When I got the X250, there was one letdown: supposedly the thing maxed out at 8 GB of RAM. But then things turned around. In April a BIOS update landed that added support for a single 16 GB stick. The only problem was that RAM was expensive as hell. Prices have come down now, but Taobao is out of stock everywhere. There are some cheap ~600 RMB single 16 GB DDR4 sticks floating around, but the X250 can’t use them — it’s DDR3 only. Good thing overseas shopping exists. US Amazon had a decent deal, so I grabbed a single 16 GB Micron DDR3 stick. Global shipping isn’t actually that fast, for the record.
