Dell Inspirion 7577

For everyone complaining about temps... Did you undervolt yet using Intel XTU or Throttle stop? -0.160V undervolt brought my temps down across the board by like 10C. My machine doesn't even sweat playing Overwatch on high settings.

 

One of many links that give ways of fixing slow explorer launch when clicked from taskbar:

https://windowsreport.com/file-explorer-slow-windows-10/

With enough/the right tweaks your explorer will act normally. (Mine does.)

 

Yes, I use intel xtu (but -0.150 leads to shutdown, so I do -0.130v). But it doesnt solve the issue with GPU temps. They got higher for some reason and I want to find out why.
By the way, turning off turboboost doesn't affect perfomance in majority of games, but it also decreases cpu temperature as well (no undervolt and with turboboost temps in pubg are 75 (gpu) and 90-95 (cpu); with undervolt and turned off turboboost it is 72 and 76)

 

Thanks for that link. I'll check it out.

After my last post late last night, I decided to check a setting in UEFI. After checking that setting, the system would never boot back into Windows. I couldn't even boot into safe mode. Kept getting the light blue SOD (something about a configuration problem).

In the end, I had to completely reinstall Windows. During that reinstall, I noticed that before installing the Windows updates, file explorer seemed to respond normally. But after the updates, the lag was there, but not quite as bad as I experienced yesterday. I'm not too sure about that nvida fix I posted either.

Yesterday I had a 5 second lag opening FE. Today. after the reinstall and updates, it's only 2 seconds. But I'll definitely check out that link. I don't use Cortana anyway.

 

With every laptop i've had there is massive delay (2 to 5 seconds) when you right click on desktop.

I've found Intel Graphics options and Graphics Properties there cause this delay.

You can try disable it and maybe it helps.

With Windows 10 Manager i removed all useless right click options (including said Intel ones) and now it blazingly fast opens any explorer window or right click.

 

My friends, I will be leaving this thread. You guys are more useful than any tech support assistant from dell or any other company ever.
I wish you all cloudless IPS panels and no themral throttling. I hope your mobos don't ranomly die but if they do that you at least get the same copy of the laptop, because I did not.
I'll probably be getting an HP Omen with an i5/1060 and a 120hz panel. The thing looks damn ugly and doesn't seem to have the best battery life but I do respect the internals espefiallt at this price point (I'll be paying 20€ more and getting a 120hz display, 1tb HDD in addition to the SSD and +8gb).
I'm not 100% sure tho as I might get an Alienware 13r3 with a gtx 1050ti for the better protability and battery life. Any advice on this would be appreciated but this is probably not the correct topic haha.
Anyhow I hope you all have a great expirce with the laptop!

Does anyone know what the fastest memory which that the 7577 sees and utilizes, DDR4 2133, 2400, or 2666?

Do laptops support Intel's XMP 2.0 memory overclocking, or is it strictly utilized on desktops?

I also noticed that Dell likes to ship their laptops w/either a single stick of 8 or 16 GB of memory, which means they are only running on only just one memory channel vs. the normal two, which can effect memory performance.

Thanks

 

https://ark.intel.com/products/97185/Intel-Core-i7-7700HQ-Processor-6M-Cache-up-to-3_80-GHz

The 7700HQ only officially supports up to 2400MHz RAM if you read its specs. There isn't too much more to be gained beyond 2400... The returns diminish quickly up to about 3200 where they nearly stop altogether iirc.

There's also a post here on the forums about how to manually overclock pretty much any Ram I believe but it's complicated and you can definitely screw it up if you don't know what you're doing.

