What happens: Works fine with 16GB. With 32GB, powers-on but screen is blank. Tried second laptop (also ivybridge) and found same.
Laptop: W110ER with i7 3820QM Ivybridge cpu and Win7 server 2008 R2 standard SP1. http://www.notebookcheck.net/Review-Clevo-W110ER-Barebone-Subnotebook.75104.0.html see current cpuz http://valid.x86.fr/0fbz5t
Memory: 32GB DDR3 1867 MHz SO-DIMM Memory Kit (2 x 16GB)

- Found them on amazon https://www.amazon.com/PACCOM-RAM-Kit-1867MHz-Modell2015-Skylake/dp/B018IQ41H0/ref=sr_1_3?m=A9FV3DH73W9DT&s=merchant-items&ie=UTF8&qid=1485671863&sr=1-3
Background: The W110ER (for reasons I don't know) supports 16GB (2 x 8GB modules) of 1600 DDR3. In the past I have learned that often the max ram is simply what the mfg thought was the most ram anyone would put in the laptop or was available at the time of product launch (I had an HP with a spec max 2GB of RAM and later found that 8GB worked fine, it was an x32 OEM). So, I ignore the RAM specs. Right now, I am running 16GB of 2133 DDR3 RAM underclocked slightly to 2128 (spec is 8GB 1600 mhz max and 16GB 1333 Mhz max).
A little research:
- search for max memory support for ivybridge found 32GB https://ark.intel.com/products/64889/Intel-Core-i7-3820QM-Processor-8M-Cache-up-to-3_70-GHz?q=3820QM
- search for max memory frequency for ivybridge found DDR3 1600 (same link as above) but speeds up to 2133 have been tested to work https://en.wikipedia.org/wiki/LGA_1155
- I might fall under the 'your motherboard just does not support 16GB modules' like this case Can I upgrade laptop memory to 32GB of RAM? there they suggested reading this https://en.wikipedia.org/wiki/RAM_limit but I did not see much helpful in that wiki page. This 16GB module compatibility sheet seems to exclude ivybridge for unclear reasons http://www.intelligentmemory.com/fileadmin/download/compatibilitylist.pdf
- this superuser post says to check voltage between motherboard and RAM using crucial site as a check Laptop won't boot with RAM upgrade Crucial (http://www.crucial.com/usa/en/scanview/0A93A6CF31D926C3) shows all 1.35v memory and 32GB kit is 1.35v so checks out.
- this super user comment says a mother board can just be picky about top RAM speeds Laptop won't boot after installing new RAM (compatibility issue?) the 32GB kit is 1866 and I am currently running 2133 so speed is not the problem.
Test: I installed each 16GB module individually and had same lights on no screen response.
What I want to know: Why won't the laptop boot and what do I do to get it to boot?
