## Questions & Answers

**Q: Is this one dimm or two?  two are pictured.**
A: The listing is for 8GB single stick of RAM.  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?