 

The maximum DDR4 speed supported by the 7577 is 3100MHz (with decent timings for your own mem stick and CPU IMC). Best bet for 3100MHz is Crucial Ballistix 2666 OC'ed to 3100 or some extreme Samsung C/D-die 18nm one (extremely rare, pure unicorn) while still running 1.2V......
Our 7577 support XMP 2.0 too...
No support for mem voltage control, sad...
Im experimented with my Hynix stick (A-die, 21nm), once got 3100MHz @ 18-20-20, unstable. If there is an voltage control, then it would be stable...(need an extra +0.15V for it on my other laptop)
Currently running 2900MHz @ CL18

 

My XTU setting for my 7577 i7 7700HQ, stable for mine and able to cut almost 20 Celcius on serious load....
Processor/Cache Voltage offset -0.165mV
Processor/Cache IccMax 68A (idiotic Dell set it as 70A while Intel suggested max 68A, extra 2A did nothing than wasting heat)
Turbo time 128ms
Cache ratio 37x
iGP voltage offset -0.180mV
iGP IccMax 55A
FCLK/Ring clock 1GHz (extra PCIe speed, and idiotic Dell strikes again with their 800MHz value, against Intel value)
Disable Spread Spectrum for more stable overclock.....
HPET clocked at 24MHz, not idiotic 14.56MHz value....

 

Thanks everyone for the info.

 

Please explain how you managed to set all these settings in XTU?

 

I went and ordered, and just received, another 7577, but w/just the standard 1920 x 1080 Screen.

I originally got a 5577, but the picture quality on it, sadly, was really bad, so I returned it for a 7577.

I ordered the 7577 w/the UHD 3840 x 2160 IPS Anti-Glare LED-Backlit Display (4K). When I received it, and first turned it on, I immediately noticed right away the screen bleed in the upper corners on it, w/o looking for it. The over all picture quality was OK on the 4K, but when I went and looked at a 7577 at a local Best Buy store, w/just the standard 1920 x 1080 screen, it looked OK to me, and I wondered if it was really worth the extra money for the 4K screen. Of course this is a personal opinion on my part, and everyone else's opinion may vary, just like a speaker system sound varies from person to person.

Dissatisfied, I went and ordered, and just received, another 7577, but w/the standard 1920 x 1080 screen. When I first turned it on, I didn't immediately notice any screen bleed like I did on the 4K model. Does it have any, yes, but you have to look for it rather than it immediately sticking right out. Over all, the screen picture quality on the 1920 x 1080 it is just fine, for me.

Next I went and loaded up the CPU running BOINC/SETI on it, together w/HWMonitor. When I ran the 7577/4K Display model, not all the cores measured the same, w/as much as a 6C difference, which meant I had to disassemble the laptop and re-paste the CPU. With my new 7577/Standard Display model, all the cores measured about the same, w/in a reasonable margin of 1 C or so. So no need to re-paste the CPU.



NOTE: This 7577 came w/the RAID On in the BIOS vs being set to AHCI, while the other two laptops didn't. When I tried to switch it, it said that I may need to reload the OS. Is this true, will I need to re-install the OS? Thanks.





.

 

No you (switch to AHCI) can do it without reinstalling, try this:
https://triplescomputers.com/blog/u...ch-windows-10-from-raidide-to-ahci-operation/

 

Thanks

Update: It worked, thanks again.

 

It looks like the 7577 I just got, w/the standard 1920 x 1080 screen, is going to work out fine for me. There's very little Screen Bleed on it, and the picture quality is just fine for me.

I went and upgraded the SK Hynix 128 GB M.2 NVMe SSD it came with to a 250 GB Samsung 960 EVO. I made sure that the AHCI Setting was set in the BIOS. I went and used the Dell Recovery Tool w/o any problems to set it up.

Questions:

Any opinion(s) of the Killer 1535 WI Fi Card vs. the Intel 8265, which the 7577 comes with?

When it comes to memory, will the 7577 support DDR4 2400 beyond 16 GB, or would I have I have to go w/the 2133? My Alienware Aurora R5 supports DDR4 2400 up to 16 GB, but beyond that, it only supports 2133.

Finally, has anyone tried the Razer Core V2 Thunderbolt 3 external desktop graphics enclosure on the 7577?

Thanks Again.

