Dell Inspirion 7577

I am using Targus City Gear 17.3". It offers a lot of space and good protection with dedicated pocket.

 

So this laptop runs plenty cool, but I opened up ThrottleStop to see what it was doing. I just can't get thing to max out the CPU with TS Bench. It's not throttling, but it's only pulling 17-18w during the test. Windows performance shows 100% Usage. I'm surprised it's so low. Runs at 31x99.768 during the bench.

EDIT: Running some games and monitoring things, it looks like it pulls a load and acts normal. Disregard my last issue.

 

Anyone has tried newer drivers for the Nvidia 1060 Max-Q? The ones from DELL's website are very old...

 

Sure, simply install the Nvidia ones.

 

Well, it seems that my unit with i5-7300hq and 1060mq runs nowhere as cold as the one tested at notebookcheck. With only Prime95 maximum heat testing it hits thermal throttling. I tried changing paste, but it didn't help much. Undervolting only makes it last longer before hitting 96C and I tought this laptop should be pretty cold while running at stock settings...

 

Checking your paste and pads again. One solution is replacing original VRM pads with thinner pads. You can take a look at my post here: http://forum.notebookreview.com/thr...ls-pics-of-internals-optimizing.811380/page-9

 

The drivers from Nvidia's website won't install....they go into failed state....tried Express upgrade, Custom with full cleanup, no go!

 

Use GeForce Experience app to update your drivers.

 

No, that did not work either, since GeForce Experience app won't install, even after a previous driver wipe.
DELL drivers install just fine, only the ones from the nVidia website do fail, checked multiple versions.

 

I use GeForce experience to update my drivers. I don't know why you're having issues. The only thing I did was clean install Windows 10 pro x64 when I got the laptop.

 

Try clean Windows installation (no factory image!).

 

I am already on a clean Microsoft image, since my laptop has been shipped without OS. Guess I will wait and see which drivers DELL comes with next....

 

After installing Windows, did you manually updated drivers with those from Dell site? If so, maybe try reinstalling Windows, let it download and install all drivers by itself and then just try to use GeForce Experience.

 

Anyone else here have a model with a panel which is identified by HWiNFO as
Monitor Name: BOE [Unknown Model: BOE06CB]
Monitor Name (Manuf): NV15N42 [DELL P/N: RMJCY]

How does it compare to the other panels?

 

Hey there,

I'm having an issue with my toshiba nvme drive on my 7577. Games seem to be loading extremely slow. Especially PUBG seems to take much longer compared to my friends SATA ssd's.
The nvme that I use is the one that shipped with my system: KXG50ZNV256G NVMe TOSHIBA 256GB.
I'm currently running the drive in AHCI which seems to be recommended. My crystaldisk results are:
https://prnt.sc/mzffz4


The loading time for PUBG is around 1 min. Same counts for Apex. I dont notice any slowdowns in normal usage. System feels snappy and performs as it should.
Is anyone else having this issue? Is there a fix? I feel like the nvme should be blazingly fast at loading content. I'm glad to do any suggested tests when asked.

Kind regards

 

I'm very interested in your test results too. I have the same 256GM nvme m.2 drive in AHCI mode in my 7577 and think it's also on the slow side, although adequate for my needs. I still toy with the idea of replacing it with a 512GB nvme m.2 Samsung drive from time to time.

 

Something else has come up. I contacted Dell Support and we did some diagnostics. And now suddenly my write speed throttles like crazy. Write speeds go down to 10MB/s(!!!!!) after 5 seconds of writing. Reboots dont make any difference. I'm really scared for the drive failing on me, making me lose all my programs and stuff. Im making backups as we speak. Does anyone know what may be causing my trouble? Read speeds are normal as they should (2500MB/s).

 

Has anyone tried using type c headphones?
Those are working on MSI and Nitro 5 without tb3 but not on my 7577.

