Dell 17r N7720 SE - user review

of course, i always compared 650m and 750m both with GDDR5... you can reach 750m level with slight OC on 650m GDDR5.
750m is basically rebranded 660m.

I would wait for 760m, if i would like to replace my 7720se.

 

you can "overclock" a old Ford to a super fast Porsche (but it runs hot like hell and dont stay in a perfect condition long time.....

the GT750M GDDR5 is about 20-25% faster.......im not saying its a GTX TITAN...........but its a very nice card, for medium end laptops.

ps.....20-25% extra power in BF3 (or some other high shader game) is welcome

 

Wrong analogy – it’s the same exact core, GK107. Of course it might be easier to overclock thanks to higher default clocks (no need to mess with the +135MHz limit) and the overclocking potential can be different for every single chip, even of the same branding and default values. Either way it’d be as pointless as upgrading from GT 650M to GTX660M without changing anything else. Not to mention that if you want a laptop for gaming then you should get a different model.

Plz advice

 

On my dell 17r SE 1TB hard drive, accordingly to hd tune pro, have a Calibration Retry Count of 2 and it is a warning. Is it very bad? Should I call dell to replace my hdd?

It appears that Dell's engineers finally sorted GPU boost issue... by disabling it completely in BIOS A13. Updated to that a few weeks ago and never done any tests at the time, but today I noticed that whatever trick I tried (99% CPU, unplugging power adapter, reinstalling drivers etc), the core frequency stayed at 745 MHz. Reverting back to A12 sorted the issue: the boost works fine. Additionally, with the newest nVidia drivers (314.22) it's not necessary to cripple the CPU with 99% setting as GPU does not seem to be affected by CPU boost. GPU remains fully overclockable and will boost to 835 MHz when necessary. However, the issue with unplugging power adapter remains unsolved.

 

Thanks for the update. I've just learned to live with it, to be honest, I don't expect we'll see a fix from DELL this far down the product cycle... I'm still on A03, have never seen a reason to update. Apart from a fancier graphic at system startup, what is actually better in A13 compared to A03?

 

Iam using Bios A13 and GPU boost is still there (issues included) .. But for example Lenovo disabled CPU&GPU boost on some of their products...

 

This appears more messed up than I thought. After reboot, the GPU core got stuck at 745 MHz again. Removed 314.22 driver in order to go back to Dell's 307.07. Another reboot and 650m disappeared from the system completely. Instead, an unknown device (Xeon CPU?) popped up on system devices list. Removed that, reinstalled the drivers and at the moment everything seems to be functioning fine, but this is seriously worrying. If your system is stable, don't "upgrade" to newer BIOSes. Unless you like to troubleshoot...

 

try take out one disk if you´re using two and re-roll to A11 BIOS.. Disappearing GPU is known problem (Dell is working on this fix).

 

Hi guys, just saying hello.
I've ordered an Inspiron 17 R SE 7720 yesterday as an upgrade from my Dell XPS L501x which has been a great laptop but I have decided to move on as it is nearly 3 years old now.
Looks like this is the main Inspiron 7720 thread so I will stick around for info and share my own experiences when the laptop arrives.

 

Is the 17R worth it?
Dont want to spend more for SE.

 

Has anyone experienced with the DC power jack/port becoming less responsive over use? I've noticed I've had to re-adjust my power cord with the 7720 a few times to get it to charge.

 

Can anyone here help out to tell if there is possibly any way to enable single finger scrolling on the ALPS touchpad on 7720 ?

Have you tried unticking Two Finger Scrolling?

 

The scrolling stops entirely then

 

Hi Guys
greetings to u all from India!
this is my first post so please be kind to me - as i am not as technical as you guys are as most of the discussion is in regards to CPU/GPU overclocking of both etc for diff. games
I just purchased this laptop however mine came with i5-3210 CPU with optimus enabled

info here : Dell Inspiron 17R Turbo Laptop - Performance Laptops from Dell

Only exception in my laptop being the FULL HD anti-glare [non-3D] screen the laptop came with - rest all the same as given in the link.

So far so good - i have now started testing it's features

I already have the Asus RoG 3D version - G74sx - 3d version so i purchased this for my DTR needs [watching movies,video encoding,etc]
I have uninstalled win 8 and clean installed win 7 hp service pack 1 with all drivers installed ok

I have Sony HMZ-t2 which i want to use with this [inspiron 17r] for watching blu-ray 3D iso from my collection using the virtual clone drive mounting.