Killer 1535 only better than Intel 8265 in some extreme case like 5GHz network with super duper Wifi router that support those proprietary techs found in Killer card. For the rest, Intel is better and got a Bluetooth feature built-in.
Memory, yes it will support 2400MHz stick. Maximum speed for our 7577 is 3100MHz....
I tried an Alienware Amplifier and its working....

 

Interesting. I did not have to do that bcdedit fix. I simply changed from RAID to AHCI when I first cranked up my 7577 and when it rebooted, it booted into safe mode automagically and just worked. I then inserted my bootable USB drive with Win 10 and did a clean install.

Initially I thought my 256GB m.2 drive was slow. It was much slower getting to the desktop than an older Toshiba laptop where I recently swapped out the HDD for a SATA SSD. But when I drilled down into event reporting and checked boot times as reported there, the 7577 was reported as faster than the old Toshiba that I thought was faster. Well, at least the old Tosh was 2x as fast getting to the desktop!

I'm not sure what the boot numbers being reported in the event viewer tell me if it varies considerably (and it does) from what my eyes see.

 

[QUOTE="spektykles, post: Maximum speed for our 7577 is 3100MHz....

3100 MHz?
Was it noticeable?
Does the 7577 utilize XMP?

How did you run an Alienware Amplifier on the 7577? It has a special connector on it which only the Alienware laptops have built in, vs w/the Razer Core V2, which uses Intel's Thunderbolt 3 connector, which the 7577 has.

 

My phone is being stupid.

 

Anyone know when the next generation Inspiron 7000 gaming laptops with 8th gen i5/7s will be released? Saw another thread that appears to have a pre-listing with 1050 Ti.

Was planning to buy 7577 with i7 and 1060, is it worth waiting?

 

For the lulz only and some memory and CPU intensive tasks....
7577 supports XMP 2.0, nearly all Dell laptops from 2012 support it (hell, my old Latitude E6330 still running dual 1866 XMP 1.3 stick)
IDK, I tried at an Dell showoff booth, they have like 2 amplifiers on the show and I asked to try them. They said yes. When I bring out my 7577, some of the reps couldnt quite get it. Luckily one did bring out an dongle for converting IDK WTF proprietary one to TB3 for me to test (not exactly an dongle but a small box, less than our ac brick and has multiple output beside TB3). I though the retail Amplifier would include that, and I doesnt have they money to buy one...sigh...

 

The new Dell 5587 is here with 8th gen Core, and look like our 7577 only need a board swap to become the 5587...sigh....

 

What did you use to set that? On HWiNFO I see System Agent Clock at 798 MHz. Is that the correct target?

 

For those who were having issues with lag spikes on right click and other actions, a Windows update today fixed the issue for me.

 

how to downgrade 7577 bios version from 1.4 to 1.2 (stock) ?

 

Hi guys.

I was reading a lot through this forum lately and decided to sign up. Yesterday i repasted my 7577, and while doing it i came across those shunt resistors and could not resist to modify them. I dont like the idea of putting Liquid metal on anything in my machine, so i soldered two R010 just on top of my notebook's shunts. Which in theory means, that their value is now 3,33 mOhm. This should increase the possible power consumption to 90w.

The reason why i wanted to bypass the TDP limit is simple: I love the machine but i hated those jumping frequencies betweein 1200-1700Mhz.
I ran a few benchmarks before and after modding the shunts. My grafics score in firestrike was 10,3k before i modified the resistors and is 12k (whats the desktops 1060's score) now with the default curve. The frequency stays steady at 1671 Mhz and there is no more power throttling. Since i did not do this for overclocking Issues i lock the curve at 1,5Ghz @0,8 volts. This is enough power for me at the moment.

Here a pics of the motherboard:




And here a screen shot after running valley:



According to HW, the GPU runs on average at ~70W and the peak was at 86W. (Stock curve)
I am not sure about the"ambient" sensor. I guess it stands for the VRM temperature, 80° isn't too high for it, is it?

Untill now all seems to work very well, but i have no long term tests yet, but will post here again if something goes wrong.