Hello all how are you? I am a bit stumped here as I applied liquid metal (thermal grizzly conductonaut) and changed out the thermal pads to .3 FujuPoly Extreme pads. I used acrylic conformal coating and super 33+ tape so I do not believe there is a short as i double checked with a black light to make sure that everything was protected before i put on the tape. This worked fine originally but, I was worried that .3 would not be thick enough, so I opened up the laptop again, and applied the same type of thermal pads but a 1.0 on top of the .3. After I did this the laptop would boot up fine but after 10 min or so it would freeze up and I would have to reboot, however, temperatures are fine. I got worried that maybe 1.3 was too thick so I am waiting on .5 pads, I regret second guessing my self. Also, only half of the keyboard is lit up, but the ribbon cables look tight. Any ideas on what could be going on?

 

I'm on my 2nd 7577 with a UHD screen which I received Friday. The previous one which I received in July of 2018 was a warranty replacement for a 7559. The first 7577 had to have it's screen replaced not long after (looking at the specs on the Dell site it was a AUO20EB too) and the one installed was the Sharp SHP1450 panel which is what I've been used to. I say all of that because the 7577 I just received came with the AUO20EB (B156ZAN) panel and the difference between the two is considerable. If the saturation option was still available in the Intel settings this whole issue could probably be solved.

The only way I've been able to get the washed out appearance tolerable was to turn the brightness down to minus levels in the Intel Graphics Command Center and install an ICC profile I found mentioned here. I was wondering if anyone else who has the same screen ever got theirs to a point where the colors were pleasing to your eyes. I'm still not exactly happy with the color situation after spending most of the weekend and some of today trying different a couple other profiles, settings and tips found here/elsewhere. After getting the screen replaced on my first 7577 that was one of the only things I didn't have further issues with so I'm not an obsessive person regarding screen settings even though it feels like I'm coming across that way.

In the past when I've received warranty replacements it's usually been the next model up. This time they shipped the replacement 7577 with the same specs from the Tennessee refurb warehouse a day after telling me it was being processed. This time I didn't get to say if I was happy with what they were going to send when I've gone through this in the past. Did they stop doing that?

The reason I was apprehensive about another 7577 is the first one needed a new screen, touchpad, keyboard, motherboard and then another touchpad. When the touchpad was replaced in Feb. the guy had a hard time getting it to work correctly because tightening the screws the way they were supposed to be caused the touchpad to act like it was stuck in the being pressed position. Trying to use it caused that blue square thing to happen when the touchpad is pressed while running a finger across it. (Hope that makes sense) He found a way to remove a couple un-needed screws which relieved the pressure which made things go back to normal. In July I needed a new keyboard which turned into a motherboard replacement that had to be done by the depot (it threw errors after the tech replaced the keyboard in my home and Dell ordered him by phone not to do anything else to it and to give me the case number they provided during his call to them).

When it was finally shipped back almost two weeks later the touchpad was doing the same thing as I described before about acting like it was stuck. I gave it a little over two weeks to see if it might loosen up which it didn't. While it was at the depot they tried to say I damaged my laptop because some screws were missing which still doesn't make sense. The laptop had been stuck as being in the warehouse for about 5 business days before the notice on the site about the repair not being able to proceed. The same guy from Feb came out in Sept to replace the touchpad again. I told him about the damage accusation so this time he tried getting the new one to work without removing those screws which resulted in the touchpad only working with it being loose and making a really loud clicking noise when pressed so much so a friend could hear it in the kitchen from the living room. It was two replacement touchpads acting the same way. I'm scared if this replacement needs a new one that whole drama will restart. The old 7577 was starting to act the same way it was with heat issues and fans always coming on before the motherboard was replaced. I was starting to have anxiety somewhat about what was going to need fixing next especially since the original 7559 warranty is up in Feb of next year.

I probably shouldn't have explained all that's happened since it's so much to read. I have a hard time condensing stuff to a point where I feel there's enough explanation. I'm hoping people still check out this thread.

 

Has anyone had problems with DPC latency on their Dell Inspiron 7577 and mouse freezes/stutters? I've been having problems with it, and it's crashing Monster Hunter World for me.

 

Cant say ive had any issues with the mouse

 

It's more like a system-wide freeze/stutter. Some people say "uninstall SmartByte" (done), drivers are up-to-date, etc. but I still have the problem.
Latest thing I'm trying is disabling all Dell-related services (DPC latency monitors still show spikes, though I have yet to have one of those freezes.... here's hoping)

Other places I posted about the issue:

no issues on my end. I would suspect something installed on your system.

