According to the HP site, my i7-4610M HP zBook will only support 16GB RAM :(.

http://www8.hp.com/us/en/campaigns/workstations/zbook-17.html

However, the specs for that processor according to Intel indicate that it supports 32GB.

http://ark.intel.com/products/80345/Intel-Core-i7-4610M-Processor-4M-Cache-up-to-3_70-GHz

In addition, the manual for the zBook says:

The computer has four memory slots. Expansion memory slots are located in a compartment on the bottom of the computer. Primary memory slots are located under the keyboard.

So, it could potentially use an 8GBx4 configuration without the need to support 16GB chips. I want to place an order to expand my memory to its' max. capacity. Should I get 2 or 4 8GB modules?

  • Where on the first link do you see it being restricted to 16 GB of RAM? I cannot find any such reference, even searching for the string, "16". Nov 13, 2015 at 20:51
  • The link is for the 2015 ZBook. You have the 2013 ZBook. The specs for the 2015 are totally irrelevant.

  • Sorry, if you expand the section "Full specs for G2" you see : 32 GB maximum memory with quad-core processor. 16 GB maximum memory with dual-core processor. And the "Available processors section in those full specs, "Intel® Core™ i7-4610M with Intel HD Graphics 4600 (3 GHz, up to 3.7 GHz with Intel Turbo Boost Technology, 4 MB cache, 2 cores) @ChrisInEdmonton

I did post a few links to the research I had done, and clarified one commenter's confusion about them, so I don't understand the downvoting of this question. However, with further research, this turned out to be really easy to determine, even without an external utility. From a command prompt, simply type:

wmic memphysical get MaxCapacity, MemoryDevices

which produced the following output for my new laptop:

MaxCapacity  MemoryDevices
16777216     2
-1

The link you posted says the maximum memory is 64gb:

enter image description here

The maximum supported by your processor is 32 GB:

enter image description here

You always have to go with your biggest limitation which in this case is the processor. So you are able to get DDR3L 1333 or DDR3L 1600 at a maximum capacity of 32 GB total. This means that your 4 sticks of 8 GB (8 x 4 = 32) would indeed work.

  • Why the downvote? I answered his question correctly with explanation.
