Hi,
Zitat von Arthur Heymans arthur@aheymans.xyz:
TL;DR - Has anybody either successfully used 16GB DDR3 modules on SandyBridge, can rule it out, or has ideas about how to dig deeper?
According to Sandy bridge datasheets only up to 4GB DDR3 technology is supported, which makes it possibly to use dimms with 2 ranks, with each rank having a capacity of 4GB, hence max 8GB per DIMM. This is a hardware limitation.
Thank you for your answer. That's what I also read, but here it is stated that some Asus Sandy Bridge boards support such modules:

Is Sandy Bridge E so different from Sandy Bridge? Would it be possible
Sandy Bridge E are high end desktop/server CPUs that have a different socket (lga2011) and likely a different memory controller (4 channels instead of 2). A quick look at datasheet says nothing about maximum rank size.
to replace the 2620QM with an Ivy Bridge CPU?
Afaik that should be possible since the CPU is socketed on that model but won't overcome your issue. (same limitation)
Best,
Thomas