 

Did you ever get a resolution or fix for this issue? The replacement 7577 I received late last year has started freezing as you described. I reinstalled Win 10 last night and was in the process of setting everything back up when the freezing started again while just doing normal web browsing and watching a video. It does it even if I'm not watching a video and it doesn't matter which browser I use. I've done the tests Dell provides and none of them are finding anything. I had to have the motherboard and hard drive replaced this past January and then later in the month they had to send me a new memory stick because one of the two provided went bad.

Now I'm back to being nervous and uncomfortable about using this 7577 like I got with the last one because of them having so many issues that start while just doing basic stuff online. I just want to be able to use my laptop without having to worry about what will go wrong next. It honestly sets me on edge especially during these times.

 

I've started having freezing issues similar to yours. I don't really game on mine so I can't comment on it happening while gaming. My freezing is concurring when I have any browser open at random times. I've tried just about all of the fixes you have with no resolution. I finally decided to reinstall Windows yesterday thinking that would fix things but it didn't. My issues started at the beginning of last week out of the blue. I thought it was just my browser at first so tried other ones and the same thing happened no matter which one I've tried. What's weird is it happens no matter what browser I try but while the browser is freezing everything outside of it seems to be ok. I'm just waiting for the BSODs to start though. That's what occurred with my previous 7577 those started and everything went downhill from there.

 

I think I've managed to improve the situation, though I'm not sure if I've solved it. I used Services.msc (or Process Hacker, which has a searchable list of services on the PC) to search out everything Dell related (e.g. Dell Support Assist, PC-Doctor, crapware that came with the PC for "diagnostics") and set startup type to "Disabled". This improved my DPC Latency a lot (check with https://www.resplendence.com/latencymon or https://www.thesycon.de/eng/latency_check.shtml). I haven't noticed any stutters or freezing since disabling these services (well, maybe once or twice when loading a heavy webpage or program all of a sudden). Notably, I'm still runnning outdated Win10 v1709 and am now running Nvidia drivers v445.87. I haven't had the courage to test whether my PC bluescreens when playing MH World again yet.

Try disabling all Dell-related services and see if that fixes things.

My latest problem is COM Surrogate keeps crashing (don't know what to do about that), which might be related to Intel video drivers. dunno.

 

Hi I've started having thermal isues on my 7577 (with i7-7700HQ and Nvidia 1060m). While playing BF5 on low Settings, i get major frame drops at around 44 fps and CPU temps at 90°C/ 194°F. I believe i have the most recent drivers installed.

When i set the maximum CPU power to 99%, to prevent turbo boost from running, i get around 54 fps and CPU temp around 80 °C degrees Celsius, which is a bit more playable. Is this normal? Do you think i should open it up and repaste ? I have the laptop for 2.5 years now. Turbo boost seems to push it too far..

 

You should definitely undervolt it and a repaste helps alot but is a pain with this laptop as you have to totally disassemble it. Disabling the turbo is also a good solution, games don't benefit really anyway.

 

Okay, thanks for your answer! I will try repasting this thing and post my results. I am not sure if undervolting really helps or it just delays the inevitable throttling but i might give that a go as well.

 

It helps alot. If i remember correctly i could manage -0,080V and it gave me 8C better temps in average.

 

Well i am now undervolted at -0.113 and i also re pasted everything. From a brief test i have around 77 Celcius with Turbo boost on now while gaming! Also ambient temperatures here is 37 Celsius. Pretty impressive difference, i recommend this to everyone with temp issues.

 

Hi, I've been using the Dell 7577 for about an year, it was flawless in the beginning but now im facing some issues. First of all the battery performance has dropped quite a lot. The battery report shows Full charge capacity of about 28,242 mWh. I have tried draining out battery completely and recharging it but that only improved it to about 32,133 mWh.
Secondly some of the keys on the keyboard stopped working, some keys such as p[;wsx2 . They do work when I apply some pressure on the keyboard area. I've tried disconnecting and reconnecting keyboard ribbon but that didn't work. I don't have dell repair support in my country and the laptop is not in warranty. Anything that can be done I have to do it myself. Any suggestions will be appreciated

 

You can get the Keyboard easily on Aliexpress: https://www.aliexpress.com/wholesal..._20200518233032&SearchText=dell+7577+keyboard
You have to disassemble the complete laptop, or let a computer repair shop make the work for you.

