L702x Vs L502x

As from the specs what dell displayed on their site
on 1st feb
L702x has the following specification

The Dell Online Store: Build Your System

a full hd screen but with white led
and there is no b+rg led option
will this make a big difference between the two screens?

the question arises here is that which card L502x is going to have
as far as i suppose it will have nvidia GT 445m but not GT 555m

so which laptop to go for?
L702x is somewhat costly as
i suppose the graphics card is of 3gb and some of its higher base configurations
i hope that L502x will be cheaper
Does anyone knows whether new refreshed SB xps 15 L502x will be released with SB xps 17 3D L702x
or dell will maintain a difference of 1 month between launch dates of these two laptops?

 

Where does it state this? All I see is FHD+ (1080p).
Doesn't say WLED or B+RGLED anywhere

 

That link has been discussed & dissected many times on this forum.

It is a pre-launch copy of the planned 702x config launch which was pulled by Dell due to the Sandy Bridge processors being pulled. This is quite clear as it still allows you to configure the laptop using the Sandy Bridge CPUs WHICH ARE NO LONGER IN CIRCULATION. The page is only available via a direct link, is not obtainable via the main site and is not a current model offered by Dell.

If you attempt to order using it, you'll have your order deleted and/or modified automatically. It is also clear, given the way Dell changed the UK/Eur available specs for the 501x [pulling the i7 chip without warning] that Dell will change spec lists without notice & without a press release.

This means the link is a historical reference and totally unreliable.


[edit]

And yes - I've seen the news that they're shipping the Sandy Bridge units already made, however - that doesn't make that previous link any way legit. "Intel is resuming shipments of the Intel® 6 Series Chipset for use only in PC system configurations that are not impacted by the design issue."

If you've not noticed - most XPS 17 models have x2 HD caddies. With an optical drive, this means they are not eligible for the 1st gen Sandy Bridge chips with the error. The only way Dell could ship a XPS 17 with a 1st gen Sandy Bridge chip would be by shipping the x1 caddy chassis - and not offering more than 1 HD. This doesn't apply to the 502x so they, theoretically, could be shipped using the 1st gen "broken" Sandy Bridge chips.


If you want to see the actual planned 502x specs, there's a link around for it - a blog entry. A "best case" sceanario is that the 502x is actually launched earlier (late Feb / early April) than the 702x and will feature the Sandy Bridge chips [which the 702x will not, unless they move to the x1 HD caddy chassis].

 

Nope, the L702x could never utilise the faulty Sandy Bridge as the eSata uses one of the dodgy 3GB sata ports on th SB chip.

HDD , optical drive and eSata that's three, so unless they cut one it's a no go for sure.

I doubt there will be any 702 option for a few months yet.

 

Could you find that link? I would love to give it a look.

 

The speccs on the blog aren't very revealing. Since Dell never actually announced the 15 at CES, their main XPS thing being about the 17 and it's 3D. Anything about the 15 is just speculation and based off of the released info on the 17.

The blog post says it'll have SB processors, chicklet keyboard and most likely a rebadged slightly higher clocked GPU. So basically what anyone would have guessed from seeing what was announced about the 17.

 

Hmm, my reading was that the mobo could take a dedicated J chip/port to handle eSata - my thinking was that it might be cost effective to add this in, remove the 3 connection & offer with 1 HD (which - if you've not noticed, is the usual model for UK/Eur sales, 1 HD only - or at least the options are usually only available for x1 model (may have changed). Its only the USA + special deals that ship with x2, or even offer things like SSDs*)

However - I agree with you. The amount of retooling / nerfing / hassle to ship the 702x as planned probably means it'll be delayed, and just shipped when the 2nd gen SBs come in.


*This was accurate back in Jan when I was specc'ing up models.

 

If you check the XPS drivers you can see that the eSata port is controlled by the Intel chipset driver. While the motherboard does have a Jmicron chip, this only handles the card reader.

I thought the same as you, due to the fact the Jmicron chips commonly control eSata ports. In this case it does not and I don't reckon it would be cost effective to change them.

click this link
The Dell Online Store: Build Your System

go to 17.3" FHD option

click on help me choose
a pop-up window appears
now click compare side by side

now there it is clearly written WLED
now u know why i was saying it

and i think it was obvious
as B+RG LED is their selling point for their laptops
how can they afford to miss it there
if they also had it in xps 17

 

I HOPE YOU ARE NOT IMPLYING THERE IS A FLAW IN THE PROCESSOR.

Whilst Sandy Bridge is the codename given to the processor architecture, the actual flaw is found in the Chipsets associated with the 2nd generation Intel cores - the i5 and i7.

