Faulty and had to be returned,
Verified Purchase(What is this?)
This review is from: Integral 4GB DDR3-1600 SODIMM CL11 Laptop Memory Module (Accessory)
Good spec and price but it didn't work (just got blue screen of death as soon as Windows started). Supplier refunded purchase cost on return, I would have tried another as RAM can be temperamental but I bought the last one in stock...
