Ok, now I think I am getting confused. Can someone ELI5 g-sync, v-sync, and fast-sync?

 

Gsync is where your display refresh rate syncs constantly with your fps. For instance if the game is running at 43fps, the monitor will refresh at 43hz. This is the best solution to screen tearing because it reduces microstutter and doesn't introduce input lag. Vsync is the normal method. It syncs your fps to your refresh rate. Typically this is 60fps for 60hz displays and if it drops below 60fps it will usually lock at 30fps, not somewhere in between unless triple buffering is used which gives even more latency. It introduces input lag among other things. Fast sync is like vsync but your fps is uncapped. It has less input lag than vsync but is only good if your fps is around double your screens refresh rate. So if you are getting 120fps in a game and have a 60fps monitor fast sync is better than vsync. If you are around say 90fps then it's best to stick with vsync which would lock it down to 60 fps. If you have gsync just use that. Running games at 120fps just to use fast sync makes little sense if you have gsync. You are still only seeing 60 frames each second. Though higher fps may make it seem slightly smoother. This is all assuming a 60hz display btw. But the idea is the same across all. Fast sync is typically for if you don't have gsync and can get very high fps. Vsync is the worst but most practical.

Right, ok. I thought that g-sync was pretty much everything I needed. Except we are having issues with g-sync on this laptop, right? At least with the new nVidia drivers. Does it work fine with the older drivers?

 

There's hundreds of posts in the NVidia forum and a handful in Reddit indicating it's a problem with NVidia drivers and not this laptop. The only problem with the laptop is that G-Sync operates under the monitors refresh rate this laptop only runs at 60Hz. If the GPU delivers frame rates above 100FPS in most titles, it means you're paying for a lot of horsepower that isn't usable if you want to enjoy G-Sync full-time. That was kind of the argument I was making in my video.

 

I think the G-Sync would work if you have a lower framerate so something like 4K display which would benefit from G-Sync. A gpu nowadays can exceed the performance for a 1080p display which wouldn't benefit G-Sync

 

Also, games like CSGO won't benefit from 60-fps-gameplay, the standard there is 100+ minimum. I play that a lot, BTW. Anyway, maybe I'll be able to OC the panel easier since it's a TN one. Not a big deal for me going for an IPS g-sync

 

Do not buy that non-G-Sync TN panel ever. Or maybe you wanna replace it to another IPS non-gsync panel. There is only this panel on P6xx in China, we know how bad it is. You will surely notice that.

Edit: The panel in China is a non-g-sync 45% IPS screen, very bad. I don't know how bad this TN is.

 

I vaguely remember someone saying that the P670RS panel is 75hz refresh rate. Is that right?

 

They say it is and can be OC to 100Hz

 

I would LOVE it if Nvidia was responsible for the screen lag. Surely that would mean a fix is around the corner....

 

Reflexnotebook in Canada doesn't have a 17.3" 4K option for the P670 with the GTX1070. Is it possible to install one myself? If so, what part number,etc?

 

I think none of the resellers have that option at the moment. It would be nice though since a 4K display is better for G-Sync than the standard 1080.

 

So what's the deal with the monitor issue that I've read about? @Equatis had a pretty good review, owning the same model as what I'm getting, and it looked fine on his.

 

It is possible. This is the screen: http://www.panelook.com/LTN156FL02-L01_Samsung_15.6_LCM_overview_23360.html

I would probably recommend just getting it from someone who ships to Canada though or something. LPC Digital seems to have specific Canadian warranty.

Hey so guys why isn't this the official owners lounge now? Can we fix that?

Also anyone know how to get the exact SABRE DAC chip model? I wanna know to compare with my actual SABRE DAC.

 

the light bleed? It is a issue since the display is up against the plastic which makes it "bleed" a little kind of like pressing on the screen and holding it with a bit force. The screen would show this circle of light color around it which makes it noticeable with a black background.

 

I said it incorrectly, my bad.
I meant an external monitor. People were complaining about it or something other, but his looked fine.

 

I plan to connect the laptop with external monitor that has 144hz refresh rate, will it be capped at 60hz like internal?
Sorry can you also brief the problem with NVidia drivers as well? I have not been following up. Thanks!

 

Who is an admin that can change this to an Official page?

 

@Charles P. Jefferies ?

He's lead, idk if there is like a Sager/Clevo one.

 

Plugging in an external screen causes a single CPU core to jump to 100% use, and stay there until you unplug and restart. No fix as of yet

 

It's Official now.

Thank you! I was wondering the same thing too since I know there is a lot of people who owns these models and it is weird being unofficial...

 

So I was still testing my P650RP6 Gsync. I can say it's working on the latest Nvidia 372.90 driver. How? My test "game" is Unigine Valley Benchmark.
Gsync On, Vsync Off = screen tearing ONLY in around 2 inches at the bottom of monitor (consistent with the Nvidia forum @gooface posted a while back) as long as fps < 60, but all monitor tearing @ > 60 fps
Gsync Off, Vsync On = Stuttering as fps jumps from 60 and 30 (as Vsync normally works)
Gsync On, Vsync On = Smooth! Fps capped 60. Noticed no stuttering and input lag

 

So the tearing at the bottom is "supposed to be like that", or in other words one should expect it?!*

* no sarcams intended - just asking.

 

I thought that is the one of the way to get G-Sync to work?

 

I know it's weird until I saw it myself. That's more or less the same some people noticed. That is also maybe the reason why they named the forum "Nvidia Gsync not working 100%" because it was only like 95% of the screen.

