Dell Inspirion 7577

Interesting product indeed. There is no mention of it's potential electrical conductivity though... Would need to know what kind of risks we are talking.

 

I've got a few ideas I've been sitting on for some easy additional cooling I might mess around with today. Stay tuned!

 

Hey @spektykles you never mentioned how exactly you set your FCLK / System Agent clock from 798MHz to 1000MHz. Can you explain for the rest of us please?

 

Optane Support was added to HM/QM170 mobile chipsets if I recall because the 200 series was delayed at the time. You don’t need a seperate slot for it, well other than a free m.2. As far as I know there are only two m.2 slots. It’s not “officially” listed for the 7567 and 7577 in terms of Optane but their HM170 chipset definitely supports it, if it does not work then it’s down to the Dell bios not the chipset.

 

He won't! He likes just to tease us and that's all. He hasn't provided anything at all to us. Stop bothering and don't ask.

 

Meh. Proof or it didn't happen. Idrc, my machine runs great as it is.

 

Got this piece of garbage earlier.

When I have earphones in, it makes a constant hissing sound. It starts when any kind of audio plays, and when ending the audio, it continues for a bit, then stops. The hissing doesn't change volume when I increase/decrease volume and happens with any earphones. It doesn't happen with the speakers.

Also, the microphone has a terrible echo and keeps cutting out.

Anyone know if these can be fixed with software? Or do I need to return it to Dell?

Seen lots of people complain about this (some complaining from as far back as 2014) but some people blame drivers, some say it's hardware, etc.

I can't even use different drivers because Windows 10 keeps installing the same ones and won't let me install others.

 

Judging from your first sentence I'd say return it if you're not happy. I can't answer you on the hissing as the three 7577s that I had did not have that issue. You can google how to disable automatic driver updates from windows updates and see if you can install newer dell or realtek drivers.

 

I had the same frustrating problem for a month after a windows update in march, along with terrible audio quality and distortion
After trying various solutions, I finally installed the stock version of windows 10 by using the media creation tool, and downloaded the drivers from Realtek itself.
Do not install the audio drivers from the dell website.
Edit: In case you don't want to reinstall windows, you can try the solution from the dell forums first.

 

Well I'm just gutted because I paid extra for a Dell, expecting great build quality and I had some issues already, and a keyboard that, while I find it easy to type on, feels really cheap and not solid at all.

I'm downloading ElementaryOS now to see if the audio issues happens with Linux.

 

Thank you, will try this after.

 

That's strange as this is not my experience at all. I installed most of my drivers from Dell's site on initial setup. Since then however, some have been tweaked/updated manually by me. I will have to check with some cheaper earbuds if mine does the same as what you describe. I normally use Bose QC15 over-ear phones when I game and have never noticed any annoying hissing. However I can hear when the audio chip turns on and off (to save power when no audio is being actively played) and it sometimes comes with a small pop or other audible noise- not a big enough hassle for me to want to disable power saving functionality, but I know others hate it. Windows 10 in general sucks at audio processing and it is well documented. Don't be fooled into thinking its always your hardware.

I think the keyboard on these 7577 is rock solid, unlike my last HP that was all plastic and flimsy. My only wish is that the keys themselves were larger, but then again the extra space between the keys is helpful in feeling where one ends and the next begins... so that's really just personal preference.

Let us know how Linux sounds. As I mentioned above, my audio issues are non-existent on my Windows 7 install on my 7577. I also have Ubuntu which I have not noticed any funny audio quirks on either. Windows 10 is fickle when it comes to drivers / kernel scheduler / audio buffer / cpu latency.

 

My only point of reference is my god awful 8 year old laptop, so I'm really happy with my purchase. That audio issue was a major source of frustration though, as I had already installed loads of media/apps 2 months before the update that ruined it.. So wiping the system was my last resort.
Let us know how the audio works on linux.

 

The Realtek 6.0.1.8219 driver caused the problem for me, if that helps. The older drivers that were previously on dell (November) worked fine.
The audio quality felt like it was coming from a tin can, not just the hissing.
The intermittent audio pops only came up when I switched to the default windows audio drivers, but the sound quality was still not up to par, until I reinstalled the realtek drivers manually.

 

Lol, that's kinda funny, as that is the version of Realtek driver I have installed and been just fine with. I may have to check out some more recent updates and see if I like them more.

 

Same issue with ElementaryOS

With Elementary, it constantly happens though. It doesn't go on and off depending on whether music is playing. It's quiet, and doesn't get louder when you increase volume, but it's just loud enough to really bother me.

I have a new SSD arriving soon, I will reinstall Windows and try to install other drivers, and maybe even try Windows 7 just to rule out software.

 

Also just noticed the hissing sounds happens with the speakers too, not just earphones (it just isn't noticeable until your put your ear right up to the speaker)

Still hisses, then cuts out after a few seconds of sound stopping.

 

If you're positive that is the case, then you may have a slightly faulty (manufacturing defect) audio chip or a ground loop isolation issue (shorted/pinched wire, incorrect routing, poor internal connection somewhere, or other piece of something touching something else it shouldnt).

