It's not switchable in Dell's case as they only bundled i7 quad core with GT435M.

I originally planned to get the XPS 15 without OS and install Ubuntu with it.
So, I have done some simple research for drivers.
Even if ubuntu failed to recognize GT435M, driver can be easily obtained from NVIDIA so no worry.
Download link for 32-bit: LINUX DISPLAY DRIVER - X86
Download link for 64-bit: LINUX X64 (AMD64/EM64T) DISPLAY DRIVER
For Intel 6200/6300 wireless adapter, refer to Intel's wireless projects for Linux

Too bad, buying from Dell online must have the OS installed.
So, I decided to go if Win 7 and run ubuntu in Virtual Machines rather than a clean install for the time being.

My suggestion are:
1. Make sure you've not pay a single cent to Dell
(Once Dell received and confirmed the payment, they'll build the system as stated by your current quotation that's bad)

2a. If you've received a quotation email from Dell, you may try contacting the sales person as stated in the quotation.
The person might be able to revise your quotation.
Just double check the pricing and specification before proceeding.

2b. Otherwise, cancel your current order then resubmit a new order with the new specification.
As resubmitting a new order would at worst affect only your delivery date, that's better than having your order screwed up and paying for something that's not what you wanted.

Yes, that's I am meant.
Thanks for clarifying.
Once you paid, they build so it might not be possible to change/alter the specification anymore.

Good news for me again lol...
Seems like Dell is finally picking up pace.
They started to ship my XPS from factory.

Current Status: Ship From Factory
Estimate Delivery Date: 09-Dec-2010

Thanks.
I'm planning to get some notebook accessories for my XPS.
Just wondering it is necessary to have a notebook cooler for XPS?
Will the laptop heat up too much if used in non-air-conditioned room?

Cool, I'm planning on getting CM U2 as well.
But, when I looked at the measurements for U2, the width of U2 seems to be slightly less than XPS 15.
Can you confirm that?

But U3 can't be fitted into a 15.6" laptop backpack right?
What a dilemma... as I wanted to bring the cooler together with the laptop...

I guess it's really down to personal preference.

I like CM U series because it's highly portable and fans can be added later.
Yeah, having too many fans might cause noise issue.

I've also looked at those with a single huge fan (12/14cm etc) but it hardly appeals me in looks and portability.

Thanks for the link.
I've not go into minor details such as webcam, brightness adjustment, etc when I planned on using ubuntu on XPS 15.
I assumed that ubuntu would be able to take care of these easily other than drivers for components such as GC or WiFi.
Well, I guess Dell forcing me to use Win 7 for the time being isn't really that bad until ubuntu community manage to solve these issues.

The hugeness of the CM NotePal U3 really makes it hard to fit in laptop bag...
420 x 320 x 65 mm

If I buy that that means I will have a hard time fitting it into a bag to carry aorund

That's why I'm looking for a potential bag that can fit both XPS 15 and U2
Over here : Dicota Laptop Bags

Base system is the RM3499
My upgrades are:
1. Anodized Aluminium LCD Back Cover (for WWAN/6300 wireless/Tv tuner)
2. 15.6 FHD (1920x1080) B+RGLED display with TrueLife™
3. 8GB Dual-channel 1333MHz DDR3 SDRAM (2 x 4G)
4. Intel Wireless Network Card 6300
5. Dell™ Backlit Keyboard with Touchpad
6. Genuine Windows® 7 Home Premium 64bit (English) DVD Media

For XPS 15 alone, a 15.6" bag would fit nicely.
For XPS 15 and U2, 16.4" and or greater might do the trick
For XPS 15 and U3, you have to live with limited number of overly huge, ugly and heavy bags for 18" and above

Yes, RM4457 to be exact.

My potential bag for XPS 15 and U2
1. Dee Messenger
2. Dee SlimCase
3. SmartSkin

All 3 are locally available.
Some LYN members selling too.

I ordered mine on 29th/30th Nov as well and my current EDD is 9th Dec.
So, it make sense for makubexong and my EDD to be close together.
Difference is I customized more options than him so I guess the number of customizations doesn't matter.
More likely to be Dell is finally on track with their production line.
Just need to check whether will Dell postpone the EDD.

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

Anyone here ordered the Belkin Evo 4G backpack?
Need some comments to decide whether to keep it or get another one. Thanks.

Moments ago, I received a SMS from Dell saying that the delivery is on 8th Dec.
So far, no confirmation call from Dell.

Tomorrow is Awal Muharram.

1-2 C increase is for:

1. Idle temperature
2. Full load temperature
3. Both
4. None of above

Please answer based 1, 2, 3 or 4.

If the answer is 2 or 3, then GT435M users might do something similar to NVIDIA (refer: click here)

No special RAMs required for dual channel to work.
Just need to fill up a pair of RAM slot with any RAM then it will work as normal.

As laptop mostly have only a pair of RAM slot, filling that up means u get dual channel by default.

For PC, motherboards normally have at least 2 pair of RAM slots. (Usually each pair is colour coded for easy recognization)
So, they need at least one pair of RAM for dual channel.

e.g. S? - Slot?, F - filled, X - unfilled
S1{A} S2{B} S3{A} S4{B}
1. F X F X
2. F F F F
3. F X X X
4. F F X X
5. F F F X
6. F X F F

Only 1 and 2 are in dual channel config. (3 to 6 are not)

@farisiylia, congrats

Seems like XPS 15 users keep on growing
