Dell Precision M6500 memory upgrade
precision M6500 spec sheet says it supports upto 8gb DDR3 1600MHz ram. I was wondering if that 8gb can be one 8gb module or does it have to be 2 x 4gb modules? The laptop has 4 DIMM slots available.
Thanks

The memory controller on the Core CPUs is aboard the CPU itself. Here are Intel's specs:

I am talking about 1600MHz speed ram. The laptop supports 32gb (4x8gb) for 1333MHz ram. But for 1600MHz speed it only supports up to 8gb ram. I was wondering if that can be 1 8gb module.. Did you understand my question? Mine is a quad-core.

Max is 8G/slot or 32 if you have a quad-core CPU (the four-slot system should have shipped with a quad core).
A dual-core CPU is 8G max total.

What model CPU do you have? The CPU determines the RAM speed.

This CPU will not run memory at 1600 MHz -- max is 1333, so it's a moot point about DDR3-1600 support.
Even if you install DDR3-1600, it'll just downclock to 1333 MHz.

how do you determine that?