P.S.: Notebook: Dell 7577, i7, GTX 1060, 16GB RAM, NVME SSD

 

Top notch work. This needs a spot on my 7577 thread. Although I've never had any throttling issues while plugged in and combined with a -.160 V undervolt my machine stays very chill.

I've been getting to know Throttle Stop again and was recently trying to figure out if there is a way to bypass the 15W power limit when the laptop is unplugged. It throttles the CPU into the 1.4GHz range on 4 cores while under load when unplugged which is a bit disappointing... Not that I ever intend to game on battery really.

 

So my parents just bought this laptop for me 2 days ago, and i uninstalled mcafee and the likes, should i still do a fresh install? And do i need to switch my ssd to AHCI from RAID because it won't be detected during the setup?

 

I certainly would ... and did. When you change to AHCI, the laptop will boot into safe mode, then should boot normally afterwards. At least mine did. Create a bootable usb drive with the Win 10 ISO and use the f12 key to selectively boot to the usb drive and reinstall Win 10 clean. Delete all partitions on the destination drive (I installed to my 256GB m.2 drive). The Win 10 installation process will create all needed partitions. All drivers will d/l and install automatically once you finish the install. Just leave it connected to the 'net and it will do it in the background.

You can get later drivers from Intel and nVidia later if you desire. It was the most painless clean install I've seen.

 

I can still get the drivers from the dell website right? Do i need to place my ssd back into raid mode after? Or is ahci better for the laptop?

 

Honestly, I left mine set for AHCI. I see no need for RAID... and from what I've been able to research, there doesn't seem to be any performance advantage or performance hit either way, so I felt AHCI was simpler and easier to deal with going forward.

I created a bootable USB stick using Rufus. You can download the W10 ISO from multiple sources such as:
https://tb.rg-adguard.net/public.php

Rufus here:
https://rufus.akeo.ie/

Change RAID to AHCI (system config/SATA operations/SATA or RAID) and shutdown. Stick the bootable drive in the USB slot and start it up. Use F12 to boot from the USB drive. Then just follow the prompts. I typically don't create a MS account and I also delete all partitions on my destination drive (I used the m.2 256GB NVMe drive as my OS drive).

Windows will get the drivers it needs as you do the install so you don't need to download any drivers (I did because my history with older Dells was that I needed them... but it turns out that I didn't for the new 7577).

At some point you'll have to enter your connection info so it will connect and d/l the needed drivers automagically. You can later update to the latest drivers from Intel and nVidia if you desire. The drivers installed may not be the latest from the mfg but will be the latest on the Dell support site.

A few custom tweaks I made to the UEFI:
1) FASTBOOT set to minimal
2) POST set to 0
3) I disabled security/UEFI capsule firmware updates so I could control when updates from Dell occur
4) power management/primary battery charge config/change from adaptive to custom 60-65 (because I typically use the laptop plugged in. I chose this as I think it will help with battery life down the road).

At some point you may wish to update your BIOS too. But that should be pretty straightforward.

 

Okay, with newest 1.4.2 BIOS, and my 7577 mostly tuned how I want it using ThrottleStop (among other things), my best FireStrike score so far with a -0.160V undervolt and +205MHz (Core) / +550MHz (Mem) OC w/Afterburner was 9500 and had a graphics score of 11158. CPU stays between 3.5 - 3.8 GHz most of the time except during the CPU only physics test which maxes all CPU cores and yields only 3.4GHz for that section. Also max temp so far after several runs and adjustments has been 78*C with an ambient temp of 27.8C and stock paste.

 

Based on what I read on internet, dell inspiron gaming series will be changed to dell g series. That means, we wouldn't see another inspiron gaming series after inspiron 7577.
You can check dell g series on internet. They have announced it and some of the model will be available for pre-order later in this april 2018.

 

Anyone with stock Toshiba NVME 256GB drive? What write speeds do you have in CrystalDiskMark? I guess it is about 330-350MB/s.
I need you to make an experiment. Please, make a fresh Windows installation from clean image (not Dell). Do not connect to WiFi, do not install any drivers. Just make installation with no internet connection. And then test your drive in CrystalDiskMark.
If any of you can do this, please share your results here.