You could also exchange the battery easily, it is also available for buying.

 

Hello everybody.
Recently, I change thermal paste and the temperatures have dropped dramatically but one temperature sensor is getting above normal.
The sensor is the "DIMM" and it is heating up more than GPU and CPU. I don't know if I forgot to put any thermal pad in right position. In addition this sensor is not from the computer's memory, but from the VGA.
Any suggestions on what to do or is this temperature normal?

Looks fine to me. It heats up because of the surroundings and transferred heat from CPU, GPU and VRMs.

 

Hey I'm running into a problem with my 7577.
My computer is stuck at the dell logo and just started this, yesterday. I tried using the diagnostic in the f12 menu and don't get any errors. I have two hard drives and both show up in bios. When I removed the second one, it booted right up. I checked connections and everything seems fine. I put the second HD back in and booted from a usb win 10, I don't see the second HD. I tried using the bootrec commands after bootign from the usb but get an acces denied on the bootfix command.

Is the HD really bad, I just went back and did another thorough diagnostic test from teh F12 menu and it passed.

Thanks for the help in advance

 

Yes, it looks this way. You could start a livelinux from a USB stick with HDD scanning tools to check the HDD ( https://www.system-rescue-cd.org/) or put it in a 5$ USB hdd case and try to check it after booting.

 

There's a new BIOS update from June 5th available in case anyone didn't know.

 

It was a couple years ago since this was last mentioned so I just want to confirm that purchasing
DDR4 2666MHz ram would likely be a waste of money. The Crucial site lists the higher than 2400MHz options being compatible then when I look elsewhere it's mentioned that going over that wouldn't really be beneficial.

 

If you want more than 16gb of ram, You will have to move up to higher clock speeds on the ram. But correct, buying faster ram for the speed is no need.

 

I was debating between the 2400 and 2666 last night then second guessed myself even though most of what I found says the 2400 would work fine and that anything over would downclock. I'm not new to purchasing ram or computers but 2400, 2666 and 3200 being options after looking up ram options on Crucial's site with the model number had me wondering.

 

I am in the same boat. I am boosting my laptop to 64gb of ram and a new evo 960 2tb ssd. I have to purchase higher clockspeeds than what I have now, but it will just run at the fastest that my notebook will allow.

 

I think its better to use 2667MHz since Dell will not allow to POST. You could try 16GB 3200MHz or 2800MHz but for 32GB+ BIOS will fallback to 2667/2400MHz.

 

Hey guys, it's been quite a while since I have checked in on the forums.

My 7577 wasn't running too crazy hot or anything, but definitely not as cool as when I first bought it, so I finally cracked it open to clean out the fans and do a re-paste in addition to upgrading to 32GB ram (2 x 16GB).

Only problem is I forgot to check my core temp differentials prior to the work I did. My temps overall are fine, certainly improved, but I can't remember if my core differentials were always so high/variable. At idle the delta from lowest to highest core seems to be about 5C. Under heavy synthetic loads such as Prime95, there seems to be about 10C sometimes hitting up to a 13C delta.

Either way, zero throttling from both CPU and GPU after running Prime95 and Kombustor stress test "(GL) msi-02 (PhysX4 GPU - hard @ 3840x2160) simultaneously for 90 minutes. My GPU temp very slowly climbed towards 80 but never quite made it to 80. My CPU was pushing around 88-89C after the heat soak had a chance to set in. MSI Afterburner was showing about 42-44 watts power usage for CPU (-145.6mv UV) GPU was basically at 99% usage the entire time and CPU was at 100% usage the entire time.