 

That's what I'm trying to say. Because most of the posts here says Gsync is broken.

 

I run the 1.05.01TR1 (Beware there is a a seperate Version for the 15" with 1060 and the 15" and 17" models with 1070) Bios from XMG/mysn ( https://www.mysn.de/secure/userarea/download.asp) on my machine.

I do not know if I had this issues before, as I did not test it, but all I can say is, that I did not yet expereience any additional CPU usage when pluging into an external monitor via "mini dpi" be it on hybrid or descrete. Perhaps this will help?!

Thanks and sad to hear that We can only wait for bios update from Sager? No work around at this point?

 

Well my laptop has been dispatched, got to wait till monday for it to arrive. Just wanted to say thanks to everyone for all the information on this page, it has proved invaluable!

 

Someone above has posted that this issue does not appear in hybrid mode. But since the external monitor is always connected to the dGPU directly it should not be affected by hybrid mode being on/off. So this may be a workaround. But I don't know if anyone has confirmed that it works.

 

Has anyone taken a closer look at the thermal pads as well as paste on this model? I have read about other models in the past where pads were installed that were either too thick or too thin and have meant that the heatsink was not flat on the processor/gpu. Im wondering if i should invest in some pads to replace what comes with the laptop.
Thanks in advance!

 

The cooling system in general looks all pretty solid and well done imho. I admit that I´d like to have Kryonau instead of MX2 but the rest seems to be really o.k.

I`d like to see a video of a disassembly. As the cooling solution seems to be far more complicated and interlinked than inmy last notebook. The heatpipes appear to be linked with the fans quite firmly...

Without a littel help from my/some kind friends I will not venture to repaste on my own.

Best regards

phila

 

Speaking of cooling, do you guys use a cooling pad? I've heard mixed things about them. I'm ordered the P670 and am now wondering if a cooling pad may be a good idea. Any recommendations?

 

Hey. Yes you'll have zero issues with external and you'll be limited to external refresh rate, not internal display. Just make sure you get a display port cable if you're going to utilize G-Sync.

The problem with drivers affects G-Sync users using FPS limiting software. It's the better choice to enjoy G-Sync without added input lag, but apparently a couple drivers ago it got messed up. This guy I'm going to link you to did a great job of capturing the problem.

Users I've talked to with 8153 and similar variants have backlight bleed. Some are acceptable, others have sent them back for RMA or return.

There's several guys I've been chatting with that opted for 4K panel that are going to let me know if there's any difference in quality.

 

Hmm. I did that last night and it shut down no problem. I'm running stock drivers from the earliest models (had mine for about a month now.)

 

I'll be testing this over the weekend. Fingers crossed.

 

I do and, though I didn't measure temps, the fans seem to run less using it.
I bought this one:

I'm planning to order P650RS today from HID, any last minute advice? 1080p, 6820HK, 16GB

 

I wanna know how the 1070 really will handle 4k. 1080p is just not enough screen real estate for me, but 4k worries me about gaming and scaling. One of the two "3k" resolutions (1440p or 3200x1800) really feels like it would be a better fit, yet nobody is willing to sell monitors in these ranges.

HID sounds nice too, but man, their base price is just a lot higher, there's no prema yet?!, and their peripheral prices are like 30-50% above market.
I've got a budget and an itch burning a hole in my pocket, but it's seeming like waiting on a 10 series laptop for a month or holiday season may be the way to go : (

 

Yeah I'm also worried about 4k with gaming so I'm just going with 1080p to avoid potential blurry downsample

 

4k is 4:1 so 1080p downsample will look native! So if you want 4k panel for space but want to game at 1080 you wont have blurryness.

Did you get 4k? I've seen mixed feedback from people who game in 1080 on a 4k screen but don't remember anyone in this thread mentioning either way

 

Did you see this YouTube review yet?

 

Uhh it is out of stock at the moment someone on here said they are still waiting for shipments of new ones! You might be waiting for awhile before you can get one.

 

Yeah I got interrupted last time but just finished it. Sounds like 1440p would be the perfect resolution, any chance it will be an option from resellers or aftermarket?

 

That's what I've been asking and trying to find. Panelook doesn't show any 1440p panels in the 15" range, and this is all I found http://www.panelook.com/LQ156Z1JW03_SHARP_15.6_LCM_overview_21689.html, and I'm not yet knowledgeable enough to know where else to look or what specs to look for to make sure a panel would match.

Since my laptop is just that, nearly always on my LAP, the 15" form factor feels like a better fit than the giant 17". I'm almost ready to start considering 17" though for the sake of the right panel.

PS 2880x1620 just occurred to me and seems like a perfect sweet spot? But only 60hz? http://www.panelook.com/VVX16T020G00_Panasonic_15.5_LCM_overview_22014.html (wrong size?)

 

17.3 is not all that bigger than 15.6...just barely. Especially these! Panel quality is definitely better for the P670 and 17.3 after market.

I decided to reorder my P650RS through HID. I opted for the 4K panel and 6820HK CPU. I was getting a little worried about doing my own liquid metal paste job and I wanted color calibration for the panel. That together with the prema BIOS I felt justified the difference in cost. I also kind of felt this laptop might fair better with a dedicated builder. Normally I prefer factory support and my somewhat cheaper version of this order from LPC digital include a 1T SSD which I traded in for a 500gb EVO.

You should read @ Galm17's notes on the 4K panel. It sounds really nice and the 1070 can drive it for most games (and you can easily switch resolution to FHD when it doesn't since it's exactly 1/4 UHD).
