That was my thinking too, but Intel's specs also says: (dependent on memory type)!
However, page 10 of HP's EliteBook 8740w laptop Service Manual http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c02114152/c02114152.pdf clearly states:
So is why would HP and IBM sell 16GB of RAM with their laptops if it is not supported by the Intel processor?
Can Intel confirm that Max RAM limit for the I7-720QM is indeed 8GB and not 16GB and let the hardware vendors know about this so they can correct their manuals and ordering systems?

Here is the link to Lenovo's ThinkPad w510 technical specifications which also clearly states support for 16gb of memory!

I can only speculate that the 16 GB maximum rating pertain to the motherboard use in their computers. That is, their motherboard can accomodate 16 GB but this should be match with a processor that can handle that much of memory. Why not chat with their tech support for clarification?
Added: If you click this link and make some comparison you will find that the I7 mobile processors have a max rating of 8 GB while the desktop I7 processors have a max rating of 24 GB.
The 8 GB reported on the ARK website, indicates that the processor supports only a maximum of 8 GB:
So, even if the laptop supports 16 GB, the processor will only be able to recognize 8 GB.
Unfortunately, Intel cannot control the advertisements provided by third party companies. In these situations my best recommendation would be to check with the device manufacturer, like in this case with the processor manufacturer, so we can confirm to the customer the limitations of the processor before buying any computer system.
I discovered that many customers have 16GB Lenovo laptops with useable memory given right BIOS.
So Intel Web should udpdate its specs! ;^)
The mystery is solved! I received a different answer from Intel pre-sales support which says the I7 Mobile processor may support 16GB...
Here it is:
Thank you for your recent email. I understand you are interested in the I7-720QM memory support. Please use the following link to review the details of the I7-720QM.
At the bottom of the page you will notice that there is an Intel boxed version and an Original Equipment Manufacturer (OEM) version of the i7-720QM.
Please contact the manufacturer of your computer for information. The Original Equipment Manufacturer (OEM) may use their own specification of power supply, chassis, motherboard, and/or cooling system. For this reason we are unable to provide information on the OEM version. The manufacturer of your system may be able to provide you with this information. The OEM may also be able to provide you with purchase information on compatible products.
Hope this helps!
How much ram is supported by the Intel boxed processor and how much for the Intel Oem processor? I can't find the specs for these processors in the Intel website.
Additional questions: Are these processors (boxed and Oem) custom built by Intel for the different vendors? How are they different from the official one?
You need to talk to Intel pre-sales support to get the details...
You will find the info here: http://ark.intel.com/Product.aspx?id=43122 Intel boxed processor is 8gb maximum.
At the bottom of the web page under "Ordering and Sampling Information", you find 2 ordering code/part-number. One is boxed Intel and the other is OEM processor. According to Intel, you have to get the details specs for the OEM processor from the laptop vendor. This is pretty much all I know.
Here is the link to Intel's Product Order Code Number (Boxed vs OEM code): http://www.intel.com/support/processors/mobile/corei7/sb/CS-030872.htm
My guess would be to use the vendor's OEM processor to ensure compatibility. But what do I know .
I am still not convinced that Intel would manufacturer 2 different version of a processor - Boxed and OEM.
I am hoping that some Intel Support person will jump in this thread and confirm the above statements!