Have you messed with the stock Win10 audio sampling settings at all? In my experience setting them higher than stock actually yielded poorer audio thanks to Win10 and W10 drivers involved.

 

@Maleko48 I need your help. I also have that sluttering sound issue in windows 10 however no issue is there in ubuntu. Can you give me your modded drivers? Currently drivers installed are from dell dated Nov 24.
Usually sluttering occurs on laptop spekers while playing games, on headphones its fine though. However when listening to music and performing multiple tasks(usually using windows specific things like opening explorer or settings) there is slutter on headphones also.


Thanks

Try any other distro like ubuntu or budgie. Elementry is having some issues with our machine. My system only lasted for 2 hrs using elementry and temps were constant at 70s.

The same situation in various installs and even after applying all upgrades.

Give others a try first.

I have had similar experiences on stock install of Win10. It's going to come down to clock speeds, latency, drivers, background programs/processes/tasks/services, and sampling settings.

Have you cranked up your sampling settings at all at the Windows level?

Have you tried using RevoUninstaller to completely remove the driver and reinstall newest version?

Is it more exaggerated and noticeable when you unplug and run on battery?

 

No such issues here.

I hope you did a fresh install without that Killer SmartByte crap that comes preinstalled. That can cause audio stuttering in streams and also due to DPC latency spikes from it.

I always do a fresh Windows install and make sure no vendor (ie Dell, Asus etc) branded software is installed. GPU/WiFi drivers I get directly from Intel/nVidia and if Audio problems occur I get audio drivers from Realtek directly. You can also use the audio drivers from the 7588 as it’s using the same chip, not to mention those drivers have WavesMaxx as an optional install which I like and I don’t have to have WavesMaxx installed. (Realtek ALC3246 aka ALC256)

 

Yes

No

Yes



What do you suggest?

No smartbyte, and dell related stuff except Dell power manager.
Can you link that Realtek drivers here?
Thanks

I use the latest ones for the G7 on Dell’s site as it’s the same ALC256 chip (remarked as ALC3246), just use the support site to select the G7 driver list.


For stock Realtek: http://www.realtek.com/downloads/do...=24&Level=4&Conn=3&DownTypeID=3&GetDown=false

You might find even newer ones on Windows Catalog driver site (Microsoft’s site).

 

I think G7's are latest.

OK I installed G7's drivers and now audio is much better, in half an hour observed only one sluttring(while typing on store) that also never happened next few times on recreation.
Thanks @Aivxtla

@Maleko48 I am still curious about the third question you asked.
Thanks

 

For the record, the method Im using is illegal and will be patched soon as it went public. Both Dell and Intel will jump their ass on the sky....I cant disclose it right now...
This machine using Intel Boot Guard and locked ME region, so u cant write anything or flash custom BIOS...until now...
The latest signed ME fw for 7577 is 3425, I modded with 3460 hacked.
If u want proof, here it is

The only 7577 with hacked ME FW so it will allow to change all parameters the system allow (except basic things like multipliers on non K CPU). I also modded the Thunderbolt 3 FW (NVM33) with Power Delivery so it allow to charge the device via powerbank....

 

I'm not sure how much of what I'm about to tell you applies to the newest G7 drivers, but from when I did a lot of research and testing of my own while looking into the stock audio driver issues of the 7577, I determined that there was a system-wide latency/Win10 CPU scheduler issue linked to the audio problems- it was acting like there was not enough of an audio buffer to turn the sampling up past stock Windows 10 values. To be clear the audio issues are non-existent on Windows 7.

From the research I came across online, many people pointed to dynamic clock scaling (TurboBoost, SpeedStepT, SpeedShiftT) and power-saving (C states/Windows 10 being too aggressive to save power in other areas of its management) features causing the problems to be exaggerated further. The people complaining who were especially sensitive were those trying to record professional audio streams or making music using software, etc followed by gamers and then average users. The easy solution for many of them was to simply run their CPU at maximum clock speed full-time and turn off all the above mentioned power saving and dynamic features since Win10 couldn't seem to cope with them appropriately at its core.

The audio drivers and drivers in general for Win10 have long been a pain point for this machine and many other Windows 10 machines since it is not an issue exclusive to Dells only really. It does seem to coincide with Realtek more than most other audio chip/driver manufacturers.

I also noticed when trying to reproduce these problems, that Windows audio-feedback responses actually fare the worst. For example, when you left click the audio speaker in your tray and drag the slider up or down and let go of the left click, Windows responds with a little dinging sort of a sound. That dinging response sound is where you will hear the crackling and audio disturbances the most (along with other Windows-based audio feedbacks). I usually use my function media/hotkeys which avoid those annoying Windows dings and responses so I haven't thought much about the underlying crackling issues I noticed were present. Another way I was able to reproduce these annoying quirks was by streaming audio on YouTube and turning my power saving slider to maximum power saving and then loading new tabs on chrome, opening and closing heavy programs, minimizing and maximizing windows, etc. Again, it all pointed to lack of sufficient audio buffer and Windows 10 scheduler not prioritizing audio enough. It is most exaggerated when the sampling rates were turned up to their maximum too.