 

Hi @charlotte1776

Did you find the cable model? Have you been able to mount your 4k screen?

 

This particular issue has already been discussed in more detail some pages ago in this thread. You can try searching for my posts as well as custom90gt's posts as we were two of the people going back and forth discussing this stuff already.

 

Part number for Dell 7577 UHD cable is 8VWHF.

I have brand new spare Dell 7567 UHD cable XFWMX, I think connector should be compatible. I can send you by mail if you cover shipping. I am from europe.

 

The question is, does the 1080p model and 4k model 7577s both share the same connector and pinout on the motherboard ends?

 

I think all 7577 motherboards have 40 pin EDP connector.

Here is new Dell G7 Service manual - http://topics-cdn.dell.com/pdf/g-series-15-7588-laptop_service-manual_en-us.pdf
Basically the same 7577(besides 8th gen cpu) only with some cosmetic differences, they even use same motherboard pic for both service manuals

 

Where did you get that cable part number from? I wonder if the part numbers are the same for 1080p/4k mobos.

 

Sticker on cable itself.

 

I've been using this laptop and its pretty decent, just kinda bland. There was a weird issue with the system hanging momentarily and it was resolved by taking the second hard drive out.

I find the screen to be very dull, odd for an IPS display. I miss the OLED display I had the opportunity to use on the alienware 13 that came with a broken speaker ... lol at dell Quality...

 

Yeah, I have it. But I've already done a clean install and am well beyond that now, so I'm not inclined to start my setup again!

What are you looking for exactly? I ran CDM at some point after the clean install but don't know if I kept any screen shots or not.

In fact, that m.2 drive was an initial peeve of mine, thinking it was kinda slow. Or at least it appeared to me to be slow... in comparison to how long it took an older laptop to boot to the log in screen. But I later learned how to check the boot times in the event viewer and apparently my 7577 is much faster than the old Toshiba with a SATA HDD. But the eyeball/stopwatch method sure was convincing to me! (the old Tosh handily beats my 7577 to the log in screen by a factor of 2x or more). Shrug. But what do I know?

 

The thing is, if you test this drive on clean, bare bone Windows with no drivers (expect Windows' working minimum), it easly scores 1000MB/s write speed.

 

So i just did a windows fresh install on my laptop, and i've been using it for almost a week now. While browsing the thread, it looks like a lot of people are undervolting, should i try to undervolt mine? I've been using my laptop mostly for gaming and does anyone have a guide for undervolting? Planning to just copy since i don't know a lot about it.

 

Yes undervolt as much as you can and still be stable. It really tames the temperatures and keeps my fan OFF significantly more when doing light tasks. Your range of undervolt will likely be between -50mv and -160mv.

REVISION (all testing was done at 27.2C room temp with no fans or moving air) :
In case this helps: my 7700HQ shoots straight to 98*C nearly instantly when running Prime95 (first option) at stock voltages and peaks at as much as 60+ watts when running at full tilt but usually settles in on an 8 thread load at the 45W TDP due to thermal throttling. It throttles pretty quickly really.

However the equilibrium seems to be at about -110mV undervolt which brings the maxed out CPU to about 44.5 - 45.0 watts at 92C.

At -118mV the fully loaded power consumption was at 44.0 watts at 91C.

At -160mV the fully loaded power consumption was at 40 watts at 86C.

So all said, if you can get at least -110mV to -120mV out of your silicon you will pretty much never have to worry about overheating with real world loads.

 

Hi guys do Dell sell models of the 7577 with full 1060s or are they all Max Q? Was looking at the Dell site and it states 1060 if its max q that would be pretty misleading... Thanks!

 

They are all MQ. My 7577 scored a 9500 on FiresStrike (11k graphics).

 

I looked but didn't see any CDM screen shots of tests I ran. Can you post some of your examples?
