dell Precision 7540 and 7740 Owner's Thread

Ok. It's just that the published Dell specs suggested they would work.

 

4x4 doesn't refer to PCIe 4.0. It is referring to the number of PCIe lanes that the drives can use. PCIe 3 is about 8 Gbps per lane.

 

Ok thanks for explaining for me.

 

I'm having an audio issue, a static sound followed by a second or two of lowered volume, every 7-8 minutes while having audio playing. I have a 7740 with xeon 2286, rtx 4000, and 4k display. Dell support have decided that it's the speakers and have decided to have someone to come replace them. They said if that didn't work that they would replay the motherboard. I know a few others are having the same type of problem.

 

A few posts ago someone was saying they fixed audio issues by disabling the waves maxxaudio program - have you tried that?

 

I like using waves maxx audio, disabling it seems like a band aid fix. There was also someone that replied saying he doesn't have a problem with waves maxx audio so I'm going to let dell replace the hardware. If the audio is not effected but on only a few then it tells me there's either a software or hardware issue on the few. They had me uninstall and reinstall the latest software, drivers and reinstate windows but it never resolved the audio issue. Thanks for the suggestion.

 

To clarify, the crashes were happening only in the game, but the echo problem with the audio was present in other programs or even just running a YouTube video in a browser. I hadn't realized this audio product was even installed, until I searched on the web for the problem with the unwanted reverb and found that others had experienced the same issue with MaxxAudio.

I also want to reiterate that I don't think the audio problem was causing the crashes -- those were apparently thermal shutdowns which I've fixed by undervolting. About -100mV core voltage has really improved my machine's stability under load. The MaxxAudio driver removal definitively fixed the unwanted reverb, but that app probably wasn't related to the system shutdowns.

Testing with Linux isn't a bad idea, notwithstanding the other factors, and I'll try that if I get some free time (I've got a project deadline at work early next week, so testing time is going to be scant for a few days). As a matter of fact, I would very much like to plug in one more SSD and have a dual-boot system (as discussed earlier on this thread). I'm really excited to see how many folks in this owner community are Linux users. Linux would be my only o.s. if I could choose, but I make my living with the Unity game engine. There is a Linux native version of the Unity editor, but it's still an experimental build, and I can't rely on that kind of code for my workplace. All my other tools are either native Linux already, or (in the case of MS Office) run very nicely in the Linux version of VMware Workstation or Virtual Box or WINE.

 

Out of curiousity what version of the MaxxAudioPro App are you running? I have 2.0.54.0, obtained from here:

It seems a little odd that you need to undervolt in order for the system to be stable under load. What kind of temperatures did you have when the reboot occurred?

 

That is odd indeed. I would urge you to check out @Soromeister's post here. The liquid metal job might be part of your issue. Normally these systems do not thermal shut-down, just throttle.

 

Are all the windows versions of aida64 paid for, or is there a free version as hwinfo, speccy etc?