To my shock - HMZ-T2 sony personal 3d viewer is identified as 2D monitor - not the 3D one ! - dunno if it's the 650m drivers [driver ver.314.22] or optimus but i cannot get the 3d iso to be played back in 3d using the TMT v5

Has anybody with the same model as i have tried watching 3d movies from this to a 3dTV ?

any help please!

 

According to NVIDIA not all GT 650M equipped laptops support 3D TV Play. Link HERE

 

thanks for the reply so disappointing !

Now my next query - How do i watch blu-ray 3D iso on this laptop and output to 3d TV - any softwares etc ?

any suggestions please ?

 

You are asking the same question mate.

 

could be the optimus, since optimus and 3d do not mix.
Try to have the laptop runing the nvidia card all the time or try to run on nvidia the app you use to see 3d movies.

 

Wow, I hope you guys on the bleeding edge get a fix soon! I think I'll be sticking to A03 for some time to come. I gotta say that after the initial week or two of getting everything installed and settled in, my 7720 has been rock stable since. Then again the only changes to the system I do are Windows patches and gpu drivers... if it ain't broke and all that...

 

Collecting my laptop from UPS depot today, as there was nobody to sign for it. Can't wait! :

 

congrats..............now you just have to do a clean install of windows..........and off you go

(you dont have to do it....but it makes your PC faster & better)

 

I too am having issues watching 3d youtube because the IR transmitter just wont turn on and i cant find a setting to turn it on.

I don't see why i cant watch 3d movies or 3d youtube when i can play games in 3d.

There are instructions on other forums to turn on the setting from the nvidia control but i don't have this setting.

Do i need nvidia 3DTV play to watch 3d movies/youtube on my laptop? My model came with the vision 2 3d glasses and 120hz screen.

 

If anyone else is having this issue i solved it by updating ms silverlight.

 

SSD should sort that out nicely. Getting one soonish. Looking at Crucial M500 240GB

 

What is the max memory speed on the Inspiron 17R SE?
Can it handle 1866 memory?
I got the i5-3230 processor.

Think I found the answer on intel page. Max speed is 1600Mhz for i5-3230 and i7-3630

 

every Intel CPU with the FCPGA988 socket fits.............so in your mind....the 3230 fits

just go with the 1600mhz speed....trying higher speed often gives conflict

 

Bios A14 has been released. GPU boost issue wasn´t solved in this release....

 

i dont know about the bug, but it is definitely better than a13. i had problems with low gpu usage (due to heat i think) and turbo boost (didn´t work at all). now it seems to be fine. now they have to improve the fan control... .

 

Hopefully they have not limited/downclocked the GPU to prevent overheating.

 

Just wondering, can anyone tell me what their HDD temps and Mobo temps are when gaming (with something like HWmonitor?)

I noticed my mobo temperatures (TZ00 and TZ01) get to 80C, so I'm wondering if that's normal - it seems pretty high to me

Also my HDD is getting to 57C after heavy gaming, does anyone else see these kind of temperatures?

 

no dell didn´t. it´s actually quite the opposite. with a13 tubo boost stopped working and now it´s working again.

 

A14 what are the changes ? Anything worth updating for from A03 ?

 

That's some good news then. Time for an update!

 

Anyone else having update trouble with win 8?

Still getting error 216, just as with A13.

 

another reason why using windows 7 SP.1. :thumbsup:

i waiting for windows 9 (a shorter version of windows 8 but without Metro and not optimized for Touch screens)

-----------------------------

SHASHANK_BEST
............i would stay with A03.......its very good enough. (for me it works flawless)

 

My windows updates working fine.
I have done a clean install of Windows 8 Pro though.

Would not want to use 7 at home again. 8 is great once you get used to it and it is fast!

 

the new bios a14 is perfect. GPU in games goes up to 835, before on a13 i was autounderclocked 745, and even in idle fans are almost silent

 

YA a03 IS GOOD . bUT if A14 resolves GPU boost issue then it is worth it ?

 

well....i tell you this................im not going to jeopardy a new BIOS just because one guy tells you everything is heaven.

if all people confirm....then i might flash the BIOS

 

this bios is great well done before they improve its like drive in bmw with limit speed now is work great i think they need to improve more but for now is great

 

i dont beleive the reasult i see from fc3

 

what results ???

 

the speed is 835 mhz without reduce

 

if you want mod bios i can give you link work only 3610qm let you see hideen function

 

Please confirm on how a14 BIOS is actually ?

 

how much we wait for get this reasult why they dont make this work in the begining its just bios not space project my mod bios is even work alot better
