Lenovo Legion Y740 17" 15"

Hey Kalen,

thank you for your contribution to zoneykid and my "problem" with those gaming laptops.

You really saved my day Kalen. So if you say you can do some low performance stuff on this laptop and the fans are totally off it seems to be possible.
I don't know why many other owners say "yes the fans are quiet but always on".

You have the 15 inch model, right? Did you do the hotkey trick which zoneykid recommend?
Is optimus enabled at your laptop? Which BIOS version do you have?

Finally after 7 weeks of waiting my model will arrive at the end of next week.

Nice weekend to you guys.

Where's the info on the panel?

 

I do have the 15 inch 2060 model (ended up returning the 2070 Max-Q version because they gave me a better deal on the 2060 one). This is with balanced mode selected but not in Optimus; G-Sync enabled.
Hope you enjoy your laptop! I know I still am; It really is fantastic.

Hi guys!

I am joining the Legion family pretty soon.
Ordered the 2070MQ 15" for $1350 (6% sales tax incl.).

Is the 2070MQ really slow compared to the 2060? Apart from gamerdad.ca, I have seen that the 2070MQ mostly beats the 2060 (both in a Y740). Is that really the case?
I went with the 2070 because the price diff. between the two barely $30 for me with all the discounts.

 

I think with future driver optimization you'll see better results than what I had; it was early in the RTX lifecycle. The additional CUDA cores and 256 bandwidth should offset the lower frequency clocks. Great price for what you got for sure!

Looks like Y740 is on sale again. Also, @B0B is famous now, the link to your video is now on stickied Wiki post related to this model on Slickdeals ;-)
https://slickdeals.net/f/13044589-lenovo-legion-y740-2070-max-q-1385-99

2070 Max-q can be significantly faster than 2060 when it comes to min fps. You can see this in videos from OWNorDisown where he tested Dell models with same exact hardware, one with 2060 and the other with 2070 Max-q.

 

Shame its only about seventy bucks difference from my purchase.

Couple hundred and I'd probably call them on price difference

 

I dont know whether its because I have the 17 inch version, or because of the 2080 max-q, but my Y740 fans are always on. Although there would be thermal headroom to turn them off in idle (writing this, i get >40*C CPU and GPU temperature.)
Just experienced the fans out completely while writing this, but when playing a youtube video, the fans started to kick in just a tiny bit.
So maybe very light webbrowsing might lead to completely silent fans.
Have fun with the laptop and feel free to share your experiences with the community

 

Hello Alex555,

thank you as well for your contribution.

Ok that's everything i wanted to hear since i started the research and digging for every little new information about that laptop.

Mine is currently in the arabian emirates. It seems it doesn't arrive here within the next week (in total it will be 8 weeks of waiting).

Yes to say thank you to every youtuber, reviewer and forum member i will write down a short review as well as soon as my unit arrives.

Have fun with yours as well and see you soon!

 

I’m old. Can you explain what this Wiki post thing is you’re talking about?

Edit: ahh it’s something on the actual SD site. Got it! I must have missed that and I think I posted in that thread too.

 

After testing around I can't tell if setting the fans to max just cools down the rest of the laptop enough for the fans to kick off or if it's actually doing some sort of reset for the fan controller.
I notice some nights I have to leave it running on max for a minute, then turn it off and things will settle down for the night.

In any case, it's solved my problem enough to where I'll probably only continue on getting the utility to work if I have some extra time to satisfy my curiosity.

One thing that's really bugged me is the lack of SD Card reader, would it have been that hard to put one in? Even a MicroSD reader would have worked fine.

Other small thing: I wish they put a USB-C port on the back, so if I have a monitor that does displayport over type c I can just have a single cable for data and display that doesn't stick out the side.

Also, I don't understand why the power plug symbol light only turns on when the power is plugged in. I don't need to know where the port is if it's already plugged in...

 

So what is a good carrying case for the fifteen inch. I've got a pack for distance but need a sleeve or something for just carrying from room to room. Power brick pocket would be a plus.

 

Wow. Shocked to find that my laptop was shipped on the 26th. Said 29th it be here but checking the tracking. Thursday is anticipated (2nd May).
Kinda excited. But should be disappointed no 9750H unless they wanna surprise me...which I doubt.

OwnorDisown did a livestream on gaming performance. He clocks the fifteen inch 2070 Max Q variant being almost on par with 2080 Max Q.

Pretty good this early with RTX drivers.

 

Yeah, mine arrived today, 14 days after ordered. Of course the other one I ordered March 15 doesn’t arrive until Thursday, but they’re different models so maybe it’s that.

 

I solved the back-light bleeding problem. (kind of)

When the lid is open, the lid is very slightly bowed. It seems like the actual hinges might not be perfectly aligned, or too close together, though if that is the case, it's imperceptible.