Unfortunately my fans still like to stay running when I am just doing my usual desktop stuff like internet browsing, Discord, some coding, etc... Maybe it is finally time to mess with that dell fan utility I have toyed with once or twice in the past that one of our members here has a thread for. (FWIW, I run my 7577's 4k screen @ 1080p 100% scale, I have a main 4k monitor that runs at 4k, 100% scale via HDMI, and a 3rd sub monitor @ 1600 x 900 running from a USB-C dongle with an HDMI port on it. I have my GTX1060 always on and running my desktop because it is snappier that way. I set my Throttle Stop profiles up as if my machine were a desktop, so I know all of the above contributes to fans not wanting to shut off.)

Right now I am idling at 56C GPU /54C CPU with the fans at 3000 ish RPMs while typing this. Since repasting my GPU and CPU temps idle at nearly the same temps (before repasting I want to say there was about a 10C difference with my CPU idling around 60ish and GPU around 50ish), but my CPU temps fluctuate much quicker than my GPU temps (as expected).

I made damn sure to get tight, centered contact between my heatsink and CPU die, but as the GPU and CPU are slightly different heights I couldn't manage to get them both perfect even after some bending and tweaking of my heatsink assembly and heatpipes. (I tweaked, pasted, attached heatsink assembly, detached over and over again until I was happy with the results.) Despite the GPU die having a less-tight fit than the CPU, it still seems to be doing just fine (there are both pros and cons to this really).

I have also installed thermal pad stacks all over the place to help sink additional heat to the base plate from various components. (I had good luck with reducing NVMe SSD temps this way). I think this also helps the CPU/GPU share heat between the two as well which is fine since the GPU runs cooler in these and the CPU runs hotter.

Does anyone know how to get around the 10-20 minute fan cooldown timer yet aside from brute-forcing with the Dell fan utility I mentioned earlier? If I heat my system up enough to spin up the fans to their 2nd stage at around 5000 RPMs, they continue to run around 5000RPMs for about 10-20 minutes even after the load has long since gone away and the temps are back down...

Anyways, off to do some more homework. I would like to hear some of your idle temps / differentials if you got em for me.

 

Sadly even with the fan tool you can just set them at 2-3 fixed values, including just max fans. No way to make the laptop more quiet.

 

Luckily my repaste reduced my desktop activities fan speeds down a stage, they were hanging out in the 5000 RPM range full time which was annoying. The 3000 RPM range is much more tolerable and not nearly as loud. Still though, if I do anything that heats up the CPU for a brief moment too long, it will spin up the fans to 5000 RPMs and leave them there for the next 10-20 minutes regardless.

 

I had some time to run some more tests after getting home from work today and the bottom line is, I can't seem to push my GPU over about 81C and my CPU over 89C even while running a 1080p, 4k, and 1600 x 900 set of monitors along with both Kombustor's Furry Donut in 4k and Prime 95 running 8 threads of small FFTs at the same time. This is with a -146.5mv undervolt which I have found to be a 99.99% stable UV for my machine. (Although if I am not stressing it to the absolute max with unreasonable synthetic loads, it will run 98% stable at even lower undervolts for average office, school, and lighter gaming use cases.)

At this point, my only limits are power limits which sadly I have no power to get around, short of a GPU shunt mod and/or hacked and modded BIOS, etc.

Now I am itching to buy a stock backup heatsink assembly and some heat pipes and solder to play around with modding my original heatsink assembly at this point... I'm sure I could squeeze more thermal performance out of this if I tried (and have fun along the way), but there is really no point since I am up against power limits. If I can afford it soon, I hope to grab some Fujipoly thermal pads and I may take another whack at sanding, polishing, and fine tuning the fit between the contact plates and the various chips and VRs around the CPU/GPU etc.

Anyways, I grabbed some screenshots of my stats.

 

You wouldn't happen to still have that cable?

 

Hey guys - a bit of a long shot...

Did anyone archive the old BIOS recovery files (BIOS_IMG.rcv) for this laptop? Dell support pages only go back to v1.10 (with .rcv recovery option), but I'm looking for the pre-meltdown/spectre BIOS. The older ones are only available in .exe format, and trying to downgrade with those throws the 'Unsupported Downgrade' option.

TIA

edit: Disregard - it appears you can simply rename the .exe file to BIOS_IMG.rcv and it works.

Now back at 1.2!