It's hard to say what all else you could do or what I have done to improve mine so much on the poor drivers since my machine is tweaked in so many areas. One that could help you out though is to use Process Lasso and tweak the priorities of your audio-related services/software. If you turn the audio sampling rate back to stock, that will also get rid of the more frequent crackling issues (especially when on battery). You could also try using LatencyMon to track down problematic drivers causing high system latency. For mine it looks like the Microsoft ACPI driver is the biggest offender. There are probably some problematic Windows 10 services/tasks/settings that you could tweak as well, but those vary so much its hard to put a finger on which ones specifically.

What SSD do you have and what drivers are you running for it? I have Samsung SSDs for both my drives and use the Samsung NVMe driver rather than the default driver. Also I have my SSD in AHCI mode with its sleep settings modified to "Lowest" in order to achieve sleep states deeper than C2 which saves a good bit of power and consequently increases battery life a decent bit. There is an entire thread about how to achieve proper deep sleep states and many new laptops need the mod to achieve proper sleep states- including mine.

 

Mine is some SK-Hynix 128 GB ssd and I think the drivers it uses are built in within windows as no separate drivers are available at dell and OEM site.
However G7 drivers without Maxx Audio are working best for me.
The built in Realtek drivers(windows update ones) are still old and have low volume issues in applications other than windows.

That's exciting. I'm going to be updating mine as soon as I get the chance.

 

Installed those newest G7 drivers last night and haven't noticed any difference in audio quality / volume / crackling / etc. If I turn up audio sampling from Windows' setting it crackles all the same. Still unable to go past 24bit @ 48KHz even on highest performance settings without getting crackling, even with all my tweaks. I had Overwatch running and ALT+ESC to get my mouse over to my other screen and just the act of clicking and grabbing a window to drag to a different spot on desktop causes the audio to crackle like hell, especially when actually moving the window while I've got my left mouse click being held. It is a Windows 10 issue as far as I am concerned...

 

I haven't checked sampling. I think it had been restored to stock when new drivers were installed will check them asap and report you back.

is there anyone success to turn on fastsync option? i heard that when the external monitor connected, igpu turned off and dgpu connect directly.
i tried this, but still no fastsync option

 

You've got to use the NVidia Inspector tool to set the FastSync option. Not too hard to do. I've been using FS on mine.

 

Should only work for the DP, not the HDMI.

 

You'll soon be able to add me to the list of 7577 owners, just ordered a scratch and dent one from the outlet. Got the 4 year warranty, which means I'll be getting 1 or 2 free upgrades over the course of 4 years.

 

Hi,

It's nice to meet you all.

I've been having Dell 7577 laptop for 2 months now and having a basic warranty. However, i am now working overseas ( in Indonesia, if there's any user from this forum that has been or in Indonesia,) and i want to extend my warranty to premium support , but there's an issue.

My account is on hold, and Dell representative from email said that i couldn't make any purchase if i my account still on hold. I've tried to phone dell verification team from here, Indonesia, for several days now and still cant get through them.

Is there anyone here that have same issue ?

Dell 7577 should come with Premium warranty by default. That's strange.

 

Those bought in US before Jan didnt have premium warranty.

Dell is offering me a system exchange due to issues they had trying to repair my 7559. They are offering this model with the following specs and I need some opinions to see if they are the same as mine. Thanks.

 

I can’t see the image but it doesn’t matter as even the base model (GTX 1050Ti) of the 7577 has a better GPU than the 7559. Even if you get the Core I5 version it isn’t much of loss.

I had a refurbished 7567 with 1050TI, 1080P IPS, 8GB Ram and a 1TB HDD. I complained twice about uneven core temps and they replaced mother board and mailed my SSD back in a package and the put a new HDD because the model only came with a HDD standard. So I got a free HDD lol. Anyhow sent it in again for the same uneven core temps and I asked for a 7577 as a replacement and they gave me within 3 days, the maxed out version with 4K IPS, I7, 512 GB nVME SSD, 1TB HDD, 16GB Ram and a GTX 1060. Then they mailed the HDD from the old one back too so I got two free HDDs total that I didn’t ask for as well lol.

Basically what I’m saying is they can be pretty generous depending on how well you communicate and how polite you are. Dell definitely has the best coustomer service I’ve seen in the PC business, not many replace a $700 unit with a $1,300-1,400 unit. They call regarding each step of a repair and call to ensure the product you revised is working well, at least in my case.

 

I fixed the image issue so it can be seen now.

 

Go for it.

Pretty much close to the same replacement as mine. Go for it, its a major upgrade and it’s the top tier version of 7577.

 

Thanks for the replies. I accepted it.

I just have one question. For people who've had both did the battery not being as strong in the 7577 make a difference?

 

My 7577 gets here next week. Is a clean install recommended, or is Dell bloatware easy enough to just uninstall without going to a scratch Windows install.

 

Clean install recommended. Install audio driver from G7 and all possible available drivers from OEM. Others not available with OEMs can be installed by dell's support page.

Ordered the 7577 ($727 after tax ) and it should be here in a few days.
Are there any 144hz panels I can install on this thing or should I just go for a Chi Mei 120hz TN? (hear you can adjust the brightness on those)