If I straighten out the lid, all the bleed magically disappears - bleeding along the bottom and in the top corner. At least in my case, it's definitely not because "that's just the way IPS screens are".

The bending is super subtle. It was only once I noticed it that I was unable not to see it.

If you've got back-light bleeding, check this out: while you've got the screen turned on and set to an all black background, reach around to the back of the lid and apply a gentle pressure at the center of the chrome bar (made up to look like part of the hinge) at the bottom of the lid. Watch the bleed vanish as you push the bottom center of the lid slightly toward the keyboard.

I got the 15". Ordered in march. I'm returning it. I don't trust the glue, hinges, or screen to hold up over time if it's under constant stress like that.

 

I’ve been telling people that forever. Oftentimes it’s the trim squeezing the panel that causes much of our BLB.

 

It's so frustrating. The machine seems perfect otherwise. All they had to do was spend 50 cents to reinforce the bottom of the lid.

 

What would be a good way to reinforce the panel if that'll be needed/

 

This testing in done on my Clevo, but the results might be interessting for you owners aswell since the ram is plug and play. Got my HyperX impact 2x8 2666cl15-ram yesterday. Experience so far: It enabled itself on auto to run at 2666cl15-15-15 without me having to do a thing. I tested it using Aida64. With 2133cl15 running at 2400cl14-16-16 I got 33700MB\s read and 61.5ns. Stock 2666cl15-17-17 gave me 34500MB\s and 65ns. I thought that was a bit slow so I checked with bios and I used to run tRFC at 270 with the 2400cl14-ram. It was set to 467 on auto with the 2666cl15-ram. I lowered it and got it down to 420 stable, 410 won`t boot. Read went to 36500MH\s and latency to 63ns. I have tried lowering other values, but system wont boot. Compared with my desktop running i5 8400 with 2666cl14-16-16 tRFC 350 1.35V the laptop-ram is significantly slower. Desktop does 38900MB\s read and has 58ns latency. Guess that extra 0,15V makes the difference. Will try some additional testing later Haven`t really looked at gamingperformance yet.

Has anyone here got Aida64 and are willing to do some testing? The i7 8750H will probably give larger gains to latency and beat my setup easily, but I think going from 2666cl19 to 2666cl15 will make a difference in several scenarios. The Kingston HYperX impact also has modules that does 2933cl17 and 3200cl20, all plug and play so they will adjust to your systems maximum supported speed

 

So, got my 15” in. Played with it a bit last night. It does stay nice and cool, fan noise is often silent or close to. At full it’s very bearable. One thing.... speakers aren’t great. They’re kind of breaking up a bit. I haven’t run the Dolby software or anything yet, just playing around with it. Seems like not distorting but slightly crackling. Anyone have issue like this?
I will have the 17” tomorrow or the day after to compare, just not sure if it’s an issue or working as intended. I do have the in home service if I need it, so I’m not concerned, just want to know if it’s an issue or just the way it is. They are perfectly hearable over fans, so that’s not a problem.

 

When they finally announce and offer the 500nits screen option, how much will that add to the cost? Are we thinking +$100 or something in that range?

 

Another review of the Legion Y740 by HardwareCanucks. He pointed out the pros and cons on this machine and, made a minor remark on the Y750 - after that review, I think I'm going to wait for it in 2020.

 

I definitely am not adventurous enough to mess with the glue that holds the lid together, but if anyone is, i bet installing a pre-stressed metal dowel in the central portion of the the chrome bar would do it. It seems empty apart from some wires.

 

Well going through the throttle stop and checking things out with the analyzer. A problem seems that the laptop always wants to run at around 3.9 GHZ/ Is this normal?

 

What do you have your power slider set to?

 

Balanced as the Bob OF All Trades tutorial said not to mess with it.

Edit:Upon finishing the setup with throttlestop to start at login it looks to be behaving has supposed to.

Though now I've noticed that Hybrid mode is missing from the Vantage software.
So it just sucks the battery dry. Did they change something?

 

This one:

A pretty good one. However, I see that the GPU core clock is pretty high (1700Mhz or more even).
The 2070MQ has a max of 1305Mhz according to Notebookcheck
The 2070 Laptop has a max freq of 1440Mhz with boost
The 2070 Deskop has a max freq of 1620Mhz with boost

So, is the 2070 MQ running faster than the Desktop version in the above video?

 

Likewise, I think i'm going to hold off another year for the 750, since it seems like they are going to fix a lot of issues with that newer model.

 

Your talking at least 150-200 bucks for this

He does, and this is with the 15 inch, it's still kinda of a wash to wait.

It's kinda of a wash to wait.

 

There's no "max frequency." There's a boost frequency that Nvidia guarantees. My laptop 2070 I had before I returned it got to 1800-1950Mhz. My desktop got to 2000Mhz.

