Don't know why the picture shows two sticks. Different picture than when I bought mine. I would contact the seller just in case though. Would not want to receive (2) 4GB sticks instead. **Q: Do you ship to singapore?** A: We do if you pay the DHL shipping cost **Q: I have sk hynix 8gb 1rx8 pc4 2666v sa1 11 hma81gs6afr8n vk no ac, I ordered this/got 8gb 1rx8 pc4 2666v sa1 11 hma81gs6cjr8n vk no ad will this work?** A: Yes. They are the same. Just from a different batch. **Q: Does hma81gs6jjr8n-vk is the same as hma81gs6cjr8n-vk?** A: What do you mean by 200mhz difference. This is what I have in my Dell laptop (jj not cj) and when I pull the serial # and run it, it comes up as DDR4 SODIMM 2666mhz. I want to double my RAM and use dual channel. So what's the difference? And does that mean dual channel won't work? ## Customer Reviews ### ⭐⭐⭐⭐ As described *by A***T on 26 November 2019* As described ### ⭐⭐⭐⭐⭐ Worked the way I wanted *by W***K on 18 January 2020* I got this ram stick specifically because my laptop came with the same.
