My laptop has 4GB of RAM, which I haven't felt the need to upgrade since I bought it six years ago, but I've been thinking recently that maybe I might, so what I'd like is to get a stick of exactly what I have now. The laptop has room for such an addition and if the sticks are exactly the same there's that much less risk of incompatibility.
But.... a 4GB stick of DDR3-1333 (PC3-10600) 1.5V made by Ramaxel is just not something anyone can sell me. They all want to give me Kingston DDR-1600 1.3V, which might work, and it might not, and even if it did I'd probably have to buy two and replace the old stick rather than add one...
Both Taobao and Amazon.cn have exactly what I want listed but seemingly by one-off noname sellers without a track record.
Surely there are better ways to buy older generation hardware?!?!?!?
