LENOVO THINKPAD P50 15.6" INTEL XEON E3 1505M 2.8GHZ / 8GB / 1.95TB

Q.L

17.12.2016

Hello. I noticed that P50 uses LP156WF6-SPK1 in this article, and You says that it is PWM-free. But I find some reviews of other models(such as Y700, X220, etc.) which use the same panel but they have low frequency backlight. So, If I want to replace the panel for my P50(using a PWM-220Hz panel, 1080P, NV156FHM-N42), will I get a PWM-free monitor by changing the panel? Which one control the backlight, circuits on the motherboard or the panel itself?

Sorry for such late writing, but in the article I saw it was written than there was no problem installing the GeForce driver. How did you do that? Any special procedure or tools for that? I might need that for some games, that's why I'm asking :)

801:1 806 Thanks for the review. It confirms Lenovo is cheating on customers by such medicore display component in premium price workstation (again). There is a small inconsistence in contrast ratio value. First you state "The contrast ratio of (black value: 0.31 cd/m²) cannot meet the advertised value, either." but the display section values shows - Contrast: :1

It says that the RAM is single channel in the review. I was wondering if that means the computer supports dual channel RAM but only has one stick or that it does not support dual channel. Mine is coming with 1x16GB stick. Can I get another 16GB of the same type and upgrade for dual channel capability? Any help is much appreciated

I hope this information helps.

I am quite curious about if the P50/P70 can take advantage of DDR4-2400 memory. I read that some Haswell thinkpad can have DDR3 memroy running at 2133, although intel ark says only 1600. I am thinking if similar thing happens on P50/P70 and skylake.

Q1: Does anyone have experience with the FHD touch model of this laptop? Is the LCD and the cover glass laminated like the Dell XPS 15, or is there a very noticeable air gap that results in double reflections like the Asus Zenbook Pro? Q2: During basic browsing, like reading this review and you open a link to another article, does the fan spin up then spin down again quickly? Eg: I find on my Dell M4600 (2011) workstation the fan spins up 50% when I open another page, and right after it finishes loading it turns the fan off immediately. This erratic fan on/off behavior when just basic browsing is annoying and I'd prefer to just have it be silent, or constant low noise. Thanks in advance to whoever can answer any of my questions. This is the top contender to replace my Dell M4600. Hoping to avoid annoying fan behavior in the future as this was one thing not mentioned despite NBC's review saying it the M4600 cooling system is a success and it silent and cool.

Hi! Very good review. I'm waiting for this since October from last year. I own a ThinkPad W520, very happy with it except for his cooling system, one fan can't handling the CPU + GPU at same time, so this is a problem for me. I'm a Aerospace Engineer student and I constantly run particle simulations, renders and other CPU + GPU related works. So the question here is very clear. I see that the P50 don't have any problems in the stress test for handling both CPU + GPU at the same time, so this is very nice for a workstation, in the other hand I'm worried about Turbo Boost. In the past weeks I read that Skylake has problems when it stress it, for example in Prime95, so maybe the Turbo Boost problems in your unit has some type of patch in BIOS form from Lenovo for avoid Skylake problems? http://www.extremetech.com/computing/220953-skylake-bug-causes-intel-chips-to-freeze-in-complex-workloads My only concerning about buying or not the P50 is the Skylake bug, that can be an important problem for me and for people that need stress the CPU. And I'm interested in the question from @Adamto, My idea is plug a Desktop Quadro via Thunderbolt 3 with an EGPU Case like the Razer Blade Stealth, but it is very important to know the controller, if the controller can handle 40Gbps there is no problem with port, but if it's only 20Gbps could be a problem with external graphics. Thanks! : )
