Hi Iru, From T420 manual [1]: "Memory: Up to 8GB DDR3 - 1333MHz (2 DIMM Slots)"
While it seems possible to use 16GB (2x 8GB), it isn't possible to use 16GB DIMMs. I haven't tested by myself, but it seems like a hardware limitation. Please provide raminit logs, just to make sure.
Hi,
it is often not but the manuals are just reflecting what the vendor has tested. Very often these test are not extended once bigger DIMMS become available hence the documentation is not reliable at all. The only hardware limitation I am aware of that could interfere is what the northbridge supports... http://ark.intel.com/products/52229/Intel-Core-i5-2520M-Processor-3M-Cache-u... So unlike the manual (the "Up to 8 GB" are meant as total) 16 GB is the maximum. The question remains if a single channel can address the whole range but given that it does not make sense economically that point is rather moot anyway.