In the comments, he mentions that his 2070 MQ was a 90W variant but it was reaching 97W. It seems 90W variant = whatever-the-hell-the-cooler-can-manage.

 

The hurting part is the wait. But i just came to terms with a list of grounding of why i will wait: it is said to be a visual overhaul, a redesigned well-built-quality chassis (hopefully solid frame and lighter), integrating the Thinkpad keyboard, better and larger mousepad, a higher nit and faster screen (hopefully higher refresh rate, optional 4K, and no bleed), front-faced speakers (maybe bring back JBL), additional ports (hoping for more thunderbolt 3/usb-c). I know im hoping alot in the Y750, but i think Lenovo listens to their customers and learned from the Y740 to implement new features and make some better improvements that can impact a phenomenal gaming machine.

 

So, got my 15” 2070 and playing around with it. It was getting up around 91 in throttlestop stress test. I just undervolted it to -120mv and the gpu to -50 to play it safe. Running diablo 3, it’s the first game I downloaded just for kicks, downloading anthem now.... playing diablo 3 the gpu was up to 65 Celsius and the cpu was topped out at 75 Celsius. About 145 FPS. Nice and cool! Not sure how intensive diablo 3 is. Also the fans are super quiet! On idle and browsing or streaming I don’t hear them at all, could hardly tell they were running, and playing diablo 3 the noise was extremely minimal. Pretty damn good!

 

Also, that’s actually playing on my lap, wearing a robe, with no cooling pad or anything.

 

Agreed. Maybe it’s just me, but so far I can’t find a single laptop that’s well balanced. Most have crazy thermal issues. And others are just ridiculously expensive. The Y740 hits the sweet spot, but I think it just needs another year of refinement.

I can wait and I think anyone who can wait, it might be worthwhile. Not just for Lenovo but for even other laptops that may improve on cooling and optimization. If you can’t wait then I think this is definitely one of if not the best laptop of this cycle.

 

Can't say enough for how great this forum has been for all my Lenovo enthusiasms and go-to place for advice.

Are there any other great forums out there online that cover Lenovo gaming laptops or the y740 that you would recommend to check every so often as another great resource?

 

you might as well add a 10nm cpu to that list as well, along with grizzly kryonaut, a pantone callibrated screen, a 8k webcam, an amp, a mechanical keyboard with cherry switches, a slide out secondary panel, some hanging dice and maybe some french toast.

emphasis on other laptops...apparently this thing has to be an icebox.

 

Has anyone else heard of Thermal Grizzly Carbonaut gpu/cpu pads? This video was pretty interesting. Might give it a try in the future when I notice my temps start to increase overtime due to the thermal paste breaking down over time. Would love to hear y'all's thoughts on it as well.

 

Yes, there has been a few threads about it. This could certainly be better than any thermal paste since it will not break or pump out over time, however it is still not available for sale here.

 

Bad for some laptops. It is incredibly sensitive to mounting pressure. Having unequal mounting pressure can cause some core delta values that are extremely high. How well it performs can greatly vary from laptop to laptop

 

Only bad for defective laptops ;-) If you have laptop with uneven heatsink surface or uneven pressure caused by improperly mounted heatsink - it's a defect which should be fixed under warranty. If you don't have defective laptop - this should work well.

 

It depends. Some design are inheritly bad for use with pads.

 

Maybe, but this doesn't apply to Y740. I believe BOB of All Trades did a video where he used Kryonaut and there was no large difference between it and thicker stock paste. This shows there should be a pretty good contact between heatsink and CPU and GPU.

Here's the video:

 

Has anyone been having difficulty with the Killer Wireless software or card. My network connection fluctuates between about half power to no internet at all.

Also some have been speculating this is the thermal paste that Lenovo uses.
https://kingpincooling.com/products/kpx-high-preformance-thermal-compound-3g

its also very dense and has to be softened to be applied.

 

If your connection strenght fluctuates so much - I would first check for driver updates for the card, then I'd make sure that the antenna connectors are connected firmly to the sockets on the card. Sometimes poor physical connection can cause large signal fluctuation.

 

How does one get updates for that kinda card?

 

If it is a Killer Wireless card - you can check their official site for updates.
https://support.killernetworking.com/software/

 

Personally I’m not a fan of killer cards and would much prefer intel wireless cards. Killer cards seem to run into more problems for whatever reason.

 

Newer ones are rebranded intel cards, can’t you use intel drivers?

 

Agreed. The only laptop I would say is superior is the Clevo PB51EF-GPB51EF-G due it having the 2070 Max P as opposed to the Max Q in the 15" form factor. That alongside more ports, an extra M.2 slot, and a larger battery. It is a tad bit thicker and heavier however.