It is the P67 and H67 motherboards that have the problem, and you can still widely buy the new processors from retailers that bought in bulk, hell you can still buy the motherboards from most places, and as usual - you can still RMA it.

 

Yes, we know where the problem lies.

Sorry, I was typing fast whilst on the phone - I was referring to:

2nd generation Intel® Core™ i7-2630QM processor 2.00 GHz with Turbo Boost 2.0 up to 2.90 GHz [Included in Price]
2nd generation Intel® Core™ i7-2720QM processor 2.20 GHz with Turbo Boost 2.0 up to 3.30 GHz [Add $125.00 or $4.00/month1]
Increase Efficiency
2nd generation Intel® Core™ i7-2820QM processor 2.30 GHz with Turbo Boost 2.0 up to 3.40 GHz [Add $325.00 or $10.00/month1

These options on that link - I'm presuming (perhaps incorrectly, but there has to be some way to differentiate the new mobos given the older ones are being kept in the market) that the new boards will have different names. e.g. i7-3630QM or i7-2630PM.

I'm not clued up enough to know which parts of the name refer to which parts of the mobo / chip [apart, obviously for i7 & the speed ] or which "bit" of the name would change.

But change it must, or you won't be able to tell if you've a proper new one or an old smelly one, which is important when there's original 1st gen "broken" models still available. E-Bay alert! ;0

 

The names will not change.

the i7-2630QM,/ i7-2730QM etc are the names of the sandybridge processors.
There is no problem with these.

The chipset/motherboard is where the problem lies. Cougerpoint on desktop (H67, P67) and huron river on mobile (HM67, PM67)

The names of these will not change either.

There are ways to tell if you have an affected part.
One is by the revision number of the board as this will have changed.
Two is by using an app that detects if you have an affected board.
Gigabyte has released one that works on all sandybridge boards.

Gigabyte Releases Cougar Point SATA Bug Checker - Softpedia

 

Ye, I think we're missing each other's point here though.

Interesting - but very useful link.

My assumption on renaming was due to the mobo never being listed in options you get via online stores [at least from Dell]; purely from a sales point of view, Dell etc are going to want to be able to say "the NEW and 100% WORKING version" to avoid suspicions over the re-entry of the old boards.

That link is invaluable, but entirely pointless if you've just bought a laptop via a 3rd party retailer or ebay, and run it to see you've been sold a 1st gen "broken" mobo. Apart from proof so you can return it...

I incorrectly assumed the QM part was something to do with which mobo was being used - the 2 part being "2nd generation"??


huron river on mobile ( HM67, PM67)

e.g. i7-2730 QM

i7 - quad core
2 - 2nd gen
730 - speed
QM - mobo iteration -- Dell's own version of the HM/PM above??

e.g.

i7 840QM

i7 - quad core
840 - speed
QM - mobo iteration

That was how I assumed it was working as a naming convention. So, er.. what does the QM stand for?

 

I thought the QM indicated Quad Core Mobile CPU, I may be wrong.

MM

 

Hmm... slightly more prosaic than I expected.

 

@Manicminer you are correct dude
QM stands for quad core mobile
for eg:-
i7-2720 QM
i7 - is the type of processor
2 in 2720 stands for 2nd generation
720 is usually the product its replacing
for eg:-
i7-2720 will be replacing i7-720 QM
i7-2820 will be replacing i7-820 QM

720 isnt the speed its just the model no.

QE stands for quad core embedded

there is no problem with sandy bridge processors but rather with their chipsets
h67 and p67 for desktops
hm67 and pm67 for laptops
its has problem for the sata ports 2 to 5
so the port o and 1 remains unaffected
the metal-oxide layer of the PLL transistor for the 3Gbit/s circuit was constructed too thin n gradually der performance degraded as a result of high stress
so the two 6gbit/s ports are fine
according to what intel said its performance degrades by 3%
in a year or so
dont worry intel has rectified the problem
and also has started production for it
it will start its shipping in late feb
and full fledged production will be from april

 

Hi I have just ordered a xps 17 1920 x 1020 gt555m no 3D as it has no optimus and I concerned about heating and stock delays, it has 2 ram slots. I have got the 2730qm CPU and have heard that it is compatible with ddr3 1600 ram. Can I upgrade this system to say 2x8 gig ddr3 1600 ram? Are there any issues with that and what would be the best way of doing that? Any advice would be appreciated. Thanks

 

do you have the 2630 or the 2720?

2630 = 1333Mhz
2720 = 1600Mhz

if im right also it depends on if dell accepts 1600mhz on their mainboard.

btw 8gb ddr 1600 ram? won the lotery? it cost you more then what the laptop price is. about €900 euro each 8gb stick.
