Hi,
i would like to ask you about RAM to G750JZ. I installed 16Gb 2133MHz(2x8Gb) 1,35V to G750 . System runs perfect... Is it possible
install next 16Gb 2133MHz (to max. 32Gb)? I got problem, than if I add this next modules to G750, system i unstable.....blue death !!
Have you got some advice how to fix it? or this max. capacity 32Gb is only for 1600MHz?

THX

The max. memory limit of 32GB only applies to either DDR3L-1333 or DDR3L-1600. The IMC of the 4700HQ isn't capable of running 32GB of DDR3-2133, at least without increasing DRAM and/or IMC voltages, including loosening the timings if necessary. And because the BIOS/UEFI of our boards doesn't offer any of those options, you're limited to the max. rated capacity and speed of 32GB DDR3L-1600.

redduc900, apparently some modules do work at 4 x 8GB x 2133/1866:

Hass36D, what make/model / part number is your 2133?

It is possible that you have 1 or 2 out of spec SODIMM's, you can play with swapping out the 2 good ones, and try to find the 1 or 2 bad ones. Think about it, and work up a sequence to test to find the bad SODIMM, RMA it, and get another good one, it can work :)
