8 or 16GB of RAM for i7-820QM Processor?

[idata]

it seems as if a Intel® Core™ i7-820QM Processor

supports a total 16GB of RAM as this option is available when ordering a Thinkpad W701ds from http://shop.lenovo.com/ http://shop.lenovo.com.

16 GB PC3-10600 DDR3 SDRAM 1333MHz SODIMM Memory (4 DIMM)

In contrastr Intel's processor specification indicates the Max Memory Size to be 8GB, but it also indicates that this is dependent on memory type.

http://ark.intel.com/Product.aspx?id=43124 http://ark.intel.com/Product.aspx?id=43124.

The question arises: what is true, both?

I would assume that since the lenovo on-line shop provides the option of 16GB total RAM that the besaid processor can handle it and thus is not limited to 8GB of RAM.

Would be nice to receive a clear statement from Intel clarifying the effects of the memory type installed.

Hope to see such a statement soon or any other forum feedback.

Thanks, Hans.

Well, I was going to give you a "good answer" but now I am not so sure.

The processor spec sheet confirms the Ark posting.

http://download.intel.com/design/processor/datashts/320765.pdf http://download.intel.com/design/processor/datashts/320765.pdf page 12 lists the processor memory support.

Possably the Lenovo laptop supports more than just this processor so it has additional slots for 4 DIMMS?

Or they have some slick new 4-GB device technologies (never heard of them, but I don't keep up with laptop improvements )

I would recommend asking Lenovo. They may know something I don't.

Checked Cruicial site and they say 2 slots. http://www.crucial.com/store/listparts.aspx?model=ThinkPad%20W700ds%20Series http://www.crucial.com/store/listparts.aspx?model=ThinkPad%20W700ds%20Series

(Based on this specification I don't see how they could used 4 DIMMS with this processor.)
