While performing reviews, I was asked to review a question that basically asked "Will DDR3 RAM work with motherboard XYZ?".
For the purposes of Super User, is this considered a hardware recommendations question?
In some ways, I see it as so: the OP is asking for which hardware will meet their needs.
On another way, I see it as not: the OP is not asking for any specific RAM modules to purchase; they are simply asking whether or not DDR3 RAM is compatible with a particular motherboard.
Note that such questions can typically be answered by (simply?) finding the manual for the motherboard online. But for this Meta question, let's just focus on the narrow query asked above.
